Food groups and risk of all-cause mortality: a systematic review and meta-analysis of prospective studies

Dietary intake of total, animal, and vegetable protein and cardiometabolic risk factors in patients with type 2 diabetes: using iso-energetic substitution models

Objectives

The present study aimed to examine the effects of dietary intake of total, animal-based, and vegetable-based protein on cardiometabolic risk factors in diabetic patients, using iso-energetic substitution models.

Methods

This cross-sectional study was a part of the Ravansar Non-Communicable Disease (RaNCD) cohort study with 8,894 subjects. Univariate and multivariate logistic regression models were used to determine the associations between total, animal, and vegetable protein intake (per 5% energy) and cardiometabolic risk factors. All analyses were carried out at a 95% confidence level using STATA software version 14.2.

Results

In diabetic patients, higher intake of total protein increased the risk of hypertension by 2.48 times compared to the reference group (p = 0.03). Besides, the association between the consumption of one unit of energy (5% energy) from protein at the expense of one unit of energy from fat and the risk of cardio-metabolic risk factors, showed an increase in dyslipidemia and CVDs by 65 and 48%, respectively. The substitution for carbohydrates also causes a reduction in obesity and abdominal obesity by 28 and 53%, respectively.

Conclusion

In diabetic and non-diabetic patients, different associations were observed following the substitution of protein. In diabetic patients, the substitution protein for fat increased the risk of dyslipidemia and CVDs and carbohydrate replacement increased the risk of dyslipidemia. The highest vs. the lowest intake of animal protein decreased the risk of obesity and abdominal obesity, whereas regarding plant protein a direct link was found with dyslipidemia. However, prospective studies are needed to clarify the cause-and-effect links.

Health and environmental dietary impact: Planetary health diet vs. Mediterranean diet. A nationwide cohort in Spain

BACKGROUND

Plant-based diets, such as the Planetary Health Diet (PHDI) and the Mediterranean Diet (Med), offer notable advantages for human and planetary health. However, knowledge on the PHDI's benefits is limited, particularly in Southern European countries where the Med is culturally rooted and is an environmentally sustainable dietary pattern.

OBJECTIVE

to evaluate the association of both PHDI and Med with mortality and assess their environmental burden in the adult population of Spain.

METHODS

Data were taken from the study on Nutrition and Cardiovascular Risk in Spain (ENRICA) comprising 13,105 participants representative of the Spanish adult population. The PHDI score (0-140 points) was based on 15 food groups, while adherence to Med was assessed with the 14-item MEDAS score (0-14 points). Environmental impact was assessed using the SHARP-ID database (including greenhouse gas emissions and land use). Analyses were performed with Cox regression and adjusted for main confounders.

RESULTS

During a mean 14.4-year follow-up, 1157 all-cause deaths occurred. The mortality hazard ratio (95 % CI) for the highest vs lowest tertile of the PHDI score was 0.78 (0.66, 0.91) but reached a plateau level at 90 points of PHDI. For the MEDAS, the corresponding results for the highest vs lowest tertile was 0.79 (0.68, 0.93) with a continuous inverse dose-response association. Adherence to some components of the PHDI (fruits, dairy, and unsaturated oils) and of MEDAS (nuts, and low consumption of soda and pastries) was independently and significantly associated with lower mortality. Results remained robust in sensitivity analyses. In terms of environmental impact, both plant-based diets had similar low footprints, with dairy and meat products being the largest contributors.

CONCLUSION

In this large cohort of Spanish adults, higher adherence to the PHDI and MEDAS was similarly associated with lower all-cause mortality and showed comparable low environmental impact.

Ultra-processed foods and coronary artery disease severity: a cross-sectional study of at-risk normal-weight and overweight patients undergoing elective angiography

INTRODUCTION

There is growing interest in the connection between ultra-processed food (UPF) and cardiovascular diseases. This study explores how UPF intake relates to the severity of coronary artery disease (CAD) in at-risk patients undergoing elective angiography.

METHODS

Data covering demographic, and clinical details, and dietary intakes (using a validated food frequency questionnaire) were gathered from the Nutrition Heshmat Registry (NUTHER) in Rasht, Iran. UPF consumption was evaluated using the NOVA food classification system, with the exception of core grain foods. The study comprised 1,015 participants, who were classified based on the severity of CAD using the Gensini score (severe-CAD = Gensini score ≥ 60). Logistic regression was used to analyze the odd ratio (OR) and 95%confidence interval (95%CI) for severe-CAD across UPF quartiles (percentage of energy), and for each 10% increase in UPF intake. Restricted cubic spline (RCS) regression was employed to explore nonlinear relationships between UPF and severe-CAD.

RESULTS

Following controlling for potential confounders, normal-weight participants in the highest quartile of UPF exhibited about 5 times greater odds of severe-CAD than those in the lowest category (OR(95%CI): 5.01 (1.89, 13.29); P-for-trend = 0.002). Overweight/obese participants in the higher UPF quartiles had approximately 2-3.5 times greater odds for severe-CAD than those in the 1st quartile (ORs (95%CIs): 3rd quartile 1.91 (1.14, 3.21); and 4th quartile: 3.53 (2.07, 5.99); P-for-trend < 0.001). Each 10% increase in daily energy intake from UPF was associated with about 1.6-2 times increased severe-CAD risk among overweight/obese and normal-weight individuals (ORs (95%CIs) of 1.64 (1.28, 2.11), and 2.24 (1.24, 4.05), respectively). RCS analysis showed an upward trend toward higher UPF intake in relation to increased risk of severe-CAD (P-for-overall-trend < 0.0001; P-for-nonlinearity = 0.005).

CONCLUSION

The findings obtained underscore a direct association between UPF and the risk of CAD progression among at-risk patients, independent of BMI. However, further prospective studies are essential to confirm these results and better understand this relationship.

Dietary patterns and all-cause and cardiovascular disease, and cancer mortality in Korean adults

BACKGROUND

Examining dietary patterns in relation to mortality offers a more comprehensive view of food and nutrient intake. However, to our knowledge, the association of the Korean population's dietary patterns with mortality remains scarce and unclear. We aim to investigate the association between dietary patterns and all-cause, cardiovascular disease (CVD), and cancer mortality in the Korean population.

METHODS

This prospective cohort study included 18,019 men and 26,604 women aged ≥ 19 years who participated in the Korea National Health and Nutrition Examination Surveys 2007-2015. Dietary data were collected from a 24-hour dietary recall. Mortality from all causes, CVD, and cancer were ascertained from linkage to Statistics Korea. We identified dietary patterns through factor analysis. Cox proportional hazard models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) of the all-cause, CVD, and cancer mortality according to diet pattern scores.

RESULTS

During a mean follow-up of 8.19 person-years, 2,622 deaths were identified, with 595 due to CVD and 827 due to cancer. Factor analysis based on 22 food groups, three dietary patterns were obtained: (1) "animal food and condiment pattern," (2) "seafood and vegetable pattern," and (3) "dairy products and processed meat pattern." After multivariable adjustment, the "seafood and vegetable pattern" score was associated with a lower risk of all-cause and CVD mortality. HRs (95% CIs) for all-cause mortality for the second to the highest quintile of "seafood and vegetable pattern", compared with the first quintile were 0.86 (0.75-0.99), 0.75 (0.65-0.87), 0.81 (0.69-0.94), and 0.87 (0.73-1.05), respectively (P for trend = 0.191). For CVD mortality, the HRs were 0.82 (0.62-1.07), 0.80 (0.58-1.08), 0.70 (0.50-0.99), and 0.63 (0.42-0.96), respectively (P for trend = 0.027). No statistically significant associations were found in "animal food and condiment pattern" or "dairy products and processed meat pattern" for all-cause, CVD, and cancer mortality.

CONCLUSIONS

We observed that the "seafood and vegetable" dietary pattern decreased the risk of all-cause and CVD mortality in Korean adults.

MUSAE: Fusion of art and technology to address challenges in food and health

There is an urgent need to transform our current food system to improve population health/wellbeing and planetary health. A number of challenges exist in order to achieve this. Artists, with their innate ability to use imagination to envision future needs and solve problems, represent a key group in this transformation. The project MUSAE brings together artists with experts from different disciplines to define an innovative model to integrate artistic collaboration in the (European) Digital innovation hubs (E-DIHs). They will employ the Design Futures Art-Driven (DFA) methods to enable artists and a range of companies involved in food production and distribution to develop innovative products and services that address key issues in the food system. MUSAE will run two residencies involving 23 artists and 11 SMEs working with three main technologies-Artificial Intelligence, Wearables and Robotics-to envision the future scenarios for societal needs and technology applications, as well as develop future-driven prototypes, thus opening new markets and innovations in the area of food.

The association between overall, healthy, and unhealthy plant-based diet indexes and risk of all-cause and cause-specific mortality: a systematic review and dose-response meta-analysis of prospective cohort studies

Background: recent dietary guidelines recommend a diet that mainly includes plant-based foods and a moderate amount of animal products. Therefore, we hypothesized that plant-based diet indices (overall plant-based diet index (oPDI), healthy plant-based diet index (hPDI), and unhealthy plant-based diet index (uPDI)) might be associated with risk of all-cause and cause-specific mortality. Methods: a systematic review was conducted using PubMed, Web of Science, Scopus, and Embase databases until December 2024. Meta-analysis was performed utilizing random-effects models to calculate relative risk (RR) with the corresponding 95% confidence intervals (95% CIs). Results: from 436 initial records, 25 prospective studies met the inclusion criteria. The findings of our study indicated a modest inverse association between the adherence to oPDI and risk of all-cause mortality (RR [95% CI]: 0.89 [0.83-0.94]; n = 15 studies) as well as mortality related to cardiovascular diseases, chronic heart disease, and total cancer. Also, adherence to hPDI was found to reduce risk of all-cause (RR [95% CI]: 0.86 [0.82-0.90]; n = 21 studies), cardiovascular disease, chronic heart disease, total-cancer, and prostate cancer mortality, whereas uPDI was associated with higher risk of all-cause (RR [95% CI]: 1.20 [1.13-1.27]; n = 19 studies), cardiovascular disease, chronic heart disease, and total-cancer mortality. Our dose-response meta-analysis showed a monotonic inverse association between adherence to oPDI and hPDI and a positive linear association between adherence to uPDI and risk of all-cause mortality. Conclusion: our findings highlight the importance of evaluating the quality of plant-based foods as either healthy or unhealthy in relation to the risk of all-cause and cause-specific mortality.

Metabolome of different cultivars of peas, lentils, faba beans and lupins - An 1H NMR spectroscopic exploration of their sensory attributes and potential biofunctionality

The transition to a more plant-based diet embraces a higher consumption of diversified pulses. Understanding the chemical composition of pulses is crucial to decipher their biofunctionality. This study analyzed 14 different cultivars of 4 types of pulses (pea, lentil, faba bean, and lupin) using NMR-based metabolomics. Sucrose, glutamate, and citrate were the metabolites representing the most abundant polar chemical classes (carbohydrates, amino acids, and organic acids). Lupin had a higher content of carbohydrates, and a lower content of free amino acids than the other species. Differences among the cultivars related to carbohydrates were found for peas and lentils, which was reflected in variations in their metabolic pathway potential. Faba beans showed highest concentrations of phenolic compounds. Correlation with data from descriptive sensory profiling enabled pinpointing several amino acids and some organic acids that contributed to explain variations in perceived smell and taste among the cultivars.

Umbrella Review of Systematic Reviews and Meta-analyses on Consumption of Different Food Groups and Risk of All-cause Mortality

Consumption of different food groups is linked to a range of health outcomes. It is essential to integrate the most reliable evidence regarding intake of different food groups and risk of mortality to optimize dietary guidance. Our aim is to systematically and comprehensively assess the associations between the consumption of various food groups and all-cause mortality. The food groups under consideration include edible grains (refined and whole grains), fruits, vegetables, nuts, legumes, fish and fish products, eggs, dairy products/milk, meat and meat products (including processed meat, unprocessed red and white meat), sugar-sweetened beverages, and added sugars. We present these associations with high compared with low consumption and per serving comparisons. We comprehensively and systematically reviewed a search in Medline, Embase, Web of Science, and Epistemonikos (PROSPERO: CRD42024498035), identifying 41 meta-analyses involving over a million participants, many of which showed significant heterogeneity. Of the 41 studies, 18 were rated high quality, 8 moderate quality, 5 low quality, and 10 critically low quality according to AMSTAR-2 assessments. Our findings revealed that higher consumption of nuts, whole grains, fruits, vegetables, and fish was associated with lower mortality rates, both in high compared with low comparisons and per serving analyses. Similarly, we observed favorable outcomes for legumes and white meat in high compared with low comparisons. Conversely, high intakes of red and processed meats, as well as sugar-sweetened beverages, were linked to higher all-cause mortality. Dairy products and refined grains did not show clear associations with mortality, whereas there was a tendency in all-cause mortality for high intakes of added sugars and eggs.

Impact of school salad bars on fruit and vegetable selection, intake, and waste in Mid-Atlantic elementary schools

BACKGROUND

Few studies have empirically examined the impact of school salad bars on elementary students' fruit and vegetable (FV) consumption within the National School Lunch Program (NSLP). This natural experiment evaluated the impact of salad bars on FV selection, intake, and waste within elementary schools.

METHODS

Seven school pairs, matched on Title I status and percentage of students from ethnic or racial minority backgrounds, were randomly selected. All schools served pre-portioned FV at baseline. One school within each pair received a salad bar; the other continued to serve pre-portioned FV (Control). Digital imagery plate waste methods were applied at baseline and 4-6 weeks after schools installed salad bars (post). Images were rated in the laboratory (ICCs = .94-.99) to determine FV selection, intake, and waste (servings [1 NSLP serving = ½c]). Multilevel modeling evaluated group (Salad Bar vs Control) and time (baseline vs post) differences and group-by-time interactions. Differences in outcomes by Title I status were also examined.

RESULTS

Across schools, mean NSLP participation was 54%. N = 6,623 trays were included (n = 3,273 Salad Bar; n = 3,350 Control). Students in Salad Bar schools selected (+ .44c) and consumed (+ .36c) more FV at post, compared to baseline. Control students decreased FV selection (-.05c) with no change in intake from baseline to post. Group, time, and group-by-time interactions were significant (ps < .0001). When examined separately, results suggest that these effects are driven by fruit. Salad Bar students increased fruit selection (+ .45c), intake (+ .36c), and waste (+ .09c) from baseline to post; no significant changes were observed in Controls. There was no significant change in vegetable selection, intake or waste for either group. Findings did not differ based on Title I status.

CONCLUSIONS

Salad bars were effective in increasing elementary school students' fruit selection and intake, yet did not increase vegetable selection or intake. Additional efforts are needed to increase vegetable intake and minimize fruit waste from salad bars. Consistent findings across schools, regardless of Title I status, suggest potential for salad bars to yield increased fruit intake across socioeconomic groups. Findings can inform policies designed to increase FV intake within the NSLP.

TRIAL REGISTRATION

This investigation reports results of a systematic evaluation of school salad bars and does not meet criteria for a clinical trial, yet was retrospectively registered (10/28/22) in clinicaltrials.gov (NCT05605483) as an observational study.

Intake of fruit, vegetables and pulses, and all-cause, cardiovascular and cancer mortality: Results from a population-based prospective study

OBJECTIVES

The aim of this study was to explore the association of fruit, vegetable, and pulses consumption with all-cause, cardiovascular, and cancer mortality.

STUDY DESIGN

This prospective study included 66,933 individuals from three Spanish health surveys linked to the national death registry up to December 2022.

METHODS

Adjusted Poisson regression models were used to analyze the data, categorizing fruit, vegetable and pulses intake according to Spanish dietary recommendations and using splines to examine non-linear relationships.

RESULTS

No clear association was found between pulses intake and mortality. Consuming fruits and vegetables ≥2 times/day reduced all-cause mortality risk by 20 % (95%CI = 10%-29 %) and 17 % (95%CI = 7%-26 %) respectively, compared with <3 times/week. Combined intake of fruits and vegetables from 1 to 1.99 to ≥5 times/day showed reductions in all-cause and CVD mortality ranging from 16 % (95%CI = 5%-26 %) to 30 % (95%CI = 20%-39 %), and from 25 % (95%CI = 5%-41 %) to 35 % (95%CI = 14%-50 %), respectively, compared with <1 time/day. No additional benefits against all-cause and CVD mortality for intakes of fruits over 2-3 times/day, but gradual reductions in mortality risk for vegetable intake of 2-5 times/day were observed. Combined intake showed protection up to intakes of 10 times/day, notably for CVD mortality. Associations were similar but weaker for cancer mortality.

CONCLUSIONS

This study suggests that significant benefits of fruits and, specially, vegetables intake might go beyond the recommended five servings a day. Confirmation of these results could lead to specific dietary recommendations to prevent chronic diseases.

Social and ethnic-racial inequities of physical accessibility to famers' markets in Porto Alegre, Brazil

Farmers' markets are important spaces for the commercialization of fruits and vegetables, which access by the urban population is considered one of the key aspects of healthy cities. This study adopts an ecological approach with geographic-spatial emphasis to describe accessibility to farmers' markets in Porto Alegre-RS, by four different modes of transport (walking, bicycle, bus, and car) and their associations with income and race/skin color. The distribution of markets across the city is more balanced than other food establishments, although physical accessibility is highly uneven across modes of transport: the ability to reach a market on foot in 10 minutes or less is restricted to no more than 25% of the population, while almost 90% can do it by driving a car. The study found a direct and positive association between levels of accessibility to farmers' markets and income: wealthier areas can reach fairs in less time using any mode of transport than poorer ones (p<0.001). Regions with a majority of white inhabitants have better accessibility to the fairs on foot, by bicycle, and by bus (p<0.01) than regions with a majority of Black, Indigenous, or yellow populations.

Application of machine learning algorithms in an epidemiologic study of mortality

PURPOSE

Epidemiologic studies are important in assessing risk factors of mortality. Machine learning (ML) is efficient in analyzing multidimensional data to unravel dependencies between risk factors and health outcomes.

METHODS

Using a representative sample from the National Health and Nutrition Examination Survey data collected from 2009 to 2016 linked to the National Death Index public-use mortality data through December 31, 2019, we applied logistic, random forests, k-Nearest Neighbors, multivariate adaptive regression splines, support vector machines, extreme gradient boosting, and super learner ML algorithms to study risk factors of all-cause mortality. We evaluated the algorithms using area under the receiver operating curve (AUC-ROC), sensitivity, negative predictive value (NPV) among other metrics and interpreted the results using SHapley Additive exPlanation.

RESULTS

The AUC-ROC ranged from 0.80 ─ 0.87. The super learner had the highest AUC-ROC of 0.87 (95 % CI, 0.86 ─ 0.88), sensitivity of 0.86 (95 % CI, 0.84 ─ 0.88) and NPV of 0.98 (95 % CI, 0.98 ─ 0.99). Key risk factors of mortality included advanced age, larger waist circumference, male and systolic blood pressure. Being married, high annual household income, and high education level were linked with low risk of mortality.

CONCLUSIONS

Machine learning can be used to identify risk factors of mortality, which is critical for individualized targeted interventions in epidemiologic studies.

The effectiveness of the Mediterranean Diet for primary and secondary prevention of cardiovascular disease: An umbrella review

AIMS

This study aimed to review meta-analyses of randomised controlled trials that evaluated the effectiveness of the Mediterranean Diet for the primary and secondary prevention of cardiovascular disease.

METHODS

Five databases (Medline, Embase, Cochrane, CINAHL and ProQuest) were searched from inception to November 2022. Inclusion criteria were: (i) systematic review of randomised controlled studies with metanalysis; (ii) adults ≥18 years from the general population with (secondary prevention) and without (primary prevention) established cardiovascular disease; (iii) Mediterranean Diet compared with another dietary intervention or usual care. Review selection and quality assessment using AMSTAR-2 were completed in duplicate. GRADE was extracted from each review, and results were synthesised narratively.

RESULTS

Eighteen meta-analyses of 238 randomised controlled trials were included, with an 8% overlap of primary studies. Compared to usual care, the Mediterranean Diet was associated with reduced cardiovascular disease mortality (n = 4 reviews, GRADE low certainty; risk ratio range: 0.35 [95% confidence interval: 0.15-0.82] to 0.90 [95% confidence interval: 0.72-1.11]). Non-fatal myocardial infarctions were reduced (n = 4 reviews, risk ratio range: 0.47 [95% confidence interval: 0.28-0.79] to 0.60 [95% confidence interval: 0.44-0.82]) when compared with another active intervention. The methodological quality of most reviews (n = 16/18; 84%) was low or critically low and strength of evidence was generally weak.

CONCLUSIONS

This review showed that the Mediterranean Diet can reduce fatal cardiovascular disease outcome risk by 10%-67% and non-fatal cardiovascular disease outcome risk by 21%-70%. This preventive effect was more significant in studies that included populations with established cardiovascular disease. Better quality reviews are needed.

The Association Between Overall, Healthy, and Unhealthy Plant-Based Diet Index and Risk of Prediabetes and Type 2 Diabetes Mellitus: A Systematic Review and Dose-Response Meta-Analysis of Prospective Studies

CONTEXT

The global incidence of prediabetes and type 2 diabetes mellitus (T2DM) has increased substantially in recent years. Among the established, modifiable lifestyle factors associated with favorable prediabetes and T2DM risk, healthy dietary patterns have attracted considerable attention.

OBJECTIVE

The association between adherence to plant-based dietary pattern indices (PDIs), including the overall PDI (O-PDI), healthy PDI (H-PDI), and unhealthy PDI (U-PDI), and the risk of prediabetes and T2DM was investigated in this study.

DATA SOURCES

A literature search was conducted of the PubMed/Medline, Scopus, and Web of Sciences databases from their inception to February 2024. A systematic review and meta-analysis were conducted using random effects models and dose-response analyses. The Cochran Q test and the I2 statistic were used to evaluate heterogeneity between studies.

DATA EXTRACTION

A total of 16 publications, with data on a total of 721 012 participants, were identified for the meta-analysis.

DATA ANALYSIS

According to a pooled analysis, compared with the lowest category of O-PDI and H-PDI adherence, the highest category was associated with a 14% and 19% reduction in T2DM risk, respectively, for O-PDI (effect size [ES] = 0.86; 95%CI, 0.82-0.90; I2 = 57.7) and H-PDI (ES = 0.81; 95%CI, 0.75-0.88; I2 = 82.6). Greater adherence to U-PDI was significantly associated with an 10% increase in the risk of T2DM (ES = 1.10; 95%CI, 1.04-1.16). Consistent associations were found within the predetermined subgroups. As well, there was a nonlinear inverse association between O-PDI, H-PDI, and T2DM risk. No significant association was found between adherence to O-PDI (ES = 0.87; 95%CI, 0.75-1.01; I2 = 68%), H-PDI (ES = 0.99; 95%CI, 0.87-1.13; I2 = 0.0%), and U-PDI (ES = 1.09; 95%CI, 0.94-1.21; I2 = 22.9%) and risk of prediabetes.

CONCLUSION

These findings underscore the importance of dietary selections within the framework of a plant-based dietary pattern, particularly when incorporating healthful, plant-based foods, which may have potential benefits in reducing the T2DM risk.

Associations of Global Burden of Diseases study-derived dietary scores with mortality and chronic disease risk: a comprehensive analysis from the prospective NutriNet-Santé study

The Global Burden of Diseases (GBD) network has proposed theoretical minimum risk exposure level (TMREL) for leading risk factors associated with diet that minimize the risk of morbimortality from chronic diseases. TMREL can be applied to develop follow-up or evaluation indicators in individual studies. The validity of these scores can be tested by assessing associations with health outcomes in prospective cohorts. In this study conducted within the NutriNet-Santé cohort, four dietary scores (TMREL-Risk Score, TMREL-Probability of adequacy, TMREL-standardized distance, and TMREL dietary score) using different scoring methods were developed, with higher scores reflecting less healthy diets. Associations of these scores with the risk of type 2 diabetes, cancer, cardiovascular diseases (CVD) and mortality were estimated using multivariable Cox proportional hazards models, adjusted for a wide range of covariates. Counterfactual and marginal structural models were used to infer causality. Analyses were conducted in a sample of up to103,324 participants ((78.3% women, mean age of 43.6 years old (y) (SD = 14.6)), followed for a median of 8.47 (IQR = 14.7) years (2009-2024). The association with dietary scores (for 1SD-increase) varied in magnitude for each health outcome. For mortality, HR varied from 1.12 (95%CI = 1.07-1.18, ) to 1.18 (95%CI = 1.12-1.24) for TMREL-Stdis and TMREL-DI, for overall cancer from 1.07 (95%CI = 1.03-1.12) to 1.09 (1.04-1.13) for TMREL-RS and TMREL-PA, for CVD from 1.07 (95%CI = 1.00-1.16) to 1.12 (95%CI = 1.04-1.20) for TMREL-PA and TMREL-RS, and for type 2 diabetes from 1.33 (95%CI = 1.23-1.43) to 1.47 (95%CI = 1.36-1.59) for TMREL-DI and TMREL-PA. Marginal structural Cox models strengthened all associations compared to classical analyses. Standardized survival curves showed clear associations, especially for the risk of cancer and type 2 diabetes. Dietary scores based on GBD TMREL can serve as key indicators for characterizing diet quality in relation to long-term health, and using different scoring systems helped evaluate the robustness of these associations.

Burden of diet-related chronic diseases in Chinese and Japanese adults attributable to dietary risk factors from 1990 to 2021: a systematic analysis of the Global Burden of Disease Study 2021

Background

Chronic diseases are a major cause of death, contributing significantly to the global disease burden. The growing aging population and chronic disease burden in China and Japan have a substantial impact on health outcomes. Dietary factors, as key modifiable elements, are particularly important. Therefore, we aimed to analyze and compare the impact of dietary factors on the burden of chronic diseases in China and Japan and to develop measures to reduce this burden.

Methods

According to the WHO classification of chronic diseases, we selected cardiovascular diseases, neoplasms, and diabetes for analysis. We collected relevant data from the GBD database, described and analyzed the disease burden by age, gender, and year, and created bar and trend charts. We conducted a comparative analysis of the dietary factors influencing these three chronic diseases by generating heatmaps. The joinpoint model was used to analyze the time trends of these three diseases from 1990 to 2021.

Results

From 1990 to 2021, the burden of neoplasms and cardiovascular diseases in China and Japan declined to varying degrees, while the burden of diabetes continued to increase. The main dietary risk factor for neoplasms is a high red meat diet, while for cardiovascular diseases, a high-sodium diet, especially in China. In addition, high meat consumption appears to serve as a protective factor for both Chinese and Japanese populations. Regarding dietary risk factors for diabetes, China is associated with a high red meat diet, whereas Japan is characterized by a high-processed meat diet.

Conclusion

By comparing the burden of chronic diseases related to dietary factors in China and Japan, this study proposes strategies for national healthy diets, such as reducing sodium, processed meat, and red meat intake and increasing whole grains, vegetables, and fruit intake. In addition, attention should be given to the dietary status of the elderly, along with targeted health education initiatives.

Association between NT-proBNP levels and risk of atrial fibrillation: a systematic review and meta-analysis of cohort studies

BACKGROUND AND AIMS

N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a well-established biomarker in clinical practice, particularly for heart failure, but its role in predicting atrial fibrillation (AF) risk is not fully understood. This meta-analysis aimed to evaluate the association between NT-proBNP levels and AF incidence, and to explore the potential of NT-proBNP in enhancing AF risk prediction models.

METHODS

We systematically searched databases (PubMed, Embase, Cochrane Library, Web of Science and Scopus) up to August 2024 for prospective studies that reported associations between baseline NT-proBNP levels and incident AF. HRs or relative risks (RRs) with 95% CIs were pooled using random-effects models.

RESULTS

This analysis included 136 089 participants from 16 cohorts, with 8017 incident AF cases. Elevated NT-proBNP levels were associated with a higher risk of developing AF (top vs bottom quartile, RR=3.84, 95% CI 3.03 to 4.87; per SD increment, RR=1.70, 95% CI 1.54 to 1.88). A significant non-linear dose-response relationship was observed (Pnon-linearity<0.05), and stronger associations were noted in older populations and when serum samples were used. Adding NT-proBNP to traditional AF risk models improved predictive accuracy, suggesting its value in AF risk stratification.

CONCLUSIONS

NT-proBNP levels are strongly associated with an increased risk of AF, particularly in older adults. Incorporating NT-proBNP into risk prediction models may enhance early identification of individuals at risk of AF, with potential implications for population-based screening.

Red Meat Consumption and its Relationship With Cardiovascular Health: A Review of Pathophysiology and Literature

Red meat is the muscle meat of mammals like beef, lamb, and pork that is red due to the abundance of myoglobin pigment and becomes even darker when cooked. The global average per capita consumption of meat and the total amount of meat consumed is rising, and there has been a particularly marked increase in the global consumption of chicken and pork. The consumption of red meat has always been a contentious issue, with data suggesting benefits in terms of nutritional value and at the same time linking its consumption to major health disorders such as endocrine abnormalities, gastrointestinal issues, cancers, and cardiovascular diseases (CVDs). Despite being normalized by major food franchises, red meat consumption may lead to adverse cardiovascular outcomes such as atherosclerosis, ischemic heart disease, stroke, and cardiac failure. Given the evidence that indicates the consumption of red and processed meat as a risk factor for cardiovascular diseases and all-cause mortality, it is important to review the effects of red meat on the risk of cardiovascular diseases.

Beef Consumption and Cardiovascular Disease Risk Factors: A Systematic Review and Meta-analysis of Randomized Controlled Trials

Background

Results from observational studies suggest associations of red meat intake with increased risk of cardiovascular disease (CVD); however, RCTs have not clearly demonstrated a link between red meat consumption and CVD risk factors. Further, the specific effects of beef, the most consumed red meat in the United States, have not been extensively investigated.

Objectives

This study aimed to perform a systematic review and meta-analysis of RCT data evaluating the effects of minimally or unprocessed beef intake on CVD risk factors in adults.

Methods

A search of the literature was conducted using PubMed and CENTRAL databases. RCTs in adults that provided diets with fresh or minimally processed beef were included. Data were extracted, and pooled estimates from random-effects models were expressed as standardized mean differences (SMDs) between the beef intervention and comparator intervention with less or no beef. Sensitivity and subgroup analyses were also performed.

Results

Twenty relevant RCTs that met the criteria were included. Beef intake did not impact blood pressure or most lipoprotein-related variables, including total cholesterol, HDL-cholesterol, triglycerides, non-HDL-cholesterol, apolipoprotein A or B, and VLDL-cholesterol. Beef consumption had a small but significant effect on LDL-cholesterol (0.11; 95% CI: 0.008, 0.20; P = 0.03), corresponding to ∼2.7 mg/dL higher LDL-cholesterol in diets containing more beef than that in low-beef or -o beef comparator diets. Sensitivity analyses show this effect was lost when 1 influential study was removed.

Conclusions

Daily unprocessed beef intake do not significantly affect most blood lipids, apolipoproteins, or blood pressures, except for a small increase in LDL-cholesterol compared with diets with less or no beef. Thus, there may be other factors influencing the association of red meat and beef on CVD risk that deserve further investigation.This study was registered at INPLASY as 202420013.

A Scoping Review of the Causal Pathways and Biological Mechanisms Linking Nutrition Exposures and Health Outcomes

BACKGROUND/AIM

Building on the evidence for multifaceted effects of different nutrients, foods and dietary patterns is a new priority for nutrition science. This review aims to describe the causal pathways and biological mechanisms that elucidate the associations between different nutrition exposures (nutrients, foods and dietary patterns) and health outcomes.

METHODS

A scoping review was conducted in two stages: 1) review of nutrition science textbooks; and 2) a review of reviews of empirical literature using a systematic approach to elucidate causal pathways and biological mechanisms for nutrition exposures and health outcomes. Reviews were eligible for inclusion if they reported biological mechanistic pathways between exposures and outcomes of interest among free-living healthy adults and/or children. Causal pathways within and between the exposures and the outcomes were identified and summarised visually.

RESULTS

A total of seven core textbooks and 1,934 reviews of relevant empirical literature were included. The complexity of the causal pathways and the number of biological mechanisms progressively increases as the nutrition exposure changes from nutrients to foods to dietary patterns. The biological mechanisms demonstrate that associations with beneficial or adverse health outcomes are determined by the contrasting chemical composition and physical structure of the different types and forms of nutrition exposures, and that contextual factors (e.g., food processing) can influence these chemical and physical factors for food and dietary pattern exposures.

CONCLUSION

This review provides models that can guide future research, and has several implications for the generation and interpretation of the nutrition evidence, and its synthesis and translation to inform nutrition guidelines and policies.

How Do School Salad Bars Impact Elementary School Students' Dietary Quality and Energy Intake at Lunch? A Randomized Controlled Plate Waste Investigation

Background: Children's dietary quality is suboptimal, increasing the risk of numerous chronic illnesses. Salad bars (SBs) have potential to enhance children's nutritional intake within the National School Lunch Program (NSLP); yet, empirical support is lacking. To address this gap, we evaluated the impact of school salad bars on dietary quality and energy intake at lunch. Methods: Seven matched elementary school pairs were randomly selected. All schools served pre-portioned fruit and vegetables (F&V) at baseline. Within each pair, one school received an SB. Digital imagery plate waste methods were applied at baseline and 4-6 weeks post salad bar installation to determine intake (20% increments for food, ounces for beverages). Dietary quality (Healthy Eating Index (HEI-2015)) and energy intake (kcal) were evaluated in NDSR. Multilevel modeling evaluated group (SB vs. control) and time (baseline vs. post) differences and group-by-time interactions for: (1) HEI-2015 (total and component scores) and (2) kcal intake (overall, F&V, non-F&V, and beverage kcals). Results: Data from 5674 trays are reported. Significant group-by-time interactions were observed for HEI-2015 total scores and Greens and Beans, Total Fruit, Whole Fruit, Refined Grains, and Added Sugar component scores (p < 0.0001), supporting improved dietary quality in SB schools. SB HEI-2015 scores were 60.1 ± 9.8 at post (+5.3 from baseline; p < 0.0001) compared with 57.2 ± 9.5 in controls (+1.0 from baseline; p = 0.065). Total energy intake significantly increased in SB schools (376 ± 151 kcal (baseline) → 434 ± 176 kcal (post)), driven by F&V energy (+59 kcal), with no change for controls. Discussion: Within the NSLP, SBs improved dietary quality and increased energy intake due to increased F&V intake without replacing other foods. Results can inform school nutrition policies designed to reduce chronic illness risk.

Diet Quality and Past Changes in Food Consumption as Determinants of Intentions to Eat Less Meat and More Plant-Based Foods

This study aimed to examine the relationship between self-reported changes in food consumption over the past 2 years, quality of actual diet, and declared intentions to eat more plant-based foods while reducing meat consumption in the next year. A cross-sectional study using Computer-Assisted Web Interview (CAWI) was conducted on 1003 Polish adults in 2023. The Beliefs and Eating Habits Questionnaire (KomPAN) was used to assess the frequency of consuming various food groups and to calculate diet quality indices. Four distinct segments ("No change", "All products limited", "Changes in meat", and "Less red meat, more other products") were identified using cluster analysis. Logistic regression analysis verified the associations between these clusters, diet quality indices, and intended changes in plant-based food and meat consumption. The study results showed that most pre-existing changes involved reduced red meat intake (52%). The "No change" cluster (47.9%) was represented by more men, people with lower education, and those with a lower overall dietary quality index (DQI). A higher quality diet (as indicated by the DQI) was associated with a greater tendency to increase plant food consumption and reduce meat consumption across the entire group and within each cluster. A better understanding of how changes in food consumption relate to diet quality and intended changes in plant-based food and meat consumption can inform interventions promoting sustainable consumption, considering both nutritional recommendations and environmental requirements.

Qualitative Analysis of a Home-Delivered Produce Prescription Intervention to Improve Food and Nutrition Security

Background/Objective: In total, 17.9% of households with children experienced food insecurity (FI) in 2023. Produce prescription interventions (PRx) are a viable intervention to address FI and improve diet quality. Few studies have explored home-delivered PRxs in children. The objective of this qualitative study is to explore the experience of a novel PRx among families with young children in households at risk of experiencing FI and diet-related chronic disease. Methods: Semi-structured interviews were conducted with caretakers after the completion of a 12-month PRx. Interviews were recorded, transcribed, and analyzed using thematic analysis to identify emergent themes. Univariate descriptive statistics were used to describe baseline demographics. Results: Twenty-five families were enrolled, from which eighteen completed the program and fifteen agreed to participate in an interview. All participants were African American women. The mean age was 30.2 (±6.4) years old, and the median household size was three. Qualitative data analysis revealed three major themes. (1) The produce delivery partially alleviated financial stress, contributing to increased produce consumption patterns; (2) the intervention positively shifted the nutrition- and cooking-related knowledge and behavior of families; and (3) familial and programmatic barriers affected participation and engagement. Conclusions: PRxs are a viable option to support families to lessen the burden of FI from financial hardship and build healthy dietary habits. These insights can inform future PRx program development, delivery, evaluation, and policy or funding decisions. Future research should examine the sustained impact of PRx on healthy eating, health outcomes among caregivers and their children, and the healthcare cost and utilization rates among PRx participants.

The association between dietary patterns and cardiovascular disease risk factors in Iranian adults: a cross-sectional study

BACKGROUND

Dietary patterns are important factors associated with cardiovascular diseases (CVDs). We examined the association between dietary patterns derived from factor analysis and CVD risk factors.

METHODS

In the present cross-sectional study, a total of 3,687 adults (aged 40 to 70 years) with one or more types of CVDs were enrolled as participants. A validated semi-quantitative food-frequency questionnaire was utilized to assess food intakes, and then dietary patterns were extracted by factor analysis. Fasting blood sugar (FBS), lipid profile, anthropometric indices, and blood pressure (BP) were measured. Multivariable-adjusted logistic regression analysis was employed to ascertain the odds ratio (OR) of CVD risk factors associated with posteriori dietary patterns. In this study, healthy and unhealthy dietary patterns were identified.

RESULTS

Adherence to a healthy dietary pattern was associated with a decrease in systolic BP (SBP) (OR = 0.78; 95% confidence interval (CI): 0.62-0.99) and high-density lipoprotein cholesterol (HDL-C) levels (OR = 1.32; 95% CI: 1.06-1.64). Additionally, greater adherence to the unhealthy dietary pattern was positively associated with SBP (OR = 1.43; 95% CI: 1.13-1.80) and diastolic BP (DBP) (OR = 1.33; 95% CI: 1.01-1.76).

CONCLUSIONS

We concluded that greater adherence to an unhealthy dietary pattern was associated with an increase in SBP and DBP. On the other hand, greater adherence to a healthy dietary pattern could be effective in reducing SBP. Further investigation is recommended to validate these findings.

Food group intakes and high-sensitivity C-reactive protein among community-dwelling Japanese adults: a cross-sectional study

OBJECTIVE

Healthy dietary patterns have been linked to lower levels of chronic inflammation. The present study aimed to investigate the associations between food group intakes and high-sensitivity C-reactive protein (hsCRP) among community-dwelling adults.

DESIGN

Cross-sectional.

SETTING

Three areas in Japan (Shiga, Fukuoka, or Kyushu and Okinawa).

PARTICIPANTS

The present analysis included 13 648 participants (5126 males and 8522 females; age range, 35-69 years) who had been enrolled in the baseline survey of the Japan Multi-Institutional Collaborative Cohort Study. Food group intakes were estimated using a FFQ. Multiple linear regression was used to examine associations between the quartiles of each energy-adjusted food group intake and log-transformed hsCRP.

RESULTS

The following concentration ratios of hsCRP after comparing the highest and lowest quartiles of food group intake were significant: in males, 1·12 (95 % CI 1·02, 1·22) for processed meat, 1·13 (95 % CI 1·03, 1·24) for fish and 0·83 (95 % CI 0·76, 0·90) for nuts; in females, 0·89 (95 % CI 0·81, 0·97) for bread, 1·11 (95 % CI 1·03, 1·19) for processed meat, 0·86 (95 % CI 0·80, 0·92) for vegetables, 1·19 (95 % CI 1·11, 1·29) for fruit, 0·90 (95 % CI 0·84, 0·97) for nuts and 0·88 (95 % CI 0·82, 0·95) for green tea.

CONCLUSIONS

Processed meat and nut intakes were associated with higher and lower hsCRP levels, respectively, in both sexes. However, for several food groups, including fish and fruit, previous findings from dietary pattern analyses were not supported by the present analyses at the food group level.

Association of unsweetened and sweetened cereal consumption with all-cause and cause-specific mortality: a large prospective population-based cohort study

Background & aims: Although previous observational studies have suggested an association between whole grain consumption (including breakfast cereals) and a reduced risk of death, no study has explored in detail the association between consumption of cereal with or without added sweeteners and death. We therefore aimed to evaluate the association between unsweetened, sugar-sweetened, and artificially sweetened cereals and all-cause and cause-specific mortality. Methods: We conducted a prospective cohort study of 186 419 UK Biobank participants who met the inclusion criteria for this study. Participants with baseline demographic, lifestyle, dietary, and clinical data were recruited from 2006 to 2010 and followed up until 2023. The intake of unsweetened, sugar-sweetened, or artificially sweetened cereals was estimated through repeated 24 hour dietary recalls. The non-linear relationships between daily dosage of cereal and all-cause, cancer-specific, and cardiovascular disease (CVD)-specific mortality were calculated using a restricted cubic spline curve. Hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause and cause-specific mortality were calculated using Cox regression models. Results: During a median follow-up of 13.6 years, 11 351 all-cause deaths were recorded, including 6176 cancer deaths and 2126 CVD deaths. Cox regression models with restricted cubic splines showed a non-linear association between unsweetened cereals and all-cause and cancer-specific mortality. Compared with non-consumers, consumers of different amounts of unsweetened cereals (0 to 0.5, 0.5 to 1.5, and >1.5 bowls per day) had lower risks of all-cause mortality in the multivariate Cox models, with respective HRs of 0.89 (95%CI: 0.84-0.95), 0.90 (95%CI: 0.86-0.94), and 0.89 (95%CI: 0.82-0.97). However, no association was observed between consumption of sugar or artificially sweetened cereals and the risk of mortality. When cereals were divided into those with or without dried fruit, the findings were consistent with our primary results. Conclusions: Moderate consumption of unsweetened cereals was associated with a reduced risk of all-cause mortality, suggesting caution in consuming cereals with added sugar or artificial sweeteners.

Associations between eating habits and mental health among adolescents in five nordic countries: a cross-sectional survey

BACKGROUND

The role of eating habits in adolescent mental health has become a growing area of interest for researchers and health professionals. Recent studies suggest that healthy eating habits may play a role in the development and management of mental health. However, existing literature is largely based on clinical populations, and comparisons are challenged by sociocultural differences and methodological issues. The aim of the present study was to use nationally representative data based on standardized procedures, to explore associations between adolescents eating habits and mental health, considering the importance of age, gender, socioeconomic factors, and country.

METHODS

The study was based on data from Nordic adolescents (age 11, 13 and 15 years) who participated in the 2017/2018 Health Behavior in School-aged Children (HBSC) study (n = 22384). General linear modelling and multigroup regression analysis were used to examine the relationship between food habits (intake of fruit, vegetables, sweets, soft drinks), meal habits (intake of breakfast and having family meals together), and mental health (life satisfaction and subjective health complaints). The analyses were weighted and adjusted for age, gender, socio-economic status, and country.

RESULTS

Overall, healthier eating habits were associated with better mental health. The strongest associations were found between meal habits (breakfast consumption and having family meals together) and mental health. Gender and country differences were seen, with weaker associations found among Danish boys.

CONCLUSION

Eating habits should be considered when promoting mental health in the adolescent population. While gender differences and cross-country variations exist, even minor enhancements in eating behaviors could yield meaningful benefits.

Higher plant-derived nitrate intake is associated with lower odds of frailty in a cross-sectional study of community-dwelling older women

PURPOSE

Dietary nitrate intake is inversely related to numerous contributors towards frailty, including cardiovascular disease and poor physical function. Whether these findings extend to frailty remain unknown. We investigated if habitual nitrate intake, derived from plants or animal-based foods, was cross-sectionally associated with frailty in women.

METHODS

Community-dwelling older Australian women (n = 1390, mean age 75.1 ± 2.7 years) completed a validated semi-quantitative food frequency questionnaire (FFQ). Nitrate concentrations in food were obtained from international nitrate databases. We adopted the Rockwood frailty index (FI) of cumulative deficits comprising 33 variables across multiple health domains (scored 0 to 1), which predicts increased hospitalisation and mortality risk. A FI ≥ 0.25 indicated frailty. Cross-sectional associations between nitrate intake (total plant and animal nitrate, separately) and frailty were analysed using multivariable-adjusted logistic regression models (including lifestyle factors), as part of restricted cubic splines.

RESULTS

A non-linear inverse relationship was observed between total plant nitrate intake and frailty. Compared to women with the lowest plant nitrate intake (Quartile [Q]1), women with greater intakes in Q2 (OR 0.69 95%CI 0.56-0.84), Q3 (OR 0.67 95%CI 0.50-0.90) and Q4 (OR 0.66 95%CI 0.45-0.98) had lower odds for frailty. A nadir in the inverse association was observed once intakes reached ~ 64 mg/d (median Q2). No relationship was observed between total animal nitrate and frailty.

CONCLUSION

Community-dwelling older women consuming low amounts of plant-derived nitrate were more likely to present with frailty. Consuming at least one daily serving (~ 75 g) of nitrate-rich green leafy vegetables may be beneficial in preventing frailty.

Traditional rural dietary pattern and all-cause mortality in a prospective cohort study of elderly Costa Ricans: the Costa Rican Longevity and Healthy Aging Study (CRELES)

BACKGROUND

Costa Rica is experiencing a fast demographic aging. Healthy diets may help to ameliorate the burden of aging-related conditions.

OBJECTIVE

This study aimed to investigate the association of a traditional dietary pattern and 2 of its major components (beans and rice) with all-cause mortality among elderly Costa Ricans.

METHODS

The Costa Rican Longevity and Healthy Aging Study (CRELES), a prospective cohort study of 2827 elderly Costa Ricans (60+ y at baseline), started in 2004. We used a food frequency questionnaire (FFQ) to assess usual diet. We calculated dietary patterns using principal component analysis. Multivariate energy-adjusted proportional-hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs).

RESULTS

Over a 15-y follow-up, encompassing 24,304 person-years, 1667 deaths occurred. The traditional Costa Rican dietary pattern was more frequent in rural parts of the country, and it was inversely associated with all-cause mortality. Subjects in the fifth quintile of intake had 18% lower all-cause mortality than those in the first quintile (HR: 0.82; 95% CI: 0.69, 0.98; P-trend = 0.01), particularly among males (HR: 0.73; 95% CI: 0.56, 0.95). Bean intake was associated with lower all-cause mortality among all subjects (HR: 0.79; 95% CI: 0.68, 0.91, highest compared with lowest tertile) and in sex-stratified analysis. Rice consumption was inversely associated with all-cause mortality solely among males (HR: 0.75; 95% CI: 0.60, 0.94, highest compared with lowest tertile).

CONCLUSIONS

Our results suggest that a traditional Costa Rican rural dietary pattern is associated with lower all-cause mortality in elderly Costa Ricans. Beans, a major component of this traditional dietary pattern, was also associated with lower all-cause mortality. These findings could have important implications for public health, given the nutritional transition and the reduction of intake of traditional diets in Latin American countries.

Engaging with 'less affluent' communities for food system transformation: a community food researcher model (FoodSEqual project)

The UK food system is distorted by inequalities in access, failing the people most in need, yet it should provide access to safe, nutritious affordable food for all citizens. Dietary patterns are associated with socio-demographic characteristics, with high levels of diet-related disease mortality attributed to poor dietary habits. Disadvantaged UK communities face urgent public health challenges, yet are often treated as powerless recipients of dietary and health initiatives. The need for food system transformation has been illustrated within recent UK government policy drivers and research funding. The Food Systems Equality project is a research consortium that aims to 'co-produce healthy and sustainable food systems for disadvantaged communities'. The project focusses on innovating food products, supply chains and policies, placing communities at the centre of the change. Tackling the above issues requires new ways of working. Creative approaches in food research are known to empower a wider range of individuals to share their 'lived food experience' narratives, building relationships and corroborating co-production philosophies, thus promoting social justice, and challenging more traditional positivist/reductionist 'biomedical' approaches for nutrition and food studies. This review paper critiques the use of community-centric approaches for food system transformation, focusing on one, a community food researcher model() as an exemplar, to highlight their utility in advocating with rather than for less affluent communities. The potential for creative methods to lead to more equitable and lasting solutions for food system transformation is appraised, consolidating the need for community-driven systemic change to foster more progressive and inclusive approaches to strengthen social capital. The paper closes with practice insights and critical considerations offering recommendations for readers, researchers, and practitioners, enabling them to better understand and apply similar approaches.

Low energy intake and nutritional maladaptation in terminal stage IV periodontitis

AIM

Impairment of masticatory function in elderly patients with terminal dentition due to stage IV periodontitis (TDS4P) may lead to lower nutritional intake. The study aimed to report the dietary intake and nutrition status of elderly patients with TDS4P and compare them with those of the elderly Chinese population and the Chinese Dietary Reference Intakes (DRIs).

MATERIALS AND METHODS

Fifty-one consecutive subjects (≥55 years old) with TDS4P were enrolled. Average dietary intake was evaluated based on a 3-day 24-h dietary recall (24HR) and food frequency questionnaire (FFQ). The daily intake of fresh vegetables and fruits, dietary energy as well as macro and micronutrients were calculated and compared with matched national data and the Chinese DRIs. Nutritional status was assessed by Short-Form Mini-Nutritional assessment.

RESULTS

Of the subjects, 19.6% (95% CI: 7.2%-28.1%) were at risk of malnutrition. The mean daily energy intake was 1517.4 kcal (95% CI: 1400.5-1634.3) for males and 1110.7 kcal (95% CI: 1001.5-1219.9) for females, which were very low compared with both the national data and the DRIs. Females derived a higher percentage of energy from fat. The mean daily intake of vegetables was 151.4 g (95% CI: 128.1-174.8) by FFQ and 130.9 g (95% CI: 104.6-157.3) by 24HR. Both results were significantly lower than the national reports (95% CI: 310.3-340.1) and the DRIs (300-450 g). Insufficient micronutrient intake, especially vitamins A, C and E, was also found.

CONCLUSIONS

Elderly subjects with TDS4P had a lower daily energy intake, vegetable and fruit consumption and essential macro and micronutrient intake. More studies are needed to clarify the impact of periodontitis and tooth loss/replacement on nutrition and healthy ageing.

Sex differences in association of healthy eating pattern with all-cause mortality and cardiovascular mortality

BACKGROUND

Although the Healthy Eating Index (HEI) is widely recommended to reduce the risk of cardiovascular disease and all-cause death, there are significant differences in physiological and nutritional factors between the sexes. The potential impact of sex on adult dietary health is still poorly understood. The study was designed to assess whether the health benefits of diet differed by sex.

METHODS

In a prospective study of 39,567 U.S. adults (51.2% female, age 46.8 ± 17.6 years), we examined sex-specific, multivariable-adjusted associations of HEI with all-cause mortality and cardiovascular disease mortality. Restricted cubic splines (RCS), subgroup analysis, propensity score matching (PSM), random forest feature importance, and sensitivity analysis were also used.

RESULTS

During 328,403 person-years of follow-up, a total of 4754 all-cause deaths were recorded, including 1481 cardiovascular deaths. Compared to the lowest quartile of HEI, the all-cause mortality rate of females and males in the highest quartile array decreased by 34% (HR 0.66 [95% CI 0.55-0.8]) and 15% (HR 0.85 [95% CI 0.73-0.99]), respectively. The restricted cubic spline showed a linear inverse association between baseline HEI and all-cause mortality and CVD mortality, with similar sex-specific results. Similarly, component scores were sex-specific for mortality risk, with females benefiting more from diet. The benefits of dairy products, vegetables, and sodium scores on the risk of all-cause death were higher in males and females. However, the benefits of vegetable, sodium, and fatty acid scores on the risk of cardiovascular death were different.

CONCLUSIONS

In the adult population of the U.S., there are more opportunities for females to reduce the risk of all-cause mortality and cardiovascular mortality from the same dose of healthy dietary intake than males. These findings could reduce the risk of death by motivating the population, especially females, to consume healthy dietary components, especially vegetables and dairy products.

Macronutrient composition of plant-based diets and breast cancer risk: the E3N prospective cohort study

PURPOSE

Recent evidence suggests that plant-based diets may reduce the risk of breast cancer (BC). However, the macronutrient composition of plant-based diets and its potential impact on BC risk has not been well explored. This analysis investigated the association of macronutrient composition with BC risk across a spectrum of plant-based diet indexes using a multidimensional approach.

DESIGN

This study followed 64,655 participants from the Etude Epidémiologique auprès de femmes de la Mutuelle Générale de l'Education Nationale (E3N) cohort from 1993 to 2014. Diets were evaluated using validated 208-item diet history questionnaires at baseline (1993) and follow-up (2005), to calculate adherence to the overall plant-based diet (PDI), healthful plant-based diet (hPDI), and unhealthful plant-based diet (uPDI). The association of macronutrient composition with BC risk was assessed via generalized additive time-dependent Cox models across different levels of these indexes. Response surfaces were generated to visualize compositional associations at the 25th, 50th, and 75th percentile of each index (low, moderate, and high).

RESULTS

A total of 3,932 incident BC cases were identified during the 21-year follow-up. There was a significant association between macronutrient composition and BC risk for hPDI, uPDI, and PDI (all P < 0.001). Akaike information criterion favored the hPDI model for characterizing the association between macronutrients and BC. BC risk was highest for individuals with a lower hPDI score who also consumed a diet containing lower protein (10%), lower carbohydrate (35%), and higher fat (55%). The lowest risk of BC was observed in those with higher hPDI scores with the lowest intake of protein (10%). At higher PDI and uPDI, diets containing higher protein (30%) and fat (45%) had the highest BC risk.

CONCLUSION

These results demonstrate a complex relationship between macronutrient composition, plant-based diet quality, and BC risk. Further research is needed to examine specific foods that may be driving these associations.

REGISTRY

The protocol is registered at clinicaltrials.gov as NCT03285230.

Dietary inflammatory potential and arterial stiffness in a French cohort: Insights from the STANISLAS study

BACKGROUND AND AIMS

Chronic inflammation plays a key role in arterial stiffness pathogenesis. Dietary components can display anti- or pro-inflammatory properties. Nonetheless, the association between the diet's overall inflammatory potential and arterial stiffness is unclear. This study aimed to assess the association between the diet's overall inflammatory potential and arterial stiffness assessed by carotid-femoral pulse wave velocity (cfPWV).

METHODS AND RESULTS

This cross-sectional study included 1307 participants from the STANISLAS family cohort study. Dietary data were collected using a validated food frequency questionnaire. The adapted dietary inflammatory index (ADII) score was calculated to assess the inflammatory potential of the participants' diet. The association of ADII score quartile with cfPWV was assessed using IPW-weighted linear mixed models with random family effect. The median (Q1-Q3) ADII score was 0.45 (-1.57, 2.04). Participants exhibiting higher ADII scores demonstrated elevated energy intake, dietary saturated fat, and ultra-processed foods. Conversely, individuals with lower ADII scores exhibited higher vitamins and omega intakes, and a higher diet quality, as assessed by the DASH score. Despite these observations from the descriptive analyses, ADII score quartiles were not significantly associated with cfPWV (β(95% CI) were 0.01 (-0.02,0.04) for Q2, 0.02 (-0.01,0.05) for Q3, and 0.02 (-0.01,0.05) for Q4 compared to Q1).

CONCLUSION

In this cross-sectional study, participants had a relatively modest consumption of pro-inflammatory foods, no substantial associations were observed between the diet inflammatory potential and arterial stiffness. Further longitudinal studies in larger cohorts are needed to better understand the link between inflammatory diet and arterial stiffness.

Life expectancy gains from dietary modifications: a comparative modeling study in 7 countries

BACKGROUND

Eating healthier is associated with a range of favorable health outcomes. Our previous model estimated the impact of dietary changes on life expectancy gains but did not consider height, weight, or physical activity.

OBJECTIVES

We aimed to estimate the increase in life expectancy resulting from the transition from typical national dietary patterns to longevity-optimizing dietary changes, more feasible dietary modifications, and optimized vegan dietary changes in China, France, Germany, Iran, Norway, the United Kingdom, and the United States.

METHODS

Our modeling study used data from meta-analyses presenting dose-response relationships between intake of 15 food groups and mortality. Background mortality data were from the Global Burden of Disease Study. We used national food intake data and adjusted for height, weight, and physical activity level.

RESULTS

For 40-y-olds, estimated life expectancy gains ranged from 6.2 y (with uncertainty interval [UI]: 5.7, 7.5 y) for Chinese females to 9.7 y (UI: 8.1, 11.3 y) for United States males following sustained changes from typical country-specific dietary patterns to longevity-optimized dietary changes, and from 5.2 y (UI: 4.0, 6.5 y) for Chinese females to 8.7 y (UI: 7.1, 10.3 y) for United States males following changes to optimized vegan dietary changes.

CONCLUSIONS

A sustained change from country-specific typical dietary pattern patterns to longevity-optimized dietary changes, more feasible dietary changes, or optimized vegan dietary changes are all projected to result in substantial life expectancy gains across ages and countries. These changes included more whole grains, legumes, and nuts and less red/processed meats and sugars and sugar-sweetened beverages. The largest gains from dietary changes would be in the United States.

Diabetes Risk Reduction Diet (DRRD) and Breast Cancer Risk: A Review

BACKGROUND

Considering the significant involvement of insulin resistance in various forms of cancer, it is postulated that the implementation of a diabetic diet, which effectively mitigates insulin resistance, may potentially decrease the susceptibility to breast cancer among female individuals.

METHODS

In this literature review, a comprehensive electronic search of different databases was done using the keywords "Breast cancer" OR "breast tumor" OR "Breast Neoplasms" AND "diet" OR "diabetic diet" OR "Low Carbohydrate Diet" OR "Carbohydrate restricted diet" OR "High-Protein Low-Carbohydrate Diet" OR "diabetes risk reduction diet" OR "DRRD" as the main keywords.

RESULTS

Research has shown that the DRRD score is inversely correlated with breast cancer risk. In fact, for every three-point increase in the DRRD score, the risk of breast cancer decreases by 7%. Studies have shown that higher DRRD scores in breast cancer patients are associated with a reduced risk of cancer and a higher chance of survival.

CONCLUSION

The results of this study indicate a positive correlation between a higher level of adherence to the diabetes risk reduction diet (DRRD) and improved survival rates. This suggests that breast cancer survivors may benefit from making dietary modifications in line with a diabetic diet following their diagnosis.

Diet, Food, and Nutritional Exposures and Inflammatory Bowel Disease or Progression of Disease: an Umbrella Review

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), contributes to substantial morbidity. Understanding the intricate interplay between dietary factors and the incidence and progression of IBD is essential for developing effective preventative and therapeutic strategies. This umbrella review comprehensively synthesizes evidence from systematic reviews and meta-analyses to evaluate these complex associations. Dietary factors associated with an increased incidence and/or progression of IBD include a high intake of red and processed meat, other processed foods, and refined sugars, together with a low intake of vegetables, fruits, and fiber. For most other food groups, the results are mixed or indicate no clear associations with IBD, CD, and UC. Some differences seem to exist between UC and CD and their risk factors, with increased intake of dietary fiber being inversely associated with CD incidence but not clearly associated with UC. Dietary fiber may contribute to maintaining the gut epithelial barrier and reduce inflammation, often through interactions with the gut microbiota. This seems to play an important role in inflammatory mechanisms in the gut and in IBD incidence and progression. Diets low in fermentable saccharides and polyols can alleviate symptom burden, but there are concerns regarding their impact on the gut microbiota and their nutritional adequacy. Mediterranean diets, vegetarian diets, and a diet low in grains, sugars, and lactose (specific carbohydrate diet) are also associated with lower incidence and/or progression of IBD. The associations of dietary patterns are mirrored by inflammatory biomarkers. IBD is typically treated pharmaceutically; however, many patients have a suboptimal response to medical treatments. The findings from this umbrella review could provide evidence for nutritional counseling and be a valuable addition to traditional treatment plans for IBD. This systematic review was registered at PROSPERO as CRD440252.

Substitution of Dairy Products and Risk of Death and Cardiometabolic Diseases: A Systematic Review and Meta-Analysis of Prospective Studies

Substitution models in epidemiologic studies specifying both substitute and substituted food in relation to disease risk may be useful to inform dietary guidelines. A systematic review of prospective observational studies was performed to quantify the risks of all-cause mortality, cardiovascular disease, and type 2 diabetes (T2D) associated with the substitution of dairy products with other foods and between different dairy products. We systematically searched MEDLINE, Embase, and Web of Science until 28th June, 2023. We calculated summary relative risks (SRRs) and 95% confidence intervals (95% CI) in random-effects meta-analyses. We assessed the risk of bias with the Risk Of Bias In Non-randomized Studies - of Exposure (ROBINS-E) tool and certainty of evidence (CoE) using the Grading of Recommendations Assessment, Development, and Evaluations (GRADE) approach. Fifteen studies (with 34 publications) were included. There was moderate CoE that the substitution of low-fat dairy with red meat was associated with a higher risk of mortality, coronary artery disease, and T2D [SRR (95% CI): 1.11 (1.06, 1.16), 1.13 (1.08, 1.18), and 1.20 (1.16, 1.25)]. A higher risk of mortality and T2D was also observed when substituting low-fat dairy with processed meat [SRR (95% CI): 1.19 (1.11, 1.28) and 1.41 (1.33, 1.49); moderate CoE]. A lower mortality risk was associated with the substitution of dairy and yogurt with whole grains [SRR (95% CI): 0.89 (0.84, 0.93) and 0.91 (0.85, 0.97)], and butter with olive oil [SRR (95% CI): 0.94 (0.92, 0.97); all moderate CoE]. Mainly no associations were observed when substituting dairy products against each other on disease and mortality risk. Our findings indicate associations between substituting dairy with red or processed meat and higher disease risk, whereas its substitution with whole grains was associated with a lower risk. However, there is little robust evidence that substituting whole-fat with low-fat dairy is associated with disease risk. (CRD42022303198).

Perspective: Beyond the Mediterranean Diet-Exploring Latin American, Asian, and African Heritage Diets as Cultural Models of Healthy Eating

The Mediterranean diet is a well-studied cultural model of healthy eating, yet research on healthy models from other cultures and cuisines has been limited. This perspective article summarizes the components of traditional Latin American, Asian, and African heritage diets, their association with diet quality and markers of health, and implications for nutrition programs and policy. Though these diets differ in specific foods and flavors, we present a common thread that emphasizes healthful plant foods and that is consistent with high dietary quality and low rates of major causes of disability and deaths. In this perspective, we propose that nutrition interventions that incorporate these cultural models of healthy eating show promise, though further research is needed to determine health outcomes and best practices for implementation.

Health Promotion and Chronic Disease Prevention at the Workplace

The concept of workplace safety and health has focused largely on preventing accidents and on minimizing hazardous exposures. However, because workers spend a substantial part of their waking hours at the workplace, the potential to influence the health of a large proportion of the world's population through the workplace is enormous. The opportunities to carry out health promotion and chronic disease prevention activities at the workplace are countless, including (a) health screening; (b) tobacco cessation activities; (c) the promotion of healthy food choices and weight loss; (d) active breaks with physical exercise in terms of microexercise, enhancement of infrastructure to stimulate physical activity, and organization of work tasks to facilitate incidental physical activity; and (e) routine vaccinations. This review discusses the key factors necessary to implement health promotion and chronic disease prevention programs at the workplace (SWOLE model) and discusses the different foci and possibilities with respect to the differing nature of work for the blue- versus white-collar workforce.

Plant-based diets, mediating biomarkers, and mortality risk among adults with diabetes or prediabetes

Background: A healthy eating pattern characterized by a higher intake of healthy plant foods has been associated with a lower risk of premature mortality, but whether this applies to individuals with varying glycemic status remains unclear. Methods: This study included 4621 participants with diabetes and 8061 participants with prediabetes from the US National Health and Nutrition Examination Survey (2007-2016). Using the dietary data assessed by two 24 h dietary recalls, a healthful plant-based diet index (hPDI) and an unhealthful plant-based diet index (uPDI) were created based on 15 food groups and were assessed for their relationships with mortality risk. Results: Over a median follow-up of 7.2 years, there were 1021 deaths in diabetes and 896 deaths in prediabetes. A higher hPDI (highest vs. lowest quartile) was associated with a 41% (HR = 0.59, 95% CI: 0.49-0.72; P-trend < 0.001) lower risk of all-cause mortality in diabetes and a 31% (HR = 0.69, 95% CI: 0.55-0.85; P-trend < 0.001) lower risk in prediabetes. A higher uPDI was associated with an 88% (HR = 1.88, 95% CI: 1.55-2.28; P-trend < 0.001) higher risk of mortality in diabetes and a 63% (HR = 1.63, 95% CI: 1.33-1.99; P-trend < 0.001) higher risk in prediabetes. Mediation analysis suggested that C-reactive protein and γ-glutamine transaminase explained 6.0% to 10.9% of the relationships between hPDI or uPDI and all-cause mortality among participants with diabetes. Conclusions: For adults with diabetes as well as those with prediabetes, adhering to a plant-based diet rich in healthier plant foods is associated with a lower mortality risk, whereas a diet that incorporates less healthy plant foods is associated with a higher mortality risk.

Association of Cantonese dietary patterns with mortality risk in older Chinese: a 16-year follow-up of a Guangzhou Biobank cohort study

Background: Evidence about the associations between Cantonese dietary patterns and mortality is scarce. We examined the prospective association of the dietary pattern with all-cause, cancer and cardiovascular disease (CVD) mortality in older Chinese. Methods: We included 19 598 participants of a Guangzhou Biobank cohort study aged 50+ years, who were recruited from 2003 to 2006 and followed up until July, 2022. The diet was assessed by using a 300-item validated food frequency questionnaire. The food items were collapsed into 27 food groups. Factor analysis (FA) was used to identify dietary patterns. Multivariable Cox regression produced hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality. Results: During 305 410 person-years, 4966 deaths including 1971 CVD, 1565 cancer and 1436 other-causes occurred. Four dietary patterns were identified by FA. No association of the vegetable-based dietary pattern with all-cause, CVD and cancer mortality was found. Compared with the lowest quartile of the healthy Cantonese dietary pattern score, the highest quartile showed lower risks of all-cause (HR 0.86, 95% CI 0.80-0.94) and CVD mortality (HR 0.84, 95% CI 0.72-0.97). The highest quartile of the nut and fruit dietary pattern showed lower risks of all-cause (HR 0.92, 95% CI 0.85-0.99) and CVD mortality (HR 0.82, 95% CI 0.72-0.93), while the unhealthy western dietary pattern was associated with a higher risk of all-cause (HR 1.10, 95% CI 1.01-1.19) and cerebrovascular disease mortality (HR 1.28, 95% CI 1.03-1.58). Conclusion: We have first identified four dietary patterns based on the Cantonese cuisine and found that healthy Cantonese and nut and fruit dietary patterns were associated with lower risks of all-cause and CVD mortality, whereas the unhealthy western dietary pattern was associated with a higher risk of all-cause and cerebrovascular disease mortality.

Association of a Mediterranean Lifestyle With All-Cause and Cause-Specific Mortality: A Prospective Study from the UK Biobank

OBJECTIVE

To examine the association between the Mediterranean lifestyle and all-cause, cancer, and cardiovascular disease (CVD) mortality in a British population.

PATIENTS AND METHODS

We studied 110,799 individuals 40 to 75 years of age from the UK Biobank cohort, free of CVD or cancer between 2009 and 2012 who were followed-up to 2021. The Mediterranean lifestyle was assessed at baseline through the Mediterranean Lifestyle (MEDLIFE) index, derived from the lifestyle questionnaire and diet assessments and comprising three blocks: (1) "Mediterranean food consumption," (2) "Mediterranean dietary habits," and (3) "physical activity, rest, social habits, and conviviality." Death information was retrieved from death register records. Cox regression models were used to analyze the study associations.

RESULTS

During a median 9.4-year follow-up, 4247 total deaths, 2401 cancer deaths, and 731 CVD deaths were identified. Compared with the first quartile of the MEDLIFE index, increasing quartiles had HRs of 0.89 (95% CI, 0.81 to 0.97), 0.81 (95% CI, 0.74 to 0.89), and 0.71 (95% CI, 0.65 to 0.78) (P-trend<.001 for all-cause mortality). For cancer mortality, the quartiles had HRs of 0.90 (95% CI, 0.80 to 1.01), 0.83 (95% CI, 0.74 to 0.93), and 0.72 (95% CI, 0.64 to 0.82) (P-trend<.001). All MEDLIFE index blocks were independently associated with lower risk of all-cause and cancer death, and block 3 was associated with lower CVD mortality.

CONCLUSION

Higher adherence to the Mediterranean lifestyle was associated with lower all-cause and cancer mortality in British middle-aged and older adults in a dose-response manner. Adopting a Mediterranean lifestyle adapted to the local characteristics of non-Mediterranean populations may be possible and part of a healthy lifestyle.

Serum apolipoproteins and mortality risk: evidence from observational and Mendelian randomization analyses

BACKGROUND

Apolipoproteins (APOs) have emerged as significant players in lipid metabolism that affects the risk of chronic disease. However, the impact of circulating APO concentrations on premature death remains undetermined.

OBJECTIVES

This study aimed to investigate the associations of serum APOs with all-cause, cardiovascular disease (CVD)-related, and cancer-related mortality.

METHODS

We included 340,737 participants who had serum APO measurements from the UK Biobank. Restricted cubic splines and multivariable Cox regression models were used to assess the associations between APOs and all-cause and cause-specific mortality by computing hazard ratios (HRs) and 95% confidence intervals (CIs). Based on 1-sample Mendelian randomization (MR) design, including 398,457 participants of White ancestry who had genotyping data from the UK Biobank, we performed instrumental variable analysis with 2-stage least squares regression to assess the association between genetically predicted APOs and mortality.

RESULTS

After adjusting for potential confounders including high-density and low-density lipoprotein particles, we observed nonlinear inverse relationships of APOA1 with all-cause, CVD-related, and cancer-related mortality (P-nonlinear < 0.001). By contrast, positive relationships were observed for APOB and all-cause (P-nonlinear < 0.001), CVD-related (P-linear < 0.001), and cancer-related (P-linear = 0.03) mortality. MR analysis showed consistent results, except that the association between APOB and cancer mortality was null. Furthermore, both observational and MR analyses found an inverse association between APOA1 and lung cancer-related mortality (HR comparing extreme deciles: 0.46; 95% CI: 0.26, 0.80; and HR: 0.78; 95% CI: 0.63, 0.97, respectively).

CONCLUSIONS

Our findings indicate that circulating APOA1 has potential beneficial effects on all-cause, CVD-related, and lung cancer-related death risk, whereas APOB may confer detrimental effects on all-cause and CVD-related death risk.

Dietary patterns associated with hypertension among stroke-free indigenous Africans: insights from the Stroke Investigative Research and Educational Network study

BACKGROUND

The dietary factors associated with the high burden of hypertension among indigenous Africans remain poorly understood. We assessed the relationship between dietary patterns and hypertension among indigenous Africans.

METHOD

In this study, 1550 participants with hypertension matched (for age: ± 5 years, sex and ethnicity) with 1550 participants without hypertension were identified from the stroke-free population in the Stroke Investigative Research and Educational Network study in Ghana and Nigeria. Food consumption was assessed using a food frequency questionnaire, and dietary information was summarized using principal component analysis to identify seven dietary patterns. Conditional logistic regression was applied to compute the odds ratio (OR) and 95% confidence interval (CI) for the risk of hypertension by tertiles of dietary patterns adjusting for age, education, income, smoking, alcohol use, physical inactivity, family history of cardiovascular diseases, obesity and salt intake at a two-sided P less than 0.05.

RESULTS

Multivariable-adjusted OR [95% confidence interval (CI)] for risk of hypertension by second and third tertiles [using the lowest (first) tertile as reference] of dietary patterns were 0.62 (0.48-0.80), 0.70 (0.54-0.90) for whole grains and fruit drinks; 0.87 (0.68-1.12), 0.83 (0.64-1.08) for fruits; 0.85 (0.65-1.10), 0.97 (0.75-1.26) for vegetables, legumes and potatoes; 0.78 (0.60-1.00), 0.84 (0.65-1.08) for fried foods and sweetened drinks; 1.13 (0.88-1.45), 0.80 (0.62-1.03) for poultry product and organ meat; 1.11 (0.86-1.43), 0.88 (0.68-1.14) for red meat; and 1.14 (0.88-1.48), 1.09 (0.84-1.43) for processed foods ( P  < 0.05).

CONCLUSION

A higher adherence to dietary consumption of whole grains and fruits was inversely associated with low odds of hypertension in this population.

Legumes and pulses - a scoping review for Nordic Nutrition Recommendations 2023

Consumption of legumes and pulses is associated with various health outcomes. Therefore, when updating the Nordic Nutrition Recommendations (NNR), summarizing the best available evidence on key health outcomes regarded as relevant for the Nordic and Baltics related to the consumption of legumes was essential. The aim of this scoping review was to evaluate the updated evidence on the effect of the consumption of legumes and pulses on various health outcomes, as well as their dose-response relationship in updated systematic reviews and meta-analyses. The scoping review is built on a de novo systematic review published in 2023 and additional searches on the consumption of legumes and pulses and its various health outcomes, including cardiovascular disease (CVD), cancer, type 2 diabetes, and obesity. Current available evidence shows that the consumption of legumes and pulses is associated with a lower risk of several cancers (evidence: low-moderate), and lower all-cause mortality (evidence: moderate). The associations with CVDs are neutral or inverse, with studies generally showing favourable changes in biomarkers for CVDs. Legume consumption is associated with a lower risk of obesity (evidence: low). For type 2 diabetes, no association was found with incidence, but trials on consumption of legumes and pulses and biomarkers generally indicated protective effects. Overall, the current evidence supports dietary recommendations to increase the consumption of legumes and pulses.
