Combined effects of fruit and vegetables intake and physical activity on the risk of metabolic syndrome among Chinese adults

Plant bioactive compounds from Mediterranean diet improve risk factors for metabolic syndrome

Mediterranean (Med) dietary pattern consists of moderate or high consumption of foods that are linked to reduced risk factors for metabolic syndrome (MetS). This comprehensive review evaluates studies on Med diet-representative foods and beverages, such as red wine and olive oil, to understand the inverse associations of Med diet and MetS. The intake of dietary fibre, unsaturated fatty acids, vitamins, and polyphenols - including flavonoids and stilbenes - help to explain the benefits of Med diet on abdominal adiposity, glucose intolerance, hyperlipidaemia, and high blood pressure to some extent. Antioxidant and anti-inflammatory properties of polyphenols as well as the effects of unsaturated fatty acids on lipid metabolism are part of the underlying mechanisms. Overall, this review shows that dietary interventions using Med diet components improve MetS health markers in humans and/or rodents.

Global Impacts of Western Diet and Its Effects on Metabolism and Health: A Narrative Review

The Western diet is a modern dietary pattern characterized by high intakes of pre-packaged foods, refined grains, red meat, processed meat, high-sugar drinks, candy, sweets, fried foods, conventionally raised animal products, high-fat dairy products, and high-fructose products. The present review aims to describe the effect of the Western pattern diet on the metabolism, inflammation, and antioxidant status; the impact on gut microbiota and mitochondrial fitness; the effect of on cardiovascular health, mental health, and cancer; and the sanitary cost of the Western diet. To achieve this goal, a consensus critical review was conducted using primary sources, such as scientific articles, and secondary sources, including bibliographic indexes, databases, and web pages. Scopus, Embase, Science Direct, Sports Discuss, ResearchGate, and the Web of Science were used to complete the assignment. MeSH-compliant keywords such "Western diet", "inflammation", "metabolic health", "metabolic fitness", "heart disease", "cancer", "oxidative stress", "mental health", and "metabolism" were used. The following exclusion criteria were applied: (i) studies with inappropriate or irrelevant topics, not germane to the review's primary focus; (ii) Ph.D. dissertations, proceedings of conferences, and unpublished studies. This information will allow for a better comprehension of this nutritional behavior and its effect on an individual's metabolism and health, as well as the impact on national sanitary systems. Finally, practical applications derived from this information are made.

Sociodemographic and lifestyle factors and the risk of metabolic syndrome in taxi drivers: A focus on street food

Background

In South Africa, similar to other populous countries, the taxi industry is an important form of transportation that contributes to the country's development. As a result, minibus taxi driving is an occupation characterized by strenuous activities such as long hours of driving, limited rest, and challenges related to securing passengers, among several others. Consequently, to combat stress, some commercial drivers resort to smoking, overeating unhealthy food sold at transportation interchange areas (i.e., taxi ranks), and participating in sedentary behaviors. Most of these activities are risk factors for metabolic syndrome (MetS).

Aim

Therefore, this study aimed to investigate the sociodemographic and lifestyle factors that predispose South African taxi drivers who work in the Cape Town Metropole area to the risk of developing MetS.

Methods

This cross-sectional study used a convenient sampling method that included 185 male minibus taxi drivers aged 20 years or above. The participants were interviewed using a validated questionnaire to gather information regarding their sociodemographic characteristics and lifestyle practices. They also underwent physical and metabolic assessments, and the International Diabetes Federation (IDF) criteria were used to diagnose people with MetS.

Results

Overall, the mean age and driving experience of the taxi drivers were 40.0 years (SD: 10.7) and 9.1 years (SD: 7.4), respectively, with those with MetS being significantly older and having more driving experience than those without. Older participants were 3 and 2.9 times more likely to be diagnosed with MetS than the younger participants. Most taxi drivers (70%) met the IDF diagnostic criteria for MetS. Smokers, those who spent more than 100 ZAR (USD 5.9) and those who spent less than 1.4 MET-minutes per week on physical activity were 1.96, 2.0, and 13.6 times more likely to suffer from MetS that those who were nonsmokers, those who spent less than 100 ZAR and those who spent <1.4 MET-minutes per week on physical activity. Consumption of alcohol and sugar-sweetened beverages (SSBs), as well as takeaway and fried foods, snacks, and sold by the SF vendors, increased the likelihood of developing MetS, abnormal HDL-C, TG, and hypertension, while avoiding takeaway and fried foods decreased this likelihood. Taxi drivers who also avoided consuming fresh fruits had abnormal HDL-C.

Conclusion

These findings have significant public health implications, highlighting the need for South African policymakers to adopt a system-level approach to promote lifestyle changes among taxi drivers within the taxi industry. This can help reduce the health risks faced by these drivers and improve their overall health profile.

Hydroethanolic Extract of Prunus domestica L.: Metabolite Profiling and In Vitro Modulation of Molecular Mechanisms Associated to Cardiometabolic Diseases

High consumption of fruit and vegetables has an inverse association with cardiometabolic risk factors. This study aimed to chemically characterize the hydroethanolic extract of P. domestica subsp. syriaca fruit pulp and evaluate its inhibitory activity against metabolic enzymes and production of proinflammatory mediators. Ultra-high-performance liquid chromatography high-resolution mass spectrometry(UHPLC-HRMS) analysis showed the presence of hydroxycinnamic acids, flavanols, and glycoside flavonols, while nuclear magnetic resonance(NMR) analysis showed, among saccharides, an abundant presence of glucose. P. domestica fruit extract inhibited α-amylase, α-glucosidase, pancreatic lipase, and HMG CoA reductase enzyme activities, with IC50 values of 7.01 mg/mL, 6.4 mg/mL, 6.0 mg/mL, and 2.5 mg/mL, respectively. P. domestica fruit extract inhibited lipopolysaccharide-induced production of nitrite, interleukin-1 β and PGE₂ in activated J774 macrophages. The findings of the present study indicate that P. domestica fruit extracts positively modulate in vitro a series of molecular mechanisms involved in the pathophysiology of cardiometabolic diseases. Further research is necessary to better characterize these properties and their potential application for human health.

Associations of fruit & vegetable intake and physical activity with poor self-rated health among Chinese older adults

BACKGROUND

Despite the existing literature highlights the central roles of sociodemographic factors, fruit & vegetable (F&V) intake, and physical activities for maintaining good health, less is known about the associations in the Chinese context. This study attempted to explore the associations of servings of F&V intake and levels of physical activities with poor self-rated health (SRH) among Chinese older adults.

METHODS

Data were drawn from the Study on Global Ageing and Adult Health-China (SAGE-China) issued by the World Health Organization and included 7560 respondents aged ≥60 years in China. After screening out the potential confounding factors, multiple logistic regression models were adopted to explore the associations of sociodemographic factors, servings of F&V intake, and levels of physical activities with poor SRH.

RESULTS

Among the sample, nearly a quarter reported poor health status. There were significant gender differences in the case of servings of F&V intake and levels of physical activities. Logistic regressions indicated that higher fruit intake was associated with lower likelihood of vigorous level of physical activity as compared to zero intake. Likewise, higher vegetable intake (≥10 servings) was associated with a higher likelihood of vigorous & moderate level of physical activity when compared to lower intake (≤ 4 servings). Higher fruit intake was associated with a lower likelihood of poor SRH. Similarly, vegetable intake (5 servings: AOR = 0.69, 95%CI: 0.58-0.83; 6-9 servings: AOR = 0.72, 95%CI: 0.59-0.87) was significantly associated with poor SRH. Additionally, vigorous level of physical activity (AOR = 0.79, 95%CI: 0.65-0.97) and vigorous fitness/leisure (AOR = 0.57, 95%CI: 0.39-0.84) were significantly associated with poor SRH.

CONCLUSION

This study suggested that older adults with high fruit intake had lower probability of performing vigorous & moderate level of physical activity, while those with high vegetable intake had higher probability of performing vigorous & moderate level of physical activity. Likewise, the older adults with high F&V intake and higher probability of performing vigorous level of physical activity, walk/bike activity, and vigorous/moderate fitness/leisure had less likelihood to face the risk for poor SRH outcomes. The appropriate servings of F&V intake and levels of physical activity should be highlighted.

National trends in metabolic syndrome among adults in Mongolia from three cross-sectional surveys in 2009, 2013 and 2019

BACKGROUND AND AIM

Metabolic syndrome (MetS) may increase the risk of cardiometabolic diseases. The study aimed to estimate the proportion and associated factors of MetS among individuals (≥15 years) across three cross-sectional surveys in 2009, 2013 and 2019 in Mongolia.

METHOD

Cross-sectional data were analysed from 6,321 individuals (15-64/69 years, median age = 42 years) that participated in the 2009, 2013 or 2019 Mongolia STEPS surveys, and had complete MetS (harmonized definition) measurements.

RESULTS

Almost two in five participants (35.6%) had MetS, 33.3% in 2009, 35.3% in 2013, ad 37.0% in 2019 (p-for trend 0.023). In adjusted logistic regression analyses, older age was associated with MetS in 2009 and in 2019, male sex and higher education were associated with MetS in 2013, and urban residence was associated with MetS in 2009. Current tobacco use was associated with MetS in 2009 and 2019, moderate or high physical activity was protective against MetS in 2013 and 2019, while general overweight and obesity increased the odds of MetS in 2009, 2013, and 2019.

CONCLUSION

The study showed that almost two in five adults were identified as having MetS, which significantly increased from 2009 to 2019, and that several predictors of MetS were found.

Lack of association between nuts and legumes consumption and metabolic syndrome in young Iranian nurses

BACKGROUND

Most studies have investigated the association between dietary pattern and risk of metabolic syndrome. Limited studies have examined the association between nuts and legumes as a food group and metabolic syndrome. This study explored the association between nuts and legumes and components of metabolic syndrome in Iranian nurses.

METHODS

This cross-sectional study included a representative sample of 420 female nurses of Isfahan who were randomly selected. Nuts and legumes consumption was assessed using a validated dish-based semi quantitative food frequency questionnaire (FFQ). Metabolic syndrome was defined by the National Cholesterol Education Program's Adult Treatment Panel III (ATP III). Linear and logistic regression tests were used to study the association between nuts and legumes consumption and metabolic syndrome and its components.

RESULTS

Mean age of study participants was 35 years. The prevalence of the metabolic syndrome among study participants was 3.6%. Consumption of nuts and legumes was not associated with waist circumference either before (β = -0.01, P = 0.24) or after adjusting for potential confounders (β = -0.18, P = 0.41). The same findings were also observed for diastolic blood pressure (DBP) (β = 0.001, P = 0.42), serum triglyceride (TG) (β = 0.07, P = 0.32), high-density lipoprotein cholesterol (HDL-C) (β = 0.008, P = 0.65) and fasting blood sugar (FBS) (β = -0.001, P = 0.94). We failed to find a significant association between consumption of nuts and legumes and systolic blood pressure (SBP) after adjusting for confounders (β = 0.002, P = 0.38). Individuals in the highest category of nuts and legume consumption did not had elevated odds for metabolic syndrome after adjusting for potential confounders (OR = 0.89, 95% CI = 0.08-9.80, P = 0.93).

CONCLUSIONS

Nuts and legumes consumption was not associated with metabolic syndrome or its components. Prospective studies are needed to investigate further this association.

Associations of sleep duration and fruit and vegetable intake with the risk of metabolic syndrome in Chinese adults

To understand the adverse association of short sleep duration and insufficient fruit and vegetable intake (FVI) with and their combined effect on metabolic syndrome (MetS) in Chinese adults.This cross-sectional study analyzed 7052 adults aged 18∼64 years old in 2009, with fasting blood samples collected. Participants were divided into short/normal/long sleep duration groups and sufficient/insufficient FVI groups in accordance with self-reported information. Metabolic syndrome was defined by National Cholesterol Education Program's Adult Treatment Panel III criteria.The prevalence of MetS among the study subjects was 21.74%. Participants were classified into short (<7 h/d), normal (7∼9 h/d), and long (>9 h/d) groups according to their daily sleep duration. Participants with less than 500 g of FVI per day was considered as insufficient FVI. After adjusting for confounders, the negative effect of short sleep duration on MetS was statistically significant, with an OR of 1.29 (95%CI = 1.06∼1.56); and high fasting glucose levels were significantly associated with insufficient FVI. Compared with subjects with normal sleep duration and sufficient FVI, participants with short sleep time and insufficient FVI had the highest risk of MetS (OR = 1.37, 95% CI: 1.04-1.66).This study revealed that insufficient FVI and short sleep duration were significantly associated with an increased risk of MetS among Chinese adults. Increasing FVI and normal sleep duration during Chinese adults could be significant targets for reducing the prevalence of MetS.

Mothers' Perceptions and Attitudes towards Children's Vegetable Consumption-A Qualitative, Cross-cultural Study of Chilean, Chinese and American Mothers Living in Northern California

This exploratory research focused on the cultural variables involved in children’s vegetable consumption, through the analysis of mothers’ perceptions, attitudes, and feeding practices regarding their children’s intake, using qualitative consumer research methods. Twelve focus groups of mothers with children between 2–12 years old (Euro-Americans n = 20, Chinese n = 19, and Chilean n = 19) were conducted. All participants lived in Northern California, had higher education, and incomes that did not limit their vegetable purchase. Intercultural differences in vegetable preferences and consumption habits were found. Mothers across all groups agreed on the importance of children’s vegetable consumption, the influence that mothers have over their children’s vegetable intake, and how challenging it is to get children to eat a variety of vegetables. The ethnic groups differed regarding how they perceived the level of mothers’ responsibility over children’s vegetable intake, the way that mothers defined the amount of vegetables that children should eat, the constraints that mothers had on increasing their children’s vegetable intake and mothers’ recommendations to encourage vegetable consumption. Our study suggests that under similar socio-economic and parental education levels, culture-specific strategies should be considered to foster healthy dietary habits in children.

Fruit and Vegetable Intake and All-Cause Mortality in a Chinese Population: The China Health and Nutrition Survey

This study was to investigate the association of long-term fruit and vegetable (FV) intake with all-cause mortality. We utilized data from the China Health and Nutrition Survey (CHNS), a prospective cohort study conducted in China. The sample population included 19,542 adult respondents with complete mortality data up to 31 December 2011. Cumulative FV intake was assessed by 3 day 24 h dietary recalls. Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of all-cause mortality. Covariates included sociodemographic characteristics, lifestyle factors, health-related factors, and urban index. A total of 1409 deaths were observed during follow-up (median: 14 years). In the fully adjusted model, vegetable intake of the fourth quintile (327~408 g/day) had the greatest negative association with death compared to the lowest quintile (HR = 0.63, 95% CI: 0.53-0.76). Fruit intake of the fifth quintile (more than 126 g/day) had the highest negative association (HR = 0.24, 95% CI: 0.15-0.40) and increasing general FV intake were also negatively associated with all-cause mortality which demonstrated the greatest negative association in the amount of fourth quintile (HR = 0.59, 95% CI: 0.49-0.70) compared to the lowest quintile. To conclude, greater FV intake is associated with a reduced risk of total mortality for Chinese adults. High intake of fruit has a stronger negative association with mortality than differences in intake of vegetables. Our findings support recommendations to increase the intake of FV to promote overall longevity.

Gender-Specific Independent and Combined Effects of the Progesterone and 17-Hydroxyprogesterone on Metabolic Syndrome: From the Henan Rural Cohort Study

BACKGROUND

Although the concentrations of progesterone (P4) and 17-hydroxyprogesterone (17-OHP) have been correlated with some characteristics of metabolic syndrome (MetS), the relationships with MetS are inconclusive. Therefore, we investigated the relationship between P4 and 17-OHP with MetS.

METHODS

In all, the present study includes 4807 participants. Serum P4 and 17-OHP were measured through liquid chromatography-tandem mass spectrometry. Logistic regression and restricted cubic splines were used to assess the independent and combined effects of P4 and 17-OHP on MetS.

RESULTS

After adjusting for multiple variables, the positive association of P4 with MetS was observed in postmenopausal women (Third tertiles vs First tertiles: OR = 1.49, 95% CI: 1.20-1.86) and the negative association of 17-OHP with MetS was observed in men (Third tertiles vs First tertiles: OR = 0.43, 95% CI: 0.32-0.58). Compared with the combination of low P4 and low 17-OHP, the combination of high P4 and high 17-OHP were significantly related to MetS in postmenopausal women (OR = 1.71, 95% CI: 1.18-2.48). Moreover, the combination of low P4 and high 17-OHP was negatively associated with MetS in men (OR = 0.41, 95% CI: 0.24-0.69).

CONCLUSION

The association between P4 and MetS in postmenopausal women was positive, whereas 17-OHP was negatively associated with MetS in men. Additionally, their combination has a synergistic effect on MetS in postmenopausal women and an antagonistic effect on MetS in men.

Association between alcohol consumption and metabolic syndrome among Chinese adults

OBJECTIVE

To assess the prevalence of metabolic syndrome (MetS) in Chinese adults living in Ningbo and to examine the association between alcohol consumption and MetS and its medical components.

DESIGN

A representative survey in Ningbo was conducted in 2015 covering socio-demography. A FFQ together with additional questionnaires was used to collect information on alcohol consumption, diet, demography, lifestyle and medical information. Multivariable logistic regression and generalised linear models were used to examine the association between alcohol consumption and both MetS and its medical components, respectively.

SETTING

Ningbo, China.

PARTICIPANTS

A total of 2853 adults ≥ 20 years (44 % men) in this final analysis.

RESULTS

The prevalence of frequent alcohol drinkers and MetS was 29·9 % and 28·0 %, respectively. Significantly higher prevalence of MetS and mean values of medical components were found in the group of frequent alcohol drinkers with an exception for HDL-cholesterol, compared with less or non-alcohol drinkers. Frequent alcohol consumption was associated with higher odds of developing MetS and positively associated with medical components excepting waist circumference.

CONCLUSIONS

Frequent alcohol consumption contributed to a higher prevalence of MetS and unfavourable influence on MetS and its medical components among Chinese adults. A public health intervention on alcohol restriction is necessary for the prevention and control of the ongoing epidemic MetS.

Association of dietary patterns and practices on metabolic syndrome in adults with central obesity attending a mission hospital in Kenya: a cross-sectional study

OBJECTIVE

Dietary patterns and practices can predispose or protect against metabolic syndrome (MetS) in humans. Despite the growing problem of MetS in adults, the underpinning dietary behaviour is poorly understood. We determined the dietary patterns and practices relevant to MetS in adults with central obesity attending a mission hospital in Kenya.

STUDY DESIGN

Descriptive, cross-sectional.

SETTING

Outpatient clinic of a mission-based hospital in Nairobi.

PARTICIPANTS

Adults (N=404) aged 18-64 years diagnosed with central obesity as per the International Diabetes Federation definition for MetS.

PRIMARY OUTCOMES

Anthropometric measurements, clinical-biochemical markers and dietary components, quantity and frequency of food intake, as well as time-lapse between consumption of dinner and sleeping.

RESULTS

A high (87.2%) prevalence of MetS was observed for respondents who reported consumption of large amount of carbohydrates (p<0.001), proteins (p<0.001), processed/fast foods (p<0.001) and sugar (p=0.009). Frequent consumption of legumes (p<0.001), nuts (p<0.001), fruits (p<0.001) and vegetables (p=0.021) was linked to reduced MetS. Additionally, longer interval between eating dinner and going to bed was associated with reduced MetS.

CONCLUSION

Regular consumption of fruits, vegetables, legumes and nuts, as well as observing sometime after eating dinner before sleeping, was the dietary pattern significantly associated with a lower risk of MetS. Whereas, consumption of a large quantity of carbohydrates, proteins, processed/fast foods and sugar is likely to predispose to MetS. The findings underscore the need to focus on specific dietary intake patterns including frequency, quantity, quality and variety for MetS prevention and management. The MetS-related interventions could be implemented during individual consultation, group and community health messaging sessions.

Prevalence and correlates of the metabolic syndrome in a cross-sectional community-based sample of 18-100 year-olds in Morocco: Results of the first national STEPS survey in 2017

BACKGROUND AND AIM

Metabolic syndrome (MetS) may be associated with diabetes and cardiovascular diseases. This investigation assessed prevalence and correlates of MetS among adults (18-100 years) in Morocco.

METHOD

Cross-sectional data with complete MetS measurements were analysed from 4555 18-100 year old individuals (median age = 40 years) that took part in the "2017 Morocco STEPS survey." MetS was classified using the harmonized definition.

RESULTS

Two in five participants (40.0%) had MetS, 31.9% among men and 48.0% among women. The average frequency of the five MetS components was 1.9 (1.3 = SD) among men and 2.5 (1.1 = SD) among women. In adjusted logistic and linear regression models, general overweight/obesity, older age, female sex, abnormal waist to hip ratio and low physical activity were associated with the prevalence of MetS and the greater average frequency of MetS components. In addition, in unadjusted analysis, higher education, never married, current smoking and current alcohol use were negatively and urban residence and sedentary behaviour were positively associated with MetS.

CONCLUSION

The study showed that two in five adults were identified as having MetS and that several predictors of MetS were found.

Identification of Body Composition, Dietary Patterns and Its Associated Factors in Medical University Students in China

This study aimed to measure the body composition, dietary patterns and its associated factors in medical students. A cross-sectional study was conducted among 695 students studying at Nanjing medical university, China. Data regarding dietary intake factors was collected by a validated food frequency questionnaire. Principle component analysis and multivariate linear regressions were used. Body composition including BMI and visceral fats index of the males were significantly higher (P < .05) than females. While body fats percentage and fats mass index/free fat mass index (FMI/FFMI) ratio of females was significantly higher (P < .05) than males. Three dietary patterns were identified: western dietary pattern, meat pattern, and vegetables and fruits pattern. The western pattern was having an independent negative association (P < .05) with age and financial status, while positive association (P < .05) with sleeping duration and FMI/FFMI ratio. Vegetables and fruits patterns was having positive association with physical exercise and while negative association with FMI/FFMI ratio. Meat pattern was having positive association with educational levels and sleeping duration, while negative association with physical exercise and FMI/FFMI ratio. In conclusion, medical students adopted less healthy dietary patterns as compared to healthy dietary patterns, which were found to be more associated with some adverse dietary and lifestyle behavior outcomes.

Diets high in vegetables, fruits, cereals, and tubers as a protective factor for metabolic syndrome in bank employees

BACKGROUND

The prevalence of metabolic syndrome (MetS) is increasing, and its development may be related to westernized diets and working conditions.

PURPOSE

The purpose of this study was to evaluate the association of dietary patterns in bank employees with the presence of MetS, considering sociodemographic and behavioral factors as well as laboratory tests.

SUBJECTS AND METHODS

This was a cross-sectional study of 515 bankers. Sociodemographic, occupational, behavioral, and food consumption data were collected. Dietary patterns were determined by principal component analysis with orthogonal varimax rotation.

RESULTS

The dietary pattern of vegetables, fruits, cereals, and tubers was correlated with the presence of MetS and with waist circumference measurements and triglyceride levels. Individuals in the third and fifth quintiles of the pattern "vegetables, fruits, cereals, and tubers" presented with 3.28 and 2.24 times less chances of MetS when compared to individuals in the first quintile of this dietary pattern (OR 0.30, 95% CI 0.13-0.67, and OR 0.44, 95% CI 0.21-0.92, respectively). Subjects over 45 years of age were almost twice as likely to develop MetS (OR 1.95, 95% CI 1.01-3.77).

CONCLUSION

Healthy eating represented by the dietary pattern "vegetables, fruits, cereals, and tubers" was associated with better health among bank employees, especially when evaluating competing metabolic complications such as MetS.

Association between a pro plant-based dietary score and cancer risk in the prospective NutriNet-santé cohort

Diverse plant products (e.g. fruits, vegetables, legumes) are associated with decreased cancer risk at several locations while red and processed meat were found to increase cancer risk. A pro plant-based dietary score reflecting the relative contribution of consumed plant vs animal products was developed, and was associated with lower overall mortality, type 2 diabetes and cardiovascular disease risk, among omnivorous adults. For the first time, we investigated the prospective associations between this pro plant-based dietary score and cancer risk. This study included 42,544 men and women of the French NutriNet-Santé prospective cohort (2009-2016) aged ≥45 years who completed at least three 24-hr-dietary records during the first year of follow-up. The risk of developing cancer was compared across sex-specific tertiles of pro plant-based dietary score by multivariable Cox models. In total, 1,591 first primary incident cancer cases were diagnosed during follow-up, among which 487 breast, 243 prostate, 198 digestive and 68 lung cancers. A higher pro plant-based dietary score was associated with decreased risks of overall (HR_t3vs.t1 =0.85; 95% CI 0.76, 0.97; P_trend =0.02), digestive (HR_t3vs.t1 =0.68; 95% CI 0.47; 0.99; P_trend  = 0.04) and lung (HR_t3vs.t1 =0.47; 95% CI 0.25, 0.90; P_trend =0.02) cancer, though no substantial associations were found for breast or prostate cancers. This large cohort study supports a beneficial role of higher intakes of plant-based products along with lower intakes of animal products, within a balanced omnivorous diet, regarding primary cancer prevention. These results are consistent with mechanistic evidence from experimental studies.
