Mansouri F, de Simone G, Bordoni L, Gabbianelli R. The effects of non-soy legumes consumption on serum levels of inflammatory biomarkers and Adiponectin in overweight/obese adults: A systematic review and meta-analysis of Randomized Controlled Trials. J Nutr Biochem 2024:109718. [PMID: 39103105 DOI: 10.1016/j.jnutbio.2024.109718] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Revised: 07/22/2024] [Accepted: 07/31/2024] [Indexed: 08/07/2024]
Abstract
OBJECTIVES Non-soy legumes offer many health benefits, including improved arterial function, reduced cholesterol levels, and better management of cardiovascular diseases and type 2 diabetes. This systematic review and meta-analysis aim to clarify the inconclusive findings from randomized controlled trials (RCTs) by comprehensively evaluating the effects of non-soy legumes consumption on serum levels of inflammatory biomarkers and Adiponectin. METHODS The search encompassed databases up to January 2024, including PubMed, EMBASE, MEDLINE, Scopus, Web of Science, and Cochrane CENTRAL to retrieve all RCTs examining the effects of non-soy legumes on inflammatory biomarkers or Adiponectin. The effect sizes quantified as mean differences (MD) and standard deviations (SD) of outcomes, and an overall effect estimate was derived using a random-effects model. RESULTS RCTs examining serum levels of C-reactive protein (CRP), Interleukin-6 (IL-6), Tumor Necrosis Factor-alpha (TNF-α), Interleukin-1β (IL-1β), and Adiponectin were included in the final meta-analysis. Results revealed that consumption of non-soy legumes increased Adiponectin serum levels (p = 0.0017) and reduced IL-1β serum levels (p < 0.0001). However, it may not significantly affect CRP (p = 0.2951), IL-6 (p = 0.2286), and TNF-α (p = 0.6661) levels. Subgroup analyses showed that non-soy legumes consumption significantly decreased TNF-α serum levels in studies involving healthy participants. Additionally, sensitivity analysis using the leave-one-out method suggested a potential significant reduction in serum levels of IL-6. CONCLUSIONS This study indicates that consuming non-soy legumes can increase levels of Adiponectin and decrease serum levels of IL-1β in overweight or obese adults.

Abstract
We examined the association between soy isoflavone intake and risk of cardiovascular disease (CVD) outcomes in adults. We searched the online databases for relevant studies published up to September 2021. In total, 13 publications were included in the systematic review and 12 in the meta-analysis. We found that a high intake of soy isoflavones was significantly associated with a lower risk of coronary heart disease (CHD) among whole populations (Pooled RR: 0.92, 95% CI: 0.85-0.99, I2 = 41.0%, Pheterogeneity = 0.10) and a lower risk of overall CVD (Pooled RR: 0.91, 95% CI: 0.84-0.98, I2 = 30.7%, Pheterogeneity = 0.19) and CHD (Pooled RR: 0.89, 95% CI: 0.83-0.96, I2 = 14.4%, Pheterogeneity = 0.32) among Western population. In the linear dose-response analysis, a 3 mg/day increase in soy isoflavone intake was associated with 16% and 14% lower risks of overall CVD and CHD, respectively, among Western population. In conclusion, we found that soy isoflavone intake was associated with a lower risk of overall CVD and CHD in adults, particularly among Western population.

Abstract
Pulses-comprising the dry, edible seeds of leguminous plants-have long been lauded for their culinary flexibility and substantial nutritional advantages. This scoping review aimed to map the evidence on how pulses contribute to overall human health. Four electronic databases were searched for clinical and observational studies in English. We identified 30 articles (3 cross-sectional studies, 1 federated meta-analysis, 8 prospective cohort studies, 1 before-and-after study, and 17 randomized controlled trials) that met our inclusion criteria. Predominant among the pulses studied were lentils, chickpeas, common bean varieties (e.g., pinto, black, navy, red, kidney), black-eyed peas, cowpeas, and split peas. Consumption modalities varied; most studies examined mixed pulses, while five isolated individual types. In intervention studies, pulses were incorporated into diets by allotting a fixed pulse serving on top of a regular diet or by substituting red meat with pulses, offering a comparative analysis of dietary effects. The health outcomes evaluated were multifaceted, ranging from lipid profiles to blood pressure, cardiovascular disease risk and mortality, type 2 diabetes and glycemic control, metabolic syndrome indicators, inflammatory markers, oxidative stress biomarkers, and hormonal profiles. The most frequently assessed study outcomes included changes in low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, systolic blood pressure, diastolic blood pressure, fasting blood sugar, hemoglobin A1c, waist circumference, and C-reactive protein or high-sensitivity C-reactive protein. This review should serve as a call to action for the scientific community to build upon the existing evidence, enriching our understanding of the nutritional and health-promoting attributes of pulses.

Twelve Weeks of Daily Lentil Consumption Improves Fasting Cholesterol and Postprandial Glucose and Inflammatory Responses-A Randomized Clinical Trial. Nutrients 2024; 16:419. [PMID: 38337705 PMCID: PMC10857178 DOI: 10.3390/nu16030419] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Revised: 01/25/2024] [Accepted: 01/27/2024] [Indexed: 02/12/2024] Open
Abstract
Lentils have potential to improve metabolic health but there are limited randomized clinical trials evaluating their comprehensive impact on metabolism. The aim of this study was to assess the impact of lentil-based vs. meat-based meals on fasting and postprandial measures of glucose and lipid metabolism and inflammation. Thirty-eight adults with an increased waist circumference (male ≥ 40 inches and female ≥ 35 inches) participated in a 12-week dietary intervention that included seven prepared midday meals totaling either 980 g (LEN) or 0 g (CON) of cooked green lentils per week. Linear models were used to assess changes in fasting and postprandial markers from pre- to post-intervention by meal group. Gastrointestinal (GI) symptoms were assessed through a survey randomly delivered once per week during the intervention. We found that regular consumption of lentils lowered fasting LDL (F = 5.53, p = 0.02) and total cholesterol levels (F = 8.64, p < 0.01) as well as postprandial glucose (β = -0.99, p = 0.01), IL-17 (β = -0.68, p = 0.04), and IL-1β (β = -0.70, p = 0.03) responses. GI symptoms were not different by meal group and all symptoms were reported as "none" or "mild" for the duration of the intervention. Our results suggest that daily lentil consumption may be helpful in lowering cholesterol and postprandial glycemic and inflammatory responses without causing GI stress. This information further informs the development of pulse-based dietary strategies to lower disease risk and to slow or reverse metabolic disease progression in at-risk populations.

Abstract
Chickpea (Cicer arietinum L.), an annual plant of the Fabaceae family, is mainly grown in temperate and semiarid regions. Its biological activity and beneficial contribution to human health have been scientifically confirmed as an essential source of nutritional components. The objective of this review was to summarize and update latest available scientific data and information, on bioactive components in chickpea, bio-activities, and molecular mechanisms, which has mainly focused on the detection of relevant biochemical indicators, the regulation of signaling pathways, essential genes and proteins. The studies have shown that chickpea have significant multifunctional activities, which are closely related to the functionally active small molecule peptides and phytochemicals of chickpea. Significantly, numerous studies have only addressed the functional activity and mechanisms of single active components of chickpea, however, overlooking the synergy and antagonism between chickpea components, changes of functional active components in different processing methods, as well as the active form of the substances after human digestion and metabolism. Additionally, due to limitations in research methods and techniques, the structure of most functional active substances have not been determined, which makes it difficult to conduct interaction mechanism studies. Consequently, the significant bio-activity of the functional components of chickpea, synergistic and antagonistic effects and activity differences between bioactive components should be further studied.

Abstract
BACKGROUND & AIMS This systematic review sought to identify and summarize existing evidence for the impact of nutrition on the development, progression, and outcomes of peripheral artery disease (PAD). METHODS We performed a systematic literature search of available studies published between January 1974 and December 2019. Randomized controlled trials (RCT), observational studies, and cross-sectional studies reporting either the primary or secondary prevention of PAD with nutritional intake were included. The quality assessment was performed for the RCTs, without pooling a meta-risk estimate. RESULTS Among a total of 8502 records screened, 186 full texts were assessed for eligibility, and 82 studies (30% RCT) were analyzed. The nutrients were structured in fruits, vegetables and antioxidants, fats and oils, dietary fiber, meat, proteins, vitamins and trace elements, and diets and lifestyle. The findings of the current systematic review indicate that the Mediterranean diet, nuts, and polyunsaturated fat are associated with a lower incidence of PAD and saturated fat, cholesterol, and processed meat were associated with higher rates of cardiovascular events in patients suffering from PAD. CONCLUSIONS The current review found evidence of a beneficial impact of the Mediterranean diet including nuts in this target population. More RCTs and high-quality registries are needed that focus on nutritional habits among patients with PAD to design appropriate preventive programs.

Abstract
Peripheral artery disease (PAD) has high morbidity and mortality rates. A metabolomics approach was employed to determine whether consumption of bean-rich diets for 8 weeks would impact the metabolomic profile of PAD individuals. Serum and urine, collected from 54 participants with clinical PAD at baseline and after 8 weeks on 0.3 cups beans/d (n=19), 0.6 cups beans/d (n= 20), or control (n=23) diet, and the beans were extracted and analyzed using LC-QTOF-MS. As a result, PGE2 p-acetamidophenyl ester, PGF2α diethyl amide and 5-L-glutamyl-L-alanine were significantly changed in the serum or urine of bean groups compared to control. Significant changes (P<0.05) in the profile and/or levels of 22 flavonoids present in bean extracts showed the potential importance of the mixture of beans used in this study. In a subset of participants taking metoprolol, after 8 weeks the bean-rich diets significantly elevated metoprolol in the serum while reducing it in urine compared to baseline. In addition, the diets significantly enhanced the urinary excretion of metformin. In conclusion, several biochemical pathways including prostaglandins and glutathione were affected by bean consumption. Significant changes in the metabolism of metoprolol and metformin with bean consumption suggested the presence of diet-drug interactions that may require adjustment of the prescribed dose. ClinicalTrials.gov Identifier: NCT01382056 Novelty: • Bean consumption by people with PAD alters the levels of certain metabolites in serum and urine • Different bean types (black, red kidney, pinto, navy) have unique flavonoid profiles • Metabolomics revealed potential diet-dug interactions as serum and/or urinary levels of metoprolol and metformin are modified by bean consumption.

Abstract
BACKGROUND Recently, it has been proposed that red meat consumption could enhance risk of diabetes and worsen lipid profile and glycemic status, in comparison with soy or non-soy legume, but the results of clinical trials are controversial. OBJECTIVES This study aimed to compare the effect of red meat, soy bean, and non-soy legume consumption on cardio-metabolic factors in patients with type 2 diabetes. METHODS This was a randomized controlled clinical trial which included 75 patients with diabetes, aged 40-65 years. Participants were randomly allocated to receive two servings of red meat (control group), soy bean, or non-soy legume, 3 days a week for 8 weeks. All groups also received a balanced-macronutrients weight maintenance diet. Body composition and cardio-metabolic factors including fasting blood glucose (FBG), fasting insulin, glycated hemoglobin (HbA1c), serum lipids, and blood pressure were measured at baseline and endpoint of the study. Quantitative insulin sensitivity check index (QUICKI) score and Framingham risk score (FRS) were also computed. RESULTS We found no significant differences in changes of FBG, fasting insulin, HbA1c, QUICKI score, serum lipids, FRS, and systolic and diastolic blood pressure among the 3 groups. Within group analysis showed that FRS reduced significantly in all groups (P<0.05). In addition, systolic (P=0.01) and diastolic (P=0.03) blood pressure reduced within red meat group. CONCLUSIONS Compared to soy bean or non-soy legume, moderate consumption of red meat had no adverse effect on cardio-metabolic factors including FBG, fasting insulin, HbA1C, QUICKI score, total cholesterol, low-density lipoprotein , high-density lipoprotein , and blood pressure in adults with type 2 diabetes.

Abstract
BACKGROUND Various foods are known to have beneficial effects on health when consumed whole; however, there is a trend towards preparing foods from processed ingredients, and it remains unclear whether the benefits of the whole food are retained. The purpose of this study was therefore to examine whether different processing techniques affect the lowering of cholesterol and the vascular effects of black beans (Phaseolus vulgaris L.). RESULTS Beans were prepared by overnight soaking and boiling - the standard method - and by micronization, extrusion, or dehulling and boiling, and they were then fine milled. Beans prepared by the standard method were also coarse milled. These five materials were incorporated into semi-purified diets (30% wt/wt) and fed to spontaneously hypertensive rats for 4 weeks. Body weight, blood pressure, and aorta morphology were unaltered by the diets. Fasting total cholesterol was significantly reduced in rats fed micronized beans compared with extruded beans (both fine-milled) or the bean-free diet, while boiling combined with coarse milling lowered low-density lipoprotein (LDL) cholesterol. The lack of cholesterol lowering in rats fed extruded bean compared to micronized was not explained by the amount or composition of dietary fiber or resistant starch. Differences in the polyphenolic profile as determined by high-performance liquid chromatography (HPLC) were also unable to explain the variations in cholesterol-lowering capacity. CONCLUSION The present study demonstrates that processing of black beans alters the health effects observed with the whole pulse, and suggests that products prepared with processed ingredients will need to be tested empirically to establish whether the biological effects are maintained in vivo. © 2020 Society of Chemical Industry.

Abstract
BACKGROUND AND AIMS Consuming pulses (dry beans, dry peas, chickpeas, lentils) over several weeks can improve vascular function and decrease cardiovascular disease risk; however, it is unknown whether pulses can modulate postprandial vascular responses. The objective of this study was to compare different bean varieties (black, navy, pinto, red kidney) and white rice for their acute postprandial effects on vascular and metabolic responses in healthy individuals. METHODS AND RESULTS The study was designed as a single-blinded, randomized crossover trial with a minimum 6 days between consumption of the food articles. Vascular tone (primary endpoint), haemodynamics and serum biochemistry (secondary endpoints) were measured in 8 healthy adults before and at 1, 2, and 6 h after eating ¾ cup of beans or rice. Blood pressure and pulse wave velocity (PWV) were lower at 2 h following red kidney bean and pinto bean consumption compared to rice and navy bean, respectively (p < 0.05). There was greater vasorelaxation 6 h following consumption of darker-coloured beans, as shown by decreased vascular tone: PWV was lower after consuming black bean compared to pinto bean, augmentation pressure was lower after consuming black bean compared to rice and pinto bean, and wave reflection magnitude was lower after consuming red kidney bean and black bean compared to rice, navy bean, and pinto bean (p < 0.05). LDL-cholesterol concentrations were lower 6 h after black bean consumption compared to rice (p < 0.05). CONCLUSION Overall, red kidney and black beans, the darker-coloured beans, elicited a positive effect on the tensile properties of blood vessels, and this acute response may provide insight for how pulses modify vascular function.

Associations between Intake of Dietary Flavonoids and 10-Year Incidence of Age-Related Hearing Loss. Nutrients 2020; 12:nu12113297. [PMID: 33126490 PMCID: PMC7693883 DOI: 10.3390/nu12113297] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Revised: 10/23/2020] [Accepted: 10/27/2020] [Indexed: 01/12/2023] Open
Abstract
Dietary flavonoids are vasoactive phytochemicals with promising anti-inflammatory properties. We aimed to assess the associations between baseline intakes of six commonly consumed flavonoid subclasses and 10-year incidence of age-related hearing loss. At baseline, 1691 participants aged 50+ years had information on dietary intakes and hearing status. Hearing loss was defined as the pure-tone average of frequencies 0.5, 1.0, 2.0, and 4.0 kHz > 25 dB hearing level (HL). Dietary data were collected through a semi-quantitative food frequency questionnaire. The flavonoid content of foods was estimated using US databases. During the 10-year follow-up, 260 (31.6%) new cases of hearing loss (incident) were observed. After multivariable adjustment, participants in the fourth versus first quartile (reference group) of intake of dietary isoflavone had 36% lower risk of incident hearing loss after 10 years: odds ratios (OR) 0.64 (95% confidence intervals, CI, 0.42–0.99); p-value for trend = 0.03. Nonsignificant associations were observed between the other five flavonoid subclasses and 10-year incidence of hearing loss. Our findings do not support the hypothesis that the intake of dietary flavonoids protect against long-term risk of hearing loss. The association with isoflavone intake needs to be confirmed by other population-based studies.

Abstract
BACKGROUND Whether soy products confer health benefits related to coronary heart disease (CHD) remains controversial because of inconsistent evidence. METHODS A total of 74 241 women from the NHS (Nurses' Health Study; 1984-2012), 94 233 women from the NHSII (Nurses' Health Study II; 1991-2013), and 42 226 men from the Health Professionals Follow-Up Study (1986-2012), who were free of cardiovascular disease and cancer at baseline, were included in the present analysis. Dietary data were updated every 2 to 4 years using a validated food frequency questionnaire. Nonfatal myocardial infarction and CHD deaths were adjudicated through reviewing medical records, death certificates, and other medical documents. RESULTS In these cohorts, 8359 incident CHD cases were documented during 4 826 122 person-years of follow-up. In multivariable-adjusted analyses, isoflavone intake was inversely associated with CHD (pooled hazard ratio [HR] comparing the extreme quintiles: 0.87 [95% CI, 0.81-0.94]; P=0.008). Consumption of tofu, but not soy milk, was inversely associated with the risk of CHD, with pooled HRs (95% CIs) of 0.82 (0.70-0.95; P=0.005) and 0.87 (0.69-1.10; P=0.41), respectively, comparing ≥1 serving/week with <1 serving/month. Further analyses showed that, in women, the favorable association of tofu was primarily driven by stronger inverse association of tofu intake observed in younger women before menopause and postmenopausal women without hormone use (Pinteraction=0.002). CONCLUSIONS Higher intake of isoflavones and tofu was associated with a moderately lower risk of developing CHD, and in women the favorable association of tofu were more pronounced in young women or postmenopausal women without hormone use.

Abstract
Background Development of instruments capable of detecting early stage vascular disease has increased interest in employing arterial stiffness (e.g. pulse wave velocity (PWV), augmentation index (AIx)) and endothelial dysfunction (e.g. reactive hyperemia index (RHI)) to diagnose atherosclerotic disease before occurrence of a cardiovascular event. However, amongst the equipment designed for this purpose, there is insufficient information regarding each of these parameters to establish appropriate cutoffs to distinguish between healthy and unhealthy blood vessels. To address these limitations, the study was designed to establish the upper arterial stiffness and endothelial function thresholds in a healthy population, by comparing the outputs from different instruments capable of measuring PWV, AIx and RHI. Methods A systematic comparison of PWV, AIx and RHI was conducted to determine the inter-relationships between these parameters of vascular functionality. Outputs were obtained non-invasively using three instruments, the VP-1000 (VP), SphygmoCor (SC), and EndoPAT (EP), in 40 apparently healthy males and females. Results Correlations were found between the brachial-ankle PWV and radial-ankle PWV (by VP and SC), and PWV (VP) with AIx (SC). The interchangeability of these outputs was demonstrated by the Bland Altman test, making it feasible to extrapolate cut-offs for radial-ankle PWV and AIx equivalent to brachial-ankle PWV that signify healthy vessels. In contrast, RHI showed no association with AIx, suggesting these endothelial and arterial parameters are functionally distinct. Conclusions It was concluded that it is possible to compare the vascular function outputs of different instruments and identify healthy from unhealthy vessels, even though the approaches for quantifying the underlying physiological processes may differ. In this way, non-invasive determination of arterial function could be a new paradigm for detecting existing early stage asymptomatic atherosclerotic disease in individuals using techniques that are amenable to the clinical setting.

Abstract
Pulses are nutrient-rich ingredients used as interventions in clinical trials to determine their effect on lowering blood lipids, which are risk factors for cardiovascular disease. Acceptability of these foods is critical for compliance by participants in clinical trials as well as regular consumption by those eating them for their health benefit. Commercialisation of foods that prove positive for health is required to make them available to the general population. Since the target for commercialisation would be products that will be procured by as many people as possible, the research question becomes whether or not testing is required by the clinical trial participants, by consumer acceptability testing in a sensory unit, or by both to ensure acceptability. The objective of this study was to determine the acceptability of pulse-based soups and casseroles destined for a clinical trial by both the participants in the clinical trial and by consumer participants not in the clinical trial. Neither group received any training regarding sensory analysis. Acceptability of aroma, appearance, flavor, texture, overall acceptability, and the frequency of eating the samples of five formulations fortified with either peas or beans was measured. Groups differed in their acceptability of foods for different attributes with the clinical trial participants providing less discrimination among the sensory attributes for their acceptability. Influential factors could include motivation for healthy eating, age, number of times the product was consumed, amount of the product consumed, and where it was consumed. In conclusion, acceptance measures from both groups are required in order to gain as much information as possible regarding acceptability of attributes for commercialisation of pulse-fortified foods that provide a health benefit.

Abstract
Insulin resistance is a major risk factor for diseases such as type 2 diabetes and metabolic syndrome. Current methods for management of insulin resistance include pharmacological therapies and lifestyle modifications. Several clinical studies have shown that leguminous plants such as soybeans and pulses (dried beans, dried peas, chickpeas, lentils) are able to reduce insulin resistance and related type 2 diabetes parameters. However, to date, no one has summarized the evidence supporting a mechanism of action for soybeans and pulses that explains their ability to lower insulin resistance. While it is commonly assumed that the biological activities of soybeans and pulses are due to their antioxidant activities, these bioactive compounds may operate independent of their antioxidant properties and, thus, their ability to potentially improve insulin sensitivity via alternative mechanisms needs to be acknowledged. Based on published studies using in vivo and in vitro models representing insulin resistant states, the proposed mechanisms of action for insulin-sensitizing actions of soybeans, chickpeas, and their bioactive compounds include increasing glucose transporter-4 levels, inhibiting adipogenesis by down-regulating peroxisome proliferator-activated receptor-γ, reducing adiposity, positively affecting adipokines, and increasing short-chain fatty acid-producing bacteria in the gut. Therefore, this review will discuss the current evidence surrounding the proposed mechanisms of action for soybeans and certain pulses, and their bioactive compounds, to effectively reduce insulin resistance.

Abstract
OBJECTIVE Vegetarian diets contain various anti-inflammatory components. We aimed to investigate the effects of vegetarianism on inflammatory biomarkers when compared with omnivores. DESIGN Systematic review and meta-analysis. SETTING Literature search was conducted in Science Direct, Proquest, MEDLINE and Google Scholar up to June 2016. Summary estimates and corresponding 95 % CI were derived via the DerSimonian and Laird method using random effects, subgroup analyses were run to find the source of heterogeneity and a fixed-effect model examined between-subgroup heterogeneity. SUBJECTS Studies were included if they evaluated effects of any type of vegetarianism compared with omnivores on circulating levels of inflammatory biomarkers. No restriction was made in terms of language or the date of study publications. RESULTS Eighteen articles were included. Pooled effect size showed no difference in high-sensitivity C-reactive protein (hs-CRP) levels in vegetarians v. omnivores (Hedges' g=-0·15; 95 % CI -0·35, 0·05), with high heterogeneity (I 2=75·6 %, P<0·01). A subgroup analysis by minimum duration of vegetarianism showed that a minimum duration of 2 years vegetarianism was associated with lower hs-CRP levels v. omnivores (Hedges' g=-0·29; 95 % CI -0·59, 0·01), with moderate heterogeneity (I 2=68·9 %, P<0·01). No significant effect was found in studies using a minimum duration of 6 months of vegetarianism, with low heterogeneity. Vegetarianism was associated with increased IL-6 concentrations (0·21 pg/ml; 95 % CI 0·18, 0·25), with no heterogeneity (I 2=0·0 %, P=0·60). CONCLUSIONS The meta-analysis provides evidence that vegetarianism is associated with lower serum concentrations of hs-CRP when individuals follow a vegetarian diet for at least 2 years. Further research is necessary to draw appropriate conclusions regarding potential associations between vegetarianism and IL-6 levels. A vegetarian diet might be a useful approach to manage inflammaging in the long term.

Abstract
BACKGROUND & AIMS Diet quality may influence non-traditional cardiovascular disease (CVD) risk factors - namely, C-reactive protein (CRP) and the ankle-brachial index (ABI). Pre-existing traditional cardiometabolic conditions may confound this association. We aimed to determine whether diet quality was associated with high-risk CRP or ABI, independently from traditional cardiometabolic risk factors. METHODS Baseline data were analyzed from US-Hispanics/Latinos aged 18-74 y without previously-diagnosed CVD participating in the population-based Hispanic Community Health Study/Study of Latinos cohort. Included were 14,623 participants with CRP data, and 7892 participants (≥45 y) with ABI data. Diet quality was measured with the Alternate Healthy Eating Index (AHEI). RESULTS Nearly 35% of Hispanics/Latinos had high-risk CRP concentration and 6.3% had high-risk ABI (peripheral artery disease (PAD): 4.2%; arterial stiffness: 2.1%). After adjusting for sociodemographic and lifestyle factors, diabetes, hypertension, hypercholesterolemia, and obesity, the odds (95% confidence interval) of having high-risk ABI were 37% (5, 44%) lower per 10-unit increase in AHEI (p = 0.018). The association was marginally significant for PAD (0.77 (0.58, 1.00); p = 0.05), and non-significant for arterial stiffness (p = 0.16). Each 10-unit increase in AHEI was associated with 21% (10, 30%) lower odds of high-risk CRP (p = 0.0002) after similar adjustments. There were no significant interactions between AHEI and age, sex, ethnicity, smoking, or pre-existing cardiometabolic conditions for associations with ABI. The association between AHEI and high-risk CRP was stronger for those with diabetes (p-interaction < 0.0001), obesity (p-interaction = 0.005), or ages 45-74 y (p-interaction = 0.011). CONCLUSIONS Higher diet quality is associated with lower inflammation and less adverse ABI among Hispanics/Latinos, independently from traditional cardiometabolic risk factors.

Abstract
The present study investigated the feasibility, tolerability, and adherence of daily consumption of whole pulses (dried beans, peas, lentils, chickpeas) by individuals with peripheral artery disease participating in an 8-week study. Study questionnaires and semi-structured interviews for 26 participants were used to determine prestudy pulse consumption and participants' experiences with respect to adherence, positive and negative effects, bowel routine, satiety, and enjoyment of the foods. Although the majority of participants rarely consumed pulses prior to the study, there was a high rate of adherence to daily consumption of the study foods for 8 weeks despite comments regarding study fatigue during the latter part of the study. Participants had no gastrointestinal side effects (42%) or experienced flatulence that resolved by week 4 (23%), whereas 62% reported improvements in their bowel pattern. By week 8 greater satiety was noted by some participants (19%), with the categories "less afternoon snacking" and "not snacking" receiving more responses. The key finding of this study was that consumption of pulses is a viable approach for this population; however, the frequency of consumption that is tolerable in the long term should be integrated with the dose and timeframe required to achieve and maintain health benefits.

Abstract
We previously established that lentils were able to significantly attenuate the development of hypertension in spontaneously hypertensive rats (SHRs), but the mechanism was not investigated. The current study was therefore designed to examine the effect of lentils on arterial function in relation to arterial stiffness, lipid biochemistry and activation of select aortic proteins. Seventeen-week-old male SHRs were randomly assigned to groups (n=10/group) fed (a) 30% w/w green lentils, (b) 30% red lentils, (c) 30% mixed lentils (red and green) or (d) no lentils for 8 weeks. Normotensive Wistar Kyoto (WKY) groups (n=10/group) received either the mixed lentil or no lentil diet. Blood pressure, pulse wave velocity and serum lipids were measured at baseline and 8 weeks, while pressure myography, arterial morphology and aortic proteins were measured after termination. There were no dietary-related changes in pulse wave velocity or blood pressure for any SHR or WKY group. Low-density lipoprotein cholesterol and high-density lipoprotein cholesterol were significantly lower in only SHR red lentil and WKY mixed lentil groups compared to their controls. The lentil diets reduced the media:lumen ratio of SHRs relative to control-fed SHRs but had no effect on WKYs. Both red and green lentils reduced arterial stiffness of SHRs but not WKYs. SHR lentil groups showed lower aortic p38 mitogen-activated protein kinase (p38MAPK) phosphorylation, thus implying that p38MAPK activation is suppressed with lentil feeding. Lentil-based diets suppress pathological vascular remodeling in SHRs, while green lentils maintain the vascular function of SHRs similar to normotensive WKYs despite the presence of high blood pressure.

Abstract
The present randomised cross-over clinical trial investigated the effects of two intervention diets (non-soya legume-based therapeutic lifestyle change (TLC) diet v. isoenergetic legume-free TLC diet) on inflammatory biomarkers among type 2 diabetic patients. A group of thirty-one participants (twenty-four women and seven men; weight 74.5 (SD 7.0) kg; age 58.1 (SD 6.0) years) were randomly assigned to one of the two following intervention diets for 8 weeks: legume-free TLC diet or non-soya legume-based TLC diet. The latter diet was the same as the legume-free TLC diet, except that two servings of red meat were replaced with different types of cooked non-soya legumes such as lentils, chickpeas, peas and beans over a period of 3 d per week. The intervention period was followed by a washout period of 4 weeks, after which the groups followed the alternate treatment for 8 weeks. Concentrations of inflammatory markers were measured at baseline and after the intervention periods. Compared with the legume-free TLC diet, the non-soya legume-based TLC diet significantly decreased high-sensitivity C-reactive protein, IL-6 and TNF-α in overweight diabetic patients. The replacement of two servings of red meat by non-soya legumes in the isoenergetic TLC diet for a period of 3 d per week reduced the plasma concentrations of inflammatory markers among overweight diabetic patients, independent of weight change.

Substitution of red meat with legumes in the therapeutic lifestyle change diet based on dietary advice improves cardiometabolic risk factors in overweight type 2 diabetes patients: a cross-over randomized clinical trial. Eur J Clin Nutr 2014; 69:592-7. [PMID: 25351652 DOI: 10.1038/ejcn.2014.228] [Citation(s) in RCA: 54] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2014] [Revised: 08/30/2014] [Accepted: 09/12/2014] [Indexed: 12/21/2022]
Abstract
BACKGROUND/OBJECTIVE The objective of this study was to determine the effects of substitution of red meat with legumes in the Therapeutic Lifestyle Change (TLC) diet on cardiometabolic risk factors in type 2 diabetes patients based on dietary education. SUBJECTS/METHODS This study was a randomized, controlled, cross-over trial. Thirty-one participants (24 women and 7 men; age: 58.1 ± 6.0 years) with type 2 diabetes were randomly assigned to consume a control diet (legume-free TLC diet) and legume-based TLC diet for 8 weeks. Legume-based TLC diet was the same as the control diet, but the legume-based TLC group was advised to replace two servings of red meat with legumes, 3 days per week. After the interventional period, a washout period was conducted for 4 weeks. The groups were then advised to follow the alternate treatment for 8 weeks. Cardiometabolic risk factors were measured. RESULTS Compared with the legume-free TLC diet, the legume-based TLC diet significantly decreased fasting blood glucose (P=0.04), fasting insulin (P=0.04), triglyceride concentrations (P=0.04) and low-density lipoprotein cholesterol (P=0.02). Total cholesterol concentrations decreased after consumption of both TLC diet and legume TLC diet; however, the data did not differ significantly between the two diets. body mass index (BMI), waist circumference, systolic and diastolic blood pressures did not change significantly after consumption of either the legume-free TLC diet or the legume-based TLC diet. CONCLUSIONS Dietary advice given for substitution of red meat with legume intakes within a TLC diet-improved lipid profiles and glycemic control among diabetes patients, which were independent from BMI change. This trial was registered in the Iranian Registry of Clinical Trials (http://www.irct.ir) as IRCT201202251640N7.

Urantide improves atherosclerosis by controlling C-reactive protein, monocyte chemotactic protein-1 and transforming growth factor-β expression in rats. Exp Ther Med 2014; 7:1647-1652. [PMID: 24926360 PMCID: PMC4043621 DOI: 10.3892/etm.2014.1654] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2013] [Accepted: 03/18/2014] [Indexed: 12/20/2022] Open
Abstract
The aim of the present study was to investigate the effects of urantide on the expression status of C-reactive protein (CRP) and the inflammatory cytokines monocyte chemotactic protein (MCP)-1 and transforming growth factor (TGF)-β in the aortas of rats with atherosclerosis (AS), and to identify its underlying mechanisms. The effects of urantide in a rat model of AS and in cultured rat vascular smooth muscle cells (VSMCs) were analyzed via hematoxylin and eosin staining, immunohistochemical staining and ELISA. The results in vivo demonstrated that urantide downregulated the expression of inflammatory mediators CRP and MCP-1 and upregulated the expression of TGF-β. The results in vitro indicated that urantide inhibited the proliferation of VSMCs. In addition, urantide reduced the expression of CRP and downregulated the secretion of TGF-β in the culture supernatant. In conclusion, urantide ameliorated the arterial inflammatory damage that was observed in the AS rat model at the cell and tissue levels by controlling the expression of CRP and the inflammatory cytokines MCP-1 and TGF-β. Therefore, urantide may be a potential agent for the complementary treatment of AS.
