DNA methylation and non-coding RNAs in metabolic disorders: Epigenetic Roles of Nutrients, Dietary Patterns and Weight Loss Interventions for Precision Nutrition.

Dysregulation of epigenetic processes and abnormal epigenetic profiles are associated with various metabolic disorders. Nutrition, as an environmental factor, can induce epigenetic changes through both direct exposure and transgenerational inheritance, continuously altering gene expression and shaping the phenotype. Nutrients consumed through food or supplementation, such as vitamin B12, folate, vitamin B6, and choline, play a pivotal role in DNA methylation, a critical process for gene regulation. Additionally, there is mounting evidence that the expression of non-coding RNAs (ncRNAs) can be modulated by the intake of specific nutrients and natural compounds, thereby influencing processes involved in the onset and progression of metabolic diseases. Evidence suggests that dietary patterns, weight-loss interventions, nutrients and nutritional bioactive compounds can modulate the expression of various miRNAs and DNA methylation levels, contributing to development of metabolic disorders such as obesity and type 2 diabetes. Furthermore, several studies have proposed that DNA methylation and microRNA (miRNA) expression could serve as biomarkers for the effects of weight-loss programs. Despite ongoing debate regarding the effects of nutrient supplementation on DNA methylation levels and the expression of ncRNAs, certain DNA methylation marks and ncRNA expressions might predict the risk of metabolic disorders and act as biomarkers for forecasting the success of therapies within the framework of precision medicine and nutrition. The role of DNA methylation and miRNA expression as potential mediators of the effects of weight loss underscores their potential as biomarkers for the outcomes of weight loss programs. This highlights the influence of dietary patterns and weight-loss interventions on the regulation of miRNA expression and DNA methylation levels, suggesting an interaction between these epigenetic factors and the body's response to weight loss.

Dietary diversity and nutrient adequacy among women in Bosomtwe District, Ghana.

The sustainable development goals seek to end all forms of malnutrition of women of reproductive age (WRA) by 2030. As such, recent data on nutrient adequacy are needed to aid in tracking progress. However, data on specific dietary nutrient intakes includes only iron, folate, vitamin A, and vitamin B12 in Ghana. Therefore, women's dietary diversity score (W-DDS) is often used as a proxy measure of nutrient adequacy. It is hypothesised that there is no association between W-DDS and Nutrient Adequacy among WRA in peri-urban Ghana. Hence, this research evaluated the associations between W-DDS and nutrient adequacy ratio (NAR) and assessed the determinants of mean nutrient adequacy ratio (MAR) in the Bosomtwe District of Ghana. A community-based cross-sectional study was conducted, and data collected on anthropometry, food insecurity, socio-demographic characteristics and dietary intake using the 24-hour recall from 407 WRA. In all, 21 nutrients were assessed. The mean age, W-DDS, and MAR were 29.0 ± 6.7 years, 5.3 ± 1.9, and 0.65 ± 0.19 respectively. The NAR were generally high for the macronutrients as compared to micronutrients and the nutrients with low NAR included vitamin C (0.27 ± 0.19), vitamin A (0.15 ± 0.23), vitamin B12 (0.54 ± 0.32), calcium (0.28 ± 0.20), zinc (0.52 ± 0.23) and iron (0.57 ± 0.28) - signifying the WRA may be consuming monotonous carbohydrate-based diet. The hierarchical multivariable linear regression found a significant association between W-DDS and MAR after controlling for confounders (β = 0.404, p < 0.001). The determinants of MAR were ethnicity (β = 0.110, p = 0.006) and body mass index (β = 0.189, p < 0.001). This study supports the use of W-DDS as a proxy indicator of nutrient adequacy. Strategies meant to address nutrient inadequacies should be adaptable to different ethnic groups and overweight-reducing strategies should be incorporated into broader nutrition initiatives.

Nutritional Genomics: The Use of Personalized Diets for Managing Depression

Millions worldwide suffer from major depression, and recent studies have highlighted the effect of diet on mental health. However, research using nutritional genomics to create personalized diets for managing depression is still limited. This review explores the role of nutritional genomics in developing personalized dietary strategies for depression, focusing on key genetic markers. A comprehensive review of current literature, with a focus on studies that analyze the interplay between specific genes, nutrient intake, and depression was carried out. Databases like PubMed, Google Scholar, and Web of Science were searched using keywords like “nutritional genomics,” “personalized diets,” and “depression.” Relevant articles were also selected based on their contribution to how genetic variations affect dietary components linked to mental health. We identified several genetic markers such as SLC6A4 and BDNF that may influence how individuals with depression respond to specific nutrients, such as vitamin D, folate, and omega-3 fatty acids. These markers include variations in genes related to neurotransmitter pathways, inflammation, and neuroplasticity. This review highlights the potential of nutritional genomics as a tool for creating more individualized dietary plans for managing depression. With the use of genetic insights into dietary recommendations, healthcare providers could offer more targeted interventions.

Exhaustive Search of Dietary Intake Biomarkers as Objective Tools for Personalized Nutrimetabolomics and Precision Nutrition Implementation.

To conduct an exhaustive scoping search of existing literature, incorporating diverse bibliographic sources to elucidate the relationships between metabolite biomarkers in human fluids and dietary intake. The search for biomarkers linked to specific dietary food intake holds immense significance for precision health and nutrition research. Using objective methods to track food consumption through metabolites offers a more accurate way to provide dietary advice and prescriptions on healthy dietary patterns by healthcare professionals. An extensive investigation was conducted on biomarkers associated with the consumption of several food groups and consumption patterns. Evidence is integrated from observational studies, systematic reviews, and meta-analyses to achieve precision nutrition and metabolism personalization. Tailored search strategies were applied across databases and gray literature, yielding 158 primary research articles that met strict inclusion criteria. The collected data underwent rigorous analysis using STATA and Python tools. Biomarker-food associations were categorized into 5 groups: cereals and grains, dairy products, protein-rich foods, plant-based foods, and a miscellaneous group. Specific cutoff points (≥3 or ≥4 bibliographic appearances) were established to identify reliable biomarkers indicative of dietary consumption. Key metabolites in plasma, serum, and urine revealed intake from different food groups. For cereals and grains, 3-(3,5-dihydroxyphenyl) propanoic acid glucuronide and 3,5-dihydroxybenzoic acid were significant. Omega-3 fatty acids and specific amino acids showcased dairy and protein foods consumption. Nuts and seafood were linked to hypaphorine and trimethylamine N-oxide. The miscellaneous group featured compounds like theobromine, 7-methylxanthine, caffeine, quinic acid, paraxanthine, and theophylline associated with coffee intake. Data collected from this research demonstrate potential for incorporating precision nutrition into clinical settings and nutritional advice based on accurate estimation of food intake. By customizing dietary recommendations based on individualized metabolic profiles, this approach could significantly improve personalized food consumption health prescriptions and support integrating multiple nutritional data.This article is part of a Nutrition Reviews special collection on Precision Nutrition.

Dietary Pattern's Role in Hepatic Epigenetic and Dietary Recommendations for the Prevention of NAFLD.

Comprehensive screening and eligibility criteria identified eleven articles focusing on epigenetic changes in NAFLD patients through dietary modifications or nutrient supplementation. Data were organized based on study types, categorizing them into evaluations of epigenetic changes in NAFLD patients through dietary pattern modifications or specific nutrient intake. The study highlights the importance of dietary interventions in managing and preventing NAFLD, emphasizing the potential of dietary patterns to influence hepatic epigenetic gene modulation. This study provides valuable insights and recommendations to mitigate the risk of developing NAFLD: (i) eat a primarily plant-based diet; (ii) increase consumption of high-fiber foods; (iii) consume more polyunsaturated and monounsaturated fatty acids; (iv) limit processed foods, soft drinks, added sugars, and salt; and (v) avoid alcohol.

Higher maternal bread and thiamine intakes are associated with increased infant allergic disease.

A mother's diet during pregnancy may influence her infant's immune development. However, as potential interactions between components of our dietary intakes can make any nutritional analysis complex, here we took a multi-component dietary analysis approach. Nutritional intake data was collected from 639 pregnant women using a validated semi-quantitative food frequency questionnaire to reflect their dietary intakes during 32-36 weeks of gestation. To investigate their dietary intake pattern, we calculated Dietary Inflammatory Index scores. Maternal consumption of 12 food groups, 20 individual whole foods, and 18 specific nutrient intakes, along with any vitamin and mineral supplementation, were determined. Infant outcomes included eczema, allergen sensitization, and IgE-mediated food allergy. Regression-based analyses with covariates adjustment were applied. Women with higher white bread consumption were more likely to have an infant with doctor-diagnosed eczema (adjusted relative risk [aRR] 1.16; 95% CI 1.08, 1.24; p < .001) and IgE-mediated food allergy (aRR 1.14; 95% CI 1.02, 1.28; p = .02). Higher maternal intakes of fiber-rich bread (aRR 1.14; 95% CI 1.04, 1.25; p = .01) and legumes (aRR 1.11; 95% CI 1.02, 1.21; p = .02) were also associated with infant doctor-diagnosed eczema. Higher maternal thiamine intakes were associated with increased parent-reported infant eczema (aRR 1.08; 95% CI 1.03, 1.12; p < .001). In Australia, where bread flour is fortified with thiamine, we identified consistent links between higher maternal thiamine-rich diets and increased risk of infant eczema and food allergy. Our results highlight a need for further investigation of potential effects of high thiamine exposures on immune development, especially in-utero.

Dietary factors may be associated with measures of ultrasound-derived skeletal muscle echo intensity.

Skeletal muscle echo intensity (EI) is affected by ageing and physical activity; however, the effects of nutrition are less understood. The aim of this study was to explore whether habitual nutrient intake may be associated with ultrasound-derived EI. Partial least squares regression (PLSR) models were trained on an initial sample (n=100, M=45; F=55; 38±15 years) to predict EI of two quadriceps muscles from 19 variables, using the "jack-knife" function within the "pls" package (RStudio), which was then tested in an additional dataset (n=30, M=13; F=17; 38±16 years). EI was determined using B-mode ultrasonography of the rectus femoris (RF) and vastus lateralis (VL) and nutritional intake determined via 3-day weighed food diaries. Mean daily intake of specific nutrients were included as predictor variables with age, sex, and self-reported physical activity. PLSR training model 1 explained ∼52% and model 2 ∼46% of the variance in RF and VL EI, respectively. Model 1 also explained ∼35% and model 2 ∼30% of the variance in RF and VL EI in the additional testing dataset. Age and biological sex were associated with EI in both models (P<0.025). Dietary protein (RF: β = -7.617, VL: β = -7.480), and selenium (RF: β = -7.144, VL: β = -4.775) were associated with EI in both muscles (P<0.05), whereas fibre intake (RF: β = -5.215) was associated with RF EI only and omega-3 fatty acids (n-3/ω-3 FAs, RF: β = 3.145) with VL EI only (P<0.05). Therefore, absolute protein, selenium, fibre, and n-3 FAs may be associated with skeletal muscle EI, although further mechanistic work is required before claiming causal inference.

The relationship between dietary habits and menstruation problems in women: a cross-sectional study

BackgroundNutrition is important to the management and relief of the symptoms in menstrual disorders. This study aims to investigate the relationship between menstrual disorders and specific foods and nutrient intake in women.MethodsFive-hundred-nine menstruating women participated in the study. The questionnaire form was created by the researchers via Google Forms and distributed in online applications (WhatsApp, Instagram etc.). The questionnaire consists of 5 sections, including demographic data, declared anthropometric measurements (height (m or cm), weight (g or kg)), questions about eating habits, menstruation status, and 24-hour food consumption. Statistical analysis was made with SPSS 23; nutrient analysis of food consumption was made using BeBiS 9.0.ResultsIt was found that the body mass index (BMI) of healthy participants was higher than women with menstrual disorders. Women with menstrual disorders have lower intake of protein, vitamin K, vitamin B3, vitamin B5 and sodium compared with healthy women. All participants have a higher intake of vitamin B3, sodium, phosphorus, and manganese, and have a lower intake of other nutrients compared with the national adequate intake.ConclusionOur findings showed that women with menstrual disorders consume more high-sugar food/beverages and have inadequate nutrients intake.

Diet predisposes to pancreatic cancer through cellular nutrient sensing pathways.

Pancreatic cancer is a lethal disease with limited effective treatments. A deeper understanding of its molecular mechanisms is crucial to reduce incidence and mortality. Epidemiological evidence suggests a link between diet and disease risk, though dietary recommendations for at-risk individuals remain debated. Here, we propose that cell-intrinsic nutrient sensing pathways respond to specific diet-derived cues to facilitate oncogenic transformation of pancreatic epithelial cells. This review explores how diet influences pancreatic cancer predisposition through nutrient sensing and downstream consequences for (pre-)cancer cell biology. We also examine experimental evidence connecting specific food intake to pancreatic cancer progression, highlighting nutrient sensing as a promising target for therapeutic development to mitigate disease risk.

The Association between Dietary Nutrient Intake and Acceleration of Aging: Evidence from NHANES.

The acceleration of aging is a risk factor for numerous diseases, and diet has been identified as an especially effective anti-aging method. Currently, research on the relationship between dietary nutrient intake and accelerated aging remains limited, with existing studies focusing on the intake of a small number of individual dietary nutrients. Comprehensive research on the single and mixed anti-aging effects of dietary nutrients has not been conducted. This study aimed to comprehensively explore the effects of numerous dietary nutrient intakes, both singly and in combination, on the acceleration of aging. Data for this study were extracted from the 2015-2018 National Health and Nutrition Examination Surveys (NHANES). The acceleration of aging was measured by phenotypic age acceleration. Linear regression (linear), restricted cubic spline (RCS) (nonlinear), and weighted quantile sum (WQS) (mixed effect) models were used to explore the association between dietary nutrient intake and accelerated aging. A total of 4692 participants aged ≥ 20 were included in this study. In fully adjusted models, intakes of 16 nutrients were negatively associated with accelerated aging (protein, vitamin E, vitamin A, beta-carotene, vitamin B1, vitamin B2, vitamin B6, vitamin K, phosphorus, magnesium, iron, zinc, copper, potassium, dietary fiber, and alcohol). Intakes of total sugars, vitamin C, vitamin K, caffeine, and alcohol showed significant nonlinear associations with accelerated aging. Additionally, mixed dietary nutrient intakes were negatively associated with accelerated aging. Single dietary nutrients as well as mixed nutrient intake may mitigate accelerated aging. Moderately increasing the intake of specific dietary nutrients and maintaining dietary balance may be key strategies to prevent accelerated aging.

Higher habitual intakes of flavonoids and flavonoid-rich foods are associated with a lower incidence of type 2 diabetes in the UK Biobank cohort

AimTo examine the associations of a diet high in flavonoid-rich foods, as reflected by a “Flavodiet Score” (FDS), the major individual food contributors to flavonoid intake, and flavonoid subclasses with type 2 diabetes (T2D) risk in the UK Biobank cohort.Materials and methodsFlavonoid intakes were estimated from ≥2 dietary assessments among 113,097 study participants [age at enrolment: 56 ± 8 years; 57% female] using the U.S Department of Agriculture (USDA) databases. Multivariable Cox proportional hazards models were used to investigate associations between dietary exposures and T2D.ResultsDuring 12 years of follow-up, 2628 incident cases of T2D were identified. A higher FDS (compared to lower [Q4 vs. Q1]), characterised by an average of 6 servings of flavonoid-rich foods per day, was associated with a 26% lower T2D risk [HR: 0.74 (95% CI: 0.66–0.84), ptrend = <0.001]. Mediation analyses showed that lower body fatness and basal inflammation, as well as better kidney and liver function partially explain this association. In food-based analyses, higher intakes of black or green tea, berries, and apples were significantly associated with 21%, 15%, and 12% lower T2D risk. Among individual flavonoid subclasses, 19–28% lower risks of T2D were observed among those with the highest, compared to lowest intakes.ConclusionsA higher consumption of flavonoid-rich foods was associated with lower T2D risk, potentially mediated by benefits to obesity/sugar metabolism, inflammation, kidney and liver function. Achievable increases in intakes of specific flavonoid-rich foods have the potential to reduce T2D risk.

Intake Biomarkers for Nutrition and Health: Review and Discussion of Methodology Issues.

Metabolomics profiles from blood, urine, or other body fluids have the potential to assess intakes of foods and nutrients objectively, thereby strengthening nutritional epidemiology research. Metabolomics platforms may include targeted components that estimate the relative concentrations for individual metabolites in a predetermined set, or global components, typically involving mass spectrometry, that estimate relative concentrations more broadly. While a specific metabolite concentration usually correlates with the intake of a single food or food group, multiple metabolites may be correlated with the intake of certain foods or with specific nutrient intakes, each of which may be expressed in absolute terms or relative to total energy intake. Here, I briefly review the progress over the past 20 years on the development and application intake biomarkers for foods/food groups, nutrients, and dietary patterns, primarily by drawing from several recent reviews. In doing so, I emphasize the criteria and study designs for candidate biomarker identification, biomarker validation, and intake biomarker application. The use of intake biomarkers for diet and chronic disease association studies is still infrequent in nutritional epidemiology research. My comments here will derive primarily from our research group's recent contributions to the Women's Health Initiative cohorts. I will complete the contribution by describing some opportunities to build on the collective 20 years of effort, including opportunities related to the metabolomics profiling of blood and urine specimens from human feeding studies that approximate habitual diets.

The Role of Diet in the Management of Irritable Bowel Syndrome: A Comprehensive Review.

Irritable bowel syndrome (IBS) is a highly prevalent gastrointestinal disorder that has a significant impact on the general population. The suboptimal medical treatments available for IBS contribute to its large economic burden. The pathophysiology of IBS is complex, and treatments often focus on managing specific symptoms. Many individuals with IBS associate their symptoms with specific food intake, leading to increased scientific research on the role of diet in managing IBS. Dietary management has become a crucial aspect of IBS treatment, with initial recommendations focusing on adopting a healthy eating pattern and lifestyle. This comprehensive review aims to synthesise the current literature on the impact of diet on IBS, exploringvarious dietary approaches to managing IBS, including the low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diet, gluten-free diet, Mediterranean diet, and tritordeum-based diet. It presents evidence from both experimental and observational studies and summarises the underlying dietary triggers in IBS, including gut microbiota dysbiosis, visceral hypersensitivity, and immune activation. In addition, it explores the efficacy and limitations of the key diet and lifestyle recommendations provided by dietary guidelines and scientific literature, highlighting the importance of individualised dietary strategies tailored to the unique needs of different types of IBS patients. By elucidating the complex interplay between diet and IBS pathophysiology, this review provides valuable insights into optimising dietary management approaches for improving symptom control and enhancing the quality of life for individuals with IBS.

Dietary intake and visceral adiposity in older adults: The Multiethnic Cohort Adiposity Phenotype study.

There are established links between the accumulation of body fat as visceral adipose tissue (VAT) and the risk of developing obesity-associated metabolic disease. Previous studies have suggested that levels of intake of specific foods and nutrients are associated with VAT accumulation after accounting for total energy intake. This study assessed associations between a priori selected dietary factors on VAT quantified using abdominal magnetic resonance imaging. The cross-sectional Multiethnic Cohort Adiposity Phenotype Study included n=395 White, n=274 Black, n=269 Native Hawaiian, n=425 Japanese American and n=358 Latino participants (mean age=69years±3 SD). Participants were enrolled stratified on sex, race, ethnicity and body mass index. General linear models were used to estimate the mean VAT area (cm2) for participants categorized into quartiles based on their dietary intake of selected foods/nutrients adjusting for age, sex, racial and ethnic groups, the total percentage fat from whole-body dual energy X-ray absorptiometry and total energy. There were significant inverse associations with VAT for dietary intake of total vegetables, total fruits (including juice), cereals, whole grains, calcium, copper and dietary fiber (p-trend ≤0.04). Positive trends were observed for VAT for participants who reported higher intake of potatoes, total fat and saturated fatty acids (SFA) (p-trend ≤0.02). Foods/nutrients that met the multiple testing significance threshold were total fruits, whole grains, copper, dietary fiber and SFA intake. These results highlight foods and nutrients including SFA, total fruit, whole grains, fiber and copper as potential candidates for future research to inform dietary guidelines for the prevention of chronic disease among older adults.

Association between dietary nutrient intake and prevalence of myopia in Korean adolescents: evidence from the 7th Korea National Health and Nutrition Examination Survey.

The rise in myopia prevalence, particularly among adolescents in East Asia, is a cause for concern. While a combination of environmental and genetic factors is understood to contribute to this trend, the role of dietary nutrients is not yet fully clarified. To assess the potential association between the intake of specific nutrients and the prevalence of myopia in a large, population-based sample of Korean adolescents. Data from 18,077 adolescents (average age: 15.05 ± 1.67 years; 51.7% male, 48.3% female) who participated in the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII, 2016) were analyzed. Refractive error was measured using an auto-refractor-keratometer (KR-8800) without cycloplegia. Dietary intake of 14 nutrients was assessed through a 24-h personalized dietary recall method. The study revealed a myopia prevalence of 87.6% among the adolescents. Multivariable models adjusted for age, gender, BMI, and other confounding factors indicated that higher intakes of carbohydrates, proteins, cholesterol, sodium, and vitamin B2 were associated with an increased risk of myopia. Conversely, higher intake of vitamin C was found to be associated with a decreased risk. The findings suggested a potential association between dietary nutrient intake and myopia prevalence in Korean adolescents. While the study did not establish a causal link, the differences in nutrient intake between the myopic and non-myopic groups could indicate that diet plays a role in the development or progression of myopia. Further research is warranted to corroborate these findings and explore the underlying mechanisms.

Adherence to Dietary Recommendations in Organized Living Beneficiaries with Severe Mental Disorders and Their Caregivers.

People with severe mental disorders often require special care. Other than institutionalized care, some organizations provide housing options and special care in the form of organized living. Few studies provide a detailed description of nutrient intake in this type of care. The aim of this prospective study was to assess nutritional status and adherence to dietary recommendations in both people with mental disorders (beneficiaries) and their caregivers. Across three levels of care, 46 beneficiaries and 19 caregivers participated in the study. The mean intakes of energy (kcal/day) and macro- and micronutrients (g/day) were estimated from a 3-day dietary record and compared with dietary reference values (DRVs) set by the European Food Safety Authority (EFSA). The majority of participants did not meet energy intake recommendations (kcal/day). The contribution of total fat to energy intake (% E) was higher than recommended in both beneficiaries and caregivers with 42.1 ± 4.4% and 38.5 ± 6.5%, respectively. A total of 45.2% of beneficiaries and 61.1% of caregivers had their carbohydrate intake within the recommended range. Fiber intake was well below the recommendations (25 g/day) in all groups. Across all levels of care, lower micronutrient intake for pantothenic acid, biotin, folate, potassium, magnesium, copper, selenium, and iodine was observed. Based on the current results, the development and implementation of nutritional guidelines may be targeted to specific populations and nutrient intakes.

The Food Consumption Pattern of Adolescents in Ibadan

Dietary behaviours of adolescents drive the development of chronic non-communicable diseases later in life. A semi-structured questionnaire was used to obtain information from 800 students at 9 schools in Ibadan, Nigeria and a 74-item food frequency questionnaire was used to assess the frequency of intake of specific foods. Roots and tubers and cereals and legumes were the most commonly consumed food groups. Daily intake of the most commonly consumed fruits was reported by 26.5% (tangerine), 28.0% (pawpaw) and 37.8% (orange). 40.9% reported daily consumption of tomato. 43.2% and 41.8% respectively consumed carbonated drinks and chocolate-flavoured drinks daily. There is a need for the promotion of healthier food choices in these schools.

An Exploration of Dietary Strategies for Hypertension Management: A Narrative Review.

This review aims to clarify the influence of various nutritional approaches in the management of hypertension.An extensive search of databases, namely, PubMed, Cochrane Library, Scopus, and Web of Science, was performed, covering the period from January 2012 to October 2023. We used keywords, such as "hypertension,""nutrition,""nutritional management,""nutrient intake,""dietary strategies,""DASH diet,""Mediterranean diet,"and related terms.Hypertension, a grave global health concern, affects more than one billion people worldwide. Lifestyle modifications, including nutritional strategies, are important in non-pharmacological interventions. Dietary patterns, such as the DASH (DietaryApproaches to Stop Hypertension) and Mediterranean diets, which emphasize fruit and vegetable consumption, have demonstrated efficacy in reducing blood pressure. Certain nutrients, such as potassium, calcium, and magnesium, have significant effects on blood pressure. The mechanisms underlying these dietary strategies include vasodilation, improvement in endothelial function, regulation of sodium balance, and mitigation of oxidative stress. However, successful implementation of these strategies can be hindered by various factors, such as adherence challenges, socioeconomic disparities, and cultural preferences. In conclusion, robust evidence supports the effectiveness of nutritional strategies in the management of hypertension. DASH and Mediterranean diets, along with an increased intake of specific nutrients, contribute to blood pressure reduction. Hence, comprehensive lifestyle modifications, with a focus on nutritional changes, are recommended as primary or complementary treatments for hypertension. Addressing the identified barriers could enhance the efficacy and use of these dietary approaches in clinical practice.

Association between nutrient intake from vegetables and BMI category of in-school adolescents in urban and rural areas in Davao City, Philippines.

Consumption of vegetables may contribute to alleviating the double burden of malnutrition, which is widespread among adolescents. However, the link between specific nutrient intakes from vegetables and the body mass index (BMI) of in-school adolescents is not widely studied. This study determined the association between the nutrient intakes from the vegetables consumed and the BMI category of in-school adolescents in urban and rural areas in Davao City, Philippines. Self-reported vegetable consumption was collected from the respondents, and the corresponding nutrient intakes were calculated using the USDA food composition tables. The BMI of the participating adolescents was also measured. The results show that being underweight or overweight is generally associated with lower macronutrient and micronutrient intakes from the vegetables consumed, namely, bell pepper, bitter gourd, cabbage, carrot, chayote, Chinese cabbage, cucumber, eggplant, Malabar spinach, moringa, mung bean, okra, potato, sponge gourd, squash, string beans, sweet potato, sweet potato tops, taro, tomato, water spinach (P<0.05). The nutrient intakes from vegetables consumed by adolescents from urban households were generally higher. The findings highlight the contribution of vegetables to the nutrient intakes in the adolescent population. This study reinforces the need for targeted dietary guidelines and further promotion of vegetables, especially indigenous ones, to improve the nutritional status of adolescents in the Philippines.
