Consumption Of Whole Grains Research Articles

Grain, Gluten, and Dietary Fiber Intake Influence Gut Microbial Diversity: Data from the Food and Microbiome Longitudinal Investigation.

Regular consumption of whole grains and dietary fiber was associated with greater abundance of gut bacteria that may lower risk of colorectal cancer. Further research on the association of refined grains and gluten with gut microbial composition is needed to understand their roles in health and disease.

Prevalence of non-alcoholic fatty liver disease and its association with lifestyle habits in adults in Chile: a cross-sectional study from the National Health Survey 2016-2017.

Non-alcoholic fatty liver disease (NAFLD) represents an excessive fat accumulation within the liver, usually associated with excess body weight. A liver biopsy is the gold standard for diagnosis, but it is inapplicable in population-based studies. In large populations, non-invasive methods could be used, which may also serve to identify potential protective factors. We aimed to (a) estimate NAFLD prevalence in the adult population in Chile by using non-invasive methods and (b) determine the association between the presence of NAFLD and lifestyle habits. The National Health Survey of Chile 2016–2017 was analysed. We included individuals aged 21–75 years, without infectious diseases nor risky alcohol consumption. NAFLD was detected by either fatty liver index (FLI; considers circulating TAG, circulating γ-glutamyl-transferase, BMI and waist circumference), lipid accumulation product (LAP; considers sex, circulating TAG and waist circumference) or their combination. Lifestyle habits were determined by questionnaires. We included 2774 participants, representative of 10599094 (9831644, 11366544) adults in Chile. NAFLD prevalence (95 % CI) was 39·4 % (36·2, 42·8) by FLI, 27·2 % (24·2, 30·4) by LAP and 23·5 % (20·7, 26·5) by their combination. The prevalence progressively increased with increasing BMI. Of note, less smoking and more moderate-vigorous physical activity and whole-grain consumption were associated with lower odds of having NAFLD, independently of BMI. At least one out of four adults in Chile is afflicted with NAFLD. Health promotion strategies focused on controlling excess body weight and promoting specific lifestyle habits are urgently required.

Nutritional Interventions and Lifestyle Changing in Gestational Diabetes Mellitus Prevention: A Narrative Review

Background: Gestational diabetes mellitus (GDM) is the most common pregnancy complication, and its prevalence is increasing, as obesity is more prevalent in women at reproductive age. Food choices and patterns that might reduce incidence are of great importance, and the present review aims to offer a perspective on different types of nutritional interventions in GDM prevention. Methods: A literature review in the PubMed database was conducted in order to identify full-text, English, randomized control trials and observational clinical studies, published in the last 10 years, that are the most relevant to emphasize the usefulness of nutritional and lifestyle interventions in prevention of GDM. Results and discussions: Twenty-two articles met the inclusion criteria and were relevant for the search. Their outcomes were reported and analyzed. Dietary interventions were very heterogeneous, including general counselling of healthier eating patterns, recommendations to follow a Mediterranean dietary pattern or to choose low-glycemic-index foods, and dietary advice focusing on increasing consumption of some food groups or vitamin D or probiotics supplementations. Conclusions: Among these interventions, a moderate-intensity lifestyle intervention optimizing participants’ consumption of whole grains, vegetables, and fruits; portion control; lowering intake of ultra-processed food and simple sugars; and Mediterranean diet intervention were the most successful in reducing GDM incidence.

Adding Walnuts to the Usual Diet Can Improve Diet Quality in the United States: Diet Modeling Study Based on NHANES 2015-2018.

The under-consumption of calcium, potassium, fiber, and vitamin D is considered a U.S. public health concern. Shifts in eating patterns that increase the consumption of vegetables, fruits, whole grains, nuts/seeds, and dairy products can help achieve the recommended intakes of these nutrients, leading to healthier diets. We assessed the impact of adding 1 ounce (28.35 g) of walnuts to usual diets on diet quality and nutrients of concern, including magnesium, fiber, and potassium. We utilized 24 h dietary recalls obtained from the What We Eat in America, National Health and Nutrition Examination Survey (NHANES) and modeled the addition of 1 ounce (28.35 g) of walnuts to the usual diets of no-nut consumers. No-nut consumers aged ≥4 years (n = 7757) from the 2015-2018 NHANES study were included. Population percentages with intakes below the estimated average requirement (EAR) values for calcium, magnesium, folate, and vitamin E and above the adequate intake (AI) values for potassium and fiber were examined. Diet quality was assessed using the Healthy Eating Index-2015 (HEI-2015). The National Cancer Institute method was used to estimate the usual and modeled intakes. Significant differences between usual (current) and modeled intakes were determined using non-overlapping 95% confidence intervals. All analyses included sample weights to account for the NHANES survey design. Adding 1 ounce (28.35 g) of walnuts to the usual diet resulted in significant reductions in the percentages of adults with intakes below the EAR for magnesium and folate (69.6% vs. 52.0%; 49.2% vs. 40.6%, respectively), and increased the percentage of adults above the AI for potassium (22.8% vs. 26.5%). A similar trend was observed among children (4-18 years). HEI scores improved significantly from 49.1 (95% CI: 48.0-50.4) to 58.5 (95% CI: 57.5-59.6) in children and from 52.4 (95% CI: 51.0-53.8) to 59.2 (95% CI: 58.0-60.5) in adults. Adding 1 ounce (28.35 g) of walnuts to the usual diet of no-nut consumers improved the diet quality and adequacy of some under-consumed nutrients.

Association between whole-grain intake and myopia in chinese children: a cross-sectional epidemiological study

BackgroundNutritional status influences the growth and development of the eyes. However, there are few studies on the association between diet, especially whole grains (WG) consumption, and myopia. The study aimed to evaluate the association between WG intake and myopia prevalence among primary school-age children in China.MethodsThis cross-sectional epidemiological study conducted between November 2019 and December 2019 included 586 children, aged 6–12 years, attending primary school in Binhai district, Tianjin, China. Ophthalmologic examinations and optometric cycloplegic refraction measurements were conducted. Information was collected on known risks and protective factors for myopia and the consumption of WGs, vegetables, and fruits. This association between the probability of myopia and the proportion of WG consumption (WG proportion was calculated as the mean intake from WG sources divided by total grain intake), adjusted for protective and risk factors, was analysed using crude and multivariable logistic regression.ResultsAmong the study participants, 226/586 (38.57%) children had myopia in at least one eye. WG intake was inversely correlated with the prevalence of myopia. Furthermore, in the multivariate analysis, WG intake of > 50% was identified as a protective factor against myopia after subsequent adjustment for children’s age, sex, parental myopia, near-work activity, screen time, reading and writing habits, visual fatigue, outdoor time, and classroom light environment (all P < 0.05).ConclusionWG intake (> 50%) was an independent protective factor against myopia. Modifying the form of grains consumed (whole versus refined) could be one of the targets of future public health measures.

Association between whole-grain consumption and carotid atherosclerosis: the Tianjin chronic low-grade systemic inflammation and health (TCLSIH) cohort study.

Background: Whole-grain contains a range of beneficial nutrients, which are thought to play a role in the prevention of chronic diseases. However, the association between whole-grain consumption and the risk of developing carotid atherosclerosis (CA) has not been sufficiently elucidated. We, therefore, conducted this study to investigate the relationship between whole-grain consumption and CA in the general adult population. Methods: This prospective cohort study included a total of 2166 participants (19.2-84.6 years, 55.0% men) without a history of cardiovascular disease, cancer, and CA at baseline. A validated food frequency questionnaire was used to assess whole-grain consumption. Measurements of CA include carotid intima-media thickness (IMT) and carotid plaque. IMT thickening is defined as: IMT ≥ 1.0 mm or a carotid bifurcation IMT ≥ 1.2 mm. Carotid plaque is defined as: distinct area protruding ≥1.5 mm into the vascular lumen of the carotid artery. Cox proportional hazards regression models were used to examine the association of whole-grain consumption with incident CA. Results: A total of 538 (341 men) first incident cases of CA occurred during 5585 person-years of follow-up (median follow-up: 4.2 years). After adjusting for demographic characteristics, lifestyle factors, dietary intake, individual and family history of disease, the multivariable HRs (95% CIs) for incident CA were 1.00 (reference) for <1 time per week, 1.10 (0.85, 1.43) for 1 time per week, 0.95 (0.75, 1.20) for 2-6 times per week, and 1.12 (0.80, 1.56) for ≥1 times per day, respectively (P for trend = 0.99). Similar results were observed in stratified analyses by the main covariates and sensitivity analyses. Conclusion: Our data indicate that whole-grain consumption had no significant association with the risk of CA in an adult Chinese population. In our study population, there is a low consumption of whole-grain, which may limit our ability to see an association. Further cohort studies or randomized controlled trials are needed to confirm our results.

PS-P09-9: DIETARY PATTERNS AND HYPERTENSION AMONG STROKE-FREE AFRICANS IN THE SIREN STUDY

Objective: This study assessed the relationship of dietary patterns (derived from the frequency of food consumption) with hypertension among stroke-free controls recruited from Nigeria and Ghana in the Stroke Investigation Research and Educational Network (SIREN) study. Design and Methods: This study was a matched case-control study with 1500 hypertensives randomly selected and matched for the country of residence, age and sex with 1500 normotensives in the SIREN study. Factor analysis using principal component analysis was used to summarise food information and seven dietary patterns (DP); vegetables, poultry product and organ meat, whole-grain and fruit drinks, fried foods and sweetened drinks, red meat, processed foods and fruits were identified. Hypertension was defined as one of the following conditions; systolic blood pressure of 140mmHg/greater or diastolic blood pressure of 90mmHg/greater or previous diagnosis or use of antihypertensive medications. Multivariable adjusted logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (CI) for hypertension by the median of factors scores in each DP (adjusting for age, education, income, smoking, alcohol use, physical inactivity, family history of cardiovascular diseases and obesity) at a two-sided P &lt; 0.05. Results: Mean age was 56.2 ± 13.5years and multivariable-adjusted OR (95%CI) for odds of hypertension by the median (with &lt; median of factor score as reference) of DPs revealed higher consumption of whole grains and fruit drinks; 0.83 (0.73, 0.96; P = 0.01) was associated with lower odds of hypertension, but higher consumption of processed foods; 1.18 (1.00, 1.40; P = 0.04) was associated with higher odds of hypertension. Furthermore, multivariable-adjusted OR (95%CI) of hypertension for other DPs include; 0.88 (0.74, 1.04; P = 0.13) for vegetables; 0.89 (0.75, 1.05; P = 0.16) for poultry product and organ meat; 0.90 (0.76, 1.06; P = 0.21) for fruits; 0.90 (0.77, 1.07; P = 0.23) for fried foods and sweetened drinks and 1.03 (0.87, 1.21; P = 0.76) for red meat. Conclusion: Diet rich in whole grains was associated with lower hypertension risk, but higher consumption of processed foods was related to a deleterious hypertension risk. Also, higher consumption of plant-based diets presented a suggestive inverse relationship with hypertension, but diets dense with red meat presented a suggestive deleterious hypertension risk.

Adherence to the Mediterranean diet and depression, anxiety, and stress symptoms in Chilean university students: a cross-sectional study.

This study aims to determine the association of adherence to the Mediterranean diet and its food groups with depressive symptoms in Chilean university students. The study design was cross-sectional. A total of 934 first-year students at a Chilean public university completed a self-report questionnaire. To assess adherence to Mediterranean diet, an index validated in Chile (Chilean-MDI) was used, and depression, anxiety, and stress symptoms were assessed using the Depression Anxiety and Stress Scale (DASS-21). Logistic regression models were used to analyze the association of adherence to Mediterranean diet and its food groups with depression, anxiety, and stress symptoms adjusted for the main confounders. Students with moderate and high adherence to Mediterranean diet showed lower odds of depression [DASS-21 > 5, odds ratio (OR) = 0.64; 95% confidence interval (95%CI): 0.47-0.88] than those with low adherence to Mediterranean diet. The consumption of 1-2 servings/day of vegetables (OR = 0.63; 95%CI: 0.43-0.92), > 2 servings/week of nuts (OR = 0.41; 95%CI: 0.21-0.80), 1-2 servings/day of fruits (OR = 0.60; 95%CI: 0.42-0.85), 1-2 servings/week of fish and seafood (OR = 0.67; 95%CI: 0.48-0.94), and 1/2-3 units/week of avocado (OR = 0.67; 95%CI: 0.48-0.93) showed low odds of depressive symptoms. The consumption of whole grains and cereals (> 2 servings/day) (OR = 1.63; 95%CI: 1.02-2.61) showed the opposite association. Adherence to Mediterranean diet and consumption of fruits, vegetables, nuts, avocado, fish, and seafood are associated with a lower likelihood of depression in Chilean university students. New policies and educational strategies are recommended to improve diet quality and the mental health of the entire university community.

The effects of wholegrain processing on appetite: randomised crossover trial in adults with type 2 diabetes.

Aims: Recent observational data indicate higher ultra-processed food intakes are associated with a broad range of adverse health outcomes. Experimental studies on why this might be are lacking. We have considered the effects of wholegrain processing on measures of appetite in free-living adults with type 2 diabetes. Materials and methods: Participants were randomised to two interventions of two-weeks duration, separated by washout. Interventions were nutrient-matched wholegrain foods that differed by the amount of processing. Self-reported hunger and satiety were indicated on visual analogue scales before or after meals for four days at baseline and the end of each intervention. Metabolite markers of appetite were measured pre and post intervention in fasting plasma. Results: 31 adults (63 ± 13 years old, BMI 32.4 ± 7, HbA1c 7.5 ± 3.4% (59 ± 14 mmol mol-1)) commenced the trial, 28 (90%) completed both interventions. Wholegrain consumption, as measured by alkylresorcinols, was balanced between interventions. Self-reported pre-meal hunger was consistently lower at breakfast (MD, mean difference 0.49/10 95% CI 0.03 to 0.94), lunch (MD 0.67/10 95% CI 0.09 to 1.25), and dinner (MD -0.71/10 95% CI 0.19 to 1.23) during the intervention of less processed whole grains when compared with pre-intervention measures, however this did not result in a difference between interventions. Change in metabolite markers of appetite did not differ between interventions. Conclusions: A significant difference in hunger or satiety between less and more processed whole grains over intervention periods of two weeks was not detected within the current trial. Further experimental studies are needed to consider the potential effects of food processing on physiological processes such as appetite to provide mechanistic understanding behind observations of highly processed food intakes and adverse health outcomes.

Diagnosis and treatment of hepatic lipidosis in a 42-year-old gray parrot: A case report

The African grey parrot (Psittacus erithacus) is among the world's most well-known seed-eating cage birds. A grain-eating diet has been reported to cause liver lipidosis in parrots. Fatty liver syndrome occurs when the liver cannot metabolize and re-secrete processed fatty acids due to excessive dietary fatty acids or lipolysis. The present study involves a 42-year-old African grey parrot with extensive feather pecking in the neck, legs, and chest areas, red color changes in the feathers on the legs, and lethargy. The patient's medical history includes the consumption of sugar, chocolate, and whole grains, which is the main reason for metabolic disorders. A comprehensive evaluation of serum biochemistry, total protein levels, aspartate aminotransferase (AST), creatine kinase (CK), triglycerides, and uric acid was conducted on the first visit. Following two weeks of treatment, the bird was again referred to the clinic for clinical pathological evaluation and diagnostic imaging. Different liver medicines, such as herbal antioxidants, vitamins, and amino acid supplements, are prescribed during the treatment process. In addition, the bird's diet was modified. Following the diet and treatment, the blood parameters reached normal limits. The echogenicity of liver tissue was close to normal after the initial observation of feathers regrowing in some areas, as well as blood sample evaluation. A paraclinical test was taken on the bird again after two months of treatment to ensure the disease did not recur. Diligent care, nutritional support, veterinary monitoring, and appropriate medications can improve hepatic lipidosis, but permanent damage may occur. Therefore, it is very critical to quickly diagnose and prevent the recurrence of the illness.

Potential Therapeutic Effect of Barley on Cardiovascular Diseases

Barley is a fantastic food option for those with various illnesses as well as for those who want to lead a healthy lifestyle. This cereal is a great source of soluble dietary fiber, particularly beta glucans, and it also includes vital vitamins and minerals. For its excellent antioxidant activity and as a source of vitamins and minerals, green barley is advised. Depending on phytonutrients such as -glucan, phenolics, flavonoid, lignans, tocols, sitosterol, and folic, regular consumption of whole wheat grain and its hydroethanolic extracts decreases the risk of chronic ailments (hyperglycemia, malignancy, overweight, cardiac disease. Barley and its products in a recent year had gain an importance due to its counteractive components which play potent role against cardiovascular diseases by lowering down the oxidative stress and improving High density lipoprotein further Lowering down low-density lipoprotein, VLDL ratios further regulating insulin levels and lowering down the spike in blood glucose levels showing potent anti-oxidative and cardiovascular functions. Due to their abundance in these nutrients, barley is effective in promoting healthy bodily function. To enjoy all of the advantages of barley, barley grain is a wonderful option.

Ultra-processed foods consumption and diet quality among preschool children and women of reproductive age from Argentina.

To assess the association between the consumption of ultra-processed foods (UPF) and diet quality among preschool children and women of reproductive age from Argentina. Cross-sectional and nationally representative survey. The food items were classified according to the NOVA system. Consumption of fruits, vegetables, legumes, nuts, seeds and wholegrains was estimated, and the energy and nutrients related to non-communicable disease (NCD) intake. Linear regression was used to assess the associations. Argentina. Children aged 2-5 years (n 7022), female adolescent aged 10-19 years (n 2165) and women aged 20-49 years (n 4414). UPF represented more than a quarter of total energy intake, 27 % in children, 31 % in female adolescents and 26 % in women. Across all age groups, the major contributors to UPF consumption were cookies and pastries (about 6·0-7·0 %), soft drinks (about 2·7-3·7 %), candies (about 1·8-4·6 %), and juices (about 1·3-1·7 %). The consumption of fresh vegetables, fresh fruits and legumes was negatively associated with UPF consumption. A significant positive association was found between the dietary share of UPF and the dietary content of NCD-promoting nutrients such as free sugars and total saturated and trans-fats. In contrast, a significant negative association was found with the content of NCD-protective such as fibre and protein. UPF were associated with lower consumption of healthy foods and higher intake of nutrients related to NCD in children and women of reproductive age in Argentina. It is necessary to design food policies that simultaneously reduce the consumption of UPF while promoting the intake of fresh and whole foods to improve the dietary quality.

Consumption of whole grains and refined grains and associated risk of cardiovascular disease events and all-cause mortality: a systematic review and dose-response meta-analysis of prospective cohort studies

BackgroundAlthough relationships between the intake of whole grains and refined grains and the incidence of cardiovascular disease (CVD) events and all-cause mortality have been investigated, the conclusions have been inconclusive. ObjectivesWe aimed to comprehensively summarize the evidence about the correlation between consuming whole grains and refined grains and risks of CVD events and all-cause mortality and to evaluate the meta-evidence quality. MethodsWe searched PubMed, Embase, and Web of Science until 15 March, 2022. Random-effects models were employed to calculate summary relative risks (RRs) and 95% confidence intervals (CIs). We explored potential linear or nonlinear relationships using restricted cubic splines. The NutriGrade tool was employed to rate meta-evidence quality. ResultsTwenty-four articles (68 studies; 46 for whole grains and 22 for refined grains) with 1,624,407 participants were included. Per 30-g increase in daily whole grain consumption, the RRs and 95% CIs of stroke, coronary heart disease (CHD), heart failure (HF), CVD, and all-cause mortality were 0.98 (0.96, 1.00), 0.94 (0.92, 0.97), 0.97 (0.89, 1.07), 0.92 (0.88, 0.96), and 0.94 (0.92, 0.97), respectively. Whole grain consumption was linearly associated with CHD (Pnonlinearity = 0.231) and nonlinearly associated with CVD (Pnonlinearity = 0.002) and all-cause mortality (Pnonlinearity = 0.001). Except for a positive correlation between refined grain consumption and all-cause mortality in the restricted cubic spline, no significant influence of refined grain intake on stroke, CHD, HF, and CVD was detected. The meta-evidence quality for the association of whole grain consumption with stroke, CHD, HF, CVD, and all-cause mortality was moderate, moderate, low, high, and high, respectively. For refined grains, all meta-evidence was of low quality. ConclusionsConsuming whole grains, rather than refined grains, can assist in preventing CHD, CVD, and all-cause mortality. Relationships between consumption of refined grains and health outcomes should be interpreted cautiously because of the low quality of meta-evidence.

Effectiveness of a Teaching Kitchen Intervention on Dietary Intake, Cooking Self-Efficacy, and Psychosocial Health

ABSTRACT Background The consumption of fruits, vegetables, and whole grains (FVWG) has been associated with decreased risk of chronic disease, yet over 80% of U.S. adults do not meet dietary recommendations for FVWG. Purpose This study explored the effectiveness of a teaching kitchen intervention upon consumption of FVWG and overall dietary patterns. Cooking self-efficacy, comfort in the kitchen, and elements of psychosocial health were also assessed. Methods Participants were recruited to the 5-week Complete Health Improvement Program–Teaching Kitchen (CHIP-TK) through a worksite wellness initiative. The program, based upon elements of the social cognitive theory, included cooking classes, health education, and horticulture activities. Pre- and post-surveys were administered and evaluated. Results CHIP-TK led to significant increases in FVWG intake. Cooking self-efficacy, comfort in the kitchen, and general well-being scores also improved, with medium-to-large effect sizes. Participant feedback indicated weekly meetings, hands-on cooking classes, facilitator expertise, and group camaraderie were keys to success in the program. Discussion Teaching kitchens are well-received within a worksite setting and have the potential to improve dietary intake patterns and psychosocial health.Translation to Health Education Practice: Health educators should design and implement integrative, theory-driven programs to improve nutritional status, well-being, and overall health.

Prevalence and risk factors of belching disorders: A cross-sectional study among freshman college students.

Belching disorders seriously affect quality of life; however, their prevalences and risk factors remain unknown. The aim of our study was to determine the prevalence and risk factors, particularly lifestyle factors, of belching disorders among freshman college students in central China. A cross-sectional study was conducted in September 2019 in Huazhong University of Science and Technology (Wuhan, Hubei Province, China). The subjects were asked to complete a self-administered questionnaire for data collection, including sociodemographic information, lifestyle factors, and gastrointestinal symptoms. Belching disorder was diagnosed based on the Rome IV criteria. Univariate and multivariate logistic regression analyses were performed to determine the risk factors for belching disorders. A total of 3335 subjects were enrolled, and 78.26% were men. Among them, 1.95% (65/3335) reported belching disorders. Significant differences in the Pittsburgh Sleep Quality Index (PSQI), Student-Life Stress Inventory (SLSI) scores, and consumption of whole grains, black tea, coffee were found between the belching and non-belching groups. Multivariate logistic regression analysis showed that coffee consumption at least once weekly and a high total SLSI score (over mean + standard deviation) were independent risk factors for belching disorders, while intake of whole grains at least once weekly was a protective factor. Excessive belching is a common disorder among freshman college students in central China. Lifestyle factors, including consumption of whole grains and coffee, and stress, were associated with belching disorders. Therefore, dietary intervention may be a potential management for belching disorders.

Nutritionally adequate and environmentally respectful diets are possible for different diet groups: an optimized study from the NutriNet-Santé cohort

Research has shown that vegetarian diets have a low environmental impact, but few studies have examined the environmental impacts and nutritional adequacy of these diets together, even though vegetarian diets can lead to nutritional issues. Our objective was to optimize and compare 6 types of diets with varying degrees of plant foods (lacto-, ovolacto-, and pescovegetarian diets and diets with low, medium, and high meat content) under nutritional constraints. Consumption data in 30,000 participants were derived from the French NutriNet-Santé cohort using an FFQ. Diets were optimized by a nonlinear algorithm minimizing the diet deviation while meeting multiple constraints at both the individual and population levels: nonincrease of the cost and environmental impacts (as partial ReCiPe accounting for greenhouse gas emissions, cumulative energy demand, and land occupation, distinguishing production methods: organic and conventional), under epidemiologic, nutritional (based on nutrient reference values), and acceptability (according to the diet type) constraints. Optimized diets were successfully identified for each diet type, except that it was impossible to meet the EPA (20:5n-3) + DHA (22:6n-3) requirements in lacto- and ovolactovegetarians. In all cases, meat consumption was redistributed or reduced and the consumption of legumes (including soy-based products), whole grains, and vegetables were increased, whereas some food groups, such as potatoes, fruit juices, and alcoholic beverages, were entirely removed from the diets. The lower environmental impacts (as well as individual indicators) observed for vegetarians could be attained even when nutritional references were reached except for long-chain n-3 (omega-3) fatty acids. A low-meat diet could be considered as a target for the general population in the context of sustainable transitions, although all diets tested can be overall nutritionally adequate (except for n-3 fatty acids) when planned appropriately.This trial was registered at clinicaltrials.gov as NCT03335644.

Evaluation of rural-urban patterns in dietary intake: A descriptive analytical study - Case series.

This article aimed to evaluate the different epidemiological aspects of the population (Fez-Meknes region), expose the secular trends of the food habits related to it, present the basic concepts and mechanisms of food in urban and rural areas in the Fez-Meknes region, and finally to analyze the results in the light of a literature review. A survey was conducted among a representative sample of the urban and rural population in the Fez-Meknes region (654 people aged 15 years and over, of which 326 people reside in the urban commune of Fez and 328 in the rural commune of Loulja in the province of Taounate). The results are, a difference between the two urban and rural groups concerning the rhythm of taking meals outside the home (P<0,001); the average frequency of consumption of certain foods according to social class (p<0,001); the frequency of food consumption per week of legumes, olive oil, fermented milk, and tea is more increased than that recorded in the urban environment (p<0,001). On the other hand, the quantification of the consumption of sweet products, dairy products, and whole grains did not conclude a significant difference between the two study environments (p>0,05). Changing dietary patterns over the past few decades, including more shift work, more meals eaten outside the home or family setting, and more irregular eating patterns, including skipping breakfast and eating late at night. A disparity in eating habits between urban and rural areas was noted. It would be necessary to act judiciously on the environmental factors by encouraging the Moroccan populations to maintain, as much as possible, their good traditional habits, and to reinforce the new good food habits.

Comparative effectiveness of single foods and food groups on body weight: a systematic review and network meta-analysis of 152 randomized controlled trials.

This study aimed at quantifying and ranking the effects of different foods or food groups on weight loss. We searched PubMed, Scopus, Cochrane Central Register of Controlled Trials, and Embase to April 2021. We included randomized trials evaluating the comparative effects of two or more food groups, or compared a food group against a control group (usual diet, no intervention) for weight loss in adults. We conducted random-effects network meta-analysis with Bayesian framework to estimate mean difference [MD] and 95% credible interval [CrI] of the effect of food groups on weight loss. 152 RCTs with 9669 participants were eligible. Increased consumption of fish (MD -0.85kg, 95% CrI -1.66, -0.02; GRADE = low), whole grains (MD -0.44kg, 95% CrI -0.88, 0.0; GRADE = very low), and nuts (MD -0.37kg, 95% CI -0.72, -0.01; GRADE = low) demonstrated trivial weight loss, well below minimal clinically important threshold (3.9kg), when compared with the control group. Interventions with other food groups led to no weight loss when compared with either the control group or other food groups. The certainty of the evidence was rated low to very low with the point estimates for all comparisons less than 1kg. None of the food groups showed an important reduction in body weight when restricted to studies conducted in participants with overweight or obesity. Interventions with a single food or food group resulted in no or trivial weight loss, especially in individuals withoverweightor obesity. Further trials on single foods or food groups for weight loss should be highly discouraged.

Mobile Digital Health Intervention to Promote Nutrition and Physical Activity Behaviors Among Long-term Unemployed in Rural Areas: Protocol for a Randomized Controlled Trial.

Long-term unemployed have poor nutritional and physical activity statuses, and, therefore, special health promotion needs. Particularly in rural areas, however, they often do not have access to health promotion service. Thus, new promising strategies to improve the health of long-term unemployed are needed. Hence, a digital health intervention to promote nutritional and physical health behaviors was conceived, and the effectiveness of the intervention in combination with face-to-face sessions will be evaluated in a randomized controlled trial. The aim of this study is to elucidate the effectiveness of a mobile digital health intervention to promote the nutritional and physical activity behaviors of long-term unemployed in the rural areas of Germany. The 9-week intervention aims to promote nutritional or physical activity behavior by improving drinking habits, increasing the consumption of fruits, vegetables, and whole grains, increasing daily step count, strengthening muscles, and improving endurance. The intervention design is based on the transtheoretical model and is implemented in a mobile app using the MobileCoach open-source platform. The effectiveness of the intervention will be elucidated by a 9-week, 2-armed, parallel-designed trial. Therefore, long-term unemployed will be recruited by employees of the German social sector institutions and randomized either to receive information brochures; the digital intervention in the form of a mobile app; and 3 face-to-face sessions regarding technical support, healthy eating, and physical activity (n=100) or to receive a control treatment consisting of solely the hand over of information brochures (n=100). The effectiveness of the intervention will be assessed using questionnaires at baseline, after 9 weeks in face-to-face appointments, and after a 3-month follow-up period by postal contact. The use of the mobile app will be monitored, and qualitative interviews or focus groups with the participants will be conducted. Incentives of €50 (US $49.7) will be paid to the participants and are tied to the completion of the questionnaires and not to the use of the mobile app or progress in the intervention. The effectiveness of the intervention in promoting the nutritional and physical activity behaviors of long-term unemployed participants will be elucidated. The adherence of the participants to and the acceptance and usability of the mobile device app will be evaluated. Recruitment started in March 2022, and the final publication of the results is expected in the first half of 2023. Positive health-related changes made by the intervention would display the potency of digital health interventions to promote nutritional and physical activity behaviors among long-term unemployed in the rural areas of Germany, which would also contribute to an improved health status of the German population in general.

Diet and its association with reduced semen quality

Introduction: Infertility is defined as the inability to conceive a child for at least 12 months of regular unprotected intercourse and may affect up to 15% of couples of reproductive age. Reduced semen quality may be caused by trauma, inflammation, or an inappropriate lifestyle. Research suggests that diet may be a factor in influencing sperm parameters.Material and methods: The literature of the PubMed scientific base was searched in 2015-2022 using the following keywords: semen, diet, infertility.Results: Analyzes of eating patterns showed that eating a diet high in red meat, high-fat dairy, sweet energy drinks, and snacks could negatively affect semen, and a pattern based on the consumption of fish, chicken, vegetables, fruits, legumes, and whole grains was associated with with an increased concentration of sperm. A high-fat diet (HFD) leads to obesity, endocrine disorders, dysbiosis of the intestinal microflora, and may be a factor that activates autophagy, which results in reduced sperm quality. A ketogenic diet can positively affect the semen of obese, infertile men. Studies analyzing the Mediterranean diet suggest that higher compliance rates are associated with a higher percentage of mobility as well as a reduced risk of low sperm concentration. The way you prepare your meals can also play a role as glycation end products are produced when grilling, baking and frying, which can damage sperm DNA.Conclusions: Diet may be an important factor influencing the quality of sperm in men, however, there is a need for further extensive, multi-center studies that will systematize this knowledge, which will enable the creation of specific nutritional recommendations for this group of people.
