Developing and testing personalised nutrition feedback for more sustainable healthy diets: the MyPlanetDiet randomised controlled trial protocol.

Agriculture and food production contribute to climate change. There is mounting pressure to transition to diets with less environmental impact while maintaining nutritional adequacy. MyPlanetDiet aimed to reduce diet-related greenhouse gas emissions (GHGE) in a safe, nutritionally adequate, and acceptable manner. This paper describes the trial protocol, development, and testing of personalised nutrition feedback in the MyPlanetDiet randomised controlled trial (RCT). MyPlanetDiet was a 12-week RCT that provided standardised personalised nutrition feedback to participants based on new sustainable healthy eating guidelines (intervention) or existing healthy eating guidelines (control) using decision trees and corresponding feedback messages. To test the personalised nutrition feedback, we modelled a sample of 20 of the MyPlanetDiet participants baseline diets. Diets were modelled to adhere to control and intervention decision trees and feedback messages. Modelled nutrient intakes and environmental metrics were compared using repeated measure one-way analysis of covariance. Intervention diets had significantly lower (p < 0.001) diet-related GHGE per 2500 kilocalories (kcal) (4.7kg CO2-eq) relative to control (6.6kg CO2-eq) and baseline (7.1kg CO2-eq). Modelled control and intervention diets had higher mean daily intakes of macronutrients (carbohydrates, fibre, and protein) and micronutrients (calcium, iron, zinc, and iodine). Modelled control and intervention diets had lower percent energy from fat and saturated fat relative to baseline. Adherence to the MyPlanetDiet personalised nutrition feedback would be expected to lead to better nutrient intakes and reduced diet-related GHGE. The MyPlanetDiet RCT will test the effectiveness and safety of personalised feedback for a more sustainable diet. Clinical trials registration number: NCT05253547, 23 February 2022.

Athletes' nutritional demands: a narrative review of nutritional requirements.

Nutrition serves as the cornerstone of an athlete's life, exerting a profound impact on their performance and overall well-being. To unlock their full potential, athletes must adhere to a well-balanced diet tailored to their specific nutritional needs. This approach not only enables them to achieve optimal performance levels but also facilitates efficient recovery and reduces the risk of injuries. In addition to maintaining a balanced diet, many athletes also embrace the use of nutritional supplements to complement their dietary intake and support their training goals. These supplements cover a wide range of options, addressing nutrient deficiencies, enhancing recovery, promoting muscle synthesis, boosting energy levels, and optimizing performance in their respective sports or activities. The primary objective of this narrative review is to comprehensively explore the diverse nutritional requirements that athletes face to optimize their performance, recovery, and overall well-being. Through a thorough literature search across databases such as PubMed, Google Scholar, and Scopus, we aim to provide evidence-based recommendations and shed light on the optimal daily intakes of carbohydrates, protein, fats, micronutrients, hydration strategies, ergogenic aids, nutritional supplements, and nutrient timing. Furthermore, our aim is to dispel common misconceptions regarding sports nutrition, providing athletes with accurate information and empowering them in their nutritional choices.

L’apport alimentaire en micronutriments dans le trouble du spectre de l’autisme chez des enfants de l’ouest Algérien

Autism Spectrum Disorders (ASD) can affect the nutritional status of children. This study aimed to assess the daily dietary intakes (DDI) of micronutrients, as well as the frequency of consumption (FC) of different food groups, in children with ASD and compare them to those with typical development (TD). It will also determine to what extent these intakes comply with the Recommanded Dietary Allowances (RDA). The study included 52 children, 26 with ASD and 26 with TD. DDI and FC were gathered using a 7-day food diary. Among the DDI of micronutrient, only Vit B12 showed a significant difference between cases and controls, but the DDI was higher than the recommendations in both groups studied. All the children of our study sample had DDI lower than the RDA, in iron, calcium, vitamins E and K1. However, the most notable discrepancy with the recommendations was observed in iron intake (6.95±2.87mg/d vs 7.04±2.98mg/d, p>0.05; RDA equal to 10mg/d) primarily due to low consumption of meat products, and in calcium (406.96mg/d vs 399.46mg/d, p>0.05; RDA of 1000mg/d). Most of the children in this study had a FC of dairy products below the recommended consumption frequency. This study highlights the importance of improving dietary guidance for both groups studied, with particular attention to children with ASD to avoid any complications of ASD.

Micronutrients Importance in Cancer Prevention-Minerals.

Cancer, a non-communicable disease with diverse kinds is one of the major global problems with high incidence and no proven method to prevent or treat. Minerals including trace elements are significant micronutrients for preserving the body's typical physiological function. In contrast to extremely processed industrial food, they are rich in natural sources of food and frequently included in nutritional supplements. The daily intake, storage capacities, and homeostasis of micronutrients depend on specific dietary practices in contemporary civilization and can be disturbed by various malignancies. Varied minerals have different effects on the status of cancer depending on how they affect these pathways. The outcomes could differ depending on the mineral such as calcium's supply and the cancer's location. A mineral called zinc helps the immune system function better and aids in wound healing. On the other hand, selenium exhibits anti-oxidant functions and has a dose-response relationship with many cancer types. However, this component can make the patient's condition worse. Although the body produces free radicals when iron is deficient, anaemia affects a patient's quality of life and ability to receive therapy. This chapter compiles the knowledge of minerals connected to unusual accumulation or depletion states in various malignancies.

Practical application of the Crohn's disease exclusion diet as therapy in an adult Australian population.

There is demand from patients and clinicians to use the Crohn's disease exclusion diet (CDED) with or without partial enteral nutrition (PEN). However, the therapeutic efficacy and nutritional adequacy of this therapy are rudimentary in an adult population. This review examines the evidence for the CDED in adults with active luminal Crohn's disease and aims to provide practical guidance on the use of the CDED in Australian adults. A working group of nine inflammatory bowel disease (IBD) dietitians of DECCAN (Dietitians Crohn's and Colitis Australian Network) and an IBD gastroenterologist was established. A literature review was undertaken to examine (1) clinical indications, (2) monitoring, (3) dietary adequacy, (4) guidance for remission phase, and (5) diet reintroduction after therapy. Each diet phase was compared with Australian reference ranges for food groups and micronutrients. CDED with PEN is nutritionally adequate for adults containing sufficient energy and protein and meeting >80% of the recommended daily intake of key micronutrients. An optimal care pathway for the clinical use of the CDED in an adult population was developed with accompanying consensus statements, clinician toolkit, and patient education brochure. Recommendations for weaning from the CDED to the Australian dietary guidelines were developed. The CDED+PEN provides an alternate partial food-based therapy for remission induction of active luminal Crohn's disease in an adult population. The CDED+PEN should be prioritized over CDED alone and prescribed by a specialist IBD dietitian. DECCAN cautions against using the maintenance diet beyond 12weeks until further evidence becomes available.

Enhancing patient care: Ethical considerations for micronutrient management in hospital nutrition settings

Micronutrients are represented by vitamins and minerals and are present in a wide variety of foods. Each of these nutrients performs specific functions that are essential for the health of our cells and their harmonious functioning. Data suggest that many people have an inadequate daily intake of micronutrients, even when nutritious food is more easily available. It has since been established that the complex, integrated immune system needs multiple specific micronutrients, including vitamins A, D, C, E, B6, and B12, folate, zinc, iron, copper, and selenium, which play vital, often synergistic roles at every stage of the immune response.

Four-week administration of an energy and protein dense oral nutritional supplement improves micronutrient concentrations but does not completely correct deficiencies in institutionalized malnourished older adults.

Poor food intake is common among elderly living in nursing homes, leading to micronutrient deficiency (MD). There are no recommendations for the management of MD in malnourished older adults. We conducted a single arm, open-label, multicenter interventional study in institutionalized malnourished older adults to describe the effect of a 4-week daily energy and protein dense oral nutritional supplementation (ONS, 600 kcal, 30 g protein per unit) containing 50% of the recommended daily micronutrient intake on micronutrient status. Plasma concentrations of vitamins (A, B9, B12, C, E), magnesium (Mg), selenium (Se) and zinc (Zn), and erythrocyte vitamin B9 were measured at baseline and after 4 weeks. Forty-six participants completed the study (age 87.4 ± 6.6). At baseline, the most frequent MD were Se (48%), Zn (35%), Mg (24%) and vitamin C (24%). Plasma concentrations of vitamins B9, B12, C and E, Mg, Se and Zn significantly increased and the proportion of subjects with at least one MD decreased (p = 0.006). However, after 4 weeks, 40% of subjects still had at least one MD. ONS consumption improved micronutrient status but did not correct MD in all participants. Our data suggest that the prescription of vitamin, mineral and trace element supplementation should be considered in institutionalized malnourished older adults in addition to high energy and high protein ONS.

Breakfast Consumption and Quality of Macro- and Micronutrient Intake in Indonesia: A Study from the Indonesian Food Barometer.

Breakfast is an important meal that has been shown to have a positive effect on health. The current study aimed to assess the patterns of breakfast consumption among adult Indonesians and to estimate the contribution of breakfast to their nutrient intake and dietary quality. The study used 24-h recall data from the 2018 Indonesian Food Barometer study to assess breakfast intake among 1333 adults aged 18 and above from six provinces in Indonesia. Diet quality was measured using the Nutrient Rich Food index (NRF) 9.3, and the nutritional profile of breakfast was compared across tertiles of NRF 9.3. In total, 5.2% of adults in Indonesia skipped breakfast. Breakfast contributed 26% to daily energy intakes and 22-28% to intakes of all reported nutrients, except for total sugar (12%), vitamin C (8%) and vitamin D (7%). With respect to daily requirements, breakfast contributed approximately 20% to energy, protein, fat and sodium requirements, 26% to saturated fat but <15% to the requirements for most micronutrients and only 5% for fiber. Among breakfast consumers, a higher NRF score was associated with higher daily intakes of protein, dietary fiber and micronutrients and lower intakes of sodium from breakfast. This study suggests that a balanced breakfast in Indonesia should aim to lower fat and saturated fat intake while increasing fiber, potassium, calcium and vitamin C and D intake. These findings could inform the development of nutrient-based guidelines for breakfast consumption in Indonesia.

The Interplay of Sulfur and Selenium Enabling Variations in Micronutrient Accumulation in Red Spinach.

Aside from its importance in human and animal health, low levels of foliar-applied selenate (SeO4) can be advantageous in the presence of sulfur (S), contributing to improved growth, nutrient uptake, and crop quality. A hydroponic experiment in a growth chamber explored the interactive influence of Se and S on micronutrients and several quality indices, such as soluble sugars, organic acids, and total protein concentrations in spinach (Spinacia oleracea L.). Three levels of S (deprivation, adequate, and excessive) with varying quantities of Se (deficient, moderate, and higher) were examined in combination. Under S starvation and along with S nourishment in plant parts, Se treatments were found to cause noticeable variations in plant biomass and the concentrations of the examined elements and other quality parameters. Both Se levels promoted S accumulation in S-treated plants. Although the Se treatment had the opposite effect in shoots, it had a favorable impact on minerals (apart from Mn) in roots grown under S-limiting conditions. The S and Se relationship highlighted beneficial and/or synergistic effects for Mn and Fe in edible spinach portions. Reducing sugars were synergistically boosted by adequate S and moderate Se levels in roots, while in shoots, they were accumulated under moderate-or-higher Se and excessive S. Furthermore, the concentration of the quantified organic acids under S-deficient conditions was aided by various Se levels. In roots, moderate Se under high S application enhanced both malic acid and citric acid, while in the edible parts, higher Se under both adequate and elevated S levels were found to be advantageous in malic acid accumulation. Moreover, by elevating S levels in plant tissues, total protein concentration increased, whereas both moderate and high Se levels (Se1 and Se2) did not alter total protein accumulation in high S-applied roots and shoots. Our findings show that the high S and medium Se dose together benefit nutrient uptake; additionally, their combinations support soluble sugars and organic acids accumulation, contributing ultimately to the nutritional quality of spinach plants. Moreover, consuming 100 g of fresh red spinach shoot enriched with different Se and S levels can contribute to humans' daily micronutrients intake.

O-046 Nutritional habits might improve your fertility

Abstract Many lifestyle factors have been identified as risk factors for male infertility. For example, an unbalanced diet leading to overweight, obesity, metabolic disorders, and micronutrient deficiencies can have consequences for male reproductive functions. Obese men present more often altered semen parameters and a reduced chance of pregnancy naturally or after medically assisted procreation. In some cases, weight loss can reverse the adverse effects of obesity. However, few interventional studies have demonstrated the effectiveness of a preconceptional intervention in men. In contrast, more and more studies are highlighting the importance of a balanced diet and physical activity to improve fertility. A qualitatively adequate and balanced diet and appropriate daily intake of micronutrients are fundamental for male reproductive functions. Some teams have highlighted the benefits of the Mediterranean diet on sperm production, whereas the Western diet, including reconstituted meats, fried foods, and sweet foods and drinks, was associated with altered semen parameters. However, few interventional studies have confirmed the impact of men's diets on the chances of natural or medically assisted pregnancy and live birth, and their results are controversial. Therefore, robust randomised controlled studies are needed. Practical advice and education can be recommended to men who wish to conceive to help them maintain or achieve the public health recommendations that encourage a balanced diet, such as the Mediterranean diet.

A real-world evidence study evaluating consumer experience of Supradyn Recharge or Supradyn Magnesium and Potassium during demanding periods.

Challenging periods and/or mild micronutrient deficiencies may result in a lack of energy and general fatigue, frequently occurring in the general population. Supradyn Recharge and Supradyn Magnesium and Potassium (Mg/K) are multimineral/vitamin supplements formulated to ensure adequate daily intake of micronutrients. We conducted an observational study addressing consumption behaviour, reasons for intake, frequency of intake, and consumer experiences, satisfaction and characteristics under real-life conditions. This was a retrospective, observational study carried out with two computer-aided web quantitative interviews. A total of 606 respondents (almost equally split between men and women; median age 40 years) completed the questionnaires. The majority indicated having a family, a job and a good level of education; they stated to be long-time and daily users, reporting an average daily intake of 6 days a week. More than 90% of consumers claimed they were satisfied, would use the products again and recommend them; over two-thirds felt the value for money was good. Supradyn Recharge has been mainly used to support lifestyle change and mental resilience, seasonal changes, and post-illness recovery. Supradyn Mg/K has been used to sustain or regain energy levels during hot weather or physical activity and as a support against stress. Users claimed a positive impact on quality of life. Overall, the perception of benefit by consumers was extremely positive as reflected in their consumption behaviour, the majority of whom stated to be long-time users and daily consumers, with an average daily intake of 6 days for both products. These data complement and add up to the results of Supradyn clinical trials.

Nutritional Assessment and Proximate Analysis of Selected Vegetables Grown in Larkana, Sindh, Pakistan

Food security and protection are the most crucial concerns worldwide. However, vegetables may significantly contribute to the macro and micro-nutrients for good health compared to dietary supplements. Eight vegetables of the Larkanadivision, namely spinach (Spinacia oleracea), brinjal (Solanum melongina L.), sponge gourd (Luffa acutangula), lotus root (Lelumbo nucifera), okra (Abelmoschus esculentus), coriander leave (Coriandrum sativum), fenugreek leave (Trigonella foenum graecum), and cauliflower (Brassica oleracea) were studied for their proximate, macro and micro-mineral contents to estimate their importance in human nutrition. The results showed that almost all vegetables contain appreciable amounts of essential nutrients. All the vegetables showed moisture contents of &amp;gt;70.00%. Lotus and sponge gourd have a maximum level of carbohydrates (&amp;gt;10.00%). Fiber was found in the range of 2.70 – 5.10%, with the highest in the okra. Protein and fat were found at &amp;lt; 4.00%, with maximum protein in spinach and fat in fenugreek leaves. The studied vegetables showed maximum levels of K and Ca, followed by Na, Mg, Fe, Zn, and Cu while Cr and Mn were observed to be &amp;lt; 5.00 µg/g. The macro and micro-minerals in the studied vegetables were within the maximum permissible limits recommended by WHO. Moreover, the eight studied vegetables of the Larkana division can also provide up to 1.00% of the required dietary daily intake of macro and micro-nutrients as recommended by the Food and Nutrition Board.

Setting references for daily intake of micronutrients: A study on magnesium

ObjectivesThe Institute of Medicine stratifies the references for daily nutrient intake into age and sex groups, considering that the basal metabolic rate varies according to these aspects, and in most cases, it extrapolates the values calculated for adults to children, because their body weights are different. In this context, this study aimed to evaluate the recommendation for magnesium in children according to energy expenditure. MethodsThis was an observational study using the database of the Social Changes, Asthma and Allergy in Latin America (SCAALA) cohort, which randomly collected information from 1445 children ages 4 to 11 y. Of these, 480 (33%) were part of the present study (children between 7 and 11 y old with eutrophic body mass index and adequate growth). Information on food intake was obtained from the child's parents or legal guardians through a 24-h recall. The population was characterized using static analyses such as the Student t test, Pearson correlation coefficient, and linear regression. ResultsThe mean age of the sample was 8.5 ± 0.96 y, and 54% were males. The mean magnesium intake was 149 ± 70 mg, with a high correlation observed between energy expenditure and magnesium intake (boys: R, 0.716; P <0.001; girls: R, 0.641; P < 0.001). ConclusionsThe metabolic rate can be considered a reference variable for recommending the daily intake of the studied nutrient, aiming to avoid deficiencies and food poisoning because of poor intake.

Macronutrient and Micronutrient Intake in Adolescents With Non-alcoholic Fatty Liver Disease: The Association With Disease Severity.

While dietary changes are recommended to treat pediatric non-alcoholic fatty liver disease (NAFLD), the role of specific nutrients in disease progression is unclear. The objective of this study is to (1) assess the macronutrient and micronutrient intake in adolescents with liver biopsy proven NAFLD [with and without non-alcoholic steatohepatitis (NASH)] and lean controls; (2) determine nutritional predictors of disease severity amongst these groups. Adolescents with biopsy-proven NAFLD and lean controls completed the Harvard Food Frequency Questionnaire. Twenty-eight NAFLD and 15 lean controls were studied. NAFLD with (n = 20) and without NASH (n = 8) had similar total calorie, protein, fat, and carbohydrate intake. Subjects with NASH had higher total sugar (122.3 ± 48.3 vs 83.1 ± 38.8 g), glucose (24.3 ± 9.3 vs 15.2 ± 7.5 g), sucrose (42.3 ± 16.9 vs 28.8 ± 11.7 g), and fructose (29.4 ± 12.5 vs 18.1 ± 8.0 g) intake than those with NAFLD but without NASH ( P < 0.05). Both NAFLD groups had similar micronutrient intake. Alanine aminotransferase (ALT) correlated with total caloric intake ( ρ = 0.4; P = 0.04). Total carbohydrate calories correlated with a higher NAS summary score ( ρ = 0.38; P = 0.04) and lobular inflammation ( ρ = 0.50; P = 0.007). Percent calories from added sugar and glucose correlated with worsening NAS summary score ( ρ = 0.44, P = 0.02; ρ = 0.48, P = 0.009) and lobular inflammation ( ρ = 0.51, P = 0.006; ρ = 0.53, P = 0.004). Percent calories from fructose correlated with lobular inflammation ( ρ = 0.56; P = 0.002). Total daily calories, protein, fat, carbohydrate, and micronutrient intake were similar between NAFLD and lean controls. NASH patients consume similar total calories, protein, and fat as those without NASH, but have significantly higher sugar intake. NAFLD and lean children, however, have similar macro/micronutrient intake. Histologic disease severity correlates with total carbohydrate and added sugar intake, supporting a role for simple sugar intake in NAFLD progression.

Status of dietary micronutrient intakes among the children of 12-17 years old in China from 2016 to 2017

To analyze the status of dietary micronutrient in takes among the children of 12-17 years old in China from 2016 to 2017. Multistage stratified random sampling method was used to collect data in 275 monitoring sites of the China National Nutrition and Health Survey of Chinese children and lactating mothers in 31 provinces of China from 2016 to 2017. Three consecutive 24-hour recalls method wasused to collect the information of food intake, and household or school canteen edible oil and condiments weighing were adopted. The dietary micronutrient were analyzed based on theChina Food Composition table. The average daily intakes of vitamin A(retinol activity equivalents), vitamin B_1(thiamine), vitamin B_2(riboflavin), vitamin C(ascorbic acid), calcium, iron, zinc and sodium were 356.8 μ g, 0.8 mg, 0.8 mg, 60.5 mg, 342.8 mg, 19.2 mg, 9.8 mg and 5 230.4 mg, respectively. The proportion ofdaily average intakes of vitamin A, vitamin B_1, vitamin B_2, vitamin C and calcium lower than 60% of the recommended value were 74.3%, 59.4%, 57.7%, 62.6% and 93.0%, respectively. The proportion of daily intake of iron and zinc reaching 80% of the recommended value were 73.8% and 64.8%, respectively. The proportion of daily average intake of sodium exceeded the appropriate intake by 94.4%. The average daily intakes of micronutrients increased with age among the children of 12-17 years old. There were differences of daily intake of vitamin A in gender, urban and rural areas(P&lt;0.05), there was difference of vitamin C in urban and rural areas(P&lt;0.01), there were differences of daily intake of vitamin B_1, vitamin B_2, calcium, iron and zinc in age, gender, urban and rural areas(P&lt;0.01), there were differences in the average daily intake of sodium in age, gender(P&lt;0.01). The average daily dietary of iron and zinc intakes in the diet were basically enough in most children of 12-17 years old in China, that of sodium was too much, and that of some micronutrients was insufficient.

Inadequate intake of vitamins and minerals among high-school pupils in the Moroccan Rif region

BACKGROUND: Inadequate nutrient intakes in adolescents may negatively affect their future health. The identification of inadequate micronutrient intakes by dietary study provides essential information to guide educational strategies for promoting healthy eating habits. OBJECTIVE: To assess the daily micronutrient intake and the prevalence of inadequacy in a sample of middle and high-school pupils in the Rif region of Morocco. METHODS: A cross-sectional study collected dietary information from food records over three non-consecutive days in a sample (n = 302) of Moroccan Riffian adolescents (12–18 years). The DIAL software, adapted for commonly eaten Moroccan foods, was used to estimate micronutrient intakes. The proportion of individuals with intakes below the Estimated Average Requirement (EAR) or the Adequate Intake (AI) level and the probability approach were used to estimate the prevalence of inadequacy. RESULTS: Regardless of gender and age group, our subjects were found to be particularly at risk of inadequate intakes of vitamins E and D, calcium and potassium. Older adolescents (14–18 years) also showed a risk of inadequate intake of folate, biotin, magnesium, iodine and zinc (among boys). CONCLUSION: For many nutrients, the daily diets of our Riffian adolescents do not meet the recommended intake levels. We emphasize the need for monitoring the dietary habits of adolescents and the development of nutrition education programs. Further studies which include the clinical and biological assessment of nutritional status, as well as the regular collection of quality and nationally representative micronutrient data, are recommended.

Importance of breakfast in teenagers

Breakfast is the main and important meal of the day. There are many side effects of skipping breakfast and also we can get a lot of benefits from having breakfast. It gives strength to the body, increases the strength of the body, and the ability to spend the whole day in a fresh mood. Some children avoid this and suffer from many ailments. Such as Gastritis,migraine , lack of concentration , low energy level. Breakfast can make it easier for students to achieve their daily micronutrient intake. Children who eat breakfast on a daily basis receive 50 percent more iron, vitamins. According to research published in the international Frontiers in Human Neuroscience. Breakfast eaters also get a huge amount of fibre and have decreased their body weight, cholesterol level than the skippers. Prior to starting the college day, college students who consume an exact breakfast have greater concentration, examination results, strength, nutrition and mineral intake, and even a healthy way of life weight. Breakfast is mainly crucial for young pupils, as the Genius consumes nearly 1/2 of the body's energy.

Dietary Micronutrient Status and Relation between Micronutrient Intakes and Overweight and Obesity among Non-Pregnant and Non-Lactating Women Aged 18 to 49 in China.

Women between the ages of 18 and 49 are women of reproductive age, for whom physical health and nutritional status are closely related to successful pregnancy, good pregnancy outcomes and the nurturing of the next generation. Overweight and obesity have become important nutrition and health problems of women aged 18–49 years in China. In social life, non-pregnant and non-lactating Chinese women aged 18–49 are the most vulnerable and neglected group. At present, there are no research data on their dietary micronutrient intake, and the relationship between dietary micronutrient intake and overweight and obesity in China. However, non-pregnant and non-lactating women aged 18–49 are the best window of opportunity to implement strategies, correct nutrition and improve physical health. It remains to be explored whether their overweight and obesity are related to inadequate dietary micronutrient intake. The aim of this study was to evaluate dietary micronutrient intake in non-pregnant and non-lactating Chinese women aged 18–49 years, and to analyze the relationship between dietary micronutrient intake and overweight and obesity. Data were obtained from 2015 China Adult Chronic Disease and Nutrition Surveillance (CACDNS 2015). In CACDNS 2015, 12,872 women aged 18 to 49 years (excluding pregnant women and lactating mothers) were surveyed for a three-day 24 h dietary recall and a three-day household weighing of edible oil and condiments. The average daily dietary intake of micronutrients was calculated according to the Chinese food composition table. In 2015, the median intake of vitamin A, vitamin B1, vitamin B2, vitamin C and folate in non-pregnant and non-lactating women aged 18–49 years in China was 267.0 μg RE/day, 0.7 mg/day, 0.6 mg/day, 63.5 mg/day and 121.0 μg/day, respectively. The median mean intake of vitamin A, niacin, calcium and zinc in overweight/obese group was lower than that in non-overweight/obese group, and the difference was statistically significant (p < 0.05). Multivariate Logistic regression analysis showed that vitamin A intake (Q3 vs. Q1: OR = 0.785, 95% CI: 0.702~0.878; Q4 vs. Q1: OR = 0.766, 95% CI: 0.679~0.865), niacin intake (Q2 vs. Q1: OR = 0.801, 95% CI: 0.715–0.898; Q3 vs. Q1: OR = 0.632, 95% CI: 0.554~0.721; Q4 vs. Q1: OR = 0.662, 95% CI: 0.568~0.772), Zinc intake (Q4 vs. Q1: OR = 0.786, 95% CI: 0.662~0.932) were a protective factor for overweight/obesity in women, while vitamin B2 intake (Q2 vs. Q1: OR = 1.256, 95% CI: 1.120~1.408; Q3 vs. Q1: OR = 1.416, 95% CI: 1.240~1.617; Q4 vs. Q1: OR = 1.515, 95% CI: 1.293–1.776), vitamin E intake (Q2 vs. Q1: OR = 1.114, 95% CI: 1.006–0.235; Q3 vs. Q1: OR = 1.162, 95% CI: 1.048~0.288; Q4 vs. Q1: OR = 1.234, 95% CI: 1.112–1.371) was a risk factor for overweight/obesity in females. The intakes of most dietary micronutrients in non-pregnant and non-lactating women aged 18–49 in China were low. The intakes of dietary vitamin A, niacin and zinc were negatively correlated with the risk of overweight/obesity, while the intakes of vitamin B2 and vitamin E were positively correlated with the risk of overweight/obesity.

Intake and adherence to energy and nutrient recommendations among women and men with binge-type eating disorders and healthy controls.

Research quantifying dietary intake in individuals with bulimia nervosa and binge-eating disorder (i.e., binge-type eating disorders) is surprisingly scant. We assessed the dietary intake of women and men with binge-type eating disorders in a large case-control study and compared them with healthy controls. We also evaluated the extent to which their dietary intake adhered to the Nordic Nutrition Recommendations. Among cases, we assessed the relationship of binge eating frequency with energy and macronutrient intake. We derived the total daily energy, macro-, and micronutrient intake of 430 cases with binge-type eating disorders (women: n=391, men: n=39) and 1227 frequency-matched controls (women: n=1,213, men: n=14) who completed the MiniMeal-Q, a validated food frequency questionnaire. We calculated mean intake for men and women and, in women, compared mean intake of energy and nutrients between cases and controls using linear regression. We calculated the proportion of women and men who met the recommended intake levels from the NNR, and compared these proportions in female cases and controls using logistic regression. We used linear regression to examine energy and macronutrient intake of women with varying frequencies of current binge-eating. Female, but not male cases, had a higher mean intake of total energy/day compared with controls and higher intake than recommended. The majority in all groups (male and female cases and controls) exceeded saturated fat recommendations, and did not meet recommendations for omega-3 fatty acid intake. Among all groups, adherence was low for vitamin D, selenium, and salt. Iron and folate intake was low among the majority of women, especially controls. Female cases with ≥4 binge-eating episodes in the past 28 days had higher intake of energy and percent carbohydrates, and lower intake of percent fat, compared to cases with no binge-eating episodes in the past month. Higher than recommended total daily energy intake among women with binge-type eating disorders may lead to weight gain and downstream health complications, if persistent. In most women, iron and folate intake was insufficient, which may have negative consequences for reproductive health. We found suboptimal adherence for key nutrients that are important to limit (saturated fat and salt) or meet (omega-3 fatty acids) for cardiovascular and overall health in all groups. Nutrition counseling should form an important pillar of treatment to assist with normalization of eating patterns and may also benefit individuals without eating disorders to optimize nutrient intake for long term health promotion.
