Feeding immunity: skepticism, delicacies and delights.

Immunologists studying the relationship between nutrition and immunological function face many challenges. We discuss here some of the historical skepticism with which nutritional research has often been faced and the complexities that need to be overcome in order to provide meaningful mechanistic insights.

National school food standards in England: a cross-sectional study to explore compliance in secondary schools and impact on pupil nutritional intake.

BACKGROUND: Many countries have introduced school food standards to improve the dietary intakes of school-aged children. England has school food standards (SFS) legislation in place but little is known about how well secondary schools comply with this. We aimed to assess compliance with the SFS legislation in English secondary schools and explore the impact of the SFS on pupils' nutritional intake. METHODS: We conducted a cross-sectional study with English secondary schools from 2019 to 2022. We compared SFS compliance and pupil nutritional intake in schools mandated or not mandated to comply with the SFS legislation, and explored the association between school compliance and pupil nutritional intake. We assessed the percentage of SFS (%SFS) complied with by reviewing school food menus and observing food served in school canteens. We assessed pupil nutritional intake using a 24-hour dietary recall measure (Intake24) and estimated intakes of free sugar (primary outcome) and other nutrients/foods. We used adjusted multilevel models to compare pupil intakes in the SFS-mandated and SFS-non-mandated schools, and to explore the association between school SFS compliance and pupil intakes. RESULTS: 36 schools (23 not mandated and 13 mandated to comply with the SFS) and 2,273 pupils participated. The median %SFS complied with was 63.9% (interquartile range 60.0-70.0%). This was similar for SFS-non-mandated (64.5%) and SFS-mandated schools (63.3%). Compliance was highest for standards applying to lunchtime (median = 81.3%) and lowest for those applying across the whole school day (median = 41.7%). It was also lower for standards restricting high fat, sugar and energy-dense items (median = 26.1%) than for standards aiming to increase dietary variety (median = 92.3%). Pupils from SFS-mandated schools had a lower mean lunchtime intake of free sugar (g) (adjusted mean difference: -2.78g; 95% CI: -4.66g to -0.90g). There were few significant associations between %SFS complied with and pupil nutritional intake. CONCLUSIONS: English secondary schools do not fully comply with SFS legislation regardless of whether they are mandated to comply. Schools and caterers may require monitoring and support to fully comply. There is little evidence that SFS compliance is associated with better pupil nutritional intake. Food environments outside of school also need to be considered. STUDY REGISTRATION: ISRCTN68757496 (17-10-2019).

Myanmar immigrant women's perceptions, beliefs, and information-seeking behaviors with nutrition and food practices during pregnancy in Thailand: a qualitative study.

BACKGROUND: Although nutrition is an essential contributor to the quality of pregnancy outcomes, little is known about the experiences and influences affecting dietary behaviors during pregnancy among migrant women, particularly those from Myanmar, the largest immigrant population in Thailand. To fill this gap, we conducted a descriptive qualitative study to explore Myanmar immigrant women's perceptions, beliefs, and information-seeking behaviors concerning nutrition and food practices during pregnancy. METHODS: We conducted focus group discussions (FGDs) with fifty Myanmar immigrant pregnant women aged 18-45 years across all trimesters, who were recruited using purposive sampling from a public tertiary hospital. The FGDs were conducted in Thai or Myanmar using semi-structured guides that probed women's pregnancy perceptions and experiences about nutrition and food patterns during pregnancy. The FGDs were audio-recorded, translated, and transcribed. Direct content analysis was used to guide the analysis through an ecological perspective framework. RESULTS: The seven FGDs with fifty women revealed four major themes involving perceptions, beliefs, and information-seeking behaviors. The qualitative results consisted of (1) a positive attitude toward better changes under difficult conditions (setting goals for infant health; uncertainty about changes); (2) beliefs about eating patterns and dietary practices during pregnancy (taboos aimed at protecting women's health and ensuring safe childbirth; taboos aimed at guaranteeing infant safety); (3) limited access to appropriate information about nutrition (unclear dietary information from healthcare providers; ease of learning from experiences in informal social networks); and (4) difficult living conditions in a non-native setting (work-related influences on dietary behaviors; lack of comprehensible language to gain food literacy). In addition, the results were highlighted across four levels of ecological perspectives. CONCLUSIONS: Immigrant pregnant women are a vulnerable population that should be treated with equity to ensure quality of life through optimal nutrition throughout pregnancy. Respectful care requires that healthcare providers develop culturally sensitive nutrition interventions to increase nutrition literacy, accessibility, and pregnancy outcomes.

Exploring tradeoffs among diet quality and environmental impacts in self-selected diets: a population-based study.

PURPOSE: Proposed sustainable diets often deviate dramatically from currently consumed diets, excluding or drastically reducing entire food groups. Moreover, their environmental sustainability tends to be measured only in terms of greenhouse gases emissions. The aim of this study was to overcome these limitations and identify a cluster of already adopted, relatively healthy diets with substantially lower environmental impacts than the average diet. We also aimed to estimate the reduction in multiple environmental impacts that could be achieved by shifting to this diet cluster and highlight possible tradeoffs among environmental impacts. METHODS: The diet clusters were identified by applying energy-adjusted multiple factor analysis and hierarchical clustering to the dietary data of the National FinHealth 2017 Study (n = 5125) harmonized with life cycle assessment data on food products from Agribalyse 3.0 and Agri-Footprint using nutrient intakes and global warming potential, land use, and eutrophication of marine and freshwater systems as the active variables. RESULTS: We identified five diet clusters, none of which had the highest overall diet quality and lowest impact for all four environmental indicators. One cluster, including twenty percent of the individuals in the sample was identified as a "best compromise" diet with the highest diet quality and the second lowest environmental impacts of all clusters, except for freshwater eutrophication. The cluster did not exclude any food groups, but included more fruits, vegetables, and fish and less of all other animal-source foods than average. Shifting to this cluster diet could raise diet quality while achieving significant reductions in most but not all environmental impacts. CONCLUSION: There are tradeoffs among the environmental impacts of diets. Thus, future dietary analyses should consider multiple sustainability indicators simultaneously. Cluster analysis is a useful tool to help design tailored, socio-culturally acceptable dietary transition paths towards high diet quality and lower environmental impact.

Maternal diet quality trajectories from pregnancy to 3.5 years postpartum and associated maternal factors.

PURPOSE: This study examined maternal diet quality trajectories from pregnancy to 3.5 years postpartum and associated maternal factors. METHODS: Data of 473 Australian women from the Healthy Beginnings Trial were used. A food frequency questionnaire collected dietary intake in pregnancy and 1, 2 and 3.5 years postpartum. Diet quality scores were calculated using the 2013 Dietary Guideline Index (DGI-2013) and RESIDential Environments Guideline Index (RDGI). Group-based trajectory modelling identified diet quality trajectories from pregnancy to 3.5 years postpartum. Multivariable logistic regression investigated factors associated with maternal diet quality trajectories. RESULTS: Two stable trajectories of low or high diet quality were identified for the DGI-2013 and RDGI. Women who smoked had higher odds of following the low versus the high DGI-2013 (OR 1.77; 95%CI 1.15, 2.75) and RDGI (OR 1.80; 95%CI 1.17, 2.78) trajectories, respectively. Women who attended university had lower odds of following the low versus the high DGI-2013 (OR 0.41; 95%CI 0.22, 0.76) and RDGI (OR 0.38; 95%CI 0.21, 0.70) trajectories, respectively. Women who were married had lower odds of following the low versus the high DGI-2013 trajectory (OR 0.39; 95%CI 0.17, 0.89), and women who were unemployed had higher odds of following the low versus the high RDGI trajectory (OR 1.78; 95%CI 1.13, 2.78). Maternal age, country of birth, household composition and pre-pregnancy body mass index were not associated with diet quality trajectories. CONCLUSION: Maternal diet quality trajectories remained stable from pregnancy to 3.5 years postpartum. Women who smoked, completed high school or less, were not married or were unemployed tended to follow low, stable diet quality trajectories.

The association between diet quality and chrononutritional patterns in young adults.

PURPOSE: Young adults eat erratically and later in the day which may impact weight and cardiometabolic health. This cross-sectional study examined relationships between chrononutritional patterns and diet quality in two young adult populations: a university and community sample. METHODS: Three days of dietary data were collected including food images captured using wearable cameras. Chrononutritional variables were extracted: time of first and last eating occasions, caloric midpoint (time at which 50% of daily energy was consumed), number of eating occasions per day, eating window, day-to-day variability of the above metrics, and evening eating (≥20:00h). The Healthy Eating Index for Australian Adults scored diet quality. Statistical analyses controlled for gender, body mass index, and socio-economic status. RESULTS: No significant associations between chrononutritional patterns and diet quality were found for all participants (n = 95). However, differences in diet quality were found between university (n = 54) and community (n = 41) samples with average diet quality scores of 59.1 (SD 9.7) and 47.3 (SD 14.4), respectively. Of those who extended eating ≥20:00 h, university participants had better diet quality (62.9±SE 2.5 vs. 44.3±SE 2.3, p < 0.001) and discretionary scores (7.9±SE 0.9 vs. 1.6±SE 0.6, p < 0.001) than community participants. University participants consumed predominately healthful dinners and fruit ≥20:00h whereas community participants consumed predominately discretionary foods. CONCLUSION: For the general young adult population, meal timing needs to be considered. Food choices made by this cohort may be poorer during evenings when the desire for energy-dense nutrient-poor foods is stronger. However, meal timing may be less relevant for young adults who already engage in healthy dietary patterns.

Higher global diet quality score is inversely associated with odds of metabolic syndrome among Iranian adults.

BACKGROUND: Growing research underscores the significance of diet quality in the development of Metabolic Syndrome (MetS). Our study investigates the correlation between the Global Diet Quality Score (GDQS) and MetS, along with its components, in Iranian adults. METHODS: This study utilizes data from the Yazd Health Study (YaHS) and includes a final analysis of 2,904 participants aged 20-70 years. Dietary data were gathered using food frequency questionnaires. MetS was defined in line with the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria. GDQS was derived by totaling the points across all 25 food groups, with scores ranging from 0 to 49. To examine the association between GDQS and MetS, multivariable logistic regression analyses were conducted in both crude and adjusted models. RESULTS: Participants who had the highest adherence to GDQS had a 20% lower chance of having MetS than those who had the lowest adherence after adjusting for confounding variables in Model II (T3 vs. T1: OR = 0.80; 95% CI: 0.46-0.99, P-trend = 0.045). There was no association between GDQS and MetS components including increased blood pressure, fasting blood glucose (FBG), triglyceride, abdominal obesity and reduced high-density lipoprotein (HDL) in crude and adjusted models. CONCLUSION: higher adherence to GDQS was inversely related to odds of MetS. Further longitudinal and clinical trials investigations are required to confirm these associations.

Evaluating the diet in Germany with two indices focusing on healthy eating and planetary healthy eating using nationwide cross-sectional food intake data from DEGS1 (2008-2011).

PURPOSE: To improve sustainability, adjustments to current diets are necessary. Therefore, limited planetary resources are considered within the healthy reference diet proposed by the EAT-Lancet Commission. The agreement with nationwide food intake was evaluated with two indices which reflect this reference and German food intake recommendations. METHODS: A healthy eating index (HEI-MON) reflecting the dietary guidelines of the German nutrition society and a planetary healthy eating index (PHEI-MON) reflecting the healthy reference diet were developed, with scores from 0 to 100. Both indices were applied to data from a nationally representative sample of the German population aged 18-79 years for which data from a 53-item food frequency questionnaire are available. RESULTS: Mean scores for the indices were 53 for HEI-MON and 39 for PHEI-MON. A better adherence to either guideline could be found among women, persons of older age as well as persons with higher education level. The sub-scores for HEI-MON showed high agreement with the recommendations for side dishes, fruit/nuts, (processed) meat and cereals, but low agreement with the recommendations for free sugar and vegetables/legumes. PHEI-MON sub-scores were highest for poultry, fruits and potatoes, and lowest for nuts, red meat and legumes. High scores in one index do not necessarily correspond to high scores in the other index. Individuals with more plantbased diets had higher scores in both indices, while high sugar and meat consumption led to lower scores. CONCLUSIONS: More plant-based diets are crucial for individual and planetary health. Both indices reflect such diets which consider already health and sustainability aspects. At an individual level, the scores for both indices may differ considerably, but overall there is a huge potential in the population to adapt to a diet more in line with both guidelines.

Early diet and the risk of coeliac disease. An update 2024 position paper by the ESPGHAN special interest group on coeliac disease.

This position paper by the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Special Interest Group on Coeliac Disease (SIG-CD) presents an update to the 2016 recommendations concerning early diet and the risk of coeliac disease (CD). This update adheres to the policy that mandates reviewing guidelines every 5 years, particularly when new data emerge. The 2024 statements and recommendations are essentially similar to the 2016 recommendations. Breastfeeding, whether any amount, exclusive, or of any duration, does not reduce the risk of developing CD. Introducing gluten into an infant's diet at any time between completed 4 months (≥17 weeks) and 12 months of age does not affect the cumulative incidence of CD, although earlier introduction may lead to earlier seroconversion and CD. In observational studies involving cohorts with a known risk for CD, consuming a high amount of gluten compared to a low amount during weaning and in the subsequent childhood years-specifically the first 2-3 years, and even up to 5 years in some studies-was associated with an increased risk for CD. However, the specific optimal amounts of gluten consumption remain undetermined due to insufficient evidence on safe thresholds, and the impact of restricting gluten in the diet of healthy children of unknown risk for CD is unknown. Thus, any recommendation on the gluten amount is currently unjustifiable for the general population and infants with known HLA risk types. There is no specific guidance on the type of gluten-containing foods to be introduced at weaning.

An unbiased, sustainable, evidence-informed Universal Food Guide: a timely template for national food guides.

BACKGROUND: Although national food guides are designed, ostensibly, to translate scientific evidence with respect to food, dietary patterns, and health, their development has increasingly become a corporate/political process as well as scientific one; often with corporate/political influences overriding science. Our aim was to construct an unbiased, sustainable, evidence-informed Universal Food Guide to serve as a template for countries to develop their unique guides, thereby, provide a valid resource for health professionals, health authorities, and the public. METHODS: To address our aim, we conducted an integrative review of multiple evidence-informed sources (e.g., established databases, evidence syntheses, scholarly treatises, and policy documents) related to four areas: 1. Food guides' utility and conflicts of interest; 2. The evidence-based healthiest diet; 3. Constituents of the Universal Food Guide template; and 4. Implications for population health; regulation/governance; environment/climate/planetary health; and ethics. RESULTS: The eating pattern that is healthiest for humans (i.e., most natural, and associated with maximal health across the life cycle; reduced non-communicable disease (NCD) risk; and minimal end-of-life illness) is whole food, low fat, plant-based, especially vegan, with the absence of ultra-processed food. Disparities in national food guide recommendations can be explained by factors other than science, specifically, corporate/political interests reflected in heavily government-subsidized, animal-sourced products; and trends toward dominance of daily consumption of processed/ultra-processed foods. Both trends have well-documented adverse consequences, i.e., NCDs and endangered environmental/planetary health. Commitment to an evidence-informed plant-based eating pattern, particularly vegan, will reduce risks/manifestations of NCDs; inform healthy food and nutrition policy regulation/governance; support sustainable environment/climate and planetary health; and is ethical with respect to 'best' evidence-based practice, and human and animal welfare. CONCLUSION: The Universal Food Guide that serves as a template for national food guides is both urgent and timely given the well-documented health-harming influences that corporate stakeholders/politicians and advisory committees with conflicts of interest, exert on national food guides. Such influence contributes to the largely-preventable NCDs and environmental issues. Policy makers, health professionals, and the public need unbiased, scientific evidence as informed by the Universal Food Guide, to inform their recommendations and choices.

A food-exchange model for achieving the recommended dietary intakes for saturated fat in Irish children: analysis from the cross-sectional National Children's Food Survey II.

OBJECTIVE: To identify the main foods determining SFA intakes and model the impact of food exchanges to improve compliance with dietary fat recommendations in Irish children. DESIGN: Estimated food and nutrient intakes were obtained from a cross-sectional study, the National Children's Food Survey II. Participants were categorised into low, medium and high SFA consumers, and the contribution of food categories to SFA intakes was compared. A food-exchange model was developed, whereby a selected range of high SFA foods was exchanged with lower SFA or unsaturated fat alternatives. SETTING: Participants were randomly selected from primary schools throughout the Republic of Ireland. PARTICIPANTS: A representative sample of 600 Irish children (5-12 years). RESULTS: The main determinants of low and high SFA consumers were milk, cheese and butter. These foods, including snack foods and meat and meat products, were considered exchangeable foods within the model. Compared with baseline data, modelled intakes for total fat, SFA, MUFA and trans-fat presented decreases of 3·2, 2·7, 1·6 and < 0·1 % of total energy (% TE), respectively. PUFA, n-6, n-3 and alpha-linolenic acid showed increases of 1·0, 0·8, 0·2 and 0·1 % TE, respectively. Compliance with total fat, MUFA and trans-fat recommendations remained adequate (100 %). Adherence to SFA and PUFA recommendations improved from 18 to 63 % and 80 to 100 %, respectively. CONCLUSION: The food-exchange model decreased SFA intakes and increased PUFA intakes, suggesting modest dietary changes to children's diets can effectively improve their overall dietary fat profile.

Does the Nutritional Intake and Diet Quality of Children With Chronic Kidney Disease Differ From Healthy Controls? A Comprehensive Evaluation.

OBJECTIVE: Children with chronic kidney disease (CKD) experience many obstacles to achieving optimal dietary intake. Dietary intake patterns remain unexplored or poorly described. This study compares nutritional intake and diet quality of Australian children with CKD to controls. METHODS: A food frequency questionnaire captured intake data and was compared to controls. Nutritional intake was determined using individualized nutrient reference values, and diet quality described using the Australian Guide to Healthy Eating and the Australian Child and Adolescent Recommended Food Score. RESULTS: Children with CKD (n = 36) and controls (n = 82) were studied. Children with CKD had lower weight and height z scores, but higher body mass index (P < .0001 for all parameters). Children with CKD had adequate energy intake, and excessive protein and sodium intake (336% and 569%). They were significantly less likely to meet requirements for vitamin A (P < .001), thiamine (P = .006), folate (P = .01), vitamin C (P = .008), calcium (P < .0001), iron (P = .01), magnesium (P = .0009), and potassium (P = .002). No child met recommended vegetable intake; however, less than half of children with CKD met fruit (44%), grains (31%), and dairy serves (31%). They were also less likely to meet recommended fruit and dairy serves (P = .04 and P = .01, respectively). Non-core foods provided 36% of energy, and although comparable to controls, was contributed more by takeaway foods (P = .01). CONCLUSION: Children with CKD have reduced nutritional intake of key nutrients and consume more takeaways than controls. Attention to increasing core foods, limiting sodium intake, and managing restrictions while promoting nutrient density appears necessary.

Low Dietary Diversity and Low Haemoglobin Status in Ghanaian Female Boarding and Day Senior High School Students: A Cross-Sectional Study.

Background and Objectives: Anaemia is one of the most common forms of malnutrition globally, with most anaemia cases related to micronutrient deficiency. Diets with higher dietary diversity scores (DDS) are usually nutritionally diverse and could positively impact micronutrient status, including haemoglobin (Hb) concentration improvement. The study aimed to determine DDS and its association with the Hb concentration of Boarding and Day adolescent Senior High School students in Ghana. Materials and Methods: A semi-structured and three 24 h dietary recalls were used to obtain the participants' demographic and diet intake data, respectively. Hb concentration was assessed using a validated portable haemoglobinometer. DDS was evaluated using the Minimum Dietary Diversity for Women (MDD-W) approach. Results: A significant difference in the DDS between Boarding and Day students existed. Only 22% of the Boarding students had adequate dietary diversity, whereas 64% of the Day students had adequate dietary diversity. A significantly smaller proportion of the Boarding students consumed nuts and seeds, dairy, flesh foods, eggs, vitamin A-rich vegetables and fruits, other vegetables, and other fruits compared to Day students (p < 0.05, all). No significant difference (p = 0.925) in mean (±SD) Hb concentrations between Boarding (11.9 ± 1.1 g/dL) and Day (11.9 ± 1.1 g/dL) students was found. Additionally, no significant correlation between mean DDS and Hb concentration (p = 0.997) was recorded. Using Hb < 12 g/dL as the determination of anaemia, 55.1% Boarding and 57.8% Day students had anaemia. Conclusions: Low dietary diversity in Boarding students highlighted inadequate nutrition provided by school meals. Strategies to increase meal diversity should be prioritised by stakeholders in Ghana's educational sector.

Associations of food choice values and food literacy with overall diet quality: a nationwide cross-sectional study in Japanese adults.

To date, a limited number of studies have examined aspects of food choice values and food literacy in relation to some aspects of dietary behaviours. The aim of this cross-sectional study was to comprehensively examine the associations of food choice values and food literacy with diet quality. In total, 2231 Japanese adults aged 19-80 years completed questionnaires asking about food choice values (accessibility, convenience, health/weight control, tradition, sensory appeal, organic, comfort and safety) and food literacy characterised by nutrition knowledge, cooking skills, food skills and eating behaviours (hunger, food responsiveness, emotional overeating, enjoyment of food, satiety responsiveness, emotional undereating, food fussiness and slowness in eating). As a measure of diet quality, the Healthy Eating Index-2015 (HEI-2015) was calculated using a brief-type diet history questionnaire (BDHQ) or a food combination questionnaire (FCQ). In males, after adjustment for potential confounding factors (including age, BMI and the ratio of reported energy intake to estimated energy requirement), the HEI-2015 derived from BDHQ and that derived from FCQ were associated significantly (P ≤ 0·02) and positively with the food choice values of organic and inversely with food fussiness. In females, the HEI-2015 showed positive associations with the food choice values of health/weight control, nutrition knowledge and cooking skills and an inverse association with food fussiness, irrespective of the dietary assessment questionnaire (P ≤ 0·03). In conclusion, this study suggests that several aspects of food choice values and food literacy were associated with diet quality, and the aspects related differed between males and females.

Female Athlete Representation and Dietary Control Methods Among Studies Assessing Chronic Carbohydrate Approaches to Support Training.

The aim of this audit was to assess the representation of female athletes, dietary control methods, and gold standard female methodology that underpins the current guidelines for chronic carbohydrate (CHO) intake strategies for athlete daily training diets. Using a standardized audit, 281 studies were identified that examined high versus moderate CHO, periodized CHO availability, and/or low CHO, high fat diets. There were 3,735 total participants across these studies with only ∼16% of participants being women. Few studies utilized a design that specifically considered females, with only 16 studies (∼6%) including a female-only cohort and six studies (∼2%) with a sex-based comparison in their statistical procedure, in comparison to the 217 studies (∼77%) including a male-only cohort. Most studies (∼72%) did not provide sufficient information to define the menstrual status of participants, and of the 18 studies that did, optimal methodology for control of ovarian hormones was only noted in one study. While ∼40% of male-only studies provided all food and beverages to participants, only ∼20% of studies with a female-specific design used this approach for dietary control. Most studies did not implement strategies to ensure compliance to dietary interventions and/or control energy intake during dietary interventions. The literature that has contributed to the current guidelines for daily CHO intake is lacking in research that is specific to, or adequately addresses, the female athlete. Redressing this imbalance is of high priority to ensure that the female athlete receives evidence-based recommendations that consider her specific needs.

Food consumption patterns and nutrient intakes of infants and young children amidst the nutrition transition: the case of Lebanon.

BACKGROUND: This is the first study on dietary intakes of infants and young children in the Eastern Mediterranean Region, a region that is currently witnessing the nutrition transition. It aims at characterizing food consumption patterns amongst 0-4 year old children in Lebanon, evaluating their macro- and micronutrient intakes and assessing adherence to dietary recommendations. METHODS: Based on a national cross-sectional survey in 2012 (n = 866), the study collected data on sociodemographic and anthropometric characteristics, and one 24-hour dietary recall was administered. Nutrient intakes were compared with reference values: Estimated Average Requirement (EAR), Adequate Intake (AI) and Acceptable Macronutrient Distribution Range (AMDR). RESULTS: Milk was the highest contributor to energy intake (EI) in infants (95.8 and 56.5% in 0-5.9 months and 6-11.9 months old infants, respectively), while its intake was lower among toddlers and preschoolers (35.4 and 15.1%, respectively). In contrast, intakes of sweets and sweetened beverages were the highest in preschoolers compared to younger children, contributing 18.5% EI in preschoolers. Compared to dietary guidelines, the lowest dietary adherence was found for vegetables (17.8-20.7%) and fruits (14.4-34.3%). Protein intake was within the recommendations for the vast majority of children. Although total fat intake was lower in toddlers and preschoolers compared to infants, more than 40% of toddlers and preschoolers exceeded the AMDR for fat and 87.3% of preschoolers exceeded the upper limit for saturated fat. Only 3.6% of toddlers and 11.5% of preschoolers exceeded the AI level for dietary fiber. Micronutrient intake assessment showed that mean intakes in infants exceeded the AI for all micronutrients, except for vitamin D and magnesium. In toddlers, vitamin D and calcium were below the EAR among 84.7, and 44.6%, respectively. In preschoolers, most of the children (91.9%) had inadequate intakes of vitamin D, and a third had inadequate intakes of folate, calcium and vitamin A. CONCLUSIONS: This study identified priority issues for nutrition intervention in infants and young children in Lebanon. Concerted multi-stakeholder efforts are needed to instill heathier food consumption and nutrient intake patterns early in life.

Diet quality among Indigenous and non-Indigenous children and youth in Canada in 2004 and 2015: a repeated cross-sectional design.

OBJECTIVE: The objectives were to describe changes in diet quality between off-reserve Indigenous and non-Indigenous children and youth from 2004 to 2015 and examine the association between food security and diet quality. DESIGN: We utilised a repeated cross-sectional design using both the 2004 and 2015 nutrition-focused Canadian Community Health Surveys, including 24-h dietary recall. Diet quality was estimated according to the Healthy Eating Index (HEI). SETTING: The surveys were conducted off-reserve in Canada's ten provinces. PARTICIPANTS: Our analysis included children and youth 2-17 years old (n 18 189). Indigenous and non-Indigenous participants were matched, and using a general linear model, we tested time period and (non-)Indigenous identifiers, including their interaction effect, as predictors of HEI. RESULTS: Both Indigenous and non-Indigenous children and youth had significantly higher HEI scores in 2015 as compared to 2004. There was not a significant (non-)Indigenous and time period interaction effect, indicating the improvements in diet quality in 2015 were similar between both Indigenous and non-Indigenous populations. Improvements in diet quality are largely attributed to reductions in percentage energy from 'other' foods, though a disparity between Indigenous and non-Indigenous children and youth persisted in 2015. Overall, food security was lower among the Indigenous population and positively, and independently, associated with diet quality overall, though this relationship differed between boys and girls. CONCLUSIONS: School policies may have contributed to similar improvements in diet quality among Indigenous and non-Indigenous populations. However, an in-depth sex and gender-based analysis of the relationship between food security and diet quality is required.

Non-communicable disease prevention in Kosovo: quantitative and qualitative assessment of uptake and barriers of an intervention for healthier lifestyles in primary healthcare.

BACKGROUND: Smoking, physical inactivity, low fruit and vegetable consumption, and obesity are common in Kosovo. Their prevention is a priority to relieve the health system of from costly non-communicable disease treatments. The Accessible Quality Healthcare project is implementing a primary healthcare intervention that entails nurse-guided motivational counselling to facilitate change in the domains of smoking, diet, alcohol consumption and physical inactivity for at-risk patients. This study quantitatively assesses the uptake of motivational counselling and the distribution of health behaviours and stages of health behaviour change of the participants according to the intervention, as well as qualitatively describes experiences and perceived benefits of motivational counselling. METHODS: Study participants (n = 907) were recruited consecutively in 2019 from patients visiting the Main Family Medical Centres in 12 municipalities participating in the Kosovo Non-Communicable Disease Cohort study as part of the Accessible Quality Healthcare project. For the quantitative study, we used baseline and first follow-up data on smoking status, physical inactivity, obesity, fruit and vegetable as well as alcohol consumption, uptake of counselling, and stages for behavioural change. For the qualitative study, in-depth interviews were conducted with a subset of 26 cohort participants who had undergone motivational counselling. RESULTS: Motivational counselling was obtained by only 22% of the eligible participants in the intervention municipalities. Unhealthy behaviours are high even in persons who underwent counselling (of whom 13% are smokers; 86% physically inactive; 93% with inadequate fruit and vegetable consumption; and 61% are obese); only the rate of smoking was lower in those who obtained counselling. Among smokers, over 80% were still in the pre-contemplation phase of behaviour change. More advanced stages of behaviour change were observed among the highly prevalent group of inactive persons and participants with poor dietary habits, among the 5 intervention municipalities. According to the qualitative study results, the participants who obtained motivational counselling were very satisfied with the services but requested additional services such as group physical activity sessions and specialized services for smoking cessation. CONCLUSIONS: More tailored and additional primary health care approaches in accordance with patients' views need to be considered for the motivational counselling intervention to reach patients and efficiently facilitate lifestyle behaviour change.

Relationship between diet quality scores and the risk of frailty and mortality in adults across a wide age spectrum.

BACKGROUND: Beyond intakes of total energy and individual nutrient, eating patterns may influence health, and thereby the risk of adverse outcomes. How different diet measures relate to frailty-a general measure of increased vulnerability to unfavorable health outcomes-and mortality risk, and how this might vary across the life course, is not known. We investigated the associations of five dietary indices (Nutrition Index (NI), the energy-density Dietary Inflammatory Index (E-DII™), Healthy Eating Index-2015 (HEI-2015), Mediterranean Diet Score (MDS), and Dietary Approaches to Stop Hypertension (DASH)) with frailty and mortality. METHODS: We included 15,249 participants aged ≥ 20 years from the 2007-2012 cohorts of the National Health and Nutrition Examination Survey (NHANES). The NI combined 31 nutrition-related deficits. The E-DII is a literature-derived dietary index associated with inflammation. The HEI-2015 assesses adherence to the Dietary Guidelines of Americans. The MDS represents adherence to the traditional Mediterranean diet. DASH combines macronutrients and micronutrients to prevent hypertension. Frailty was evaluated using a 36-item frailty index. Mortality status was ascertained up to December 31, 2015. RESULTS: Participants' mean age was 47.2 ± 16.7 years and 51.7% were women. After adjusting for age, sex, race, educational level, marital and employment status, smoking, BMI, and study cohort, higher NI and E-DII scores and lower HEI-2015, MDS, and DASH scores were individually significantly associated with frailty. All dietary scores were significantly associated with 8-year mortality risk after adjusting for basic covariates and frailty: NI (hazard ratio per 0.1 point, 1.15, 95%CI 1.10-1.21), E-DII (per 1 point, 1.05, 1.01-1.08), HEI-2015 (per 10 points, 0.93, 0.89-0.97), MDS (per 1 point, 0.94, 0.90-0.97), and DASH (per 1 point, 0.96, 0.93-0.99). The associations of E-DII, HEI-2015, and MDS scores with 8-year mortality risk persisted after additionally adjusting for NI. CONCLUSIONS: NI, E-DII, HEI-2015, MDS, and DASH scores are associated with frailty and 8-year mortality risk in adults across all ages. Nevertheless, their mechanisms and sensitivity to predict health outcomes may differ. Nutrition scores have the potential to include measures of both consumption and laboratory and physical measures of exposure.

Variation in diet quality across sexual orientation in a cohort of U.S. women.

PURPOSE: Extensive prior research has shown that sexual minority women are more likely to have a number of cancer risk factors, thereby putting them at higher risk for cancer than heterosexual women. However, there has been little research evaluating the association between sexual orientation and diet quality. METHOD: Data come from participants (aged 24-54 years) enrolled in Nurses' Health Study 3, an ongoing, U.S.-based cohort study (N = 15,941). We measured diet using recommendations from the Dietary Approach to Stop Hypertension (DASH) and American Health Association (AHA) 2020 Strategic Impact Goals. RESULTS: We found limited evidence of differences across diet quality by sexual orientation. When examining predicted DASH scores, mostly heterosexual [predicted mean score (95% confidence interval), 24.0 (23.8, 24.3)] and lesbian [24.3 (23.8, 24.9)] women had healthier predicted DASH scores than the reference group of completely heterosexual women with no same-sex partners [23.6 (23.5, 23.7)]. Even though certain sexual minority women had overall healthier predict DASH scores, their consumption of certain food groups-low-fat dairy and fruit-was lower than completely heterosexual women with no same-sex partners. When measuring AHA scores, most sexual minority groups (completely heterosexual women with same-sex partners, mostly heterosexual women, and lesbian women) had higher diet quality compared to the reference group of completely heterosexual women with no same-sex partners. CONCLUSION: Sexual minority women, particularly mostly heterosexual women and lesbian women, had healthier diet quality than completely heterosexual women with no same-sex partners. These data suggest that cancer risk factors (e.g., smoking, drinking, and inactivity) other than diet would drive higher cancer rates among sexual minority compared to heterosexual women. Nonetheless, it is critical for all women to improve their diet quality since diet quality was poor among participants of all sexual orientations.
