The 2020–2025 Dietary Guidelines for Americans recommend limiting intakes of saturated fat and added sugars (SF/AS) to <10% total energy. Data-driven approaches to identify sources of SF/AS are needed to meet these goals. We propose using a population-based approach to identify the leading food and beverage sources of SF/AS consumed by US adults. Foods and beverages reported as consumed were assessed from two, 24 h dietary recalls (24HRDR) from 36,378 adults aged 19 years and older from the 2005–2018 National Health and Nutrition Examination Survey. Intakes of SF/AS were aggregated across both 24HRDR to identify What We Eat in America food categories accounting for ≥90% of SF/AS, respectively, by the total population and within population subgroups. Data were weighted to estimate a nationally representative sample. Ninety-five discrete food categories accounted for ≥90% of the total SF/AS intakes for >88% of the representative sample of U.S. adults. The top sources of SF were cheese, pizza, ice cream, and eggs. The leading sources of AS were soft drinks, tea, fruit drinks, and cakes and pies. This analysis reflects a parsimonious approach to reliably identify foods and beverages that contribute to SF/AS intakes in U.S. adults. [ABSTRACT FROM AUTHOR]

Background: Non-communicable diseases are important causes of morbidity and mortality throughout the world. Methods: A community-based cross-sectional study conducted in 10 Indian states using multi-stage random sampling procedures. Information was collected on socio-economic and demographic particulars, anthropometric measurements such as height, weight and waist circumference, fasting blood glucose and blood pressure was measured. One day 24-h dietary recall was done for foods and nutrient intakes. Bivariate and multivariate step-wise logistic regression analyses was done. Results: The prevalence of overweight/obesity among rural adults was 23.4 % (95 % CI: 22.9–23.9), while age adjusted prevalence of pre-diabetes was 8.4 % (95 % CI: 8.1–8.7) and diabetes was 6.8, (95 % CI 6.7–7.1), respectively. The prevalence of diabetes was lowest in Uttar Pradesh, West Bengal and Odisha (3–4%) and higher in Kerala and Tamil Nadu (12–15 %). The odds of diabetes was 5.5 times more among elderly, 1.3 times higher among Christians and among high income groups, and 2 times among overweight (CI: 1.50–2.50), obese (CI: 1.61–2.76) and abdominal obesity (OR; 1.57; CI: 1.29–1.91) and 1.6 times more among hypertensives. The odds of diabetes were high among those consuming the lower tertiles of carbohydrates, pulses, milk and milk products and folic acid. Conclusion: the age-adjusted prevalence of diabetes and pre-diabetes was 6.8 % and 8.4 % respectively and the odds of diabetes was high among elderly, among high socio-economic groups, overweight/obese subjects and among hypertensives. Also, knowledge about symptoms of diabetes was low. There is a need to improve awareness for early diagnosis and treatment for control of diabetes and hypertension.

This study aimed to model how substituting foods consumed by Canadians for alternatives with more favourable nutrient profiling (NP) scores would impact dietary intakes. The Ofcom NP system, developed to help the UK Office of Communication differentiate foods that can be advertised to children, was applied to foods consumed by Canadians aged 2 years and older in the 2015 Canadian Community Health Survey (CCHS) (n = 19,447). Foods were substituted for similar options from the Euromonitor branded food composition database (Scenario 1) or from the primarily aggregated food profiles in the CCHS survey food composition database (Scenario 2) with either the most favourable (optimistic; 1A and 2A) or a more favourable Ofcom score (realistic; 1B and 2B). Mean intakes of Ofcom scores, calories, saturated fat, sugars, and sodium from these scenarios were compared to baseline. Only 2.9% of foods consumed had a similar Euromonitor option with a lower Ofcom score. Scenarios 1A, 1B, and 2A had lower Ofcom scores, calorie, sodium, saturated fat, and sugar intakes compared to baseline. Scenario 2B had lower levels of all outcome measures, except for an increase in calories compared to baseline. Selection of foods with more favourable NP scores has the potential to decrease the Canadian intake of nutrients of concern. [ABSTRACT FROM AUTHOR]

Background: Dietary guidelines are intended to inform and aid the general public, with the aim of improving healthy diets and reducing health risk. The effectiveness of these guidelines, however, is rarely investigated. Aim: This work investigates the effects of three different types of dietary recommendations for reducing free sugars, on free sugar intakes over 12 weeks. Secondary aims will also investigate how these different recommendations affect secondary outcomes, outcomes in subsets of the trial population, and identify barriers and facilitators to dietary change. Methods: Using a randomised controlled parallel-group trial with three intervention and one control arms, 240 individuals consuming >5% total energy intake from free sugars will be randomized to receive: nutrient-based, nutrient- and food-based, nutrient-, food- and food-substitution-based recommendations or no recommendations, with outcomes assessed for the following 12 weeks. Our primary outcomes are free sugar intakes and adherence to the recommendations. Secondary outcomes are daily energy intake, dietary composition, anthropometry, sweet food perceptions and preferences, sweet food choice, attitudes towards sweet foods, eating behaviour and food choice, knowledge and lifestyle variables, quality of life, adverse events, and barriers and facilitators towards intervention adherence. Results: Data will contribute to three distinct analyses: 1) Analyses to investigate the effects of the three different dietary recommendations versus control; 2) Analyses of the effects of the dietary recommendations in different population subgroups, and 3) Investigation of the barriers and facilitators to success. Conclusion: This work offers new perspectives on the effects of different dietary recommendations to enact behaviour change. [ABSTRACT FROM AUTHOR]

The D-enantiomers of L-amino acids are non-proteinogenic but widely present in foods. This is due to spontaneous racemization or processing, such as heating or alkali treatment, leading to substantial dietary exposure. Additional exposure to D-amino acids (D-AAs) comes from the human microbiota; D-AAs are present in bacterial surface proteoglycans, essential for bacterial competition and growth. Humans and other mammals have a complex set of genes for D-AA transport and degradation, and capacity to synthesize several D-AAs. Free D-AAs are present at low levels in human tissues and body fluids, yet they are apparently of considerable physiological and pathological importance. Amino acid transport regulates their presence and favors specific D-AAs, e.g. D-serine, D-aspartate, D-cysteine, and D-glutamate, over many others. Some of these D-AAs interact with the ubiquitous glutamate-gated Ca2+ channels, affecting signaling functions in most organs, especially the intestine, kidney, and brain. Consequently, the exposures, synthesis, local and systemic transport of D-AAs could be much more biologically important in humans than previously assumed, likely playing a role in gut-organ signaling and in many degenerative diseases.

Abstract Background/Objectives Celiac disease (CD) is a systemic and autoimmune enteropathy of the gastrointestinal tract with malabsorption characteristics. The only effective treatment for CD is adhere strictly to a gluten-free diet (GFD) throughout life. We evaluated the dietary patterns in celiac disease patients and their association with dietary intakes and anthropometric measurements in Iran. Subjects/Methods This is a case-control study on 182 participants who were referred to the Khuzestan Celiac Association, Iran. Nutritional information was collected using a validated 147-item semi-quantitative food frequency questionnaire (FFQ). The software Stata (StataCorp, Version 14.0) was used to analyze the data. Principal component analysis (PCA) was used to obtain participants’ dietary patterns. Results A significant relationship was observed between age and body mass index (BMI) across quartiles of the healthy dietary pattern score (P

Nutrition knowledge is an important factor that influences the nutritional status and health of the individual, group or community. Research studies have been trying to develop a reliable tool which can measure nutrition-related knowledge, nutrition-related awareness and its effect on dietary behaviour. Sports nutritionists usually base their dietary interventions on a nutrition education program with dietary guidelines. There are no. of cross-sectional studies for both coaches and athletes, reporting on nutrition knowledge. Achieving optimal physical condition and maximising athletic performance both depend heavily on nutrition. Our diet provides our bodies with the energy and nutrients they need to sustain physical activity, improve muscular function, and aid in recuperation. Any physical fitness program is incomplete without nutrition as it is an integral part of physical fitness. For any sportsman, the dietary goal is to obtain adequate nutrition to improve their health and fitness or performance in sports.4 A carefully organized nutrition program greatly improves athletic performance. Nutritional status is a crucial factor in determining the physical fitness and training of a sports individual. For sportsmen energy requirement or nutrient requirements are high due to their game. As it is known, appropriate nutrition improves the physical performance of the sportsmen. On the other hand, inadequate intake of nutrients leads to nutrient deficiencies therefore leading to poor performance and health problems. Many studies have provided strong evidence that optimal nutrition supports physical activity, recovery and athlete performance. However Apart from less nutritional knowledge, there are several factors such as restrictive dietary intake or excessive exercise which influence healthy eating. In addition, lack of knowledge, zeal to follow a nutritious diet, lack of money and lack of time, can be a potential reason not to follow a healthy diet. Athletes generally rely on their coaches for nutrition-related guidance. So, when coaches have less knowledge about nutrition it can be a potential problem for athletes to follow a healthy diet. In some Cross-sectional studies, it is found that Coaches Play a key role in providing nutritional-related information. However, they were not aware of the importance of nutrition on performance therefore not giving the necessary importance to their diets. Coaches have inadequate knowledge about sports nutrition and their role is critical as they are prime contact for the athletes to know about their diet to enhance their performance.

To examine the relationship between chewing performance and dietary intakes in children with Cerebral Palsy (CP). Forty children with CP aged between 2 and 6 years were included. The Karaduman Chewing Performance Scale (KCPS) and the Mastication Observation and Evaluation (T-MOE) instruments were used to evaluate chewing performance. Daily dietary intakes were measured from a 24-h food record with digital photographs including the amount and textures of all foods consumed during the meal. Chewing function was impaired in 70% of children. There was a negative low-to-moderate correlation between KCPS scores and daily protein intake (r = −0.32, p = 0.04), but not with energy and other macronutrients. The percentage of daily dietary intakes from 'liquid-blenderized' foods were positively correlated with KCPS, and negatively correlated with T-MOE scores (p < 0.001). There was a significant negative association between the percentage of daily dietary intakes from 'easy to chew & regular solid' foods and KCPS scores, and a significant positive association was found with T-MOE scores. In conclusion, the amount of daily protein intake decreased, and daily intake ratios of energy and macronutrients from liquid-blenderized foods increased as chewing performance decreased in children with CP. Timely diagnosis and treatment of chewing dysfunction can serve as a useful treatment option to ensure adequate dietary intake in children with CP, and also to decrease the burden of their parents and improve their quality of life.

Background/Objectives: Celiac disease (CD) is a systemic and autoimmune enteropathy of the gastrointestinal tract with malabsorption characteristics. The only effective treatment for CD is adhere strictly to a gluten-free diet (GFD) throughout life. We evaluated the dietary patterns in celiac disease patients and their association with dietary intakes and anthropometric measurements in Iran. Subjects/Methods: This is a case-control study on 182 participants who were referred to the Khuzestan Celiac Association, Iran. Nutritional information was collected using a validated 147-item semi-quantitative food frequency questionnaire (FFQ). The software Stata (StataCorp, Version 14.0) was used to analyze the data. Principal component analysis (PCA) was used to obtain participants' dietary patterns. Results: A significant relationship was observed between age and body mass index (BMI) across quartiles of the healthy dietary pattern score (P < 0.001, P = 0.001, and P = 0.001, respectively), indicating that as age and BMI increased, participants demonstrated greater adherence to the healthy dietary pattern. Individuals with the highest adherence to the healthy dietary pattern had the lowest odds ratio for celiac disease (CD) (Q1: reference; Q2: 1.96, 95% CI: 0.84–4.55; Q3: 0.61, 95% CI: 0.27–1.42; Q4: 0.10, 95% CI: 0.03–0.33, P trend < 0.001), and this association remained significant after adjusting for BMI (adjusted P trend = 0.003) and energy intake (adjusted P trend < 0.001). Moreover, there was a significant association between the lowest odds ratio for CD and the highest adherence to the unhealthy dietary pattern after adjustment for energy intake (Q1: reference; Q2: 0.38, 95% CI: 0.13–1.12; Q3: 0.21, 95% CI: 0.06–0.71; Q4: 0.07, 95% CI: 0.02–0.29, adjusted P trend < 0.001). Additionally, a significant association was observed between the odds ratio for CD and the mixed dietary pattern score (Q1: reference; Q2: 6.01, 95% CI: 2.29–15.72; Q3: 2.47, 95% CI: 0.93–6.55; Q4: 4.84, 95% CI: 1.84–12.66, P trend = 0.02), and this association remained significant after adjustment for energy intake (adjusted P trend < 0.001). Conclusions: The findings of the present study indicate that individuals who adhere to healthy dietary patterns have a lower incidence of celiac disease. [ABSTRACT FROM AUTHOR]

The objective of this study was to assess the feasibility and effectiveness of a novel WeChat applet-based personalized dietary intervention aimed at promoting healthier dietary intakes. A two-arm parallel, randomized, controlled trial was conducted in a real-world scenario and involved a total of 153 participants (the intervention group, n = 76; the control group, n = 77), lasting for 4 months in Shanghai, China. The intervention group had access to visualized nutrition evaluations through the applet during workday lunch time, while the control group received no interventions. A total of 3413 lunch dietary intake records were captured through the applet. Linear mixed models were utilized to assess the intervention effects over time. At baseline, the participants' lunchtime dietary intakes were characterized by insufficient consumption of plant foods (86.9% of the participants) and excessive intake of animal foods (79.7% of the participants). Following the commencement of the intervention, the intervention group showed a significant decrease in the animal/plant food ratio (β = −0.03/week, p = 0.024) and the consumption of livestock and poultry meat (β = −1.80 g/week, p = 0.035), as well as a borderline significant increase in the consumption of vegetables and fruits (β = 3.22 g/week, p = 0.055) and plant foods (β = 3.26 g/week, p = 0.057) over time at lunch compared to the control group. The applet-based personalized dietary intervention was feasible and effective in improving dietary intakes and, consequently, possibly may manage body weight issues in real-world scenarios.

Objectives: To generate reference data for bone mineral content (BMC) and bone mineral density (BMD) measures among apparently healthy children aged 4–5 y and to study the relationship of BMC and BMD with age, sex, anthropometric measures, dietary intakes, and serum vitamin D levels. Methods: This cross-sectional study was conducted among 219 urban preschool children, aged 4.0–5.11 y. Bone health (BMC and BMD) was measured using dual energy X-ray absorptiometry (DEXA). Anthropometric parameters were measured using standard methodology. The 24-h dietary recall method was used to assess the dietary intake of the children. Serum vitamin D levels were assessed using the ELISA kit method. Percentiles for BMC and BMD for each age and sex were constructed using the lambda-mu-sigma (LMS) method. Results: The mean BMD and BMC among children was 0.75 ± 0.04 g/cm2 and 544.9 ± 87.6 g, respectively, and were significantly different by age and sex category. The BMC and BMD values of boys and girls increased with age, with boys having significantly higher values. A significant positive correlation was observed for BMC and BMD with anthropometric measures and dietary intake of calcium, phosphorous, protein, zinc, and B vitamins. Conclusion: This study developed smoothed percentile curves for BMC and BMD in preschool children, which could be used as reference values for children from India. [ABSTRACT FROM AUTHOR]

Frailty is increasingly prevalent worldwide because of aging populations. Diet may play a role as a modifiable risk factor. This study aimed to investigate associations between dietary factors and risk of frailty in the UK Women's Cohort admitted to hospitals in England. Consumption of foods and nutrients was estimated using a validated 217-item food frequency questionnaire at baseline. Incident frailty was assessed via a hospital frailty risk score based on linkage with hospital episode statistics. Out of 25,186 participants admitted to hospitals, 6919 (27%) were identified with frailty and 10,562 (42%) with pre-frailty over a mean follow-up of 12.7 years. After adjustment for confounding, we observed a 12% increase in risk of frailty with each additional 10 g/MJ intake of total meat (HR = 1.12, 95%CI: 1.07, 1.17), with the highest risk observed for processed meats (HR = 1.45, 95%CI: 1.21, 1.73). Similar associations were observed with pre-frailty. Vegetable intake was associated with slightly lower risk of frailty (HR = 0.98, 95%CI: 0.97, 1.00). There was no evidence of association between most nutrient intakes and in-hospital frailty risk. Overall, our findings suggest that reducing consumption of meat, especially processed meat, in adults may be beneficial regarding the development of frailty. [ABSTRACT FROM AUTHOR]

The 2020–2025 Dietary Guidelines for Americans recommend limiting intakes of saturated fat and added sugars (SF/AS) to 88% of the representative sample of U.S. adults. The top sources of SF were cheese, pizza, ice cream, and eggs. The leading sources of AS were soft drinks, tea, fruit drinks, and cakes and pies. This analysis reflects a parsimonious approach to reliably identify foods and beverages that contribute to SF/AS intakes in U.S. adults.

Selection of foods with more favourable NP scores has the potential to decrease the Canadian intake of nutrients of concern.

Abstract Objective: The Global Dietary Database (GDD) expanded its previous methods to harmonise and publicly disseminate individual-level dietary data from nutrition surveys worldwide. Design: Analysis of cross-sectional data. Setting: Global. Participants: General population. Methods: Comprehensive methods to streamline the harmonisation of primary, individual-level 24-h recall and food record data worldwide were developed. To standardise the varying food descriptions, FoodEx2 was used, a highly detailed food classification and description system developed and adapted for international use by European Food Safety Authority (EFSA). Standardised processes were developed to: identify eligible surveys; contact data owners; screen surveys for inclusion; harmonise data structure, variable definition and unit and food characterisation; perform data checks and publicly disseminate the harmonised datasets. The GDD joined forces with FAO and EFSA, given the shared goal of harmonising individual-level dietary data worldwide. Results: Of 1500 dietary surveys identified, 600 met the eligibility criteria, and 156 were prioritised and contacted; fifty-five surveys were included for harmonisation and, ultimately, fifty two were harmonised. The included surveys were primarily nationally representative (59 %); included high- (39 %), upper-middle (21 %), lower-middle (27 %) and low- (13 %) income countries; usually collected multiple recalls/ records (64 %) and largely captured both sexes, all ages and both rural and urban areas. Surveys from low- and lower-middle v. high- and upper-middle income countries reported fewer nutrients (median 17 v. 30) and rarely included nutrients relevant to diet-related chronic diseases, such as n-3 fatty acids and Na. Conclusions: Diverse 24-h recalls/records can be harmonised to provide highly granular, standardised data, supporting nutrition programming, research and capacity development worldwide.

Background: Chronic respiratory diseases (CRDs) pose a significant global health burden. Antioxidant-rich diets have been associated with improved lung health, but the specific relationship with CRDs remains unclear. Methods: This study examined the relationship between dietary antioxidant intakes and CRDs using data from the 2001–2018 National Health and Nutrition Examination Survey (NHANES). Information on dietary antioxidant intakes, including vitamins A, C, and E, zinc, selenium, and carotenoid, were collected from the 2 24-h recall interviews to calculate composite dietary antioxidant index (CDAI). CRDs were determined based on self-reported physician diagnoses. To examine the relationship between CDAI and CRDs, multivariate logistic regression was used. To study potential non-linear correlations within these associations, restricted cubic spline (RCS) regression was performed. Results: The study involved 40 557 individuals. The median CDAI was −0.09 (−2.05, 2.25). We discovered those who were in the fourth quartile of CDAI scores had a 19% lower prevalence than those in the first quartile (OR = 0.81 [0.72–0.91], Ptrend < 0.01) after adjusting for all relevant covariates. The fourth quartile of CDAI was linked with a lower prevalence of emphysema (OR = 0.57 [0.40–0.81], Ptrend < 0.01) and chronic bronchitis (OR = 0.74 [0.62–0.88], Ptrend < 0.01). RCS regression showed that CDAI was non-linearly related to the prevalence of CRDs, with inflection points of 3.20 (P for non-linearity

Objective: There are some studies regarding the potential effects of temporomandibular disorders (TMD) on food intake and eating habits, however the comparison of nutritional intakes and status of individuals with and without TMD have not been adequately reported. Thus, the study aimed to assess the dietary intakes of individuals with TMD, and investigate if there is a difference in nutritional intakes between healthy individuals with and without TMD. Methods: Individuals were grouped as 'study group (with TMD)' versus 'control group (no TMD)' according to Fonseca Anamnestic Index. The Oral Health Impact Profile‐14 (OHIP‐14) was used to assess oral health‐related quality of life. Chewing function was evaluated with the Test of Masticating and Swallowing Solids (TOMASS). A 24‐h dietary recall method was used to measure daily dietary intakes of the participants, and daily energy, macro‐ and micronutrient intakes were calculated. In addition, all drinks and foods in dietary records were classified under a specific modification level as 'Liquid‐blenderized', 'Minced‐moist & soft' and 'Easy‐to chew & regular solid foods'. Results: The participants in the study group (30 participants) had higher OHIP‐14 score (p <.01) than control group (30 participants). According to TOMASS, number of bites (p =.003) and total time (p =.007) were both higher in the study group than control group. There was no difference in the number of chewing cycles (p =.100) and number of swallowing (p =.764) between groups. No difference was detected between groups in terms of energy, protein, carbohydrate and fat intake. There was no significant difference between groups in mean percentage of energy and macronutrient intakes from modified and regular food textures (p >.05). Conclusion: This study showed that there was no difference between individuals with and without TMD in terms of dietary intakes. The study results suggest that nutritional status of individuals with TMD is similar with healthy individuals without TMD. [ABSTRACT FROM AUTHOR]

Abstract Objective: To identify temporal patterns of sleep and eating among school-age children during school closure due to the COVID-19 pandemic and to examine their associations with lifestyle behaviours and dietary intake. Design: In this cross-sectional study, questionnaires were used to assess sleep and eating times, lifestyle behaviours and dietary intake during school closure. Latent class analysis was performed to identify temporal patterns of sleep and eating based on self-reported clock times for wake-up, going to bed and eating meals. Lifestyle behaviours and dietary intake were compared between latent classes. Setting: Forty-eight primary and secondary schools in Japan. Participants: Totally, 6220 children (aged 8–15 years). Results: Four patterns, labelled ‘Very early (20 % of children)’, ‘Early (24 %)’, ‘Late (30 %)’ and ‘Very late (26 %),’ were identified and ordered according to the circadian timing. Latter patterns were characterised by later timings of sleep and eating, especially in clock times for wake-up, breakfast and lunch compared with earlier patterns. Children with latter patterns had a less physically active lifestyle, longer screen time (≥4 h/d), shorter study time (

BackgroundFront-of-pack labeling (FOPL) has been identified as a cost-effective policy to promote healthy food environments and to help consumers make healthier food choices. Consumer surveys report that after implementation of mandatory ‘high in’ FOPL symbols between 30 and 70% of consumers choose or were willing to choose products with fewer ‘high in’ symbols. Health Canada has recently published FOPL regulations that will require prepackaged food and beverages that meet or exceed thresholds for sodium, total sugars, or saturated fat to display a ‘high in’ FOPL nutrition symbol.ObjectivesThe aims were to estimate the potential (1) dietary impact of substituting foods with similar foods that would display at least one less ‘high in’ symbol, and (2) the number of diet-related noncommunicable disease (NCD) deaths that could be averted or delayed due to estimated dietary changes.MethodsBaseline and counterfactual intakes of sodium, total sugars, saturated fats, and energy were estimated among Canadian adults (n = 11,992) using both available days of 24 h-recall data from the 2015 Canadian Community Health Survey-Nutrition (CCHS). Similar foods to those reported in CCHS that would display at least one less ‘high in’ symbol (n = 239) were identified using a Canadian branded food composition database. Based on current FOPL consumer research, identified foods were substituted for 30, 50, and 70% of randomly selected CCHS-Nutrition adult participants and for all adult participants. Potential health impacts were estimated using the Preventable Risk Integrated ModEl.ResultsMean dietary reductions of between 73 and 259 mg/day of sodium, 2.0 and 6.9 g/day of total sugars, 0.2 and 0.5 g/day of saturated fats, and 14 and 46 kcal/day of energy were estimated. Between 2,148 (95% UI 1,913–2,386) and 7,047 (95% UI 6,249–7,886) of deaths due to diet-related NCDs, primarily from cardiovascular diseases (70%), could potentially be averted or delayed if Canadians choose products with fewer ‘high in’ symbols.ConclusionResults suggest that FOPL could significantly reduce sodium and total sugar intakes among Canadian adults, the consequences of which could avert or delay an important number of diet-related NCD deaths. These findings provide relevant data to support the importance of the impending FOPL regulations.

Recommendations suggest limiting the intake of free sugar to under 10% or 5% of calories in order to reduce the risk of negative health outcomes. This study aimed to examine Canadian free sugar intake and model how intakes change following the implementation of a systematic reformulation of foods and beverages to be 20% lower in free sugar. Additionally, this study aimed to examine how calorie intake might be impacted by this reformulation scenario. Canadians' free sugar and calorie intakes were determined using free sugar and calorie data from the Food Label Information Program (FLIP) 2017, a Canadian branded food composition database, and applied to foods reported as being consumed in Canadian Community Health Survey—Nutrition (CCHS-Nutrition) 2015. A "counterfactual" scenario was modelled to examine changes in intake following the reformulation of foods to be 20% lower in free sugar. The overall mean free sugar intake was 12.1% of calories and was reduced to align with the intake recommendations at 10% of calories in the "counterfactual" scenario (p < 0.05). Calorie intake was reduced by 3.2% (60 calories) in the "counterfactual" scenario (p < 0.05). Although the overall average intake was aligned with the recommendations, many age/sex groups exceeded the recommended intake, even in the "counterfactual" scenario. The results demonstrate a need to reduce the intake of free sugar in Canada to align with dietary recommendations, potentially through reformulation. The results can be used to inform future program and policy decisions related to achieving the recommended intake levels of free sugar in Canada. [ABSTRACT FROM AUTHOR]

Abstract Lactating women of low‐ and middle‐income countries are prone to develop deficiencies in essential nutrients due to various demographic and socioeconomic components. This study aimed to estimate the adequacy of dietary intake and the determinants of diet quality of lactating women in rural Bangladesh. One‐day dietary recall (24‐Hour recall) data of 973 lactating women were obtained from the Bangladesh Integrated Household Survey (BIHS) 2018–2019. Nutrient adequacy was determined using the Estimated Average Requirement (EAR) cut‐point approach. The molar ratios of phytate to zinc, calcium, and iron were calculated. Mean Adequacy Ratio (MAR) was calculated to measure diet quality, and multiple linear regression analysis was performed to assess the sociodemographic determinants of MAR. While the intakes of protein and carbohydrate were equal to/above the Acceptable Macronutrient Distribution Range (AMDR) among most of the subjects, intakes of total energy and fat were below the reference intakes for 74.4% and 98.3%, respectively. Nutrient adequacy remained unmet for riboflavin, calcium, vitamin A, and folate among most (87.2%–97.6%) of the study population, and the mean (SD) MAR was 0.72 (0.12). Cereals were the major contributor of energy and B vitamins, while protein and iron mainly came from plant‐based sources. The molar ratio of phytate to iron was greater than the critical limit among most respondents. Maternal Body Mass Index (BMI) (beta = 0.003, p = .014) and education level (beta = 0.017, p = .038) were associated with their diet quality. The diet of most lactating women in rural Bangladesh indicates the inadequacy of several micronutrients. This can lead to a worsening of the double burden of malnutrition in women. Lactating women should be given special consideration when designing food and nutrition programs for reproductive women in rural Bangladesh.

Abstract Background There is increasing focus on moving populations towards healthier and more environmentally sustainable dietary patterns. The Australian Dietary Guidelines provide dietary patterns that promote health and wellbeing. It is unclear how these guidelines align with the more recently published global recommendations of the EAT-Lancet Planetary Health Reference Diet, and how Australian diets compare to both sets of recommendations. Methods Data from one 24-h recall collected for the 2011–13 National Nutrition and Physical Activity Survey were analysed for 5,920 adults aged 19–50 years. Subgroups of this population were identified by diet quality and lower or higher consumption of foods often considered to be environmentally intensive (higher animal meat and dairy foods) or associated with healthiness (higher vegetables and lower discretionary choices). Food group and nutrient composition of Australian diets were compared to diets modelled on the Australian Dietary Guidelines and Planetary Health Reference Diet. The environmental impacts of diets were estimated using an index of combined metrics. Results Compared with the Planetary Health Reference Diet, the Australian Dietary Guidelines contained more servings of the vegetable, dairy and alternatives, fruit, and discretionary choices. The amount of meat and alternatives was higher in the Planetary Health Reference Diet than Australian Dietary Guidelines due to the inclusion of more plant-based meat alternatives. The average Australian diet contained two to almost four times the Australian Dietary Guidelines and Planetary Health Reference Diet maximum recommended intake of discretionary choices, and provided inadequate amounts of the vegetables, cereals, unsaturated fats and meats and alternatives food groups, primarily due to lower intakes of plant-based alternatives. The average Australian diet also contained less dairy and alternatives than the Australian Dietary Guidelines. In the average Australian diet, red meat and poultry contributed 73% to the total servings of meat and alternatives compared to 33% and 10% for the Australian Dietary Guidelines and Planetary Health Reference Diet respectively. The modelled Australian Dietary Guidelines diet met the relevant nutrient reference value for all 22 nutrients examined, whereas the Planetary Health Reference Diet contained an inadequate amount of calcium. The environmental impact scores of the Planetary Health Reference Diet and Australian Dietary Guidelines were 31% and 46% lower than the average Australian diet. Conclusions Significant changes are required for Australians’ dietary intake to align more closely with national and global dietary recommendations for health and environmental sustainability.

Background: Hypertension is the leading cause of death throughout the world. The study was conducted to assess the prevalence, determinants and knowledge & practices about hypertension among rural adults in India. Methods: A community-based cross-sectional study was carried out in 10 major states of India. Information on socio-economic & demographic particulars was collected and anthropometric measurements like height, weight, waist & hip circumference and blood pressure were measured. Foods and nutrient intakes were assessed by 24-h recall method. Analysis was done using SPSS window 22. Results: The prevalence of pre-hypertension was 45.3% (95% CI: 44.6–46.0) and hypertension was 22% (95% CI: 21.5–22.3) (age standardized prevalence; 20.2%) while, overweight/obesity was 22.6% (95% CI: 22.2–23.0) as per Asian cut offs (BMI≥23). The prevalence of hypertension was higher in West Bengal (29.5%) and Kerala (28.9%) and low in Madhya Pradesh and Uttar Pradesh (16–19%). The odds of hypertension was 1.2 times higher among forward communities, businessmen, tobacco users and those consuming alcohol, 2–3 times higher among overweight (CI: 1.87–2.25) and obese (2.65–3.27). The odds of hypertension was 1.2 times higher among those consuming lower tertile of carbohydrates (CI = 1.02–1.41) and zinc (CI = 1.11–1.42). About 76% were aware of hypertension, 21% were old hypertensive & 19% were on treatment. Conclusions: Age standardized prevalence of hypertension was 20% among adults and was associated with age, occupation, overweight/obesity, tobacco and alcohol use, low intake of carbohydrates and zinc. Therefore, increasing awareness and consumption of healthy diet through behavior change communication will help to control hypertension among adults.

Aim:There is a need to understand autosomal dominant polycystic kidney disease (ADPKD) patients’ dietary habits since dietary interventions may have potential effects on ADPKD. In this study, we aimed to analyze the relationship between dietary nutrient intake and total kidney volume (TKV).Methods:This cross-sectional study was conducted on 54 ADPKD patients recruited from the Nephrology outpatient clinic between June and July 2014. TKV was determined by magnetic-resonance imaging and general characteristics, biochemical and urinary parameters were determined. The nutrient intakes of patients were calculated using the three-day dietary records obtained on three consecutive days.Results:The total kidney-volume median was found to be 1407 mL. Patients’ total dietary energy and protein intakes were 25.8±9.4 kcal/kg, 0.9±0.3 g/kg, respectively. The percentage of carbohydrates, protein, and fat in energy was 49±7%, 14±3%, 37±7%, respectively. The mean intakes of thiamin, riboflavin, B6, calcium, magnesium, and zinc were sufficient, the mean dietary potassium intake was insufficient; and sodium intake was excessive in both sexes. In females, there was a negative but weak correlation between dietary vitamin C intake and TKV. In males, a negative but weak correlation was found between TKV and dietary intake of fiber, water, vitamin B6, vitamin K, magnesium, and iron.Conclusions:Dietary micronutrient intake may affect TKV according to sex.

Objective: To identify temporal patterns of sleep and eating among school-age children during school closure due to the COVID-19 pandemic and to examine their associations with lifestyle behaviours and dietary intake. Design: In this cross-sectional study, questionnaires were used to assess sleep and eating times, lifestyle behaviours and dietary intake during school closure. Latent class analysis was performed to identify temporal patterns of sleep and eating based on self-reported clock times for wake-up, going to bed and eating meals. Lifestyle behaviours and dietary intake were compared between latent classes. Setting: Forty-eight primary and secondary schools in Japan. Participants: Totally, 6220 children (aged 8–15 years). Results: Four patterns, labelled 'Very early (20 % of children)', 'Early (24 %)', 'Late (30 %)' and 'Very late (26 %),' were identified and ordered according to the circadian timing. Latter patterns were characterised by later timings of sleep and eating, especially in clock times for wake-up, breakfast and lunch compared with earlier patterns. Children with latter patterns had a less physically active lifestyle, longer screen time (≥4 h/d), shorter study time (<2 h/d) and more frequent skipping of breakfast and lunch than those with earlier patterns. In addition, children with latter patterns had lower intakes of several vitamins, vegetables, fruits, fish and shellfish and dairy products and higher intakes of sugar and confectionaries and sweetened beverages. Conclusion: More than half of the participants had later wake-up, breakfast and lunch during school closure, which was associated with more unfavourable lifestyles and dietary intakes.

The importance of food components to potential benefits and risks to human health is gradually being consumer awareness. Milk is an important part of the lipid content of the human diet, and there are few detailed reports on the fatty acid (FA) profiles of retail milk. In the study, we developed a gas chromatography–mass spectrometry (GC-MS) method to simultaneously determine 82 FAs, including 11 even-chain saturated FAs, 10 odd-chain saturated FAs, 9 branched-chain saturated FAs, 30 monounsaturated FAs, and 22 polyunsaturated FAs; this was applied to analyze samples (186 samples) of commercially available milk from 22 provinces throughout China and to evaluate the nutritional value of these samples based on FA-related indices. The results showed that the overall composition of milk FAs among the different regions was numerically similar, and minor FAs showed few differences. When considering the retail milk FA composition and dairy fat intake in China, regional variations have a limited impact on FA consumption. Moreover, milk accounts for approximately one-third and

BackgroundFront-of-pack labeling (FOPL) has been identified as a cost-effective policy to promote healthy diets. Health Canada has recently published FOPL regulations that will require food and beverages that meet or exceed set thresholds for sodium, sugars, or saturated fat to display a ‘high in’ symbol on the front of the package. Although a promising measure, its potential impact on dietary intakes and health have not yet been estimated in Canada.ObjectiveThis study aims to estimate (1) the potential dietary impact of implementing a mandatory FOPL among Canadian adults; and (2) the number of diet-related non-communicable disease (NCD) deaths that could be averted or delayed due to these estimated dietary changes.MethodsBaseline and counterfactual usual intakes of sodium, total sugars, saturated fats, and calories were estimated among Canadian adults (n = 11,992) using both available days of 24 h recalls from the 2015 Canadian Community Health Survey-Nutrition. The National Cancer Institute method was used to estimate usual intakes, and adjusted for age, sex, misreporting status, weekend/weekday, and sequence of recall. Estimated counterfactual dietary intakes were modeled from reductions observed in experimental and observational studies that examined changes in sodium, sugars, saturated fat, and calorie content of food purchases in the presence of a ‘high in’ FOPL (four counterfactual scenarios). The Preventable Risk Integrated ModEl was used to estimate potential health impacts.ResultsEstimated mean dietary reductions were between 31 and 212 mg/day of sodium, 2.3 and 8.7 g/day of total sugars, 0.8 and 3.7 g/day of saturated fats, and 16 and 59 kcal/day of calories. Between 2,183 (95% UI 2,008–2,361) and 8,907 (95% UI 8,095–9,667) deaths due to diet-related NCDs, mostly from cardiovascular diseases (~70%), could potentially be averted or delayed by implementing a ‘high in’ FOPL in Canada. This estimation represents between 2.4 and 9.6% of the total number of diet-related NCD deaths in Canada.ConclusionResults suggest that implementing a FOPL could significantly reduce sodium, total sugar, and saturated fat intakes among Canadian adults and subsequently prevent or postpone a substantial number of diet-related NCD deaths in Canada. These results provide critical evidence to inform policy decisions related to implementing FOPL in Canada.

AimDietary intake as a modifiable factor has been reported to be associated with hearing loss (HL). The relationship between magnesium (Mg) and calcium (Ca) as common dietary nutrients and HL in the elderly has rarely been reported. This study aimed to assess the association between Mg and Ca intake and HL in older adults.MethodThis cross-sectional study included participants aged ≥70 years from the National Health and Nutrition Examination Survey (NHANES) 2005–2006, 2009–2010, and 2017–2018. Outcomes were low-frequency [pure-tone averages (PTAs) at 500, 1000, and 2000 Hz >25 dB] and speech-frequency (PTAs at 500, 1000, 2000, and 4,000 Hz >25 dB) HL. Multivariate logistic analysis was utilized to explore the association between dietary Mg and Ca intake and their combined intake (Ca/Mg, Ca*Mg) and HL, and was described as odds ratio (OR) and 95% confidence interval (CI).ResultsA total of 1,858 participants were included, of which 1,052 (55.95%) had low-frequency HL and 1,349 (72.62%) had speech-frequency HL. Dietary Ca intakes [OR = 0.86, 95%CI: (0.74–0.99)] and Mg intakes [OR = 0.81, 95%CI: (0.68–0.95)] and Ca * Mg [OR = 0.12, 95%CI: (0.02–0.87)] were associated with lower odds of low-frequency HL after adjusting for confounders. Similar, dietary Ca intakes [OR = 0.85, 95%CI: (0.77–0.95)] and Mg intakes [OR = 0.78, 95%CI: (0.68–0.90)] and Ca * Mg [OR = 0.23, 95%CI: (0.05–0.78)] were related to lower odds of speech-frequency HL. For different levels of Mg and Ca intake, the combined intake of Ca (≥1,044 mg) and Mg (≥330 mg) was related to lower odds of low-frequency HL [OR = 0.02, 95%CI: (0.00–0.27)] and speech-frequency HL [OR = 0.44, 95%CI: (0.21–0.89)].ConclusionDietary intakes of Mg and Ca were associated with lower odds of HL and are a promising intervention to be further explored in older adults with HL.

Cheese represents an important source of essential amino acids, vitamins, and trace elements such as copper (Cu), and zinc (Zn). Cheese can be contaminated with toxic heavy metals due to the use of contaminated ingredients, or during the manufacture process, and distribution. This study was taken to estimate the residual contents of some toxic metals including lead (Pb), cadmium (Cd), arsenic (As), and mercury (Hg), and trace elements such as zinc (Zn) and copper (Cu) in five of the most consumed cheese types in Egypt including Domiati, Feta, Karish, Mish, and Rumi. Moreover, calculation of the dietary intakes, and health risk assessment among children and adults were conducted. The obtained results revealed that Mish cheese had the highest residual content of Pb, and As. Karish cheese had the highest content of Cd, and Zn. Mercury was not detected in Feta and Domiati cheese. Calculation of the estimated daily intakes, hazard ratio, and hazard index revealed that consumption of cheese among Egyptian adults and children would not pose health risks. However, such data should be handled carefully as consumption of cheese will provide considerable concentrations of the total buildup of heavy metals to the Egyptian consumers. In addition, consumption of cheese will provide part of the human needs of the essential trace elements including Zn, and Cu. [ABSTRACT FROM AUTHOR]

The present study aimed to (1) examine the changes in sleep habits and dietary intake among school-aged children after the school re-opening from a 3-month closure (without school lunch) due to the COVID-19 pandemic, and (2) examine whether the changes differ between those with different temporal patterns of sleep and eating during school closure, namely, ‘Very early’, ‘Early’, ‘Late’ and ‘Very late’. The latter patterns were characterised by later timings of wake up, breakfast and lunch. Questionnaires were answered twice by 4084 children (aged 8–15 years), themselves and/or their parents: first in June 2020 (for assessing lifestyle during school closure) and second, from July 2020 to February 2021 (for assessing lifestyle after school opening). After school re-opening, the participants’ wake-up time became an hour earlier (95 % CI 1⋅0, 1⋅1) and sleep duration got 0⋅94 h shorter (95 % CI 0⋅91, 0⋅97) than during school closure. An increase in dietary intake was observed for thiamine, vitamin B6, potassium, fruits and dairy products, and a decrease was observed for sugars (as foods) and confectioneries and sweetened beverages, despite small effect sizes (Cohen’s d: 0⋅20–0⋅30). Significant changes in wake-up time, sleep duration and sweetened beverage intake were observed among children with the latter temporal patterns. Thus, children wake up earlier and sleep for shorter durations after school re-opening than during school closure; however, changes in dietary intake were generally insignificant. Dietary intake among school-aged children in Japan during school closure (without school lunch) might not be worse than that during school days with universal school lunch. [ABSTRACT FROM AUTHOR]

Proper nutritional management is important for the growth and development of children with motor or intellectual disabilities; however, few studies have investigated the nutrient intake of children with disabilities. This study aimed to investigate the nutrient intake and food groups that are the main sources of nutrients for children with disabilities. This cross-sectional observational study included twenty-five children (mean age, 11⋅8 years) from five hospitals in Japan. Using a 3-d weighed dietary record, we estimated the daily nutrient intake and food and beverage sources that contributed to nutrient intake. The mean values of calcium, magnesium, iron, vitamin A, thiamine, riboflavin, and vitamin C intake were below the recommended dietary allowance, and those of dietary fiber and potassium were below the levels recommended by the Tentative Dietary Goal for Preventing Lifestyle-related Diseases (DG). In contrast, the mean intake values of fat, saturated fatty acids, and sodium were above the DG levels. Dairy products, meat, vegetables, and cereals were found to be the major contributors of nutrients. Increased intake of vegetables may help alleviate insufficient micronutrient intake in children with disabilities. [ABSTRACT FROM AUTHOR]

Objective: To assess the dietary quality and determine the influence of food-away-from-home (FAFH) on dietary quality and weight status among faculty and staff. Participants and methods: Faculty and staff (n = 152) from a public university completed an online Food Frequency Questionnaire. Number of FAFH consumed per week, dietary intakes, dietary quality as assessed by the Healthy Eating Index (HEI)-2015, and body mass index (BMI) were measured. Results: On average participants consumed FAFH four times per week. FAFH was associated with increased intake of trans-fats (p < 0.05) and reduced HEI scores (p < 0.01). Increased consumption of trans-fats was associated with a high BMI (p < 0.001). Conversely, an increase in the HEI-2015 score was associated with a reduction in BMI (p < 0.05). Conclusion: Results suggest that the consumption of FAFH increased the intake of trans-fats and decreased diet quality, while improvements in diet quality, as measured by the HEI-score, were associated with reduced BMI among faculty and staff.

Lactating women of low‐ and middle‐income countries are prone to develop deficiencies in essential nutrients due to various demographic and socioeconomic components. This study aimed to estimate the adequacy of dietary intake and the determinants of diet quality of lactating women in rural Bangladesh. One‐day dietary recall (24‐Hour recall) data of 973 lactating women were obtained from the Bangladesh Integrated Household Survey (BIHS) 2018–2019. Nutrient adequacy was determined using the Estimated Average Requirement (EAR) cut‐point approach. The molar ratios of phytate to zinc, calcium, and iron were calculated. Mean Adequacy Ratio (MAR) was calculated to measure diet quality, and multiple linear regression analysis was performed to assess the sociodemographic determinants of MAR. While the intakes of protein and carbohydrate were equal to/above the Acceptable Macronutrient Distribution Range (AMDR) among most of the subjects, intakes of total energy and fat were below the reference intakes for 74.4% and 98.3%, respectively. Nutrient adequacy remained unmet for riboflavin, calcium, vitamin A, and folate among most (87.2%–97.6%) of the study population, and the mean (SD) MAR was 0.72 (0.12). Cereals were the major contributor of energy and B vitamins, while protein and iron mainly came from plant‐based sources. The molar ratio of phytate to iron was greater than the critical limit among most respondents. Maternal Body Mass Index (BMI) (beta = 0.003, p =.014) and education level (beta = 0.017, p =.038) were associated with their diet quality. The diet of most lactating women in rural Bangladesh indicates the inadequacy of several micronutrients. This can lead to a worsening of the double burden of malnutrition in women. Lactating women should be given special consideration when designing food and nutrition programs for reproductive women in rural Bangladesh. [ABSTRACT FROM AUTHOR]

Snacking recommendations do not exist, yet snacks contribute substantially to daily energy intakes. While dietary intakes of adults in the United States vary by race/ethnicity, little is known about their snacking patterns. The aim of this study was to assess the quality of snacks stratified by race/ethnicity in adults who participated in the 2011–2018 National Health and Nutrition Examination Survey (NHANES). Dietary data from 18,679 adults older than 19 years were assessed to examine differences in intakes from snacking occasions by self-identified race/ethnicity. Mean intakes were estimated for total snacking occasions, percentage of day, nutrient density per 100 kcals, and the average snack. Healthy Eating Index-2015 (HEI) scores were computed for intakes from total day, snack only, and meals only. Analysis of covariance assessed differences between racial/ethnic groups. US Department of Agriculture food categories determined sources of snack foods. Data were weighted to create a nationally representative sample. Asians consumed the least amount of daily energy in the form of snacks, while Blacks and Whites consumed the most. Mean intakes of saturated fats and added sugars consumed during snacking occasions were significantly lowest in Asians, and highest in Blacks and Whites. While total and percentage of daily intakes of sodium were lowest in Asians during snacking occasions, they had significantly lowest meal-only HEI sodium subscore, indicating higher sodium consumption of sodium during mealtimes. Diet quality of snacks varies significantly by race/ethnicity. These data support the need for development of snacking recommendations with culturally appropriate dietary interventions.

Introduction: Dietary intake is considered as a major determinant factor in health maintenance as well as primary and secondary prevention of diseases. The knowledge on the relationship between food nutritional facts and their temperament (Mizaj) can be helpful in the integrative Iranian medicine and modern nutrition approach to individualized diet planning. Material and methods: This study was carried out in three phases using a summative content analysis method: 1) Extraction of the Iranians’ frequent food items through an academic discussion panel of nutritionists and MDs, PhDs of Iranian medicine; 2) Determination of the extracted food items’ temperament and nutritional facts; 3) Statistical analysis of the extracted data using SPSS software. Results: Foods with warm temperament had higher mean levels of energy and polyunsaturated fatty acids as well as iron, zinc, and manganese. On the other hand, the mean values of total fatty acids, cholesterol, vitamin B12, and retinol were significantly higher in wet temperament foods. Additionally, the dryness of food items had a positive significant association with total carbohydrates, fiber, vitamin B6, calcium, iron, magnesium, potassium, copper, and manganese. Finally, wet foods had higher amounts of moisture and vitamin A. Conclusions: The results of the present study revealed that warmness of food items is associated with higher amounts of macronutrients as well as cell growth and proliferation related micronutrients. Moreover, foods with dry temperament had higher amounts of minerals. Further studies, especially food analytical studies, are required to validate the accuracy of aforementioned findings.

Selenium is an essential trace element in humans and animals and its role in selenoprotein and enzyme antioxidant activity is well documented. Food is the principal source of selenium, and it is important that selenium status in the body is adequately maintained for physiological functions. There has been increasing attention on the role of selenium in mitigating the toxic effects of mercury exposure from dietary intake in humans. In contrast, mercury is a neurotoxin, and its continuous exposure can cause adverse health effects in humans. The interactions of selenium and mercury are multi-factorial and involve complex binding mechanisms between these elements at a molecular level. Further insights and understanding in this area may help to evaluate the health implications of dietary mercury exposure and selenium status. This review aims to summarise current information on the interplay of the interactions between selenium and mercury in the body and the protective effect of selenium on at-risk groups in a population who may experience long-term mercury exposure.

Background: Severe obesity (body mass index ≥ 40 kg/m2) and non-communicable diseases, both influenced by diet, have been associated with COVID-19. Genotype-based personalised nutrition advice may improve nutrition knowledge and enhance behaviour change towards better diet quality compared with conventional recommendations. Aim: To investigate the nutrition knowledge, food choices and diet quality in genotyped and non-genotyped individuals during the COVID-19 pandemic. Methods: One hundred and twenty-three healthy UK adults were recruited using convenience sampling through social networks. The online questionnaire consisted of the General Nutrition Knowledge Questionnaire, the Food Choices Questionnaire, and the EPIC-Norfolk Food Frequency Questionnaire (FFQ). FFQ was used to calculate participant diet quality with the Diet Quality Index-International and socio-demographic and anthropometric data. Results: Median general nutrition knowledge, diet variety and diet balance scores were higher in genotyped compared with non-genotyped individuals (71.0 ± 11.0 vs. 61.0 ± 15.0, p = <.001, 18.00 ± 5.00 vs. 15.00 ± 5.00, p =.007 and 2.00 ± 4.00 vs. 0.00 ± 2.00, p =.025, respectively). Pooled sample multiple regression showed that health motive positively influenced while familiarity motive negatively influenced diet quality index scores (β =.428, t = 4.822, p = <.001 and β = –.356, t = –4.021, p =.001, respectively). Conclusions: Nutrition knowledge and diet quality indices of balance and variety were higher among genotyped compared with non-genotyped individuals; overall diet quality was similar between groups. This may be due to pandemic-specific factors, such as altered motives of food choice and availability. [ABSTRACT FROM AUTHOR]

Background The generation of the active form of vitamin B-6, pyridoxal 5′-phosphate (PLP), in tissues is dependent upon riboflavin as flavin mononucleotide, but whether this interaction is important for maintaining vitamin B-6 status is unclear. Objective To investigate vitamin B-6 and riboflavin status, their metabolic interaction, and relationship with methylenetetrahydrofolate reductase (MTHFR) genotype in adulthood. Methods Data from 5612 adults aged 18–102 y were drawn from the Irish National Adult Nutrition Survey (NANS; population-based sample) and the Trinity-Ulster Department of Agriculture (TUDA) and Genovit cohorts (volunteer samples). Plasma PLP and erythrocyte glutathione reductase activation coefficient (EGRac), as a functional indicator of riboflavin, were determined. Results Older (≥65 y) compared with younger (<65 y) adults had significantly lower PLP concentrations (P  < 0.001). A stepwise decrease in plasma PLP was observed across riboflavin categories, from optimal (EGRac ≤1.26), to suboptimal (EGRac: 1.27–1.39), to deficient (EGRac ≥1.40) status, an effect most pronounced in older adults (mean ± SEM: 76.4 ± 0.9 vs 65.0 ± 1.1 vs 55.4 ± 1.2 nmol/L; P  < 0.001). In individuals with the variant MTHFR 677TT genotype combined with riboflavin deficiency, compared with non-TT (CC/CT) genotype participants with sufficient riboflavin, we observed PLP concentrations of 52.1 ± 2.9 compared with 76.8 ±0.7 nmol/L (P  < 0.001). In participants with available dietary data (i.e. NANS cohort, n = 936), PLP was associated with vitamin B-6 intake (nonstandardized regression coefficient β: 2.49; 95% CI 1.75, 3.24; P  < 0.001), supplement use (β: 81.72; 95% CI: 66.01, 97.43; P  < 0.001), fortified food (β: 12.49; 95% CI: 2.08, 22.91; P  = 0.019), and EGRac (β: –65.81; 95% CI: –99.08, –32.54; P  < 0.001), along with BMI (β: –1.81; 95% CI: –3.31, –0.30; P  = 0.019). Conclusions These results are consistent with the known metabolic dependency of PLP on flavin mononucleotide (FMN) and suggest that riboflavin may be the limiting nutrient for maintaining vitamin B-6 status, particularly in individuals with the MTHFR 677TT genotype. Randomized trials are necessary to investigate the PLP response to riboflavin intervention within the dietary range. The TUDA study and the NANS are registered at www.ClinicalTrials.gov as NCT02664584 (27 January 2016) and NCT03374748 (15 December 2017), respectively.

Diet plays a critical role in the development of obesity and obesity-related morbidities. Our study aimed to evaluate the dietary food groups, nutrient intakes and eating behaviors of metabolically healthy and unhealthy obesity phenotypes in an Asian cohort of children and adolescents. Participants (n = 52) were asked to record their diet using a 3-day food diary and intakes were analyzed using a nutrient software. Eating behavior was assessed using a validated questionnaire. Metabolically healthy obesity (MHO) or metabolically unhealthy obesity (MUO) were defined based on criteria of metabolic syndrome. Children/adolescents with MUO consumed fewer whole grains (median: 0.00 (interquartile range: 0.00–0.00 g) vs. 18.5 g (0.00–69.8 g)) and less polyunsaturated fat (6.26% kcal (5.17–7.45% kcal) vs. 6.92% kcal (5.85–9.02% kcal)), and had lower cognitive dietary restraint (15.0 (13.0–17.0) vs. 16.0 (14.0–19.0)) compared to children/adolescents with MHO. Deep fried food, fast food and processed convenience food were positively associated with both systolic (β: 2.84, 95%CI: 0.95–6.62) and diastolic blood pressure (β: 4.83, 95%CI: 0.61–9.04). Higher polyunsaturated fat intake (OR: 0.529, 95%CI: 0.284–0.986) and cognitive dietary restraint (OR: 0.681, 95%CI: 0.472–0.984) were associated with a lower risk of the MUO phenotype. A healthier diet composition and positive eating behavior may contribute to favorable metabolic outcomes in children and adolescents with obesity. [ABSTRACT FROM AUTHOR]

Background: Vitamin B-12 deficiency can result in irreversible neurological damages. It is most prevalent among older adults (∼5-15%), mainly due to impaired absorption. Vitamin B-12 bioavailability varies between food sources, so their importance in preventing deficiency may also vary.Objective: Using the NuAge Database and Biobank, we examined the associations between vitamin B-12 intake - total and by specific food groups - and low vitamin B-12 status and deficiency in older adults.Methods: NuAge included 1753 adults aged 67-84 years followed 4 years. Analytic samples comprised 1230 to 1463 individuals. Dietary vitamin B-12 intake was assessed annually using three 24-hour dietary recalls. Vitamin B-12 status was assessed annually as low serum vitamin B-12 (<221 pmol/L), elevated urinary methylmalonic acid (MMA)/creatinine ratio (>2 µmol/mmol), and a combination of both (deficiency). Vitamin B-12 supplement users were excluded. Multilevel logistic regressions, adjusted for relevant confounders, were used.Results: Across all study years, 21.8-32.5% of participants had low serum vitamin B-12, 12.5-17.0% had elevated urine MMA/creatinine, and 10.1-12.7% had deficiency. Median [IQR] total vitamin B-12 intake was 3.19 [2.31-4.37] µg/day. Main sources were "dairy" and "meat, poultry and organ meats". The ORs (95%CI) in the fifth compared to first quintile of total vitamin B-12 intake for low serum vitamin B-12, elevated urine MMA/creatinine and vitamin B-12 deficiency respectively were 0.52 (0.37-0.75; p-trend < 0.0001), 0.63 (0.37-1.08; p-trend = 0.091), and 0.38 (0.18-0.79; p-trend = 0.006). Similarly, ORs (95%CI) in the fourth compared to first quartile of dairy-derived vitamin B-12 intake were 0.46 (0.32-0.66; p-trend < 0.0001), 0.51 (0.30-0.87; p-trend = 0.006), and 0.35 (0.17-0.73; p-trend = 0.003). No associations were observed with vitamin B-12 from "meat, poultry and organ meats".Conclusion: Higher dietary vitamin B-12 intake, especially from dairy, was associated with decreased risk of low vitamin B-12 status and deficiency in older adults. Food groups might contribute differently at reducing risk of deficiency in older populations. [ABSTRACT FROM AUTHOR]

Frailty is increasingly prevalent worldwide because of aging populations. Diet may play a role as a modifiable risk factor. This study aimed to investigate associations between dietary factors and risk of frailty in the UK Women’s Cohort admitted to hospitals in England. Consumption of foods and nutrients was estimated using a validated 217-item food frequency questionnaire at baseline. Incident frailty was assessed via a hospital frailty risk score based on linkage with hospital episode statistics. Out of 25,186 participants admitted to hospitals, 6919 (27%) were identified with frailty and 10,562 (42%) with pre-frailty over a mean follow-up of 12.7 years. After adjustment for confounding, we observed a 12% increase in risk of frailty with each additional 10 g/MJ intake of total meat (HR = 1.12, 95%CI: 1.07, 1.17), with the highest risk observed for processed meats (HR = 1.45, 95%CI: 1.21, 1.73). Similar associations were observed with pre-frailty. Vegetable intake was associated with slightly lower risk of frailty (HR = 0.98, 95%CI: 0.97, 1.00). There was no evidence of association between most nutrient intakes and in-hospital frailty risk. Overall, our findings suggest that reducing consumption of meat, especially processed meat, in adults may be beneficial regarding the development of frailty.

BackgroundNon-communicable diseases (NCDs) including risk factors, e.g., obesity, are the major causes of preventable deaths in China, yet NCD disparities in China remain under-studied.ObjectiveThis study aimed to compare the determinants and burden of NCDs within four selected provinces in mainland China: the least developed Qinghai-Tibet Plateau group (PG, Tibetan Autonomous Region [TAR] and Qinghai Province) and most developed megacity group (MCG, Shanghai, and Beijing).MethodsStudies, reports, and other official sources with comparable data for NCD burden and related determinants for the four provinces were searched. Geographic, demographic, socioeconomic, and dietary characteristics and selected health indicators (e.g., life expectancy) were extracted from the China Statistical Yearbook and China Health Statistics Yearbook. Data on NCD burdens were extracted from the National Chronic Disease and Risk Factor Surveillance Study and other nationally representative studies.ResultsThe overall NCD mortality rates and prevalence of metabolic risk factors including obesity, hypertension, and diabetes in mainland China have increased in the past 20 years, and this trend is expected to continue. The PG had the highest level of standardized mortality rates (SMRs) on NCDs (711.6–896.1/100,000, 6th/6-level); the MCG had the lowest (290.6–389.6/100,000, 1st/6-level) in mainland China. The gaps in SMRs were particularly high with regard to chronic respiratory diseases (PG 6th/6-level, MCG 1st/6-level) and cardiovascular diseases (6th/6 and 4th/6 in TAR and Qinghai; 1st/6-level and 2nd/6-level in Shanghai and Beijing). In contrast, the prevalence rates of obesity, hypertension, and diabetes were generally higher or comparable in MCG compared to PG. Diabetes prevalence was particularly high in MCG (5th/5-level, 13.36–14.35%) and low in PG (1st/5-level, 6.20–10.39%). However, awareness, treatment, and control of hypertension were poor in PG. Additionally, PG had much lower and severely inadequate intakes of vegetables, fruits, and dairy products, with additional indicators of lower socioeconomic status (education, income, etc.,) compared with MCG.ConclusionEvidence showed large disparities in NCD burden in China's provinces. Socioeconomic disparity and dietary determinants are probably the reasons. Integrated policies and actions are needed.

Advances in the medical field and healthcare sector during the last few decades have resulted in increased longevity. Increased lifespans have in turn led to a rapid global rise of the elderly population. However, ensuring the health and quality of life, especially in the context of chronic age-related ailments, among the growing geriatric population is a challenge. Ageing is associated with several changes in body composition including a decline in the lean body mass usually accompanied by an increase in body fat content which have a bearing on the nutrient requirements for the elderly. The nutrient requirements currently recommended for Indian adults are primarily computed using a factorial approach, that considers the cumulative loss of nutrients and is adjusted for optimal body weights and bioavailability. It is logical that physiological and metabolic changes associated with ageing influence several of these factors: body weight, lean mass, energy expenditure, nutrient retention and bioavailability and thus alter nutrient requirements compared to the adult population. Acknowledging these age-related changes, some international organizations have suggested nutrient requirements specific to the elderly. Given the contextual differences in physiology, caution needs to be exercised in adopting these guidelines for the Indian elderly. In addition, in the Indian context, there is sparse information on the diet and nutrient intakes vis-à-vis nutritional status and physiology of the elderly. This status paper highlights some of the pertinent issues related to nutritional requirements for the elderly that advocate a need for deriving nutritional requirements for the elderly in India.

Research on dietary and other factors associated with dyslipidemia in the United Arab Emirates (UAE) is limited. This study assessed the association of diet, body weight and other risk factors of dyslipidemia by conducting a cross-sectional survey among adults residing in three emirates of the UAE. Validated quantitative food frequency questionnaire and the WHO STEPS Instrument were used to assess dietary intakes, body weight and dyslipidemia-related diagnosis. Composite Mediterranean Diet Score was used to assess adherence to the Mediterranean Diet (MD). Of the 610 participants, dyslipidemia was reported by 23.5% of the 319 participants who ever had blood cholesterol levels measured. Self-reported dyslipidemia was associated with increased age, higher BMI, diabetes, hypertension and cardiovascular disease. Most participants did not meet the recommendations for dietary fiber and calorie intake from saturated fats (61.3% and 81.2%, respectively). Participants with dyslipidemia reported a higher median daily intake of vegetables compared to those without dyslipidemia (p < 0.001), who also showed a significantly higher intake of refined grains and sugar-sweetened beverages (p = 0.008). Participants aged ≥50 years were more likely to have adhered to the MD compared to 18–30-year old participants (OR = 4.16; 95% CI 2.59–6.69). Non-Emiratis had higher odds of adherence to the MD compared to UAE nationals (OR = 1.46; 95%CI 1.04–2.06). Interventions targeting behavioral risk factors of dyslipidemia are warranted.
