Background: Only 9% of individuals in the United Kingdom (UK) meet the recommendation for dietary fibre intake. Little is known about chickpea consumption in the UK. Methods: Chickpea intake trends and sociodemographic patterns were analysed using the National Diet and Nutrition Survey Rolling Programme data collected from 2008/09 to 2018/19 among 15,655 individuals ≥1.5 years completing a four-day food diary. Chickpea consumers were identified based on a list of chickpea-containing foods, with the most consumed foods being hummus, boiled chickpeas, chickpea flour, and low/reduced-fat hummus. Micronutrient and food group intakes were compared between chickpea consumers and non-consumers; the Modified Healthy Dietary Score was also assessed, which measures adherence to UK dietary recommendations. Results: Chickpea consumption increased from 6.1% (2008–2012) to 12.3% (2016–2019). Among 1.5–3 years, consumption increased from 5.7% to 13.4%, and among 19–64 years, consumption increased from 7.1% to 14.4%. The percentage of individuals eating chickpeas was higher among individuals with higher incomes and more education. Healthy-weight adults were more likely to consume chickpeas compared to those who were overweight or obese. Compared to both bean and non-bean consumers, chickpea consumers ate significantly more dietary fibre, fruits and vegetables, pulses, nuts, and less red meat and processed meat products. Chickpea consumers also had a higher Modified Healthy Dietary Score. Conclusions: In the UK, chickpea consumption more than doubled from 2008/09 to 2018/19. Chickpea consumers had a higher diet quality than non-consumers. [ABSTRACT FROM AUTHOR]

Although ultra-processed foods represent more than half of the total energy consumed by the UK population, little is known about the trend in food consumption considering the degree of food processing. We evaluated the trends of the dietary share of foods categorised according to the NOVA classification in a historical series (2018–2019) among the UK population. Data were acquired from the NDNS, a survey that collects diet information through a 4-d food record. We used adjusted linear regression to estimate the dietary participation of NOVA groups and evaluated the linear trends over the years. From 2008 to 2019, we observed a significant increase in the energy share of culinary ingredients (from 3·7 to 4·9 % of the total energy consumed; P -trend = 0·001), especially for butter and oils; and reduction of processed foods (from 9·6 to 8·6 %; P -trend = 0·002), especially for beer and wine. Unprocessed or minimally processed foods (≅30 %, P -trend = 0·505) and ultra-processed foods (≅56 %, P -trend = 0·580) presented no significant change. However, changes in the consumption of some subgroups are noteworthy, such as the reduction in the energy share of red meat, sausages and other reconstituted meat products as well as the increase of fruits, ready meals, breakfast cereals, cookies, pastries, buns and cakes. Regarding the socio-demographic characteristics, no interaction was observed with the trend of the four NOVA groups. From 2008 to 2019 was observed a significant increase in culinary ingredients and a reduction in processed food. Furthermore, it sheds light on the high share of ultra-processed foods in the contemporary British diet. [ABSTRACT FROM AUTHOR]

Body weight regulation may be influenced by the timing of food intake. The relationship between children's BMI and their daily pattern of energy consumption was investigated using data from the UK National Diet and Nutrition Survey 2008–2019. The sample included 6281 children aged 4–18 years. Linear and logistic regression models investigated the timing of energy intake (103 kJ) as a predictor of BMI (kg/m2) and healthy weight status. The models showed that children aged 4–10 years who consume more energy content after 20:00, in comparison with less energy content, had a significantly higher BMI (young girls: β = 0·159; 95 % CI 0·003, 0·315; P = 0·05; young boys: β = 0·166; 95 % CI 0·028, 0·304; P = 0·02). Similar findings were also present for boys aged 11–18 years (β = 0·091; 95 % CI 0·003, 0·180; P = 0·04), though logistic regression findings were contradictory (OR = 0·9566; 95 % CI 0·926, 0·989; P = 0·009). However, older girls who consumed more energy content in the morning had a significantly lower BMI (β = –0·464; 95 % CI –0·655, –0·273; P < 0·001) and a lower probability of non-healthy weight (OR = 0·901; 95 % CI 0·826, 0·982; P = 0·02). Physical activity reduced the likelihood of unhealthy weight status. The data suggest that food consumption later in the day in childhood and into adolescence may increase the risk of a higher BMI, especially for less active children. Developing guidance on appropriate meal timings and recommended energy distribution throughout the day could promote healthier lifestyles. Doing so may help increase parental awareness of timing of food intake and its potential impact on BMI. [ABSTRACT FROM AUTHOR]

We analysed data on 2842 subjects aged ≥40 years enrolled in the National Diet and Nutrition Survey (NDNS 2008–2019). Based on serum 25(OH)D concentrations, study subjects were grouped in three categories: vitamin D deficiency (<25 nmol/L), vitamin D insufficiency (25–49 nmol/L) and vitamin D sufficiency status (≥50 nmol/L). Differences in CVD risk factors between vitamin D deficiency or insufficiency and vitamin D sufficiency status were expressed in standard deviation scores (SDS) and estimated through weighted multiple linear regression models. Key points: Nationally representative data source UK National Diet and Nutrition Survey (2008–2019) is analysed.Vitamin D status is determined according to serum concentration of 25(OH)D deficiency: <25 nmol/L; insufficiency: 25–49 nmol/L; sufficiency: ≥50 nmol/L.Cardiovascular risk factors are compared between individuals with vitamin D deficiency and those with vitamin D sufficiency.Differences are expressed in standard deviation scores.Vitamin D deficiency is associated with a higher cardiovascular risk profile.

Background: Only 9% of individuals in the United Kingdom (UK) meet the recommendation for dietary fibre intake. Little is known about chickpea consumption in the UK. Methods: Chickpea intake trends and sociodemographic patterns were analysed using the National Diet and Nutrition Survey Rolling Programme data collected from 2008/09 to 2018/19 among 15,655 individuals ≥1.5 years completing a four-day food diary. Chickpea consumers were identified based on a list of chickpea-containing foods, with the most consumed foods being hummus, boiled chickpeas, chickpea flour, and low/reduced-fat hummus. Micronutrient and food group intakes were compared between chickpea consumers and non-consumers; the Modified Healthy Dietary Score was also assessed, which measures adherence to UK dietary recommendations. Results: Chickpea consumption increased from 6.1% (2008–2012) to 12.3% (2016–2019). Among 1.5–3 years, consumption increased from 5.7% to 13.4%, and among 19–64 years, consumption increased from 7.1% to 14.4%. The percentage of individuals eating chickpeas was higher among individuals with higher incomes and more education. Healthy-weight adults were more likely to consume chickpeas compared to those who were overweight or obese. Compared to both bean and non-bean consumers, chickpea consumers ate significantly more dietary fibre, fruits and vegetables, pulses, nuts, and less red meat and processed meat products. Chickpea consumers also had a higher Modified Healthy Dietary Score. Conclusions: In the UK, chickpea consumption more than doubled from 2008/09 to 2018/19. Chickpea consumers had a higher diet quality than non-consumers.

Objective: To identify eating occasion-level and individual-level factors associated with the consumption of larger portions in young children and estimate their relative importance. Design: Cross-sectional. Setting: Data from parent-reported 4-d food diaries in the UK National Diet and Nutrition Survey (2008–2017) were analysed. Multilevel models explored variation in eating occasion size (kJ) within (n 48 419 occasions) and between children (n 1962) for all eating occasions. Eating contexts: location, eating companion, watching TV, and sitting at a table and individual characteristics: age, gender, ethnicity and parental socio-economic status were explored as potential correlates of eating occasion size. Participants: Children aged 1·5–5 years. Results: Median eating occasion size was 657 kJ (IQR 356, 1117). Eating occasion size variation was primarily attributed (90 %) to differences between eating occasions. Most (73 %) eating occasions were consumed at home. In adjusted models, eating occasions in eateries were 377 kJ larger than at home. Eating occasions sitting at a table, v. not, were 197 kJ larger. Eating in childcare, with additional family members and friends, and whilst watching TV were other eating contexts associated with slightly larger eating occasion sizes. Conclusions: Eating contexts that vary from one eating occasion to another are more important than demographic characteristics that vary between children in explaining variation in consumed portion sizes in young children. Strategies to promote consumption of age-appropriate portion sizes in young children should be developed, especially in the home environment, in eating contexts such as sitting at the table, eating with others and watching TV.

Recommendations for free sugar intake in the UK should be no more than 5 % of total energy due to increased health risks associated with overconsumption. It was therefore of interest to examine free sugar intakes and associations with health parameters in the UK population. The UK National Diet and Nutrition Survey rolling programme (2008–2017) was used for this study. Dietary intake, anthropometrical measurements and clinical biomarker data collated from 5121 adult respondents aged 19–64 years were statistically analysed. Compared with the average total carbohydrate intake (48 % of energy), free sugars comprised 12·5 %, with sucrose 9 % and fructose 3·5 %. Intakes of these sugars, apart from fructose, were significantly different over collection year (P < 0·001) and significantly higher in males (P < 0·001). Comparing those consuming above or below the UK recommendations for free sugars (5 % energy), significant differences were found for BMI (P < 0·001), TAG (P < 0·001), HDL (P = 0·006) and homocysteine concentrations (P = 0·028), and significant sex differences were observed (e.g. lower blood pressure in females). Regression analysis demonstrated that free sugar intake could predict plasma TAG, HDL and homocysteine concentrations (P < 0·0001), consistent with the link between these parameters and CVD. We also found selected unhealthy food choices (using the UK Eatwell Guide) to be significantly higher in those that consumed above the recommendations (P < 0·0001) and were predictors of free sugar intakes (P < 0·0001). We have shown that adult free sugar intakes in the UK population are associated with certain negative health parameters that support the necessary reduction in free sugar intakes for the UK population.

Abstract Background UK adolescents consume fewer fruits and vegetables and more free sugars than any other age group. Established techniques to understand diet quality can be difficult to use with adolescents because of high participant burden. This study aimed to identify key foods that indicate variation in diet quality in UK adolescents for inclusion in a short food frequency questionnaire (FFQ) and to investigate the associations between adolescent diet quality, nutritional biomarkers and socio-demographic factors. Methods Dietary, demographic and biomarker data from waves 1–8 of the National Diet and Nutrition Survey rolling programme were used (n=2587; aged 11–18 years; 50% boys; n=≤997 biomarker data). Principal component analysis (PCA) was applied to 139 food groups to identify the key patterns within the data. Two diet quality scores, a 139-group and 20-group, were calculated using the PCA coefficients for each food group and multiplying by their standardised reported frequency of consumption and then summing across foods. The foods with the 10 strongest positive and 10 strongest negative coefficients from the PCA results were used for the 20-group score. Scores were standardised to have a zero mean and standard deviation of one. Results The first PCA component explained 3.0% of variance in the dietary data and described a dietary pattern broadly aligned with UK dietary recommendations. A correlation of 0.87 was observed between the 139-group and 20-group scores. Bland-Altman mean difference was 0.00 and 95% limits of agreement were − 0.98 to 0.98 SDs. Correlations, in the expected direction, were seen between each nutritional biomarker and both scores; results attenuated slightly for the 20-group score compared to the 139-group score. Better diet quality was observed among girls, non-white populations and in those from higher socio-economic backgrounds for both scores. Conclusions The diet quality score based on 20 food groups showed reasonable agreement with the 139-group score. Both scores were correlated with nutritional biomarkers. A short 20-item FFQ can provide a meaningful and easy-to-implement tool to assess diet quality in large scale observational and intervention studies with adolescents.

Apparent differences in the adoption of the Dietary Approach to Stop Hypertension (DASH) diet have been reported between less and more educated individuals. However, the mediating role of income has not been clarified. In this study, we aimed at quantifying the mediating effect of income on the relationship between education and the DASH score in the UK population. We analysed data on 4864 subjects aged 18 years and older collected in three waves of the National Diet and Nutrition Survey (2008–2016). The DASH score was calculated using sex-specific quintiles of DASH items. We carried out a counterfactual-based mediation analysis to decompose the total effect of education on DASH score into average direct effect and average causal mediation effect mediated by income. We found that the overall mediating effect of income on the relationship between education and the DASH score was only partial, with an estimated proportion mediated ranging between 6 and 9 %. The mediating effect was higher among females (11·6 %) and younger people (17·9 %). Further research is needed to investigate which other factors may explain the socio-economic inequality in the adoption of the DASH diet in the UK. [ABSTRACT FROM AUTHOR]

Hypovitaminosis D is prevalent worldwide, with many populations failing to achieve the recommended nutrient intake (RNI) for vitamin D (10–20 μg/day). Owing to low vitamin D intakes, limited exposure to ultraviolet-B (UVB) induced dermal synthesis, lack of mandatory fortification and poor uptake in supplement advice, additional food-based strategies are warranted to enable the UK population to achieve optimal vitamin D intakes, thus reducing musculoskeletal risks or suboptimal immune functioning. The aims of the current study were to (1) determine any changes to vitamin D intake and status over a 9-year period, and (2) apply dietary modeling to predict the impact of vitamin D biofortification of pork and pork products on population intakes. Data from the UK National Diet and Nutrition Survey (Year 1–9; 2008/09–2016/17) were analyzed to explore nationally representative mean vitamin D intakes and 25-hydroxyvitamin D (25(OH)D) concentrations (n = 13,350). Four theoretical dietary scenarios of vitamin D pork biofortification were computed (vitamin D content +50/100/150/200% vs. standard). Vitamin D intake in the UK population has not changed significantly from 2008 to 2017 and in 2016/17, across all age groups, 13.2% were considered deficient [25(OH)D

Children's vegetable consumption is generally below national recommendations in the UK. This study examined predictors of vegetable intake by children aged 1·5–18 years using counts and portion sizes derived from 4-d UK National Diet and Nutrition Survey food diaries. Data from 6548 children were examined using linear and logit multilevel models. Specifically, we examined whether demographic variables predicted vegetable consumption, whether environmental context influenced portion sizes of vegetables consumed and which food groups predicted the presence (or absence) of vegetables at an eating occasion (EO). Larger average daily intake of vegetables (g) was predicted by age, ethnicity, equivalised income, variety of vegetables eaten and average energy intake per d (R2 0·549). At a single EO, vegetables were consumed in larger portion sizes at home, with family members and at evening mealtimes (Conditional R2 0·308). Within EO, certain configurations of food groups such as carbohydrates and protein predicted higher odds of vegetables being present (OR 12·85, 95 % CI 9·42, 17·54), whereas foods high in fats, sugars and salt predicted a lower likelihood of vegetable presence (OR 0·03, 95 % CI 0·02, 0·04). Vegetables were rarely eaten alone without other food groups. These findings demonstrate that only one portion of vegetables was eaten per d (median) and this was consumed at a single EO, therefore falling below recommendations. Future research should investigate ways to encourage vegetable intake at times when vegetables are not regularly eaten, such as for breakfast and as snacks, whilst considering which other, potentially competing, foods are presented alongside vegetables.

Milk is the main source of iodine in the UK; however, the consumption and popularity of plant-based milk-alternative drinks are increasing. Consumers may be at risk of iodine deficiency as, unless fortified, milk alternatives have a low iodine concentration. We therefore aimed to compare the iodine intake and status of milk-alternative consumers with that of cows' milk consumers. We used data from the UK National Diet and Nutrition Survey from years 7 to 9 (2014–2017; before a few manufacturers fortified their milk-alternative drinks with iodine). Data from 4-d food diaries were used to identify consumers of milk-alternative drinks and cows' milk, along with the estimation of their iodine intake (µg/d) (available for n 3976 adults and children ≥1·5 years). Iodine status was based on urinary iodine concentration (UIC, µg/l) from spot-urine samples (available for n 2845 adults and children ≥4 years). Milk-alternative drinks were consumed by 4·6 % (n 185; n 88 consumed these drinks exclusively). Iodine intake was significantly lower in exclusive consumers of milk alternatives than cows' milk consumers (94 v. 129 µg/d; P < 0·001). Exclusive consumers of milk alternatives also had a lower median UIC than cows' milk consumers (79 v. 132 µg/l; P < 0·001) and were classified as iodine deficient by the WHO criterion (median UIC < 100 µg/l), whereas cows' milk consumers were iodine sufficient. These data show that consumers of unfortified milk-alternative drinks are at risk of iodine deficiency. As a greater number of people consume milk-alternative drinks, it is important that these products are fortified appropriately to provide a similar iodine content to that of cows' milk.

Little is known on the association between frequency of yogurt consumption and dietary intake in the United Kingdom (UK). The aim of the present study was to examine associations between frequency of yogurt consumption and dietary outcomes in children (n 1912, age 9⋅6 ± 0⋅1 years, 51 % boys) and adults (n 2064, age 48⋅7 ± 0⋅5 years, 49 % men) using cross-sectional data from the National Diet and Nutrition Survey rolling programme year 7 to year 9 (2014/15–2016/17). The frequency of yogurt consumption was determined by the number of days with yogurt reported in 4-d food diaries and participants were classified as non-eaters, occasional eaters (1–2 d of consumption) or regular eaters (3–4 d of consumption). Dietary outcomes were estimated from food diaries. The frequency of yogurt consumption was positively associated with intake of key vitamins and minerals such as thiamin, riboflavin, vitamin C, potassium, calcium, magnesium, phosphorus and iodine in both children and adults (all P < 0⋅0018), as well as higher intake of total dairy (P < 0⋅0001 for both children and adults). Regular yogurt eaters were more likely to meet or exceed nutrient recommendations for vitamins and minerals such as vitamin A, riboflavin, folate, potassium, calcium, magnesium, zinc and iodine (all P < 0⋅001). Diet quality was positively associated with frequency of yogurt consumption in children (P = 0⋅045) and adults (P < 0⋅001). No association between yogurt consumption and free sugar intake was found (P = 0⋅49 for children and P = 0⋅29 for adults). The study suggests that frequency of yogurt consumption is associated with better dietary intake and diet quality in children and adults in the UK.

The Dietary Approaches to Stop Hypertension (DASH) diet is an effective measure in the prevention and treatment of CVD. We evaluated recent trends in socio-economic differences in the DASH score in the UK population, using education, occupation and income as proxies of socio-economic position (SEP). We analysed data on 6416 subjects aged 18 years and older collected in the National Diet and Nutrition Survey (2008–2016). The DASH score was calculated using sex-specific quintiles of DASH items. Multiple linear regression and quantile regression models were used to evaluate the trend in DASH score according to SEP. The mean DASH score was 24 (sd 5). The estimated mean difference between people with no qualification and those having the highest level of education was −3·61 (95 % CI −4·00, −3·22) points. The mean difference between subjects engaged in routine occupations and those engaged in high managerial and professional occupations was −3·41 (95 % CI −3·89, −2·93) points and for those in the first fifth and last fifth of the household income distribution was −2·71 (95 % CI −3·15, −2·28) points. DASH score improved over time, and no significant differences in the trend were observed across SEP. The widest socio-economic differences emerged for consumption of fruit, vegetables, whole grains, nuts, seeds and legumes. Despite an overall increase in the DASH score, a persisting SEP gap was observed. This is an important limiting factor in reducing the high socio-economic inequality in CVD observed in the UK.

Vitamin D status is relatively poor in the general population, potentially leading to various conditions. The present study evaluates the relationship between vitamin D status and intake in the UK population and the impact of vitamin D fortified ready-to-eat cereals (RTEC) on this status via data from the National Diet and Nutrition Survey (NDNS: 2008–2012). Four cohorts were addressed: ages 4–10 (n = 803), ages 11–18 (n = 884), ages 19–64 (n = 1655) and ages 65 and higher (n = 428). The impact of fortification by 4.2 μg vitamin D per 100 g of RTEC on vitamin D intake and status was mathematically modelled. Average vitamin D daily intake was age-dependent, ranging from ~2.6 (age range 4–18 years) to ~5.0 μg (older than 64 years). Average 25(OH)D concentration ranged from 43 to 51 nmol/L, the highest in children. The relationship between vitamin D intake and status followed an asymptotic curve with a predicted plateau concentration ranging from 52 in children to 83 nmol/L in elderly. The fortification model showed that serum concentrations increased with ~1.0 in children to ~6.5 nmol/L in the elderly. This study revealed that vitamin D intake in the UK population is low with 25(OH)D concentrations being suboptimal for general health. Fortification of breakfast cereals can contribute to improve overall vitamin D status.

The contribution of 100% fruit juice (FJ) to the total daily intakes of energy, sugars, and select vitamins and minerals and to the recommended dietary allowances (RDAs) or adequate intake (AI) of these micronutrients was assessed in individuals reporting the consumption of 100% FJ in the national dietary intake surveys of the United States (U.S.; n = 8661), the United Kingdom (UK; n = 2546) and Brazil (n = 34,003). Associations of 100% FJ intake with the odds of being overweight or obese also were assessed. Data from the U.S. National Health and Nutrition Examination Survey (2013–2014), the UK National Diet and Nutrition Survey (2012–2014), and Brazil’s Pesquisa de Orçamentos Familiares (2008–2009) were used, and all analyses were limited to individuals reporting consumption of 100% FJ on at least one day of the dietary intake survey. Approximately 34%, 37%, and 42% of individuals surveyed reported the consumption of 100% FJ on at least one day of the dietary intake survey in the U.S., UK, and Brazil, respectively, and the average daily intakes of 100% FJ were 184 g, 130 g, and 249 g, respectively. Across the 3 countries, 100% FJ contributed to 3–6% of total energy intakes, 12–31% of total sugar intakes, 21–54% of total vitamin C intakes, 1–12% of total vitamin A intakes, 4–15% of total folate intakes, 7–17% of total potassium intakes, 2–7% of total calcium intakes, and 4–12% of total magnesium intakes. In a multivariate logistic regression model, juice intake was associated with a significant reduction in the odds of being overweight or obese in UK adults (OR = 0.79; 0.63, 0.99), and significant increases in the odds of being overweight or obese in UK children (OR = 1.16; 1.01, 1.33) and Brazilian adults (OR = 1.04; 1.00, 1.09). Nutrient contributions of 100% FJ vary according to regional intake levels. In all three countries studied, 100% FJ contributed to more than 5% of the RDAs for vitamin C and folate. In the U.S. and Brazil, 100% FJ contributed to more than 5% of the RDA for magnesium and more than 5% of the AI for potassium.

Objective: To test whether diets achieving recommendations from the UK's Scientific Advisory Committee on Nutrition (SACN) were associated with higher monetary costs in a nationally representative sample of UK adults.Design: A cross-sectional study linking 4 d diet diaries in the National Diet and Nutrition Survey (NDNS) to contemporaneous food price data from a market research firm. The monetary cost of diets was assessed in relation to whether or not they met eight food- and nutrient-based recommendations from SACN. Regression models adjusted for potential confounding factors. The primary outcome measure was individual dietary cost per day and per 2000 kcal (8368 kJ).Setting: UK.Subjects: Adults (n 2045) sampled between 2008 and 2012 in the NDNS.Results: On an isoenergetic basis, diets that met the recommendations for fruit and vegetables, oily fish, non-milk extrinsic sugars, fat, saturated fat and salt were estimated to be between 3 and 17 % more expensive. Diets meeting the recommendation for red and processed meats were 4 % less expensive, while meeting the recommendation for fibre was cost-neutral. Meeting multiple targets was also associated with higher costs; on average, diets meeting six or more SACN recommendations were estimated to be 29 % more costly than isoenergetic diets that met no recommendations.Conclusions: Food costs may be a population-level barrier limiting the adoption of dietary recommendations in the UK. Future research should focus on identifying systems- and individual-level strategies to enable consumers achieve dietary recommendations without increasing food costs. Such strategies may improve the uptake of healthy eating in the population. [ABSTRACT FROM AUTHOR]

The aim of this study was to examine empirical dietary patterns in UK adults and their association with sociodemographic characteristics, lifestyle factors, self-reported nutrient intake, nutrient biomarkers, and the Nutrient-based Diet Quality Score (NDQS) using National Diet and Nutrition Survey data 2008-2012 (n = 2083; mean age 49 years; 43.3% male). Four patterns explained 13.6% of the total variance: 'Snacks, fast food, fizzy drinks' (SFFFD), 'Fruit, vegetables, oily fish' (FVOF), 'Meat, potatoes, beer' (MPB), and 'Sugary foods, dairy' (SFD). 'SFFFD' was associated positively with: being male; smoking; body mass index (BMI); urinary sodium; intake of non-milk extrinsic sugars (NMES), fat and starch; and negatively with: age; plasma carotenoids; and NDQS. 'FVOF' was associated positively with: being non-white; age; income; socioeconomic classification (National Statistics Socio-economic Classifications; NSSEC); plasma carotenoids; intake of non-starch polysaccharides and polyunsaturated fatty acids. It was negatively associated with: being male, smoking, BMI, urinary sodium, intake of saturated fat; and NMES and NDQS. Whilst the patterns explained only 13.6% of the total variance, they were associated with self-reported nutrient intake, biomarkers of nutrient intake, sociodemographic and lifestyle variables, and the NDQS. These findings provide support for dietary patterns analyses as a means of exploring dietary intake in the UK population to inform public health nutrition policy and guidance. [ABSTRACT FROM AUTHOR]

The UK government's National Diet and Nutrition Survey report of Years 5 and 6 (2012/2013-2013/2014) of the Rolling Programme has just been published. By and large, the results are not encouraging. Compared to previous results from 2008/2009, little has changed and the national sample of children and adults continues to report eating too much saturated fat, non-milk extrinsic sugars, too few fruit and vegetables and not enough oil-rich fish, with certain groups of the population found to have low levels of some key vitamins and minerals. A glimmer of hope is that there are a couple of indicators of improvement, and overall, the UK population's diet has not got worse in the past 6 years. [ABSTRACT FROM AUTHOR]

An energy-dense, high-fat, low-fibre dietary pattern has been prospectively associated with the development of obesity in childhood but is population-specific, which limits translating the pattern into interventions. We explored the generalisability and correlates of this obesogenic dietary pattern in the UK National Diet and Nutrition Survey (NDNS) for the first time. Data came from participants (n = 4636 children and n = 4738 adults) with 4-day food diaries in NDNS 2008–2014. Reduced rank regression was applied to 51 food groups to explain variation in energy density, fibre and fat intake. Consistency of the pattern in population subgroups (according to sex, age, occupation and income) was compared with the whole sample pattern using coefficients of congruence (COC). Pattern correlates (sociodemographic, survey year, physical activity and eating related behaviours) were explored using multiple linear regression. Food group loadings were similar to the previously identified obesogenic dietary pattern and were generalisable across all sub-groups (COC: 0.93–0.99). An obesogenic diet was associated with eating takeaways, being omnivorous, a manual household occupation and lower household income in both adults and children (p < 0.0001). Dieting for weight loss, being older, more physically active and less sedentary was associated with a less obesogenic diet among adults (p < 0.0001). Future experimental studies should investigate if changes in this obesogenic pattern could be used to monitor the effectiveness of obesity prevention policies or develop personalised interventions.

The aim of this study was to examine empirical dietary patterns in UK adults and their association with sociodemographic characteristics, lifestyle factors, self-reported nutrient intake, nutrient biomarkers, and the Nutrient-based Diet Quality Score (NDQS) using National Diet and Nutrition Survey data 2008–2012 (n = 2083; mean age 49 years; 43.3% male). Four patterns explained 13.6% of the total variance: ‘Snacks, fast food, fizzy drinks’ (SFFFD), ‘Fruit, vegetables, oily fish’ (FVOF), ‘Meat, potatoes, beer’ (MPB), and ‘Sugary foods, dairy’ (SFD). ‘SFFFD’ was associated positively with: being male; smoking; body mass index (BMI); urinary sodium; intake of non-milk extrinsic sugars (NMES), fat and starch; and negatively with: age; plasma carotenoids; and NDQS. ‘FVOF’ was associated positively with: being non-white; age; income; socioeconomic classification (National Statistics Socio-economic Classifications; NSSEC); plasma carotenoids; intake of non-starch polysaccharides and polyunsaturated fatty acids. It was negatively associated with: being male, smoking, BMI, urinary sodium, intake of saturated fat; and NMES and NDQS. Whilst the patterns explained only 13.6% of the total variance, they were associated with self-reported nutrient intake, biomarkers of nutrient intake, sociodemographic and lifestyle variables, and the NDQS. These findings provide support for dietary patterns analyses as a means of exploring dietary intake in the UK population to inform public health nutrition policy and guidance.

This study investigated the cross-sectional association between an anti-inflammatory and anti-oxidant dietary pattern and diabetes in the national diet and nutrition survey (NDNS) rolling programme years 1–4. A total of 1531 survey members provided dietary data. Reduced Rank Regression (RRR) was used to derive an anti-inflammatory and anti-oxidant dietary pattern. Serum C-reactive protein (CRP) and plasma carotenoids were selected as response variables and markers of inflammation and antioxidant status, respectively. Overall, 52 survey members had diabetes. The derived anti-inflammatory and anti-oxidant dietary pattern was inversely related to CRP and positively to carotenoids. It was associated with lower odds of diabetes (multivariate adjusted OR for highest compared with lowest quintile: 0.17; 95%CI: 0.04–0.73;pfor linear trend = 0.013). In conclusion, an anti-inflammatory and anti-oxidant dietary pattern is inversely related to diabetes. Further research is required to understand the overall framework within which foods and nutrients interact to affect metabolic pathways related to diabetes risk. [ABSTRACT FROM AUTHOR]

Background: More than one-fifth of the United Kingdom population has poor vitamin D status (serum 25-hydroxyvitamin D [25(OH)D] concentration <25 nmol/L), particularly individuals with low sun exposure or poor dietary intake. Objective: We identified the fortification vehicle and concentration most likely to safely increase population vitamin D intakes and vitamin D status. Design: Wheat flour and milk were identified as primary fortification vehicles for their universal consumption in population groups most at risk of vitamin D deficiency including children aged 18–36 mo, females aged 15–49 y, and adults aged ≥65 y. With the use of data from the first 2 y (2008–2010) of the National Diet and Nutrition Survey Rolling Program, we simulated the effect of fortifying wheat flour and milk with vitamin D on United Kingdom food consumption. Empirically derived equations for the relation between vitamin D intake and the serum 25(OH)D concentration were used to estimate the population serum 25(OH)D concentration for each fortification scenario. Results: At a simulated fortification of 10 mg vitamin D/100 g wheat flour, the proportion of at-risk groups estimated to have vitamin D intakes below United Kingdom Reference Nutrient Intakes was reduced from 93% to 50%, with no individual exceeding the United Kingdom Tolerable Upper Intake Level; the 2.5th percentile of the population winter serum 25(OH)D concentration rose from 20 to 27 nmol/L after fortification. The simulation of the fortification of wheat flour at this concentration was more effective than that of the fortification of milk (at concentrations between 0.25 and 7 mg vitamin D/ 100 L milk) or of the fortification of milk and flour combined. Conclusion: To our knowledge, this study provides new evidence that vitamin D fortification of wheat flour could be a viable option for safely improving vitamin D intakes and the status of United Kingdom population groups at risk of deficiency without increasing risk of exceeding current reference thresholds.

Socio-economic differences in diet are a potential contributor to health inequalities. The present study provides an up-to-date picture of socio-economic differences in diet in the UK, focusing on the consumption of three food groups and two nutrients of public health concern: fruit and vegetables; red and processed meat; oily fish; saturated fats; non-milk extrinsic sugars (NMES). We analysed data for 1491 adults (age ≥ 19 years) from the National Diet and Nutrition Survey 2008–2011. Socio-economic indicators were household income, occupational social class and highest educational qualification. Covariate-adjusted estimates for intakes of fruit and vegetables, red and processed meat, and both nutrients were estimated using general linear models. Covariate-adjusted OR for oily fish consumption were derived with logistic regression models. We observed consistent socio-economic gradients in the consumption of the three food groups as estimated by all the three indicators. Contrasting highest and lowest levels of each socio-economic indicator, we observed significant differences in intakes for the three food groups and NMES. Depending on the socio-economic indicator, highest socio-economic groups consumed up to 128 g/d more fruit and vegetables, 26 g/d less red and processed meat, and 2·6 % points less NMES (P< 0·05 for all). Relative to lowest socio-economic groups, highest socio-economic groups were 2·4 to 4·0 times more likely to eat oily fish. No significant patterns in saturated fat consumption were apparent. In conclusion, socio-economic differences were identified in the consumption of food groups and one nutrient of public health importance. Aligning dietary intakes with public health guidance may require interventions specifically designed to reduce health inequalities. [ABSTRACT FROM PUBLISHER]

Fruit and vegetables make an important contribution to health, partly due to the composition of phytonutrients, such as carotenoids and polyphenols. The aim of the present study was to quantify the intake of fruit and vegetables across different European countries using food consumption data of increasing complexity: food balance sheets (FBS); the European Food Safety Authority (EFSA) Comprehensive Database; individual food consumption data from the UK National Diet and Nutrition Survey (NDNS). Across Europe, the average consumption of fruit and vegetables ranged from 192 to 824 g/d (FBS data). Based on EFSA data, nine out of fourteen countries consumed < 400 g/d (recommended by the WHO), although even in the highest-consuming countries such as Spain, 36 % did not reach the target intake. In the UK, the average consumption of fruit and vegetables was 310 g/d (NDNS data). Generally, phytonutrient intake increased in accordance with fruit and vegetable intake across all European countries with the exception of lycopene (from tomatoes), which appeared to be higher in some countries that consumed less fruit and vegetables. There were little differences in the average intake of flavanols, flavonols and lycopene in those who did or did not meet the 400 g/d recommendation in the UK. However, average intakes of carotenoid, flavanone, anthocyanidin and ellagic acid were higher in those who consumed >400 g/d of fruit and vegetables compared with those who did not. Overall, intakes of phytonutrients are highly variable, suggesting that while some individuals obtain healthful amounts, there may be others who do not gain all the potential benefits associated with phytonutrients in the diet.

Food composition tables require updating regularly to keep abreast of the periodic reformulation of fortified foods and dietary supplements. This paper describes a process undertaken to update the vitamin D content of fortified foods and supplements consumed in the UK, and the impact this may have on reported vitamin D intake. In 2011, the vitamin D content of the 289 vitamin D fortified foods and vitamin D containing supplements recorded in the N ational D iet and N utrition S urvey ( NDNS) Nutrient Databank (last updated in 2008) was compared to data from industry websites, trade associations and manufacturers, and nutrition labelling on pack. Typical 'overages' (the additional amount added to account for any processing loss or degradation) applied during vitamin D fortification were also obtained. This information was used to update the NDNS Nutrient Databank, and applied to NDNS food consumption data (2008/2010) to determine the impact of the composition update on reported population vitamin D intakes. Up-to-date vitamin D values were obtained for 257 (89%) of the 289 items in the NDNS databank; the remainder were no longer available on the market. The vitamin D content of 31 (11%) of the items had changed, and these were most commonly breakfast cereals, fat spreads and powdered malt drinks. A further eight food items were identified as newly fortified with vitamin D. Calculation of mean vitamin D intakes using updated data identified that use of out-of-date food composition data may lead to an underestimation of UK vitamin D intakes of around 3% (0.1 μg/day). When a blanket 12.5% 'overage' was applied to all items, this underestimate increased to 6% (0.2 μg/day). Even though the absolute impact of updating the vitamin D content of fortified foods and supplements on population mean intakes is relatively small, our analysis suggests it is important that nutrient databases are regularly updated. The new estimates of the vitamin D content of foods and supplements should be used for future estimates of vitamin D intake in the UK until a further periodic update is conducted.

Toddlers and young children in the second and third years of life (12-35 months) may be nutritionally vulnerable, especially if they eat a limited range of foods or consume a diet that is energy rich but nutrient poor. We compared dietary intakes among children aged 18-35 months from the Na tional D iet and N utrition S urvey (2008-2011) and children aged 12-18 months from the D iet and N utrition S urvey of I nfants and Y oung C hildren (2011) with UK Dietary Reference Values ( DRVs) to assess potential nutrient excess or inadequacy. Multiple criteria were used [reference nutrient intake ( RNI), estimated average requirements ( EAR) and lower reference nutrient intake ( LRNI)], and where the LRNI or EAR were unavailable they were estimated as 75% of the EAR or RNI, respectively. Compared to current recommendations, there appear to be significant shortfalls in intakes of vitamin D in young children in the UK, and supplementation, although recommended by government, is not addressing the problem because take-up is low (9-11%). Vitamin D intakes (including supplements) averaged only 55% of the RNI among children aged 12-18 months and 33% of the RNI for those aged 18-35 months, while 64% and 87% of the younger and older group, respectively, had intakes below the LRNI (estimated). Endogenous synthesis of vitamin D may be insufficient to fulfil requirements, especially in winter. Iron intakes are also suboptimal among some groups. Based on the EAR cut-point method, the estimated population prevalence of dietary inadequacy for children aged 18-35 months was 91% for vitamin D and 31% for iron. Zinc, vitamin A and iodine had estimated levels of dietary inadequacy ranging from 5% to 19%. Mean energy intakes were below the 1991 DRV for energy but above the most recent DRV issued in 2011, while protein intakes in both surveys were in excess of the RNI. Further work is warranted to identify dietary patterns associated with low micronutrient intakes and status, and to assess the best strategies for ensuring adequacy, especially among vulnerable groups. Parents and healthcare professionals should be informed as to how to minimise the risks of both nutrient deficiency and excessive energy intakes for the young children in their care. Government can facilitate provision of appropriate advice via the healthcare system and encourage provision of appropriate foods and supplements via enabling legislation. The food industry also has a role in the responsible provision of fortified foods and drinks that can address nutrient inadequacy. [ABSTRACT FROM AUTHOR]

ObjectiveConcern has recently been expressed about Pb levels in Pb-shot game meat. Our aim was to determine the consumption of game birds in a representative sample population in the UK, and in children and women of childbearing age in particular.DesignPopulation-based cross-sectional cohort study. Data from 4 d diet diaries from the UK National Diet and Nutrition Survey (NDNS; 2008–2010) were extracted to analyse data on game bird consumption in the sample population, in women of childbearing age (15–45 years old) and in children ≤6 years old.SettingHome-based study in representative areas of the UK.SubjectsParticipants in the NDNS (2008–2010; n 2126, age 1·5 to >65 years).ResultsFifty-eight participants (2·7 %) reported eating game birds. The mean intake was 19·5 (sd 18·1) g/d (median 15·6, range 1·3–92·9 g/d). In women of childbearing age (15–45 years), 11/383 (2·9 %) reported eating game birds, with a mean intake of 22·4 (sd 25·8) g/d (median 15·6, range 2·0–92·9 g/d). In children aged ≤6 years old, 3/342 (0·9 %) were reported as eating game birds, with a mean intake of 6·8 (sd 9·7) g/d (median 2·4, range 1·3–23·2 g/d).ConclusionsThe prevalence of consumption of game birds by women of childbearing age and children ≤6 years old was relatively low and intakes were small. However, any exposure to Pb in these two groups is undesirable. As are uncertainties about the ability of the diet diary method to capture the consumption of food items that are infrequently consumed, alternative methods of capturing these data should be used in future studies.

Total potato consumption has been declining slowly in the UK at a rate of about 1-2% per year, in tandem with an increase in consumption of other starchy staples such as pasta and rice. Consumers and even health professionals often have a negative perception of potatoes and of chips in particular. We have evaluated the nutritional contribution of potatoes and potato products to the British diet by a secondary analysis of four-day dietary records from the National Diet and Nutrition Survey 2008-2011, and distinguished between consumption of fried chips and oven chips. We also calculated portion sizes of six different types of potato dishes [oven chips, fried chips, boiled potatoes, mashed potatoes, roast potatoes and jacket (baked) potatoes]. Over 92% of respondents consumed potatoes during the four-day survey, 27% consumed oven chips and 41% consumed fried chips. Potatoes (including chips) contributed 7% of total energy, but greater proportions of potassium and vitamin B6 (15%), vitamin C (14%), fibre (13%), folate (10%) and magnesium (9%). On the other hand, they contributed only 4% of saturated fatty acids. Per capita consumption of potatoes averaged 85 g/day, of which, fried chips contributed 20 g/day and oven chips 10 g/day. For fried chips, mean portion size per occasion was 149 g among adults, 138 g among teenagers and 94 g among 4- to 10-year-olds, while portion sizes for oven chips were slightly smaller. Potatoes can increase the nutrient density of the diet by providing a relatively high micronutrient contribution, compared with energy content, while delivering only modest amounts of saturated fatty acid and sodium. Reformulation to remove trans fatty acids and reduce saturated fatty acid and salt has improved the nutritional profile of some potato products. Still, there may be scope in catering establishments to offer smaller portions, thicker chips and more oven-baked potato products. Nutritionally, potatoes and potato products should be seen as a white vegetable, whose consumption should be encouraged alongside other, coloured, vegetables. [ABSTRACT FROM AUTHOR]

Despite being a staple food in the UK for centuries, bread consumption has fallen steadily over the last few decades. Average consumption now equates to only around 2-3 slices of bread a day. As well as providing energy, mainly in the form of starch, bread contains dietary fibre and a range of vitamins and minerals. The National Diet and Nutrition Survey (NDNS) of adults suggests that it still contributes more than 10% of our daily intake of protein, thiamine, niacin, folate, iron, zinc, copper and magnesium; one-fifth of our fibre and calcium intakes; and more than one-quarter of our manganese intake. Therefore, eating bread can help consumers to meet their daily requirements for many nutrients, including micronutrients for which there is evidence of low intake in some groups in the UK, such as zinc and calcium. This paper gives an overview of the role of bread in the UK diet, its contribution to nutrient intakes and current consumption patterns in different population groups. [ABSTRACT FROM AUTHOR]

High saturated fat intake is an established risk factor for several chronic diseases. The objective of the present study is to report dietary intakes and main food sources of fat and fatty acids (FA) from the first year of the National Diet and Nutrition Survey (NDNS) rolling programme in the UK. Dietary data were collected using 4 d estimated food diaries (n 896) and compared with dietary reference values (DRV) and previous NDNS results. Total fat provided 34–36 % food energy (FE) across all age groups, which was similar to previous surveys for adults. Men (19–64 years) and older girls (11–18 years) had mean intakes just above the DRV, while all other groups had mean total fat intakes of < 35 % FE. SFA intakes were lower compared with previous surveys, ranging from 13 to 15 % FE, but still above the DRV. Mean MUFA intakes were 12·5 % FE for adults and children aged 4–18 years and all were below the DRV. Mean n-3 PUFA intake represented 0·7–1·1 % FE. Compared with previous survey data, the direction of change for n-3 PUFA was upwards for all age groups, although the differences in absolute terms were very small. Trans-FA intakes were lower than in previous NDNS and were less than 2 g/d for all age groups, representing 0·8 % FE and lower than the DRV in all age groups. In conclusion, dietary intake of fat and FA is moving towards recommended levels for the UK population. However, there remains room for considerable further improvement. [ABSTRACT FROM PUBLISHER]

Background: Eating context is the immediate environment of each eating occasion (EO). There is limited knowledge on the effects of the eating context on food consumption in children, due to the difficulty in measuring the multiple eating contexts children experience throughout the day. This study applied ecological momentary assessment using food diaries to explore the relationships between eating context and fruit and vegetable consumption in UK children. Methods: Using 4 d unweighed food diaries, data were collected for 642 children aged 1.5-10y in two years of the UK National Diet and Nutrition Survey (2008-2010). Participants recorded all foods and drinks consumed at each EO, where and with whom the food was consumed, whether the TV was on and if eaten at a table. Mixed logistic regression and mixed multinomial logistic regression were used to calculate associations between eating contexts and fruit and vegetables (FV) consumed by quartiles. Results: Of 16,840 EOs, 73% took place at home and 31% with parents only. Frequency of eating alone and with friends increased with age. Compared to eating at home, children aged 1.5-3y were more likely to consume fruit at care outside home (>10-50g OR:2.39; >50-100g OR:2.12); children aged 4-6y were more likely to consume fruit (>50-100g OR:3.53; >100g OR:1.88) and vegetables at school (>30-60g OR:3.56). Compared to eating with parents only, children aged 1.5-3y were more likely to consume fruit with friends (>10-50g OR:2.69; >50-100g OR:3.49), and with carer and other children/others (>10-50g OR:2.25); children aged 4-6y were more likely to consume fruit (>50-100g OR:1.96) and vegetables with friends (>30-60g OR:3.56). Children of all ages were more likely to eat vegetables when the TV was off than on and at a table than not at table. Conclusions: The use of food diaries to capture multiple eating contexts and detailed fruit and vegetable consumption data was demonstrated at a population level. Higher odds of FV consumption were seen from structured settings such as school and care outside home than at home, as well as when eating at a table and the TV off. This study highlights eating contexts where provision of fruit and vegetables could be improved, especially at home. Future research should take eating context into consideration when planning interventions to target children's food consumption and eating behaviour. [ABSTRACT FROM AUTHOR]

The National Diet and Nutrition Survey (NDNS) is a cross-sectional survey designed to gather data representative of the UK population on food consumption, nutrient intakes and nutritional status. The objectives of the present paper were to identify and describe food consumption and nutrient intakes in the UK from the first year of the NDNS rolling programme (2008–09) and compare these with the 2000–01 NDNS of adults aged 19–64 years and the 1997 NDNS of young people aged 4–18 years. Differences in median daily food consumption and nutrient intakes between the surveys were compared by sex and age group (4–10 years, 11–18 years and 19–64 years). There were no changes in energy, total fat or carbohydrate intakes between the surveys. Children aged 4–10 years had significantly lower consumption of soft drinks (not low calorie), crisps and savoury snacks and chocolate confectionery in 2008–09 than in 1997 (all P < 0·0001). The percentage contribution of non-milk extrinsic sugars to food energy was also significantly lower than in 1997 in children aged 4–10 years (P < 0·0001), contributing 13·7–14·6 % in 2008–09 compared with 16·8 % in 1997. These changes were not as marked in older children and there were no changes in these foods and nutrients in adults. There was still a substantial proportion (46 %) of girls aged 11–18 years and women aged 19–64 years (21 %) with mean daily Fe intakes below the lower reference nutrient intake. Since previous surveys there have been some positive changes in intakes especially in younger children. However, further attention is required in other groups, in particular adolescent girls.

The first results from the new rolling programme of the UK's National Diet and Nutrition Survey (NDNS) have been published. The survey found that breakfast cereals were consumed by about 50% of those children and adults taking part, and the average amount eaten was generally in line with the recommendations by the European breakfast cereal association on portion size. Breakfast cereals provided only a small proportion of the total intake of fat, saturated fat, non-milk extrinsic sugars and sodium, as well as contributing useful amounts of fibre (as measured by non-starch polysaccharides). Similarities regarding breakfast cereals and their contribution to the UK diet were seen with this survey and the recent Low Income Diet and Nutrition Survey. [ABSTRACT FROM AUTHOR]

Objective:To disaggregate composite food codes used in the UK National Diet and Nutrition Survey (NDNS) into their individual food components in order to provide a more complete estimate of intake at the individual food level.Methods:A total of 3216 composite food codes from the NDNS food composition databank were subject to disaggregation. The main food components used were meat, fish, fruit, vegetables and cheese, which were further divided into 26 subcategories.Results:It was shown that previous determination of meat containing composite food codes provided an overestimate of meat intake and underestimate of additional components such as fruit and vegetables.Conclusions:By incorporating disaggregated data into NDNS, variations will be seen in consumption of some main food groups, but these variations may be also attributable to trends in consumption.

The first results of the new National Diet and Nutrition Survey (NDNS) rolling programme were published in February 2010. The results provide insight into current trends in food consumption and nutrient intakes for children (18 months to 18 years) and adults (19–64 years) in the UK. This paper reviews the survey methodology used for the rolling programme as it differs to that of previous surveys, and also examines the preliminary findings for foods and nutrients most relevant to public health nutrition, such as fruit and vegetable and fat intake. While it appears that some progress is being made towards the recommendations and guidelines for healthy eating, further progress is required to improve the nation's diet and health.

The National Diet and Nutrition Survey (NDNS) of adults aged 19–64 years, carried out in 2000–1, is part of the NDNS programme, a series of cross-sectional surveys aiming to provide detailed quantitative information on the diet, nutritional status and related characteristics of the British population. The programme is split into four surveys of different population age-groups, conducted at approximately three-yearly intervals. In the survey of adults food consumption data were collected from 1724 respondents using a 7 d weighed-intake dietary record. Other components included: height, weight, waist and hip circumference and blood pressure measurements; a 24 h urine sample; a blood sample; a record of physical activity. Results have been published in four volumes covering food consumption, energy and macronutrient intakes, micronutrient intakes and nutritional status, including physical measurements and physical activity. The results have shown that, based on a comparison of nutrient intakes with the UK dietary reference values, adults in Britain are generally getting sufficient nutrients from their diets. However, younger adults (particularly women) and those in lower socio-economic groups are more likely to have low micronutrient intakes and lower levels of some nutritional status indices. The proportion of food energy derived from total fat has fallen since the last survey of this age-group in 1986–7 and is close to the dietary reference value, while the proportion of energy derived from saturated fatty acids and non-milk extrinsic sugars exceeds the dietary reference values. The prevalence of overweight and obesity has increased since 1986–7 and physical activity levels are low. [ABSTRACT FROM PUBLISHER]

Plasma total homocysteine (tHcy), cysteine and cysteinyl-glycine were measured in a representative sample of 922 young people aged 4???18 years, participating in the National Diet and Nutrition Survey in mainland Britain in 1997. Both tHcy and cysteine increased markedly with age; cysteinyl-glycine less so. Neither tHcy nor cysteine differed between genders; cysteinyl-glycine was higher in males. tHcy concentrations were lowest in the winter; cysteine and cysteinyl-glycine varied only slightly with season. In respondents aged >15 years, tHcy was higher in smokers, but in respondents aged 7???11 years, tHcy was higher in those whose mothers smoked. tHcy was inversely correlated with serum folate, serum vitamin B12 and vitamin B6 status, but neither cysteine nor cysteinyl-glycine shared these relationships. The relationships between tHcy and B-vitamin status indices ran parallel with those of the 65 years and over survey, but at much lower tHcy concentrations for any given B-vitamin concentration. Age-adjusted tHcy was not correlated with anthropometric indices, blood pressure, haematology, plasma creatinine, urea or cholesterol, but was directly correlated with fasting triacylglycerol. We conclude that disease-risk indices, like tHcy and perhaps cysteine, if established during early life, may be modulated by diet and lifestyle, thereby providing an opportunity for public health intervention.

Objective: To identify eating occasion-level and individual-level factors associated with the consumption of larger portions in young children and estimate their relative importance., Design: Cross-sectional., Setting: Data from parent-reported 4-d food diaries in the UK National Diet and Nutrition Survey (2008-2017) were analysed. Multilevel models explored variation in eating occasion size (kJ) within (n 48 419 occasions) and between children (n 1962) for all eating occasions. Eating contexts: location, eating companion, watching TV, and sitting at a table and individual characteristics: age, gender, ethnicity and parental socio-economic status were explored as potential correlates of eating occasion size., Participants: Children aged 1·5-5 years., Results: Median eating occasion size was 657 kJ (IQR 356, 1117). Eating occasion size variation was primarily attributed (90 %) to differences between eating occasions. Most (73 %) eating occasions were consumed at home. In adjusted models, eating occasions in eateries were 377 kJ larger than at home. Eating occasions sitting at a table, v. not, were 197 kJ larger. Eating in childcare, with additional family members and friends, and whilst watching TV were other eating contexts associated with slightly larger eating occasion sizes., Conclusions: Eating contexts that vary from one eating occasion to another are more important than demographic characteristics that vary between children in explaining variation in consumed portion sizes in young children. Strategies to promote consumption of age-appropriate portion sizes in young children should be developed, especially in the home environment, in eating contexts such as sitting at the table, eating with others and watching TV.

The aims of the National Diet and Nutrition Survey series are summarized, and the new National Diet and Nutrition Survey of people aged 65 years and over is explored, with particular emphasis on micronutrient intakes and status indices. Mean nutrient intakes were generally satisfactory for most micronutrients, but intakes of vitamin D, Mg, K and Cu were low. Intakes of vitamin D were far below the reference nutrient intake for people aged 65 years and over, and there was also biochemical evidence of vitamin D deficiency, for 8 % of free-living and 37 % of institution participants, attributed partly to limited exposure to sunlight. A substantial proportion of people living in institutions had inadequate biochemical status indices, notably for vitamin C, Fe and folate. Relationships between intake and status were close for vitamins. Mineral intakes did not correlate well with currently used status indices. Some intakes and indices, especially those of vitamin C, carotenoids, Na and K, were strongly correlated with socio-economic status and with north???south gradients in Britain. Future research challenges should address the functional and health significance of low intakes and sub-optimal biochemical indices for certain micronutrients, especially for people living in institutions; the shortcomings of mineral status indices especially as indicators of mineral intake; the social and geographical inequalities of micronutrient intakes and status, and why micronutrient status deteriorates with increasing age. The answers to these questions will help to define the characteristics of nutritional risk for older people in Britain, and to clarify future needs for education and intervention.
