RESUMO
BACKGROUND: Diversity is a key component of diet quality and health, but no indicator exists for adolescents under the age of 15 y. OBJECTIVES: To establish a dichotomous indicator for population-level assessment of adolescent dietary diversity as a proxy for micronutrient adequacy. METHODS: We used the probability approach to construct mean probability of adequacy (MPA) of 11 micronutrients from 2 d of 24-h dietary recall data from NHANES, 2007-2018. For each micronutrient, probability of adequacy (PA) was calculated using the best linear unbiased predictor of usual intake. Adolescent dietary diversity score (ADDS) was derived with a maximum score of 10 food groups. Generalized linear mixed models were used to examine associations between ADDS and MPA. Receiver operating characteristic analysis was used to establish a cutoff for minimum dietary diversity for adolescents (MDD-A) using an energy-adjusted logistic model with ADDS predicting MPA > 0.6. RESULTS: PA was >80% for all nutrients except vitamin C (42.1%), folate (65.7%), and calcium (23.8%). Population MPA was 79.4%, and nearly 92% of adolescents had an MPA > 0.6. ADDS was positively associated with MPA, and energy was a significant confounder. The area under the curve was >0.8 on both days with sensitivity and specificity ranging from 0.71 to 0.80. The MDD-A cutoff was calculated as 5.12 and 5.10 food groups on days 1 and 2, respectively. CONCLUSIONS: In U.S. adolescents, the best cutoff for a dichotomous indicator of dietary diversity as a proxy for micronutrient adequacy is 6 food groups in a given day. Future research could validate MDD-A and its associated cutoff for use across country contexts.
RESUMO
Analysing customer loyalty card data is a novel method for assessing nutritional quality and changes in a population's food consumption. However, prior to its use, the thousands of grocery products available in stores must be reclassified from the retailer's original hierarchical structure into a structure that is suitable for the use of nutrition and health research. We created LoCard Food Classification (LCFC) and examined how it reflects the nutritional quality of the grocery product groups. Nutritional quality was considered the main criterion guiding the reclassification of the 3574 grocery product groups. Information on the main ingredient of the product group, purpose of use and carbon footprint was also used at the more granular levels of LCFC. The main challenge in the reclassification was a lack of detailed information on the type of products included in each group, and some of the groups included products that have opposite health effects. The final LCFC has four hierarchical levels, and it is openly available online. After reclassification, the product groups were linked with the Finnish food composition database, and the nutrient profile was assessed by calculating the Nutrient-Rich Food Index (NRFI) for each product group. sd in NRFI decreased from 0·21 of the least granular level to 0·08 of the most granular level of LCFC indicating that the most granular level of LCFC has more homogeneous nutritional quality. Studies that apply LCFC to examine loyalty card data with health and environmental outcomes are needed to further demonstrate its validity.
RESUMO
BACKGROUND AND OBJECTIVES: Frailty has become a public health challenge in China. To investigate the association of foods consumption and physical activity with prefrailty and frailty among older Chinese adults in urban communities. METHODS AND STUDY DESIGN: In a cross-sectional study from February to July 2023, 1183 older adults aged between 65y-88y were enrolled from urban communities in Chongqing and Shandong province, China. Frailty Index (FI) was applied to measure prefrailty and frailty. Partial proportional odds model was used to assess the association between foods consumption, physical activity and prefrailty/frailty. RESULTS: Higher Dietary Diversity Score (DDS), (OR=0.61, 95% CI=0.46-0.80; OR=0.47, 95% CI=0.28-0.79), Consuming animal-based foods ≥2 times/day (OR=0.62, 95% CI=0.47-0.82; OR=0.54, 95% CI=0.33-0.88), soy products ≥2 times/week (OR=0.69, 95% CI=0.53-0.89; OR=0.51, 95% CI=0.31-0.84), fresh vegetables ≥2 times/day (OR=0.42, 95% CI=0.31-0.57; OR=0.41, 95% CI=0.23-0.72), and nuts ≥2 times/week (OR=0.71, 95% CI=0.55-0.91; OR=0.52, 95% CI=0.32-0.85) was associated with a lower risk of prefrailty and frailty. In addition, higher frequency and longer duration of walking (OR=0.61, 95% CI=0.42-0.88; OR=0.63, 95% CI=0.48-0.81), exercise (OR=0.48, 95% CI=0.35-0.64; OR=0.44, 95% CI=0.32-0.61) per week were significantly associated with lower risk of prefrailty. Furthermore, higher frequency and longer duration of walking (OR=0.42, 95% CI=0.25-0.72; OR=0.46, 95% CI=0.29-0.74), and housework (OR=0.39, 95% CI=0.24-0.65; OR=0.57, 95% CI=0.34-0.96) per week, were significantly associated with lower frailty. CONCLUSIONS: Higher DDS and higher frequency of animal-based foods, soy products, fresh vegetables, and nuts consumption is significantly associated with lower risk of prefrailty and frailty. Additionally, walking and exercising are significantly associated with lower risk of prefrailty, while walking and doing housework is significantly associated with lower frailty.

ObjectivesãThe relationship between household income and dietary intake among older children and adults in Japan has been studied. However, few studies have examined the relationship in younger children, and we believe that this should be taken into consideration from early childhood to correct health disparities. In this study, we examined the relationship between family income and dietary food group intake, and investigated the adequacy of food intake based on the Japanese Food Guide Spinning Top for young children aged 3 to 6 years attending nursery school. The goal of this study was to obtain trends in food intake that can be used to improve poor dietary intake of young children caused by socioeconomic factors.MethodsãA dietary survey using the food weighing or recording method and a self-administered questionnaire on dietary status were conducted on two non-consecutive days, including weekdays and weekends, from October to December 2019 or 2020. The participants were 761 young children (423 boys and 338 girls) attending nursery schools in seven cities in Japan. Equivalent income was calculated from household income and the number of family members indicated in the dietary status survey. Intake of each food group and consistency with the Japanese Food Guide Spinning Top were compared in five quintiles.ResultsãCompared to the low equivalent income group, the high equivalent income group showed a decreasing trend in cereal intake and an increasing trend in the intake of sugar and sweeteners, green and yellow vegetables, and dairy products. The percentage of the low-income group who did not meet the definition of adequate intake using the Japanese Food Guide Spinning Top was lower for meals that include cereals and grain products, and higher for meals that include meat and fish, vegetable, milk and dairy products, and fruits.ConclusionãThe lower income group had higher intake of cereals and lower intake of vegetables and fruits compared to the higher income group. This finding is similar to the results of studies in adults and older children. However, based on the Japanese Food Guide Spinning Top, >90% of young children have a diet that fall below the adequate intake of meals, including vegetable dishes and even on weekdays, which suggests a general vegetable deficiency in young children. Multifaceted support is required to address this concern, including measures to correct disparities of income and to ensure desirable nutrient intake in early childhood.

BACKGROUND: The Children's Healthy Living study provided dietary intake information for understudied Native Hawaiian and Other Pacific Islander (NHOPI) young children. OBJECTIVES: Our objective was to describe food group and macronutrient intakes of NHOPI children in the US-Affiliated Pacific region (USAP), overall and by jurisdiction, income level, and metabolic status. METHODS: We evaluated 2-8-y-olds (n = 3520) in a cross-sectional cluster sampled study using 2 d of dietary records completed by caregivers using provided tools, quantified by a specially developed food composition table and compared with US dietary recommendations. Overweight and obesity (OWOB) and acanthosis nigricans (AN) assessment (metabolic status) was completed by trained evaluators using standard tools. Demographic data were collected by questionnaire. Regression analysis identified differences in dietary component means by jurisdiction, World Bank income groups (WBIGs), and metabolic status, adjusted for age and sex. RESULTS: Few children met US recommendations for vegetable (2.4%) and milk (4.1%) food groups. US macronutrient recommendations were generally met. Food group and macronutrient intakes were significantly different by jurisdiction and WBIG. Means for food groups, except meats, and macronutrients, except protein, were higher in overweight/obese (OWOB) compared with healthy-weight children. Grain intake of 7.25 (SE: 0.08) oz was higher (P < 0.05) and milk intake of 0.90 (SE: 0.05) cups was lower (P < 0.05) in children with OWOB compared with those without OWOB [grains: 7.17 (SE: 0.07) oz; and milk: 0.96 (SE: 0.04) cups]. Monounsaturated fat intake of 11.68 (SE: 0.10) % energy was higher in those with OWOB, compared with healthy-weight children [11.56 (SE: 0.08) % energy, P < 0.05]. CONCLUSIONS: Young children's diets in the USAP did not meet milk, vegetable, or fruit intake recommendations. There was variability in dietary patterns across the USAP and by WBIG. Grain intake and monounsaturated fat intake were lower and milk intake was higher in children with better metabolic status.

BACKGROUND: The Diet Quality Questionnaire (DQQ) is a rapid dietary assessment tool designed to enable feasible measuring and monitoring of diet quality at population level in the general public. OBJECTIVES: To evaluate validity of the DQQ for collecting population-level food group consumption data required for calculating diet quality indicators by comparing them with a multipass 24-h dietary recall (24hR) as the reference. METHODS: Cross-sectional data were collected among female participants aged 15-49 y in Ethiopia (n = 488), 18-49 y in Vietnam (n = 200), and 19-69 y in Solomon Islands (n = 65) to compare DQQ and 24hR data in proportional differences in food group consumption prevalence, percentage of participants achieving Minimum Dietary Diversity for Women (MDD-W), percent agreement, percentage misreporting food group consumption, and diet quality scores of Food Group Diversity Score (FGDS), noncommunicable disease (NCD)-Protect, NCD-Risk, and the Global Dietary Recommendation (GDR) score using a nonparametric analysis. RESULTS: The mean (standard deviation) percentage point difference between DQQ and 24hR in population prevalence of food group consumption was 0.6 (0.7), 2.4 (2.0), and 2.5 (2.7) in Ethiopia, Vietnam, and Solomon Islands, respectively. Percent agreement of food group consumption data ranged from 88.6% (10.1) in Solomon Islands to 96.3% (4.9) in Ethiopia. There was no significant difference between DQQ and 24hR in population prevalence of achieving MDD-W except for Ethiopia (DQQ 6.1 percentage points higher, P < 0.01). Median (25th-75th percentiles) scores of FGDS, NCD-Protect, NCD-Risk, and GDR score were comparable between the tools. CONCLUSIONS: The DQQ is a suitable tool for collecting population-level food group consumption data for estimating diet quality with food group-based indicators such as the MDD-W, FGDS, NCD-Protect, NCD-Risk, and GDR score.

PURPOSE: Examining epigenetic patterns is a crucial step in identifying molecular changes of disease pathophysiology, with DNA methylation as the most accessible epigenetic measure. Diet is suggested to affect metabolism and health via epigenetic modifications. Thus, our aim was to explore the association between food consumption and DNA methylation. METHODS: Epigenome-wide association studies were conducted in three cohorts: KORA FF4, TwinsUK, and Leiden Longevity Study, and 37 dietary exposures were evaluated. Food group definition was harmonized across the three cohorts. DNA methylation was measured using Infinium MethylationEPIC BeadChip in KORA and Infinium HumanMethylation450 BeadChip in the Leiden study and the TwinsUK study. Overall, data from 2293 middle-aged men and women were included. A fixed-effects meta-analysis pooled study-specific estimates. The significance threshold was set at 0.05 for false-discovery rate-adjusted p values per food group. RESULTS: We identified significant associations between the methylation level of CpG sites and the consumption of onions and garlic (2), nuts and seeds (18), milk (1), cream (11), plant oils (4), butter (13), and alcoholic beverages (27). The signals targeted genes of metabolic health relevance, for example, GLI1, RPTOR, and DIO1, among others. CONCLUSION: This EWAS is unique with its focus on food groups that are part of a Western diet. Significant findings were mostly related to food groups with a high-fat content.

BACKGROUND: Evidence associating diet with the incidence of renal cell carcinoma (RCC) is inconclusive. We aimed to summarize evidence associating dietary factors with RCC incidence and assess the strength and validity of this evidence. METHODS: We conducted an umbrella review of systematic reviews or meta-analyses (SRoMAs) that assessed the association between diet and RCC incidence. Through April 2021, PubMed, Web of Science, Embase, The Cochrane Library, Scopus, and WCRF were searched. Two independent reviewers selected studies, extracted data, and appraised the quality of SRoMAs. According to credibility assessment criteria, evidence can be divided into five categories: convincing (class I), highly suggestive (class II), suggestive (class III), weak (class IV), and nonsignificant (class V). RESULTS: Twenty-nine meta-analyses were obtained after screening. After excluding 7 overlapping meta-analyses, 22 meta-analyses including 502 individual studies and 64 summary hazard ratios for RCC incidence were included: dietary patterns or dietary quality indices (n = 6), foods (n = 13), beverages (n = 4), alcohol (n = 7), macronutrients (n =15), and micronutrients (n =19). No meta-analyses had high methodological quality. Five meta-analyses exhibited small study effects; one meta-analysis showed evidence of excess significance bias. No dietary factors showed convincing or highly suggestive evidence of association with RCC in the overall analysis. Two protective factors had suggestive evidence (vegetables (0.74, 95% confidence interval 0.63 to 0.86) and vitamin C (0.77, 0.66 to 0.90)) in overall analysis. One protective factor had convincing evidence (moderate drinking (0.77, 0.70 to 0.84)) in Europe and North America and one protective factor had highly suggestive evidence (cruciferous vegetables (0.78, 0.70 to 0.86)) in North America. CONCLUSIONS: Although many meta-analyses have assessed associations between dietary factors and RCC, no high-quality evidence exists (classes I and II) in the overall analysis. Increased intake of vegetables and vitamin C is negatively associated with RCC risk. Moderate drinking might be beneficial for Europeans and North Americans, and cruciferous vegetables might be beneficial to North Americans, but the results should be interpreted with caution. More researches are needed in the future. TRIAL REGISTRATION: PROSPERO CRD42021246619.

BACKGROUND: Resilience, the ability to bounce back or recover from stress, has been associated with several health-related behaviors. However, data on food intake and emotional eating are lacking. OBJECTIVES: The objective of this cross-sectional study was to analyze the associations between resilience and diet quality and ultraprocessed food (UPF) and food group consumption, and to assess whether emotional eating was a mediator of these associations. METHODS: In 2017, 17,840 participants (73.5% female, mean age = 55.4 ± 14.0 y) of the NutriNet-Santé study completed the Brief Resilience Scale, the revised 21-item Three-Factor Eating Questionnaire, and ≥3 self-administered 24-h dietary records. Diet quality was assessed with the modified French National Nutrition and Health Program Guideline Score. Foods and beverages consumed were categorized according to their degree of processing by the NOVA classification. We assessed the association between resilience and emotional eating using linear regression models. We also assessed the mediating role of emotional eating in the associations between resilience and diet quality, energy intake, and UPF and food group consumption, controlling for sociodemographic characteristics. RESULTS: In our study, resilience was negatively associated with emotional eating (P < 0.0001). More resilient participants had greater overall diet quality, greater intakes of seafood, whole-grain foods, fats, unsalted oleaginous fruits, and alcoholic beverages, and lower intakes of UPFs, starchy foods, dairy desserts, sugary fatty products, and sugar and confectionery (all P < 0.05). Emotional eating was a mediator of the inverse associations between resilience and intake of energy, UPFs, dairy desserts, sugary fatty products, and of the positive associations between resilience and alcoholic beverages (all P < 0.05), with a 20-70% mediation. CONCLUSIONS: Our findings showed that resilience was associated with an overall better diet quality in the NutriNet-Santé population-based study. These associations were partially explained by emotional eating. These findings suggest that resilience should be considered in the promotion of healthy dietary habits.The study is registered at clinicaltrials.gov as #NCT03335644.

This study aimed to determine the level of evidence on the association between food groups/items consumption and the risk of different cancer sites from the meta-analyses/pooled analyses of observational studies. A systematic search was executed in Scopus, PubMed/MEDLINE, and Web of Science. The criteria from the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) Expert Report were adopted for evidence grading. In summary, there was convincing evidence for the association between fibre intake and decreased risk of colon and breast cancer. Also, consumption of dairy products, milk, fruits, and fibre was associated with a probable decreased risk of breast cancer. Consumption of whole grains, dairy products, milk, fruits, vegetables, and fibre had a probable inverse association with the incidence risk of gastrointestinal tract cancers. More qualified studies are needed to find reliable findings on the association between various food groups/items consumption and the risk of different cancer sites.

OBJECTIVE: To examine minimum dietary diversity (MDD) trends and determinants among children aged 6-23 months. DESIGN: Secondary analysis of the Indonesia Demographic and Health Surveys (IDHS) between 2007 and 2017. The primary outcome was MDD, the consumption of at least five out of eight food groups (MDD-8). We included a total of 5015 (IDHS 2007), 5050 (IDHS 2007) and 4925 (IDHS 2017) children aged 6 to 23 months to estimate trends of MDD-8 and to identify factors associated with MDD-8. We used multiple logistic regression analysis adjusted for the complex sampling design to investigate the association between the study factors and MDD-8. SETTING: Indonesia. PARTICIPANT: A total of 14 990 children aged 6-23 months. RESULTS: Over the 10 years, the percentage of children who consumed a diversified diet was 53·1 % in 2007, 51·7 % in 2012 and 53·7 % in 2017. Multivariate analyses showed that older age children, higher maternal education, maternal weekly access to media, paternal non-agricultural occupation, history of at least four antenatal care visits and wealthier households were associated with the increased odds of MDD-8. Children living in rural areas, Sulawesi and Eastern Indonesia, were less likely to eat a diversified diet. CONCLUSIONS: The proportion of children meeting MDD-8 has stagnated in the last decade. Child, parental, health care, household and community factors are associated with MDD-8. Therefore, nutrition education programmes and behaviour change communication activities should target mothers and families from socio-economically and geographically disadvantaged populations.
RESUMO
BACKGROUND: The present study aimed to assess micronutrient intake among Greek adults and to identify the main food sources that contribute to it. METHODS: Food consumption data from 2389 participants in the Hellenic National Nutrition and Health Survey (HNNHS), collected with 24-h recalls, was used to calculate micronutrient intakes. Usual nutrient intake was estimated according to the National Cancer Institute method. Nutrient adequacy was estimated using the estimated average requirement (EAR) cut-point method, when available, or adequate intake otherwise. The probability approach was used to determine iron intake adequacy in females of reproductive age. Food group contribution for each nutrient assessed was derived to identify their main food sources. RESULTS: Almost all individuals had vitamin D intake below EAR, whereas vitamins A, E, K and C, as well as potassium intake, were also insufficient in a considerable percentage of the population (>70% in most age groups). Calcium intake was substantially below the EAR for females aged >50 years and males >70 years; the same for magnesium in males >70 years. Furthermore, 50% of females, including those of reproductive age, had intake of folate below EAR. More than 50% of the population (to 79%) exceeded the upper tolerable limit for sodium (2300 mg day-1 ). Food contribution analysis revealed that most vitamins were derived from low-quality foods (i.e. fast-food). CONCLUSIONS: A significant proportion of adults residing in Greece have low nutrient intake and poor food selections. These results provide guidance to public health policy makers for developing strategies to improve the dietary quality in Greece.

BACKGROUND: Consumption of food groups aligning with dietary guidelines is advised for obesity management and was used in a recent lifestyle intervention trial, the Health Track study. We have conducted a number of dietary pattern analyses on this trial but, with recent access to the new Australian Dietary Guidelines (ADG) food composition database, we can now assess ADG adherence, with the advantage of categorising mixed dishes. The present study aimed to compare changes over time in consumption of ADG food groups. METHODS: Secondary analysis of baseline and three-month diet history data was conducted. Participants received individualised dietary advice (I), individualised dietary advice plus 30 g of walnuts per day (IW) or usual care (C). The ADG database was used to determine food group servings with changes in five food groups used as a measure of dietary quality. RESULTS: Fruit and vegetable intakes increased in the IW (+0.4 and +1.1 serves, P < 0.05) and I (+0.5 and +0.4 serves, P > 0.05) arms. Consumption of meat/protein foods increased in the IW arm (+0.3 serves, P > 0.05) but decreased in the I and C arms (both - 0.4 serves, P < 0.05). Consumption of grains and milk/alternatives decreased in all study arms (P < 0.05). Greater improvements in grain and dairy food quality were observed in the intervention arms. CONCLUSIONS: The ADG database enabled ADG specific food group analysis, addressed food quality and showed the HealthTrack intervention increased adherence to dietary guidelines compared to usual care.

BACKGROUND: FFQs are commonly used to assess dietary intake and it is important to evaluate their performance in the target population. OBJECTIVE: We evaluated the reproducibility and relative validity of the Cancer Prevention Study-3 (CPS-3) FFQ in estimating usual intake of 63 food groups and diet quality in accordance with the American Cancer Society dietary guidelines for cancer prevention. METHODS: A subset of participants from the CPS-3 (433 women, 244 men), 31-70 y of age, were included in a cross-sectional diet assessment substudy (2015-2016). Reproducibility was assessed by comparing estimates from repeat FFQs, approximately 1 y apart, using Spearman correlation coefficient (rs) and Pearson correlation coefficient (rp) correlations for food groups and diet quality, respectively. Validity was assessed similarly by comparing FFQ estimates with estimates from ≤6 interviewer-administered 24-h dietary recall (24HR). Analyses were stratified by sex and race/ethnicity. RESULTS: Reproducibility correlations for repeated FFQs were > 0.50 for 83-97% of food groups analyzed across strata of sex and race. Although participants tended to overreport plant foods (e.g., fruits and legumes) and underreport refined grains and sugar-sweetened beverages, the median energy-adjusted, deattenuated Spearman correlations comparing the second FFQ to the 24HR were 0.50 and 0.52 among men and women (range: 0.05-0.82), respectively, suggesting that ranking was preserved for most food groups. Validity was highest for coffee, alcohol, and total dairy, and lowest for pasta and regular-fat yogurt. Median validity across food groups varied by race/ethnicity and was highest among whites (rs = 0.54) followed by Hispanics (rs = 0.49) and African Americans (rs = 0.45). The diet quality score had good validity in all subgroups examined, but was higher among men (rp = 0.69) than women (rp = 0.61), and lower among whites (rp = 0.62) than Hispanics (rp = 0.64) or African Americans (rp = 0.73). CONCLUSIONS: This study indicates good reproducibility and validity of the CPS-3 FFQ for most major food groups and the diet quality score in all sex and race/ethnicity groups examined.

BACKGROUND: In 2009 the USDA's Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) updated the food packages provided to participants. OBJECTIVES: This study investigates associations between WIC participation and nutrients and food groups consumed using data from the Feeding Infants and Toddlers Study's 2008 and 2016 nationwide, cross-sectional surveys of children <4 y, weighted to be representative of the US population. METHODS: The study data included 2892 children aged 6-47.9 mo in 2008 and 2635 in 2016. Differences were analyzed by WIC participation, survey year, and child age (infants 6-11.9 mo old, toddlers 12-23.9 mo old, preschoolers 24-47.9 mo old). Usual nutrient intake distributions were estimated using National Cancer Institute methodology. Daily food group consumption differences were tested via multivariate regression. All analyses controlled for income. RESULTS: In 2016 18.6% of infants had iron intakes below the estimated average requirement (EAR), compared to 7.6% in 2008; 87% of WIC infants met the EAR, compared with 69% of non-WIC infants. In 2016 37% of WIC preschoolers met saturated fat guidelines, compared with 25% in 2008; in both years, fewer than one-third of non-WIC preschoolers met the guidelines. More WIC infants than non-WIC infants consumed infant cereals in 2016 (58% compared with 45%, respectively). More WIC infants ate vegetables daily in 2016 than in 2008 (74% compared with 59%, respectively). In 2016, as compared with 2008, more WIC infants consumed baby-food vegetables (55% compared with 29%, respectively) and fruits (56% compared with 41%, respectively). In 2016 47% of WIC preschoolers drank low-fat milk, compared with 19% of non-WIC preschoolers. CONCLUSIONS: Infant iron intakes are concerning, although more WIC infants meet the EAR. WIC infants' vegetable intakes have improved; baby-food vegetables have become important contributors to their intakes. In 2016 WIC children were more likely than non-WIC children to shift to lower-fat milks at 2 y of age, likely contributing to lower saturated fat intakes.

Objective: Although brain atrophy is a natural process of healthy aging, diet may play a role in delaying the process across age. We sought to investigate how food groups associate brain region-specific volume changes over 4 years in a general population. Methods: We obtained data from the Korean Genome and Epidemiology Study on 848 community-dwelling individuals. The participants completed a dietary examination using a food frequency questionnaire between 2005 and 2006 to determine habitual usual intakes of food consumption and two brain magnetic resonance imaging (MRI) scans between 2011 and 2014 and between 2015 and 2017, respectively. The 106 food items in the questionnaire were regrouped into 18 food groups. A multivariable generalized linear model was used with the adjustment of potential confounding variables. Results: The average age at baseline was 53.5 years. The average follow-up year of brain MRI was 4.13 ± 0.33 years. With considering a corrected p value due to multiple comparisons, vegetable intake indicated a statistically significant inverse association with gray matter volume change (ß = -2.28, p = 0.006), after adjusting for potential confounding variables. Particularly, the temporal region showed a significant inverse association with vegetable intake (ß= -0.63, p = 0.002). Conclusions: In a longitudinal study among 848 cognitively healthy participants from a general population, we found significant inverse associations between vegetable intake and brain gray matter volume change, particularly the change of temporal region.

PURPOSE: To examine the associations of energy, macronutrient and food intakes with GWG on 960 pregnant women from the Growing Up in Singapore Towards healthy Outcomes (GUSTO) mother-offspring cohort. METHODS: Dietary intake was assessed at 26-28 weeks' gestation with a 24-hour recall and 3-day food diary. GWG z-scores were calculated from first (4-13 weeks' gestation) and last (30-40 weeks gestation) measured weights; inadequate and excessive GWG were defined using the Institute of Medicine recommendations based on weights between 15 and 35 weeks' gestation. Associations were examined using substitution models for macronutrient composition, with linear or multinomial logistic regressions. RESULTS: Mean ± SD daily energy intake was 1868 ± 598 kcal, and percentage energy intakes were 51.8 ± 8.9% from carbohydrate, 15.7 ± 3.9% from protein and 32.6 ± 7.7% from fat. Higher energy intake (per 500 kcal increment) was associated with 0.18 SD higher GWG. In isocaloric diets, higher-carbohydrate and lower-fat intakes (at 5% energy substitution) were associated with 0.07 SD higher GWG, and 14% higher likelihood of excessive GWG. Concordantly, the highest tertile of carbohydrate-rich foods intake was associated with 0.20 SD higher GWG, but the highest tertile of fruit and vegetable intake was independently associated with 60% lower likelihood of inadequate GWG. Additionally, the highest tertile of dairy intake was associated with 0.18 SD lower GWG; and the highest tertile of plant-based protein foods intake was associated with 60% and 34% lower likelihood of inadequate and excessive GWG. CONCLUSIONS: Balancing the proportions of carbohydrates and fat, and a higher intake of plant-based protein foods may be beneficial for achieving optimal GWG.

OBJECTIVE: To develop a dish composition database (DCD) and assess its ability to estimate dietary intake. DESIGN: The DCD was developed based on 16 d dietary records (DR). We aggregated all reported dishes into 128 dish codes and calculated mean food group and nutrient contents for each code. These data were used to calculate dietary intake in a different population that completed a 4 d DR. The estimated values were compared with those estimated using the standard food composition database (FCD) of Japan. SETTING: Japan. PARTICIPANTS: A total 252 adults aged 31-81 years for the 16 d DR (3941 d in total) and 392 adults aged 20-69 years for the 4 d DR (1568 d in total) participated. RESULTS: There were significant differences in median intakes between the DCD and the FCD for eighteen and twenty (of twenty-six) food groups and for twenty-nine and twenty-two (of forty-three) nutrients (including energy) in men and women, respectively. For food group intakes, Spearman correlation coefficients between the DCD and FCD ranged from 0·19 (animal fats) to 0·90 (fruits and alcoholic beverages) in men (median: 0·61) and from 0·25 (oils) to 0·89 (noodles) in women (median: 0·58). For nutrient intakes, the corresponding values ranged from 0·25 (retinol) to 0·90 (alcohol) in men (median: 0·60) and from 0·15 (retinol) to 0·74 (alcohol) in women (median: 0·53). CONCLUSIONS: Whereas it is difficult to accurately estimate absolute dietary intake values using the present DCD, it has acceptable ability to rank the intakes of many food groups and nutrients.

Context: The average Japanese lifespan became the longest in the world in 1986. What factors give the Japanese this longevity? Washoku, or the traditional Japanese diet, is respected globally for its nutritionally-balanced and healthy eating habits. This uniquely Japanese way of eating may be one factor that helps extend the Japanese lifespan. Objective: To explain the nutrition intake characteristics of today's Japanese elderly compared with their children's generation and to discuss the association between nutrition intake and various diseases and health issues in the general adult population. Methods: This study compared the characteristics of nutrition status and nutrition intake among today's elderly and their children's generation by using National Health and Nutrition Survey scores. Results: Japanese elderly had high adequacy in all nutrients as well as a high intake of potatoes, pulses, vegetables, fruits, algae, and fish and shellfish compared with their children's generation. Conclusion: Nutrition intake among the Japanese elderly had the characteristics of washoku, but these characteristics were not passed on to the next generation. Extension of the average lifespan and improved health could be achieved by modifying nutrition intake, even after reaching the age of onset of lifestyle- and age-related diseases, typically the 50s.

ISSUE ADDRESSED: Evidence indicates adolescents do not comply with the Australian Guide to Healthy Eating (AGHE)-recommended daily serves (RDS). Little research has identified their level of knowledge regarding the guidelines and associations with food intake. METHODS: Survey methodology was used to measure knowledge of the Healthy Living Pyramid (HLP) and the AGHE-RDS. Food group intake was measured using a modified food frequency questionnaire. A generalised linear model (GLM) investigated the associations between the HLP, RDS knowledge and daily equivalent frequencies (DEFs) for each food group. RESULTS: The study comprised 190 students aged 14-15 years. The majority reported accurate knowledge of the HLP. Only fruit and vegetable RDS was correctly identified. Participants did not meet DEFs for any food group. For both DEF grains (P = 0.004) and vegetables (P = 0.023) participants with correct knowledge reported a DEF closer to the RDS. For DEF-baked goods and snacks (P = 0.012), participants reporting correct knowledge also reported DEF closer to the RDS. No associations were identified for the other food groups. SO WHAT?: Knowledge of the HLP was more accurate than the AGHE-RDS. Knowledge of fruit and vegetable RDS was better than the other food groups. The positive associations between knowledge and compliance with the RDS suggest knowledge can influence food choice. However, the lack of associations between knowledge and consumption for most food groups suggests clear "do" messages, similar to Go for 2&5, about the RDS for all food groups should be developed for adolescents.
