Fortified Foods Are Major Contributors to Nutrient Intakes in Diets of US Children and Adolescents

BackgroundEven in an era of obesity and dietary excess, numerous shortfall micronutrients have been identified in the diets of US children and adolescents. To help tailor strategies for meeting recommendations, it is important to know what foods contribute greatly to micronutrient intakes. Data are lacking on specific contributions made by added nutrients.ObjectiveOur aims were to examine the impact of fortification on nutrient adequacy and excess among US children and adolescents and to rank food sources of added nutrient intake and compare rankings with those based on total nutrient intake from foods.Design and statistical analysesData were from 7,250 respondents 2 to 18 years old in the National Health and Nutrition Examination Survey 2003-2006. Datasets were developed that distinguished nutrient sources: intrinsic nutrients in foods; added nutrients in foods; foods (intrinsic plus added nutrients); and total diet (foods plus supplements). The National Cancer Institute method was used to determine usual intakes of micronutrients by source. The impact of fortification on the percentages of children having intakes less than the Estimated Average Requirement and more than the Upper Tolerable Intake Level was assessed by comparing intakes from intrinsic nutrients to intakes from intrinsic plus added nutrients. Specific food sources of micronutrients were determined as sample-weighted mean intakes of total and added nutrients contributed from 56 food groupings. The percentage of intake from each grouping was determined separately for total and added nutrients.ResultsWithout added nutrients, a high percentage of all children/adolescents had inadequate intakes of numerous micronutrients, with the greatest inadequacy among older girls. Fortification reduced the percentage less than the Estimated Average Requirement for many, although not all, micronutrients without resulting in excessive intakes. Data demonstrated the powerful influence of fortification on food-source rankings.ConclusionsKnowledge about nutrient intakes and sources can help put dietary advice into a practical context. Continued monitoring of top food sources of nutrients and nutrient contributions from fortification will be important.     

Fat intake in children with autism spectrum disorder in the Mediterranean region (Valencia,Spain)

Objective: Children with autism spectrum disorder (ASD) have been found to have alterations in dietary fat intake and fat quality. The fat intakes of the foods consumed by children with and without ASD were compared, and the deficiency and excess of these nutrients were examined.

Methods: In a matched case–control study, 3-day food diaries were completed by 105 children with ASD and 495 typically developing (TD) 6- to 9-year-old children in Valencia (Spain). We used the probabilistic approach and estimated average requirement cut-point to evaluate the risk of inadequate nutrients intakes. These were compared between groups and with Spanish recommendations using linear and logistic regression, respectively.

Results: Groups did not differ significantly in age, total dietary intake, Healthy Eating Index, or food variety score. Children with ASD had lower saturated fatty acids (SFAs) and ω-3 polyunsaturated fatty acids (PUFAs) intakes, but their total PUFAs and (PUFAs?+?monounsaturated fatty acids (MUFAs)/SFAs, PUFAs/SFAs intakes and ω-6/ω-3 ratios were higher than TD children. The total fat and cholesterol intakes of both groups were slightly above Spanish recommendations. Both groups had low ω-6 intakes, very low ω-3 intakes, and high ω-6/ω-3 ratios.

Conclusion: Further research is required to clarify associations between ASD symptomatology, fat-eating patterns and health status.     

Evaluation of a Quantitative Food Frequency Questionnaire for 5-Year-Old Children in an Asian Population

BackgroundFood frequency questionnaires (FFQs) are often used to assess dietary intakes due to their ability to assess intake over extended periods, their low respondent burden, and their cost-effectiveness. A quantitative FFQ that includes locally appropriate food items for 5-year-old children in a multiethnic Asian population was developed, but its validity has not previously been evaluated.ObjectiveTo evaluate the relative validity of a newly developed FFQ as a dietary assessment tool for 5-year-old children in a multiethnic Asian population.DesignThe 112 –food item FFQ was administered by trained interviewers to caregivers of children. Frequency of food items consumed in the previous month and portion size information were collected. The FFQs were evaluated against 3-day nonweighed diet records (DRs) completed by caregivers.Participants/settingThe dietary data of 361 children aged 5 years from the Growing Up in Singapore Towards Healthy Outcomes mother-offspring cohort were collected in 2015-2016.Main outcome measuresNutrients of interest included energy, macronutrients, fiber, cholesterol, vitamin A, beta carotene, calcium, and iron, calculated from the FFQs and DRs.Statistical analyses performedNutrient intakes according to FFQs in relation to DRs were assessed using Pearson’s correlation, Lin’s concordance, Bland-Altman plots, quintile joint classification, and Cohen’s κ statistics.ResultsThe highest energy-adjusted correlation (Pearson’s r=0.71) and concordance (Lin’s concordance=0.69) were observed for calcium. Fiber, saturated fat, polyunsaturated fatty acids (PUFA), cholesterol, and iron also showed correlation coefficients and concordance of at least 0.40. Bland-Altman plots suggested no substantial bias across ranges of intakes for the nutrients with correlations and concordance of 0.40 or above. Quintiles joint classification showed substantial agreement for calcium (κ=0.66), and moderate agreement for iron, fiber, saturated fat, polyunsaturated fat, and beta carotene (κ=0.59, 0.54, 0.49, 0.44, 0.43, respectively).ConclusionsThe newly developed FFQ is in reasonable agreement with DR for estimating intakes of calcium, fiber, saturated fat, PUFA, cholesterol, and iron. In addition, the FFQ is able to classify children according to quintiles of nutrient intakes, with moderate to substantial quintile agreements between FFQ and DR for calcium, iron, fiber, saturated fat, PUFA, and beta carotene. To assess the remaining nutrients, DR method is recommended instead of the FFQ.     

Food consumption and nutrition of regional tribes of India†

Systematic investigations of food availability, dietary patterns, nutritional levels, were initiated among aboriginal tribes in different regions in India. These studies also compared nutritional intakes to the physiological requirement of the groups as well as the influence of respective dietaries on physique, working efficiency and growth of children. The 31 tribes investigated were located in the North‐Eastern Frontier, Eastern India, the Central region, Southern states and Andaman and Nicobar islands. Samples of food and homely brewed alcoholic beverages collected during the investigation were analysed for nutrient content.

The investigations provided considerable information on living conditions. A comparative study of family size, total food intakes, supplies of food energy, proteins, minerals and vitamins as well as correlations between dietary patterns and growth of children and Korperfulle index of body build revealed that 14 tribes (47 percent) were well fed and in satisfactory nutritional status, eight (23 percent) were underfed and deficient in many nutrients. Nine tribes (30 percent) lived in utmost poverty and were grossly deficient in all the nutrients and were in a state of physical degeneration and nutritional depletion. This may also be the reason for the degeneration, depletion and ultimate extinction of many regional tribes of India.     

Dietary macro- and micronutrient intakes of nonsupplemented pre- and postmenopausal women with a perspective on menopause-associated diseases.

OBJECTIVES: To assess the dietary intakes and diet quality of menopausal women relative to premenopausal women, and to determine whether their diets are compatible with reducing risks of cardiovascular disease (CVD) and osteoporosis. DESIGN: Cross-sectional study using 3-day food records and anthropometric measurements. Subjects Thirty apparently healthy, nonoestrogen using and nonsupplemented women menopausal since 3-5 years and 30 well-matched premenopausal women. Outcome measures Nutrient intakes, diet nutrient density, body mass index (BMI), waist circumference, waist-to-hip ratio and serum oestradiol. RESULTS: Energy intake and body weight of pre- and postmenopausal women were comparable. Their BMI, waist circumference and waist-to-hip ratios were within healthy ranges. The diet of postmenopausal women was compatible (less total lipids and saturated fatty acids; more fibres, antioxidant vitamins and potassium) with North American nutritional recommendations linked to cardiovascular health. Their dietary iron intakes exceeded their reduced physiological need, which may jeopardize their cardiovascular system. Their calcium and vitamin D intakes were far below recommendations for healthy bones. Five other nutrients were also suboptimal. Phosphorus intake (high in both groups) correlated with dietary proteins, sulphur amino acids and calcium. CONCLUSIONS: The diet of the postmenopausal women studied were more compatible with national nutritional recommendations than that of premenopausal controls. However, these postmenopausal women, not taking hormone replacement therapy (HRT) and having inadequate dietary calcium and vitamin D intakes, may be at increased risk of osteoporotic fracture later in life. More studies on CVD risk inherent to body iron accumulation involving a large number of postmenopausal women are warranted before planning public health measures regarding dietary iron intake.     

Disparities in Nutritional Adequacy of Diets between Different Socioeconomic Groups of Finnish Adults

Information on dietary adequacy is needed to assess food and nutrition security in a modern society, especially in the transition towards climate-friendly food systems. In this study, differences in the nutritional adequacy of diets among Finnish adults were evaluated in population groups of different education, income and urbanisation levels. The study used data from the FinDiet 2017 Survey (n = 1655, 18–74 years). Modelled usual intakes of foods and nutrients were evaluated relative to food-based dietary guidelines issued by the National Nutrition Council of Finland (FNNC) and with respect to nutrient adequacy following the Nordic Nutrition Recommendations and FNNC. For about half of the nutrients studied, intakes were found to be adequate. Intakes of protein, fat, saturated fatty acids and salt were estimated to be high. By contrast, inadequate intakes were seen in folate and vitamins A, D, B1, B2 and C in almost all groups studied. Groups with a higher education and income, groups that lived in urban areas and, in particular, women adhered more closely to recommended food consumption and nutrient intakes than others. However, major challenges posed by the Finnish diet are common to all groups studied, and only certain dietary features evaluated in view of nutritional adequacy are associated with socioeconomic differences.     

A probabilistic intake model to estimate the impact of reformulation by the food industry among Irish consumers

Abstract

This project quantified the impact that voluntary reformulation efforts of the food industry had on the Irish population’s nutrient intake. Nutrient composition data on reformulated products were collected from 14 major food companies for two years, 2005 and 2012. Probabilistic intake assessments were performed using the Irish national food consumption surveys as dietary intake data. The nutrient data were weighted by market shares replacing existing food composition data for these products. The reformulation efforts assessed, significantly reduced mean energy intakes by up to 12?kcal/d (adults), 15?kcal/d (teens), 19?kcal/d (children) and 9?kcal/d (pre-schoolers). Mean daily fat intakes were reduced by up to 1.3?g/d, 1.3?g/d, 0.9?g/d and 0.6?g/d, saturated fat intakes by up to 1.7?g/d, 2.3?g/d, 1.8?g/d and 1?g/d, sugar intakes by up to 1?g/d, 2?g/d, 3.5?g/d and 1?g/d and sodium intakes by up to 0.6?g/d, 0.5?g/d, 0.2?g/d, 0.3?g/d for adults, teenagers, children and pre-school children, respectively. This model enables to assess the impact of industry reformulation amongst Irish consumers’ nutrient intakes, using consumption, food composition and market share data.     

Dietary shortcomings in children on a gluten‐free diet

Background: Coeliac disease (CD), or permanent gluten intolerance, is one of the most common chronic food‐related diseases among children in Europe and the USA. The treatment is lifelong gluten‐free diet (GFD) (i.e. the exclusion of wheat, rye and barley from the diet, which are important sources particularly of iron, dietary fibre and vitamin B). The present study aimed to evaluate dietary intakes of energy and nutrients in children and adolescents on GFD and compare these with intake of comparable age groups on a normal diet as well as current recommendations. Methods: Thirty children, 4–17 years of age with confirmed CD and on GFD were agreed to participate in this study at the Department of Pediatrics, Umeå University Hospital. Weight and height were used to calculate individual energy requirement according to Nordic Nutrition Recommendations 2004 (NNR‐04). Dietary intake was assessed using 5‐day food records and household measures were used for quantities. Twenty‐five children completed their dietary record. Results: Thirteen of the 25 children did not meet the recommended energy intake and the dietary intakes were inadequate regarding quality of macronutrients and quantity of minerals and vitamins. The mean intakes of sucrose and saturated fatty acids were above and the intakes of dietary fibre, vitamin D, magnesium and selenium below the NNR‐04. High intakes of sucrose and saturated fat and a low intake of dietary fibre were also noted in a previous national survey on healthy children on a normal diet. The nutrient density of vitamin D, riboflavin, niacin, thiamine, magnesium and selenium were lower among CD children than healthy children but, for iron and calcium, it was higher in CD children. Conclusions: Children on GFD appear to follow the same trends as healthy children on a normal diet, with high intakes of saturated fat and sucrose and low intakes of dietary fibre, vitamin D and magnesium compared to recommendations.     

Contributions of Early Care and Education Programs to Diet Quality in Children Aged 3 to 4 Years in Central North Carolina

BackgroundParents and early care and education (ECE) are the key influencers of young children’s diets, but there is limited information about how each contribute to children’s overall diet quality.ObjectiveThis study aimed to determine what proportion of children’s dietary intake occurs within the ECE setting and whether diet quality is higher at ECE centers and, consequently, on weekdays than weekends.DesignThis cross-sectional analysis of a larger cluster randomized controlled trial used multiple 24-hour dietary intakes measured through a combination of the Dietary Observation in Child Care protocol and parent-reported food diaries.Participants/settingParticipants (N=840) included children aged 3 to 4 years enrolled in ECE centers in central North Carolina for whom 24-hour dietary intake was captured via observation of meals and snacks consumed at ECE and parent-report of all remaining meals and snacks. Data were collected from 2015 to 2016.Main outcome measuresDiet quality at ECE and elsewhere was evaluated using the Healthy Eating Index 2015.Statistical analyses performedMixed-effects models were used to determine differences in mean Healthy Eating Index 2015 component and total scores. Models were adjusted for children’s age and sex and accounted for clustering within ECE centers and families.ResultsChildren consumed approximately 40% of daily energy, nutrients, and food groups at ECE centers. The mean total Healthy Eating Index 2015 score was higher for foods and beverages consumed at ECE centers (58.3±0.6) than elsewhere (52.5±0.6) (P<0.0001). The mean total Healthy Eating Index 2015 score was also higher on weekdays (58.5±0.5) than on weekends (51.3±0.5) (P<0.0001).ConclusionsChildren consume a majority of dietary intake away from ECE centers. Overall, diet quality is low, but the quality of foods consumed by children at ECE centers is higher than that consumed elsewhere. ECE centers remain an important source of nutrition and further investigation is warranted to identify ways to support both ECE centers and families to provide healthier eating environments.     

Dietary Quality and Usual Intake of Underconsumed Nutrients and Related Food Groups Differ by Food Security Status for Rural,Midwestern Food Pantry Clients

BackgroundFood pantry users represent a predominantly food insecure population, yet dietary intake may differ among food secure (FS), low FS, and very low FS clients. Usual intake of food groups and nutrients by food security status has not previously been compared among food pantry clients.ObjectiveThis study aimed to estimate the usual intakes of underconsumed nutrients (ie, potassium; dietary fiber; choline; magnesium; calcium; vitamins A, D, E, and C; and iron) and related food groups (ie, vegetables, fruits, whole grains, and dairy) and dietary quality, and to evaluate their relationship with food security status.DesignThis cross-sectional, secondary analysis used baseline data from a prior intervention study (Clinical Trial Registry: NCT03566095). A demographic questionnaire, the US Household Food Security Survey Module, and up to three 24-hour dietary recalls on nonconsecutive days, including weekdays and weekends, were collected.Participants/settingThis community-based study included a convenience sample of adult, midwestern food pantry clients (N=579) recruited from August to November 2014.Main outcome measuresMain outcomes evaluated were Healthy Eating Index-2010 scores and usual intakes of underconsumed nutrients and related food groups.Statistical analyses performedLinear regression models and the National Cancer Institute method, adjusting for confounders, were used to estimate associations of food security with diet quality and usual intake, respectively.ResultsBeing FS was associated with a higher whole grains HEI-2010 score and higher mean usual intake of whole grains compared with being low FS. Being FS was associated with higher usual intakes of iron and dairy compared with being very low FS. Being FS was associated with a higher mean usual intake of dark green vegetables compared with being low FS and very low FS. Usual intakes were below federal guidance for all subgroups of food security.ConclusionsAlthough food security status may differentiate dietary intake among food pantry clients, improvements are needed among all clients.     

Children's Dietary Intake by Early Care and Education Setting in the US Affiliated Pacific

ObjectiveExamine differences in dietary intake of children aged 2–5 years in early care and education (ECE) setting in the US Affiliated Pacific (USAP).DesignSecondary analysis of cross-sectional data collected by the Children's Healthy Living program.ParticipantsChildren (n = 1,423) with complete dietary records and information on the ECE setting.Main Outcome MeasuresDietary intake by ECE setting; Head Start (HS), other ECE (OE), and no ECE.AnalysisComparison of mean dietary intake across ECE settings and multivariate logistic regression to evaluate ECE setting and likelihood for meeting dietary reference intake (DRI).ResultsChildren in HS and OE settings had a significantly higher intake of several food groups and nutrients, compared with no ECE; vegetables (0.4 cup-equivalents per thousand kcals [CETK] vs 0.3 CETK; P < 0.001), fruits (0.8 CETK vs 0.6 CETK; P = 0.001), milk (0.9 CETK for HS and 1.0 CETK for OE vs 0.8 CETK; P < 0.001). Sixty-five percent of the HS group met DRI and had greater odds of meeting calcium DRI (odds ratio, 1.8; 95% confidence interval, 1.2–2.7) compared with other groups. The OE group had the lowest proportion of children meeting recommended intakes for 19 out of 25 nutrients.Conclusions and ImplicationsMean intakes of foods and nutrients for children across the USAP meet some, but not all, recommendations and intakes vary across children attending various ECE setting types. Additional research on the clinical importance of these differences and the impact of the complex food systems in the USAP may identify systematic strategies for improving diet among children.     

Perceived Access and Actual Intake of Healthy Diets Among Households in Vulnerable Salvadoran Communities

ObjectiveThis study aimed to examine the dietary intake of Salvadoran households according to perceived access to healthy meals (PAHD), and to identify household characteristics associated with diet quality and PAHD.MethodsSecondary data analysis with a sample of 139 Salvadoran households from resource-poor communities in El Salvador. Chi-square tests and ANOVA were used to assess differences in dietary intake across households classified according to PAHD.ResultsHigh-PAHD households had higher women's education, household food security levels, overall diet quality, and variety, and higher intakes of animal products, fats, cholesterol, vitamin C, and sodium (P < .05). Diet quality was not associated with the household characteristics studied.Conclusions and ImplicationsOverall diet quality was associated with higher levels of PAHD, but some differences in intakes were not as expected, such as higher intakes in foods and nutrients associated with low-quality diets, among high PAHD households.     

Breakfast in Latin America: Evaluation of Nutrient and Food Group Intake Toward a Nutrient-Based Recommendation

BackgroundLittle is known about breakfast habits of the Latin American (LA) population to support nutritional recommendations for a balanced breakfast in this region.ObjectiveTo evaluate the nutritional composition of breakfast in the LA population and to propose recommendations for a balanced breakfast.DesignThis multicenter cross-sectional study evaluated food and nutrient intake of nationally representative samples of urban populations of 8 LA countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela) in 2014-2015.Participants/settingThe sample comprised 8714 participants from the Latin American Study of Nutrition and Health, aged 15 to 65 years, randomly recruited according to geographical location, sex, age, and socioeconomic level.Main outcome measuresTwo 24-hour recalls were used to examine dietary intake. Breakfast consumers were stratified by tertiles of Nutrient-Rich Foods Index 9.3 (NRF9.3) to assess the overall diet quality of individuals. Nutrient intake at breakfast of those in the upper tertile of NRF9.3 pooled for the 8 countries was used as a reference for the development of recommendations for LA adolescents and adults.Statistical analysesComparison of food and nutrient intake of breakfast across NRF9.3 tertiles were analyzed using the Kruskal-Wallis rank sum test.ResultsOverall breakfast was an important contributor to protein, carbohydrate, and B vitamin intakes but also to added sugar and total and saturated fat intakes relative to daily intakes. Individuals in the upper NRF9.3 tertile had higher intake of key micronutrients such as calcium and potassium at breakfast compared with other tertiles. White breads/rolls/tortillas were the most consumed food group (60%), followed by butter/margarine (40%) and coffee/tea without milk (34%-50%).ConclusionsBreakfast contributed to the daily intake of B vitamins, protein, and carbohydrates but also added sugar and total and saturated fat intakes for all countries. The proposed recommendations support the nutrient density of existing highest-quality breakfast in the LA population while addressing concerns about nutrients to be encouraged or reduced.

Gluten-free diet survey: are Americans with coeliac disease consuming recommended amounts of fibre,iron, calcium and grain foods?

OBJECTIVE: This survey was conducted to assess nutrient intakes and food consumption patterns of adults with coeliac disease who adhere to a strict gluten-free diet. DESIGN: Three-day estimated self-reported food records were used to assess daily intakes of calories, percent daily calories from carbohydrates, dietary fibre, iron, calcium and grain food servings. SUBJECTS: Volunteers for this survey were recruited through notices placed in coeliac disease support group newsletters, as well as a national magazine for persons with coeliac disease. Forty-seven volunteers met all criteria for participation and returned useable food records. RESULTS: Group mean daily intake of nutrients by gender: Males (n = 8): 2882 calories; 55% carbohydrate; 24.3 g dietary fibre; 14.7 mg iron; 1288.8 mg calcium; 6.6 grain food servings. Females (n = 39): 1900 calories; 52% carbohydrate; 20.2 g dietary fibre; 11.0 mg iron; 884.7 mg calcium; 4.6 grain food servings. Recommended amounts of fibre, iron and calcium were consumed by 46, 44 and 31% of women and 88, 100 and 63% of men, respectively. CONCLUSIONS: Nutrition therapy for coeliac disease has centred around food allowed/not allowed on a gluten-free diet. Emphasis also should be placed on the nutritional quality of the gluten-free diet, particularly as it concerns the iron, calcium and fibre consumption of women. The use of the estimated food record as the dietary survey method may have resulted in the under-reporting of energy intake. Due to the small sample size and possible bias of survey participants, the findings of this survey may not be representative of the larger coeliac community.     

Dietary intake and major food sources of polyphenols in Finnish adults

Phenolic acids, flavonoids, proanthocyanidins, and ellagitannins are polyphenols that may have beneficial effects on human health and provide protection against chronic diseases. To date, limited data exist on quantitative intake of polyphenols. The aims of this study were to estimate the quantitative intakes of polyphenols by using analyzed concentrations together with individual food consumption records and to determine major dietary sources. Analyzed concentrations of phenolic acids, anthocyanidins, and other flavonoids, proanthocyanidins, and ellagitannins (44 total polyphenol compounds) were entered into the national food composition database, Fineli. The absolute intakes of the polyphenols and the corresponding food sources were calculated on the basis of 48-h dietary recalls of 2007 Finnish adults. The mean total intake of polyphenols was 863 +/- 415 mg/d. Phenolic acids comprised the dominant group of polyphenols (75% of total intake) followed by proanthocyanidins (14%) and anthocyanidins and other flavonoids (10%). Due to their high consumption and high concentrations of phenolic acids, coffee and cereals were the main contributors to total polyphenol intake. Berries and berry products were the main source for anthocyanidins, ellagitannins, and proanthocyanidins, and fruits were the main source for flavonols, flavones, and flavanones. The results give additional support to the recommendations for a varied diet with fruits, berries, cereals, and vegetables.     

Gender and age group differences in nutrition intake and dietary quality of Korean adults eating alone: based on Korean National Health and Nutrition Examination Survey Data, 2013–2016

BACKGROUND/OBJECTIVESThis study investigated gender and age differences in nutrient intake and dietary quality of people eating alone.SUBJECTS/METHODSFrom Korean National Health and Nutrition Examination Survey 2013–2016 data, 2,305 adults aged 20 years and older that ate meals alone were included in this study. Their energy and nutrients intakes, as well as their nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ) were analyzed. Food group consumption pattern, dietary variety score (DVS), dietary diversity score (DDS) were also analyzed. All data were compared among gender and age groups.RESULTSMen consumed more energy and nutrients than women, except for vitamin C, and the NARs showed similar gender differences. The INQs of 4 nutrients (calcium, vitamin A, vitamin C, and riboflavin) were lower than 1.0 in men, whereas only the calcium INQ was lower than 1.0 in women. Men had a lower DDS (3.6) than women (3.9) (P < 0.001) and had more ‘undesirable’ food group consumption patterns than women (P < 0.001). The intakes of calcium, vitamin A, and vitamin C were relatively low in the young-aged group (INQs less than 1.0). In the old-aged group, the MAR level was relatively low, and the INQs of calcium, riboflavin, and niacin were below 1.0. The old-aged group consumed more menu items, but their DVS was the lowest.CONCLUSIONSCompared to women, the dietary quality and food diversity among men were poorer. There were poorer quality and diversity patterns in the young-aged group compared to those of the older groups. An overall low intake of nutrients and the low nutrient density of meals were the main dietary problems among the old-aged group who eat alone. Therefore, men, particularly young- and old-aged, need to be prioritized in nutritional policies directed toward those who eat alone.     

Development and Evaluation of a Diet Quality Index for Preschool-Aged Children in an Asian population: The Growing Up in Singapore Towards Healthy Outcomes cohort

BackgroundDiet quality indexes are useful tools to measure diet quality because they compare dietary intakes against recommendations. A dietary quality index for Asian preschool-aged children is lacking.ObjectiveThe aims of this study were to develop and evaluate a dietary quality index for preschool-aged children (ie, the DQI-5) based on Singapore dietary recommendations and to examine diet quality in a cohort of 5-year-old children. An additional aim was to assess associations between sociodemographic characteristics and DQI-5 scores.DesignA secondary analysis was conducted using dietary intake of children from the Growing Up in Singapore Towards healthy Outcomes mother–offspring cohort assessed in 2015-2016 using a validated food frequency questionnaire. The sociodemographic data were assessed at recruitment between June 2009 and September 2010. The DQI-5 was evaluated using a construct validity approach, whereby nutrition parameters associated with diet quality were studied.Participants and settingParticipants were 767 Singaporean children aged 5 years of Chinese, Malay, or Indian ethnicity.Main outcome measuresThe main outcome measures were the DQI-5 scores and the sociodemographic characteristics associated with diet quality.Statistical analyses performedKruskal-Wallis tests were used to evaluate differences in adherence to dietary recommendations across DQI-5 tertiles. Linear multiple regression analysis was performed to identify sociodemographic characteristics that were associated with diet quality in the children.ResultsThe DQI-5 consists of 12 food and nutrient components, with a minimum score of zero and a maximum score of 110 points. The higher scores indicate a healthier diet, the mean ± SD DQI-5 score for the children was 61.6 ± 13.2. DQI-5 components with low scores included whole grains, vegetables, and fatty acid ratio, whereas total rice and alternatives and milk and dairy products components were overconsumed by 18% and 24.4% of children, respectively. Children with higher scores were more likely to meet dietary recommendations and had higher intake of nutrients such as dietary fiber, iron, vitamin A, and beta carotene. Children whose mothers were of Malay ethnicity and whose mothers had low income, an education below university, and shared primary caregiver responsibilities were more likely to have lower DQI-5 scores.ConclusionsThe DQI-5 scores revealed diets to be low for several components and excessive for a few. The DQI-5 developed for preschool-aged children in Singapore had adequate construct validity.     

Estimated dietary intake and major food sources of polyphenols in the Polish arm of the HAPIEE study

ObjectiveThe aim of this study was to estimate the intake of known individual polyphenols and their major dietary sources in the Polish arm of the HAPIEE (Health, Alcohol and Psychosocial factors In Eastern Europe) study.MethodsA total of 10,477 random sample (45–69 y) of urban population of Krakow, Poland, completed a validated 148-item food frequency questionnaire. Polyphenol intake was calculated by matching food consumption data with the recently developed Phenol-Explorer database.ResultsThe mean intake of polyphenols was 1756.5 ± 695.8 mg/d (median = 1662.5 mg/d). The main polyphenol groups were flavonoids (897 mg/d) and phenolic acids (800 mg/d). A total of 347 polyphenols from 19 polyphenol subclasses were found. The individual compounds with the highest intakes were isomers of chlorogenic acid (i.e., 5-caffeoylquinic acid and 4-caffeoylquinic acid) among hydroxycinnamic acids (average intake 150 mg/d), that largely originated from coffee, and compounds belonging to the catechin chemical family (i.e., [+]-gallocatechin, [-]-epigallocatechin 3-O-gallate, and [-]-epicatechin) among flavanols (average intake 50 mg/d), that mostly originated from tea and cocoa products.ConclusionsThe current study provides the most updated data for individual polyphenols intake in the diet of a well-established nutritional cohort. These findings will be useful to assess potential beneficial role on health of specific foods with high polyphenol content and characterize the effects of individual phenolic compounds.
