RESUMO
Nutrient adequacy among adolescents is of concern due to higher nutrient requirements for their developing bodies as well as the gap between the current nutrient intake and the recommendations. The objective of this study was to determine beef intake and assess the relationship between beef consumption and nutrient intake and nutrient adequacy in male and female adolescents, 14-18 years of age. Dietary recalls collected during the What We Eat in America (WWEIA) portion of the National Health and Nutrition Examination Survey (NHANES) cycles 2001-2018 were utilized to determine beef intake. Usual nutrient intakes were determined with the National Cancer Institute method in conjunction with day 1 and day 2 total nutrient files. Nutrient adequacy was assessed by calculating the percentage of the population below the estimated average requirement (EAR) or above the adequate intake (AI). The average beef intake of male and female adolescent beef consumers was 57.9 ± 2.4 and 46.8 ± 2.2 g with a 90th percentile of 82.3 ± 4.3 and 67.8 ± 3.5 g, respectively. Compared to non-consumers, beef consumers had a 10% or higher intake of calcium, iron, phosphorus, potassium, total choline, vitamin B12, and zinc. Over 50% of the adolescent population (regardless of beef consumption) had intakes below the EAR for calcium, magnesium, and vitamins A, C, D, and E. The percentage of the beef-consuming population below the EAR was lower for calcium, copper, folate, iron, phosphorus, zinc, and vitamins B12 and B6 as compared to non-consumers. Additionally, the portion of the population above the AI for sodium was higher in female beef consumers as compared to non-consumers. We estimate approximately 900,000 to 1,400,000, 400,000-700,000, 200,000-600,000, and 200,000-400,000 fewer adolescents to be below the EAR for zinc, phosphorus, vitamin B12, and iron, respectively if beef non-consumers were to consume beef. This study suggests beef can help increase the nutrient intake and nutrient adequacy in the diets of adolescents, helping to close important gaps for this nutritionally vulnerable population. While recommendations to reduce beef intake are widely prevalent, this could result in unintended nutritional consequences regarding under-consumed nutrients including those of public health concern important for adolescent health.

Pork is a rich source of high-quality protein and select nutrients. The objective of this work was to assess the intakes of all pork (AP), fresh pork (FP) and processed pork (PP) and their association with nutrient intake and meeting nutrient recommendations using 24 h dietary recall data. Usual intake was determined using the NCI method and the percentage of the population with intakes below the Estimated Average Requirement, or above the Adequate Intake for pork consumers and non-consumers, was estimated. About 52, 15 and 45% of children and 59, 20 and 49% of adults were consumers of AP, FP and PP, respectively, with mean intakes in consumers of 47, 60 and 38 g/day for children and 61, 77 and 48 g/day for adults, respectively. Among consumers of AP, FP and PP, the intakes of copper, potassium, selenium, sodium, zinc, thiamine, niacin, vitamin B6 and choline were higher (p < 0.05) and a higher (p < 0.05) proportion met nutrient recommendations for copper, potassium, zinc, thiamin and choline compared to non-consumers. There were additional differences (p < 0.05) in intakes and adequacies for other nutrients between consumers and non-consumers depending upon the age group and pork type. In conclusion, pork intake was associated with higher intakes and adequacies in children and adults for certain key nutrients.

Background: Replacing some animal sources of protein with plant foods is encouraged. Nutrient intake may reflect changes in the protein source. The adequacy of habitual nutrient intake among US adults has not been evaluated by the level of animal protein (AP) intake. Objectives: The objective of this study was to compare food consumption and nutrient intake and adequacy among quintiles of percent AP intake. Methods: Dietary intake data of adults 19+ y (N = 9706) from What We Eat in America, National Health and Nutrition Examination Survey 2015-2018 were used. Proportions of protein from animal and plant sources were estimated from ingredients in the Food and Nutrient Database for Dietary Studies 2015-2018, and then applied to dietary intakes. Intakes were classified by Q of percent AP. Food intake was described using the United States Department of Agriculture Food Patterns components. Usual nutrient intakes were estimated using the National Cancer Institute Method and compared with age and gender-specific Dietary Reference Intakes (DRIs). Comparisons between quintiles were made using t-tests. Results were considered significant at P < 0.01. Results: Total protein intake was higher as the Q of AP intake increased. Among the higher quintiles of percent AP, <1% did not meet their DRIs for protein than 17% in Q1 and 5% in Q2 (P < 0.01). In quintiles with lower compared with higher percent AP, there were significantly higher percentages not meeting DRIs for vitamins A, B12, choline, zinc, and calcium but meeting recommendations for folate, vitamin C, saturated fat, cholesterol, and fiber (P < 0.01). Among all quintiles, over one-third did not meet DRIs for fiber, vitamins A, C, D, E, K, choline, calcium, and potassium. Conclusions: Replacing protein from animal sources with plant foods may result in lower intakes of protein and some nutrients but a better intake of dietary components associated with reducing chronic disease risk. The current intake of US adults indicates dietary improvements are needed, regardless of protein source.
RESUMO
BACKGROUND: Americans are underconsuming essential nutrients while overconsuming several nutrients, including sodium, saturated fat, and added sugars. Suboptimal nutrition may be linked with mortality risk; however, few studies have evaluated the associations of underconsumed and overconsumed nutrients in a comprehensive manner among the US population. OBJECTIVES: This study investigated the association between nutrient intake through diet and mortality focusing on adequacy, moderation, and macronutrient quality in US adults. METHODS: Based on the 1999-2010 NHANES, 20,602 adults aged ≥30 y were followed up until December 2015. Nutrient intake was assessed using a 1-d 24-h dietary recall. Adequacy of major underconsumed nutrients in the United States was evaluated using the RDA (percent of RDA) or Adequate Intake (percent of AI). Overconsumed nutrients for which moderation is needed were assessed based on various dietary recommendations. Macronutrient quality was evaluated using the ratio of carbohydrates to dietary fiber, essential amino acids, and EPA + DHA. The association between nutrient intake and mortality was evaluated using Cox proportional hazards regression analysis. RESULTS: Higher intakes of vitamin E, magnesium, iron, dietary fiber, and potassium relative to the RDA/AI were associated with lower all-cause mortality. High intake of vitamin A (tertile 3: ≥80.1% of RDA) was associated with lower mortality from cardiovascular disease (CVD; HR: 0.75; 95% CI: 0.57, 0.99) and cancer (HR: 0.76; 95% CI: 0.62, 0.94), and high intake of calcium (tertile 3: ≥87.8% of RDA) was inversely associated with cancer mortality (HR: 0.72; 95% CI: 0.56, 0.93). Higher intakes of essential amino acids and EPA + DHA evaluated as quartiles were inversely associated with all-cause and CVD mortality. CONCLUSIONS: These findings suggest that higher intakes of underconsumed nutrients and improving macronutrient quality are associated with lower risk of CVD and cancer deaths in US adults.

BACKGROUND: Accurate estimates of the usual intake of nutrients are important for monitoring nutritional adequacy and diet quality of populations. In Canada, comprehensive, nationally representative nutrient estimates have not been available since the Canadian Community Health Survey (CCHS)-Nutrition 2004 survey. OBJECTIVE: The objective of this research was to assess nutrient intakes, distributions, and adequacy of the intakes of Canadian adults. METHODS: Participants' first 24-h dietary recall, and the second-day recall from a subset of participants from the recently released CCHS 2015 Public Use Microdata File (PUMF) were used to estimate usual intakes of macronutrients, vitamins, and minerals in adults [≥19 y, excluding lactating females and those with invalid energy intake (EI)]. Usual intakes by DRI age-sex groups were estimated using the National Cancer Institute method, adjusted for age, sex, misreporting status, weekend/weekday, and sequence of recall analyzed (first/second) with outliers removed (final sample, n = 11,992). Usual intakes from food were assessed for prevalence of inadequacy in relation to DRI recommendations. RESULTS: Canadian macronutrient intakes were within the recommended acceptable macronutrient distribution ranges. EI was 2154 kcal/d for males (19+) and 1626 kcal/d for females (19+). A high prevalence of inadequate intakes was seen for vitamin A (>47%), vitamin D (>94%), vitamin C (>29% for nonsmokers and >59% for smokers), magnesium (>45%), and calcium (>44%), whereas <25% and <40% of adults (19+) had intakes above the adequate intake for fiber and potassium, respectively. Canadians continue to consume sodium in excess of recommendations (74.8% of males and 47.6% of females). CONCLUSIONS: A significant number of Canadian adults may not be meeting recommendations for several essential nutrients, contributing to nutrient inadequacies. These results highlight the nutrients of concern by specific age-sex groups that may be important for public health interventions aimed at improving diet quality and nutrient adequacy for Canadian adults.

BACKGROUND AND AIMS: Previous studies, mainly focused on quantity rather than variety, have shown beneficial associations between the amount of fruit and vegetable consumed, diet quality and healthy lifestyle. The aim is to evaluate the association between fruit and vegetable consumption, diet quality and lifestyle in an elderly Mediterranean population, considering both variety and the combination of quantity and variety (QV). METHODS: A cross-sectional analysis of 6647 participants (51.6% of males) was conducted in the framework of the PREDIMED-Plus study. A variety score was created as the sum of vegetables and/or fruits consumed at least once per month using food frequency questionnaires. Dietary Reference Intakes (EAR and IA values) were used to estimate the prevalence of inadequate intake of dietary fiber and micronutrients. Logistic regression models were performed to examine the association between fruit and vegetable consumption and not meeting the DRIs, by tertiles of fruit and vegetable variety and QV categories. RESULTS: Participants with higher fruit and vegetable variety score reported a significant higher intake of fiber, vitamins, minerals and flavonoids and were significantly more likely to be physically active and non-smoker. Besides, higher variety in fruit and vegetable consumption was associated with lower prevalence of having an inadequate intake of fiber [(0.13 (0.11-0.16)], two or more [(0.17 (0.14-0.21)], three or more [(0.15 (0.13-0.18)] and four or more [(0.11 (0.10-0.14)] micronutrients in our participants. Higher quantity and variety in fruit and vegetable consumption was associated with lower prevalence of having an inadequate intake of fiber [(0.05 (0.04-0.06)], two or more [(0.08 (0.06-0.10)], three or more [(0.08 (0.06-0.09)] and four or more [(0.06 (0.05-0.07)] micronutrients. CONCLUSION: Greater variety in fruit and vegetable intake was associated with better nutrient adequacy, diet quality and healthier lifestyle in an elderly Mediterranean population.

PURPOSE: This study aimed at assessing nutrient adequacy after 1 year in patients who had undergone gastric bypass (GB) surgery or sleeve gastrectomy (SG) and to investigate the association of nutrient adequacy with anthropometric indices. METHODS: A total of 180 severely obese patients (BMI ≥ 35 kg/m2) were selected among the participants of Tehran Obesity Treatment Study. Nutritional assessments were performed over 3 days of 24-h dietary recall. To evaluate the nutrient adequacy ratio (NAR), the subject's nutrient intake was divided by the dietary reference intakes. The mean adequacy ratio (MAR) was also determined as the sum of NARs divided by the number of involved nutrients (n = 11). RESULTS: The mean age of SG (67%) and GB (32%) patients was 39.2 ± 12 and 41.4 ± 10 years, respectively. SG patients had more postoperative fat-free mass (52.0 ± 12 kg) than GB patients (49.7 ± 8 kg) (P < 0.05). The most common postoperative serum nutrient deficiencies were related to vitamin B12 (30%), ferritin (19%), and 25-hydroxyvitamin D (16.2%). Moreover, high inadequacy of protein (> 80%) and total fat (> 70%) intake was reported. The MAR score showed that almost 45% of the patients had possibly adequate intakes of some nutrients. The adequacy of nutrients was positively associated with fat-free mass (ß = 8.67, P < 0.05). CONCLUSION: These findings revealed that patients had inadequate nutrient intakes 1 year after bariatric surgery, which was accompanied by serum nutritional deficiencies. Compared to GB patients, SG patients had a better body composition. Overall, compliance of patients with dietary guidelines and supplementations needs to be carefully monitored in the postoperative period.

Background: Increased soft-drink consumption has contributed to poor calcium intake with 90% of adolescent girls consuming less than the RDA for calcium.Purpose/objectives: The purpose of this investigation was to determine the independent and additive effects of two interventions (milk and resistance training) on nutrient adequacy, body composition, and bone health in adolescent girls.Methods: The experimental design consisted of four experimental groups of adolescent girls 14-17 years of age: (1) Milk + resistance training [MRT]; n = 15; (2) Resistance training only [RT]; n = 15; (3) Milk only [M] n = 20; (4) Control [C] n = 16. A few significant differences were observed at baseline between the groups for subject characteristics. Testing was performed pre and post-12 week training period for all groups. Milk was provided (3, 8 oz servings) for both the MRT and the M groups. The MRT group and the RT groups performed a supervised periodized resistance training program consisting of supervised one-hour exercise sessions 3 d/wk (M, W, F) for 12 wk. Baseline dietary data was collected utilizing the NUT-P-FFQ and/or a 120 item FFQ developed by the Fred Hutchinson Cancer Research Center (Seattle, Washington). Body composition was measured in the morning after an overnight fast using dual-energy X-ray absorptiometry (DXA) with a total body scanner (ProdigyTM, Lunar Corporation, Madison, WI). A whole body scan for bone density and lumbar spine scans were performed on all subjects. Maximal strength of the upper and lower body was assessed via a one-repetition maximum (1-RM) squat and bench press exercise protocols. Significance was set at P ≤ 0.05.Results: Significant differences in nutrient intakes between groups generally reflected the nutrient composition of milk with greater intakes of protein and improved nutrient adequacy for several B vitamins, vitamin A, vitamin D, calcium, magnesium, phosphorus, potassium, and zinc. Mean calcium intake was 758 and 1581 mg/d, in the non-milk and milk groups, respectively, with 100% of girls in the milk groups consuming > RDA of 1300 mg/d. There were no effects of milk on body composition or muscle performance, but resistance training had a main effect and significantly increased body mass, lean body mass, muscle strength, and muscle endurance. There was a main effect of milk and resistance training on several measures of bone mineral density (BMD). Changes in whole body BMD in the M, RT, MRT, and CON were 0.45, 0.52, 1.32, and -0.19%, respectively (P < 0.01).Conclusions: Over the course of 12 weeks the effects of 1300 mg/d of calcium in the form of fluid milk combined with a heavy resistance training program resulted in the additive effects of greater nutrient adequacy and BMD in adolescent girls. While further studies are needed, combining increased milk consumption with resistance training appears to optimize bone health in adolescent girls.

Dietary diversity (DD) is a key component of a high-quality diet, providing the adequate nutrient requirements. However, the role of DD on prostate cancer (PCa) is still uncertain. The aim of this study was to evaluate the relationship between DD, adequate nutrient intake and PCa, according to the aggressiveness of the tumor. The CAPLIFE (CAP: prostate cancer; LIFE: lifestyles) study is a population-based case-control study including a total of 402 incident PCa cases and 302 controls. The DD score (DDS), adjusted by total energy intake, was collected through a validated food frequency questionnaire. Nutrient adequacy was defined according to European Dietary Recommendation Intake for men. The aggressiveness of PCa was determined according to the International Society of Urology Pathology classification. The association between DDS, nutrient intake and PCa was assessed by logistic regression models with adjustment for potential confounding factors. DDS was similar for PCa cases and controls, independent of PCa aggressiveness. According to each food group DDS, the protein group showed the highest mean score in all the subgroups analyzed. However, no differences were observed for each of the DDS components. The DDS, the variety of the group's food intake, and the adequate nutrient intake, were not associated with PCa.

ABSTRACT Objective To determine intuitive eating in young adults and the effects of factors such as gender, Body Mass Index and dietary intake, and dietary adequacy on intuitive eating. Methods This cross-sectional study was conducted with students at Gazi University in Ankara (N=665; 17.6% men; 82.4% women). The questionnaire, including the general characteristics, anthropometric measurements, Intuitive Eating Scale-2, and 24-H Dietary Recall sections, were applied to all participants. For the evaluation of the diet, Nutrient Adequacy Ratio and Mean Adequacy Ratio were used. Results The mean Intuitive Eating Scale-2 score was 3.2±0.33; men's and women's scores were 3.3±0.37 and 3.2±0.32, respectively (p<0.05). According to linear regression analysis, gender, age and mean adequacy ratio had an effect on the model for the score (p<0.05). In addition, there was a negative correlation between Intuitive Eating Scale-2 scores and Body Mass Index values in women (rp=-0.095, p=0.026). Conclusion The intuitive eating scores varied according to gender, dietary adequacy and age. Intuitive eating may be effective in the formation of long-term behavioral changes, which is beneficial for the treatment of obesity. The result of this study may encourage the development of this behavior in groups (may vary according to gender), that is thought to be effective by considering the changes of intuitive eating behavior.
RESUMO Objetivo Determinar a alimentação intuitiva em adultos jovens e os efeitos de fatores como sexo, índice de massa corporal, ingestão alimentar e adequação da dieta na alimentação intuitiva. Métodos Este estudo transversal foi realizado em estudantes da Universidade de Gazi, em Ancara (N=665; 17,6% homens; 82,4% mulheres). O questionário, incluindo as características gerais, medidas antropométricas, Escala de Alimentação Intuitiva 2 e recordatório alimentar de 24 horas foi aplicado aos participantes. Para a avaliação da dieta, foram utilizados o Índice de Adequação de Nutrientes e a Razão de Adequação Média. Resultados A Escala Média de Escala de Comportamento Intuitivo-2 foi de 3,2±0,33, dos homens e das mulheres, foi de 3,3±0,37 e 3,2±0,32, respectivamente (p<0,05). De acordo com a análise de regressão linear, sexo, idade a Razão de Adequação Média tiveram efeito no modelo formado pelo escore (p<0,05). Além disso, houve uma correlação negativa entre os escores da Escala de Alimentação Intuitiva-2 e os valores do índice de massa corporal nas mulheres (rp=-0,095, p=0,026). Conclusão Os escores alimentares intuitivos variaram de acordo com o gênero, com adequação da dieta e com a idade. A alimentação intuitiva pode ser eficaz na formação de mudanças a longo prazo no comportamento, o que é benéfico para o tratamento da obesidade. O resultado deste estudo pode encorajar o desenvolvimento deste comportamento em grupos (talvez variar de acordo com o gênero) que é considerado efetivo considerando-se as mudanças do comportamento alimentar intuitivo.

BACKGROUND: The early childhood years represent a period of rapid growth and development characterised by unique requirements for energy and individual nutrients. METHODS: The present study uses data from the National Pre-School Nutrition Survey, a nationally representative sample of Irish children (1-4 years) (n = 500), aiming to estimate energy and nutrient intakes across age and compliance with recommendations (UK and European). A 4-day weighed food-record was used to collect dietary data and statistical modelling (National Cancer Institute method) was applied to estimate usual nutrient intakes. RESULTS: Intakes of carbohydrate [48-50% energy (E)], protein (15-16%E), total fat (32-34%E), dietary fibre (2.5 g MJ-1 ), α-linolenic acid (0.45%E) and most micronutrients were in good compliance with recommendations. However, intakes of long chain polyunsaturated fatty acids (LCPUFA) (65-80 mg) were low and significant proportions of children had inadequate intakes (< estimated average requirement) of vitamin D and iron. Small proportions of children with intakes exceeding the upper level for retinol, folic acid, zinc, copper and iodine, are unlikely to give rise to adverse health effects. Mean intakes of free sugars (12%E) and salt (3.1 g day-1 ) exceeded recommendations and increased with age, whereas mean intake of saturated fat (15%E) decreased with age. By the age of 4 years, patterns established for intakes of salt, saturated fat and free sugars were unfavourable and similar to those observed in the diets of older children. CONCLUSIONS: Further research is needed to identify dietary strategies that improve the quality of the diet in young children, particularly in relation to excess of saturated fat, free sugars and salt, as well as inadequacy of iron, vitamin D and LCPUFA.

BACKGROUND: Plant protein intake, which is favorably associated with the intake of many nutrients, is a marker of a healthy diet. However, the higher nutrient adequacy of diets rich in plant protein may also originate from overarching factors associated with more healthful dietary behaviors, such as a greater dietary diversity. OBJECTIVE: Our main objective was to determine whether the relation between plant protein intake and nutrient adequacy could be explained, at least in part, by an association with overall dietary diversity. METHODS: We used data from 1330 adults participating in the French Nutrition and Health Survey [Etude Nationale Nutrition Santé (ENNS); 2006-2007]. With the use of global, integrative approaches, we assessed nutrient adequacy [by using the probabilistic PANDiet (Probability of Adequate Nutrient Intake) scoring system] and overall dietary diversity (by using a 100-point score that accounts for the relative number of subgroups consumed in 7 food groups). Linear multivariate modeling was used for the analysis. RESULTS: We found a positive association between plant protein (but not total or animal protein) intake and dietary diversity (ß = 0.08) and a strong positive association between dietary diversity and nutrient adequacy (ß = 0.33). However, the association between plant protein intake and nutrient adequacy was not explained by dietary diversity (r = 0.38 and partial r = 0.36, P < 0.0001). In multivariate analysis, nutrient adequacy was positively associated with dietary diversity (ß = 0.44) and plant (ß = 0.37) and animal (ß = 0.15) protein intakes. Associations persisted after adjustment for potential confounders (total energy, energy density, sex, body mass index, income, occupational status, educational level, region, season, and smoking status). CONCLUSIONS: Overall dietary diversity is greater in French adults who consume more plant protein. Both plant protein intake and dietary diversity are associated with the nutrient adequacy of the diet. But the plant protein-nutrient adequacy association was not related to the relative overall diversity of the diet.

BACKGROUND: To our knowledge, few studies have described the usual nutrient intakes of US children aged <2 y or assessed the nutrient adequacy of their diets relative to the recommended Dietary Reference Intakes (DRIs). OBJECTIVE: We estimated the usual nutrient intake of US children aged 6-23 mo examined in NHANES 2009-2012 and compared them to age-specific DRIs as applicable. DESIGN: Dietary intake was assessed with two 24-h recalls for infants aged 6-11 mo (n = 381) and toddlers aged 12-23 mo (n = 516) with the use of the USDA's Automated Multiple-Pass Method. Estimates of usual nutrient intakes from food and beverages were obtained with the use of the National Cancer Institute method. The proportions of children with intakes below and above the DRI were also estimated. RESULTS: The estimated usual intakes of infants were adequate for most nutrients; however, 10% had an iron intake below the Estimated Average Requirement (EAR), and only 21% had a vitamin D intake that met or exceeded the recommended Adequate Intake (AI). More nutrient inadequacies were noted among toddlers; 1 in 4 had a lower-than-recommended fat intake (percentage of energy), and most had intakes that were below the EAR for vitamins E (82%) and D (74%). Few toddlers (<1%) met or exceeded the AI for fiber and potassium. In contrast, 1 in 2 had sodium intakes that exceeded the Tolerable Upper Intake Level (UL); ≥16% and 41% of the children had excessive intakes (greater than the ULs) of vitamin A and zinc, respectively. CONCLUSIONS: The estimated usual intakes of infants were adequate for most nutrients. Most toddlers were at risk for inadequate intakes of vitamins D and E and had diets low in fiber and potassium. The sources contributing to excessive intakes of vitamin A and zinc among infants and toddlers may need further evaluation.

OBJECTIVE: To compare estimates from one day with usual intake estimates to evaluate how the adjustment for within-person variability affected nutrient intake and adequacy in Mexican children. DESIGN: In order to obtain usual nutrient intakes, the National Cancer Institute's method was used to correct the first 24 h dietary recall collected in the entire sample (n 2045) with a second 24 h recall collected in a sub-sample (n 178). We computed estimates of one-day and usual intakes of total energy, fat, Fe, Zn and Na. SETTING: 2012 Mexican National Health and Nutrition Survey. SUBJECTS: A total of 2045 children were included: 0-5·9 months old (n 182), 6-11·9 months old (n 228), 12-23·9 months old (n 537) and 24-47·9 months old (n 1098). From these, 178 provided an additional dietary recall. RESULTS: Although we found small or no differences in energy intake (kJ/d and kcal/d) between one-day v. usual intake means, the prevalence of inadequate and excessive energy intake decreased somewhat when using measures of usual intake relative to one day. Mean fat intake (g/d) was not different between one-day and usual intake among children >6 months old, but the prevalence of inadequate and excessive fat intake was overestimated among toddlers and pre-schoolers when using one-day intake (P6 months. CONCLUSIONS: There was overall low variability in energy and fat intakes but higher for micronutrients. Because the usual intake distributions are narrower, the prevalence of inadequate/excessive intakes may be biased when estimating nutrient adequacy if one day of data is used.

BACKGROUND: Meals served at government-run day care centers must be nutritionally adequate to ensure good health and proper development of preschool-aged children. They can provide a controlled opportunity to complement the daily diet of children in vulnerable populations. OBJECTIVE: To determine the nutrient adequacy and leading food sources of nutrients provided by the diet served in government-sponsored day care centers. METHODS: Estimated daily energy and nutrient intakes of a theoretical 40-day day care center menu were calculated, and the nutrient adequacy was assessed. Nutrient densities and critical nutrient densities of the menu were computed to identify nutrient inadequacies. Furthermore, main sources of nutrients were identified, and energy and nutrient distributions were examined by meal time. RESULTS: The menu provides approximately 90% of daily energy requirement and more than 100% of Recommended Nutrient Intakes (RNIs), with the exception of vitamin D and calcium. Sugar was the first leading source of energy, whereas milk was the first leading contributor of vitamin D. CONCLUSION: Within an environment of budgetary constraints, the Guatemalan government developed and advocated an exemplary menu offering for children in the vulnerable preschool period. We have demonstrated that, if prepared and served as planned, the items from the official, standard menu would supply most of the nutrients needed. High vitamin A intake related to the mandated national fortification program is a potential problem. From the analysis, it was found that vitamin D emerges as the most prominent candidate for a problem nutrient of deficient intake.

Adequate nutrition is critical to child development and institutions such as day-care centers could potentially complement childrens diets to achieve optimal daily intakes. The aim of the study was to describe the full-day diet of children, examining and contrasting the relative contribution of home-derived versus institutional energy and nutrient sources. The present comparison should be considered in the domain of a case-study format. The diets of 33, 3-6 y old children attending low-income day-care centers serving either 3 or a single meal were examined. The home-diet was assessed by means of 3 non-consecutive 24-hr recalls. Estimated energy and nutrient intakes at the centers and at home were assessed and related to Recommended Nutrient Intakes (RNI). Nutrient densities, critical densities and main sources of nutrients were computed. We observed that in children attending the day-care center serving three meals, home-foods contributed less than half the daily energy (47.7%) and between 29.9% and 53.5% of daily nutrients. In children receiving only lunch outside the home, energy contribution from the home was 83.9% and 304 kcal lower than for children receiving 3 meals. Furthermore, between 59.0% and 94.8% of daily nutrients were provided at home. Daily energy, nutrient intakes and nutrient densities were well above the nutrient requirements for this age group, and particularly high for vitamin A. The overall dietary variety was superior in the situation of greater contribution of home fare, but overall the nutrient density and adequacy of the aggregate intakes did not differ in any important manner.
Ingesta diaria de alimentos y nutrientes provenientes de la dieta institucional y del hogar en niños que asisten a dos centros de cuidado infantil contrastantes en la ciudad de Guatemala. Una adecuada nutrición es crítica para el desarrollo infantil. Los centros de cuidado infantiles (CCI) podrían jugar un papel fundamental en la complementación de la ingesta de alimentos y nutrientes. El propósito de este estudio fue describir la dieta de niños, comparando la contribución relativa de energía y nutrientes de la dieta-hogar e institucional. El presente estudio debe ser considerado como una presentación de caso. Se examinó la dieta de 33 niños de 3-6 años que asisten a dos CCI utilizados por familias de escasos recursos y con diferencias en número de comidas servidas. Se determinó la dieta-hogar utilizando 3 recordatorios de 24-horas en días no-consecutivos. Se calculó la ingesta estimada de energía y nutrientes en las instituciones y en casa y se comparó con las Ingestas Recomendadas de Nutrientes. Se determinó la densidad de nutrientes y principales fuentes. Se observó que los alimentos consumidos en el hogar contribuyeron 47.7% de la energía diaria y entre 29.9% y 53.5% de los nutrientes diarios requeridos para los niños con 3 comidas en el CCI y de 83.9%, 59.0 y 94.8%, respectivamente, para los niños que consumen únicamente el almuerzo en el CCI. La ingesta diaria de energía fue 304 kcal mayor en los niños que consumieron 3 comidas fuera del hogar. No hubo mayor variación en las dietas cuando mayor era el consumo de alimentos en el hogar, sin embargo la densidad nutricional y la adecuación de la dieta completa fue adecuada en ambos centros, y particularmente elevadas para la vitamina A.
