ABSTRACT

A alergia alimentar caracteriza-se por uma reação adversa a um determinado alimento, envolvendo um mecanismo imunológico. Uma das alergias mais comuns encontradas atualmente é a alergia a frutos do mar, a qual se baseia em uma hipersensibilidade a animais desse grupo. O objetivo desta pesquisa é identificar os desafios expostos na alimentação de alérgicos a frutos do mar e formular soluções para essa população baseadas em alimentos nutricionalmente substitutos. Sendo realizado em três etapas: investigação inicial, construção de conceitos e planejamento de uma ação com orientações nutricionais. De acordo com as dificuldades encontradas na alimentação dessa parcela populacional, realizaram-se diferentes preparações, com nutrientes como ômega-3, proteínas, vitaminas do complexo B, zinco, ferro, potássio, magnésio, iodo e selênio, os quais também são encontrados nos frutos do mar, a fim de evitar possíveis contaminações cruzadas e garantir seu aporte nutricional em alimentos substitutos. Foi possível concluir que os alérgicos aos frutos do mar não apresentam uma interferência significativa em sua qualidade de vida, tendo um impacto nutricional pequeno, visto que por meio da alimentação existem outras fontes, necessitando somente de alguns cuidados no dia a dia em virtude das consequências de uma possível contaminação.


Food allergy is characterized by an adverse reaction to a given food, involving an immunological mechanism. One of the most common allergies currently found is seafood allergy, which is based on hypersensitivity to animals in this group. The objective of this research is to identify the challenges exposed in the feeding of seafood allergies and formulate solutions for this population based on nutritionally substitute foods. Being carried out in 3 stages, initial investigation, construction of concepts and planning of an action with nutritional guidance. According to the difficulties encountered in feeding this portion of the population, different preparations were carried out, with nutrients such as: ômega-3, proteins, B vitamins, zinc, iron, potassium, magnesium, iodine and selenium. Which are also found in seafood. In order to avoid possible cross-contamination and ensure their nutritional intake in substitute foods. It was possible to conclude that seafood allergies do not present a significant interference in their quality of life, having a small nutritional impact, since through food there are other sources, requiring only some care on a daily basis due to the consequences of possible contamination.

ABSTRACT

Os suplementos à base de vitamina C são amplamente consumidos pela população, evidenciando a importância da fiscalização desses produtos. Em julho de 2018, a ANVISA (Agência Nacional de Vigilância Sanitária) publicou as novas regulamentações sobre suplementos alimentares, estabelecendo-se o prazo de 60 meses para as empresas se adequarem a essas normas. O presente trabalho teve como objetivo determinar os teores de vitamina C, comparar os valores analisados com os declarados na informação nutricional e avaliar os dizeres de rotulagem em produtos à base dessa vitamina. Os teores de vitamina C foram determinados por titulação potencio métrica e as análises de rotulagem foram realizadas com base nas legislações da ANVISA em doze amostras de suplementos colhidos pelas Vigilâncias Sanitárias do Estado de São Paulo. Os teores de vitamina C avaliados estavam de acordo com os declarados na informação nutricional do rótulo, com exceção de uma amostra que apresentou teor abaixo do valor declarado. Em relação aos dizeres de rotulagem, sete amostras (58%) apresentaram um ou mais itens em desacordo com a legislação, mostrando a necessidade de monitoramento constante desse tipo de produto. O trabalho representa um estudo preliminar de avaliação dos suplementos no período de adequação às novas regulamentações (AU).


Vitamin C-based supplements are widely consumed by the population, highlighting the importance of monitoring these products. In July 2018, the ANVISA (National Health Surveillance Agency) published new regulations for dietary supplements,setting a 60 months deadline for companies to comply with these standards.The objective of the present work was to evaluate the contents of vitamin C, and compare the analyzed/real values with those reported on the nutrition facts label, and to evaluate the labeling of vitamin supplements. Vitamin C contents were determined by potentiometric titration, and labeling analysis were performed based on ANVISA legislation in twelve samples of supplements collected by the Sanitary Surveillance of the State of São Paulo.The contents of vitamin C were in accordance with those declared in the nutritional information on the label, with the exception of one sample that presented content below the declared value. Regarding the labeling analysis, seven samples (58%) presented one or more items in disagreement with the legislation, showing the need for constant monitoring of this type of product.The work represents a preliminary study to evaluate the supplements in the adequacy period of new regulations (AU).

ABSTRACT

OBJECTIVE@#To explore the association of maternal periconceptional folic acid or multiple micronutrients supplementation during periconceptional period and the serum vitamin E (Vit.E) concentration in the 1st trimester of gestational period.@*METHODS@#A retrospective cohort study was conducted based on the prenatal health care system and clinical laboratory information system. Totally, 22 171 pregnant women who had their prenatal health care and gave birth in Tongzhou Maternal & Child Health Hospital of Beijing from Jan. 2016 to Dec. 2018 were recruited. The usage patterns of nutritional supplements [folic acid (FA) or multiple micronutrients (MM)] during periconceptional period were independent variables, and serum Vit.E concentration and serum Vit.E concentration≥11.2 mg/L in the 1st trimester of gestational period were outcome variables for generalized linear regression model and Logistic regression model, respectively, to analyze the relationships between the independent and outcome variables.@*RESULTS@#The range of the serum Vit.E concentration in the 1st trimester of gestational period was 5.2-24.0 mg/L, and the median concentration was 10.1 (8.8-11.6) mg/L; the excess rate of the serum Vit.E of those who took MM supplementation was 0.3%, and the rates for the groups of FA only or no nutritional supplements used were both 0.1%. Compared with women without nutritional supplement or the women taking FA, the women who took MM had higher serum Vit.E levels in the 1st trimester of gestational period (both P < 0.05). The women taking FA or MM initiated before the conception showed that the serum Vit.E concentration in the 1st trimester of gestational period was higher than that after the conception (P < 0.05), and the serum Vit.E concentration of women who took regularly was higher than that of irregular taking (P < 0.05); with taking compliance elevated, the serum Vit.E concentration of the two groups of women taking FA or MM increased (P < 0.05). The risk of serum Vit.E concentration≥11.2 mg/L among the women taking MM was higher than that of the women without nutritional supplements or taking FA only [odds ratio (OR)=1.36, 95% confidence interval (95%CI): 1.21-1.53; OR=1.39, 95%CI: 1.31-1.48)]; women who took FA or MM showed a lower risk for serum Vit.E concentration≥11.2 mg/L of taking it after the conception than before, the ORs (95%CI) were 0.86 (95%CI: 0.77-0.96) and 0.88 (95%CI: 0.81-0.95), respectively; the women taking the two supplements regularly had higher risk for serum Vit.E concentration≥11.2 mg/L than irregular taking, the ORs (95%CI) were 1.16 (95%CI: 1.05-1.29) and 1.13 (95%CI: 1.04-1.22) for FA and MM users, respectively; with the compliance increasing, the women taking MM had a higher risk of serum Vit.E levels≥11.2 mg/L in the 1st trimester [OR (95%CI) was 1.10 (1.07-1.14)], but for FA users, the OR (95%CI) was 1.04(1.00-1.08).@*CONCLUSION@#Vit.E nutritional status in women in early gestational period in Beijing was generally good, and the excess rate of serum Vit.E was higher in women who took MM during periconceptional period than those without nutritional supplement or taking FA only, suggesting that women need to consider their own Vit.E nutritional status to choose the type of nutritional supplements during periconceptional period, so as to avoid related health hazards.

ABSTRACT

Vitamin D plays an important role in mineral and bone homeostasis, immune responses, cardiovascular function and keratinocyte proliferation and differentiation. Vitamin D performs most of its functions by binding to vitamin D receptors (VDR), which interact with other intracellular signaling pathways to regulate bone metabolism, inflammation, immunity, cell cycle progression and apoptosis. Autophagy is a basic stress response in yeast, plants and mammals, and plays a critical role in maintaining optimal functional states at the level of cells and organs. Vitamin D/VDR plays an anti-infection role via inducing and regulating autophagy.

ABSTRACT

Objective: To explore current vitamin D status and influential factors of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China. Methods: According to the "province-city-hospital" sampling technical route, a total of 1 531 healthy children under 7 years of age were sampled from 11 provinces, autonomous regions or municipalities in China by the cluster random sampling method from November 2020 to November 2021. The demographic information, family conditions, behavior and living habits and feeding behaviors were collected using unified questionnaire. Serum 25-hydroxyvitamin D(25(OH)D) levels were measured by liquid chromatography-tandem mass spectrometry. Serum 25(OH)D<30 nmol/L was considered deficient and 30-50 nmol/L was considered insufficient. With 25(OH)D≤50 nmol/L as the dependent variable, multivariate Logistic regression was applied to analyze the association between vitamin D deficiency and insufficiency and potential influential factors. Results: The prevalence of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China was 14.0% (215/1 531), 3.8% (25/664) and 21.9% (190/867) in 0-<3 and 3-<7 of age years, respectively. Compared to children aged 0-<3 years, children aged 3-<7 years had a 2.6-fold increased risk of vitamin D deficiency and insufficiency (OR=3.60, 95%CI 1.93-6.72, P<0.001). Frequent sunlight exposure (OR=0.46, 95%CI 0.29-0.73, P=0.001), vitamin D supplementation (sometimes, OR=0.33, 95%CI 0.21-0.51, P<0.001; daily, OR=0.20, 95%CI 0.11-0.36, P<0.001) and infant formula intake(4-7 times per weeks, OR=0.43, 95%CI 0.28-0.68, P<0.001) were protective factors for vitamin D deficiency and insufficiency. Conclusion: Vitamin D deficiency and insufficiency are common among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China, which is affected by age, sunlight exposure, vitamin D supplementation and infant formula intake.

ABSTRACT

OBJECTIVES@#To investigate the levels of fat-soluble vitamins A, D, and E in children with obesity and their influencing factors.@*METHODS@#A total of 273 children with obesity who attended the Department of Clinical Nutrition, Xi'an Children's Hospital, from January 2019 to April 2021 were enrolled as the obesity group. A total of 226 children with normal body weight who underwent physical examination during the same period were enrolled as the control group. Anthropometric parameters and body composition were measured for both groups, and the serum concentrations of vitamins A, D, and E were also measured.@*RESULTS@#Compared with the control group, the obesity group had significantly higher serum levels of vitamin A [(1.32±0.21) μmol/L vs (1.16±0.21) μmol/L, P<0.001] and vitamin E [(9.3±1.4) mg/L vs (8.3±1.2) mg/L, P<0.001] and a significant reduction in the level of 25-hydroxyvitamin D [(49±22) nmol/L vs (62±24) nmol/L, P<0.001]. In the obesity group, the prevalence rates of marginal vitamin A deficiency, vitamin D deficiency/insufficiency, and vitamin E insufficiency were 5.5% (15/273), 56.8% (155/273), and 4.0% (11/273), respectively. After adjustment for body mass index Z-score and waist-to-height ratio, serum vitamin A level was positively correlated with age (P<0.001), while vitamins E and 25-hydroxyvitamin D levels were negatively correlated with age in children with obesity (P<0.001). After adjustment for age, the serum levels of vitamin A, vitamin E and 25-hydroxyvitamin D were not correlated with degree of obesity, percentage of body fat, and duration of obesity in children with obesity, while the serum levels of vitamins A and E were positively correlated with waist-to-height ratio (P<0.001).@*CONCLUSIONS@#There are higher serum levels of vitamins A and E in children with obesity, especially in those with abdominal obesity, while serum vitamin D nutritional status is poor and worsens with age. Therefore, vitamin D nutritional status should be taken seriously for children with obesity, and vitamin D supplementation should be performed when necessary.

ABSTRACT

ABSTRACT BACKGROUND: Despite the several options available for supplements containing vitamins C and E, evidence regarding the prevalence of deficiency or insufficiency of these vitamins is weak. OBJECTIVES: To estimate the prevalence of deficiency or insufficiency of vitamins C and E and associated factors among women of childbearing age, in Brazil. DESIGN AND SETTING: Systematic review and meta-analysis conducted at a Brazilian public university. METHODS: A search from index inception until May 2020 was conducted. Meta-analyses were performed using inverse variance for fixed models, with summary proportions calculation using Freeman-Tukey double arcsine (base case). Reporting and methodological quality were assessed using the Joanna Briggs Institute tool for prevalence studies. RESULTS: Our review identified 12 studies, comprising 1,316 participants, especially breastfeeding women. There was at least one quality weakness in all studies, mainly regarding sampling method (i.e. convenience sampling) and small sample size. The prevalence of vitamin C deficiency ranged from 0% to 40%. Only vitamin E deficiency was synthetized in meta-analyses, with mean prevalences of 6% regardless of the alpha-tocopherol cutoff in plasma, and 5% and 16% for cutoffs of < 1.6-12.0 mmol/l and < 16.2 mmol/l, respectively. The cumulative meta-analysis suggested that a trend to lower prevalence of vitamin E deficiency occurred in recent studies. CONCLUSIONS: Although the studies identified in this systematic review had poor methodological and reporting quality, mild-moderate vitamin C and E deficiencies were identified, especially in breastfeeding women. Thus, designing and implementing policies does not seem to be a priority, because the need has not been properly dimensioned among women of childbearing age in Brazil. REGISTRATION NUMBER IN PROSPERO: CRD42020221605.

ABSTRACT

Abstract Objective To evaluate the effects of vitamin D supplementation in the postpartum period of women with previous gestational diabetes mellitus (GDM). Methods Randomized clinical trials of pregnant women with GDM of any chronological, gestational age and parity, with no history of previous disease who received vitamin D supplementation in the prenatal and/or postpartum period and were evaluated in the postpartum period were included. The PubMed, EMBASE, Cochrane, and LILACS databases were consulted until July 2019. Serum vitamin D concentration (25- hydroxyvitamin D in nmol/L), fasting blood glucose, glycated hemoglobin, serum calcium concentration, homeostatic model assessment of insulin resistance (HOMAIR), quantitative insulin sensitivity check index (QUICKI), parathyroid hormone (PTH) and body mass index (BMI) were evaluated. Similar results in at least two trials were plotted using the RevMan 5; Cochrane Collaboration, Oxford, Reino Unido. The quality of the evidence was generated according to the classification, development, and evaluation of the classification of the recommendations. Results Four studies were included in the present review (200 women). The findings indicate that there is no difference in the postpartum period in women diagnosed with previous GDM who received vitamin D supplementation in the prenatal and/or in the postpartum period, showing only that there was a significant increase in the concentration of vitamin D (relative risk [RR]: 1.85; 95% confidence interval [CI]: 1.02-2.68). Conclusion This increase in the concentration of vitamin D should be interpreted with caution, since the assessment of the quality of the evidence was very low. For the other analyzed outcomes, there was no significance between the intervention and control groups, and the outcomes, when analyzed in their strength of evidence, were considered very low and low in their evaluation.


Resumo Objetivo Avaliar os efeitos da suplementação de vitamina D no pós-parto de mulheres com diabetes mellitus gestacional (DGM) anterior. Métodos Foram incluídos ensaios clínicos randomizados com gestantes com GDM de qualquer idade cronológica, gestacional e paridade, sem história de doença prévia, que receberam suplementação de vitamina D no pré-natal e/ou no pós-parto e foram avaliadas no pós-parto. As bases de dados consultadas foram PubMed, EMBASE, Cochrane e LILACS, até julho de 2019. Foram avaliados concentração sérica da vitamina D (25-hidroxivitamina D em nmol/L), glicemia de jejum, hemoglobina glicada, concentração sérica de cálcio, modelo de avaliação da homeostase de resistência à insulina (HOMA-IR, na sigla em inglês), índice qualitativo de verificação da sensibilidade à insulina (QUICKI, na sigla em inglês), hormônio da paratireoide (PTH) e índice de massa corpórea (IMC). Resultados semelhantes em pelo menos dois ensaios foram plotados no software RevMan 5; Cochrane Collaboration, Oxford, Reino Unido. A qualidade das evidências foi gerada de acordo com a classificação, o desenvolvimento e a avaliação da classificação das recomendações. Resultados Quatro estudos foram incluídos na presente revisão (200 mulheres). Os achados indicam que não há diferença no período pós-parto em mulheres com diagnóstico prévio de DMG que receberam suplementação de vitamina D no período pré-natal e/ou pós-parto, mostrando apenas que houve um aumento significativo na concentração de vitamina D (risco relativo [RR]: 1,85; IC [intervalo de confiança] 95%: 1,02-2,68). Conclusão Este aumento na concentração de vitamina D deve ser interpretado com cautela, uma vez que a avaliação da qualidade das evidências foi muito baixa. Para os demais desfechos analisados, não houve significância entre os grupos intervenção e controle, e os desfechos, quando analisados em sua força da evidência, foram considerados muito baixa e baixa em sua avaliação.

ABSTRACT

Abstract Low bone health is associated with vitamin D deficiency in older individuals; however, this association is not well established in adults. The aim of the study was to analyze the association between serum concentrations of 25-hydroxyvitamin D and bone health in adults by systematic review and meta-analysis. The search was carried out in the LILACS, PubMed, Scopus, Web of Science, ScienceDirect databases from March 2017 to October 2018 with adult individuals (20-59 years). Bone health was evaluation performed through dual X-ray absorptiometry and serum concentrations of 25(OH)D. The random effect model was used to analyze data from bone mineral content and bone mineral. Random effects models were used and the sources of heterogeneity were explored by means of meta-regression. Thirty-five articles were selected. There was positive correlation between vitamin D and bone health in most of the evaluated sites. Correlation was observed in the analysis of subgroups for lumbar spine among men. When stratified, the studies presented high heterogeneity, which was explained by the sample size, mean serum vitamin D levels and risk of bias. Vitamin D is positively correlated to bone health in adult individuals.


Resumo A baixa saúde óssea está associada à deficiência de vitamina D em indivíduos mais velhos; no entanto, isso não está bem estabelecido em adultos. O estudo objetivou-se analisar a associação entre concentrações séricas de 25-hidroxivitamina D e baixa saúde óssea em adultos por revisão sistemática e metanálise. A pesquisa foi realizada nas bases LILACS, PubMed, Scopus, Web of Science, ScienceDirect de março de 2017 a outubro de 2018 com indivíduos adultos (20-59 anos). A avaliação da saúde óssea foi realizada através da absorciometria dupla de raios X e concentrações séricas de 25(OH)D. O modelo de efeito aleatório foi utilizado para analisar dados do conteúdo mineral ósseo e densidade mineral óssea. Modelos de efeitos aleatórios foram utilizados e a heterogeneidade foi explorada por meio de meta-regressão. Trinta e cinco artigos foram selecionados. Houve correlação positiva entre a vitamina D e a saúde óssea na maioria dos locais avaliados. Observou-se correlação na análise de subgrupos da coluna lombar entre homens. Quando estratificados, os estudos apresentaram alta heterogeneidade, explicada pelo tamanho da amostra, pelos níveis séricos médios da vitamina e pelo risco de viés. A vitamina D está positivamente correlacionada com a saúde óssea em indivíduos adultos.

ABSTRACT

ABSTRACT Objective: This meta-analysis is the first to evaluate the associations of circulating and dietary intake of vitamin D with risk of risk of renal cell carcinoma (RCC). Our findings showed that higher circulating vitamin D level and dietary vitamin D intake were associated with a reduced risk of RCC. The possible explanation might be attributed to the anti-inflammatory effect, inhibiting cell proliferation, inducing cell differentiation and apoptosis. Materials and Methods: We searched the MEDLINE, EMBASE, and Scopus databases from their inception points through December 2018 for observational studies. The pooled relative risks (RRs) with corresponding 95% CIs were calculated using random-effects or fixed-effects models. The Newcastle-Ottawa scale was employed to assess the quality of the included studies. Results: A total of 9 publications were included in this meta-analysis. An overall analysis of the highest versus lowest intake levels revealed that circulating vitamin D level was protectively associated with risk of RCC 0.76 (95% CI: 0.64-0.89, P=0.001), with no evidence of heterogeneity (I2=38.8%, P=0.162). In addition, dietary vitamin D intake was associated with a reduced risk of RCC (RR: 0.86; 95% CI: 75-0.99, P=0.030). Statistical heterogeneity was not identified (I2=28.8%, P=0.199). Subgroup analyses results showed the gender differences, and the associations were significant in results with women participants (RR: 0.70; 95% CI: 0.55-0.88) and case-control studies (RR: 0.80, 95% CI: 0.67-0.95). Conclusion: Higher circulating vitamin D level and higher dietary vitamin D intake both might be associated with a reduced risk of RCC. Further high-quality randomized controlled trials are required in the future to confirm our results.

ABSTRACT

The aim of this study was to evaluate the reasons of quality deviation of a concentrate from a predefined standard. Five treatments were established: T1 - Control, standard concentrate formulation (SCF); T2 - PXMore5, SCF with more 5% vitamin-mineral premix (VMP); T3 - PXLess5, SCF with less 5% VMP. All three treatments used a 400kg batches in an INTECNIAL mixer; T4 - FeedMixer, SCF using a 4,000kg batch in an IMOTO mixer; T5 - PremixMixer, SCF using a 1,200kg batch in an MUYANG mixer. For each treatment, bags of 20 kg were stored in three storage places for four months. Water activity of concentrate was affected by temperature and air relative humidity in different storage places. Regarding the kind of mixer, the greatest variation in concentration of crude protein, mineral residue, copper, zinc, and selenium was observed in the PremixMixer. Adjustments are imperative in the handling and use procedures of this kind of mixer to meet the quality requirements required in the concentrate production. Analyzing the effect of the mineral-vitamin premix level, no difference could be defined with the evaluated parameters.(AU)


O objetivo deste estudo foi avaliar as razões do desvio de qualidade de um concentrado de um padrão predefinido. Foram estabelecidos cinco tratamentos: T1 - controle, concentrado com formulação padrão (CFP); T2 - PXMais5, CFP com 5% a mais de vitaminas e minerais da pré-mistura (PVM); T3 - PXMenos5, CFP com 5% a menos de PVM. Todos esses três tratamentos utilizaram lotes de 400kg em um misturador INTECNIAL; T4 - FeedMixer, CFP usando um lote de 4.000kg em um misturador IMOTO; T5 - PremixMixer, CFP usando um lote de 1.200kg em um misturador MUYANG. Para cada tratamento, sacos de 20kg foram armazenados em três ambientes distintos por quatro meses. A atividade de água do concentrado foi afetada pela temperatura e umidade relativa do ar em diferentes locais de armazenamento. Em relação ao tipo de misturador, a maior variação na concentração de proteína bruta, resíduo mineral, cobre, zinco e selênio foi devido ao PremixMixer. Ajustes são imperativos nos procedimentos de manuseio e uso desse tipo de misturador para atender aos requisitos de qualidade exigidos na produção de concentrado. Ao se analisar o efeito do nível da pré-mistura de vitaminas e minerais, nenhuma diferença pôde ser definida com os parâmetros avaliados.(AU)

RESULTADOS: Foram selecionados 102 artigos, dos quais após análise dos critérios de exclusão e inclusão, resultaram em 31 artigos referentes a 31,62% da amostra inicial que foram utilizados para a produção dessa revisão. CONCLUSÃO: O acompanhamento nutricional do paciente com DMD é fundamental, de forma a garantir a manutenção do estado nutricional, além de contribuir de forma significativa para a desaceleração dos sintomas da doença e melhora da qualidade de vida.


OBJECTIVE: To search for nutritional recommendations for patients with Duchenne Muscular Dystrophy (DMD). METHOD: It is an integrative review of the literature, through a bibliographic survey on the scientific bases PubMed and Scielo, the keywords used were Duchenne Muscular Dystrophy in combination with the terms Nutrition, Nutrients, Nutraceuticals, Vitamins and Antioxidants. The search was based on articles published in the last 10 years. RESULTS: A total of 102 articles were selected, of which, after analyzing the exclusion and inclusion criteria, resulted in 32 articles referring to 32.64% of the initial sample that were used to produce this review. CONCLUSION: Nutritional monitoring of patients with DMD is essential, in order to guarantee the maintenance of nutritional status, in addition to contributing significantly to the deceleration of the symptoms of the disease and improving the quality of life.

ABSTRACT

Resumo O estudo avaliou a viabilidade da adequação de cardápios em relação às exigências nutricionais estabelecidas pelo Programa Nacional de Alimentação Escolar (PNAE) e a relação entre o custo do cardápio. Cada cardápio semanal contou de uma combinação de alimentos dentro de cada grupo. Para cada combinação de alimentos foi elaborado um modelo de otimização de dados para obter as quantidades de cada alimento de forma a atender às exigências do PNAE ao menor custo possível (cardápios com 20% e 30% da ingestão dietética de referência para energia, macronutrientes, cálcio, ferro, magnésio, zinco, vitaminas A e C, além de restrições para sódio, gorduras saturada e trans, e açúcar de adição). Não foi obtida nenhuma solução que acomodasse todas as exigências do PNAE. Os componentes limitantes foram cálcio, sódio e carboidratos; para os demais os cardápios foram adequados. O custo foi diretamente correlacionado com a frequência de carne e frutas, e inversamente com os conteúdos de sódio e carboidratos, e com as frequências de arroz e feijão. A probabilidade de adequação de carboidratos foi próxima de zero quando a frequência de carne foi acima de 1 vez por semana. Concluindo, é pouco provável a obtenção de cardápios que atendam à todas as exigências do PNAE.


Abstract We evaluated the feasibility of the menu adequacy regarding the nutritional constraints established by the National School Feeding Program (PNAE) and its relation to the cost. Each menu accounted for a given food combination within each food group. A diet optimization model comprising each set of foods was designed to obtain food quantities in order to meet the exigences of the PNAE at the lowest cost (menus with 20% and 30% of dietary reference intake for energy, macronutrients, calcium, iron, magnesium, zinc, vitamins A and C, also restrictions for sodium, saturated and trans fats, and added sugar). There was no feasible solution that accommodated all nutrient targets. Limiting components were calcium, sodium, and carbohydrates; but the menus were adequate for the other nutrients. There was a positive correlation between the menu cost and the frequency of meat and fruits, and a negative correlation with the contents of sodium and carbohydrates, and with the frequencies of rice and beans. The probability of obtaining carbohydrate adequacy was close to zero when the meat frequency was higher than one serving per week. In conclusion, it is unlikely to obtain menus that meet all the requirements of the PNAE.

ABSTRACT

ABSTRACT Objective: To evaluate the potential effect of poly-vitamins and probiotics use among preschool children permanently living within iodine deficiency territory on caries prevention. Material and Methods: 80 children aged 2-3 years old were randomly distributed among the study group (21 male and 19 females) and control group (20 males and 20 females). Oral fluid samples were formed from each study subject during primary examination and after 1 year of monitoring, which further were analyzed by parameters associated with mineralization potential of oral fluid. Both groups were provided with oral hygiene educational training, while the study group was also prescribed with poly-vitamin-mineral drug complex and probiotics. Results: After 1 year of monitoring, no significant changes considering caries prevalence (p>0.05) or intensity (p>0.05) values were registered among study and control groups. Difference of free calcium level, phosphate ion level and alkaline phosphatase activity was statistically approved (p<0.05) while comparing between study and control group after 12 months of monitoring. Conclusion: Caries preventive approach consisted of oral hygiene educational training and course of properly prescribed poly-vitamins and probiotics intake demonstrates positive results related to the changes within mineralization potential of oral fluid among preschool children with long-term residence over geographically associated iodine-deficient territory.
