The role of the concomitant intake of zinc, potassium, calcium, and magnesium in the glycemic control of individuals with type 2 diabetes mellitus (T2DM) has not been extensively discussed. We evaluated the relationship between the dietary intake of these micronutrients and glycemic markers in 95 individuals with T2DM (mean age 48.6 ± 8.4 years). Hierarchical grouping analysis was used to divide the individuals into two clusters according to their micronutrient intake, and differences between clusters were statistically assessed. Effects of individual and combination intake of micronutrients on glycated hemoglobin percentage (%HbA1c) were assessed using multiple linear regression and binary logistic regression analysis. We observed a high likelihood of inadequate intake of the four micronutrients. The group with lower micronutrient intake (cluster 1) displayed higher %HbA1c (p = 0.006) and triglyceride (p = 0.010) levels. High %HbA1c showed an association with cluster 1 (odds ratio (OR) = 3.041, 95% confidence interval (CI) = 1.131; 8.175) and time of T2DM diagnosis (OR = 1.155, 95% CI = 1.043; 1.278). Potassium (β = −0.001, p = 0.017) and magnesium (β = −0.007, p = 0.015) intakes were inversely associated with %HbA1c. Reduced concomitant intake of the four micronutrients studied proved to be associated with risk of increased %HbA1c in individuals with T2DM, which was particularly predicted by magnesium and potassium intakes.

Children are in the risk group for developing hypovitaminosis D. Several strategies are used to reduce this risk. Among these, fortification of foods with vitamin D (25(OH)D) has contributed to the achievement of nutritional needs. This systematic review aims to discuss food fortification as a strategy for maintenance or recovery of nutritional status related to vitamin D in children. The work was developed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and registered in the International prospective register of systematic reviews (PROSPERO) database (CRD42018052974). Randomized clinical trials with children up to 11 years old, who were offered vitamin D-fortified foods, and who presented 25(OH)D concentrations were used as eligibility criteria. After the selection stages, five studies were included, totaling 792 children of both sexes and aged between two and 11 years. Interventions offered 300–880 IU of vitamin D per day, for a period of 1.6–9 months, using fortified dairy products. In four of the five studies, there was an increase in the serum concentrations of 25(OH)D with the consumption of these foods; additionally, most children reached or maintained sufficiency status. Moreover, the consumption of vitamin D-fortified foods proved to be safe, with no concentrations of 25(OH)D > 250 nmol/L. Based on the above, the fortification of foods with vitamin D can help maintain or recover the nutritional status of this vitamin in children aged 2–11 years. However, it is necessary to perform additional randomized clinical trials in order to establish optimal doses of fortification, according to the peculiarities of each region.

A educação alimentar e nutricional é um fator determinante para a prevenção e controle das doenças crônicas não transmissíveis como o diabetes mellitus tipo 2. Assim, o objetivo deste estudo foi avaliar o efeito de ações de educação alimentar e nutricional na percepção e no conhecimento sobre a doença, seu tratamento e dificuldades enfrentadas por pessoas com diabetes mellitus tipo 2. Estudo longitudinal do tipo quanti-qualitativo, realizado com 10 adultos com diabetes mellitus tipo 2, atendidos pela Liga Acadêmica de Nutrição em Diabetes da Universidade Federal de Sergipe. Os indivíduos foram convidados a participar de ações de educação alimentar e nutricional realizadas semanalmente durante seis semanas. Os participantes foram entrevistados antes (T0) e após (T1) as ações a fim de investigar os conhecimentos obtidos. Utilizouse a entrevista semiestruturada com duas perguntas para obtenção dos discursos, a primeira relacionou-se com a percepção sobre a doença e tratamento, e a segunda com as dificuldades enfrentadas na busca da alimentação saudável. A análise foi realizada pela técnica de Análise de Conteúdo. Para a primeira pergunta emergiram discursos categorizados em significado emocional, fisiológico e tratamento, já para a segunda emergiram aspectos externos, internos e sem dificuldades. Após as ações, os discursos mostraram-se positivos quanto à adoção de uma alimentação saudável no tratamento. A intervenção permitiu que os indivíduos obtivessem maior conhecimento da doença e dos aspectos relacionados ao tratamento.
