ABSTRACT Aims:To nutritionally analyze diets published in a women's magazine and compare them with current dietary recommendations for macronutrient and micronutrient intake by adult women. Methods: Twenty-four issues published in 2013 and 2014 by women's magazine with the largest circulation in that period were selected, and the weight-loss diets therein were assessed. The nutritional composition was calculated by the Avanutri ® software and compared with the current recommendations from the Institute of Medicine for macronutrients and micronutrients. The diets were divided into two groups: large caloric restriction (≤ 1,100 kcal) and slight caloric restriction (> 1,100 kcal).Results: Twenty diets were analyzed, with an average caloric value of 1,227.83±261.54 kcal. All diets were deficient in vitamin D (mean of 2.09±1.16, folic acid (mean of 109.26±41.19), iron (mean of 11.35±3.06), calcium (mean of 532.23±133.56), and zinc (mean of 4.23±2.11). When both groups were compared, diets with large caloric restriction had lower concentrations of vitamin C (p=0.011), iron (p=0.051), calcium (p=0.022), and zinc (p=0.033). Most diets contained the recommended amount of macronutrients, but all of them were lacking in fibers. Most diets with inappropriate amounts of macronutrients and micronutrients were in the large caloric restriction group. Conclusions: Most diets had a deficient supply of energy and nutrients, especially vitamins and minerals that are important for women of childbearing age. Diets with large caloric restriction often contained inappropriate nutritional values. This result reinforces the importance that diets be individualized and monitored by a qualified professional.

O objetivo do estudo foi avaliar a escolha alimentar de usuários universitários beneficiados com o auxílio alimentação. Foi realizado um estudo transversal em uma Unidade Produtora de Refeição de um restaurante universitário da cidade de Guarapuava-PR, com 175 participantes. Foi avaliado o Índice de Massa Corporal (IMC) auto referido e a avaliação da escolha alimentar deu-se por meio de um cartão e do registro fotográfico dos pratos, para verificar a presença dos grupos de alimentos no almoço de cinco dias. De acordo com o IMC, a maior parte dos participantes encontrava-se em estado de eutrofia. Em relação a escolha alimentar, 96,5% (n=169) dos participantes escolheram alimentos do grupo dos cereais, raízes e tubérculos nos cinco dias avaliados, 60,5% (n=106) escolheram alimentos do grupo das leguminosas (feijão) todos os dias da semana e 27,4% (n=48) dos  participantes escolheram esse alimento 3 a 4 vezes na semana, já a escolha de alimentos do grupo das hortaliças durante cinco dias da semana foi de 90,2% (n=158), do grupo das carnes 84,5% (n=148) dos participantes escolheram alimentos desse grupo todos os dias da semana e 11,4% (n=20) de 3 a 4 vezes. Em relação ao grupo de doces e açúcares aqui representado pelas sobremesas, 72,5% (n=127) dos participantes não escolheram alimentos desse grupo e 20,5% (n=36) escolheram 1 a 2 vezes na semana. A maioria dos participantes realizam escolhas saudáveis, o que mostra que o auxílio alimentação tem sido um ponto positivo para a alimentação dos comensais beneficiados.

Different molecules have been tested as analog receptors due to their capacity to bind bacteria and prevent cell adhesion. By using in vitro assays, the present study characterized the aqueous and alkaline extracts from microalgae Pavlova lutheri and Pavlova gyrans and evaluated the capacity of these extracts to adhere to enterobacteria (Salmonella Typhimurium). The aqueous and alkaline extracts of both species were fractionated via freeze-thawing, giving rise to soluble and insoluble (precipitate) fractions in cold water. The obtained fractions were studied using thermogravimetric, methylation analyses, and using 1D and 2D NMR techniques. The cold-water-soluble fractions obtained from the aqueous extracts were mainly composed of highly branched (1→3),(1→6)-β-glucans, whereas the cold-water-precipitate fractions were constituted by (1→3)-β-glucans. The alkaline extract fractions showed similar compositions with a high protein content, and the presence of glycosides (sulfoquinovosylglycerol (SQG), digalactosylglycerol (DGG)), and free fatty acids. The linear (1→3)-β-glucans and the alkaline extract fractions showed an adhesion capacity toward Salmonella. The chemical composition of the active fractions suggested that the presence of three-linked β-glucose units, as well as microalgal proteins and glycosides, could be important in the adhesion process. Therefore, these microalgal species possess a high potential to serve as a source of anti-adhesive compounds.
