ABSTRACT High-fat diet-induced obesity is associated with metabolic disorders. The Brazil nut has bioactive substances and has been used to control the damage caused by obesity in several organs. The work intended to show the damage caused by high-fat diet in the bladder wall and if the Brazil nut oil added to the diet could ameliorate or reverse this effect. Sixty-day-old rats were divided into two groups: C (control, n = 30) and HF (high-fat, n = 30) diets. At 90 days, 10 animals of each group were sacrificed. The others were divided into 4 groups: C and HF (animals that maintained their previous diet, n = 10 for each group) and C / Bno and HF / Bno (animals whose control or high-fat diet was supplemented by Brazil nut oil, n = 10 for each group). Sacrifice occurred at 120 days, and the bladders were removed and analyzed. Epithelial height was increased in the HF compared to the C group. In contrast, the C / Bno had a lower epithelial height compared to the others. The percentage of collagen between the detrusor muscle fibers was significantly greater in C / Bno, HF and HF / Bno than in control group. The HF had a larger muscle fiber diameter than the C group, while the C / Bno presented lower values than the HF and HF / Bno groups. HF diets induced bladder wall damage. These changes in the rat's bladder wall were partially reversed by the Bno.

OBJETIVO: Este estudo tem como objetivo comparar o consumo alimentar durante a semana com o do final de semana de vinte crianças de uma creche filantrópica, com base na pirâmide alimentar de crianças brasileiras de dois e três anos, proposta por Philippi. MÉTODOS: A avaliação sociodemográfica foi realizada por meio das variáveis: renda mensal familiar, escolaridade, condições de moradia e saneamento básico. Para a avaliação dietética foram utilizados os métodos de pesagem direta de alimentos (na creche) e registro alimentar (na residência) após três meses de freqüência da criança na creche. Os alimentos e preparações consumidos pelas crianças durante a semana e no final de semana foram transformados em porções em função dos oito grupos de alimentos correspondentes, conforme recomendado por Philippi. Posteriormente, compararam-se as médias das porções consumidas no final de semana com o consumo semanal de cada grupo de alimentos, utilizando o teste "t" de Student para verificar significância estatística entre os grupos, considerando o nível de significância de 5%. RESULTADOS: Observou-se uma diferença significativa (p<0,05) entre a média de porções de carnes, leguminosas, legumes e frutas consumidos nos dois momentos avaliados. CONCLUSÃO: A dieta do final de semana é mais inadequada do que a dieta oferecida às crianças durante a semana.

OBJECTIVE: The objective of this study was to compare the food consumption during the week of twenty children at a nonprofit day care center, with that consumed at the weekend, based on the Brazilian Food Guide Pyramid for two to three year old children proposed by Philippi. METHODS: The social demographic evaluation was based on the following variables: income, educational level, housing and sanitation conditions. The food intake was measured by direct weighing of the food (in the day care center) and registry of the food consumed (at home), after three months attendance of the child at the day care center. The food and meals consumed by the children during the week and at the weekend were transformed into portions based on the eight corresponding food groups, according to Philippi. The average daily consumption of each food group, in portions, at the weekend, was then compared with that consumed on weekdays using the Student "t" test, considering a 5% significance level. RESULTS: A significant difference (p<0.05) was observed between the average number of portions of meat, legumes, vegetables and fruits consumed in the two periods evaluated. CONCLUSION: The results suggest inadequacy of the diet consumed by the children at the weekend when compared to that consumed during the week.
