Description
Summary:The aims of the study were to evaluate iron availability in a typical diet consumed in self service restaurants in the State of Sao Paulo and to verify if the addition of different proportions of cabbage in the diet increases dietary iron and iron availability. The centesimal composition, fiber, iron and in vitro iron dialysis of diet or mixture with raw and cooked cabbage in different portions (0.5, 1.0, 1.5 and 2.0) were measured. The results of the centesimal composition were distinct for each treatment, with emphasis for fibers amount which showed higher levels (p ≤ 0.05) with the addition of raw cabbage compared to the addition of cooked cabbage. There were significant increases in lipids, protein and ashes amount with the increase of the portions of cabbage added. For iron amount it was observed that the treatment with raw cabbage presented the largest amount and the largest iron availability. The comparison between raw and cooked cabbage showed bigger availability to raw cabbage too. The diet without cabbage presented the iron availability of 0.18% while with the addition of raw cabbage the iron availability was 0.30%. We concluded that the addition of cabbage feeding back-wards benefit with increased iron mineral and its availability. KEYWORDS: Dialysis; iron; centesimal composition; fiber; cabbage. O objetivo desse trabalho foi avaliar a disponibilidade de ferro em uma dieta tipica consumida em restaurantes tipo self-service no Estado de Sao Paulo e verificar se a adicao de porcoes de couve manteiga nesta dieta aumenta a disponibilidade de ferro dietetico. Foi determinada a composicao centesimal, teor de fibras, ferro e dialise de ferro in vitro da dieta e suas misturas com couve crua ou cozida em diferentes porcoes (0,5, 1,0, 1,5 e 2,0). Os resultados da composicao centesimal evidenciaram diferencas entre tratamentos, com enfase para os teores de fibras com a adicao de couve crua (p [menor que o igual a] 0,05), sendo maior em relacao a adicao de couve cozida. Ocorreram aumentos significativos dos teores de lipidios, proteina e cinzas, com o aumento de porcoes de couve. O teor e a disponibilidade de ferro no tratamento com couve crua se apresentaram superiores. A comparacao entre couve crua e cozida tambem demonstrou maior disponibilidade de ferro para couve crua. A dieta sem adicao de couve apresentou disponibilidade de 0,18% para ferro enquanto que com a adicao de couve crua apresentou disponibilidade de 0,30%. Conclui-se que a introducao de couve manteiga na dieta pode trazer beneficios como aumento do teor e da disponibilidade de ferro. PALAVRAS-CHAVE: Dialise; ferro; composicao centesimal; fibras; couve manteiga.
