[Effect of different starch and dietary fiber of preparations levels on immediate and subsequent consumption in preschool children 24-48 months of age].
The aim of this study was to examine in preschool children the effects of different levels of starch and dietary fiber of a meal time on the immediate food and energy intake (in the same meal time) and in the following meal (subsequent intake). The study was performed in 50 children both genders, with ages ranging from 24 to 48 months, with normal nutritional status (weight/height index) according to the NCHS standards. The food intake was determined by differential weighing and energy intake was calculated from proximal analysis. In the lunch, several meals were offered differing in their starch and dietary fiber but with similar energy density (1 kcal/g). The results of the immediate consumption demonstrated that the two dietary treatments were significantly and the effect was a lower consumption of food and energy, while the starch an dietary lower consumption of food and energy, while the starch an dietary fiber levels increased. It was observed and interaction between both variables. The subsequent food and energy intake showed the same tendency that was observed in the immediate consumption but there was not an interaction between both variables. The lowest value of intake was showed by the children who consumed the meal with the highest level of starch and dietary fiber. When results of both meal times were combined, the same effects were demonstrated. The findings described have been not reported by others authors. A probable explanation for these results are the lower gastric emptying caused bu high levels of starch and dietary fiber and in the specific case of starch by its glycemic index.(ABSTRACT TRUNCATED AT 250 WORDS)
