title: [Chemical and nutritional assessment of a soybean and cereal mixture for adults].
abstract: Legume seeds and fibre rich plant foods usually improve aspects of human diabetes control as they are potential sources of "delayed release" carbohydrates. A regional bakery mixture of soybean and cereals, interesting for its palatability and high content in non starch polysaccharides was chemically and nutritionally evaluated. Comparisons were made with the usual commercial laboratory chow and with a cafeteria mixture. Each one of the three diets was offered ad libitum to adult rats of line IIMb/Fm beta (beta), affected by obesity, hypertriglyceridemia and glucose intolerance or diabetes. Treatments lasted three months and were performed on two groups of male rats: (a) From 100 days old growing significantly. (b) From 200 days old. Meals had similar carbohydrate and calorie contents but acid followed by enzymatica hydrolysis was required to free monosaccharides from the soybean mixture. Cafeteria mixture lacked in fibre, was rich in saturated fats and sodium, and it caused hyperphagia. Each group of rats showed similar food intakes in both ages although weight gain was significantly higher in the younger animals. In the latter, values of glycemic response showed no difference between diets. Cafeteria mixture caused significant hyperglycemia to the elder rats, while the soybean bakery mixture produced a remarkably lower glycemic response; in one case it was even lower than the one produced by the commercial chow. Differential response showed more clearly with age. The results of the feces analysis demonstrated an increased proportion of fecal water for the bakery mixture group, probably due to the amount of undigestible fibre, inducing beneficial effects on large bowel functionality.
