The prevalence of obesity and its associated health problems is rising to epidemic proportions throughout the world. Soy hulls, an industrial waste from oil extraction, contain a high proportion of fiber--soluble and insoluble--and may be a potential ingredient of functional foods for the prevention of obesity. However, crude soybeans, as do all legumes, present challenges to their use because of intensive antitrypsin and antichimotrypsin activity that impairs normal growth in humans and other mammals, requiring inactivation. To evaluate possible antinutritional effects of soybean hulls, diets with 10 percent fiber from soybean hulls or cellulose were offered to weanling IIMb/Beta obese rats during their prepubertal timeframe. The fact that no significant differences were found in growth, blood parameters nor in fat depots' weight and lipid content plus the proven beneficial effects on obese adult rats suggest that soy hulls may be a useful ingredient of functional foods for the prevention and treatment of human obesity.
肥胖及其相关健康问题在全球范围内正呈流行趋势。大豆皮是油脂提取过程中的一种工业废料，含有高比例的纤维（包括可溶和不可溶纤维），可能是预防肥胖的功能性食品的潜在成分。然而，与所有豆类一样，粗大豆因其强烈的抗胰蛋白酶和抗胰凝乳蛋白酶活性而在使用上存在挑战，这种活性会损害人类和其他哺乳动物的正常生长，需要将其灭活。为了评估大豆皮可能存在的抗营养作用，在断奶的IIMb/Beta肥胖大鼠青春期前阶段，给它们提供了含有10%大豆皮纤维或纤维素的日粮。在生长、血液参数、脂肪储存重量和脂质含量方面未发现显著差异，以及对成年肥胖大鼠已证实的有益作用，表明大豆皮可能是预防和治疗人类肥胖的功能性食品的有用成分。
