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.
