Interpretive Summary: Legumes such as soy are known to have health benefits. We evaluated legumes commonly consumed in the US, black beans, pinto beans and white beans, for their hypocholesterolemic properties. Because uncooked legumes have antinutritive properties the beans were cooked by a continuous extrusion process at high temperature for short times. The beans were fed to hamsters on high fat, hypercholesterolemic diets. The beans decreased liver cholesterol and increased cholesterol and bile acid excretion in feces. Animals on the black bean diet had weight gains similar to animals on a low fat reference diet.

Technical Abstract: Extruded black, pinto and white beans were fed to male Syrian hamsters for 3 weeks to determine the efficiency and effectiveness of extruder processing to eliminate heat-labile antinutrients and also evaluate the hypolipidemic and anti-obesity properties of the extruded legumes. Hamsters fed a high fat diet containing 40% extruded black beans gained the same amount of weight as animals on a low-fat chow diet (based on AIN-93G). The results show that extrusion efficiently and economically reduces anti-nutritive factors that inhibit the digestion and absorption of proteins and carbohydrates. Legume feeding resulted in lower fecal dry weight compared to controls fed cellulose, suggesting that legume dietary fibers are fermentable and may contribute to colonic health. Liver cholesterol was reduced and bile acid and cholesterol excretion increased by legume fed animals.
