Brief Summary
Does the consumption of various combinations of mono and disaccharides (lactose, sucrose and fructose) and protein isolates (whey or soy) result in altered substrate absorption, substrate oxidation, and glucose regulation? This proposed research will provide data to determine the relative contribution of source of protein (whey vs soy) and carbohydrate (mono- and disaccharides) on the observed effects of dairy products on absorption, substrate oxidation and glucoregulation mechanisms that affect body composition.
