Digestive Enzymes. No matter what specific foods we eat, our diets are composed of protein, fat and carbohydrates. Digestive enzymes break down protein, carbohydrates and fats into progressively smaller components. Enzyme supplements normally contain amylase, protease and lipase. Cellulase, lactase, malt diastase, invertase (sucrase), glucoamylase, bromelain and papain may also be included in digestive products.
