  2. Digestion Can Be a Mouthful! • Your digestive system is highly specialized for physically and chemically breaking down foods to obtain nutrients. Both of these processes begin in the mouth. • Starch (a carbohydrate) is an important food molecule found in many plants and is a major energy source in most human diets. • Lugol’s iodine stain can be used to detect the presence of starch.
