Digestion, you also learnt, begins in the mouth, when we chew and swallow, and is completed in the small intestine. The chemical process varies somewhat for different kinds of foodlnutrients i.e. for carbohydrates, proteins, fats etc. In this section, we shall learn about the chemical process involved during the digestion of these nutrients in the body.
