Your GI, or gastrointestinal, tract breaks down foods. The make-up of the food you ingest will determine how it's broken down. Your mouth mechanically (chewing) breaks down all food and chemically breaks down carbohydrates. Your stomach breaks down proteins and fats. Your small intestine breaks down everything else via pancreatic acids and enzymes. Majority of carbohydrates break down in the small intestine.
