The physical breakdown of food is a physiological process known as digestion. To benefit your body, the foods you eat must be broken down so the nutrients they contain can move from your gut through the cells of your intestines and into your bloodstream.
As you continue chewing, your mouthful becomes sweet if you're eating carbohydrates because enzymes in your saliva begin to break complex carbs down into simple sugars. Later, in the stomach and intestines, proteins and fats are also broken down by enzymes.hemical digestion refers to the work performed by enzymes throughout your digestive tract, which break the bonds that hold molecules together so that proteins, carbohydrates and fats are split into single molecules.
