After a meal, the carbohydrates, fats, and proteins in food are digested in the intestinal tract, then absorbed into the bloodstream. Blood sugar levels rise after meals, but the sugar will not do any good unless it gets into the body’s cells. Insulin, produced by the pancreas, is the hormone that opens the door, allowing glucose to enter cells.
