Carbohydrates, lipids, and proteins are considered macronutrients and serve as a source of

Carbohydrates and Blood Sugar – The Nutrition Source

When people eat a food containing carbohydrates, the digestive system breaks down the digestible ones into sugar, which enters the blood. As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage. As cells absorb blood sugar, levels in the bloodstream begin to fall.
