How it works? How carbohydrates bring you energy?

So, when you eat a food containing carbohydrates, your digestive system breaks down digestible parts into sugar. It then enters the blood. As blood sugar levels rise, special cells in the pancreas stir up more and more insulin, a hormone that signals cells to absorb blood sugar for energy or storage (uh-oh - something to watch out!). As cells clean blood sugar, its levels in the bloodstream start to fall. That's when other cells in the pancreas start making glucagon, a hormone that tells the liver to start releasing stored sugar. This relationship of insulin and glucagon ensure that body cells, and especially brain ones, have a secure supply of blood sugar.

Healthy diet is long happy life!
