Fruits and vegetables contain soluble and insoluble fiber in varying proportions. When you eat soluble fiber, it absorbs water to form a gel-like mass, which helps you feel full and provides other health benefits. It prevents a surge in blood sugar after you eat by slowing down the absorption of carbohydrates.
If the blood glucose level falls to dangerous levels (as in very heavy exercise or lack of food for extended periods), the Alpha cells of the pancreas release glucagon, a hormone whose effects on liver cells act to increase blood glucose levels.
The main hormones released by the pancreas are insulin and glucagon. These hormones help to regulate the amount of sugar found in the blood and the bodyâs cells. The body's cells need energy to function. The most readily available form of energy is glucose, a type of sugar.
