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.
GIP   Well, Insulin is a hormone that lowers the blood sugar level. Normally, the Hypothalamus (in the brain) sends messages to the Pituitary Gland (also in brain) to releaâ¦se a hormone that tells a gland to release a certain hormone, but that is NOT the case with Insulin (and glucagon).   The pancreas can detect blood glucose levels.
