Low to medium GI foods like Jerusalem Artichokes are digested slower and cause much less fluctuation in blood sugar levels. This helps makes controlling blood sugars a little easier.
When we eat foods high in carbohydrates causing our blood sugar levels to rise our pancreas secretes a hormone called insulin. Insulin causes the liver, muscles and fat cells to store this blood sugar as energy for later use. High blood sugar levels leave excess sugar in the blood which is stored as extra fat. If we don't burn off this energy we get increase in weight. As low GI foods curb food cravings by making you feel full for longer Jerusalem Artichokes can aid with weight loss.
