Fiber plays a crucial role in regulating blood sugar levels by slowing carbohydrate absorption in the bloodstream. High-fiber foods help maintain stable blood glucose levels, reducing the risk of insulin resistance and diabetes. Soluble fiber, in particular, can lower cholesterol levels and improve overall heart health. Incorporating fiber-rich foods like fruits, vegetables, legumes, and whole grains into the diet can support digestive health, contribute to satiety, and promote balanced blood sugar control, essential for maintaining energy levels.
