Dietary components like fiber and complex carbohydrates are essential for regulating blood sugar levels. Specifically, fiber slows the absorption of glucose in the bloodstream, preventing spikes after meals. Foods high in fiber include fruits, vegetables, whole grains, and legumes, which help maintain stable blood sugar levels while providing other important nutrients. This balance is crucial for individuals with diabetes or those at risk of developing the condition. Incorporating fiber into the diet supports overall metabolic health and reduces the risk of insulin resistance.
