High-fiber foods positively impact cholesterol levels by promoting the excretion of cholesterol and enhancing the metabolism of bile acids. Soluble fiber, found in foods like oats, beans, and fruits, binds to cholesterol in the digestive system, which helps reduce low-density lipoprotein (LDL) levels. Incorporating a variety of high-fiber foods into the diet can also help manage weight and promote heart health. Additionally, fiber-rich diets encourage regular digestion and may contribute to lower blood sugar levels, creating overall benefits for metabolic health.
