Fiber plays a crucial role in managing cholesterol levels within the body. Soluble fiber, found in foods like oats, beans, and fruits, binds to cholesterol and assists in its excretion from the body. This process helps lower the total cholesterol and low-density lipoprotein (LDL) levels, often referred to as "bad" cholesterol. In contrast, insoluble fiber improves digestive health but does not directly impact cholesterol levels. Including a variety of fiber sources in the diet is essential for heart health and can significantly contribute to overall well-being.
