The correct answer is...

Dietary fiber, especially soluble fiber, plays an important role in managing cholesterol levels. Soluble fiber binds to cholesterol in the digestive system and helps remove it from the body through waste. This process reduces the amount of cholesterol that gets absorbed into the bloodstream. Foods rich in soluble fiber, like oats, beans, lentils, fruits, and vegetables, can significantly lower LDL ("bad") cholesterol levels, supporting overall heart health. Regular intake of fiber is thus a key strategy for maintaining healthy cholesterol levels.
