Which dietary modification is recommended to help lower cholesterol levels?

Increased fiber intake is recommended to help lower cholesterol levels primarily because soluble fiber can directly influence cholesterol metabolism. Soluble fiber binds to cholesterol in the digestive system, preventing its absorption into the bloodstream. Foods rich in soluble fiber include oats, beans, lentils, fruits (such as apples and citrus), and vegetables. By incorporating these foods into the diet, individuals can see a reduction in low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol.

Moreover, a diet high in fiber supports overall heart health by promoting healthy digestion and contributing to weight management, both of which can play a role in cholesterol levels. In contrast to this beneficial modification, approaches such as increasing saturated fat intake or decreasing fruit and vegetable servings can negatively impact cholesterol levels and overall cardiovascular health. Reducing water consumption does not have a direct relationship with cholesterol management and is not a recommended dietary change for this purpose.
