Vegetarians tend to have lower cholesterol and heart disease rates due to their high fiber intake from plant foods. Soluble fiber, especially pectin found in apples, can lower LDL cholesterol by binding to and removing bile acids from the intestines. Consuming 15g of soluble fiber daily can lower cholesterol by 5-10%. Pectin also helps control appetite and weight by slowing digestion. High-fiber foods are often low in saturated fat, cholesterol and calories, though you need to watch out for high-fat toppings.
