It's true -- eating oatmeal can lower your cholesterol. It has soluble fiber, which brings down "bad" LDL cholesterol. Adding just 5-10 grams of soluble fiber a day -- that's one or two large apples with skin -- can lower LDL by 5%.
You'll also find soluble fiber in many fruits and veggies, nuts, and dried beans, such as kidney, pinto, and black beans. To get the greatest health boost from fiber, aim for 10 to 25 grams daily. Lentil soup is a tasty way to get 9 grams.
