What are the best foods to improve cholesterol?

Foods containing soluble fiber, such as oatmeal, kidney beans, apples, pears and barley, lower levels of unhealthy low-density lipoprotein, as detailed by Mayo Clinic. Prunes are also good sources of soluble fiber.

Eating fish and other foods containing omega-3 fatty acids also lowers levels of dangerous cholesterol, as Mayo Clinic explains. Fish particularly high in omega-3 fatty acids are mackerel, lake trout, herring, sardines and albacore tuna. Baking or grilling the fish prevents adding unwanted fats.

Many nuts contain polyunsaturated fatty acids, which aid in vascular health. Almonds, hazelnuts, peanuts and pecans can lower cholesterol levels, according to Mayo Clinic.
