Why: The soluble fiber in oatmeal has been proven to lower levels
of the bad cholesterol LDL by slowing its absorption into the bloodstream.
Look for: Steel-cut oats for the most fiber. Steer clear of
most fast-food options because of their high sugar or calorie content. Try eating
five to 10 grams of soluble fiber a day to get this heart-healthy
benefit; a cup and a half of oatmeal is the equivalent of about six grams
of fiber.
