These whole-grains are among the best sources of soluble fibre, which blocks your body from absorbing cholesterol and helps lower LDL cholesterol.
The soluble fibre that is found in oats and barley, called beta-glucan is especially powerful. Eating oats with at least 3 grams of soluble fibre every day, for instance, can lower LDL and total cholesterol by up to ten percent.
Try eating oatmeal for breakfast and sprinkle oat bran into yogurt. Use cooked barley just as you would rice — in soups, in salads, or as a nutritious side dish mixed with vegetables.
