Choose breads made from 100 percent whole grains instead of breads made from refined white flour. 2. Select brown rice instead of white rice. 3. Trade sugar-sweetened cereals for whole-grain cereals, such as whole-wheat bran flakes, shredded wheat or oatmeal.   Need practical advice on diet and exercise?
