HEALTH TIP OF THE WEEK
Whole grains for a healthy heart
Whole grains are good sources of fiber. Better yet, nutrients found in whole grains help promote heart health. To increase the amount of whole grains in your diet, make simple substitutions: 1. Choose breads made from 100 percent whole grain instead of those made from refined white flour. 2. Choose whole-wheat pasta over regular pasta. 3. Select brown rice instead of white rice. 4. Trade sugar-sweetened cereals for high-fiber cereals, such as bran flakes or shredded wheat. 5. Bake with whole-wheat flour rather than white flour.
