RALEIGH, N.C. — If you look at just one color, a rainbow is not nearly as breathtaking, but when you take in all the colors, you see it is a brillant beauty. That same spectrum needs to be on your plate too.

Most people have what is called a brown and white diet.

"They know the starches, the white foods, the cream-color foods, the potatoes, breads, starches," registered dietitian Gail Frank said. "Healthy eating is bringing the rainbow into eating."

When you add color in the form of fruits and vegetables, you not only get variety, but you also get a healthy boost. The colorful foods are packed with antioxidants, which help prevent certain cancers and heart disease.

"They have vitamins A, C and E. These are the most antioxidant protective," Frank said.

If you have a colorless diet, strive to eat five servings of colorful fruits and vegetables a day. While that sounds like a lot, try adding blueberries or another fruit to your cereal at breakfast or a vegetable or two to your lunch and dinner.
