(UPI)--Ohio State University researchers want the government to create a new food group--foods colored red, orange-yellow, green and purple-blue.

They think giving such foods special emphasis would encourage consumers to eat more fruits and vegetables. And, maybe, even learn the health benefits of eating such colorful foods.

For example, research has shown that blueberries have antioxidants and other compounds that help fight off various cancers, are high in fiber, may help reverse problems associated with aging and also contain concentrated tannins--compounds that have been found to prevent urinary infections and are not found in such fruits as apples and oranges.
