Blue foods ‘filled to the brim’ with nutrients for good health

Blue (and purple) foods, such as this blue corn, are not only lovely to look at, they are also often nutritionally beneficial. (Dreamstime/TNS)

In the quest for optimal nutrition, we’ve been told to try to “eat the rainbow.”

That means you should stock your plate with a wide range of fruits and vegetables representing the hues found in the rainbow. The more brightly vibrant and diversely colorful produce, the more likely it is that this diet is filled to the brim with vitamins, minerals and health-promoting plant compounds.
