Rule # 25 Eat your colors

The idea that a healthy plate of food will feature several different colors is a good example of an old wives' tale about food that turns out to be good science too. The colors of many vegetables reflect the different antioxidant phytochemicals they contain - anthocyanins, polyphenols, flavonoids, carotenoids. Many of these chemicals help protect against chronic diseases, but each in a slightly different way, so the best protection comes from a diet containing as many different phytochemicals as possible.
