Let me add to Starchild's recommendation that the more whole fresh fruit and vegetables you eat, the greater your probability of avoiding cancer, heart disease, diabetes, arthritis, and osteoporosis.
Don't take our word for it and certainly don't take the media seriously. Instead, read the original research yourself with a critical eye. (If you're interested my article, "Pitfalls in Interpreting Nutritional Studies," I'd be pleased to email it to you.)
Best, Michael
