Whole foods: Not just a grocery store

Eating a whole-foods diet has been shown to reduce the risk of many diseases and early aging. Interestingly, research has shown whole foods have more of a beneficial effect on disease compared to individual vitamin and mineral supplements. For example, a study examining beta-carotene showed that people eating fruits and vegetables high in beta-carotene had a lower risk of lung cancer than those who were supplemented with just beta-carotene.
