You've probably heard much talk in recent years about the benefits of adding antioxidant-rich foods to your diet. In the course of normal living, millions of chemical processes occur in our bodies each day.

Phytochemicals are chemicals synthesized from plants. When phytochemicals are present in food, they can have profound health benefits for the consumer.
