Phytochemicals give color, flavor and smell to plants.
All plants contain phytochemicals but the exact compounds may not yet be identified in each plant. While all fruits and vegetables contain phytochemicals, they will not have the same kind or amount. The research on phytochemicals and their importance in health is still emerging. This increases the importance of eating a variety of fruits and vegetables every day to take advantage of the known nutritional components plus the benefits of phytochemicals.
