Phytonutrients

Plant foods contain thousands of natural chemicals. These are called phytonutrients or phytochemicals."Phyto" refers to the Greek word for plant. These chemicals help protect plants from germs, fungi, bugs, and other threats.

Fruits and vegetables contain phytonutrients. Other plant-based foods also contain phytonutrients, such as:

  • Whole grains
  • Nuts
  • Beans
  • Tea
