  • Definitions you may need to know
  • Free radicals- are byproducts of metabolism. They

    them.
  • Connected with the development of 50 diseases
    including heart disease and cancer.

6
Phytochemical Terminology
  • What are antioxidants?
  • Capable of stabilizing or deactivating free
    radicals before they attack cells.
  • Chemoprevention- using one or several compounds
    to prevent, stop or reverse the development of
    cancer.

7
Phytochemical Terminology
  • Designer Food- Processed foods that are
    supplemented with food ingredients naturally rich
    in disease-preventing substances.
  • Functional Food- any modified food or food
    ingredient that may provide a health benefit
    beyond the traditional nutrients it contains.

8
Phytochemical Terminology
  • Nutraceutical - specific chemical compounds in
    food, including vitamins and additives, that may
