Key Term: Phytochemical
Naturally occurring component in plants that appears to have beneficial effects upon human health (beyond nutritional demands) (Levetin & McMahon, 1996).
Many plants contain incredible phytochemicals which have been proven to help provide protection against cancer, hypertension, heart disease, arthritis and various other conditions and diseases associated with aging (Levetin & McMahon, 1996). This is part of the reason why the high consumption of Fruits and Veggies as well as Whole Grains is so greatly encouraged. According to the Canada Food Guide, adults should eat 7-10 and 6-8 servings of Fruits/Vegetables and Whole Grains, respectively.
