Chef Bill talks about
Phytochemicals in our food and according to Wikipedia
Phytochemicals are chemical compounds that occur naturally in plants (phyto means "plant" in Greek). Some are responsible for color and other
organoleptic properties, such as the deep purple of blueberries and the smell of garlic. The term is generally used to refer to those chemicals that may have biological significance, for example
antioxidants, but are not established as essential nutrients. Scientists have estimated having the potential to affect diseases such as
cancer,
stroke or
metabolic syndrome.
