Dr.Perricone has written many articles about watercress as he claims, it "continues to impress as a superfood." Here's a favorite article from the good doctor: http://www.dailyperricone.com/2011/02/the-wonders-of-watercress/
A reader asked Dr.Perricone how much watercress should we eat?
His reply, "shoot for at least one serving per day."
I couldn't agree more.
