What are antioxidants?They are any compounds that protect the body from adverse biological reactions involving oxygen.This may sound strange,because we know that oxygen is necessary for the body to function,without oxygen,our cells die within minutes.A great irony of nature is that the body's natural metabolism involving oxygen also produces a host of toxic compounds called 'free radical'.These compounds can harm body cells by altering molecules of protein and fat,and by damaging DNA.Antioxidants counteract,or neutralize,the harmful effects of free radicals.Through enormous research over the past decade,a huge array of antioxidant phytochemicals found in the plant kingdom have been identified.The important ones that have been studied for their ability to fight cancer are lycopene,beta-carotene,curcumin,resveratrol and many different kinds of polyphenols,including the class flavonoid.Because these phytochemicals are in the fruits,vegetables,beans,and grains you eat,it is fairly easy to include them in your diet.
