antioxidants are produced by the body and some by plants, and so they can be derived from the diet. Their job is to combat free radicals – highly reactive molecules formed as a natural by-product of cellular activity. Free radicals are also created by exposure to cigarette smoke, strong sunlight, and breathing in pollution.
These aggressive chemicals present a constant threat to cells and DNA. We know they can lead to cell damage, cancer, diabetes and cardiovascular problems. Free radicals have also been implicated in everything from strokes to Parkinson’s and Alzheimer’s.
Antioxidants stop the chain reactions triggered by free radicals that can damage and destroy cells. So it may seem entirely reasonable that it would be a good thing to eat and drink more antioxidants to boost the supply – or even rub them into your skin
