Antioxidants neutralize free radicals either by providing the extra electron needed to make the pair, or by breaking down the free radical molecule to render it harmless.
“Antioxidants stop the chain reaction of free radical formation and benefit our health by boosting our immune system ,” explains Prabhu. Because antioxidants are used up in the process of free radical neutralization, a diet rich in antioxidants is essential to ensure a constant supply.
Research has shown that antioxidants can have an important impact on serious diseases. In one recent study, the addition of a polyphenol-rich blueberry gel to the diet of oral cancer patients prevented recurrence of the cancer. Another experiment demonstrated that increased levels of selenium in the diets of a group of HIV-positive patients significantly delayed progression of the disease.
