More isn’t always better. Taking too many antioxidants in the form of supplements, could pose a health risk. Researchers believe that if you are taking too many vitamins you may be predisposing your cells to developing cancer. Many people feel that if taking some vitamins is good, taking more is even better—this is not the case.
As far as antioxidant rich food goes, you don’t have to worry. There is still much benefit to ingesting antioxidant-rich foods. Even when eaten in large quantities foods that are rich in antioxidants do not put you at risk.
