Chapter 11, Problem 1BCTQ
The American Heart Association and other health organizations have concluded that consumers should get their antioxidants from foods rather than supplements. They add that taking supplements may even be harmful. Supplement manufacturers claim that such statements are unfair and that their natural botanical extracts provide numerous health benefits. In fact, some suggest that beneficial effects can only be achieved by taking high-dose supplements. Given that there are currently no DRI defining the kinds of antioxidants or the daily quantities needed, how might you ensure a healthy intake of antioxidants? If you decide to take an antioxidant supplement, how might you research the product to determine its safety and effectiveness?
