A Canadian government study that measured the levels of antioxidants in eight varieties of apples found that Red Delicious contain the highest concentrations of the health enhancing chemicals.
And to get the most bang for your bite, be sure to eat the peel.
The skin of Red Delicious apples — the most common variety grown in the United States — contains over six times more antioxidant activity than the flesh, according to researchers at Agriculture and Agri-Food Canada.
But don't swear off other varieties just yet.
Though antioxidants are believed to help ward off certain diseases, more research is needed to determine whether quantity alone counts. The study did not consider whether antioxidants in some apples may be better absorbed than others.
Until that is known, food scientist Rong Tsao says his study — which also identified the chemicals responsible for antioxidant activity in apples — probably is most useful to horticulturists breeding new, antioxidant-rich varieties.
The information also could lead to the development of techniques for harvesting antioxidants from the waste products of the apple processing industry, the bulk of which is peel, Tsao said during a recent telephone interview.
