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.
The study, to be published in the June 29 issue of Journal of Agricultural and Food Chemistry, compared apple varieties popular in Canada, some of which are available only regionally in the United States.
Red Delicious, which account for 27 percent of U.S. apple production, has more than six times the antioxidants as the bottom-ranked Empire variety. Northern Spy was No. 2, followed by Cortland, Ida Red, Golden Delicious, McIntosh and Mutsu.
And in every variety tested, the skins of the apples contained substantially higher levels of antioxidants than the flesh.
Though apples have significantly lower concentrations of antioxidants than other fruits, especially many berries, researchers say year-round availability and greater popularity might make them a better source for many people.
