The USDA recently ranked wild blueberries the No.1 antioxidant fruit in a study that included over 100 fruits, vegetables, spices and nuts. And growing scientific evidence suggests a diet high in antioxidants may help reduce the risk of heart disease, age related memory loss, even cancer.
At the University of Illinois, cancer researcher
May Ann Smith, Ph.D. and associates showed that proanthocyanidin
in wild blueberries inhibits an enzyme involved in the promotion
stage of cancer.
Smith applied extracts from wild blueberries, cultivated
blueberries and bilberries (the European cousin of the wild
blueberry) to living cells at various stages in cancer
development. Wild blueberries exhibited the greatest anticancer
activity of all the berries.
USDA scientists have recently discovered that blueberries and
cranberries contain significant levels of resveratrol, a natural
compound that has been found to have anti-cancer qualities.
