As if you needed another reason for that nightly glass of Cabernet. Oregon State University and Oklahoma State University recently teamed up to study the metabolic effects of chemicals in grape juice. They found that one compound, ellagic acid, dramatically slowed the growth of existing fat cells and the formation of new ones. It also increased the burning of fat in the liver. While it hasn’t been shown to specifically decrease bodyweight, a fatty liver can contribute to a flagging metabolism. Ellagic acid proved to impart a beneficial impact on blood-sugar levels as well. What’s more, you don’t have to quaff merlot to get a dose of the stuff. Ellagic acid is found in grapes and other dark red fruits such as raspberries, cranberries, blackberries, and pomegranate.
