Polyphenols can help prevent and manage type 2 diabtetes

The benefits of tea are clear. But besides tea, a number of foods high in polyphenols also can help prevent and manage type 2 diabetes. “The fruits highest in polyphenols are berries, grapes, apples, and pomegranates -- because of their rich color,” Steinbaum says. Broccoli, onions, garlic, tomatoes, eggplant, and spinach are also good sources, as are cranberries, blood oranges, blackberries, blueberries, raspberries, strawberries, rhubarb, lemons, limes, and kiwis. “We know red wine contains resveratrol, which is a polyphenol -- the highest concentration is in Bordeaux,” Steinbaum says.
