Goji Berries

"These raisin-size fruits are chewy and taste like a cross between a cranberry and a cherry. More important, these potent berries have been used as a medicinal food in Tibet for over 1,700 years.

Why they're healthy: Goji berries have one of the highest ORAC ratings—a method of gauging antioxidant power—of any fruit, according to Tufts University researchers. And although modern scientists began to study this ancient berry only recently, they've found that the sugars that make goji berries sweet reduce insulin resistance—a risk factor of diabetes—in rats."*

How to eat them: Mix dried or fresh goji berries with a cup of plain yogurt, sprinkle them on your oatmeal or cold cereal, or enjoy a handful by themselves.
