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 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. You can find them at specialty supermarkets or at gojiberries.us.
