Power Berries

For decades, many state governments held a ban on cultivating black currants due to concerns that the plant could spread a destructive tree fungus. Today, growing these tangy berries is once again legal in most of the country. With more vitamin c than oranges and antioxidant levels that rival those of blueberries, this nutrition hero delivers healthy doses of potassium, vitamin B6, and soluble fiber.

Look for fresh berries at the farmers' markets in late summer, or frozen berries year-round. You can also pick up black currant juice, soda or preserves to get your daily dose.

Fruit Improves Brain Function
