Blueberries

Blueberries have more antioxidants—those magical molecules that can help prevent a host of maladies than 40 other common fruits and vegetables tested.

The antioxidant plant pigments that make blueberries blue guard against heart disease, cancer and age-related blindness and memory loss. They’re also tops when it comes to preventing urinary tract infections, thanks to antioxidant epicatechins, which keep bacteria from sticking to bladder walls.

How much? 1/2 cup (125 mL) of blueberries equals one fruit and vegetable serving per day.

Tip: Sprinkle blueberries on your pancakes at the last minute—cooking the berries destroys valuable vitamin C.
