Blueberries

Why eat blueberries? Blueberries are a rich source of plant compounds (phytonutrients). Phytonutrients in blueberries may prevent urinary tract infections by increasing the acidity of urine, which helps destroy any bacteria. Blueberries may also improve short-term memory and promote healthy aging.

Blueberries are also a low-calorie source of fiber and vitamin C — 1 cup of fresh blueberries has 83 calories, 3.5 grams of fiber and 14 milligrams of vitamin C.
