2. Blueberries’ Nutrient Content
Blueberries are also a good source of vitamins, minerals, dietary fiber, and are very low in fat and sodium. In just half a cup of blueberries you get 2 grams of fiber, equal to a slice of whole grain bread. Nutrient content of blueberries is a dieter’s dream come true. According to Health Magazine, blueberries are a particularly rich source of anthocyanins (also contained in apples, grapes, blackberries, radishes, and red cabbage).
Several studies suggest anthocyanins help prevent heart attack by discouraging blood clots from forming. They also appear to improve night vision and to slow macular degeneration by strengthening tiny blood vessels in the back of the eye. Based on the guidelines for getting your five or more servings a day of fruits and vegetables, one serving of fresh blueberries would be ½ a cup, one serving of 100 percent blueberry juice is ¾ cup, and one serving of dried blueberries is ¼ cup.
