Health benefits of blueberries include neutralizing free radicals, reducing body fat, limiting risk factors for cardiovascular disease, promoting urinary tract health, preserving eyesight, improving brain health, dissolving cholesterol, fighting cancer and reversing depression. Blueberries are high in fiber, vitamin C, antioxidants and flavonoids, and 1 cup is less than 100 calories. Blueberries are used in smoothies, salads, shakes and yogurt.

Anthocyanin is the main antioxidant in blueberries and gives the fruit its dark blue color. One cup of blueberries contains nearly 25 percent of the recommended daily supply of vitamin C. Blueberries contain carotenoids, a class of antioxidants that help vision. Some antioxidants in blueberries reduce the risk of heart disease by flushing out cholesterol.

Nutrients in blueberries improve brain capacity and motor skills. Compounds, such as pterostilbene and ellagic acid, work alongside anthocyanin to help prevent cancer. Both of these benefits slow the process of aging.

Blueberries help with digestion and urination. High-fiber content makes the berries easier to digest. One cup of blueberries provides 14 percent of the recommended daily intake of fiber. One compound prevents bacteria from adhering to bladder walls to reduce the chances of urinary tract infections, much like the effect of drinking cranberry juice.
