Blueberries are very rich in antioxidants called anthocyanin, vitamin C, B vitamins, vitamin E, vitamin A, copper (which strengthens immunity and has an antibacterial role), selenium, zinc, iron (promotes immunity by increasing hemoglobin and oxygen concentration in the blood) and thus stimulates the immune system and prevents infections. Blueberries have been shown to be helpful for cancer patients because they contain certain compounds, such as pterostilbene (excellent in the remedy of colon and liver cancer) and ellagic acid, which in combination with anthocyanin and other antioxidants such as vitamin C and copper, can lead to the prevention or cure of cancer.
