Both blueberries and cranberries come packed with antioxidants! Rich in antioxidants, these fruit are a great source of vitamin C, vitamin B complex, vitamin E, vitamin A, zinc and iron. They are full of antioxidants that protect cells from damage from unstable molecules and free radicals. Cranberries have also been valued for their ability to help prevent and treat urinary tract infections. Cranberries contain certain acid which prevents the combination of calcium and phosphate ions to form insoluble stones. Hence, they are also beneficial against the formation of kidney stones.
