Carrots are famous for being very beneficial for eyes – they protect and improve your vision. The Department of Agriculture recommends adults eat at least four servings of the vegetable every day because it has a lot of other benefits. They clean your teeth and gums, have lots of Vitamin A which protects your skin, and contains antioxidants that help prevent cancer. Carrots are also a great source of potassium. For a more delicious taste, add peanut butter.
