Our bodies have the ability to repair this damage However, as we get older, these repair mechanisms start to break down. resulting in signs of aging such as wrinkles. Free radicals are actually produced by our bodies .. but the ir numbers can also increase because of the food we eat Besides avoiding foods thatcould potentially produce more free radicals, eating foods that contain certain vitamins and micronutrients can also keep us looking young. These vitamins help produce molecules called antioxidants,. which actually help reduce the production of free radicals. Even better, foods containing antioxidants are not rare Common antioxidants, like vitamins A and E, can be found in many dark-colored vegetables.
