Antioxidants are substances that may protect cells in your body from free radical damage that can occur from exposure to certain chemicals, smoking, pollution, radiation, and as a byproduct of normal metabolism.
Dietary antioxidants include selenium, vitamin A and related carotenoids, vitamins C and E, plus various phytochemicals such as lycopene, lutein, and quercetin. You can find these antioxidants in many different foods that you're probably eating right now.
There are large amounts of antioxidants in fruits, dark green and brightly colored vegetables, fresh nuts, and whole grains. Fish is the best animal source of antioxidants, but eggs contain a small amount as well. Junk foods, such as highly processed fast foods tend to be much lower in antioxidants.
Health Benefits of Antioxidants
Consuming foods rich in antioxidants may be good for your heart health and may also help to lower your risk of infections and some forms of cancer. Increase your antioxidant intake by eating more nuts, seeds, legumes, fruits and vegetables.
