Your body protects itself from harmful substances like a soldier in battle. Think of antioxidants as part of this virtual army. Antioxidants are substances involved in protecting your cells against damage caused by unstable atoms, called free radicals. You get antioxidants from a variety of foods that include fruits, vegetables, nuts, grains, meat, poultry and fish. Free-radical damage is linked to heart disease, cancer and other diseases, but a diet high in antioxidants helps protect you from free radicals.
