Deep-fried foods, like French fries, contribute to free radical damage in your body.

Emre Nacigil

Definition: As the body uses oxygen, these by-products cause oxidative damage to the cells of the body. Free radicals come from smoking, pollution, poisons, fried foods, and as a by-product of normal metabolism.

Free radical damage is associated with an increased risk of many chronic diseases. Antioxidants such as vitamin C, carotenes and vitamin E reduce the damage caused by free radicals.

It seems the most effective antioxidants come from foods you eat. Taking dietary supplements doesn't appear to offer the same benefits.
