Health problems such as heart disease, macular degeneration, diabetes, cancer etc are all contributed by oxidative damage. Indeed, a recent study conducted by researchers from London found that 5 servings of fruits and vegetables reduce the risk of stroke by 25 percent. Antioxidants may also enhance immune defense and therefore lower the risk of cancer and infection.

Some of the most common antioxidants are:

Vitamin A and Carotenoids. Found in carrots, squash, broccoli, sweet potatoes, tomatoes, kale, collards, cantaloupe, peaches and apricots (bright-colored fruits and vegetables).

Vitamin C. Found in citrus fruits like oranges and lime etc, green peppers, broccoli, green leafy vegetables, strawberries and tomatoes.

Vitamin E. Found in nuts and seeds, whole grains, green leafy vegetables, vegetable oil and liver oil.

Selenium. Found in fish and shellfish, red meat, grains, eggs, chicken and garlic.

Supplementing one's diet with an antioxidant dietary supplement is crucial. With all the toxins in our environment experts say that are cells actually contain 400 new toxins that didn't exist 45 years ago. In fact, researchers have concluded that over 70% of all diseases, including aging, are caused by oxidants as free radicals.

Oxidation on a car is called rust. Oxidative stress in the body is rusting in the cell, which injures or destroys it. This is why choosing a quality antioxidant supplement is so vital to one's health.
