By Bryan J Hooper

There is lot of talk about the fitness benefits of antioxidants in the news and in current health studies. And while that might be attention-grabbing news, some of you may be wondering what antioxidants are and what they accomplish. Are there various types of antioxidants? How do we obtain a sufficient amount of them in the food that we eat? And how does eating a diet high in antioxidants srenghthen our bodies capability to defend against free radicals?

These substances called antioxidants guard our cells from the harmful damage caused by free radicals. The free radicals damage our cells by stealing electrons from them and forcing them to become unstable.The human body creates free radicals in small quantities,and stress,injury,illness and pollution increase the levels of the free radicals in ourselves.They have recently been discovered as negative factors in accelerating our aging process.The more free radicals that we allow in our bodies,the more antioxidants we need to eradicate them.

Vitamins C and D, and slenium and beta carotene are examples of some of the most powerful antioxidants. By combining all of them together you can create a powerful immune system and effectively destroy the free radicals. Our body produces a few enzymes that feed on the free radicals, but they are not enough control all of the free radicals that are introduced to our bodies. We dont manufacture antioxidants in our bodies, therefore we need to consume foods that are high in antioxidants like fruit and vegetables.

Vitamin A helps bone and teeth development and promotes good vision. As an antioxidant, it protects cell membranes and fatty tissue, helps repair damage caused by air pollutants, and supports the immune system. Foods rich in vitamin A include liver, eggs, and some dairy products.

A good antioxidant for lowering the risk of cancer and heart disease is found in
Cartenoids. These nutrients are found in a variety of vegetables and fruit like
pumpkins,tomatoes,spinach,carrots,and pink grapefruit.

The antioxidant found in vitamin C help support the cardiovascular system and the immune system. Vitamin C can be found in many citrus products such as
oranges,lemons,spinach,cantaloupe,and kiwi.

Vitamin E is a potent antioxidant by itself, but is magnified when it is ingested with other antioxidants such as vitamin C, selenium, and beta carotene. Good sources include nuts, seeds, fish oils, whole grains, and apricots.

Flavonoids enhance the beneficial activities of vitamin C and can help support a healthy immune system. They are primarily found in fruits and vegetables and some teas. Flavonoids are a pigment in plants and fruits that acts as an antioxidant to protect against damage from free radicals. In the body, flavonoids enhance the beneficial activities of vitamin C and can help support a healthy immune system.
