constant attack of free radicals?
Antioxidants are substances that shield cells from harm by free radicals. Free radicals are highly reactive molecules capable of damaging cells and tissue and antioxidants fight against free radicals constantly. Free radicals are increased by injury, stress, pollution, and illness and since their discovery; they have been implicated as key players in ill health–as well as accelerating the aging process. The more free radicals that are formed, the further antioxidants are needed to neutralize them.
Beta-carotene and selenium, vitamins C and E, are examples of powerful antioxidants. And since no single antioxidant can defeat all the free radicals in the body, using them in combination increases their effectiveness. Although there are several enzyme systems inside the body that scavenge free radicals, the most beneficial ingredients are antioxidants. The body cannot manufacture these nutrients so they must be supplied in the diet-and useful sources include vegetables, fruits, and certain types of tea.
Vitamin A is an antioxidant that is good for the immune system and it defends the fatty tissue and cell membranes.

pumpkins,tomatoes,spinach,carrots,and pink grapefruit.
Good sources of vitamin C include citrus fruits and juices, green peppers, cabbage, spinach, broccoli, kale, cantaloupe, kiwi, and strawberries. Vitamin C is a powerful antioxidant which supports the immune system and the cardiovascular system.
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.
