Free radicals are atoms with unpaired electrons. These atoms can result in a chain reaction. Free radicals can be dangerous when they interact with cell membranes or DNA. Cells can die or function poorly as a result of this. Antioxidants are the body's defense mechanism against free radicals.

Antioxidants can stop the chain reaction that is caused by free radicals. Beta-carotene, vitamin C, and vitamin E are some of the antioxidants that can fight free radicals. Selenium can also fight free radical damage. You have to get these nutrients from your diet because your body does not produce them.

Vitamin E

Vitamin E is a fat-soluble vitamin that is found inside whole grains, vegetables, fish oil, apricots, and fortified cereal. Women need to get 12 IU and men need to get 15 IU of vitamin E per day.

Vitamin C

Vitamin C is a water-soluble vitamin that is found in broccoli, spinach, strawberries, bell peppers, and kale. People should get 60 mg of vitamin C per day. Side effects can result if one takes in more than 2,000 mg of vitamin C.

Beta-carotene

Beta-carotene is vitamin A's precursor. Peaches, egg yolk, carrots, spinach, yams, and squash have beta-carotene. The RDA does not have a recommended amount of beta-carotene because it is converted into vitamin A. However, it is important to note that vitamin A can be dangerous if it is consumed in large amounts.
