Do we need antioxidants if we eat a balance diet? The answer is yes and no. Antioxidants are produced by the body or present in food. These nutrients can prevent or slow down oxidation processes in our body. When our body cells uses oxygen , the by product from these processes are free radicals which can cause damage to our body. Free radicals have an extra electrical charge that causes them to seek out other substances in the body in order to neutralize themselves. This initial reaction neutralize the free radical but in the process, another free radical is formed . A chain reaction then begins and thousands of free radical reaction can occur within seconds of the 1st reaction unless the extra free radical is deactivated.

With our current lifestyle ,people are too busy to cook or choose what they eat in order to obtain all the vitamins and antioxidants there body needs. Is taking anti oxidant supplement a cure to a bad diet? Here are some of the findings that will make you think twice before you gulp those supplements.

According to WEB MD, a new detailed analysis of human studies of beta carotene ,vitamin A and Vitamin E shows that people who take these antioxidant do not live any longer than those who do not take them. Those who take them have a higher risk of death than those who do not. This study was published in JAMA (Journal of he American Medical Association) where the investigators(physicians involved in the study) stated that they will no longer recommend beta carotene,vitamin A and E to their patients because these supplements offer no benefits,but did no harm.

Antioxidant supplements is not a magic bullet for disease prevention. There is no single capsule or supplement that is going to provide all your health needs. It is what you eat , your food choices and how you cook it , your lifestyle and your physical activity . Maintain a healthy weight,keep hydrated and eat a healthy diet is what matters. All the antioxidant rich foods are easily found in your local supermarkets,farmers market, or grow your own , to eliminate the free radicals from pesticide that comes along with the produce you purchase. If you must take supplements purchase them in combination with other antioxidant,for example in the form of multivitamins. Excessive intake of any one vitamin many times the required RDA can result in toxicty and can cause detrimental effect on your HDL (good cholesterol ) and increase incidence of autoimmune diseases. Consuming antioxidant rich food in excess of your RDA (recommended daily allowance) rarely cause toxicity and occur primarily with arctic explorer who consumed excessive amounts of polar bear liver (rich source of vitamin A).

The lesson: you can not correct a bad diet with supplements, if you do, you will missed out from the other nutrients that food provides. It is also more economical and fun to cook and eat food instead of gulping a capsule or tablet.
