Antioxidants क�या हैं

To make up for their shortage in electrons, these free radicals will react with certain chemicals in the body, and in so doing, they interfere with the cell's ability to function normally. But just as the body naturally produces free radicals, it also has a means to defend against its harmful effects. 

Antioxidants protect the body from harmful, excess free radicals, sweeping them up before they can cause damage. These days, when we talk about antioxidants, the first thing that comes to people's minds is "supplements." However, studies on antioxidant supplements are for the most part inconclusive and so far, no one study has come up with the same results during antioxidant supplements tests. 

Now, you can find antioxidant supplements in the form of Vitamin A capsules in almost any pharmacy or health food store. Beta-carotene antioxidant supplements generally come from orange, yellow, and green leafy vegetables and fruit. It has been observed that people who eat a lot of foods rich in beta-carotene are not generally prone to cancer. 

Oxidative stress is a process which many a scientist has linked with the development of chronic and degenerative diseases such as heart disease and cancer. Antioxidant fruits may be plain fruits, cereals, and vegetables. Some antioxidant fruits may also be taken in dried, powdered forms, like dietary supplements or pills. 

Anti aging antioxidants are natural substances but our bodies cannot produce them by themselves. That is why, we depend on plants for our source of anti aging antioxidants. Human beings are only one of a few animal species who can't produce their own anti aging antioxidants. We get most of our anti aging antioxidants from the fresh fruits and vegetables that we eat. 

In biological systems, the normal processes of oxidation are what lead to aging. Oxidation causes the production of substances called free radicals which are highly reactive. These free radicals can readily react with and damage other molecules. Note that it says "molecules" so that means free radicals don't make the distinction between foreign bodies and healthy cells.
