What is an Antioxidant?

By Collin James

I am sure by now you have heard all about the antioxidants found in green tea. But, do you know what antioxidants are or how they work. The quality of a antioxidant can help prevent harmful diseases such as cancer and heart disease. I suppose your wandering why anything that is anti-oxygen can be good for your body.

Antioxidants do not do anything to oxygen. Antioxidants fight a chemical reaction called oxidation. This is the same process that causes metals to rust. Oxidation is the mingling between oxygen molecules and what they come in contact with. If it is living tissue where this occurs then that's when damage of disease occurs.

Free Radicals with in your body are highly unstable molecules that travel around your body causing nothing but major problems. Free radicals are generated by exposure to UV rays, toxins,smoking and other sources. The major source of the free radicals is from the oxygen molecule its self.

Paired together, oxygen travels through out your body and each molecule has its own electron. Often what happens is this double molecule splits into two half's which leaves one molecule with out and electron to go with it. Feeling of balanced, the single molecule races around your body trying to repair itself and find a new electron to pair up with.

But singlet oxygen doesn't just wait for a spare electron to float on by. Instead, it boldly steals one from some other molecule. This destabilizes the "new" molecule which, in turn, careens off to steal an electron from yet another molecule. The process of serial "electron stealing" damages cells, tissues, organs and even entire body systems, and is believed to be a major cause of cancer, heart disease, aging and many other conditions.

Now, this is where having antioxidants come into play. What antioxidants do is donate an electron to the lonely free radicals so they no longer have to steel electrons to feel balanced. Your body does produce antioxidants on its own, but not early enough to aid all the free radicals. That's where green tea can help you a lot,

Among others, these include beta-carotene, vitamins C and E, the mineral selenium, and various phytochemicals such as lycopene and quercetin. But the catechins, especially EGCg, are among the most powerful and effective antioxidants of all. - 15432
