Q. What are “antioxidants”? and what do they do?

I’ve been hearing about antioxidants for quite some time now, they are supposedly help to keep us younger. What do they do and is it true?
A1When every biological system works- it creates oxidants. These are materials that are very active and they “look for” something to react with. So when you eat (an example) there are a lot of oxidants created. they move around in the colon and they usually react with colon cells, thus destroying them. This also happens while breathing, cell metabolism and a lot of biological processes. Antioxidants counteract these free oxidants and stop their harmful reaction.
A2An antioxidant is a molecule capable of slowing or preventing the oxidation of other molecules, and although oxidation reactions are crucial for life, they can also be damaging, hence, plants and animals maintain complex systems of multiple types of antioxidants, such as glutathione, vitamin C, and vitamin E. Low levels of antioxidants causes oxidative stress and may damage or kill cells, and oxidative stress might be an important part of many human diseases.
A3Antioxidants are substances that may protect your cells against the effects of free radicals. Free radicals are molecules produced when your body breaks down food, or by environmental exposures like tobacco smoke and radiation. Free radicals can damage cells, and may play a role in heart disease, cancer and other diseases.
free radicals are believed to be a reason for acceleration of aging.
