What is the role of antioxidants in the human body?

by
Antioxidants are nature’s way of protecting the body and cells from damaging free radicals. Free radicals are unstable molecules that are generated by sun exposure, stress and as part of the natural aging process. Free radicals damage cells, DNA and collagen.

Just so, what does an antioxidant do to the human body?

Antioxidants are substances that may protect your cells against the effects of free radicals — molecules produced when your body breaks down food or is exposed to tobacco smoke and radiation. Antioxidants, such as vitamins C and E, and carotenoids, may help protect cells from damage caused by free radicals.

How do antioxidants work in the human body?

They donate electrons to free radicals, which neutralizes them and prevents them from causing harm. Bottom Line: Antioxidants are molecules that fight damage by free radicals, unstable molecules that can harm cellular structures. Antioxidants do this by giving electrons to the free radicals and neutralizing them.

What is the purpose of an antioxidant?

Cells may function poorly or die if this occurs. To prevent free radical damage the body has a defense system of antioxidants. Antioxidants are molecules which can safely interact with free radicals and terminate the chain reaction before vital molecules are damaged.

Do Antioxidants help prevent cancer?

Antioxidants are substances that may protect cells from the damage caused by unstable molecules known as free radicals. Free radical damage may lead to cancer. Antioxidants interact with and stabilize free radicals and may prevent some of the damage free radicals otherwise might cause.

What is the use of antioxidants?

An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells. Antioxidants such as thiols or ascorbic acid (vitamin C) terminate these chain reactions.

Is there antioxidants in coffee?

Coffee is a rich source of disease-fighting antioxidants. And studies have shown that it may reduce cavities, boost athletic performance, improve moods, and stop headaches — not to mention reduce the risk of type 2 diabetes, colon cancer, liver cancer, gall stones, cirrhosis of the liver, and Parkinson’s diseases.

Are oxidants good for you?

Why is oxidation bad in the body?

When one molecule gives up an electron to another, scientists say it is “oxidized.” Oxidation happens through chemical reactions in our bodies all the time. The process creates “free radicals,” which can cause damage that raises our risk for heart attack, stroke, cancer and other problems.

What is an antioxidant in food?
