What Are Free Radicals?:
An atom or group of atoms that has at least one unpaired electron and is therefore unstable and highly reactive.
Free Radicals
Free Radicals play an important role in a number of biological processes, some of which are necessary for life, However, because of their reactivity, these same free radicals can cause unwanted side effects resulting in cell damage.
Free radical—An unstable, highly reactive molecule that occurs naturally as a result of cellular metabolism, but can be increased by environmental toxins, ultraviolet and nuclear radiation.
Free Radicals: Are highly reactive, imbalanced molecules that are the byproducts of normal metabolism and are associated with the degenerative aging process.

[edit] Free radicals and glycation
Two very prominent theories of aging are the free radical theory and the glycation theory, both of which can explain how CR could work.
Free radicals are produced naturally by many cellular processes, but more importantly, their output can be greatly increased by exposure to environmental factors such as pollution, tobacco smoke and radiation.
Free radicals are charged particles. They have a high degree of association with cancer cell formation. Iron supplements to not produce free radicals.
Free radicals are molecules in the body that attack healthy cells and cause damage that can lead to disease. The health benefits of antioxidants are largely due to their effects in protecting against damage from these free radicals.
Free radical - molecules containing an odd number of electrons resulting in an open bond or half bond, making them highly reactive and as a result, potentially destructive.
A free radical is a chemical "species" with an unpaired electron that can be neutral, positively charged, or negatively charged. Although a few stable free radicals are known, most are very reactive.
Destroys free radicals inside and outside cells. Helps in the formation of connective tissue, the healing of wounds, and iron absorption, and also helps to prevent bruising and keep gums healthy.

Besides playing a paramount role as an anti-oxidant and free radical scavenger, it has been suggested to be an effective antiviral agent by some very respected scientists.
It only becomes bad when it becomes oxidized or modified by an excess of free radicals.
Antioxidants act as "free radical scavengers" and work to prevent and repair damage done by free radicals in the body. For this reason, foods naturally containing antioxidants are an essential part of a healthy diet.
The Lung Care system provides nutrients that: Protect against free radical damage Promote healthy lung function and breathing capacity by maintaining clear respiratory passages Promote healthy muscle function within the respiratory system Support ...
Antioxidants are special nutrients, found in the foods we eat, that act as neutralizers for the damaging free radicals that affect our body's cells.
Foods (but not supplements) rich in antioxidants and betacarotene may be helpful in reducing asthma attacks, as their ability to neutralize free radicals may help to protect the lungs.
Antioxidants are believed to help the body's cells resist damage caused by free radicals, which are formed by normal bodily processes such as breathing or environmental contaminants like cigarette smoke.
Vitamin E is a natural antioxidant that neutralises free radicals before they can cause any damage. It can be applied to the skin to prevent scarring and keeps red blood cells healthy.
Deficiency signs ...
This is caused by free radicals, which are molecules that do not have electrons. In search of their missing electron, free radicals destabilise other molecules, causing tissue to change and age.
Reactive Oxygen Species, more popularly known as "free radicals". Molecules with one too few electrons. They strip electrons from other molecules in the body, damaging the other molecules in the process.
Because it contains all these nutrients, including powerful antioxidants, real extra virgin olive oil is beneficial to health and protects us from damage by free radical oxidation.
Vegetables should make up the largest portion of your diet, as the antioxidants in fresh produce have a powerful effect against the free radicals in our bodies.
Glassman explains that exercise actually creates free radicals, which is why it is vital to eat a diet rich in antioxidants when you have an active lifestyle.
"Eating berries helps protect the tissues in the body from injury by neutralizing the effects of free radicals before they do damage," says Gary Stoner, Ph.D., chairman of environmental health at Ohio State University, in Columbus.
The antioxidant properties also protect smokers from the harmful effects of free radicals.
Tomatoes, carrots, and dark orange vegetables are good sources of carotenoids, which trap free radicals.
When exposed to oxidant stress, n-6 fatty acids are vulnerable to attack by free radicals and oxidation into lipid peroxides (Halliwell and Chirico, 1993).
Antioxidant
A molecule capable of absorbing free radicals (highly reactive molecules produced during many metabolic processes that can damage DNA). Whether eating foods high in antioxidants is beneficial to health is contentious.
Antioxidants: Plant substances that naturally occur in food that protect the body from free radicals, or unstable oxygen molecules, which can damage cells and lead to poor health; ...
These can act as powerful antioxidants, protecting the body from harmful free radicals and helping to protect against certain chronic diseases such as cancer.
Antioxidant vitamins such as beta-carotene and vitamins C and E work their magic by 'mopping up' harmful free radicals, which can cause oxidation of LDL cholesterol - a problem that potentially speed up the process of the narrowing of arteries.
Antioxidants
Antioxidants protect the body against the destructive effects of free radicals by neutralizing them before they can cause cellular damage and disease.
Vitamins A, C and E and the minerals zinc and selenium help protect the heart by helping to destroy the 'free radicals' produced via oxidation in the body.
