antioxidant An example of something that is described as antioxidant are pomegranates. An antioxidant keeps a substance from degrading or decaying by inhibiting the chemical reaction called oxidation, the reaction of substances to exposure to oxygen molecules. An example of an antioxidant is wax used on a car to prevent rust. The definition of an antioxidant is something that prevents or repairs damage that has been done to the body by oxidation. An example of an antioxidant is Vitamin A. a substance that slows down the oxidation of hydrocarbons, oils, fats, etc. and thus helps to check deterioration: antioxidants are added to many products, esp. foods and soaps.

Antioxidants Antioxidants can protect your body's cells from damaging oxidation much like oil or paint protects your car from rust. Oxidation, which is the loss of an electron, sometimes produces free radicals that can cause oxidative stress or damage to the cells.

What Are Antioxidants? Where Can I Find Them? Antioxidants can stabilize free radicals before they damage your body's cells. Oxidation is a natural process, so a diet rich in antioxidants is necessary for optimal health. Your body's defenses against oxidative stress, or the damage caused by free radicals, become less effective with age.ome antioxidants, such as phytochemicals, are found in beverages such as wine and tea. What Antioxidants Are and How They Can Help You. Antioxidants are part of the vitamins, minerals and nutrients present in foods.

List of Antioxidants | antioxidant List of Antioxidants | antioxidant. List of Antioxidants: Antioxidants include a group of vitamins, minerals, herbs and enzymes that help to protect the body from the formation of free radicals. Free radicals are substances or electromagnetic fields that cause damage to cells thus impairing the immune system. Free radicals are thought to cause aging and diseases such as cancer.

The Disease-Fighting Power of Polyphenols Polyphenol: A kind of chemical that (at least in theory) may protect against some common health problems and possibly certain effects of aging.Polyphenols act as antioxidants. They protect cells and body chemicals against damage caused by free radicals, reactive atoms that contribute to tissue damage in the body.For example, when low-density lipoprotein (LDL) cholesterol is oxidized, it can become glued to arteries and cause coronary heart disease.olyphenols act as antioxidants.

Vitamins and minerals functioning as antioxidants with supplementation considerations There is a delicate balance between the amount of free radicals generated in the body and the antioxidants needed to provide protection against them. An excess of free radicals, or lack of antioxidant protection, can shift this balance resulting in oxidative stress.ertain nutrients serve as antioxidants or are components of antioxidant enzymes. Antioxidants include vitamins C and E, carotenoids, and antioxidant enzymes containing Se, Cu, Mn, Fe or Zn.

- Antioxidants are natural substances that may stop or limit the damage caused by free radicals. Your body uses antioxidants to stabilize the free radicals. This keeps them from causing damage to other cells. Antioxidants can protect and reverse the damage caused by oxidation to some extent.he cells in your body are exposed to oxygen every day. Oxygen is important for your body’s health, but exposure to oxygen also causes oxidation. In oxidation, body chemicals are altered and become what are known as free radicals.

Antioxidants: What You Need to Know As the name implies, antioxidants are substances that are capable of counteracting the damaging, but normal, effects of the physiological process of oxidation in animal tissue.Antioxidants are nutrients (vitamins and minerals) as well as enzymes (proteins in your body that assist in chemical reactions).They are believed to play a role in preventing the development of such chronic diseases as cancer, heart disease ,stroke, Alzheimer's disease, Rheumatoid arthritis, and cataracts.xidative stress occurs when the production of harmful molecules called free radicals is beyond the protective capability of the antioxidant defenses. Free radicals are chemically active atoms or molecular fragments that have a charge due to an excess or deficient number of electrons.
