Description

They sound...ominous. Time to clear up the mystery of what, exactly, free radicals are―and learn how to combat them.

“Everyone’s body generates millions of free radicals every minute,” says internist Svetlana Kogan, founder of Doctors at Trump Place, in New York City.

Free Radicals: What Are They?  Definitions: (Wikipedia) Free radicals are atoms or molecules containing unpaired, single electrons Free radicals are usually unstable (highly reactive) toward losing or picking up an extra electron, so that all electrons in the atom or molecule will be paired. Free radicals can be positively charged, negatively charged, or neutral The Free radical often pulls an electron off a nearby molecule, causing the affected molecule to become a free radical itself.

Free Radicals: What Are They?  In common terms free radicals are: often used to describe damaged cells that can be problematic / perilous to neighboring healthy cells often injure the cell, damaging the DNA, which creates the seed for disease. Are sourced from irritants, pollution, smoke, and UVA and UVB rays, as well as normal cell processes, like cell metabolism. “Everyone’s body generates millions of free radicals every minute,” Svetlana Kogan, founder of Doctors at Trump Place, NYC.

Oxidation and Free Radicals  What is oxidation?  The process by which free radicals are formed (http://www3.amherst.edu/~dmirwin/Reports/BetterHealth.htm)  A chemical reaction in which there is the loss of electrons or gain (or increase in the proportion) of oxygen, hence, resulting in an increase in oxidation state by a molecule, atom or ion. (biology-online.org/dictionary/Oxidation)  damages cell membranes and other structures including cellular proteins, lipids and DNA.  Oxidation can be accelerated by stress, cigarette smoking, alcohol, sunlight, pollution and other factors. (http://www3.amherst.edu/~dmirwin/Reports/BetterHealth.htm)

Effects of Free Radicals  External, physical manifestations include: Wrinkles, sagged and dull or dry unhealthy-looking skin, hair, nails Deterioration of the eye lens, which contributes to blindness. Inflammation of the joints (arthritis). Skin allergies, swellings and infection, etc. Pale skin Accelerated spread of skin-related diseases

Effects of Free Radicals  Internal effects of free radicals include: Damage to nerve cells in the brain, which contributes to conditions such as Parkinson's or Alzheimer's disease. Acceleration of the ageing process. Increased risk of coronary heart disease, since free radicals encourage low density lipoprotein (LDL) cholesterol to adhere to artery walls. Certain cancers, triggered by damaged cell DNA.

How Antioxidants Help Prevent Oxidation  Antioxidants -  Are helpful in reducing and preventing damage from free radical reactions  has ability to donate electrons which neutralize the free radical without forming another. (Wikipedia)  can lose an electron to a free radical and remain stable itself by passing its unstable electron around the antioxidant molecule. (Wikipedia)  slow the process of aging by preventing free radicals from oxidizing sensitive biological molecules or reducing the formation of free radicals. (Wikipedia)  are molecules which can safely interact with free radicals and terminate the chain reaction before vital molecules are damaged (rice.edu/~jenky/sports/antiox.html)

What Can You Do “If a cell is damaged by free radicals, it wants to repair itself and will if it’s stimulated,” says Chapas.  Eat 5 servings of fruit or vegetables per day. This will ensure that you are developing your inherent antioxidant systems and that your diet is providing the necessary components.  Consider a more balanced approach to exercise. Failing that, consider supplementation.  Look for upcoming FDA recommendations, but be wary of advertising and media hype.  Do not oversupplement. Source: rice.edu/~jenky/sports/antiox.html
