"Among the most damaging of the free radicals are the superoxide ion, formed from oxygen, and the hydroxyl radical ion, formed from hydrogen peroxide. Singlet oxygen (oxygen atoms that are not bound in diatomic oxygen molecules) is another damaging free radical. Our bodies are not the only targets of free radicals. Free radical reactions are evident when a freshly cut apple begins to turn brown, oils become rancid, or rust develops on a car. Free radical attacks on the body can be divided into four types. 1. Free radicals can oxidize the fats and proteins that compose cell membranes." - Lester A. Mitscher and Victoria Toews, The Green Tea Book (Get the book.)

"It acts within the cell membrane, reacting with and neutralizing reactive oxygen species, including super oxide radical, singlet oxygen, hydrogen radicals, peroxide radicals, and hydrochloric acid.129 It has been used successfully in Germany for the treatment of diabetic neuropathy.130 Lipid peroxidation, which is free radical oxidation of the lipids, is increased in diabetic neuropathy and neutralized by alpha lipoic acid. ALA also tends to prevent protein glycosylation oxidation, because it acts as an antioxidant and stimulates glucose uptake by the cells." - Gabriel Cousens, There Is a Cure for Diabetes: The Tree of Life 21-Day+ Program (Get the book.)

"Antioxidant substance "gives away an electron" Free radical atom lacking an electron Antioxidant substance loses an electron Free radical receives an electron Antioxidant now has one less electron, Atom is now stable but has more to give The role of oxygen in free-radical formation The process of free-radical formation is known as oxidation, because free radicals are usually formed due to oxygen molecules, which are unstable. Oxygen easily combines with other substances. // gives us life, but its byproducts, if not controlled, can quickly end life." - Marc Sorenson, Solar Power For Optimal Health (Get the book.)

"Unlike any enzyme, however, vitamin C can quench the hydroxy radical directly.42 It also scavenges singlet oxygen.43 Low levels of vitamin C in the blood correlate with bladder cancer.44 When laboratory animals are given a dose of vitamin C corresponding to a human dose of 1.5 grams per day, it helps prevent these bladder tumors.45 Many other studies have also shown that vitamin C helps inhibit cancer,46 including a famous study by Dr. Pauling showing that severe cancer patients treated with vitamin C lived an average of 300 days longer than patients who did not receive vitamin C." - Hari Sharma, Freedom from Disease: How to Control Free Radicals, a Major Cause of Aging and Disease (Get the book.)

"Free radical attacks on the body can be divided into four types. 1. Free radicals can oxidize the fats and proteins that compose cell membranes. This free radical damage can lead to cell membrane instability, affect the ability of the cell to access food and oxygen and dispose of its waste products, and affect the cells' survival and reproduction. 2. Free radicals can damage the mitochondria of cells. Mitochondria are the "powerhouses" of cells where energy is actually generated. Obviously, when mitochondria are damaged, they are less effective in producing energy. 3." - Lester A. Mitscher and Victoria Toews, The Green Tea Book (Get the book.)

"Free radical activity isn't all bad—a small amount is actually crucial to our well-being. Free radicals are utilized by the immune system to attack harmful viruses and bacteria, and they may even play a role in the growth of blood vessels and skin during wound healing(l,2). It is when free radical production becomes excessive that problems occur. Remember all those peaceful protests you've seen on the television news that quickly degenerated into all-out riots? A similar scene occurs inside your body when free-radical production gets out of hand." - Anthony Colpo, The Great Cholesterol Con: Why Everything You've been Told About Cholesterol, Diet and Heart Disease is Wrong (Get the book.)

"Oxidative Stress and Diabetes Although there are many different types of free radicals, the ones that play an especially critical role in causing cardiovascular problems in people with diabetes include the superoxide radical and peroxynitrite. Research has shown that hyperglycemia (high levels of glucose in the blood) promotes the formation of free radicals, and therefore oxidative stress as well. In particular, hyperglycemia can cause excess production of superoxide. Oxidative stress, in turn, stimulates the development and progression of diabetes and the complications associated with it." - Steven V. Joyal, What Your Doctor May Not Tell You About Diabetes: An Innovative Program to Prevent, Treat, and Beat This Controllable Disease (Get the book.)

"By supplementing with antioxidants, Free radical Destruction of DNA we help our bodies keep up with the carnage. We can even get ahead of the game and reverse damage. What Are Anitoxidants? Antioxidants are compounds that render free radicals harmless and stop the chain-reaction formation of new free radicals. Where Do They Come From? There are three sources of antioxidants. 1. Several metabolic enzymes produced by the body are extremely effective antioxidant scavengers. Unfortunately, the body's ability to produce these enzymes fades dramatically in our late twenties. 2." - Jon Barron, Lessons from The Miracle Doctors: A Step-by-Step Guide to Optimum Health and Relief from Catastrophic Illness (Get the book.)

"If iron atoms are free and available, they can catalyze the Fenton reaction—allowing superoxide and hydrogen peroxide to react, with the hydroxy radical as the lethal result. The body thus attempts to keep a close watch on iron. Once the iron molecule has been encased in an enzyme, most researchers believe it is prevented from doing harm. But iron must be moved in the bloodstream to bring it to the cells for inclusion in enzymes. In a free state it would be dangerous, so it is carried by a protein molecule called transferrin." - Hari Sharma, Freedom from Disease: How to Control Free Radicals, a Major Cause of Aging and Disease (Get the book.) "The glutathione peroxidase enzyme uses a molecule of glutathione as its sword in the anti-free radical fight. It hands an electron from glutathione to hydrogen peroxide or lipid peroxide, thus satisfying their electron hunger and settling them down. The glutathione molecule, then short an electron, must be taken in hand by a second enzyme, glutathione reductase. This enzyme puts an electron back into glutathione, readying it once more for the fight. A third enzyme manufactures the glutathione itself from three amino acid molecules and four selenium atoms." - Hari Sharma, Freedom from Disease: How to Control Free Radicals, a Major Cause of Aging and Disease (Get the book.)

"Pulse radiolysis results support the mechanism of electron transfer (or H-transfer) from catechins to radical sites on DNA (Anderson et al., 2001). In black tea, all the theaflavins showed the same capacity to inhibit the production of superoxide. Green tea, black tea, and EGCG were shown to block the production of oxygen free radicals derived from the cooked meat mutagen 2-amino-3-methylimidazo[4,5-fJquinoline (IQ) in the presence of a NADPH-cytochrome P450 reductase (Hasaniya et al., 1997). These results support an antioxidant role of catechins in their direct interaction with DNA radicals." - Erich Grotewold, The Science of Flavonoids (Get the book.)

"Free radicals include the superoxide radical, the hydroxyl radical and hydrogen peroxide. A certain level of free radicals is essential for good health as they are involved in fighting infection and in the contraction of smooth muscles in the blood vessels. Cells have a number of ways of dealing with excess free radicals including the use of enzyme systems and specific antioxidants. What antioxidants do An antioxidant is a substance which gives up electrons easily so it can neutralize oxidants, including free radicals." - Nicola Reavley, The New Encyclopedia of Vitamins, Minerals, Supplements and Herbs (Get the book.)

"Hydrogen peroxide is actually somewhat different, as it is not itself short of electrons but easily converts in the body to compounds, such as the hydroxyl radical, that are short of electrons and that do the damage. Technically, compounds that are short of electrons are called free radicals. The superoxide ion and the hydroxyl radical are free radicals. Thus, reactive oxygen species include both oxygen-derived free radicals and compounds like hydrogen peroxide that are not themselves free radicals but that easily generate them." - John R. Smythies, Every_Persons_Guide_To_Antioxidants (Get the book.)

"High concentrations of the hydroxy radical, for example, can seriously damage the lipid membranes of nearby cells, creating lipid peroxide. These lipid peroxide molecules stimulate the production of leukotrienes and prostaglandins, the emergency chemicals which float off into intercellular spaces and the blood stream, acting as chemotactic beacons to draw in more phagocytes. The new phagocytes do even more damage, and the cycle feeds on itself." - Hari Sharma, Freedom from Disease: How to Control Free Radicals, a Major Cause of Aging and Disease (Get the book.)

"Long-term diabetes leads to fallen cognitive abilities probably due to the free radical generation and inflammation," he speculates. "Those free radicals could damage all tissues in the body, and if you have an excess of sugar in your body, you're doing this continuously," continues Dr. Dandona, who was startled by another discovery—that DNA in the white blood cells of diabetics is damaged by free radicals. "This may have implications for vascular disease and cancer." - Connie Bennett, C.H.H.C. with Stephen T. Sinatra, M.D., Sugar Shock!: How Sweets and Simple Carbs Can Derail Your Life-- and How YouCan Get Back on Track (Get the book.) "Dandona's interest in the subject began while studying overweight subjects whose harmful free radical levels went down after they restricted dietary intake and lost weight within a short period of time. This observation led him to wonder if certain types of food could produce harmful free radicals. In another study, Dr. Dandona found that "glucose increases inflammation and free radical generation within an hour of taking 75 grams of a glucose drink." - Connie Bennett, C.H.H.C. with Stephen T. Sinatra, M.D., Sugar Shock!: How Sweets and Simple Carbs Can Derail Your Life-- and How YouCan Get Back on Track (Get the book.)

"The effect is somewhat like a row of falling dominoes, with one free radical being created after another, leaving large numbers of damaged molecules in their wake. Oxidation is what also causes iron to rust or silver to tarnish. In the human body, common targets of free-radical oxidation include fats, sugars, proteins, and DNA. Your body accumulates free-radical damage throughout your lifetime. In fact, each cell in your body suffers an estimated ten thousand free-radical "hits" daily.

"Free radical damage is what causes low-density lipoprotein (LDL) cholesterol to adhere to artery walls, leading to hardening of the arteries and heart disease, for example. When free radicals damage DNA inside the cells, the result can be cell mutations that lead to cancer. Free radical assaults on your eyes may lead to cataracts and macular degeneration, the leading cause of vision loss in people over age 50. And many scientists believe that free radicals are the primary force behind aging itself. Unless something steps in the way, this free radical free-for-all can cause irreparable damage." - Prevention Magazine, Prevention's New Foods for Healing: Capture the Powerful Cures of More Than 100 Common Foods (Get the book.)

"Snead: "I have seen one lady who had had radical mastectomy123 done resulting in a lot of problems with pain 123 radical mastectomy: the removal of the breast, which has been diagnosed with cancer going into her arms and hands. She was prescribed pain pills and muscle relaxants as well as received steroid injections, but this did not result in any improvement. In fact, taking the drugs was making the condition worse, and she was tired of being sick and tired. It was only after chiropractic treatments that she started to improve." - Kenneth W Thomas, Ron Gilbert, Gerd Schaller, Side Effects: The Hidden Agenda of the Pharmaceutical Drug Cartel (Get the book.)

"Free radical damage • Free radical attacks on DNA, which is the genetic material of the cells, cause cells to die or mutate and possibly become cancerous. Free radicals may be involved in cancers of the lungs, cervix, skin, stomach, prostate, colon and esophagus. • Free radicals also attack blood fats which may lead to heart and blood vessel disease. When the LDL type of cholesterol reacts with free radicals it becomes damaged and this may lead to atherosclerosis. Unless LDL cholesterol becomes damaged it does not seem to be harmful." - Nicola Reavley, The New Encyclopedia of Vitamins, Minerals, Supplements and Herbs (Get the book.)

"SOD protects against the superoxide radical by converting it to hydrogen peroxide, which is then broken down to water. Copper also helps prevent iron from becoming a free radical. Summary for Copper Main functions: energy production, collagen synthesis, iron transport, and as an antioxidant. RDA: adults, 900 meg. Toxicity: rare. Tolerable upper intake level is 10 mg for adults. Deficiency can cause anemia. <0> Sources: nuts and seeds, avocados, and green leafy V ^ vegetables such as spinach." - Dr. Steve Blake, Vitamins and Minerals Demystified (Get the book.)

"For Cancer þ radical prostatectomy. In this procedure, the gland and surrounding tissue are removed. It can "cure" the cancer if the cancer has not spread. Losing the prostate also means you'll lose some bladder control, at least temporarily. One good option: nerve-sparing radical retropubic prostatectomy, so you'll be more likely to have erections. Minimally invasive, laparoscopic, or robotic laparoscopic nerve-sparing radical prostatectomy are variations. þ Radiation." - Mehmet C. Oz., M.D. and Michael F.

"Free radical. An atom or group of atoms that has at least one unpaired electron, and is therefore unstable. When free radicals occur within the body, they ricochet wildly, damaging cells and contributing to inflammation and the progression of cancer, heart disease, and other disorders. Free radicals naturally occur in the body during energy production, but can also be created in unhealthy amounts by the buildup of toxins and waste products in the body, poor diet, nutritional deficiencies, and exposure to environmental toxins and radiation. Geophagy." - Shari Lieberman, Alan Xenakis, Mineral Miracle: Stopping Cartilage Loss & Inflammation Naturally (Get the book.)

"The two types of phy-tonutrients (nutrients from plants) found in plums and prunes, neochlorogenic acid and chlorogenic acid, are effective antioxidants, particularly effective against a very destructive free radical called the superoxide anion radical, which can really wreak havoc on the cells in your body. Prunes Boast More Antioxidants Than Any Other Fruit The damage-preventing substances in prunes have been shown to help prevent damage to fats. Since our cell membranes and brain cells are largely composed of fats, preventing free radical damage to fats is a significant benefit." - Jonny Bowden, Ph.D., C.N.S., The 150 Healthiest Foods on Earth: The Surprising, Unbiased Truth About What You Should Eat and Why (Get the book.)

"Free radical. A highly reactive compound that damages cell membranes and other cell components, contributing to degenerative diseases, such as heart disease, cancer, premature aging, cataracts, and arthritis. Free radicals are found in air pollution, tobacco smoke, some foods, and pesticides. Some are produced by ultraviolet radiation; they are also manufactured during normal body processes. Chemically, free radicals have single, unshared electrons that are responsible for their high reactivity. French paradox." - Lester A. Mitscher and Victoria Toews, The Green Tea Book (Get the book.)

"Free radical: A highly chemically reactive atom, molecule, or molecular fragment with a free or unpaired electron. Free radicals are produced in many different ways, such as normal metabolic processes, ultraviolet radiation from the sun, nuclear radiation, and the breakdown in the body of spoiled fats. Free radicals have been implicated in aging, cancer, cardiovascular disease, and other kinds of damage to the body. See Antioxidants. Free-radical reaction: The cascade of chemical reactions that occurs when a free radical reacts with another molecule in order to gain an electron." - Robert Hass, M.S., Permanent Remissions (Get the book.)

"Free radical Chic The formation of free radicals, however, does not always occur to our benefit. Damaging effects of chemicals, sunlight, ozone, cigarette smoke, food additives, and oxygen contribute to the formation of free radicals that lead to aging and disease development. Day by day, the evidence suggesting that free radical damage to human tissue is the driving force behind conditions ranging from arthritis to cataracts to heart disease to cancer grows stronger. But the free radical theory, so en vogue today, is not new. Dr." - Dr. Mary Dan Eades, The Doctor's Complete Guide to Vitamins and Minerals (Get the book.)
