HI,\n\nAn antioxidant is a chemical that reduces the rate of particular oxidation reactions in a specific context, where oxidation reactions are chemical reactions that involve the transfer of electrons from a substance to an oxidising agent.\n\nAntioxidants are particularly important in the context of organic chemistry and biology. All living organisms maintain a reducing environment inside their cells, all cells contain complex systems of antioxidants to prevent chemical damage to the cells' components by oxidation. These antioxidants include glutathione and ascorbic acid and are substrates for enzymes such as peroxidases and oxidoreductases.\n\nA diet containing polyphenol antioxidants from plants is required for the health of most mammals, since plants are an important source of organic antioxidant chemicals. Antioxidants are widely used as ingredients in dietary supplements that are used for health purposes such as preventing cancer and heart disease. However, while many studies have suggested benefits for antioxidant supplements in laboratory experiments, several large clinical trials have failed to clearly demonstrate a benefit for the formulations tested, and excess supplementation may be harmful. It is logical to assume that a one dimensional approach to dietary supplementation with one specific antioxidant is not a panacea, since a broad diet rich in phytonutrients will yield thousands of different polyphenol antioxidants available for metabolism.\n\nRedgs,\n\nVenkat

This definitely seems to be a myth resulting from suppositions not based on any credible scientific studies. The Framingham study, a thirty year study of a group consuming coffee, came up with no such finding.

Nope, something in the fermentation process realeses the anti-oxidants proven to be beneficial in reducing cholresterol and other claimed health benefits.

Here are some of the benefits and risk of drinking coffee.\n\nBenefits\nCoffee increases the effectiveness of pain killers—especially migraine medications—and can rid some people of asthma. Some of the beneficial effects may be restricted to one sex, for instance it has been shown to reduce the occurrence of gallstones and gallbladder disease in men. Coffee intake may reduce one's risk of diabetes mellitus type 2 by up to half. While this was originally noticed in patients who consumed high amounts (7 cups a day), the relationship was later shown to be linear (Salazar-Martinez 2004).\n\nCoffee can also reduce the incidence of cirrhosis of the liver and prevent colon and bladder cancers. Coffee can reduce the risk of hepatocellular carcinoma, a variety of liver cancer (Inoue, 2005). Also, coffee reduces the incidence of heart disease, though whether this is simply because it rids the blood of excess fat or because of its stimulant effect is unknown. At the annual meeting of the American Chemical Society in Washington, D.C., on August 28, 2005, chemist Joe Vinson of the University of Scranton presented his analysis showing that for Americans, who as a whole do not consume large quantities of fresh fruits and vegetables, coffee represents by far the largest source of valuable antioxidants in the diet.[4]\n\nCoffee contains the anticancer compound methylpyridinium. This compound is not present in significant amounts in other food materials. Methylpyridinium is not present in raw coffee beans but is formed during the roasting process from trigonellin, which is common in raw coffee beans. It is present in both caffeinated and decaffeinated coffee, and even in instant coffee. 6\n\nCoffee is also a powerful stimulant for peristalsis and is sometimes considered to prevent constipation; it is also a diuretic.\n\nMany people drink coffee for its ability to increase short term recall and increase IQ. It also changes the metabolism of a person so that their body burns a higher proportion of lipids to carbohydrates, which can help athletes avoid muscle fatigue.\n\nSome of these health effects are realized by as little as 4 cups a day (24 U.S. fl oz, 700 mL), but others occur at 5 or more cups a day (32 U.S. fl oz or 0.95 L or more).\n\nSome controversy over these effects exists, since by its nature coffee consumption is associated with other behavioral variables. Therefore it has been variously suggested that the cognitive effects of caffeine are limited to those who have not developed a tolerance, or to those who have developed a tolerance and are caffeine-deprived.\n\nPractitioners in alternative medicine often recommend coffee enemas for "cleansing of the colon" due to its stimulus of peristalsis, although mainstream medicine has not proved any benefits of the practice.\n\n\nRisks\nMany notable effects of coffee are related to its caffeine content.\n\nMany coffee drinkers are familiar with "coffee jitters", a nervous condition that occurs when one has had too much caffeine. Coffee can also increase blood pressure among those with high blood pressure, but follow-up studies showed that coffee still decreased the risk of dying from heart disease in the aggregate. Coffee can also cause insomnia in some, while paradoxically it helps a few sleep more soundly. It can also cause anxiety and irritability, in some with excessive coffee consumption, and some as a withdrawal symptom. There are also gender-specific effects, in some PMS sufferers it increases the symptoms, and it can reduce fertility in women, also it may increase the risk of osteoporosis in postmenopausal women, and there may be risks to a fetus if a pregnant woman drinks 8 or more cups a day (48 U.S. fl oz or 1.4 L or more).\n\nA February 2003 Danish study of 18,478 women linked heavy coffee consumption during pregnancy to significantly increased risk of stillbirths (but no significantly increased risk of infant death in the first year).

Want a drug that could lower your risk of diabetes, Parkinson's disease, and colon cancer? That could lift your mood and treat headaches? That could lower your risk of cavities? \n\n\nIf it sounds too good to be true, think again. \n\n\nCoffee, the much maligned but undoubtedly beloved beverage, just made headlines for possibly cutting the risk of the latest disease epidemic, type 2 diabetes. And the real news seems to be that the more you drink, the better. \n\n\nReducing Disease Risk \n\n\nAfter analyzing data on 126,000 people for as long as 18 years, Harvard researchers calculate that compared with not partaking in America's favorite morning drink, downing one to three cups of caffeinated coffee daily can reduce diabetes risk by single digits. But having six cups or more each day slashed men's risk by 54% and women's by 30% over java avoiders. \n\n\nThough the scientists give the customary "more research is needed" before they recommend you do overtime at Starbuck's to specifically prevent diabetes, their findings are very similar to those in a less-publicized Dutch study. And perhaps more importantly, it's the latest of hundreds of studies suggesting that coffee may be something of a health food -- especially in higher amounts. \n\n\nIn recent decades, some 19,000 studies have been done examining coffee's impact on health. And for the most part, their results are as pleasing as a gulp of freshly brewed Breakfast Blend for the 108 million Americans who routinely enjoy this traditionally morning -- and increasingly daylong -- ritual. In practical terms, regular coffee drinkers include the majority of U.S. adults and a growing number of children. \n\n\n"Overall, the research shows that coffee is far more healthful than it is harmful," says Tomas DePaulis, PhD, research scientist at Vanderbilt University's Institute for Coffee Studies, which conducts its own medical research and tracks coffee studies from around the world. "For most people, very little bad comes from drinking it, but a lot of good." \n\n\nConsider this: At least six studies indicate that people who drink coffee on a regular basis are up to 80% less likely to develop Parkinson's, with three showing the more they drink, the lower the risk. Other research shows that compared to not drinking coffee, at least two cups daily can translate to a 25% reduced risk of colon cancer, an 80% drop in liver cirrhosis risk, and nearly half the risk of gallstones. \n\n\nCoffee even offsets some of the damage caused by other vices, some research indicates. "People who smoke and are heavy drinkers have less heart disease and liver damage when they regularly consume large amounts of coffee compared to those who don't," says DePaulis. \n\n\nThere's also some evidence that coffee may help manage asthma and even control attacks when medication is unavailable, stop a headache, boost mood, and even prevent cavities.

If I have strong coffee I have problems with my breath but weak coffee several times a day seems to be okay. The same with mountain dew which has a lot caffeine. I think the effect of caffeine had different effects over different people

What Coffee Can Do:\n\nImproves mental performance. \nBoosts physical energy. \nElevates and improves mood. \n \n\nResearchers at MIT found that "caffeine is \na mind-accelerating mood booster." \nIt increases mental performance. \nCaffeine stimulates reaction time, attention span, \nconcentration and acuity with numbers. As little \nas 32 mg of caffeine as much as in a single serving \nof cola or a 5-ounce cup of tea can give you a real \nmental and energy boost. \nCaffeine moves to your brain fast, with 20 to 30 \nminutes and lasts up to 6 hours. \n \n\nCaffeine also improves physical endurance. Studies \nshow that cyclists pedaled 7% harder and lasted \nin competition 20% longer after taking caffeine. \n\nTip\n\nDrink your caffeine before your meal for a bigger \nenergy boost and fatigue beater effect.

In general - I would recommend sticking with normal green tea as the amount of caffeine is so low that you have nothing to worry about.\n\nI would think that this decaffeinating process will decrease the amounts of some photochemical - however, boiling and steeping tea are more likely to lead to decreases in anti-oxidants. I'm sure what you are consuming is still very healthy.

Black tea does have caffeine, which isn't good for you, and it stains the teeth. However it does have antioxidants and trace amounts of essential vitamins and minerals. It is probably better to drink green tea. It has the same benefits without staining your teeth. Both black and green tea comes in a decaf variety

As was said, coffee and tee are good choices. These days coffee is said to actually have a few health benefits. Tea is possibly a better choice, although in truth the antioxidant properties of green tea are probably exaggerated, as my understanding is that plain old hot chocolate actually has a much higher antioxidant content (although obviously not a low calorie choice).

Hi Stella.  I am a retired Chiropractor so my 'ego' requires that I respond to your question with the SCIENTIFIC EVIDENCE that contradicts the medical doctor's opinion (who's opinion is offered with NO scientific support).\n\nThe following are exact quotes from the medical literature with the scientific reference for each quote.\n\n1) "Tea is one of the most frequently consumed beverages in the world.  It is rich in polyphenols, a group of compounds that exhibit numerous biochemical activities.  Green tea is not fermented and contains more catechins than black tea or oolong tea. ... several recent studies suggest that green tea polyphenols may promote health and reduce disease occurrence, and possibly protect against Parkinson's disease and other neurodegenerative diseases."  - Drugs Aging, 2003;20(10):711-21 (researchers from Baylor College of Medicine)\n\n2) "Catechins (in green tea) are in vitro and in vivo strong antioxidants.  In addition, its (green tea's) content of certain minerals and vitamins increases the antioxidant potential of this type of tea.  Recent human studies suggest that green tea may contribute to a reduction in the risk of cardiovascular disease and some forms of cancer, as well as to the promotion of oral health and other physiological functions such as anti-hypertensive effect, body weight control, antibactertial and antivirasic activity, solar ultraviolet protection, bone mineral density increase, and anti-fibrotic properties and neuroprotective power."  (Note: NO DRUG can do all of this, and green tea has very low risks for side effects - although it may induce asthma in some susceptible patients.) - Journal American College of Nutrition, April 2006;25(2):79-99\n\n3) "These findings confirm that green tea has excellent antioxidant properties..." - Food Chemistry and Toxicology, Dec. 2002;40(12):1745-50\n\n4) "Our data show that consumption of 4 cups of tea/day (green tea not black tea) is a feasible and safe approach and is associated with a significant decrease in urinary 8-OHdG (a measure of oxidative damage to your genes that may relate to cancer risks) among green tea consumers after 4 months of consumption." - Cancer Epidemiology and Biomarkers Prevention, Feb. 2004;13(2):242-9\n\nI hope this wasn't too long or complex to be helpful.  Be careful about 'expert opinions' that are not supported by specific documentation ('medical school' means 'drug company opinions').  The above info. is legitimate and confirmable by looking up the listed research studies on Pubmed.

"Antioxidants are important, naturally occurring nutrients that help maintain health by slowing the destructive aging process of cellular molecules. \nAntioxidants can also be important in improving immune responses and vaccine recognition in dogs and cats. This may be especially critical for young animals that are being vaccinated while their immune system is still developing. \nAntioxidants can reverse decreases in immune-cell function for senior dogs and cats. A blend of several antioxidants in moderate amounts may be more effective than high levels of one antioxidant."\n\nMostly found in Green Tea, fruits, and vegetables.
