Health Benefits of Coffee

Overall Health Benefits

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? If it sounds too good to be true, think again. Coffee, 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.

The Benefits of Caffeine

"The evidence is very strong that regular coffee consumption reduces risk of Parkinson's disease and for that, it's directly related to caffeine," DePaulis tells WebMD. "In fact, Parkinson's drugs are now being developed that contain a derivative of caffeine based on this evidence."

Reducing Disease Risk

After 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 covenanted 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.

Their findings, reported just two weeks ago, are very similar to those in a less-publicized Dutch study last year. 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.

But you can get other benefits from coffee that have nothing to do with caffeine. "Coffee is loaded with antioxidants, including a group of compounds called quinines that when administered to lab rats, increases their insulin sensitivity" he tells WebMD. This increased sensitivity improves the body's response to insulin. That may explain why in that new Harvard study, those drinking decaf coffee but not tea beverages also showed a reduced diabetes risk, though it was half as much as those drinking caffeinated coffee. "

We don't know exactly why coffee is beneficial for diabetes," lead researcher Frank Hu, MD, tells WebMD. "It is possible that both caffeine and other compounds play important roles. Coffee has large amounts of antioxidants such as chlorogenic acid and tocopherols, and minerals such as magnesium. All these components have been shown to improve insulin sensitivity and glucose metabolism."

"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.

Consider 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.

Coffee 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.

There'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.
