Health Benefits of Tea and Coffee

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 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.

Indeed, the brain responds to coffee in a unique way. The extra alertness can often help to focus, concentrate and even remember details at a higher rate.

Coffee also aids workers to concentrate. 200mg of caffeine can significantly reduce the tendency towards sleepiness and convert grogginess to alertness and concentration. In fact, coffee usually helps workers for at least 5-7 hours which can help out for the entire shift.

Also, many workers will find themselves feeling especially groggy after lunch. This is also an efficient time to drink coffee because attention, memory and concentration are most likely a part of the job. There are also studies that have shown that people who drink coffee over the lunch hour are more contented and more interested in their work, as well as more alert. However, it is also important that addiction to coffee can eventually increase the rate of irritability.

It is also important to consider what is necessary to perform at your best. Coffee can actually increase information processing by 10%. This is especially important for repetitive work. Coffee can also help to deal with the problem of headaches.
