Brigham and Women's Hospital and Harvard Medical School followed , men and women over a year period and, apparently, women who drink three or more cups of coffee a day are much less likely to develop skin cancer than those who don't.

The New York Times reports , "Scientists and many athletes have known for years, of course, that a cup of coffee before a workout jolts athletic performance, especially in endurance sports like distance running and cycling. Coffee could reduce your risk of developing Type 2 diabetes. Coffee also lowers risk of Type 2 diabetes , according to a study from The American Chemical Society. The study's researchers found that people who drink four or more cups of coffee a day reduce their chances of developing Type 2 diabetes by 50 percent.

Subsequently, with every additional cup, the risk gets lowered by 7 percent. Drinking coffee could help keep your brain healthier for longer.

Researchers from the University of South Florida and the University of Miami found that people older than 65 who had higher blood levels of caffeine developed Alzheimer's disease two to four years later than others with lower caffeine. Chuanhai Cao, a neuroscientist at the USF, and co-author of the study, said , "We are not saying that moderate coffee consumption will completely protect people from Alzheimer's disease. However, we firmly believe that moderate coffee consumption can appreciably reduce your risk of Alzheimer's or delay its onset.

You usually drink coffee when you are sleep-deprived, right? Well, that much-needed jolt not only keeps you awake, it makes you sharper.

You might think that it would be easier to roast the coffee, grind it into the required powder espresso, filter or instant and then begin the decaffeination process. Not, so says Stemman.

There are several ways to decaffeinate coffee but the most prevalent is to soak them in a solvent — usually methylene chloride or ethyl acetate. Methylene chloride can be used as a paint stripper and a degreaser as well an agent to remove caffeine. Caffeine has to be taken out of coffee beans before they are roasted Credit: Getty Images. The beans are first soaked in water and then covered in a solution containing either of these solvents. The caffeine is then drawn out by the solvent.

The solvent-laced water is then reused again and again until it is packed with coffee flavourings and compounds — pretty much identical to the beans, except for the caffeine and solvent. FDA rules allow up to 10 parts per million of residual methylene, but coffee decaffeination usually uses solutions with one part per million.

Two other methods use water. The Swiss Water method sees the beans soaked with water; the caffeine rich solution full of flavours is then strained though activated carbon which captures the caffeine.
