I've been a coffee drinker for years and drank a pot a day (12 cups). I've been remarkably healthy, even into my late 40s. I haven't missed a day of work since last November, for example. My father had grey hair at the age of 40, my hair is still black with a few grey hairs...
I drink 4 cups in the morning and maybe another 2 cups at work these days. I grind my own beans at home, and use clean bottled water. I don't put anything in it (cream, sugar, etc.). I like the taste of it and enjoy the various flavors au natural.

Coffee: The New Health Food?
Plenty of health benefits are brewing in America's beloved beverage.
"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.
