At least six studies indicate that people who drink coffee on a regular basis are up to 80 percent 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 percent reduced risk of colon cancer, an 80 percent drop in liver cirrhosis risk, and nearly half the risk of gallstones. 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.
