Coffee is among the most widely consumed beverages in the world, and a recent expert panel says that the preponderance of scientific evidence suggests that moderate coffee consumption (3-5 cups per day) may be associated with reduced risk of certain disease conditions, such as Parkinson's disease. Some research in neuropharamacology suggests that one cup of coffee can halve the risk of Parkinson's disease. Other studies have found it reduces the risk of Alzheimer's disease, kidney stones, gallstones, depression and even suicide.
