According to a study done in 2005, "nothing else comes close" to providing as many antioxidants as coffee. While fruits and vegetables also have tons of antioxidants, the human body seems to absorb the most from coffee.
Brigham and Women's Hospital and Harvard Medical School followed 112,897 men and women over a 20-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.
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. Dr. 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."
