BOSTON (Daily Mail): Coffee could not only perk you up in the morning but could also help protect you from gum disease, researchers have found. They found that those who drank coffee were protected against gum disease. They believe the antioxidants could play a role - but admit they are not quite sure what is happening.  Lead author Nathan Ng of the Boston University Henry M. Goldman School of Dental Medicine, said: 'We found that coffee consumption did not have an adverse effect on periodontal health, and, instead, may have protective effects against periodontal disease.'
