Enjoying a beer or two at the local pub can reduce the chance of ending up with dementia, according to a study published in the Journal of the American Medical Association in 2003. This study reports that having one to six pints of stout, ale, or any other type of beer weekly reduced the risk of contracting dementia in adults over the age of 65. Although alcohol consumption isn't usually linked to increased cognitive function, this study suggests differently, when consumed in moderation, of course.
