To add to the list of the health benefits of drinking wine is the latest theory that drinking just a glass a day can slow dementia. New research, published in the medical journal, Neurology, shows that drinking wine is particularly beneficial to those already experiencing memory problems. Study participants who consumed a drink a day — mostly red wine — developed dementia at an 85% slower rate than people with mild cognitive impairment who never drank alcohol. Researchers did warn, however, that excessive alcohol should be avoided so don’t forget to stop drinking.
