Caffeine Good for Older Gals, No Benefit for Guys

A recently released French research study suggests that caffeine helps memory in older women. The study, conducted by INSERM – France's version of the NIH – followed 7,000 older men and women for several years and tested their mental acuity. Though it tended to diminish with age, women in the study who drank three or more cups of coffee per day were mentally sharper than those who drank less coffee or none at all. (Similar results were found in women who received a comparable amount of caffeine from tea.) Unfortunately, no benefits were found for the study's male participants.
