There are three kinds of studies we hear about. (1) Something incredibly obvious turns out to be true. (2) Something you like is good for you. (3) Something you like is bad for you. Obviously we prefer No. 2s, like this study out of Norway that says drinking wine—especially if you’re a woman—might make you smarter.
A large prospective study of 5033 men and women in the Tromsø Study in northern Norway has reported that moderate wine consumption is independently associated with better performance on cognitive tests. The subjects (average age 58 and free of stroke) were followed over 7 years during which they were tested with a range of cognitive function tests. Among women, there was a lower risk of a poor testing score for those who consumed wine at least 4 or more times over two weeks in comparison with those who drink [less than] 1 time during this period. The expected associations between other risk factors for poor cognitive functioning were seen, i.e. lower testing scores among people who were older, less educated, smokers, and those with depression, diabetes, or hypertension.
