We recently published a story about how beer, or regular alcohol intake, can be good in terms of lowering your risk of developing diabetes. Now there's yet another study, one that was done by University of California, San Diego, that claims that moderate to heavy alcohol drinkers are more likely to reach the age of 85 without developing dementia and related.

Based on the results of the study drinkers have way better chance of avoiding dementia than non-drinkers. The study says that "Moderate and heavy drinkers had 2-fold higher odds of living to age 85 without cognitive impairment relative to non-drinkers."

But what is moderate drinking? According to them, it's consumption of up to one alcoholic beverage a day. And heavy drinking? Anything above three or four drinks a day. And excessive drinking is anything above that.

I'm not sure if the study made any difference what alcoholic beverage is being consumed.

And of course, now let's get to the fine print. First of all, the study was conducted between 1984 and 2013 and the number of test subjects was just 1344. And what's more, all people studied were middle class white people.

So in reality, beer might actually not help with dementia. As even the UC San Diego said in a statement themselves, "[The study] does not suggest drinking is responsible for increased longevity and cognitive health. Alcohol consumption, particularly wine, is associated with higher incomes and education levels, which in turn are associated with lower rates of smoking, lower rates of mental illness and better access to health care."

Well, it's all understandable, but once you think about it, what was this study good for at all then?
