I’m delighted, as I sit here at Starbucks, enjoying my first of many cups of coffee today, to write about the results of the newest study of coffee’s health effects. Researchers from the University of South Florida say that drinking five cups a day can reverse the memory problems associated with Alzheimer’s disease!

The scientists base this advice on a study of mice with dementia. Every day, they gave some of the mice water laced with caffeine (the equivalent to 5 cups/day for us); they gave the others plain water. After two months, they tested all of the mice on memory games and — surprise, surprise — the caffeinated ones performed much better. What’s more, compared with control mice, the brains of the caffeinated mice had half the level of protein plaques — the hallmark of Alzheimer’s disease in humans.

Hurray! I’m going to order another cup.

(This is definitely selective reporting, of course, as plenty of other studies are revealing the various ways in which caffeine consumption is bad for us. I’d just prefer not to write about those!)
