It’s always nice to hear something you’re already doing is actually healthy, so here you go: coffee is good for your brain and might stave off dementia and Alzheimer’s, according to several recent studies. In the experiments, scientists found about three cups of the stuff disrupted a chain of events that can lead to neurodegenerative disorders. In one, caffeinated mice formed new memories 33 percent faster than their decaf counterparts. The research is still in the early stages, so don’t bank on your lattes as a cure-all, but feel free to drink up! And while you’re at it, turn your nose up at those chamomile-tea-drinking snobs.
