Ask Dr. Nandi: Are low doses of alcohol good for your brain?

I’ve always been fascinated by research into so-called “blue zones”. These are places around the world where people live much longer than the general population. Okinawa, Japan and the island of Sardinia off the coast of Italy are two of them. One thing we’ve learned about the people who live in blue zones is that they all drink small amounts of alcohol on a daily basis. Now, a new study shows that this practice may hold extraordinary benefits for the brain.
