This is the third year that we have devoted the entire May issue to our "By the way, doctor..." question-and-answer format. It's quickly become one of our most popular issues.
The topics covered range from vitamin B12 supplements to gourmet salt to excessive belching. A total of 10 Harvard-affiliated doctors fielded questions.
We've also produced short videos featuring several of the doctors who answered questions — including yours truly. You'll find the videos posted on our Web site at www.health.harvard.edu/healthextra.
