This year, researchers at the University of California School of Medicine, San Diego, found that, compared with teetotalers, people who drank one glass of red or white wine a day were half as likely to develop nonalcoholic fatty liver disease (NAFLD), the most common liver problem in this country.

Experts have yet to pinpoint the reason, but they suspect an additional healthful compound in wine is at work.
