Family meals are getting another big thumbs-up today, this time thanks to a new study examining the link between dinnertime and lower rates of risky behavior in teenagers.

"Family meals are the strongest factor that we've come across in any activity that families do," said William Doherty, a professor of family social science at the University of Minnesota. "It really tops them all as a predictor and contributor of a wide range of positive behavior."

Three-quarters of teens who reported having dinner with their family at least once a week said the interaction and the togetherness were the best part of the meal. Those who spent seven hours or less per week with their parents were twice as likely to use alcohol and twice as likely to say they expected to try drugs, compared with teens who spent 21 hours or more per week with their parents.
