That's how many family dinners you should aim for per week.

Yes, you really can eat to your (child's) health: Research has linked family dinners with reduced risk of eating disorders, drug and alcohol use, and obesity among children and teenagers. And kids aren't the only ones who'll benefit from sitting down to turkey meat loaf and sweet potatoes. The family meal offers solid adult benefits, such as higher relationship satisfaction, enhanced mental and physical health, and an emboldened sense of life achievement, according to a 2009 Barilla survey. No wonder food manufacturers are using "health" campaigns to encourage family meals. Stouffer's new Let's Fix Dinner campaign touts facts like "Teens who have frequent family dinners are likelier to say they get mostly As and Bs in school." The truth is, no matter the age of your children, family dinners are smart.
