Or at least there wasn't for many families until researchers in the 1980s began looking at the data and doing all kinds of regression analyses that showed how a shared pot roast could contribute to kids' success and health. What the studies could not prove was what is cause and what is effect. Researchers speculate that maybe kids who eat a lot of family meals have less unsupervised time and thus less chance to get into trouble. Families who make meals a priority also tend to spend more time on reading for pleasure and homework. A whole basket of values and habits, of which a common mealtime is only one, may work together to ground kids. But it's a bellwether, and baby boomers who won't listen to their instincts will often listen to the experts: the 2005 CASA study found that the number of adolescents eating with their family most nights has increased 23% since 1998.
That rise may also reflect a deliberate public-education campaign, including public-service announcements on TV Land and Nick at Nite that are designed to convince families that it's worth some inconvenience or compromise to make meals together a priority. The enemies here are laziness and leniency: "We're talking about a contemporary style of parenting, particularly in the middle class, that is overindulgent of children," argues William Doherty, a professor of family social science at the University of Minnesota at Minneapolis and author of The Intentional Family: Simple Rituals to Strengthen Family Ties. "It treats them as customers who need to be pleased." By that, he means the willingness of parents to let dinner be an individual improvisation--no routine, no rules, leave the television on, everyone eats what they want, teenagers take a plate to their room so they can keep IMing their friends.
The food-court mentality--Johnny eats a burrito, Dad has a burger, and Mom picks pasta--comes at a cost. Little humans often resist new tastes; they need some nudging away from the salt and fat and toward the fruits and fiber. A study in the Archives of Family Medicine found that more family meals tends to mean less soda and fried food and far more fruits and vegetables.
Beyond promoting balance and variety in kids' diets, meals together send the message that citizenship in a family entails certain standards beyond individual whims. This is where a family builds its identity and culture. Legends are passed down, jokes rendered, eventually the wider world examined through the lens of a family's values. In addition, younger kids pick up vocabulary and a sense of how conversation is structured. They hear how a problem is solved, learn to listen to other people's concerns and respect their tastes. "A meal is about sharing," says Doherty. "I see this trend where parents are preparing different meals for each kid, and it takes away from that. The sharing is the compromise. Not everyone gets their ideal menu every night."
