Moms concerned about keeping their kids fit and trim may want to encourage an increasingly threatened institution: the healthy family meal.
That's true even if the family's goals of eating together each day falls short occasionally, according to a study published in a recent issue of the journal Obesity Research.
Eating together as a family has long been recommended by nutrition experts.
"I certainly recommend people eat together at least a few times a week," said Lola O'Rourke, a Seattle dietitian and spokeswoman for the American Dietetic Association. Doing so helps parents teach kids healthy eating habits, she said, and also gives them some control over what their children eat.
The family meal may be more important than ever, experts say, especially in the wake of a government study released earlier this month that found high-calorie, low-nutrient junk food readily available in nine out of 10 U.S. schools.
In their study on family dinners, Dr. Abdullah A. Mamun, of the University of Queensland in Brisbane, Australia, and colleagues evaluated data on nearly 3,800 children, half girls and half boys, following them from birth to age 14.
They found the prevalence of overweight at age 14 was 24.1 percent for the boys and 27.1 percent for the girls.
They also looked at whether or not families ate together regularly, and quizzed mothers on their attitudes towards the family meal.
While 79 percent of the mothers said their family ate together at least once a day, only 43 percent said they felt it was important to eat together, the Australian team found.
Then the researchers focused on the children of mothers who didn't say it was important to eat together. According to the study, those children were 30 percent more likely to be overweight by age 14 compared with kids born to moms who valued the family meal.
The researchers found no association between the mothers' report of how often the family actually did eat together and the chances of the teen being overweight by age 14, however.
So why might a mother's attitude to family meals matter, even when her family often fails to get together for lunch or dinner? Researchers speculate that maternal attitudes towards the importance of family meals may reflect a broader respect for good nutrition. This might extend to practices such as keeping healthy foods in the house or limiting the amount of times their children can eat "junk food."
That interpretation makes sense to O'Rourke. "You would think people who are more concerned about family meals are also probably more concerned about nutrition," she said.
Mothers who encourage family dinners may also be providing more emotional support to their teens, she said, or building self-confidence in them so they are less likely to turn to food for stress-relief.
"In the past we have seen [in research] that a higher incidence of family meals is associated with a better nutrient intake, healthier meals," she said.
Eating together as a family, at least a few times a week, gives everyone a chance to connect, she said, and "parents have more influence in terms of what is being put on the table."
Parents can also take the opportunity to discuss healthy eating habits and set guidelines for eating at school, where junk food is common. A study released in early September by the Government Accountability Office, the investigative arm of Congress, found that nine out of 10 schools have candy, soda, pizza and other snacks readily available, and that schools are one of the largest sources for unhealthy food for today's children.
In the sample, the GAO surveyed 656 schools, with 51 percent of the principals responding. Vending machines were available in nearly all high schools and middle schools but less than half of elementary schools. Junk food has become more common in middle schools in the past five years, the survey found. And the investigators found that vending machine foods and "junk foods" offered in a-la-carte lines in school cafeterias are crowding out healthier choices.
The result? Obesity among children and teens has more than doubled in the past three decades, according to experts at the Institute of Medicine.
Parents can set guidelines for making good choices at school, however.
"Don't tell them they absolutely can't have pizza or whatever it is [they want to eat]," O'Rourke said. "Saying no you can't have it at all will backfire." Rather, she suggested, ask them to limit foods such as pizza to once a week or so at school.
Another good idea, O'Rourke said, is to "create these foods at home in healthier versions, such as pizza with less cheese, using whole wheat crust and more veggies as toppings."
Health Tip: Prevent Eating Disorders
The causes of eating disorders, such as anorexia nervosa and bulimia, are often multi-faceted, which can make the conditions difficult to treat.
The best cure is prevention, says the U.S. Naval Hospital in Camp Pendleton, Cal. Here are five ways to help combat eating disorders:
Talk to your kids about natural differences in body shapes and sizes. Avoid negative attitudes or conversations about weight. Don't discourage activities, such as swimming or dancing, just because they draw attention to weight or body shape. Talk to your kids about the misguided way in which appearance is linked to success. Be a good role model by eating nutritious meals and exercising regularly.
Health Tip: Before You Have Lasik Surgery
Before you sign up for the vision-correcting procedure known as Lasik, make sure you have both the short view and the long view of how your vision will be affected.
The American Academy of Ophthalmology offers the following information:
Lasik may not give you perfect vision. Seven of 10 patients achieve 20/20 vision, but 20/20 doesn't always mean perfect vision. If you have Lasik to correct your distance vision, you'll still need reading glasses around age 45. The procedure is too new to know if there are any long-term ill effects beyond five years of surgery. Lasik can't be reversed. Most insurance doesn't cover the surgery.
