The obesity epidemic is being fueled still further by a growing trend among kids to eat out and bring takeout food home, University of NorthCarolina researchers say. Such foods are high in sugar and calories, and their increasing popularity means youngsters are getting more calories than they need, the researchers note

D、
Since 1994, this trend has been growing rapidly and reflects the availability of fast food restaurants and foods prepared in supermarkets and other food stores, the researchers say. In fact, calories eaten away from home increased from 23.4% to 33.9% between 1977 and 2006.
"We found that kids eat a relatively maintained level of calories at home, but in addition kids also eat an increasing number of calories outside the home," says study author Jennifer Poti, from the university’s Gillings School of Global Public Health. "Eating outside the home is actually fueling the increased energy intake for kids." Poti says much of the foods children eat outside the home come from prepared meals sold in supermarkets and convenience stores, as well as fast food restaurants. Much of the fast food that children eat is actually consumed at home, Poti sai
D、In 2006, almost half of the fast foods children ate were eaten at home, she note
D、
Although the reasons for this increase in eating prepared meals isn’t known, Poti speculates it’s a combination of factors including convenience, cost and time pressures.
This trend is adding to the obesity epidemic, Poti says. "Parents need to be interested in both the food source and location where it is eaten, which both significantly influence energy intake," she says.
The report is published in theAugust issue of the Journal of theAmericanDieteticAssociation. For the study, Poti’s team collected data on 29,217 children ages 2 to 18. They had taken part in Nationwide FoodConsumption Survey, theContinuing Survey of Food Intakes by Individuals or one of another two nationally representative surveys of food intake in the United States. These surveys collected data at different times from 1977 to 2006, the study note

The researchers found that from 1977 to 2006, the number of calories children got from foods eaten away from home increased significantly. In fact, the percentage of calories children got from fast food was greater than those they got at school.
Samantha Heller, a dietitian, nutritionist, exercise physiologist and clinical nutrition coordinator at theCenter forCancerCare at Griffin Hospital inDerby,Conn., says that "in our fast-paced, time-challenged world, parents are convinced that it is easier and less expensive to eat takeout, fast food and in restaurants." Unfortunately, these foods are usually high in sodium, fat, sugar and calories, and low in healthy nutrients, she says, "We cannot control where these eateries are located or how they prepare their foods, but we can decide to cook more at home, which will ultimately save money and help keep our families healthy. More important, research suggests that family meals enhance the health and well-being of children on many levels.\
