“When deciding what to pack, parents are juggling time, cost, convenience, and what is acceptable to their children. Unfortunately, these factors are not always in harmony with good nutrition,” the senior author of the study, Jeanne Goldberg, said in a press release.
The researchers used digital photography to document the lunches and snacks of more than 600 Massachusetts third- and fourth-graders in 12 schools in six public school districts. Only 27 percent of the lunches met at least three of the five National School Lunch Program standards, and only 4 percent of the snacks met at least two of the four Child and Adult Food Care Program standards. Both emphasize fruits, vegetables, whole grains and low- or non-fat dairy products.
Most of the lunches had pre-packaged snack or dessert foods, and almost 25 percent lacked what would be considered an entrée, like a sandwich. The study also found that the snacks children packed were not nutritious, with most including sugar-sweetened beverages.
“The few existing studies on packed lunches report that children who bring their lunch tend to consume fewer fruits and vegetables, less fiber and more total calories than those who participate in the National School Lunch Program,” Goldberg said.
Goldberg and her colleagues acknowledged that larger studies of more diverse groups of students over an extended period of time are needed, they say their study points to the need to help parents pack more nutritious lunches.
You can use the Choosemyplate.gov diagram as a starting point for a healthy lunch. Half the lunch should be fruits and vegetables, half of the grains should be whole grains, and dairy items should be low-fat or fat-free. It’s also important to make sure portion sizes are appropriate, and the American Academy of Pediatrics recommends water, not sugary drinks.
“Given that over 40 percent of U.S. schoolchildren bring their lunches to school on a given day, it’s important to consider how nutrition experts and policymakers could help parents meet the challenges of cost, convenience, and child preference and add nutrition to the equation,” Goldberg said.
