American children should get more fruits, vegetables and whole grains in their school meals even though this will push up costs, a panel says.
As obesity among adolescents continues to rise, a report from the Institute of Medicine proposed a limited amount of calories and updating school meal programmers to meet nutritional needs and foster better eating habits.
However, the group recognized healthier, fresher ingredients would boost costs, especially at breakfast where fruit servings would increase. It estimated the changes could increase the cost of breakfast by as much as 25 per cent and lunch by 9 percent.
Many school canteens serve such fare as hot dogs, chicken nuggets and French fries, while there is a shortage of fresh produce. Under the new guidelines, most school food providers would need more government money to help pay for food, training and equipment, the report said. “This will be a very wise investment in children’s health,” said Virginia Stallings, chair of the group that conducted the study.
School meal programmers provide more than half of students’ food and nutrient intake during the school day.
“Today overweight children outnumber undernourished children, and childhood obesity is often referred to as an epidemic in both the medical and community settings,” Stallings wrote in the report. Obesity rates among American children have doubled in the past 20 years, and almost a third of American are either overweight or obese. Obesity is linked to health problems, such as heart disease, diabetes and cancer.
The report also backed a gradual lowering of sodium levels during the next 10 years and more whole grains in school meals. In addition, it proposed serving more fruit, with no more than half of it as juice, and favored more servings of leafy vegetables.
