The US Department of Agriculture has introduced new nutrition standards that will require schools to add more fruits and vegetables to lunches served through the National School Lunch Program. The rules also set calorie limits and gradually reduce the amount of sodium and trans fat.
The Arizona Republic reports that the changes will be phased in over three years beginning July 1.
The new standards are part of a national focus on childhood obesity and the risk of high blood pressure, high cholesterol and type 2 diabetes.
The USDA also wanted to limit starchy vegetables to one cup a week but backed off after potato growers lobbied against it.
