About 30 million school kids qualify for free or low-cost school lunches through the National School Lunch Program. A dozen years ago a federal law tightened school lunch nutritional requirements with the Healthy, Hunger-Free Kids Act. The federal law hoped to increase school kids intake of vegetables, fruits, fiber, grains and unsweetened beverages. The federal initiative was in response to findings that children who got free lunches were gaining more weight than higher income children not in the program. Prior to the tightened federal standards, low-income children enrolled in the school lunch program were more likely to have a body mass index closer to the obesity threshold than their higher-income peers. Rather than alleviate hunger, there was concern that the school lunch program was contributing to childhood obesity. According to the CDC, 21% of kids age 6 to 11 are obese, while 17% of adolescents age 12 to 19 are obese. Nearly 10% have severe obesity.
