WASHINGTON-School lunches have been called many things, but a group of retired military officers is giving them a new label: national security threat.
That's not a reference to the mystery meat served up in the cafeteria line either. The retired officers are saying that school lunches have helped make the nation's young people so fat that fewer of them can meet the military's physical fitness standards, and recruitment will be difficult.
A new report being released Tuesday says more than 9 million young adults, or 27 percent of all Americans ages 17 to 24, are too overweight to join the military. Now, the officers are advocating for passage of a wide?ranging nutrition bill that aims to make the nation's school lunches healthier.
The military group acknowledges that other things keep young adults out of the armed services, such as a criminal record or the lack of a high school diploma. But weight problems that have worsened over the past 15 years are now the leading medical reason that recruits are rejected.
Although all branches of the military now meet or exceed recruitment goals, retired Navy Rear Adm. James Barnett Jr., a member of the officers group, says the obesity trend could affect that.
“When over a quarter of young adults are too fat to fight, we need to take notice，” Barnett said. He noted that national security in the year 2030 is “absolutely dependent” on reversing child obesity rates.
This isn't the first time the military has gotten involved in the debate over school lunches. During World War Ⅱ， military leaders had the opposite problem, reporting that many recruits were rejected because of stunted growth and inadequate nutrition. After the war, military leaders pushed Congress to establish the national school lunch program so children would grow up healthier.
Today, the group is urging Congress to eliminate junk food and high?calorie beverages from schools, put more money into the school lunch program and develop new strategies that help children develop healthier habits
