The National School Lunch Program was created to fight hunger and bad nutrition that existed during World War I. One-third of the young men called to be soldiers in World War I were turned down from service. This was due to poor nutrition-related problems such as being underweight. After the war, teachers, parents, doctors, and scientists began to fight poor nutrition in children. ‘Hot Lunch Clubs’ opened up all over the country to give healthy meals to schoolchildren. This program started as a volunteer-run school lunch program in the 1920s. However, in the 1930s, this program received public support and some state funding.
