The document discusses promoting healthy eating in schools by only allowing healthy advertisements. It notes that obesity rates in children have tripled since food marketing began in schools in 1970.

Only supporting healthy ads would emphasize healthy eating, prepare students for healthy futures, and decrease obesity rates which correlate with marketing of unhealthy foods in schools.
