This PSA is about kids not resorting to food for comfort when they are hurt or upset. More importantly, it tells parents not to give food to their children but instead give them a hug.
The rate of childhood obesity in the 1980's compared to now? According to the CDC:
"Among preschool children aged 2–5, obesity increased from 5.0% to 10.4% between 1976–1980 and 2007–2008 and from 6.5% to 19.6% among those aged 6–11. Among adolescents aged 12–19, obesity increased from 5.0% to 18.1% during the same period. "
I think they need to start airing these PSA's again! I loved them when I was a kid. I am pretty sure they are the reason I didn't start smoking crack and why I love wagon wheels.
