Tons of Americans want to eat healthy but don't have the energy/time/access. It's easy to cook healthy for yourself if you're single, have a good work/life balance, and have a grocery store nearby. There are a lot of Americans who eat fast food on the go because it's their only option (or they haven't been educated on how to get healthy food quickly). Others have lives where job and family responsibilities sap so much energy that by dinner time ordering a pizza is pretty tempting.
