School cafeterias across America are going to look a little different this fall.
The USDA now says advertisements for unhealthy foods are no longer allowed.
One survey found 70 percent of students see ads for soda and junk food on vending machines and posters.
The USDA says banning them will help kids make healthier choices.
The agency had already made changes to school breakfast and lunch menus.
Schools will have to get rid of all unhealthy snacks as well as advertisements that don't meet healthy standards.
