Not to be outdone by her husband’s decrees.

The Obama administration laid out new restrictions on the marketing of junk food and sugary drinks in schools on Tuesday.

The new rules from the White House and the Department of Agriculture prohibit advertisements for unhealthy foods on school campuses during the school day, including sugary drinks that account for 90 percent of such ads in school. An ad for regular Coca-Cola, for example, would be banned from appearing on a scoreboard at a high school football game, though ads for Diet Coke and Dasani water, owned by the same company, would be allowed. Junk food ads like a Coca-Cola scoreboard would be phased out under the new rules and would not have to be replaced overnight.

“The idea here is simple—our classrooms should be healthy places where kids aren’t bombarded with ads for junk food,” First Lady Michelle Obama said in a statement.  “Because when parents are working hard to teach their kids healthy habits at home, their work shouldn’t be undone by unhealthy messages at school.”

Michelle Obama and Agriculture Secretary Tom Vilsak will announce the new regulations at a White House event Tuesday. The rules come as part of the first lady’s “Let’s Move” campaign to fight childhood obesity. Industry heavyweights like Coca-Cola and PepsiCo are backing the new regulations.
