Each day Roth gives 9-year-old Mason and 6-year-old Julia a piece of Tupperware to take with them to school. She calls it "the junk food collector." Whenever either of them is offered an item of food other than what's on the school's lunch menu, they are supposed to put it in the plastic container, take it home and have a discussion about whether or not it's fit to eat.
She sees it as a moment of empowerment and thinks it's necessary to protect her kids' health since people often give her children unauthorized snacks.
One day when Julia put a juice pop in her junk food collector, a teacher told her she couldn't do it because it would melt. The special treat was given because it was a hot day and the teacher said Julia could eat it or lose it. She lost.
But neither harsh criticism, social scorn nor a call to the police will deter Roth in her mission to fight obesity.
Roth's fervor to fight fat may be somewhat understandable given the rise in childhood obesity. The Centers for Disease Control and Prevention says 32 percent of children and 66 percent of adults are overweight or obese and the World Health Organization estimates 90 percent of women worldwide will be obese by 2030.
While some may see Roth's intentions as admirable or even noble, others think she's taken her food mission too far.
"What's a birthday if there's not some sort of treat?" questions parent David Jordan.
