When Leanne Brown moved to New York from Canada to earn a master's in food studies at New York University, she couldn't help noticing that Americans on a tight budget were eating a lot of processed foods heavy in carbs.

"It really bothered me," she says. "The 47 million people on food stamps — and that's a big chunk of the population — don't have the same choices everyone else does."
