“In an age when consumers have become increasingly suspicious of processed food, the Internet has become a powerful platform for activists who want to hold Big Food accountable,” begins a story at the NPR blog The Salt about Vani Hari, known on the Web as Food Babe, “one of the highest-profile of these new food crusaders.” Hari was the driving force behind a petition that persuaded Kraft to get rid of artificial orange color in its mac and cheese, notes NPR. “Detractors, many of them academics, say she stokes unfounded fears about what’s in our food to garner publicity.” NPR quotes Hari’s comments in the Charlotte Observer, “I’m trying to help people understand things that no one else has spoken out about.”
