A Frito-Lay spokeswoman, quoted in the Washington Post:
For Frito-Lay, a focus on real ingredients is a new way to help consumers overcome their guilt about eating snack chips. Last year, the company redesigned the back panels of bags of Lay’s potato chips, Tostitos tortilla chips and Fritos.
The Lay’s bag shows a pile of fresh potatoes. On Tostitos’ bag, an ear of corn has the husk pulled back to show it filled with corn chips. “It’s anecdotal, but we’ve had people tell us that they didn’t know there were potatoes in potato chips,” Gonzalez said. “What it is trying to reinforce is our agricultural base. People forget corn chips come from corn.”
