The idea that Tostitos now sells "Artisanal" chips is laughable, sure, but it turns out that another claim Frito-Lay likes to make on its packaging may end up costing it. The company has been hit with a class action lawsuit for claiming its chips are "all-natural." Whoops!

According to the suit brought forth by Milberg LLP, Frito-Lay is misleading consumers who buy its Tostitos and SunChips thinking that "made with all-natural ingredients" means ALL natural. Because, y'know, those chips that last years on the shelf contain "genetically modified corn and vegetable oils."

"The reasonable consumer assumes that seeds created by swapping genetic material across species to exhibit traits not naturally theirs are not 'all natural'" the suit says [PDF]. Of course, the suit has a bit of an upward battle in the States, because the FDA, which regulates these things, hasn't exactly come out to say that GM foods are not natural. In 1993, however, it issued a regulation that said it isn't misleading to call something "all-natural" when "nothing artificial or synthetic (including color additives regardless of source) has been included in, or has been added to, a food that would not normally be expected to be in the food." Wait, does that mean turduckens aren't natural?
