The lawsuit - filed in New York State Supreme Court in the Bronx - says that McDonald's, Burger King, Wendy's and Kentucky Fried Chicken misled customers by enticing them with greasy, salty and sugary food.
I think what they're getting at is that these companies engaged in a fraud on the public, i.e., that the companies knew or had reason to know that their food was dangerous, portrayed it as healthy, the plaintiffs justifiably and actually relied on the fraud, and suffered damages as a result. What I'd like to know is: when did fast food restaurants ever portray their food as healthy? They sometimes claim that they're using vegetable oil in their food, but I'm not quite sure where the intentional fraud is.
