Medusa, Food Wars and Cupcake Wars are not about food fights. "Food Wars" is about two restaurants competing to say who makes the best "X" in "Y" - like the best Cheesesteak in Philadelphia or the best deep dish pizza in Chicago. And Cupcake wars does not involve throwing cupcakes, it is a competition with 4 different bakers to see who makes the best cupcakes. It's a 'reality' show, so there are different parameters each time, but it's not about throwing food.
