In what context are you talking about? If say, there was only one super food you could eat and had all the nutrients you needed, I would say cheese, but if, the way I read it, is a food will mutant and take over the world, killing or enslaving humans.. they its definately Tomatoes.. I know RM wishes it where the other.. although wouldnt you be afraid of a 6 foot Banana trying to take a bite out of YOU RM?
