I think if we can count on Them to keep us alive and give us water, I don't think we're going to be kept where it's impossible to turn our ingredients into real, edible food. Food is also kind of important for our survival. They've never completely taken away our food, even when we were put in situations where we couldn't easily get to it, people got it eventually. The only exceptions are when smaller groups are hidden somewhere, but they almost always give us notes to look for them, so I think we'll be okay.
