I would assume that, for apocalypse purposes, these kinds of supplies aren't meant as a long-term meal solution so much as a supplemental or "bridge" food source to use while you work on establishing a new food supply? In which case convenience and shelf stability probably is more important than hitting an optimal nutrient profile for long-term health.
