@asokel i dont think so, but you wont get any nutrition from it, it would be like those sea turtles that eat plastic, and then starve because they actually have stuff in their stomach and dont eat
@asokel the mres are deigned for war, to give someone everythign they need to survive in a protable and hard to damage package, they might not be nice but they definitely are actually good for you in terms of nutrition
@asokel well high quality is more a "best before" thing that "expires after", you can eat a cake that has been sitting around to the point its gone a bit stale without health consequences, but its best before that happens
