Reading the edits, I just think OP is poop-shy and its either scared/ grossed out to poop on a camping trip, or has to use one of them "hole in the floor" toilets. At the end of the day, If OPs life is not on the line (which it doesn't sound as), its better to endure the poop than to endure whatever digestive torture they are about to inflict on themselves, but thats my opinion.
If it were something demanding like expedition to the everest they probably would have someone professional preparing them nad telling them what to and what not to eat.
