Eating bugs is not only fucking disgusting it is not an optimal protein source. It is something we used to consume out of desperation in ancient times. The reason they're pushing it is so they can enjoy the good shit and leave the peasants to consume the slop they can mass produce for cheap. Being unable to digest such a thin part of it is probably(as far as I know) not a big deal however since that's how fiber works. It's one of the things that prevents you from having constant diarrhea.
