There's an Open Source food replacement drink that's called Soylent. This is not a joke. Yes, there's a movie called Soylent Green in which the solution to the food shortages was a product for people to eat that was made from (presumably dead) people. I'm not sure I want to post a link to it because I might write a post about it. Also, I don't want to give the impression that I endorse the idea. But you're welcome to search for it.
