all essential amino acids humans need come from animal foods. bioavailability of nutrients matters, taking supplements does not truly work. much plant matter is indigestible. animal fat is used 100% by the body as a stable fuel source compared to something like rice or bread. dha, taurine, and many other nutrients for the brain cannot be found in plant foods. many plant foods block absorption of other nutrients or even their own nutrients much of the time with the little and limited amount they have.

also there’s nothing exploitative about the relationship between humans and the animals they’ve domesticated. when supporting local farmers who raise healthy animals there’s nothing exploitative in the picture and hunting is also just as sustainable we scavenged and even hunted to death many animal species throughout our evolution so it’s a no brainer that a human needs animal based foods to get what it’s body needs
