Yeah, this sounds like typical carnist propaganda. Meat has some magical ingredient needed for health that no one can name? Almost all peer-reviewed studies show that vegans (diet done properly) are the only group within healthy range for almost all markers; most meat eaters are deficient in B12 etc etc. It is strikingly similar to smoking: educating the public takes a very long time, laws are always behind and good news about your bad habits become industry-funded public "knowledge". Maybe we will have figured out how not to kill ourselves by the time we colonize mars
