You may wish to remind your husband that for all intents and purposes human flesh is not kosher, per Shulchan Aruch 79:1 in the haga at the end.* While there may be a rishon who disagrees as is noted there, according to the Rambam there is an issur d’oraisa, and it is derived from a mitzvas asei.
Human blood is a different story. That is technically permitted if not for an issue of mar’is ayin. I blogged about that once.
