But I'm trying to understand if there is an argument against casein in pure biochemical terms. OK some people here are intolerant to casein, but many people are not, so I don't see that supporting the idea that no-one should consume milk. And casein breaks down into an opioid peptide, and that could have opiate-type effects in the brain. But I read spinach also contains a compound that breaks down into an opioid peptide, so casein is not unique. And presumably the opiate effects will vary between different opioid peptides, with some having relatively little effect and being harmless.

Well, the opiod thing may harm some people, not everyone true. The histamine thing doesn't sound too good for anyone.
But even outside of that there's a lot of hormones in Cow milk that are far out of proportion to what a human (infant or adult) would get. At least, that is what Cordain argues in his newletter here: http://thepaleodiet.com/newsletter/...rierVol2No5.pdf
But would that be the case for goat or sheep milk? Maybe not so much.
