So, what was the conclusion about this in the end? Having read the full thread it just seems to leave it unanswered. I have read both the Paleo diet and the blood group diet and as a blood group B I am supposed to be able to tolerate dairy because the Bs migrated later on in the timeline and were the first people to actually milk their animals. Confusing when Paleo states that no dairy is allowed because no Paleolithic person would have been able to milk an animal even if they were able to catch it alive(!)and therefore it is unatural for the human body to ingest it. Help!!
