"Most the world cannot drink the stuff at all without getting sick,..."

I read a theory somewhere years ago that sharing milk may have caused relations between the Skraelings (Native Americans) and the Vikings to go south in the North America. The idea being that the Vikings gave the Indians milk and they, in turn, got sick and ultimately drove the Vikings out. I can't remember what evidence they could have based that theory on though...

Probably no evidence at all ~ but there were herd animals with surplus milk available and human beings had been tapping them for tens of thousands of years (having learned how to do that as infants even).

Almost all written evidence of the Viking colonization of America is from Snorri Sturlasson.

The story I remember is that a guy from Iceland went to America, built a hunting cabin with his crew, then came back and told people about it. Two crews went to his cabin, and surrounded by unclaimed wilderness and uncounted trees, decided to fight to the death over that one cabin already built (how Viking of them). The victors were not too pleased over their victory and there was ‘bad blood’ among them, and they went back to Iceland.

People have theorized that Christopher Columbus read Snorri Sturlasson, and thus knew of a land to the West - but after having read Snorri myself, I doubt it.
