considering the natural sources, i would look at eskimos and maybe the japanese to compare colon cancer rates

Of course, Eskimos' traditional diet was very high in saturated fat, which is supposed to increase risk of colon cancer.

I think the story with the Eskimos is that their diet has traditionally been much of fish and animals that eat fish. That’s probably far less true today. In any case, you’d have to know their blood levels of vitamin D to make any judgment.
