I go back and forth on this myself. We do not live in the Paleolithic, and the best we can do, really, is mimic what we think they ate. We're never going to replicate it. It does seem that high fat all year round would have been unlikely, but who knows for sure? It also depends on how the fat is made. Personally, I have never been able to "stomach" big chunks of fat like others seem to crave.



Of course, as you'll find out, on this list there's going to be someone who has an issue with just about any food someone else eats. For some it's medical, for others philosophical (or, perhaps, "eccentric" :).

As I read this I was just finishing up some yoghurt made from raw milk with blueberries mixed in. Pretty tasty. I eat it because it causes me no issues, and I like it. Of course, I happen to be of Scandinavian descent, so I guess I'm a milk-mutant.



What seems to be glossed over so much on this list is the genetic drift our species has experienced over several millennia. Certainly the core of our diet should be meat (or fish or fowl); but with such a large (7 BILLION!) population base, we cannot just dismiss the variations in genes that have emerged. In my opinion, we are truly living in the "one man's fruit is another man's poison" age.
