I don't believe in evolution at all, but I don't think you have to believe in evolution to comprehend that Elaine Morgan is almost certainly correct in thinking that humans originally lived in water. We share about a hunded characteristics with the aquatic mammals and are totally without adaptation for life on land. That also says that the original human diet was some combination of shellfish and fruit i.e. stuff we could get our hands on quickly both along the shore and just off it and that, in particular, green vegetables were never a part of the human diet and are a totally unnatural thing for humans to eat.
The whole world knows that a little kid's basic reaction to alcohol and tobacco is correct; why would anybody think that same little kid's reaction to green veggies was wrong?? When something tastes that bad, your body is trying to tell you something.
I liked veggies as a kid. I think what kids do or don’t like often comes from a parent’s reaction.
I noticed that my ex wife and her kids didn’t like exactly the same things so I tried an experiment. I convinced her to make a big production of how much she liked brussells sprouts and sure enough the kids liked them too.
