That article, in very cavalier terms, states that the researcher said. "“For many people today, the Paleolithic diet is a critical issue, not only with regard to the past, but also concerning the present and future. It is hard to convince a devout vegetarian that his/her ancestors were not vegetarians, and people tend to confuse personal beliefs with scientific reality.” It goes both ways, lots of folks are hung up on their meat.
The scientific reality would have people eating what is on hand and popular to them. If you live in abundance of sea food, or a land or time of more meat, or a steady easy supply of veggies, that is what people ate. People ate these thing with different results. Obviously, there is amongst these "speculators" a tendency to oversimplify human diet, or generalize in educated guesswork.
People lived off goat milk, weeds and berries, Think Alaska, fish and blubber. Think of all the knowledge passed down through generations about eating certain plants and their medicinal qualities. Think about the various masticating and chewing configurations that our unique mouths provide us. Think about the varieties of environments that our species has continued to evolve in, as it expanded territory. I doubt that there are absolutes and as usual, our bodies have amazing adaptive skills, that we are just realizing.
Ketosis would certainly come in handing during leaner cold winter times. We can do that, and I shouldn't think it particularly unhealthy, and I periodically fast myself. My system readjusts and after, I eat less, lose weight, am easier to get along with myself, the list goes on.
Bob, I have a question for you. Would you say that you find yourself eating less, or less glutenous, more easily satisfied now, than with processed food and carbs? I am satisfied eating less and my blood sugar is more stable. I enjoy my eating more, I address my food differently. I figure that it may be much to do with what we aren't eating, rather than what we are eating, when you and I change our diets in somewhat opposite ways from each other, but get so much of similar results.
This vegetarian will have a couple of bites of turkey this Thanksgiving. It will be a treat. My body can handle a bit of bird. If it were wild, I'd probably feel comfortable eating more of it. On the other hand, wild turkey probably doesn't melt in the mouth like a bred butterball.
Thank-you for two very interesting articles, but I do find some bias and incomplete information in significant parts of them both.
