My objections are the claims for it to be the *primal* diet.
The primal diet was incredibly varied, very seasonal, very site/area specific. It included so many things that (in our westernised, food rich society) we wouldn't even contemplate eating now.
Animal guts, and the contents, insect protein, small nestlings, (bones and all) rodents, amphibians and such like.
Grains are incredibly nutritious food, and his claims that corn isn't, is mince
The defining criteria is that we process our food. Corn needs to be processed to give full nutrition, so do oats, so do peas and rice. So does animal protein.
Cooking is the most basic processing that makes food digestible and much more calorifically valuable.
My intolerance of gluten is my issue, but then I can't digest milk properly either, or fish. I'm not a good example to use.
However, I find that I can manage an occasional gluten rich meal, much as I suspect the real 'primal' diet did. Then our ancestors found out how to gather grain and store then sow thickly to encourage heavier cropping, and they did it world wide with a huge range of plants.
Basically I'm saying there are *no* bad foods. Just that a surfeit of almost any of them isn't really good for us.
In our food abundant society though it's easy for us to be picky, to create new *diets*, as that fellow claims.
It's not 'primal' though, it's very modern, very much a chosen lifestyle.
My big bother's a Doctor, every one of them has an opinion.......much like us
