Re: Yes, it all starts to make sense
I find it very, very difficult to believe this. For one, I have heard of little to no legitimate studies done on this, even though the book that started the craze was on the NYT bestseller list. Nearly every source I consult shows significant evidence that this is based on questionable, incomplete, or (in some cases) a complete lack of evidence.
In addition, there's literally no remotely plausible way that any group of people should not eat significant amounts of meat. It's physically impossible to survive on grains (you die rather quickly of horrible deficiency syndromes) and attempting grains + beans isn't much better. It took our bodies a very long time to adapt to the diet they were at 10,000 years ago (up to 50 percent meat and over), and I don't think that these metabolic pathways could be so profoundly altered so easily. It would be a profound disadvantage for any human being to develop a significant intolerance/immune reaction to meat - such people would die young and be of poor health their whole lives, self-selecting themselves OUT of the gene pool.
The hormonal system (insulin mechanism in particular) of human .beings is also not suited to large amoutns of dietary carbohydrate.
Dairy is still highly allergenic to people that are tolerant of lactose and other potentially reactive (with your body) factors.
Grains and legumes are both literally types of starvation food. Grains always were treated this way prior to the advent of agriculture. Could you imagine what would drive someone to
eat grass seeds?
In addition, he heavily recommends soy. Talk about evolutionary discordance! Trying to survive on soy would be (slow) suicide with the sheer number of antinutritonal factors.
My two cents. :o) I'm B+, BTW, Irish/Scottish/British ancestry on one side, Russian and possibly German and/or Polish on the other. My true metabolism is naturally very, very high (amount of food I eat, high resting HR, speed and efficacy of enzymes, etc.) and I can manage significant amounts of carbohydrate in my diet somewhat well, but they don't tend to make me feel great, so I somewhat avoid carbohydrate, but really specifically just grains. Cutting dairy out made it so that I could actually almost breathe freely again.
