Have you ever experimented with grinded meat, Iguana? I can´t eat much meat, even if it is grinded, so I cannot experiment with it. But when I pureed, for example, nuts, I could actually eat LESS of them as usually, the alliesthetic stops manifested earlier or at least clearer (maybe because the surface of the pureed food is larger?) and my digestion was more perfect, at least with some kinds of nuts. When I add salt to meat, avocado, vegetable etc., I can suddenly eat more of the respective food, because alliesthetic stops disappear, and this can have negative effects (in my case). But after extensive experimenting with pureeing food (because I wore fixed braces for one and a half years...) I think that there is no reason to "forbid" mechanical treatment of food on principle, as long as one doesn´t mix different foods together and doesn´t add condiments.
I bet the answer is no. What for since the guru told him? 
I’m actually doing the opposite experiment: to eat unprocessed meat and everything else unprocessed, unseasoned. My former 41 years experiment with ground, processed meat and other cooked foodstuff was disastrous enough… Yeah, I didn’t separate the variable and try each processed foodstuff and each process independently : it would be a painstakingly long work.
But I’ve recently experienced raw ground supermarket beef on my cat. He’s very found of it and he engulfs it very quickly in large amounts. On the opposite, he doesn’t like raw, plain supermarket beef at all: he reluctantly eats some when extremely hungry only.
I also witnessed the experiment of our friend “Carnivore” with his damned meat grinder doing the hell of a noise. He apparently ate so much meat and meat only during so long that in the end he grew tired, bored and lazy of chewing it. So, by grinding it, he could still easily eat exclusively meat for some more months.
Even if there was no grinders and blenders in the Paleolithoc era, I don’t think grinding food is too bad; in the case of someone missing teeth it can be the best solution to still eat raw. But if our natural grinder (our mouth with teeth) is in working order, why recourse to an external grinder? Of course, it’s not “forbidden” (everybody being free to eat and process whatever he or she likes). Everything has advantages and shortcoming, and so it is for grinding. The main shortcomings of grinding seem to me that we mix different parts of the stuff, some of these parts we might not have eaten when unprocessed so that we could eat the parts we like and reject the parts tasting bad. Per example, once meat is ground, we can no longer choose the ratio of fat to muscle because everything is mixed. If you grind carrots or make carrot juice, you cannot spit out and reject the possible bad one since it’ll be mixed with all the others.
In doubt, it may be wise to eliminate every plainly Neolithic food and processes: its’ just an elementary application of the precautionary principle. I didn’t write that there’s a
non-manifestation of the alliesthetic stop with ground food, Michael, I inserted “may” and “can” in my sentences.
As for
“gurus”, Alphagruis
, I had plenty of them and they taught me a lot of things, to start with my father and mother, school teachers, professors, philosophers, engineers, biologists and physicists. I owe them just about everything I know. Nevertheless, I put everything into questions and I avoid beliefs like the plague, as recommended by Descartes for example. But when an argument is logical and coherent, I don’t feel an irresistible need to put my life and health in danger by setting up experiments to prove or disprove it, especially when I don’t give a damn about it.
