I just came across a remarkable audio file on this interesting subject, which I'll post in a minute.
But I'll set the scene first.
It would probably be otiose to include extensive comments on, and links to writing by, Weston Price on this subject, since that's been done here before. I'll just note in passing, for the sake of anyone that doesn't know, that Price travelled the world, visiting remote peoples and looking at their teeth. These people, when still eating their traditional diets generally had very good dental health -- in some cases, individual after individual had perfect teeth with no dental caries. In addition to this, their faces tended to be better formed than those of industrialised populations, so that they had no dental crowding and no deformations of the dental arch. None of their wisdom teeth were impacted -- which is very rare nowadays. Price also commented on other problems that seemed to be associated with this narrowing of the face, such as breathing problems and poor eyesight. He also reviewed explanations that people -- those who'd even thought about the problem at all -- had provided for the ill-fitting teeth of modern populations. These were, not to put too fine a point on it, darn silly. (You will still hear them, though.) Price intellectually demolished these explanations. He suggested, plausibly, that it was a matter of improper bone-growth and that the proper bone-growth would only take place when there was a good supply of the fat-soluble vitamins A, D and K in the diet and a whopping load of minerals. He was particularly impressed by the Maori, who had a high seafood diet that was very rich in the necessary nutrients; but others, including the people living in the Hebrides, had perfect dentition, too.
Right. So here are some more resources. First, a article at the WAPF "is it Mental or is it Dental?" that delves into the widespread consequences, including mental conditions, that have a link with poor facial structure. (The audio file I'm going to post also goes into this.)
Is it Mental or is it Dental? - Weston A Price Foundation
Note also that close observer and keen thinker Vilhjálmur Stefánsson, as so often, was in on this early even though he didn't get very far:
http://owndoc.com/pdf/The-fat-of-the-land.pdfAmong the human skeletons housed in the Peabody Museum of Harvard University, I found a sizeable lot of re- mains dug up by Stefansson and Hastings in 1905 from certain mediaeval cemeteries in Iceland. I was immediately fascinated by these Icelandic skulls, because of the perfection of their teeth and because they showed certain other features —palatine and mandibular tori, thickened tympanic plates, gable-shaped vaults—that were strongly reminiscent of Eskimo crania. Were these "Eskimoid" features the effect of a meat diet, of the Icelandic environment in general, or of an adulteration of Icelandic blood with that of Eskimo through the colonization of Greenland? I wrote an article on that subject in 1918, but even now I do not know the answer.
As the final piece of scene-setting, I think it's significant that the great American painter George Catlin was kind of aware of the problem. Catlin was, of course, another careful and thoughtful observer: indeed, an excellent amateur ethnographer. Catlin knew that North American Indian teeth were perfect, and commented on whites raiding Indian burial sites to steal teeth to make into false-teeth. He also comments, which I hadn't known, that an Indian name for whites (besides palefaces) was "the black teeth". Makes you think. And he noticed facial abnormalities in the American population even of that day and drew them. Catlin got the causality wrong, but at least he noticed things. See the drawing on page 30:
And, as a point of comparison, compare the strong jaw (and wide nostrils) of the comedian Tommy Cooper:
Now the audio file I promised:
Fourth one down -- "Facial structure and anxiety". It's fascinating. This lady goes into some of the ground covered in the WAPF "Is it mental or is it dental?" article. She also details a range of physical problems she had. Now here's the interesting bit: she was prescribed a dental appliance to wear by a holistic dentist that gradually eases the jaw open a little, taking the pressure off -- the reverse of the normal "brace" that pulls everything in. Not only did she have decreased anxiety and headaches; she also found that a hip that had been higher than the other started to drop, a slight degree of scoliosis began to go, and -- this is wild -- her toes which had been curled up began to straighten.
Now I've done a bit of Alexander Technique and so am well aware of how everything affects everything else, but even I was surprised.
What can you say? Who could think that orthodontists, using improper methods to correct a problem that unbeknownst to them is caused by improper nutrition, can (indirectly) pull someone's whole body out of shape? But that's what these results seem to imply.
The lady is a wonderful speaker and an obviously warm and energetic person who notices things and thinks about them. She seems to gets a little confused here and there -- e.g., when talking about the peptides from gluten -- but who cares? She knows practically what to do about gluten-intolerance, and she's demonstrated plenty of intelligence and persistence in the main issue here.
She's also written about her experiences:
Great find, as usual!
In my case, Vitamin D deficiency (and probably other malnutrition)led to a too small jaw and resulting extractions of permanent teeth as a child. Best they could do at the time.
My mother's taste for canned salmon & sardines helped me avoid any mental issues and may have contributed to a higher than average IQ test result.
