Do you know korean foods are really famous? We have our own diet.Resend it please and i just showed diet literally correlates with good facial development
<<In the ancestral health community, a lot of focus is placed on how the nutritional value of the human diet has changed since our days as hunter-gatherers, and how we can adjust our modern diet so it has a composition, macronutrient distribution, and micronutrient profile that more closely resemble that of ancestral human diets. Less attention is given to how the “hardness” of our diet has changed since the preagricultural era, and in which ways this might impact human health, growth, and development.
That’s not to say that nobody has been paying attention to this issue, as there has been some blog posts, presentations at conferences, and articles on this topic. However, in general, it’s safe to say that it’s definitely a subject that deserves more attention. Dr. Mike Mew, a London-based Orthodontist, estimates that modern humans use the masticatory system about 3-5% of what Paleolithic humans did, and that’s before you consider non-nutritional exercise of the jaws (i.e., using teeth as tools to make clothes and weapons) (1). 3-5%! That’s a big decline...
A common belief is that teeth alignment and development of the jaws are purely genetically determined. However, what we have to remember is that our genetic heritage isn’t the end all be all for how we are going to grow and develop. There’s a constant interaction between our genome and the environment, and the forces applied to structures during growth will affect how genes are expressed and the development of the size and shape of each structure.
In the same way that you won’t develop healthy and strong limbs if you’re not adequately stressing them through walking, running, and other physical activities during childhood, your jaws won’t grow correctly if you don’t stress them sufficiently from chewing. Chewing on hard, tough food is important because it activates bone cells in the tooth socket and promotes the growth of big and strong jaws in which there is adequate room for the third molars. There’s no doubt that our time spent running, walking, and otherwise moving our bodies has gone done dramatically since our days as hunter-gatherers. However, this reduction fades in comparison to the decline in masticatory effort and usage.
Soft diets cause dental arch abnormalities
Studies in many different animal species show that animals who are put on a diet of soft, processed food when they are young develop many of the same dental arch abnormalities as contemporary humans, such as malocclusion, narrowed dental arches, and crowded teeth (2, 3). One example is a study of hyraxes (relatives of elephants that chew like humans) fed nutritionally identical hard and soft diets. This study found that hyraxes raised on hard food developed jaws that were significantly longer, thicker, and wider than the ones who chewed softer food (4).
There is strong evidence to suggest that many of the same principles apply to our species as well. Studies – such as those carried out by researchers like Dr. Robert S. Corrucini, who campaigned the idea that malocclusion is a disease of civilization, and Dr. Weston A. Price, who documented the health condition of isolated, traditional populations before and after westernization – show that people who transition from a traditional lifestyle and nutrient-rich, whole foods diet to a western lifestyle and nutrient-poor, processed diet experience a rapid decline in health (5, 6). Moreover, there’s a high incidence of malocclusion, crowded teeth, and tooth decay among the children who are born and raised in the “westernized environment” (5, 6).
A study of younger Australian Aborigines whose families recently started eating processed, modern foods is one of the many examples of cases where these effects are seen. This study found that the younger family members had smaller jaws and serious tooth crowding problems compared to elder members of their families who grew up eating traditional food (5).
As for intervention trials, one small study that investigated theeffect of masticatory muscle training on facial growth in long-face children found that children who chewed on hard resinous gum for two hours each day for one year grew larger jaws and developed straighter teeth (7).
Besides reduced use of the masticatory system, other factors, in particular pacifier sucking, bottle-feeding, incorrect oral posture, and poor maternal and childhood nutritional status may also be important contributors to the high prevalence of malocclusion, crowded teeth, and narrow dental arches in westernized societies.
Shrinking faces
Hunter-gatherers and traditional, isolated people generally have broad dental arches, well-aligned teeth, and ample room for third molars (2, 6, 8). Moreover, examinations of fossils indicate that prior to the Agricultural Revolution, malocclusion and impacted wisdom teeth were virtually unheard of (2, 5, 8). This is in stark contrast to modern societies, where these conditions are extremely common.
In industrialized countries such as the U.S., approximately 50% of all wisdom teeth are removed and about 95% has deviations in their dental alignment (1). Of these 95%, some 30% are recommended orthodontics treatment, a treatment that improves the symptoms present, but may actually worsen the underlying problem (1).
Modern faces are “melting down” in the sense that there has been a major change in the human skeleton since the Paleolithic era. Over the last few thousand years – a blink of an eye from an evolutionary perspective – human faces have become approximately 5 to 10 % smaller after correcting for body size (2).
Some would argue that beauty is in the eye of the beholder and/or that culture is the main factor involved in determining what we perceive as aesthetically pleasing. However, we also have to remember that we have evolved an attraction to certain features as a way to distinguish the healthy and virile from the weak.
Physical attractiveness can serve as a biological signal of good health, and we probably find people with well-developed faces, strong jaws, and broad dental arches attractive because these features are indicators of good genetic qualities and health.
Besides being aesthetically unappealing, the change to a longer, thinner craniofacial structure has had important implications for how we breathe, chew, and function.>>
How the Western Diet Has Changed the Human Face
Most people know that children who grow up eating a processed, nutrient-poor diet are at increased risk of a wide range of medical problems, including obesity, type-2 diabetes, and hypertension. What is less known is that diet - particularly the diet you eat when you grow up - can have a major impacdarwinian-medicine.com
I have just shown western diets cause facial recession your literally not even willing to look at the other side that it might be epigenetics
+ if western diet causes recession how all the asians are much more recessed?
Tbh idk why I'm even talking about this. Just go out and see how asians look so different from whites...
