1930 年代：加拿大牙医韦斯顿·A·普莱斯博士在他的诊疗过程中发现了一些令人不安的事情。儿童的面容正在发生变化。腭部变窄。牙齿拥挤。智齿阻生。面部结构与父母那一代人明显不同。这不是几个世纪以来的渐进变化，而是在一代人的时间内发生的。普莱斯展开调查。他花了十年时间走访现代食物尚未普及到的偏远地区。瑞士阿尔卑斯山村庄：食用生牛奶、奶酪、黑麦面包，偶尔也吃肉。牙齿完美。脸型宽阔。零蛀牙。骨骼结构强健。外赫布里底群岛的盖尔语社区：以鱼、燕麦和少量蔬菜为食。牙齿排列整齐，没有拥挤。骨骼强健。澳大利亚原住民：食用海鲜、袋鼠和野生动物。牙齿完美。面部宽阔。无牙齿畸形。非洲部落：食用牛血、牛奶和牛肉。牙齿完美。脸型宽阔。零蛀牙。因纽特人：以海豹、鱼类和驯鹿为食。牙齿完美。牙弓宽阔。没有智齿阻生。太平洋岛民：食用海鲜、猪肉和椰子。牙齿完美。骨骼强健。所有与世隔绝的人群：牙齿健康状况良好。脸型宽阔。骨骼发育正常。10 年后，西方食品传入这些社区，普莱斯再次回到这些社区。那些食用传统饮食的成年人：仍然拥有完美的牙齿。他们的孩子吃面粉、糖和罐头食品：脸型狭窄，牙齿拥挤，蛀牙，骨骼畸形。普莱斯拍下了照片。证据是照片，而不是轶事。相同的基因，不同的营养，一代人之间却呈现出截然不同的面部结构。传统上，人们食用的食物造就了宽阔的脸庞和完美的牙齿：动物制品，特别是动物内脏和生乳制品。导致脸型变窄、牙齿拥挤的现代食品：面粉、糖、精制谷物、植物油。这并非渐进式的基因变化，而是一代人之内对营养变化的发育性反应。普莱斯于1939年出版了这本书：《营养与身体退化》。共500页，包含数千张照片。现代正畸学的出现是因为我们改变了饮食习惯。食用祖先食物的传统人群不需要戴牙套。你的上颚狭窄和牙齿拥挤并非遗传因素造成的，而是营养不良导致的。你的父母在怀孕和童年时期都吃加工食品。你的面部结构就是对这种营养状况的适应。Price研究的传统人群：正畸问题为零。零。现代人食用加工过的谷物和种子油：正畸治疗已成为常规。我们已经将畸形正常化，并将矫正治疗医疗化，而不是解决其根本原因。普莱斯85年前就证明了这一点。医学院不教这个。正畸医生也因为不提及这一点而获利。面部结构由饮食决定。1930s: Dr. Weston A. Price, Canadian dentist, observes something disturbing in his practice.Children's faces are changing. Narrower palates. Crowded teeth. Impacted wisdom teeth. Facial structure noticeably different from their parents' generation.This isn't gradual change over centuries. This is happening in one generation.Price investigates. He spends 10 years traveling to isolated populations before modern food reaches them.Swiss Alpine villages: Eating raw milk, cheese, rye bread, and occasional meat. Perfect teeth. Broad faces. Zero cavities. Robust skeletal structure.Gaelic communities in Outer Hebrides: Eating fish, oats, and limited vegetables. Perfect dental arches. No crowding. Strong bones.Australian Aboriginals: Eating seafood, kangaroo, and foraged animals. Perfect teeth. Broad facial structure. No dental deformities.African tribes: Eating cattle blood, milk, and meat. Perfect teeth. Broad faces. Zero cavities.Inuit: Eating seal, fish, and caribou. Perfect teeth. Wide dental arches. No wisdom tooth impaction.Pacific Islanders: Eating seafood, pork, and coconuts. Perfect teeth. Robust skeletal structure.Every isolated population: Perfect dental health. Broad faces. Proper skeletal development.Then Price returns to these same communities 10 years later after Western foods arrive.The adults who ate traditional diets: Still have perfect teeth.Their children eating flour, sugar, and canned goods: Narrow faces. Crowded teeth. Dental cavities. Skeletal deformities.Price photographs this. The evidence is photographic, not anecdotal.Same genetics. Different nutrition. Completely different facial structure in one generation.The traditional foods that created broad faces and perfect teeth: Animal products, particularly organ meats and raw dairy.The modern foods that created narrow faces and crowded teeth: Flour, sugar, refined grains, seed oils.This wasn't gradual genetic change. This was developmental response to nutritional change within one generation.Price published this in 1939: "Nutrition and Physical Degeneration." 500 pages. Thousands of photographs.Modern orthodontics exist because we changed the diet. Traditional populations eating ancestral foods didn't need braces.Your narrow palate and crowded teeth aren't genetic. They're nutritional.Your parents ate processed food during pregnancy and childhood. Your facial structure developed in response to that nutrition.The traditional populations Price studied: Zero orthodontic problems. Zero.Modern populations eating processed grains and seed oils: Orthodontics is routine.We've normalised the deformity and medicalised the correction instead of addressing the cause.Price proved this 85 years ago. Medical schools don't teach it. Orthodontists profit from not mentioning it.Facial structure is determined by diet.
