1968年：美国心脏协会建议每周鸡蛋摄入量限制在3个以内。为什么？鸡蛋含有200毫克胆固醇。人们曾认为膳食胆固醇会升高血液胆固醇（事实并非如此）。因此，人们认为鸡蛋会导致心脏病（事实也并非如此）。餐馆从菜单中移除了鸡蛋。人们不再食用早餐主食。蛋清粉（只用蛋白制成）开始流行。与此同时，相关研究也在不断积累：一项又一项研究表明，对于大多数人来说，膳食胆固醇对血液胆固醇的影响微乎其微。你的肝脏每天产生 1000-1400 毫克，并根据摄入量调节产量。从鸡蛋中摄取200毫克钙几乎感觉不到。但这些准则依然存在。40年的鸡蛋恐慌。2015年：膳食指南最终取消了胆固醇限制。没有大张旗鼓，没有承认错误，只有悄悄的修改。“总胆固醇不再是需要关注的指标。”翻译：“我们对自然界营养最丰富的食物之一的看法，在过去40年里犯了灾难性的错误。哎呀。言归正传。”鸡蛋恐慌造成的损失：两代人都在回避完美的食物公众对营养科学的信任40年来，人们一直用蛋清代替鸡蛋。我们获得了什么？什么也没发生。心脏病发病率继续攀升。鸡蛋恐慌的起因是：- 胆固醇假说存在缺陷对膳食胆固醇与血液胆固醇的误解- 行业游说反对鸡蛋（谷物行业从中受益）政策制定后的制度动力鸡蛋在2015年被证明无罪。但大多数人似乎并不知道这件事。他们仍然吃蛋白煎蛋卷，不吃蛋黄。因为他们记得“鸡蛋不好”，却错过了“其实没关系”这句话。你奶奶每天都吃鸡蛋，活到了90岁。专家建议你40年内避免食用它们。谁是对的？1968: American Heart Association recommends limiting eggs to 3 per week.Why? Eggs contain 200mg cholesterol. Dietary cholesterol was assumed to raise blood cholesterol (it doesn't). Therefore eggs cause heart disease (they don't).Restaurants removed eggs from menus. People stopped eating breakfast staples. Egg Beaters (egg whites only) became popular.Meanwhile, research was accumulating:Study after study showed dietary cholesterol has minimal impact on blood cholesterol for most people. Your liver produces 1000-1400mg daily and adjusts production based on intake.Eating 200mg from eggs barely registers.But the guidelines remained. 40 years of egg panic.2015: Dietary guidelines finally remove cholesterol limits.No fanfare. No admission of error. Just quiet revision."Total cholesterol is no longer a marker of concern."Translation: "We were catastrophically wrong for 40 years about one of nature's most nutrient-dense foods. Oops. Moving on."The egg panic cost:- Two generations avoiding a perfect food- Public trust in nutritional science- 40 years of people eating Egg Beaters instead of eggsWhat did we gain?Nothing. Heart disease rates continued climbing.The egg panic was based on:- Flawed cholesterol hypothesis- Misunderstanding of dietary vs blood cholesterol- Industry lobbying against eggs (cereal industry benefited)- Institutional momentum once policy was setEggs were exonerated in 2015. Most people never got the memo.They're still eating egg white omelets and avoiding yolks. Because they remember "eggs are bad" but missed "actually never mind."Your grandmother ate eggs daily and lived to 90.Experts told you to avoid them for 40 years.Who was right?
