蓝区:活到 100 岁比例高出 10 倍的地方
Blue Zones, where people reach age 100 at 10 times greater rates

导读
这篇论文梳理全球“蓝区”(Blue Zones)——百岁老人比例约为普通地区10倍——的共同生活方式与环境特征,如以植物性食物为主的饮食、适度饮酒、日常活动以及紧密的家庭和社区关系。它讨论这些因素如何与长寿相关,但作为观察性研究,难以证明单一饮食或生活方式的因果作用。
HN 关注点:蓝区长寿叙事是否经得起推敲:撒丁岛牧羊人实际吃肉、年龄记录可靠性、贫困与社区/宗教等混杂因素,以及轶事如何被包装成饮食结论。

这几条评论里:质疑 2 补充 2
质疑撒丁岛百岁老人多为牧羊人,实际动物蛋白/脂肪摄入更高,反驳“素食长寿”叙事。
谈到撒丁岛时,他们总说当地饮食以素食为主……但事实上,百岁老人多集中在牧羊人群体,而牧羊人摄入的动物蛋白和脂肪比其他人更多。因为多数人不懂意大利语,这种说法可以一直维持;但那些小镇的人受访时总说他们并非素食者。视频里102岁的Graziano被问是否因遵循地中海饮食而长寿,他反问“那是什么?”并说“蔬菜对你有害,我吃了100只羊的草,因为我吃了羊”,他实际上只吃肉。这说明整个饮食说法需要重新核查。

When speaking about Sardinia they keep saying that their diet was mostly vegetarian: "The classic Sardinian diet is plant based, consisting of whole-grain bread, beans, garden vegetables, and fruits. Meat is largely reserved for Sundays and special occasions. Sardinians drink wine moderately." Truth is that the Shepherds (the centenaries are mostly found in this group) were actually eating more animal protein and fat compared to the rest of the population. https://snipboard.io/gbi9JY.jpg They can keep lying to most people just because you can't understand Italian but whenever people from those towns are interviewed they always repeat that they were not vegetarians. Here a quick translation from this yt video: Graziano who got to 102 got asked if he got to 102yo because he had always followed a mediterranean diet. He asked what's that? It means that you always ate vegetables. Vegetables are bad for you, I ate the grass of 100 sheeps because I ate the sheeps. And indeed he only ate meat, meaning that this whole alimentation thing should be checked again. https://youtu.be/LQTocSMm7tw?t=647
补充蓝区年龄记录可能可靠;更关键是贫困、自给饮食和社区满足感等生活方式,而非单纯饮食配方。
我读过这两本书且很喜欢。针对常见质疑:作者称所有蓝区的年龄都用历史上的市政出生记录核实过。我无法判断具体地区,但我自己做家谱研究时,对19世纪西西里市政和天主教会记录的普遍与详细程度感到震惊;统一前的意大利受多个北欧国家统治,记录标准受其影响。不能说这适用于书中所有国家,但记录老不等于记录差。书中一个少被讨论的点是:除Loma Linda外,蓝区都很贫穷,人们主要吃自己种或采的食物,这出于必要反而促成简单稳定的饮食;生活规律简单,靠社区、家庭和朋友获得满足,安于所有、不追求更多。我觉得书很启发人,即使不能让我活到100,按更接近蓝区的饮食让我感觉更好并减重。

I read the books and enjoyed them. - To respond to one criticism seen widely here, the authors claim to have validated ages with historical municipal birth records in all the Blue Zones. I cannot speak to these particular zones, but I've been doing genealogical research on my own ancestry and I am absolutely blown away by the ubiquity and detail of both municipal and Catholic church records in Sicily in the 1800s. Preunification Italy was under the rule of various northern European countries and was heavily influenced by their standards of record keeping. I cannot say if this applies to the other countries in the book, but generally speaking, just because these records are old doesn't mean they are bad. - One thing that was very notable in the books but isn't discussed very much is that, with the exception of the Loma Linda cohort, the Blue Zone areas are all quite poor. They all primarily eat food they are able to grow or harvest themselves, out of necessity, which encourages simple and consistent diets. They have routine, simple lives that are made fulfilling by concentrating on community, family, and friends. They are content with what little they have and do not strive for more than they need. I found the books quite inspiring. I think the lessons learned are good, even if they won't get me to 100. In any case I've felt much better and lost weight on a closer-to-Blue-Zone diet than I did before.
质疑用伊卡里亚个例说明蓝区叙事像轶事/幸存者偏差,削弱可信度。
有一位伊卡里亚人Stamatis Moraitis,22岁去美国追梦,做画家并很快成功,买房结婚生3个孩子。66岁被诊断晚期肺癌。他决定不在美国等死,回伊卡里亚与父母住,开始呼吸那里空气、喝葡萄酒、吃地中海饮食。几个月后他种了个园子,本没打算能收获;37年后,他的葡萄园每年产200升葡萄酒。他的秘诀是“我只是忘了死。”我认为这正是文章可信度大打折扣的地方。

One Ikarian in particular, Stamatis Moraitis, moved to America when he was 22 years old to pursue the American dream. He was a painter, and immediately started having success, bought a house, married, and had 3 kids. At the age of 66 years, he developed terminal lung cancer. Instead of dying in America, he decided to move back to Ikaria and moved in with his parents. He started breathing the air, drinking the wine, and eating a Mediterranean diet. After a few months, he planted a garden not planning on ever getting to harvest the vegetables; 37 years later he has a vineyard producing 200 L of wine a year. His secret he says? “I just forgot to die.” This is where I think the article loses its credibility significantly.
补充Loma Linda的长寿可能来自宗教社区健康规范与医疗资源,不能简单归因于蓝区饮食。
我在南加州洛杉矶以东60英里的Loma Linda住过几年,那里是蓝区之一。当地主要是基督复临安息日会社区,显著特点是重视健康生活方式,通常素食,并避免酒精、咖啡因等。城里还有大型医学院和医院综合体,很多居民在医疗行业工作。当然还有很多其他解释。

I lived in Loma Linda for a few years (in Southern California, 60 miles east of LA), which is one of the blue zones It is predominantly a 7th day Adventist community. Notably they prioritize healthy lifestyle and typically are vegetarian as well as avoiding alcohol, caffeine, etc. There is also a big medical school and hospital complex in the city and many people that live there work in the healthcare field. There are of course plenty of other explanations.
