抗老工程學

Scott

矽谷工程師 Scott 用第一性原理和工程師的類比,把血糖、膽固醇、脂肪酸、纖維、肌力訓練、皮膚抗老這些長壽科學,一集一個主題講到你徹底聽懂。不灌雞湯、不賣補品,只給你能自己判斷的核心原理。內容改編自粉專「矽谷工程師的抗衰老實驗室」的深度長文。

腸道菌下集(實作篇),接 EP7。你花錢買的益生菌膠囊,對健康人來說,大多幾天就被排掉了——像一批拿觀光簽證的過客。這集講清楚為什麼:你的原生菌群早就把腸道的生態位佔滿了(殖民化抵抗),外來菌很難住下來,所以對健康人日常補充,腸道多樣性和結構往往沒有可測量的改變。那什麼才有用?這集比較「發酵食物 vs 益生菌膠囊」的關鍵差別(發酵食物帶的是一整個生態系+代謝產物,不是單一菌株),講 Stanford 的 Wastyk 2021 Cell 隨機試驗(高發酵食物組菌相多樣性上升、發炎指標下降),並給... more

腸道菌上集(原理篇)。這集用工程師的比喻,把「腸道菌到底是什麼、幫你做什麼」一次講清楚。核心觀念:你的身體其實把大量代謝工作「外包」給腸道菌——人類基因組只有約 2 萬個蛋白質編碼基因,但你腸道菌加起來有約 330 萬個微生物基因,是你的 150 倍,所以它常被稱為你的「第二基因組」。你以為你在吃纖維,其實你是在餵這群菌,它們發酵後產出短鏈脂肪酸(尤其丁酸)回頭餵養你的腸道細胞、調節免疫——某種意義上,你吸收的是細菌的代謝產物。這集也講:為什麼菌相「多樣性」是健康指標、結腸裡的交叉餵養接力、腸腦... more

補充劑系列第一集。肌酸大概是市面上被研究最多、卻最常被冤枉的補充劑。這集從最根本講起:肌酸到底是什麼、吃進去怎麼在肌肉裡變成磷酸肌酸、又怎麼在你出力的頭幾秒鐘當「快充電池」供能;為什麼它對力量、肌肉量、甚至(證據還在累積的)大腦與抗疲勞都有幫助,證據等級各到哪。然後正面對決那個讓一堆人不敢吃的迷思——「肌酸會傷腎」:驗血報告上的肌酸酐(creatinine)升高,其實是肌酸代謝的正常產物變多,不等於腎功能變差;真正該怎麼看 eGFR、哪些人才需要謹慎,一次講清楚。Scott 也分享自己吃了十年的... more

糖系列外傳。你以為纖維都吃到腸子了?其實大部分在大腸前段就被細菌吃光,最容易出問題的遠端結腸長期挨餓。有一種東西撐得到那裡——抗性澱粉第三型(RS3):把澱粉煮熟、放涼冷藏,直鏈澱粉回凝成消化酶切不動的結晶,一路發酵到大腸遠端、產丁酸,餵飽你腸子最餓的那一段。這集把 RS 四型、大腸地理學、直鏈vs支鏈、糊化→回凝→再加熱的機制、丁酸的角色,用工程師的比喻講清楚,再給你 Scott 真的天天在做的兩招懶人實踐:①高直鏈澱粉的墨西哥黑豆,壓力鍋煮一批冰起來每天吃;②綠豆湯加甘胺酸,壓力鍋一杯綠豆六... more

糖的科學系列第四篇,也是行動篇。前三集講糖怎麼進身體、怎麼撞壞膠原蛋白、胰島素阻抗這台飛輪怎麼失控;這一集講「怎麼辦」。核心觀念:血糖跟膽固醇不一樣,不必越低越好、不必把糖戒到零,你要的是「管理水位」而不是「清空水庫」。Scott 跟 Emma 用治水工程的比喻,把血糖管理拆成四個槓桿加一個休息鍵:①降流速(進食順序、別吃裸體碳水、纖維、食物形態、GI/GL 的兩大限制)②飯後散步打開 GLUT4 後門③重量訓練把肌肉這座水庫蓋大④有氧主動排水⑤限時進食/斷食讓胰島素工頭定期下班,再加最根本的「... more

糖的科學系列第三篇,主角從「糖」換成「胰島素」。前兩集講糖怎麼進細胞、糖怎麼撞壞膠原蛋白;這一集講真正的能量總指揮——胰島素——失控之後,整個系統怎麼一起出事。Scott 跟 Emma 用工程師的比喻拆給你聽:胰島素其實是「儲存模式總開關」;胰島素阻抗不是單一指標紅字,是一台會自我加速的正回饋飛輪,有四個可怕特性(互相加重、長期隱形、越晚越難、瘦不保證安全);為什麼體檢全綠、血糖正常,飛輪可能已經轉了好幾年(HOMA-IR 才看得到);它下游牽動脂肪肝、高血壓、部分癌症、視網膜、多囊與痘痘,甚至... more

你臉上的皺紋、血管硬化、糖尿病腎病、視網膜病變——其實是同一個化學反應(糖化/AGE)在不同器官演的劇本。這集用工程師的邏輯,把血糖怎麼一步一步把你的膠原蛋白焊死講清楚。不灌雞湯、不賣補品,只給你能自己判斷的核心原理。 ▍想開始練?我做的免費 App「Soliday」:一天一個動作,App Store / Google Play 搜 Soliday。

你身邊有沒有那種「戒糖教」的朋友?這集我們不灌雞湯,直接從第一性原理出發,像 debug 程式碼一樣,把葡萄糖和果糖的底層差異、糖進身體之後怎麼跑、為什麼吃糖會變胖、為什麼會升壞膽固醇、脂肪肝是怎麼來的,一條一條講清楚。聽完你以後看任何飲食法,大腦裡都會有一個超清晰的骨架。 ▍想開始練?我做的免費 App「Soliday」:一天一個動作,App Store / Google Play 搜 Soliday。
