1850年：“糖尿病患者必须完全避免食用糖和淀粉。肉类和脂肪是安全的。”1900年：“糖尿病患者在症状消失前只能食用肉类、鸡蛋和黄油。”1920年：“糖尿病患者需要胰岛素，但仍应大幅限制碳水化合物的摄入。”1950年：“糖尿病患者如果注射足够的胰岛素，就可以适量食用碳水化合物。”1980年：“糖尿病患者应在均衡饮食中大量食用全谷物。”2025 年：“糖尿病患者每餐应摄入 45-60 克碳水化合物，并服用二甲双胍、胰岛素和 GLP-1 受体激动剂。”注意到其中的规律了吗？随着药品选择的增多，碳水化合物的推荐摄入量也随之增加。并非科学本身发生了改变，而是盈利模式发生了改变。几个世纪以来，维持糖尿病患者生命的治疗方法逐渐被能够产生持续收入的治疗方法所取代。你曾祖父的医生知道碳水化合物是问题所在。你的医生知道你只是个赚钱的工具。1850: "Diabetic patients must avoid sugar and starch entirely. Meat and fat are safe."1900: "Diabetic patients should eat only meat, eggs, and butter until symptoms resolve."1920: "Diabetic patients need insulin but should still restrict carbohydrates significantly."1950: "Diabetic patients can eat moderate carbs if they take enough insulin."1980: "Diabetic patients should eat plenty of whole grains as part of a balanced diet."2025: "Diabetic patients should eat 45-60g carbs per meal and take metformin, insulin, and GLP-1 agonists."Notice the pattern? As pharmaceutical options increased, carb recommendations increased.It's not that the science changed. It's that the profit model changed.The treatment that kept diabetics alive for centuries was progressively replaced by treatments that generate recurring revenue.Your great-great-grandfather's doctor knew carbs were the problem. Your doctor knows you're a revenue stream.
