喝牛奶會生痰嗎？醫學解析喉嚨卡卡的真相
重點摘要 (TL;DR)
醫學研究發現，喝牛奶並不會真的產生痰液，而是牛奶的質地讓喉嚨原有的黏液感覺變濃稠，產生卡卡的錯覺。只要喝一些開水清喉嚨，即可有效減輕此症狀。
長輩的叮嚀與感受
長輩常會叮嚀：「咳嗽的時候不要喝牛奶」
或者我們自己喝牛奶後，感覺喉嚨會產生痰，感覺黏黏卡卡的。
醫學原理：生痰的真相
但這是真的生痰了嗎？ 原理到底是什麼？
原來在醫學上也有討論到這一塊，研究發現並不是真的產生了痰液，而是牛奶的質地，讓喉嚨本身的「黏液感覺變濃稠了」，所以才讓人以為是產生了新的痰。
如何解決喉嚨卡卡感
那要怎麼辦、怎麼解決呢？
其實只要喝一些開水，清一下喉嚨，就可以減輕這種感覺了。
