  • You think youre a lightweight?


  • I almost got drunk of a slice of rum cheesecake.


  • Wait, is that even possible?


  • Hey guys, Chastity here filling in for DNews.

    大家好,我是 DNews 的主播 Chastity。

  • I don’t know about you, but when it comes to drinking, I’m the queen of lightweights.


  • I’ve been known to get drunk off of one mixed drink.


  • And when I drink even a small amount of alcohol, my face turns red instantly.


  • See, my friends have been making fun of me for it for years, but I’m putting it to an end now, with SCIENCE!


  • The condition is called Alcohol Flush Reaction, or AFR.

    這種症狀被稱為「酒精性臉紅反應」,英文簡稱為 AFR。

  • It’s pretty easy to tell when youve got it, since your face turns crazy red after drinking.


  • Other than facial flushing, symptoms of AFR include flushing of the neck and other parts of the body, heightened heart rate, headaches, and nausea.

    除了臉部泛紅,AFR 的症狀還包括脖子或其他身體部位的潮紅、加速的心跳、頭痛和噁心。

  • Now this is even after as little as one drink.


  • AFR is also known as theAsian gloworAsian Flush”, although Asians are not the only ones who suffer from it.

    AFR 也被稱為「亞洲紅臉症」,雖然亞洲人並非唯一的受害族群。

  • Over 500 million people worldwide experience flush reactions, with between 36 to 50 percent of them being of East Asian descent.

    全世界超過五億的人經歷過臉紅反應,而其中的 36-50% 是東亞族群。

  • Alcohol is typically metabolized in the liver, where it's first oxidized to acetaldehyde and then to acetate.


  • People with AFR carry a genetic mutation that disables this process.

    AFR 患者因為基因上的突變,所以無法運作此過程。

  • They have an inherited deficiency in the enzyme aldehyde dehydrogenase 2, or ALDH2.

    他們的乙醛去氫脢 (ALDH2) 有遺傳性的缺陷。

  • According to a PLOS Medicine study, approximately 8% of the world population is ALDH2 deficient.

    根據 PLOS 醫學研究顯示,全球約有 8% 人口缺乏 ALDH2。

  • ALDH2 is the enzyme that converts acetaldehyde.

    ALDH2 是轉化乙醛的酶。

  • Without it, were left with an accumulation of acetaldehyde up to 10 times the normal concentration!


  • According to Robert Swift, a physician and researcher at Brown University, acetaldehyde is like formaldehyde, which is embalming fluid.

    Robert Swift——布朗大學的內科醫生兼研究員指出,乙醛跟甲醛一樣,是一種不易腐壞的液體。

  • It destroys proteins, and it destroys DNA.

    乙醛會破壞蛋白質和 DNA。

  • Pretty nasty stuff, so imagine not being able to break that down!


  • Flushed faces, racing hearts, instant drunkenness.


  • Unfortunately, there is no cure for AFR since it’s a genetic issue.

    不幸的是,因為 AFR 是基因上的問題,所以無法醫治。

  • The only way to prevent flush reaction is to avoid alcohol completely.


  • But come on, that’s not going to happen.


  • So if you still want to drink but suffer from AFR, here are some tips to cope with it, courtesy of HealthXchange.

    所以若你受 AFR 之苦,但還是想喝酒時,以下有幾個由 HealthXchange 提供的應變措施。

  • 1. Drink moderately.

    1. 適量飲酒。

  • That’s two drinks for men and one drink for women per day.


  • Pick drinks with less alcohol content.


  • Eat before and/or while you're drinking.


  • Fatty foods and carbs can slow down the rate of alcohol absorption.


  • Drink plenty of water and/or non-alcoholic drinks.


  • Flush it out and quench your thirst.


  • And as a pro tip - if youve got the flush, don’t wear red while drinking.


  • Youll end up looking like a giant tomato.


  • Got any other tips or interesting drinking stories?


  • Share them in the comments below, and I’ll catch you next time.
