What is asian flush (alcohol flush) and how to prevent it?

Asian Flush (also known as alcohol flush reaction) refers to when a person becomes red in the face, neck, and upper body after consuming alcohol.

Why does Asian Flush Happen? 

Asian Flush is caused due to an accumulation of acetaldehyde, a toxin that is produced when the body metabolizes alcohol. Typically when someone consumes alcohol the body produces an enzyme that breaks down these toxins into a harmless substance that is easily processed by the body. 

However, some people are deficient in this important enzyme and much less able to break down these toxins. When these people drink alcohol, the toxins accumulate and end up causing the reaction known as Asian flush.

The cause of this condition is genetic and, as the name suggests, most prevalent among those of Asian descent.

According to a literature review by scientists at the University of California, this condition is experienced by:

34% of Korean Americans

50% of Chinese Americans

29% of Koreans

37% of Korean Chinese

46% of Japanese

34% of Han Chinese and Taiwanese

So what is the best way to reduce asian flush?

The best way to reduce asian flush is to reduce the build up of acetaldehyde. This is because those suffering from asian flush have a difficult time breaking down this toxin.

The most effective way to metabolize acetaldehyde is to boost an antioxidant in your body called glutathione. Treatment with NAC, Milk Thistle, Alpha Lipoic Acid and Vitamin C are great ways to boost glutathione levels. 

Boosting glutathione levels is a key part of The Hangover Secret. Simple hydration isn’t enough and neither is single targets towards glutathione.
