Though it is thought to be an Asian affliction exclusively, it is a misnamed syndrome which is found in half of all Asians, small numbers of Caucasians, and ALL Native Americans.
Although most with this condition view it as a minor inconvenience, it has been suggested that those with alcohol flush reaction may be at higher risk for alcohol related conditions such as liver disease, asthma, and cancer of the esophagus. Among flushers who are heavy drinkers the incidence of upper gastrointestinal tract cancer is about 50 times higher than normal. Higher rates of head and neck cancer have also been noted.
A functional shot/mixer supplement (Google: "Cheerz IntelliShot Asian flush") has garnered strong anecdotal evidence of efficacy against this condition.
Asian flush results from the fact that the rate of metabolism of alcohol in one's asian digestive system is unfortunately much lower than the alcohol intake rate - even when one is drinking alcohol at a reasonable rate.
As a result, many asians have very low alcohol tolerance. However, asian/european half-breeds (sometimes referred to as eurasian, mixers and halfies) are sometimes lucky enough to have a genetic cure for this condition.
"Good thing I'm eurasian ... my Irish blood is neutralizing the asian flush."
