- ALDH2 deficiency affects roughly one-third of people of East Asian descent, producing facial flushing when drinking because reduced enzyme activity lets toxic acetaldehyde accumulate in the body.
- People who are heterozygous for the ALDH2*2 mutation typically keep drinking past mild symptoms and face elevated risk of cardiovascular disease, brain disorders, pancreatitis, and esophageal cancer, the op-ed states.
- Brian Zhang, a second-year M.D. student at Stanford, urges clinicians to screen flushing patients with questionnaires and ethanol patch testing, citing a 2010 randomized study in which genetic feedback reduced 30-day drinking among Asian American young adults.
- Nectar, a canned seltzer brand, drew criticism in the piece for an AAPI Heritage Month "Asian Glow Up" campaign that reframed the flush as a beauty moment without a health disclaimer.
- Antihistamines like Pepcid AC can hide visible redness but do not lower acetaldehyde levels in the blood, letting users drink past their body's warning signals, Zhang warns.
- Zhang's own father significantly cut his drinking after learning about ALDH2 deficiency through an ethanol patch test performed at a free clinic while they were on FaceTime.
Why it matters: Roughly one-third of people of East Asian descent carry an inherited enzyme deficiency that turns routine social drinking into a documented cancer and cardiovascular risk, yet the "Asian glow" reaction is widely treated as a cosmetic quirk. Heterozygotes who keep drinking past mild flushing face elevated rates of esophageal cancer, pancreatitis, and brain disorders, making proactive clinician screening a concrete — and currently underused — prevention opportunity for a population of hundreds of millions worldwide.
