Red wine headaches ’caused by little-known ingredient’ as doctor shares how to avoid them
The age-old question of why red wine often leads to headaches may have finally been answered by scientists. Researchers from the University of California have pinpointed a compound called quercetin as a potential culprit behind this common side effect. Quercetin is found in higher amounts in red wine compared to white wine and can cause a build-up of acetaldehyde, a toxin associated with headaches and nausea.
Dr Morris Levin, who leads the University of California’s Headache Center, suggests that even small amounts of quercetin can trigger headaches in susceptible individuals. He explains that when people with pre-existing migraine or other primary headache conditions consume wine with quercetin, they are more likely to experience headaches. Notably, individuals of East Asian descent, including those from Korea, China, and Japan, may be more susceptible to these headaches due to difficulties in eliminating acetaldehyde caused by a specific enzyme.
However, not everyone agrees with this theory. Roger Corder, Emeritus Professor of Experimental Therapeutics at Queen Mary University of London, points to other wine ingredients such as pectinases and dimethyl dicarbonate as potential headache triggers. These substances can produce methanol, which may also contribute to headaches. Corder labels the quercetin theory as a speculative hypothesis with limited evidence supporting it.
Quercetin is a natural pigment found in various foods and is known for its potential health benefits, including antioxidant properties that help combat free radical damage and reduce inflammation. While some people take quercetin supplements for various health reasons, it’s important to note that excessive intake, more than 1,000 mg daily, can cause side effects like headaches and stomach pains.
If you experience headaches, the NHS recommends avoiding alcohol, maintaining regular meals, adequate sleep, and minimizing eye strain. Seeking medical advice is advised if headaches persist, painkillers are ineffective, or additional symptoms like nausea or throbbing pain occur.

In conclusion, while the link between quercetin in red wine and headaches presents a plausible explanation, further research is needed to fully understand this complex phenomenon and its implications for wine lovers.
