University of California scientists reckon they’ve solved the age-old enigma that’s had us rubbing our temples: why does red wine give you a headache?
Their findings point the finger at quercetin, a compound found in higher concentrations in red than white wine. Quercetin is believed to prompt an increase in acetaldehyde, a chemical culprit for noggin’ throbbing.
Dr Morris Levin, who directs the university’s Headache Center, warns that even “modest amounts” of quercetin can lead to cranial discomfort, especially for those already suffering from conditions like migraines.

Dr Levin explained: “We postulate that when susceptible people consume wine with even modest amounts of quercetin, they develop headaches, particularly if they have a pre-existing migraine or another primary headache condition.”
Furthermore, Dr Levin hinted that an enzyme deficiency common in about 40 percent of people from regions such as Korea, China, and Japan can make it tougher to break down acetaldehyde, reports the Mirror.
Yet, not everyone’s convinced by this theory. Professor Roger Corder, an emeritus professor at Queen Mary University of London, has raised the possibility that additional elements in the wine might be behind the discomfort.
These suspects include pectinases, which are thought to produce methanol, and dimethyl dicarbonate, a preservative often found in wines that are gentler on your wallet.
The theory that quercetin can slow down ageing is merely a “speculative hypothesis”, hanging on by the “only by the minutest of evidence”, according to one doctor. As Healthline explains, quercetin is a natural component in foods such as vegetables, fruits, and grains, and it’s believed to have numerous health benefits.
This antioxidant is known for its ability to fight free radical damage, which is often associated with chronic diseases like cancer and heart conditions. Additionally, it’s thought to reduce inflammation, allergy symptoms, and even high blood pressure.
Some people take quercetin supplements to boost their immunity, reduce inflammation and allergic reactions, enhance their workout results, and improve overall wellness. However, taking more than 1,000 mg daily could potentially cause headaches, stomach problems, and a tingling sensation.
If you’re dealing with a headache, the NHS recommends avoiding alcohol, not skipping meals, maintaining regular sleep patterns, and preventing eye strain from prolonged screen use. Persistent headaches that don’t respond to pain relief, are accompanied by throbbing pain on the side or front of the head, feelings of nausea, or headaches that regularly occur around your period are signs that you should see a doctor, according to NHS advice.
The NHS also advises seeking an urgent appointment or calling 111 if you or your child has a severe headache along with jaw pain while eating, blurred or double vision, a painful scalp, or numbness or weakness in your arms or legs.
