While some people tolerate drinking a glass of white wine or other alcoholic beverages well, they refrain from drinking red wine or risk contracting painful headaches. A situation for which there was no explanation until now. Researchers have pushed the envelope a little further and have perhaps found the “culprit”, a culprit despite himself since it is well known to be beneficial for health.

We would now know why you can get a headache when you drink red wine. American researchers have just hypothesized that quercetin is the culprit. This moleculemolecule antioxidant was generally presented as beneficial for health, especially since it is not consumed only by drinking a small glass of Bordeaux or Beaujolais. We’ll explain it to you.
Each time, it’s the same scenario when you choose this red vintage whose fruity notes you like: there is this bar at the forehead which spoils the pleasure. We are not talking about the headache linked to a hangover, but rather the pain caused after ingesting red wine. White wine is often blamed for the same reason, but it is indeed its purple counterpart which was the subject of a study at the University of California, located in Davis, and whose conclusions have just been published in the journal scientist Nature.
American researchers have thus detected a potential culprit in this type of unpleasant situation. Do you know quercetin? It is a flavonoid compound that is found in quantity in red wine, much more than in white wine. “ We propose that quercetin-3-glucoronide, derived from the different forms of quercetin present in red wines, inhibits ALDH2 (theenzymeenzyme which metabolizes acetaldehyde), leading to high acetaldehyde levels and subsequent onset of headaches in susceptible individuals », They explain. And to specify “ testing on human subjects is needed to test this hypothesis “.
Quercetin is found in many foods
This new avenue must be explored all the more as quercetin is generally presented as beneficial for health. This is the reason why it is found in the list of components of various food supplements. Furthermore, there is not only quercetin in red wine, but also in a whole bunch of other foods: apples, onionsonionscitrus fruits, capers, berries, spinachspinachand even in tea.
One of the notable characteristics of quercetin is its strong antioxidant power. This acts in this way to neutralize the free radicalsfree radicals in the body, unstable molecules associated with premature aging and various chronic diseases, such as heart disease and cancercancer.
Quercetin, interesting properties for various diseases
Researchers suggest that quercetin may help protect the body’s cells from damage caused by these free radicals, providing potential for preventionprevention diseases linked to oxidative stressoxidative stress. Another interesting property of quercetin lies in its effects anti-inflammatoriesanti-inflammatories potential.
Some scientists are also exploring quercetin’s potential as immune support. In addition, it could play a role in the management of allergies. Some individuals report a reduction in symptomssymptoms allergic when they eat foods rich in quercetin or take quercetin supplements.
