Mystery of what causes red wine headaches solved

DAVIS, Calif. — Scientists have uncovered the explanation why ingesting crimson wine might provide you with a headache. Analysis exhibits {that a} pure compound, generally known as a flavanol, present in crimson wines can disrupt the physique’s alcohol metabolism, resulting in complications.

The College of California-Davis crew recognized this flavonol as quercetin, which is of course occurring in a wide range of vegetables and fruit, together with grapes. Quercetin is acknowledged as a useful antioxidant and is even out there as a dietary supplement. Nonetheless, when it interacts with alcohol, it could trigger antagonistic results.

“When it will get in your bloodstream, your physique converts it to a distinct kind known as quercetin glucuronide,” says wine chemist and corresponding creator Andrew Waterhouse, professor emeritus with the UC Davis Division of Viticulture and Enology. “In that kind, it blocks the metabolism of alcohol.”

Additionally they discovered that totally different wines had totally different quantities of the pain-inducing flavanol relying on how a lot daylight the grapes had.

“Quercetin is produced by the grapes in response to daylight,” Waterhouse continues in a university release. “In the event you develop grapes with the clusters uncovered, equivalent to they do within the Napa Valley for his or her cabernets, you get a lot greater ranges of quercetin. In some instances, it may be 4 to 5 instances greater.”

Because of consuming this flavanol-filled wine individuals can accumulate a toxin known as acetaldehyde which causes painful signs.

“Acetaldehyde is a well known toxin, irritant and inflammatory substance,” explains lead creator Apramita Devi, a postdoctoral researcher with the UC Davis Division of Viticulture and Enology.

“Researchers know that top ranges of acetaldehyde may cause facial flushing, headache and nausea.”

Usually, a crimson wine headache can happen inside half-hour to 3 hours after ingesting as little as a small glass of wine.

“We postulate that when prone individuals devour wine with even modest quantities of quercetin, they develop complications, notably if they’ve a preexisting migraine or one other major headache situation,” provides co-author Morris Levin, professor of neurology and director of the Headache Heart on the College of California-San Francisco.

“We predict we’re lastly heading in the right direction towards explaining this millennia-old thriller.  The following step is to check it scientifically on individuals who develop these complications, so keep tuned.”

The crew plans to conduct human medical trials to get additional solutions as there are nonetheless many unknowns concerning the causes of crimson wine complications. It’s unclear why some individuals appear extra prone to them than others.

Researchers don’t know if the enzymes of people that endure from red wine headaches are extra simply inhibited by quercetin or if they’re simply extra simply affected by the buildup of the toxin acetaldehyde.

The examine is revealed within the journal Scientific Reports.
