#quercetin

Quercetin, a flavonoid in red wine, could be the cause of headaches in some individuals.

When quercetin is ingested with alcohol, it can prevent the body from metabolizing and detoxifying the wine's alcohol, leading to a buildup of acetaldehyde.

The study aims to help individuals identify the cause of red wine headaches and to understand migraines and headache mechanisms more generally. [ more ]

Red wine headaches may be caused by the buildup of a toxin called acetaldehyde, triggered by the presence of quercetin in the wine.

Migraine sufferers and those prone to headaches are more likely to experience red wine headaches.

Grape varietals grown in high sun exposure have higher levels of quercetin, but fermentation and aging also play a role. [ more ]

The cause of red wine headaches, also known as RWH, has been narrowed down to a flavonol called quercetin.

Red wines typically have more amines, sulfites, flavonoids, and tannins, particularly a compound called resveratrol.

The cause of RWH is still not fully understood, and more research is needed to understand the mechanisms behind the phenomenon. [ more ]

A compound in red grapes called quercetin may be the reason why some people get headaches from red wine.

Higher quality red wines with more exposure to sunlight are more likely to cause headaches.

Sulphites and histamine have been previously suggested as possible causes for red wine headaches. [ more ]
