BOSTON - Many of us will be reaching for that "bottle of red" on Thanksgiving Day, but some will suffer soon after with a throbbing headache.
Scientists may now have a clue why.
The so-called "red wine headache" can occur within 30 minutes to three hours after drinking even a small amount.
Researchers at the University of California, Davis have discovered that a flavanol found naturally in red wines can interfere with the proper metabolism of alcohol which can lead to a headache, as well as nausea and flushing.
The compound is an antioxidant which can have health benefits but when combined with alcohol, it can cause a problem.
Scientists will now launch a small clinical trial to see whether wines with more or less of this flavanol trigger red wine headaches in humans.
