Contrary to popular belief, it's not the sulfites that cause your RWH syndrome (red wine headache). Research suggests that the culprits could be histamine and tyramine, chemical substances that are naturally present in wine. (Histamine dilates blood vessels; tyramine first constricts, then dilates blood vessels). According to several studies, red wines contain more histamine than whites and sparklers. So, people who have trouble with histamine in red wine might also gets headaches from aged cheeses, smoked or cured meats and dried fruits.
