Vin rouge
Histamine is present in a variety of fermented products such as wine, aged cheeses, and sauerkraut. Red wine has 20–200% more histamine than white wine, and those who react to it may be deficient in the enzyme diamine oxidase. Experts believe that in some individuals, alcohol consumption may lead to elevated plasma histamine levels even in the absence of histamines in the beverage consumed. A study of 16 people with an intolerance to red wine found no difference in reactions to low and high histamine wines. Other biogenic amines may also have an effect.
