Hypersensitivity and reactions to foreign substances (allergens). Consuming foods high in tyramine and histamine can be the cause of a headache (Migraines). Caution is advised with real sulfite allergy sufferers. With them, the “sulfite asthma” can be triggered by minimal amounts of sulfur. These people should avoid wine and other sulphurous alcoholic beverages. Symptoms can be asthma-like and show up in itching, hives, runny nose, and drop in blood pressure. In the small patient group of "sulfite allergy sufferers", around 10% of asthmatics are assumed.
Allergenic substances can also be present in wine. Most of all, these are protein compounds (when using related substances at beautiful ) histamine. sorbitol and tyramine (especially with red wines with malolactic fermentation ), against sulfur (is included in almost every wine) and also the alcohol (Ethanol) itself. In this regard, however, there are different limit values in the mg / l range for each substance. A list of all substances with maximum limit values is below ADI (Acceptable Daily Intake) included.

However, there was no change for the wine as a corresponding regulation had been in force since the 2012 vintage.
If the limit value of 0.25 mg / l protein-containing fining agent is used or exceeded, this must be on the label in the form of egg, egg protein, egg product, lysozyme from egg or albumin from egg, milk, milk product, casein made from milk or milk protein with "contains ..." in front. For the determination of the salary is exclusively the ELISA method authorized. Since 2005, this has also been prescribed for sulfur (sulfites, sulfur dioxide) with a limit of 10 mg / l by means of the EU regulation (see under sulphurous acid ).
Wines are already being produced today for diabetic and vegetarian or vegans meet certain requirements, but they must not be called diabetic wine etc. NASA scientist Richard Mathies found a method in 2007 to quickly identify components of the wine that cause headaches. The substances histamine and tyramine, which can be present in red wines to a possible problematic extent, can thus be detected by means of a sensor. What amounts of alcohol are probably not harmful to health when consumed regularly is shown under health described. See also under alcoholism and intoxication,
