DAO activity is influenced by enzyme kinetics, including substrate concentration, competitive inhibition, and environmental factors such as pH and temperature. Alcohol, certain drugs, and high levels of other biogenic amines can reduce DAO’s ability to metabolize histamine, which may lead to systemic accumulation. This mechanism explains why individuals with low DAO activity may experience histamine-related symptoms even after consuming small amounts of high-histamine foods. Researchers studying DAO must account for these variables when designing activity assays or interpreting results to ensure accuracy and reproducibility.
Histamine Content in Alcoholic Beverages
Reduced DAO activity means histamine from food or beverages is more likely to accumulate in the body, prolonging its effects. Alcohol’s impact on histamine breakdown is a nuanced process, influenced by both the type of alcohol and individual metabolic factors. Histamine, a compound involved in immune responses and digestion, is naturally present in certain foods and beverages, including wine and beer. When consumed, alcohol can interfere with the enzymes responsible for breaking down histamine, particularly diamine oxidase (DAO). This interference can lead to elevated histamine levels in the body, potentially triggering symptoms like headaches, flushing, or nasal congestion in sensitive individuals.
Alcohols to Avoid
Gin, with its botanical infusions, remains low in histamines as long as the botanicals themselves are not high-histamine ingredients like citrus peels. Rum, derived from sugarcane, undergoes a similar distillation process, minimizing histamine levels. This makes these spirits a more predictable choice for those monitoring histamine intake. Most reactions to red wine are actually due to histamines or sulfites rather than an allergy to the alcohol itself. Red wine is naturally high in histamines (the result of the fermentation process), which can cause sneezing, headaches, and nasal congestion.

For a mild intolerance to alcohol, you don’t need to see a healthcare professional. Simply avoid alcohol, limit how much you drink, or avoid certain types of alcoholic beverages. More commonly, symptoms related to alcoholic beverages might be an allergic reaction to something in the alcoholic beverage, such as sulfites, grains or preservatives. If your body’s store of diamine oxidase, a histamine-clearing enzyme, have been depleted for any reason, you can experience very unpleasant symptoms upon drinking alcohol. Beyond that, alcohol appears to both provoke the release of histamine and inhibit the function of diamine oxidase (DAO), one of the two enzymes which clear histamine from the gut. This three-fold assault causes the buildup of histamine, resulting in allergy symptoms and various other inflammatory reactions.
- Ethanol is a solvent that immediately strips away the protective moisture and fatty layers of the pharyngeal mucosa upon contact.
- Although their symptoms may overlap, they differ significantly in mechanism, pathology and clinical severity.
- They can help you sort out whether it’s an allergy, intolerance or something else.
- Some people may have a histamine intolerance that may contribute to GI or other symptoms.
- Furthermore, alcohol is a vasodilator, meaning it opens up your blood vessels.
- The goal is to identify your “high-impact” triggers, not to prove you react to everything.
- Plain gin, without added sugars or artificial flavors, is generally a better choice than flavored gins.
Distilled spirits are generally lower in histamines because the distillation process removes many impurities, making them a better option for those with histamine sensitivity. Very rarely, people who develop reactions later in life may have a more serious condition, such as Hodgkin lymphoma. Fermentation has been used for millennia to break down foods to make them easier to digest or more bio-symbiotic with our guts.
- Lifestyle adjustments—such as avoiding known triggers (temperature extremes, alcohol, insect stings, stress, and certain medications)—can significantly reduce the frequency and intensity of reactions.
- The distillation process tends to remove many of the compounds that contribute to histamine production.
- Common symptoms of histamine toxicity include migraines, nasal congestion, fatigue, hives, and digestive issues.
- Alcohol’s inhibition of DAO occurs primarily in the gut, where the enzyme is most active.
- Low-histamine diets have been recommended for individuals with DAO deficiency to reduce symptoms, although effectiveness varies, and more long-term studies are needed.
Histamine Intolerance: Beyond Allergies
Knowing how to manage these symptoms can help make drinking alcohol a more enjoyable and safer experience. White wines generally tend to have lower histamine levels than red wines, and some wineries utilize techniques to minimize histamine production. Exploring different types of wine and paying attention to the specific fermentation and aging methods used can help identify potentially lower-histamine options. Testing for histamine levels in alcoholic beverages is not consistently performed or disclosed by manufacturers. Additionally, staying well-hydrated by drinking plenty of water can help dilute histamine and support its excretion.
