Final Thoughts
Histamine is a chemical responsible for a few major functions, including:•sending messages to your brain•triggering the release of stomach acid to help digestion•releasing after injury or allergic reaction as part of your immune responseSee full list on healthline.comBecause you have histamine receptors throughout your body, histamine intolerance can affect several body systems. In a small 2019 study, participants experienced an average of 11 symptoms, with 96.8% experiencing more than 3 symptoms.Histamine intolerance symptoms are nonspecific. That means they can appear like symptoms of other conditions. This can often make it challenging for doctors to diagnose.Gastrointestinal (GI) symptoms are the most common and include:•digestive issues•abdominal pain•bloatingSee full list on healthline.comYou naturally produce histamine along with the enzyme diamine oxidase (DAO). DAO is responsible for breaking down histamine that you take in from foods.If you develop a DAO deficiency and cannot break down histamine, you could develop histamine intolerance.Things that can affect your DAO enzyme or histamine levels include:•Genetics: You may have a gene mutation that causes your body to produce either less DAO or dysfunctional DAO.•Medications: Some medications can temporarily block DAO functions or prevent production, including:•phlegm reducers, such as acetylcysteineSee full list on healthline.comFoods to consider limitingA health-promoting diet contains moderate levels of histamine. However, some foods high in histamine can trigger inflammatory reactions and other negative health events.
The benefits of a histamine-limiting diet are still an uncertain field of study. More research is needed. Limiting these foods may help some but not others. Histamine-rich foods include: •alcohol and other fermented beverages •fermented foods and dairy products, such as yogurt and sauerkraut •dried fruits •avocados •eggplant •spinach •processed or smoked meats •preserved fish and shellfish •aged cheeseSeveral foods can also trigger histamine release in your body, such as: •alcohol •bananas •tomatoes •wheat germ •beans •papaya •chocolate •citrus fruits •nuts, specifically walnuts, cashews, and peanuts •food dyes and other additives •fish •porkDrinks that block DAO production include: •alcohol •black tea •mate tea •energy drinksIn a systematic review from 2021, many of the foods typically listed as high-histamine or histamine-triggering may not actually have this effect depending on the person. For instance, based on this systematic review, citrus fruits and fish were very low in histamine. Research results also showed that various studies focusing on a low-histamine diet really differed in their approach, and the list of foods to avoid or to consume was significantly different. The best strategy may be to try eliminating foods you suspect that are adversely contributing to your health events to see if doing so helps or changes your symptoms.Foods to eatIf you have histamine intolerance, incorporating low-histamine foods into your eating pattern can help reduce symptoms. There are several variations of low-histamine eating plans. It’s important that you consult a healthcare professional such as a dietician before you eliminate foods from your eating plan. Some foods low in histamine include: •fresh meat and freshly caught fish •non-citrus fruits •eggs •gluten-free grains, such as quinoa and rice •dairy substitutes, such as coconut milk and almond milk •fresh vegetables except for tomatoes, avocados, spinach, and eggplant •cooking oils, such as olive oilSee full list on healthline.comOther than making changes to your eating pattern, there’s not much you can do to fix histamine intolerance.Antihistamines may help reduce symptoms in the short term.See full list on healthline.comBefore reaching a diagnosis, a doctor will eliminate other possible disorders or allergies that cause similar symptoms.They may also suggest following an elimination diet for 14–30 days. This diet requires you to remove foods high in histamine or histamine triggers before slowly reintroducing them to watch for new reactions.A doctor might also request a blood sample to analyze whether you have a DAO deficiency.Another way to diagnose histamine intolerance is through a prick test. A typical prick test checks for allergic reactions within 20 minutes. But a prick test for histamine intolerance will typically require a 50-minute wait to get results.See full list on healthline.comHow do you fix histamine intolerance?Making changes to your eating pattern is the main way you may be able to fix histamine intolerance. Taking antihistamines may help reduce short-term symptoms. Some research suggests that taking DAO supplements may help, but more research is needed.What triggers histamine intolerance?Your body produces histamine. It also produces an enzyme, DAO, that breaks down histamine. If your body has a problem producing DAO, you may develop histamine intolerance. There are many things that may affect DAO production, such as eating too many foods that contain histamines or foods that block DAO, having a genetic mutation, taking certain medications (like acetylcysteine, metoclopramide, propafenone, dihyrdalazine, or amitriptyline), or having IBS.See full list on healthline.comHistamine intolerance can cause uncomfortable symptoms, but a low-histamine eating plan may help ease symptoms.Diagnosing histamine intolerance can be challenging as symptoms are similar to other allergens, disorders, or infections. During the diagnosis process, a doctor will need to eliminate similar medical conditions.
