How to Reduce Histamine in Your Body

We all have histamines in our bodies, and normally they only cause minor seasonal allergies. However, you could be especially sensitive to these chemicals, which can cause real problems in your daily life. Since most histamines come from food, the best treatment for histamine intolerance is dietary changes. Try these steps to remove histamines from your diet and start feeling better.

1
Fresh, non-preserved foods: Generally, any food with preservatives is high in histamines. This means that fresh, non-packaged food is your best bet. Try to eat as many fresh meals as you can to keep your histamine levels down.^{[1]XResearch source}
- Meat, poultry, and fish are all fine, as long as they aren't packaged or preserved.
- Frozen foods, like meat, fish, and vegetables, are usually okay as well, as long as they were frozen fresh and don’t have any added preservatives.
- It might help to cook some of your own meals, so this is a great time to learn some new recipes!
2
Fruits and vegetables: Most of these are safe, and they’re always healthy choices. Incorporate plenty of fresh fruits and vegetables in your meals to get essential vitamins and nutrients in your diet.^{[2]XResearch source}
- There are some exceptions to this rule. Generally, avocados, bananas and plantains, citrus fruits, eggplant, and spinach are all high in histamines, so steer clear of those.^{[3]XResearch source}

Whole grains: These are naturally lower in histamines, so they shouldn't cause any trouble. Feel free to include bread, pasta, rice, oats, and flour in your normal diet.^{[4]XResearch source}
- Sourdough bread and yeast products like marmite tend to be higher in histamines than whole-grain breads, so try to avoid these.^{[5]XResearch source}
- Whole grain and whole wheat products tend to be healthier than white varieties, so switch over to these types if you usually eat white bread and rice.
4
Milk substitutes and eggs: Dairy products like cheese and milk tend to raise your histamine levels, but milk substitutes are fine. Replace the milk in your diet with soy, oat, or coconut types instead. Fresh eggs are also fine.^{[6]XResearch source}
- Some people tolerate goat or sheep milk better than cow milk, so try this out if you want more dairy in your life. There are also cheeses made from these milk sources.^{[7]XResearch source}

1
Fermented, pickled, or preserved foods: Any type of preservatives tend to be high in histamines. Cut out things like cured or smoked meat, sausages, bacon, canned items, or anything packed in vinegar.
- Common fermented foods include yogurt, kefir, miso, and pickles. Sauerkraut, in particular, has shown high concentrations of histamine.
- Frozen meals are usually high in preservatives too, so skip these as much as you can.
2
Citrus fruits: While these are delicious, and normally healthy, citrus fruits trigger your body to release histamine. Avoid oranges, lemons, limes, grapefruits, and similar foods.
- This goes for citrus fruit juices too. Cut out the orange juice and lemonade.
- Remember to still have plenty of non-citrus fruits in your diet. This is important to get all the nutrients you need to stay healthy.
Vegetables are usually very healthy, but not if you have histamine intolerance. Most are fine, but tomatoes, eggplant, spinach, and avocados release histamines. Most legumes and beans are also high in histamines, so you’ll have to avoid them too.^{[8]XResearch source}
4
Milk and cheeses: These dairy products tend to release histamines. Either cut them out or use dairy substitutes to avoid triggering your symptoms.^{[9]XResearch source}
- Remember that you can still have milk substitutes from soy or coconut.
- Histamine levels in cheeses may vary depending on the age and temperature it was stored.
5
Tree nuts, cinnamon, and chocolate: Products from trees like this tend to be higher in histamines, and allergens in general. Be careful to avoid tree nut products, as well as products like cinnamon and chocolate.^{[10]XResearch source}
- This goes for items containing tree nuts too. Almond milk, for example, might bother you.
6
Wine and beer: Both of these drinks have a lot of preservatives, especially sulfites. They are more likely to raise your histamines than other types of alcohol.
- Technically all alcohol is bad for your histamine levels, so if you’re very sensitive, quitting drinking altogether is a good idea.

1
See an allergist if you have symptoms of histamine intolerance. Histamine intolerance is tough to spot, and you can’t diagnose it yourself at home. Testing and monitoring from an allergist is the only surefire way to know if you have the condition. If you do suspect that you have a histamine intolerance, make an appointment with an allergist to get tested.^{[11]XResearch source}
- The main symptoms of histamine intolerance look like seasonal allergies. You might experience sneezing, itchy eyes, congestion, headaches, and hives after eating histamine-rich foods.
- Some people also experience gastrointestinal issues like bloating, diarrhea, or constipation.
- There are no reliable lab tests for histamine intolerance, so your doctor will probably suggest switching to a strict, histamine-free diet to see if that makes you feel better.
2
Take antihistamines to control your symptoms. Antihistamine medications block histamines in your body and prevent them from causing trouble. If your symptoms don’t get better with dietary changes, ask your doctor for the best medication to control your symptoms.^{[12]XTrustworthy SourceMedlinePlusCollection of medical information sourced from the US National Library of MedicineGo to source}
- Common antihistamines include loratadine, diphenhydramine, and cetirizine.
- Don’t take antihistamines without asking your doctor first. These are usually not meant for long-term use.
- Your allergist might also prescribe a stronger antihistamine.
3
Work with a dietician if you have trouble sticking to your diet. A low-histamine diet is tough, so it’s completely normal if you need some help. See a dietician and tell them about your histamine intolerance. They can draw up a diet plan for you so you don’t have to stress about picking the right foods.^{[13]XResearch source}
- Allergists usually work closely with dieticians, so ask your allergist for a recommendation or a referral.

Since an anti-histamine diet is very restrictive, don't start one until you're diagnosed with histamine intolerance. If you start without a doctor's guidance, you could end up malnourished.
