Springtime sniffles are no match to anti-histamines, medications that can help treat allergic reactions, including those to pollen and ragweed. So if there are medications that are antihistamine, then there must be a thing that ​is​ a histamine, right?

Right. A histamine is a chemical found in our bodies that can mount an immune response if it feels the body is under attack, according to the U.S. National Library of Medicine. And there are actually foods that are high in histamine. In most people, the histamine in foods doesn't cause any problems, and you may not even realize you're consuming the chemical.

However, there are people who have histamine intolerance, in which their bodies don't break down the histamine they consume, which can lead to allergic symptoms or histamine effects.

So what are the symptoms of histamine intolerance? Some include nasal congestion, sinus problems, digestive issues, irregular menstruation, nausea, vomiting, headache and migraine. In fact, people with migraines may also have lower levels of the enzyme needed to break down histamine, according to a February 2018 study in the Journal of Physiology and Biology.

If you're trying to figure out what foods trigger a histamine response, it's worth keeping a food diary to target which may be problematic. A health care professional might recommend an elimination diet, in which you remove suspect foods for four to six weeks, and re-introduce them one at a time to determine if you experience symptoms.

While it's hard to quantify exactly how ​much​ histamine a food may have, generally speaking, foods that are processed, fermented or aged tend to have higher amounts.

Read on for a list of high-histamine foods, or picks that can trigger a histamine response, which can lead to those histamine effects.

Fermented vegetables, like sauerkraut and pickles, are good sources of gut-friendly probiotics, but they tend to have higher levels of histamine, although those levels can fluctuate depending on how they're prepared and how long they've aged.

2. Alcohol

Alcohol is a type of fermented drink that can cause histamine reactions.

Sure, a responsible glass of wine or two per week might have some health benefits, but if you struggle with histamine intolerance, alcohol — a fermented drink — might be a non-starter. In some beers, the grain used might also contribute to histamine symptoms.

3. Processed Meats

Processed and packaged meats like deli meat should be consumed in moderation due to health risks.

In general, it's sage advice to limit your intake of processed and packaged meats, which, in high amounts, have been linked to chronic diseases, including colorectal cancer, according to the World Cancer Research Fund.

Packaged meats, like deli meats, may also contain high amounts of histamine. And it turns out ​how​ your meat is cooked may affect histamine levels, too. Frying and grilling meat may increase histamine levels in food, while boiling had little to no effect. In some cases, it may even decrease levels, according to a December 2017 study inAnnals of Dermatology.

4. Aged Cheese

Cheese is a nutritional powerhouse, but aged varieties can have high levels of histamine.

Bad news for cheese and wine lovers: Histamines plague both. Aged cheeses contain high levels of histamine, although the levels tend to vary based on how long a cheese is aged. Some aged cheeses include Gorgonzola, Blue, Gouda, Parmigiano and cheddar.

Because cheese is a good source of nutrients, including protein, fat and calcium, opt for non-aged varieties.

5. Fermented Dairy

Fermented dairy like kefir, buttermilk and yogurt contain high levels of histamine.

Certain dairy products, like buttermilk and kefir, are fermented, making them high in histamine — much like fermented vegetables. Choose non-dairy alternatives like plant-based milks and yogurts.

6. Fish

Certain fish like tuna can contain high levels of histamine. Reactions may be misconstrued as allergic reactions to the fish.

Not all fish are high in histamine, but certain varieties, including tuna, mackerel, mahi mahi and anchovy, contain high amounts. It's possible to experience histamine toxicity if you have a histamine intolerance, according to the American Academy of Allergy, Asthma and Immunology (AAAAI). But this is not an allergic reaction to the fish itself.

The most common cause of this type of histamine toxicity is due to spoiled fish, which, per the AAAAI, causes an overgrowth of bacteria that converts histidine into high levels of histamine.

7. Chocolate

Antioxidant-rich chocolate also contains high levels of histamine.

Your favorite sweet treat might also contain high levels of histamine. While it's unclear exactly ​how​ much histamine chocolate and cocoa-based products have, a food diary can help determine if they're a trigger food for histamine intolerance.

8. Canned Foods

Canned foods are nutritious, but tend to be higher in histamines.

There's no doubt that canned fruits and vegetables are a nutritious option when fresh foods aren't available. But for some, canned foods might trigger a histamine response.
