Lots of questions….
This article will cover everything you need to know about mushrooms and histamine intolerance. We’ll explain what histamine intolerance is, look at which mushrooms tend to be higher and those that are a low-histamine food, and provide tips for incorporating low histamine fungus into your diet.
What is Histamine Intolerance?
Histamine intolerance, also known as mast cell activation syndrome (MCAS), is a condition that causes a person to react to normal levels of histamine in foods. Histamine is a chemical involved in the body’s immune response, gut function, and regulation of physiological processes. Some people have an allergy to mushrooms where their immune cells release histamine in response to contact with mushrooms.
When you have histamine intolerance, your body lacks sufficient levels of the enzyme diamine oxidase (DAO) needed to break down histamine. This causes histamine to accumulate and trigger unpleasant symptoms like:
- Hives, flushing, itching
- Headache, migraine
- Fatigue
- Digestive issues
- Changes in blood pressure
- Respiratory symptoms like cough or congestion
Symptoms often start shortly after consuming foods high in histamine. Following a low histamine diet and avoiding histamine liberators can provide relief.
Are All Mushrooms High in Histamine?
Many people with histamine intolerance are told to completely avoid mushrooms. However, not all mushrooms contain high amounts of histamine.
Certain mushrooms like shiitake are higher in histamine and best limited or avoided. But other varieties including white button, cremini, and portobello tend to be lower in histamine levels.
Freshness is also a factor. The histamine content in mushrooms increases as they age after harvesting. So freshly cooked mushrooms typically contain less histamine vs. those that have been stored for prolonged periods.
While mushrooms are not recommended in large amounts on a low histamine diet, enjoying moderate portions of low histamine varieties a few times per week is unlikely to cause issues for most.
Tips for Choosing Low Histamine Mushrooms
Here are some tips to choose and prepare low histamine mushrooms:
- Select fresh mushrooms – Look for mushrooms with firm, plump caps and avoid any that appear slimy or decayed. The fresher the better.
- Cook from raw – Don’t use pre-cooked, canned, or frozen mushrooms as the histamine content rises with processing. Always cook fresh mushrooms yourself.
- Limit portion size – Even low histamine mushrooms are best enjoyed in moderation. 1⁄2 to 1 cup a few times per week is a good guideline.
- Opt for white, cremini, or portobello – These 3 varieties tend to be lower in histamine compared to shiitake and other types.
- Avoid old mushrooms – Check expiration dates and don’t purchase mushrooms that are close to expiry. Histamine increases as mushrooms age.
- Cook thoroughly – Ensure mushrooms are cooked through, as some compounds may act as histamine liberators when raw.
Following these tips helps reduce the histamine content of mushrooms, making them an option for fitting into an otherwise low histamine diet.
Best Low Histamine Mushrooms
Wondering which specific mushrooms are lowest in histamine? Here are some excellent low histamine options:
White Button Mushrooms
White mushrooms, along with closely related cremini mushrooms, are one of the best choices for low histamine. Simple white button mushrooms have minimal detectable histamine and do not appear to trigger histamine intolerance symptoms in most people when enjoyed in moderation.
Portobello Mushrooms
Portobello mushrooms are mature cremini mushrooms with large, meaty caps. They are essentially the same mushroom, just fully grown. So like cremini and white button mushrooms, portobello ranked low on laboratory analysis of histamine levels. Their larger size makes them ideal for stuffing, grilling, and using in place of burgers.
Enoki Mushrooms
Enoki mushrooms are a white variety with tiny caps and long, thin stems. They have a mild, slightly sweet flavor. Research has found fresh enoki mushrooms have low histamine levels and do not seem to provoke histamine intolerance, making them another suitable pick.
Oyster Mushrooms
Oyster mushrooms have a delicate texture and taste akin to their namesake. Studies show raw oyster mushrooms are low in histamine, though histamine content may rise slightly with cooking. Enjoying moderate portions of FRESH oyster mushrooms a few times per week is likely fine.
Reishi Mushrooms
Reishi is an edible medicinal mushroom used for its anti-inflammatory and immune boosting benefits. Fresh reishi is generally low histamine, though levels may increase if allowed to age. Look for young reishi mushrooms and enjoy sparingly.
Higher Histamine Mushrooms to Limit or Avoid
On the other hand, these mushrooms tend to be higher in histamine and are best minimized or avoided with histamine intolerance:
Shiitake Mushrooms
Of all the mushrooms, shiitake ranks among the highest in histamine content. In addition to containing histamine, shiitake mushrooms have histamine liberators that can trigger mast cells to release additional histamine. For those with marked histamine intolerance, shiitake is best avoided entirely.
Maitake Mushrooms
Also called hen of the woods, maitake is another mushroom that routinely tests higher in histamine. While not as extreme as shiitake, maitake mushrooms are less ideal for a low histamine diet and best limited to small amounts or avoided.
Aged and Canned Mushrooms
Remember, the histamine content in mushrooms increases as they age after harvesting. So mushrooms that have been stored for prolonged periods before sale tend to be higher in histamine. This includes canned mushrooms and those approaching expiry dates. Always check freshness and opt for recently harvested mushrooms.
Other Tips for Managing Histamine Intolerance
Aside from choosing low histamine mushrooms, here are some other tips for minimizing symptoms:
- Avoid other high histamine foods like aged cheese, sour cream, yogurt, kombucha, sauerkraut, smoked meat, dried fruit, alcohol, and processed meats
- Eat more fresh, low histamine fruits and vegetables like lettuce, carrots, squash, and berries
- Take DAO enzyme supplements before eating foods higher in histamine
- Choose freshly cooked meals instead of leftovers or frozen foods
- Keep a food journal to identify problematic items that provoke symptoms
- Work with a healthcare professional or dietitian knowledgeable in low histamine diets

Q: Are mushrooms high in histamine levels?
A: No, mushrooms are generally low-histamine foods. Fresh mushrooms contain minimal histamine, making them suitable for people with histamine tolerance issues. However, as mushrooms age or become preserved (dried, canned, or fermented), their histamine content can increase. To minimize histamine intake, it’s best to consume fresh mushrooms shortly after purchase and avoid preserved varieties if you’re sensitive to histamine.
Q: Can including mushrooms in a low-histamine diet cause symptoms in people with histamine intolerance?
A: Most people with histamine intolerance can safely include fresh mushrooms in a low-histamine diet without experiencing symptoms. However, individual responses vary. Some highly sensitive individuals might experience allergy symptoms or a reaction even to foods with small amounts of histamine. If you notice symptoms after consuming mushrooms, consider removing them from your diet temporarily, then reintroducing them carefully to determine your personal tolerance level.
Q: What are the best types of edible mushrooms for a low-histamine diet plan?
A: The best mushrooms for a low-histamine diet plan are fresh white button mushrooms, cremini, and portobello mushrooms, as these varieties typically contain minimal histamine when fresh. Shiitake and oyster mushrooms are also generally well-tolerated. Remember that freshness is key—always choose recently harvested mushrooms and consume them promptly to prevent histamine production that naturally occurs as foods age.
Q: How does cooking affect histamine levels in mushrooms?
A: Cooking doesn’t reduce histamine levels in mushrooms that already contain histamine. However, cooking fresh mushrooms promptly after purchase doesn’t significantly increase histamine content. The key factor is time—the longer mushrooms sit (whether raw or cooked), the more histamine they can develop. For those with histamine intolerance, it’s best to cook fresh mushrooms soon after purchase and consume them immediately rather than storing leftovers.
Q: What are signs that mushrooms might be triggering a histamine reaction?
A: Signs that mushrooms might be increasing histamine levels in your body include headaches, skin flushing or hives, digestive issues (stomach pain, diarrhea, nausea), nasal congestion, or fatigue after consumption. These symptoms can be similar to food intolerance or allergic reaction symptoms. If you notice these issues consistently after eating mushrooms, they might not be suitable for your personal low-histamine diet, despite being generally classified as low-histamine foods.
Q: How can I incorporate mushrooms in a low-histamine diet safely?
A: To safely include mushrooms in a low-histamine diet, choose fresh mushrooms rather than dried or preserved varieties. Use them within 1-2 days of purchase. Clean them just before cooking, not in advance. Cook them simply without fermented ingredients like soy sauce or vinegar that can increase histamine. Start with small portions to test your tolerance, and avoid leftovers, as histamine can increase in stored foods even after cooking.
Q: Are there alternatives if I can’t tolerate mushrooms on a low-histamine diet?
A: If mushrooms trigger symptoms in people with histamine intolerance, there are several alternatives that provide similar texture and umami flavor while being low in histamine. These include fresh zucchini, eggplant, cauliflower, or tofu (if soy is tolerated). Root vegetables like turnips, rutabaga, or kohlrabi can also work well in recipes that call for mushrooms. These substitutes can help maintain dietary variety while avoiding high histamine foods.
Q: Can supplementing with the enzyme that breaks down histamine help when eating mushrooms?
A: Yes, taking diamine oxidase (DAO) supplements—the enzyme that breaks down histamine—before consuming mushrooms may help some patients with histamine intolerance tolerate them better. These supplements can assist your body in processing any histamine present in the food. However, responses vary by individual, and supplements shouldn’t replace a proper low-histamine diet plan. Consult with a healthcare provider before starting any enzyme supplements to ensure they’re appropriate for your specific situation.
