Are Mushrooms Good for IBS? : A Gut-Friendly Guide

Mushrooms and IBS don't always mix well. While some varieties like oyster mushrooms and canned champignons are low in FODMAPs and generally well-tolerated, others like shiitake and portobello can trigger digestive discomfort due to their higher FODMAP content. This is why many turn to mushroom supplements over fresh varieties.

If you’re dealing with Irritable Bowel Syndrome (IBS), you know how crucial it is to manage your diet carefully. One question that often comes up is whether mushrooms are a good choice. The answer isn’t straightforward because it depends on the type of mushroom and how your body reacts to certain compounds called FODMAPs. Let’s explore the details.

Understanding FODMAPs and IBS

FODMAPs, which stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols, are short-chain carbohydrates that some people find difficult to digest. For those with IBS, consuming high-FODMAP foods can lead to unpleasant symptoms like bloating, gas, and abdominal pain.

These carbohydrates are found in a variety of foods, and their impact on IBS symptoms can vary from person to person. Some people might tolerate certain FODMAPs better than others. Understanding which mushrooms are high or low in FODMAPs can help you decide which to include in your diet.

The FODMAP Content of Different Mushrooms

High FODMAP Mushrooms:

  • Button Mushrooms: These are commonly used in cooking but unfortunately, they are high in FODMAPs. Consuming them might trigger IBS symptoms.
  • Shiitake Mushrooms: Fresh shiitake mushrooms are also high in FODMAPs, specifically due to their mannitol content. Dried shiitake mushrooms, however, can be consumed in small amounts.
  • Enoki Mushrooms: These delicate mushrooms are popular in Asian cuisine but are high in FODMAPs.
  • Portobello Mushrooms: Known for their meaty texture, portobellos are high in FODMAPs and can cause symptoms if you have IBS.
  • Dried Porcini Mushrooms: These are high in FODMAPs when consumed in large quantities. However, a small amount might be tolerated.

Low FODMAP Mushrooms:

  • Oyster Mushrooms: These are one of the best options if you’re following a low-FODMAP diet. They are low in FODMAPs even in larger servings.
  • Canned Champignon (Button) Mushrooms: The canning process reduces the FODMAP content, making them a suitable option.
  • Porcini Mushrooms: In small amounts, these mushrooms are low in FODMAPs and can be included in your diet.
  • Shiitake Mushrooms (Dried): When dried, shiitake mushrooms are low in FODMAPs, but be cautious with the serving size.

Mushroom Supplements for IBS Relief

Due to the high FODMAP content in many types of mushrooms, some people with IBS choose to use mushroom supplements to gain the benefits without triggering symptoms. Supplements can provide concentrated doses of beneficial compounds found in mushrooms, allowing you to enjoy their health benefits while managing IBS more effectively.

Types of Mushroom Supplements:

  • Capsules: These are easy to consume and offer precise dosing. However, some may contain fillers or additives, so it’s essential to choose high-quality brands.
  • Liquid Extracts: Known for their potency and easy absorption, liquid extracts can be added to foods and drinks. They often have a strong taste, which some people might find unpleasant.
  • Powdered Supplements: These are versatile and can be mixed into smoothies, soups, or other dishes. They offer a robust profile of essential vitamins and minerals.

Recommended Varieties:

  • Reishi: This mushroom has strong anti-inflammatory properties, making it beneficial for reducing gut inflammation.
  • Lion’s Mane: Known for enhancing nerve growth, it can help soothe gut inflammation and improve overall digestive health.
  • Cordyceps: This mushroom has anti-inflammatory and adaptogenic properties, which can help manage stress and inflammation.

Nutritional Benefits of Mushrooms for IBS

Mushrooms aren’t just low or high in FODMAPs; they also offer a wealth of nutrients that can benefit anyone, including those with IBS.

Vitamins and Minerals:

  • B Vitamins: Mushrooms are rich in B vitamins such as riboflavin (B2), niacin (B3), and pantothenic acid (B5). These vitamins are crucial for energy production and brain health.
  • Selenium: This mineral has antioxidant properties that protect cells from damage and support immune function.
  • Potassium: Essential for heart and muscle function, potassium also helps regulate blood pressure.
  • Copper: Necessary for the formation of red blood cells and maintaining healthy bones and nerves.

Dietary Fibre:

Mushrooms provide dietary fibre, which aids in digestion and promotes gut health. Fibre can help manage IBS by regulating bowel movements and reducing the risk of constipation.

Protein Content:

Mushrooms are a good source of protein, providing essential amino acids that the body needs for growth and repair. This can be particularly beneficial if you’re trying to maintain a balanced diet.

Health Benefits of Mushrooms Beyond IBS

Mushrooms offer several health benefits beyond managing IBS symptoms. Their unique compounds can support overall well-being in various ways.

Anti-inflammatory Properties:

Certain types of mushrooms, like Reishi and Maitake, contain bioactive compounds with powerful anti-inflammatory effects. This can be beneficial if you experience inflammation in the gut, a common issue for people with IBS.

Gut Health:

Mushrooms are a natural source of prebiotics, which feed the beneficial bacteria in your gut. This can help improve gut health and potentially alleviate IBS symptoms. Prebiotic fibres in mushrooms like Shiitake and Maitake can promote the growth of these good bacteria.

Stress Management:

Stress can exacerbate IBS symptoms, and mushrooms such as Lion’s Mane and Cordyceps have adaptogenic properties that help manage stress. These mushrooms can support your body’s response to stress, indirectly benefiting your IBS symptoms.

Potential Risks and Considerations

While mushrooms offer many benefits, there are potential risks and considerations to keep in mind.

Allergies and Sensitivities:

Some people might have allergies or sensitivities to mushrooms, which can exacerbate IBS symptoms. Symptoms of an allergy can include hives, itching, swelling, nausea, vomiting, diarrhoea, and difficulty breathing. If you suspect you have a mushroom allergy, it’s essential to avoid all types and consult with a healthcare professional.

Portion Control:

Even low-FODMAP mushrooms should be consumed in moderation. Overeating can still lead to digestive discomfort. Stick to recommended serving sizes to avoid any potential flare-ups.

By understanding the different types of mushrooms and their FODMAP content, you can make informed dietary choices that help manage your IBS symptoms. Incorporating the right mushrooms into your diet, or using supplements, can provide nutritional benefits and support overall gut health. Always consult with a healthcare professional to tailor your diet and supplement use to your specific needs.

Variety and Individual Responses:

It's important to note that individual responses to different mushroom varieties can vary. What works for one may not work for another. The trial-and-error approach is often necessary to determine which mushrooms are safe for you to consume.


Mushrooms can be a nutritious addition to your diet, offering numerous health benefits and a potential aid in managing IBS symptoms. By understanding which mushrooms are high or low in FODMAPs, you can make informed choices that support your digestive health. Additionally, mushroom supplements provide a convenient way to incorporate these beneficial compounds into your diet. With the right approach, you can enjoy the health benefits of mushrooms while managing your IBS effectively.
