FODMAP is an acronym for Fermentable Oligo-, Di-, Mono-saccharides and Polyols, which are short-chain carbohydrates that the small intestine cannot efficiently absorb. Mushrooms are versatile ingredients, but not all types are FODMAP-friendly. Some mushrooms, like button mushrooms, are high in FODMAPs, while others, like oyster mushrooms, are low in FODMAPs even in larger servings. Serving size is crucial, as some mushrooms can be FODMAP-friendly in small quantities but trigger symptoms in larger portions. Additionally, preparation methods like canning can reduce the FODMAP content of mushrooms. For those who prefer mushroom extracts or powders for medicinal purposes, the concentrated form and smaller serving sizes may be suitable for a low-FODMAP diet. However, individual tolerance varies, and it is essential to understand your body's response to different mushrooms and their preparations.

What You'll Learn
FODMAPs are fermentable oligo-, di-, mono-saccharides and polyols
FODMAP is an acronym that stands for Fermentable Oligo-, Di-, Mono-saccharides and Polyols. These are short-chain carbohydrates that the small intestine cannot absorb efficiently. FODMAPs are found in foods such as wheat, garlic, dairy products, and artificial sweeteners, and can trigger symptoms in people with irritable bowel syndrome (IBS).
Oligo-, di-, and mono-saccharides are different types of sugars. Oligosaccharides include fructans, which are found in agave, wheat, garlic, and asparagus. Monosaccharides include fructose, or fruit sugar, which is often used to sweeten foods and drinks. Polyols, meanwhile, are sugar alcohols such as sorbitol, xylitol, and maltitol, commonly found in soda, gum, and mints.
The FODMAP content of foods is important for people with IBS, as they can trigger symptoms such as abdominal pain, bloating, and diarrhoea. A low-FODMAP diet is often recommended for managing IBS symptoms, and involves limiting high-FODMAP foods and identifying individual triggers. Serving size also plays a role, as smaller portions of high-FODMAP foods may be tolerable for some people.
Mushrooms, for example, are a popular ingredient but can be high in FODMAPs, specifically mannitol, a type of polyol. However, not all mushrooms are equally high in FODMAPs, and some varieties can be enjoyed in moderation on a low-FODMAP diet. These include oyster mushrooms, canned champignon mushrooms, and dried shiitake mushrooms. Medicinal mushroom powders and extracts, typically consumed in small servings, are also considered safe for people on a low-FODMAP diet.

Mushrooms are high in FODMAPs due to polyol content
FODMAP is an acronym for Fermentable Oligo-, Di-, Mono-saccharides and Polyols. These are short-chain carbohydrates that the small intestine cannot efficiently absorb, which can cause symptoms in people with IBS.
Mushrooms are a type of fungus but are commonly classified as vegetables. They are biologically different from plant- and animal-derived foods. They are the fruiting bodies of macroscopic filamentous fungi that grow above the ground. They are a popular ingredient in cooking and are most commonly used in European, Asian, and South American cuisines.
Mushrooms are a source of FODMAPs, specifically polyols, and most types of mushrooms contain the FODMAP mannitol. Mannitol is a sugar alcohol that can contribute to IBS symptoms due to its role as a fermentable carbohydrate. It is also present in other foods, including watermelon, cauliflower, celery, butternut squash, sweet potato, and mange tout.
However, not all mushrooms have the same FODMAP content, and some varieties are considered low FODMAP. For example, oyster mushrooms are low in FODMAPs and can be enjoyed by people following a low-FODMAP diet, even in larger servings. Canned champignons (or canned white button mushrooms) are also low in FODMAPs, as the canning process causes the FODMAPs to leach into the canning liquid, making the mushrooms more gut-friendly. It is important to drain and rinse these mushrooms before use. Additionally, dried shiitake mushrooms are considered low FODMAP in small servings.

Serving size dictates whether a food is low FODMAP
FODMAP is an acronym for Fermentable Oligo-, Di-, Mono-saccharides and Polyols. These are short-chain carbohydrates that the small intestine cannot efficiently absorb. FODMAPs include fructose (fruit sugar), fructans (found in agave, wheat, garlic, and asparagus), lactose (found in dairy products), and artificial sweeteners (like sorbitol, xylitol, and maltitol).
The low FODMAP diet limits these carbohydrates to prevent digestive issues. However, it's important to note that not all FODMAPs may trigger symptoms in everyone. Tolerance levels vary from person to person, so it's essential to understand your body and its unique needs.
When it comes to mushrooms, the serving size plays a crucial role in determining whether they are suitable for a low FODMAP diet. Mushrooms naturally contain FODMAPs, particularly mannitol, but the amount can vary depending on the type of mushroom and the serving size.
For example, let's consider some common types of mushrooms:
- Button mushrooms: Fresh button mushrooms are considered high in FODMAPs. However, canned button mushrooms, also known as canned champignon mushrooms, are low FODMAP in half-cup servings. The canning process reduces FODMAP content as they leach into the brine.
- Portobello mushrooms: These mushrooms, which are mature button mushrooms, are high in FODMAPs even in half-serving sizes. They contain notable levels of polyols, so they may not be suitable for a strict low-FODMAP diet.
- Oyster mushrooms: Fresh oyster mushrooms are low FODMAP and can be enjoyed in larger servings. Canned oyster mushrooms are also low FODMAP in one-cup servings.
- Shiitake mushrooms: Fresh shiitake mushrooms are high in polyol-mannitol, making them less suitable for a low-FODMAP diet. However, dried shiitake mushrooms can be tolerated in smaller quantities. A serving of 7 grams is considered low FODMAP.
- Dried porcini mushrooms: These mushrooms can be tricky. A quarter-cup serving is low FODMAP, while a half-cup serving contains moderate FODMAP levels.
- Enoki mushrooms: These mushrooms, commonly used in Asian cuisine, have high FODMAP levels even in small servings.
It's important to note that medicinal mushroom powders and extracts are concentrated forms, and their serving sizes are typically small. Therefore, they generally do not pose issues regarding FODMAP content for regular-sized servings.
To summarize, serving size is indeed a critical factor in determining whether a food is low FODMAP. The tolerance levels for FODMAPs vary across individuals, so it's important to understand your body's unique needs and adjust your diet accordingly.

Some mushroom varieties are low FODMAP
FODMAP stands for Fermentable Oligo-, Di-, Mono-saccharides and Polyols. In simpler terms, it refers to short-chain carbohydrates that the small intestine cannot efficiently absorb. FODMAPs include fructose, fructans, lactose, and sugar alcohols like sorbitol, xylitol, and maltitol.
Some mushroom varieties are indeed low FODMAP. Monash University in Australia is a leading research centre studying the FODMAP properties of foods. According to their studies, certain mushrooms are low FODMAP even in multiple servings. Here are some examples:
- Canned Champignon or white mushrooms: These are low FODMAP in half-cup or 1/2 cup serves. The canning process lowers their FODMAP content as the mannitol and fructans leach into the brine. Be sure to drain and rinse them before use.
- Fresh Oyster mushrooms: These are low FODMAP in 1-cup or 75-gram serves. They have a unique savoury flavour and can be pan-fried, grilled, or added to various dishes.
- Dried Porcini mushrooms: These are low FODMAP in smaller servings, such as a quarter or half-cup, or 1 tablespoon. Above these serving sizes, they are high in the FODMAP mannitol.
- Dried Black Chanterelle mushrooms: A serving of 3 grams or 1/8 cup is low FODMAP. Larger servings contain moderate amounts of sorbitol, a type of FODMAP.
- Canned White Button mushrooms in brine: These are low FODMAP in 1-cup or 75-gram serves.
It's important to note that serving size plays a crucial role in determining whether a food is acceptable on a low FODMAP diet. Additionally, individual tolerance may vary, and it's always recommended to consult reliable sources and medical professionals for specific dietary advice.

Medicinal mushroom powder is a concentrated mushroom extract
FODMAP is an acronym for Fermentable Oligo-, Di-, Mono-saccharides and Polyols. These are short-chain carbohydrates that the small intestine cannot efficiently absorb. Mushrooms are a versatile ingredient, but they rank high on the FODMAP scale due to their polyol content.
However, some mushrooms are still low-FODMAP choices, even in multiple servings. For example, a serving of 7 grams of button mushrooms is low FODMAP, while 10 grams contains a moderate amount of mannitol. Similarly, a serving of 7 grams of dried shiitake mushrooms is low FODMAP, while 17 grams contains a moderate amount of mannitol.
Medicinal mushrooms have been used to promote well-being and longevity in traditional Chinese medicine. For example, Ganoderma lucidum, or reishi, has been used to treat various types of cancer. Modern research has also shown that mushroom extracts have anti-inflammatory properties and can suppress the development of colorectal adenomas and precancerous lesions in the large bowel.
