Mushrooms are a versatile ingredient, but not all are suitable for a low-FODMAP diet. FODMAP stands for Fermentable Oligo-, Di-, Mono-saccharides, and Polyols—types of carbohydrates that can cause digestive issues in some people. While some mushrooms are low FODMAP, others are high in mannitol, a type of polyol, and may trigger discomfort. White mushrooms, also known as button mushrooms, are high in FODMAPs, specifically mannitol and fructans, and should be avoided or limited on a low-FODMAP diet. However, canned white button mushrooms are generally considered low FODMAP due to the leaching of FODMAPs into the canning liquid, making them more gut-friendly.

What You'll Learn

Fresh white button mushrooms are high FODMAP
Fresh white button mushrooms are high in FODMAPs, specifically mannitol and fructans, which are types of polyols. Polyols are a type of FODMAP, which stands for Fermentable Oligo-, Di-, Mono-saccharides, and Polyols. The process of fermentation involves the breakdown of undigested carbs by gut bacteria, which produces gas and can cause bloating and discomfort.
White button mushrooms, also known as champignon mushrooms, are considered high-FODMAP foods. This means that they should be avoided or limited, especially during the elimination phase of a low-FODMAP diet, unless a safe serving size is known.
However, it is important to note that not all mushrooms are high in FODMAPs. For example, canned white button mushrooms are considered low-FODMAP due to the canning process, where the FODMAPs leach out into the canning liquid, reducing the overall FODMAP content of the mushrooms. Other types of low-FODMAP mushrooms include oyster mushrooms, which are known for their mild and delicate flavour, and dried shiitake mushrooms, in servings of up to two mushrooms.
The FODMAP content of mushrooms can vary, and some individuals with IBS may be able to tolerate certain FODMAPs without experiencing symptoms. It is always recommended to consult a specialised dietitian for tailored guidance and to determine individual tolerance levels.

Canned white button mushrooms are low FODMAP
Canned white button mushrooms are low in FODMAPs, but their fresh counterparts are not. FODMAP stands for Fermentable Oligo-, Di-, Mono-saccharides, and Polyols. These are carbohydrates that can cause digestive issues in some people, such as those with IBS.
FODMAP testing reveals that not all mushrooms are high in FODMAPs. For instance, canned white button mushrooms are suitable for a low-FODMAP diet. This is because the canning process causes water-soluble FODMAPs to leach out into the water, reducing the overall FODMAP content of the mushrooms. Canned white button mushrooms have a mild, slightly salty flavour due to the brine in which they are packed. Their texture is softer and more uniform than that of fresh mushrooms, and they are tender, sometimes with a slightly rubbery texture depending on the canning process and storage time.
Canned white button mushrooms are convenient and versatile, making them an easy addition to a low-FODMAP diet. They can be used in soups, stews, pasta or rice dishes, salads, stir-fries, casseroles, sauces, and gravies. They are also popular in Asian cuisine. It is important to note that serving size matters, as certain low-FODMAP mushrooms can become high FODMAP in larger serving sizes.
However, fresh white button mushrooms are high in the FODMAP mannitol and moderate in fructans, so they should be avoided or consumed in moderation if you are on a low-FODMAP diet. It is recommended that you leave them out of your diet until you are ready to test your tolerance to mannitol.

White mushrooms are also called champignon mushrooms
White mushrooms, also known as button mushrooms or champignon mushrooms, are high in FODMAP for mannitol. They are therefore not recommended for people on a low-FODMAP diet unless they are testing their tolerance to mannitol. However, canned champignon mushrooms are low FODMAP at a serving size of 6 mushrooms. These mushrooms are popular in Asian cuisine and are often used in stir-fries, salads, and omelets. They can also be combined with rice and the green portions of scallions.
Champignon mushrooms, also known as Agaricus bisporus, are one of the most commonly consumed mushrooms worldwide. They are cultivated in more than 70 countries and are available in both white and brown varieties. The white mushroom was discovered in 1925 in Coatesville, Pennsylvania, and has since become a popular food item due to its attractive appearance. It is also known as the cultivated mushroom or the common mushroom.
The taxonomic history of the common mushroom is quite complicated. It was first described as a variety of Agaricus campestris by English botanist Mordecai Cubitt Cooke in 1871. However, over time, it was reclassified and eventually given the scientific name Agaricus bisporus in 1946.
White mushrooms, specifically raw white button mushrooms, fall into the moderate FODMAP category. This means that while they may not be suitable for a strict low-FODMAP diet, they can be consumed in moderation by those sensitive to FODMAPs. It is always recommended to consult with a specialized dietitian to determine the best dietary approach for your individual needs.

White button mushrooms are high in mannitol and fructans
White button mushrooms, also known as champignon mushrooms, are high in mannitol and moderate in fructans. This means that they are not suitable for a low-FODMAP diet, at least during the elimination phase. However, canned white button mushrooms are low FODMAP because the water-soluble FODMAPs leach out into the water, reducing the overall FODMAP content.
FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols, which are short-chain carbohydrates that are poorly absorbed in the small intestine and can cause digestive issues for some people. Mannitol and fructans are types of polyols and oligosaccharides, respectively, which are found in high quantities in white button mushrooms.
During the low-FODMAP diet's elimination phase, it is generally recommended to avoid high-FODMAP foods. However, once this phase is complete, it is possible to reintroduce high-FODMAP foods like white button mushrooms and test your tolerance to them. It is important to work with a specialized dietitian to determine your specific dietary needs and navigate which mushrooms are suitable for you.
It is worth noting that not all mushrooms are high in FODMAPs. For example, oyster mushrooms, canned champignon mushrooms, and dried shiitake mushrooms are considered low FODMAP. Additionally, the serving size can impact the FODMAP content, with some low-FODMAP mushrooms becoming high FODMAP in larger servings.
In conclusion, while white button mushrooms are high in mannitol and fructans, making them generally unsuitable for the elimination phase of a low-FODMAP diet, there are alternative mushroom options available, and it is possible to test your tolerance to them at a later stage.

Other low-FODMAP mushrooms include oyster and shiitake mushrooms
While white mushrooms are considered high FODMAP, there are several other types of mushrooms that are suitable for a low-FODMAP diet.
Oyster mushrooms, for instance, are low FODMAP and can be enjoyed in any amount. They have a delicate, velvety texture and a mild, slightly sweet flavour with hints of anise. They are incredibly versatile and can be stir-fried, grilled, roasted, sautéed, or used in soups and stews.
Shiitake mushrooms, on the other hand, are a bit more nuanced. When fresh, they are considered high FODMAP due to their high polyol mannitol content. However, dried shiitake mushrooms are low FODMAP at a serving size of up to two mushrooms. They offer a rich umami flavour and are quite versatile, making them a staple in many cuisines, especially in Asia.
In addition to oyster and shiitake mushrooms, canned champignon or button mushrooms are also considered low FODMAP. The canning process causes the water-soluble FODMAPs to leach out into the water, making the mushrooms themselves more gut-friendly. A serving size of half a cup for canned champignons or 250 grams for canned button mushrooms is considered low FODMAP.
It's important to note that while these mushrooms are generally considered low FODMAP, individual tolerance levels may vary. It's always a good idea to consult a specialised dietitian to determine which mushrooms are suitable for your specific dietary needs.
