Mushrooms are a delicious and nutritious addition to many dishes, but they can also be the culprit behind some uncomfortable gas. Mushrooms are fungi that contain a unique fibre called beta-glucan, which can be fermented by gut bacteria, leading to flatulence and other gastrointestinal issues. The cell walls of mushrooms contain chitin, an indigestible fibre, as well as hard-to-digest carbohydrates like mannitol and trehalose. These substances are challenging for the intestines to break down, resulting in gas and even diarrhoea for some individuals. The amount and type of mushrooms consumed also play a role in their gassy effects, with certain varieties like button, portobello, and shiitake mushrooms being more likely to trigger GI problems. While mushrooms are not the only gassy food, their consumption can be a contributing factor to bloating and discomfort.

What You'll Learn
Mushrooms are a FODMAP food
However, not everyone experiences these issues with mushrooms. Some people with irritable bowel syndrome (IBS) may find that mushrooms do not cause any problems for them, while others without IBS may have a sensitivity or intolerance to mushrooms. It is important to note that every individual has a unique gut environment shaped by various factors such as diet, environment, stress, and medications.
If you experience gas or bloating after consuming mushrooms, you can try reducing the portion size or switching to lower-FODMAP mushrooms, such as oyster mushrooms. Canned mushrooms are also a good low-FODMAP substitute. It is worth noting that the way mushrooms are prepared and cooked can also affect their digestibility. Raw mushrooms, for example, are not advisable to eat as they are difficult to digest and may contain toxins or infections.
Additionally, mushrooms contain a type of fibre called beta-glucan, which has been linked to potential mood benefits. An observational study found that those who consumed a small amount of mushrooms daily had a lower chance of depression over nine years compared to those who did not eat mushrooms.
In summary, mushrooms are a FODMAP food that can potentially cause gas and other gastrointestinal issues, but the effects vary from person to person. It is important to listen to your body and adjust your mushroom consumption accordingly.

Mushrooms contain mannitol, a sugar alcohol
Mushrooms are a well-known gassy food, causing flatulence and bloating in some people. They are a FODMAP-containing food, which stands for fermentable oligosaccharides, disaccharides, monosaccharides and polyols. Mushrooms contain mannitol, a sugar alcohol from the polyol family, which is found in many fruits and vegetables. Mannitol is poorly absorbed in the small intestine and can cause GI disturbances, as it is difficult for the intestines to digest.
Mushrooms also contain indigestible dietary fibre, chitin, which is a carbohydrate that is strenuous for the intestines to break down. This can lead to flatulence and diarrhoea. The thick cell walls of mushrooms mean that they are difficult to digest, and the protein in the cells can only be absorbed with thorough chewing.
Some mushrooms are safer to eat raw, such as button, shiitake, oyster, and king trumpet mushrooms, but even these varieties are challenging to digest in large quantities. Experts recommend consuming no more than 200-300g of fresh mushrooms per week to avoid any adverse effects.
The gassiness caused by mushrooms is not limited to those with IBS or other gastrointestinal disorders. Anyone can have a sensitivity or intolerance to mushrooms, and the effects can vary from person to person. If you notice increased flatulence after consuming mushrooms, you can try reducing your portion size or switching to lower-FODMAP mushrooms, such as oyster mushrooms.

Mushrooms are high in FODMAPs like fructans
Mushrooms are a FODMAP-containing food. FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. These are groups of foods that are easily fermented by bacteria found in the large intestine. When foods are fermented in the gut, they can cause gas, bloating, abdominal pain, and bowel changes, especially in people who are sensitive to these types of foods.
Mushrooms are high in FODMAPs like mannitol, sorbitol, and fructans, which can cause symptoms if you have IBS. Mannitol is a polyol (a sugar alcohol) that can contribute to IBS symptoms due to its role as a fermentable carbohydrate. It is poorly absorbed in the small intestine and tends to cause more GI disturbances than other natural, long-chain sugars. It is present in other foods, including watermelon, cauliflower, celery, butternut squash, sweet potato, and mange tout.
Fructans are another type of FODMAP that is found in mushrooms, particularly in fresh button mushrooms. Fructans are also present in other vegetables like artichokes, garlic, leeks, onions, and spring onions, as well as in grains and cereals like wholemeal bread, rye bread, muesli, wheat pasta, and rye crispbread.
While mushrooms are high in FODMAPs, there are some types of mushrooms that are low in FODMAPs and can be enjoyed by people with IBS or those following a low-FODMAP diet. These include oyster mushrooms, canned white button mushrooms, and shimeji mushrooms. Canned mushrooms are lower in FODMAPs because the water-soluble FODMAPs leach out into the water, making them a good substitute when cooking.
It is important to note that not everyone will experience gas or other GI symptoms after eating mushrooms. Individual tolerance varies, and some people may be able to eat mushrooms without any issues. However, for those who are sensitive to FODMAPs or have IBS, mushrooms can be a trigger for gas and other digestive problems.

Mushrooms are difficult to digest
Mushrooms are a FODMAP-containing food, which stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. FODMAPs are groups of foods easily fermented by bacteria in the large intestine, producing gas, bloating, abdominal pain, and bowel changes. Some mushrooms, like button, portobello, and shiitake, are high-FODMAP foods that can trigger gastrointestinal issues.
The difficulty in digesting mushrooms also depends on the quantity consumed. Even edible mushrooms can cause digestive problems if consumed in large quantities. The stomach needs up to 5 hours to digest mushrooms, and they should be cooked to destroy potential toxins and avoid the risk of infection. Raw mushrooms are challenging to digest in large amounts, and experts recommend consuming no more than 200-300g of fresh mushrooms weekly.
Additionally, the digestibility of mushrooms varies across individuals. Some people may have a sensitivity or intolerance to mushrooms, leading to flatulence, diarrhoea, and other gastrointestinal symptoms. The impact of mushrooms on digestion is influenced by various factors, including an individual's gut environment, stress levels, medications, and overall health.
While mushrooms can be challenging to digest for some, they offer nutritional benefits. They contain proteins, vitamins, and minerals comparable to those in various vegetables. They are also a source of beta-glucan fibre, which has been linked to improved heart health and potential mood benefits.

Not all mushrooms are gassy
Mushrooms are a FODMAP-containing food, which stands for fermentable oligosaccharides, disaccharides, monosaccharides and polyols. FODMAP-containing foods are easily fermented by bacteria found in the large intestine, which can cause gas, bloating, abdominal pain and bowel changes, especially in people who are sensitive to these types of foods.
However, not all mushrooms are gassy. While some mushrooms contain high amounts of mannitol, a sugar alcohol that is poorly absorbed in the small intestine and can cause GI disturbances, others contain lower levels of mannitol or none at all. For example, oyster mushrooms contain trehalose, which only causes problems for people who lack the digestive enzyme trehalase. Shiitake mushrooms may also be less likely to cause gas, as some people who experience gas after eating other mushrooms find that shiitake mushrooms do not have the same effect.
Additionally, the gassiness of mushrooms can depend on the individual. While some people may find that mushrooms cause gas and bloating, others may be able to eat them without any issues. This is because every human has a unique gut environment that is shaped by various factors, such as diet, environment, stress, and medications. Therefore, the foods that work for one person's gut may not work for another's.
It is worth noting that the way mushrooms are prepared and consumed can also affect their gassiness. The cell walls of mushrooms are thick, making it difficult for the protein in the cells to be absorbed. Therefore, it is important to chew mushrooms well to facilitate digestion. Eating raw mushrooms, especially wild mushrooms, is not recommended as they may contain toxins or be infected by fox tapeworm. Cooking mushrooms helps to destroy these harmful substances. Experts also recommend consuming no more than 200-300g of fresh mushrooms per week to avoid the risk of over-exposure to harmful substances that accumulate in mushrooms from the environment.
