Mushrooms are a healthy and delicious addition to many dishes, but they can also cause some unwanted side effects. Eating mushrooms can lead to gas and bloating, which may be surprising and uncomfortable for some people. Pickling is a common way to prepare and preserve mushrooms, but will consuming pickled mushrooms have the same gassy effects as eating them fresh? Let's explore the connection between mushrooms and gas, and whether pickling makes a difference.
| Characteristics | Values |
|---|---|
| Do pickled mushrooms cause gas? | Yes, mushrooms are a FODMAP-containing food, which stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. These are groups of foods that are easily fermented by bacteria found in the large intestine. |
| Why do mushrooms cause gas? | Mushrooms contain sugars that are difficult to digest, such as mannitol, a sugar alcohol from the polyol family. Mannitol is poorly absorbed in the small intestine and can cause GI disturbances. Additionally, mushrooms have a high fiber content, and overconsumption can lead to an overload of fiber in the digestive system, resulting in gas and bloating. |
| How to reduce gas from mushrooms | Eat smaller portions of mushrooms, switch to lower-FODMAP mushrooms like oyster mushrooms, or choose canned mushrooms. Cooking mushrooms thoroughly, especially when eating them with other gassy foods, can also help break down complex carbohydrates and reduce gas formation. |

What You'll Learn
Pickled mushrooms are a FODMAP food
Pickled mushrooms can cause gas and bloating, and this is due to their high fibre content. Consuming too many mushrooms can cause an overload of fibre in the digestive system, leading to discomfort and gas. Some mushrooms, such as shiitake, are high in FODMAPs as they contain high amounts of polyol mannitol. FODMAP stands for Fermentable Oligo-, Di-, Mono-saccharides and Polyols, which are short-chain carbohydrates that the small intestine cannot absorb efficiently.
According to Monash FODMAP studies, not all varieties of mushrooms are high in FODMAPs. Some are still low FODMAP choices even in multiple servings. For example, canned champignon mushrooms are a wonderful choice in moderation. According to Monash’s research, a full serving of champignon tests as low FODMAP. However, button mushrooms are a no-no for all low FODMAP recipes and diets. When tested at both a half and full serving, they still contain high levels of polyols.
The FODMAP content of foods, like button mushrooms, will leach into any liquid in the dish and raise the FODMAP content of the whole meal. Therefore, it is best to avoid eating high FODMAP foods during the first phase of a low FODMAP diet. Parasol mushrooms are currently untested, so it is recommended to test your tolerance levels.
One way to reduce the risk of gas and bloating after consuming mushrooms is to cook them thoroughly. Marinating the mushrooms in acid, like lemon juice or vinegar, may also help break down the complex carbohydrates in them. Eating smaller portions at a time could also help your digestive system to digest the mushrooms more easily.

Mannitol in mushrooms can cause gas
Pickled mushrooms can cause gas due to the presence of mannitol, a type of carbohydrate called a sugar alcohol or polyol. Mannitol occurs naturally in fresh mushrooms, brown algae, tree bark, and most fruits and vegetables. It is also commercially produced and added to various food products, including chocolate coatings, confections, chewing gum, and packaged foods.
Mannitol contains about 60% fewer calories than sugar and is half as sweet. While it is generally safe, consuming excessive amounts of mannitol can cause gastrointestinal discomfort, including gas, bloating, and diarrhea. This is because mannitol is only partially absorbed by the body, with about one-third of it being metabolized by gut bacteria. The unabsorbed portion of mannitol draws water into the small intestine, leading to increased stool volume, diarrhea, and gas.
People with irritable bowel syndrome (IBS) are particularly sensitive to mannitol due to visceral hypersensitivity, which results in an increased awareness of changes in the passing of gas, food, and liquid through the gut. For this reason, those following a low FODMAP (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) diet are advised to monitor their intake of mannitol-containing foods, including mushrooms.
To reduce the risk of mannitol-related gas, it is recommended to be mindful of portion sizes and consume small portions of low FODMAP foods. Additionally, cooking mushrooms thoroughly and marinating them in acid can help break down complex carbohydrates, making them more easily digestible.
In summary, mannitol in mushrooms can cause gas, especially when consumed in excessive amounts or by individuals with IBS or other digestive sensitivities. However, by managing portion sizes, cooking methods, and incorporating low FODMAP foods gradually, it is possible to mitigate the gas-causing effects of mannitol in mushrooms.

Chitin in mushrooms is hard to digest
Pickled mushrooms can cause gas due to the presence of chitin, a complex carbohydrate that is hard for the body to digest. Chitin is a type of dietary fibre that forms the cell walls of mushrooms. These cell walls are thick, which means that the protein in the cells can only be absorbed if the mushrooms are thoroughly chewed.
Chitin is a complex carbohydrate that is difficult for the intestines to digest. The indigestibility of chitin is one of the reasons why mushrooms are tough on the stomach. The stomach needs up to 5 hours to digest mushrooms. Chitin is a type of fibre that can cause gas and bloating when it is not completely digested in the stomach and small intestine. Instead, it passes into the large intestine, where bacteria help break it down, creating gas in the process.
Mushrooms are a FODMAP-containing food, which stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. FODMAPs are groups of foods that are easily fermented by bacteria in the large intestine, leading to gas, bloating, and other digestive issues. Mannitol, a sugar alcohol from the polyol family, is commonly found in mushrooms and can cause flatulence and diarrhoea. This is because mannitol is poorly absorbed in the small intestine, leading to GI disturbances.
The digestibility of mushrooms also depends on the type of mushroom, the cooking method, and the state of the mushroom. Eating mushrooms raw is more difficult than eating them cooked because cooking breaks down complex carbohydrates like chitin. Eating smaller portions of mushrooms at a time can also help reduce the risk of gas and bloating. Marinating mushrooms in acid, such as lemon juice or vinegar, can also help break down complex carbohydrates.

Raw mushrooms are more likely to cause gas
Pickled mushrooms may cause gas due to the presence of mannitol, a natural sugar that can act as a mild laxative. However, raw mushrooms are more likely to cause gas due to their high fibre content and the presence of complex carbohydrates.
Mushrooms are a rich source of nutrients, including vitamins, minerals, and antioxidants. They also contain high levels of mannitol, which is a sugar alcohol that can cause gas and diarrhoea. While mannitol is present in both raw and pickled mushrooms, the pickling process may slightly reduce its concentration, making pickled mushrooms less likely to cause gas.
Raw mushrooms have a high fibre content, which can lead to an overload of fibre in the digestive system, resulting in gas and bloating. Cooking mushrooms helps break down complex carbohydrates, making them more easily digestible. Pickling mushrooms is a form of cooking, as the heat from the pickling process can help soften the mushrooms and partially break down these complex carbohydrates.
Additionally, the type of mushroom and the state of consumption can affect digestibility. Some mushrooms, such as oyster mushrooms, contain lower levels of mannitol and other sugars that are difficult to digest. Consuming raw mushrooms may also increase the risk of consuming toxins or bacteria that are only destroyed through cooking. Therefore, raw mushrooms are more likely to cause gas and other digestive issues compared to pickled mushrooms.
To minimize the risk of gas from consuming mushrooms, it is recommended to cook them thoroughly, choose lower-FODMAP varieties such as oyster mushrooms, and consume smaller portions. Pickling mushrooms or marinating them in acid can also help break down complex carbohydrates, making them easier to digest and potentially reducing the likelihood of experiencing gas.
In summary, while pickled mushrooms may still cause gas due to the presence of mannitol, raw mushrooms are generally more likely to cause gas due to their high fibre content and the presence of complex carbohydrates that are more effectively broken down during the pickling or cooking process.

Tips to reduce gas from pickled mushrooms
Pickled mushrooms can cause gas due to their high fibre content and a complex carbohydrate called chitin, which is difficult for the body to digest. Here are some tips to reduce gas from consuming pickled mushrooms:
Choose the right type of mushroom
Some mushrooms, like shiitake and oyster mushrooms, have lower mannitol levels and are easier to digest than others. Oyster mushrooms, for instance, have the lowest levels of mannitol, while button mushrooms are more likely to cause gas and bloating due to their high mannitol content.
Prepare and cook them well
Raw mushrooms can be harder to digest than cooked ones. Cooking mushrooms breaks down complex carbohydrates and tough cellular structures, making them more easily digestible. Make sure to cook them thoroughly, and consider cooking them in water to reduce their sugar content and bloat potential.
Eat smaller portions
Consuming large quantities of mushrooms can cause an overload of fibre in the digestive system, leading to gas and discomfort. Eating smaller portions can help your digestive system handle the mushrooms more easily.
Marinate in acid
Soaking mushrooms in acid, such as lemon juice or vinegar, may help break down complex carbohydrates and make them easier to digest.
Chew slowly
Chewing your food slowly can help reduce gas and bloating. This is because the protein in mushroom cells can only be absorbed if you chew them well.
Avoid gas-inducing combinations
Pairing mushrooms with other hard-to-digest foods, such as beans, cruciferous vegetables, or carbonated drinks, can increase the likelihood of gas and bloating. Consuming mushrooms with easier-to-digest foods can reduce the chances of digestive discomfort.
Stay hydrated
Drinking water supports the digestive process. Make sure to stay well-hydrated when consuming foods that may be challenging to digest.
Try herbs and spices
Certain herbs and spices, such as ginger and peppermint, have a calming effect on the digestive system and may help alleviate symptoms of gas and bloating. Peppermint tea, in particular, can help deflate bloating.
Gentle exercise
Gentle exercise can help move gas through your system. However, vigorous exercise may have the opposite effect.
