Mushrooms are a type of vegetable that can be eaten cooked or raw. While they can be a pleasant addition to a meal, they can also be tough on the stomach. Some people lack the enzyme needed to break down trehalose, a carbohydrate found in mushrooms, which can lead to digestive issues such as flatulence and diarrhoea. Consuming wild mushrooms also carries the risk of poisoning, which can cause nausea, vomiting, and stomach pain. However, cooked mushrooms are recommended for diarrhoea, and they are generally safe to eat when properly prepared and consumed in moderate amounts.

What You'll Learn
Mushrooms can be tough on the stomach
Mushrooms are tasty and nutritious, but they can be tough on the stomach. Of the 10,000 known species of large mushrooms, only around 300 are edible. Even then, they can cause digestive issues. The cell walls of mushrooms are made of chitin, an indigestible fibre. Some people lack the enzyme needed to break down trehalose, another component of mushrooms. As a result, they may experience digestive problems like flatulence and diarrhoea.
Mushrooms also contain sugar alcohols that are challenging to digest, such as mannitol, found in common white mushrooms. Mannitol is poorly absorbed in the small intestine and often causes gastrointestinal disturbances. Other mushrooms, like oyster mushrooms, contain trehalose, which only becomes an issue if a person lacks the digestive enzyme trehalase.
The thick cell walls of mushrooms mean that the protein in the cells can only be absorbed with thorough chewing. The stomach needs up to five hours to digest mushrooms, and it is not advisable to eat them raw. Some mushrooms contain toxins that are only destroyed through cooking. Wild mushrooms may be infected with fox tapeworm, and even cultivated varieties can cause issues if they are too old or not cooked properly.
Experts recommend consuming no more than 200-300g of fresh mushrooms per week to avoid the risk of exposure to harmful substances that accumulate in mushrooms from the environment, such as pollutants and heavy metals.

Some mushrooms are poisonous
While mushrooms are generally safe to eat, it's important to be cautious as some mushrooms are poisonous and can cause serious health issues, or even death. Out of the 10,000 known species of large mushrooms, only about 300 are considered edible.
Mushroom poisoning occurs when toxic mushrooms are ingested, often due to misidentification as edible species. This misidentification can happen because some poisonous mushrooms closely resemble edible ones in colour and morphology. For example, the Amanita phalloides (or "death cap") mushroom resembles the Asian paddy-straw mushroom, Volvariella volvacea. Similarly, Amanita verna, also known as the "fool's mushroom" or "destroying angel," can be mistaken for button mushrooms or meadow mushrooms. Conocybe filaris, another toxic mushroom, has an innocent appearance and is often found on lawns in the Pacific Northwest.
The severity of mushroom poisoning can vary depending on factors such as the mushroom species, the amount ingested, individual susceptibility, and the presence of other confounding factors. Some mushrooms contain gastrointestinal irritants that cause vomiting and diarrhoea, which can sometimes require urgent medical care. Other mushrooms contain toxins that specifically target certain organs, such as the liver and kidneys, and can lead to severe damage or even death. For example, the Galerina marginata, also known as the "autumn skullcap," contains the same amatoxins as the deadly Amanita species.
To prevent mushroom poisoning, it is crucial to properly identify mushrooms before consumption. Mushroom gatherers should familiarise themselves with both edible and toxic mushroom species. Additionally, boiling, cooking, freezing, or processing may not always eliminate toxins, so it is generally not advisable to eat mushrooms raw.

Mushrooms are difficult to digest
Mushrooms also contain sugar alcohols that are challenging to digest, such as mannitol, which is found in common white mushrooms. Mannitol is poorly absorbed in the small intestine and can cause gastrointestinal disturbances. Some people lack the enzyme needed to break down trehalose, another sugar alcohol found in mushrooms, which can lead to severe digestive problems like flatulence and diarrhoea.
In addition, mushrooms can be contaminated with pollutants like radioactive substances or heavy metals, depending on where they are sourced. It is important to cook mushrooms properly, as some contain toxins that are only destroyed through cooking. Eating raw mushrooms may also increase the risk of ingesting harmful bacteria or parasites, such as the fox tapeworm.
While mushrooms can be a nutritious addition to the diet, providing protein, vitamins, and minerals, they should be consumed in moderation. Experts recommend limiting mushroom intake to no more than 200-300 grams of fresh mushrooms per week to avoid potential digestive issues and minimise exposure to harmful substances.

BRAT diet for upset stomach
Mushrooms are not the best food to eat when you have an upset stomach. They are often tough on the stomach due to the presence of chitin, a type of indigestible dietary fibre that forms the cell walls of mushrooms. Some people may lack the enzyme needed to break down trehalose, another substance found in mushrooms, which can lead to digestive problems like flatulence and diarrhoea. Raw mushrooms are especially hard to digest and may even contain toxins or be infected by parasites.
If you are experiencing an upset stomach, it is important to stay hydrated by drinking clear fluids such as water, broths, or diluted juices. You should also eat bland, easy-to-digest foods that will not irritate your stomach further. This is where the BRAT diet comes in. BRAT stands for Bananas, Rice, Applesauce, and Toast. These foods are starchy and low in fibre, which can help to bind loose stools. They are also low in fat and protein, making them less likely to upset your stomach or put stress on your digestive system. The BRAT diet was often recommended for nausea, vomiting, and diarrhoea due to its gentle nature on the stomach.
However, it is important to note that the BRAT diet is no longer widely recommended due to its restrictive nature and limited nutritional profile. While it may help relieve symptoms in the short term, it is not intended for long-term use. Instead, it is suggested to eat a bland diet that consists of a wider variety of foods to prevent undernourishment. Other soft fruits like avocado, pumpkin, canned fruit (packed in water), and melons can be included. Steamed or boiled vegetables such as carrots, green beans, potatoes, and squash are also gentle on the stomach. Low-fibre starches like white bread, white rice, saltine crackers, and instant oatmeal can be easily digested.
Remember, if you are experiencing diarrhoea, it is generally recommended to eat vegetables that have been cooked, as raw vegetables can be hard to digest. Removing seeds and skins is also advisable. Baked potatoes, bone broth, and ginger tea can be soothing for an upset stomach. It is also crucial to maintain proper hydration by drinking enough liquids, especially if you are experiencing vomiting or diarrhoea.

Bland foods are gentle on the stomach
An upset stomach is an umbrella term for all types of abdominal discomfort and changes in bowel movements. Symptoms of an upset stomach include constipation, diarrhoea, nausea, and cramps. It is important to maintain hydration by consuming clear fluids like water, broths, or diluted juices to replenish fluids lost through vomiting or diarrhoea.
In addition to the BRAT diet, other bland foods that can be gentle on the stomach include baked potatoes, pancakes and waffles made with white flour, and cornbread. It is also recommended to eat small meals throughout the day instead of three large meals.
Mushrooms are not typically recommended for an upset stomach as they can be tough on the stomach. They contain substances like chitin, mannitol, and trehalose, which are difficult for the intestines to digest. Some people may lack the enzyme needed to break down trehalose, leading to digestive problems like flatulence and diarrhoea. Mushrooms are also known to cause gas and bloating, which can further irritate an upset stomach. However, cooked mushrooms are generally considered safe to eat in moderation, provided they are not wild mushrooms, which can be poisonous.
