Mushrooms have been consumed and used medicinally for centuries, with some even suggesting that Ancient Egyptian pharaohs declared them royalty food. However, despite their popularity, they can be difficult to digest due to their tough cell structure and the presence of chitin, a polysaccharide that cannot be digested by the human stomach. Cooking mushrooms helps break down these structures, improving digestibility and increasing access to certain nutrients. While some mushrooms can be consumed raw, others may pose serious health risks, and children under three should not consume them due to their livers' inability to process mushroom compounds.

Cooking mushrooms improves digestion and destroys toxins
Cooking mushrooms is an important step in improving their digestion and destroying toxins. Raw mushrooms can be difficult to digest due to the presence of chitin, a polysaccharide that the human stomach cannot digest. Additionally, mushrooms contain various protein types that are poorly dissolved by stomach acids. Cooking mushrooms helps break down these hard-to-digest compounds, making them easier for our bodies to process.
Mushrooms are a nutritious food, offering dietary fiber, protein, amino acids, vitamins, and minerals. However, the cooking process can negatively impact their nutritional composition. A study by researchers from the Mushroom Technological Research Center of La Rioja in Spain found that frying and boiling mushrooms resulted in a significant loss of antioxidants, proteins, and carbohydrates. Therefore, it is recommended to grill or microwave mushrooms to preserve their nutritional properties while still making them safer and easier to digest.
Some mushrooms, such as plain white button mushrooms, contain a toxin called agaritine, which may be carcinogenic. Cooking mushrooms effectively reduces agaritine levels. For example, microwaving fresh mushroom slices for just one minute reduces agaritine content by 65%, while boiling for an hour eliminates 90% of the toxin (though it transfers to the cooking water). Frying mushrooms for 5 to 10 minutes is also an effective method to reduce agaritine levels.
It is important to note that children should not consume mushrooms due to their developing livers and digestive systems. Adults should also exercise caution when consuming mushrooms. It is recommended to limit mushroom intake to 200-300 grams per week to avoid potential exposure to environmental contaminants and to ensure adequate digestion, as mushrooms can take up to five hours to digest. Combining mushrooms with easily digestible foods, such as potatoes and lettuce, is also advisable.

Raw mushrooms may cause digestive issues
While many people enjoy eating raw mushrooms, they can cause digestive issues for some. Mushrooms have a tough cell structure, which can make certain nutrients less accessible when uncooked. The cell walls contain chitin, a polysaccharide that resembles cellulose but is not digested by the human stomach. Chitin, along with mannitol and trehalose—two carbohydrates that are difficult to digest—are strenuous for the intestines to break down. Cooking helps to break down these structures, making some nutrients more available and accessible to the body.
Mushrooms also contain a lot of protein types that are poorly dissolved by stomach acids. This means that the protein in the cells can only be absorbed if one chews well. Therefore, children who cannot chew well should avoid eating mushrooms. Moreover, mushrooms stay in the stomach for a long time—up to 5 hours—so they should not be eaten in the evening. Combining mushrooms with alcohol is also not recommended, as alcohol traps the protein of the fungus in the stomach, making it even more resistant to the effects of digestive juices, causing it to stay even longer.
Some mushrooms, such as button, shiitake, oyster, and king trumpet mushrooms, can be eaten raw but are difficult to digest in large quantities. Wild mushrooms also carry the risk of being infected by fox tapeworm. Other mushrooms, such as honey mushrooms, contain mild toxins and harmful bacteria, making them unsafe for raw consumption. Porcini mushrooms, while lacking lethal toxins, may also be challenging to digest and can cause gastrointestinal discomfort if consumed raw. True morels, while generally safe to eat when cooked thoroughly, can cause gastric upset when eaten raw.
In addition, some mushrooms contain dangerous toxins that can cause serious problems with the digestive system. These toxins can lead to nausea, vomiting, diarrhoea, and stomach pain. Poisonous mushrooms may also cause allergic reactions, hallucinogenic reactions, or even life-threatening issues like seizures, liver and kidney damage, and death. Therefore, it is generally recommended to cook mushrooms before consumption to reduce the risk of bacterial contamination and ensure they are easier to digest.

Mushrooms should not be given to young children
Mushrooms can be a delicious and nutritious addition to a meal, but it is important to know how to prepare and consume them safely, especially for young children. While most are safe to eat, some types can cause serious, even life-threatening issues, especially when raw.
When it comes to young children, there are a few reasons why mushrooms should be approached with caution and often avoided. Firstly, the livers of young children are believed to have difficulty processing and digesting certain compounds found in mushrooms. This is due to the tough cell structure of mushrooms, which contains chitin, a polysaccharide that is not easily broken down by the human stomach, especially in younger individuals. As a result, mushrooms can remain in the stomach for an extended period, causing digestive issues.
Secondly, mushrooms are not a significant source of essential vitamins and nutrients that growing children need. Therefore, including mushrooms in a child's diet may not provide them with the necessary nutritional benefits. Instead, it may fill them up and prevent them from consuming other nutrient-dense foods.
Additionally, some mushrooms contain mild toxins that can cause gastrointestinal discomfort, especially when consumed raw. While cooking can help break down these toxins, it is crucial to ensure that mushrooms are properly sourced, correctly identified, and adequately cooked to reduce the risk of bacterial contamination and potential toxicity.
Furthermore, it is important to consider the potential risks of edible mushroom products, often marketed as candies or snacks. These products are not regulated and may contain unknown ingredients or contaminants. Some of these products contain psilocybin or muscimol, naturally occurring hallucinogenic chemicals that can have unpredictable effects on individuals, including children.
In conclusion, while mushrooms can be a part of a healthy diet for adults, they should be approached with caution when it comes to young children. It is recommended to consult a pediatrician or a healthcare professional for specific advice regarding mushroom consumption for children, as individual circumstances may vary.

Avoid combining mushrooms with certain foods
Mushrooms are a great addition to any meal, but combining them with certain foods can make them harder to digest. Here are some tips to help ensure you combine mushrooms with the right foods for better digestion:
Firstly, it is important to note that mushrooms should be cooked rather than consumed raw. Cooking mushrooms breaks down their tough cell structure, making them easier to digest and allowing your body to access more of their essential vitamins and minerals. It also reduces the risk of bacterial contamination, which is higher when consuming raw mushrooms.
When cooking mushrooms, it is recommended to stew them in their own sauce rather than in creams or roux, as these can be difficult to digest. Additionally, avoid combining mushrooms with foods that are hard to digest, such as beans. Instead, pair them with easily digestible foods like potatoes and lettuce.
Mushrooms should also not be consumed with alcohol. Alcohol can trap the protein of the mushroom in the stomach, making it more resistant to digestive juices and causing it to stay in the stomach longer, which can be potentially dangerous. It is recommended to avoid consuming alcohol for at least two days before and three days after eating mushrooms.
Lastly, it is important to be mindful of the type of mushrooms you are consuming. Some mushrooms, such as those in the Boletus family, including Porcini, are better enjoyed cooked as they can cause gastrointestinal discomfort when consumed raw. Honey mushrooms, for example, require thorough cooking to eliminate harmful bacteria and mild toxins, making them unsafe for raw consumption.

Mushrooms are rich in dietary fibre, which aids digestion
Mushrooms are rich in dietary fibre, which has been linked to several health benefits. Dietary fibre is a type of bioactive compound that cannot be digested or absorbed in the small intestine. Instead, it promotes the growth of beneficial microorganisms in the gut, improving overall host health. Mushrooms are a valuable source of dietary fibre, which can be used as a prebiotic to promote the growth of beneficial microorganisms in the gut. This can lead to improved digestion and overall health.
Mushrooms contain a unique type of dietary fibre called mushroom dietary fibre (MDF), which is derived from the mycelia, fruiting bodies, or sclerotia of edible or medicinal fungi. MDF has a different structure, chemical composition, and physicochemical properties compared to dietary fibre from traditional sources such as grains, vegetables, and fruits. It is a type of carbohydrate polymer with a polymerization degree of at least 10.
The health benefits of MDF include its ability to boost the immune system, exhibit anticancer properties, and help control blood lipids and glucose levels. Additionally, MDF has been shown to improve diet-induced metabolic syndrome (MS) in mice and rats. MS is associated with dysbiosis of the gut microbiota, which can lead to metabolic endotoxemia and induce insulin resistance, obesity, and diabetes. By promoting the growth of beneficial microorganisms, MDF can help regulate the gut microbiota and improve overall health.
Cooking mushrooms can also make them easier to digest by breaking down their tough cell structure. This helps to improve digestion and make some nutrients more accessible. However, it is important to note that some mushrooms, such as honey mushrooms, should be thoroughly cooked to break down mild toxins and eliminate harmful bacteria, making them unsafe for raw consumption. Overall, mushrooms are a rich source of dietary fibre that can provide numerous health benefits, especially when properly prepared and consumed.
