Mushrooms are a nutritious food, packed with vitamins, minerals, antioxidants, and fiber. While they can be eaten raw, cooking them is generally recommended. This is because mushrooms have a tough cell structure made of chitin, which is hard for humans to digest. Cooking mushrooms breaks down this structure, making them easier to digest and releasing their nutritional and medicinal compounds. Cooking also reduces the risk of bacterial contamination and destroys any toxins and carcinogens, such as agaritine, which is found in button mushrooms. However, some mushrooms, such as button mushrooms, white mushrooms, cremini, portabellas, and enoki mushrooms, can be safely consumed raw and are often used in salads or with dips.

What You'll Learn
Mushrooms are nutritious, but cooking improves bioavailability
Mushrooms are nutritious and can be enjoyed in a variety of dishes, from salads to cooked meals. While they can be eaten raw, cooking them improves their bioavailability, making their nutrients more accessible to the human body.
The cell walls of mushrooms are made of chitin, a tough substance also found in the shells of crabs and lobsters. Chitin is a complex carbohydrate that is challenging for humans to digest. Cooking mushrooms helps break down these cell walls, making them easier to digest and releasing nutritional and medicinal compounds that can then be absorbed and utilized by the body.
Mushrooms are a good source of selenium, vitamin D, vitamin B6, and B vitamins like riboflavin and niacin. Cooking increases the bioavailability of these nutrients, allowing the body to absorb and use them more effectively. For example, the cooking process increases the levels of polyphenols and antioxidants, including carotenoids and ferulic acid.
Additionally, cooking mushrooms can reduce the risk of ingesting parasites, bacteria, and viruses. Certain varieties, such as morels and shiitake, must be cooked to avoid unwanted effects like food poisoning and skin rashes. Cooking also enhances the flavour and texture of mushrooms, making them a more appealing and versatile ingredient in various dishes.
While some mushrooms can be eaten raw, such as button, white, cremini, portabella, and enoki mushrooms, cooking is generally recommended to improve their nutritional value, enhance their flavour, and ensure safe consumption by reducing potential toxins and contaminants.

Raw mushrooms can be contaminated with bacteria
Mushrooms are highly nutritious and are considered a superfood. They are rich in selenium, vitamin D, vitamin B6, riboflavin, and niacin. While raw mushrooms can be nutritious, they can also be contaminated with bacteria. The human body is the greatest source of contamination in mushroom cultivation. Human hands and clothes can carry bacteria and spores that can ruin crops. Bacterial contamination can also be caused by contaminated water, substrate, or equipment.
Bacteria thrive in damp conditions, and incorrect sterilization can lead to bacterial growth. The most common type of bacterial contamination in mushroom cultivation is Bacillus spp., also known as "wet spot" or "sour rot." This contamination is commonly found at the bottom of grain jars and monotubs and is characterized by a sour smell and slimy gray appearance. Dormant Bacillus endospores are heat resistant and can survive sterilization, but they can be killed by soaking the grains for 12 to 24 hours before sterilization.
Other types of bacteria that can contaminate mushrooms include Pseudomonas and Listeria. Pseudomonas bacteria are naturally present and usually harmless, but excessive water on the mushroom's surface can increase their growth. Listeria is a type of bacteria that can be harmful to pregnant individuals, who may prefer to consume cooked mushrooms to reduce the risk of contamination.
To prevent bacterial contamination, it is important to use sterilized substrates and clean, sterile work surfaces and tools. Soaking grains or substrates before sterilization can help kill heat-resistant endospores. Additionally, providing adequate air exchange can help prevent water droplets from remaining on mushrooms, reducing the growth of Pseudomonas bacteria.
While raw mushrooms can be contaminated with bacteria, proper cultivation, handling, and storage practices can help reduce the risk of contamination and make mushrooms safer for consumption.

Cooking breaks down chitin, aiding digestion
Mushrooms are highly nutritious and considered a superfood. They are high in selenium, vitamin D, and vitamin B6. However, they have a very tough cell wall made of chitin, a complex carbohydrate similar to cellulose, which is quite hard for humans to digest. Cooking mushrooms helps break down this wall, making them more accessible to the body and easier to digest.
Chitin is a common type of fiber found in fungi, insects, and crustaceans. It was once thought to be indigestible by humans, but recent research has shown that humans produce an enzyme called acidic mammalian chitinase (AMCase) that can break down chitin in the stomach under acidic conditions through a process called hydrolysis. Hydrolysis uses water to break the bonds between the long chains of N-acetylglucosamine that form chitin's rigid structure. Cooking mushrooms breaks down their chitin content, making them softer and easier to chew, and potentially increasing the availability of certain nutrients.
The benefits of cooking mushrooms extend beyond improving their texture and digestibility. Cooking can also reduce the risk of bacterial contamination, making mushrooms safer to consume. This is especially important for wild-foraged or improperly stored mushrooms, which may carry harmful bacteria. Cooking mushrooms can also enhance their flavor through the Maillard reaction, a chemical process between amino acids and reducing sugars that produces new flavor compounds.
While cooking mushrooms has several advantages, it is important to note that raw mushrooms can be part of a healthy diet as well. Certain types of mushrooms, such as Button mushrooms, are commonly eaten raw in salads. However, it is always recommended to follow food safety guidelines and thoroughly wash mushrooms to eliminate any soil or residue that may contain harmful bacteria or pesticides.
In summary, cooking mushrooms breaks down their chitin content, making them softer, easier to digest, and potentially enhancing the availability of certain nutrients. Additionally, cooking can improve flavor, reduce the risk of bacterial contamination, and enhance food safety. However, raw mushrooms can also be safely consumed and offer nutritional benefits when properly sourced and prepared.

Some mushrooms are toxic when raw
Mushrooms are highly nutritious and are considered a superfood. They are high in selenium, vitamin D, and vitamin B6. While some mushrooms can be eaten raw, such as Button, Oyster, and Shiitake mushrooms, some mushrooms are toxic when consumed raw.
Honey mushrooms, for example, require thorough cooking to break down their mild toxins and eliminate harmful bacteria. False morels, which resemble the highly toxic "Death Cap" mushroom, should also be avoided, whether cooked or raw, as they contain naturally occurring toxic compounds. Similarly, raw Chanterelle mushrooms can cause mild gastrointestinal upset in some individuals.
It is important to choose edible and palatable mushroom varieties such as common white button, cremini, and portobello mushrooms. Wild mushrooms can be highly toxic and easy to misidentify, so foraging for mushrooms without expert knowledge can be dangerous. Mushrooms obtained from farmer's markets, supermarkets, and reputable grocers are generally safe to consume raw or cooked.
Cooking mushrooms is recommended as it breaks down their tough cell walls, making them easier to digest and releasing more nutrients. Cooking also reduces the risk of ingesting parasites, bacteria, and viruses, and enhances the flavour and texture of mushrooms.
