Question 1

Q: Can humans digest raw mushrooms?

Accepted Answer

A: Humans can digest raw mushrooms, but not very well. Raw mushrooms contain chitin, a tough material that makes up their cell walls. Humans have some enzymes called chitinases that can break down chitin, but they are more effective against parasites than food sources. Raw mushrooms will only provide some fiber to the diet, but not much of the other nutrients.

Question 2

Q: Can you eat mushrooms raw?

Accepted Answer

A: You can eat mushrooms raw, but it depends on the type of mushroom. Some mushrooms are poisonous or have harmful substances that can cause nausea, vomiting, or even death. You should always identify the mushroom before eating it and avoid eating wild mushrooms unless you are an expert. Even edible mushrooms may have bacteria or dirt on them, so you should wash them thoroughly before eating.

Question 3

Q: What are the benefits of cooking mushrooms?

Accepted Answer

A: Cooking mushrooms helps break down their cell walls and release their valuable compounds. These compounds include antioxidants, vitamins, minerals, and even some substances that can boost your immune system and fight cancer. Cooking also kills any harmful bacteria or toxins that may be present in the mushrooms. Cooking methods such as sautéing, grilling, or roasting can enhance the flavor and texture of the mushrooms as well.

Question 4

Q: Are mushrooms healthier raw or cooked?

Accepted Answer

A: Mushrooms are healthier when cooked because cooking increases their antioxidant levels and activity.

Question 8

Q: How should I cook mushrooms to get the most benefits?

Accepted Answer

A: According to a study by Choi et al., 2006, edible mushrooms should be heated to at least 140 ˚F for 3 to 4 hours, or better yet, over 180 ˚F, or best of all, above 200 ˚F. This will increase their antioxidant levels and activity, as well as make them tender and safe. You can cook mushrooms by sautéing, grilling, roasting, boiling, or baking them. You can also add spices, herbs, or sauces to enhance their taste.

Question 9

Q: What are white button, cremini, and portobello mushrooms?

Accepted Answer

A: White button, cremini, and portobello mushrooms are all the same mushroom species, Agaricus bisporus. They are harvested at different stages of growth. White button mushrooms are the youngest and smallest, cremini mushrooms are middle-aged and brown, and portobello mushrooms are the oldest and largest.

Question 10

Q: Are white button, cremini, and portobello mushrooms safe to eat raw?

Accepted Answer

A: These mushrooms are generally safe to eat raw, but they may contain some harmful pathogens or toxins that can be eliminated by cooking. These mushrooms also contain a substance called agaritine, which is a type of phenylhydrazine that may cause mutations in DNA and increase the risk of cancer. However, the amount of agaritine in these mushrooms is low and not very mutagenic.

Question 11

Q: What is agaritine and why is it important?

Accepted Answer

A: Agaritine is a substance that is found in some mushrooms, especially in the button mushroom species Agaricus bisporus. Agaritine is a type of phenylhydrazine that may cause mutations in DNA and increase the risk of cancer.

Question 12

Q: How much agaritine is in mushrooms and how does it vary?

Accepted Answer

A: The amount of agaritine in mushrooms varies depending on several factors, such as the type of mushroom, the stage of growth, the part of the mushroom, and the source of the mushroom. Freshly harvested mushrooms from early flushes have relatively high levels of agaritine, but samples from supermarkets have less agaritine. The agaritine content is not evenly distributed in the mushrooms. The highest amounts are found in the skin of the cap and in the gills, while the lowest are found in the stem.

Question 13

Q: How does storing or cooking mushrooms affect the agaritine content?

Accepted Answer

A: Storing or cooking mushrooms can reduce the agaritine content significantly, but to different extents depending on the method. Storing the mushrooms in the refrigerator or freezer, or drying them, can reduce the agaritine content by 20-75%. Cooking the mushrooms can reduce the agaritine content by 23-50%, depending on the method. Boiling, baking, frying, deep frying, and microwaving are some of the methods that can reduce the agaritine content. However, boiling can also extract some of the agaritine into the broth, which should be discarded if you want to avoid consuming it.

Question 14

Q: What is flagellate dermatitis and what causes it?

Accepted Answer

A: Flagellate dermatitis is a rare skin reaction that can occur after eating raw or undercooked Shiitake mushrooms. It causes itchy, red, and blistered stripes on the skin, resembling whip marks. It usually appears 24 to 48 hours after eating the mushrooms and can last for days or weeks. The most common areas affected are the trunk, arms, legs, and neck, but sometimes the face or scalp can also be involved. The cause of flagellate dermatitis is a substance called lentinan, which is a type of polysaccharide found in Shiitake mushrooms. Lentinan stimulates the production of a chemical called IL-1, which causes inflammation and blood vessel dilation.

Question 15

Q: How can I prevent or treat flagellate dermatitis?

Accepted Answer

A: The best way to prevent flagellate dermatitis is to avoid eating raw or undercooked Shiitake mushrooms altogether. Even if you cook them well, you may still have a chance of developing the condition if you are sensitive to lentinan. Therefore, it is advisable to stay away from Shiitake mushrooms if you have had flagellate dermatitis before or if you have a history of allergies or asthma. If you do develop flagellate dermatitis, you can use topical creams or ointments to soothe the itching and inflammation, such as corticosteroids or antihistamines. You can also take oral antihistamines or painkillers if needed. However, you should consult your doctor if the symptoms persist or worsen.

Question 16

Q: What are morel mushrooms and false morel mushrooms?

Accepted Answer

A: Morel mushrooms are a type of edible mushrooms that have a honeycomb-like appearance and a nutty, earthy, and meaty flavor. They are prized by chefs and foragers for their taste and texture. False morel mushrooms are a type of poisonous mushrooms that look like morel mushrooms, but have a brain-like or sponge-like appearance. They are also known as Gyromitra esculenta and can cause serious health problems if eaten raw or undercooked.

Question 17

Q: What are hydrazine analogs and why are they dangerous?

Accepted Answer

A: Hydrazine analogs are substances that have a similar structure to hydrazine, a highly reactive and explosive chemical used in rocket fuel. Hydrazine analogs can damage the liver and cause cancer in animals and humans. They can also cause stomach cramps, diarrhea, and vomiting if consumed raw. Hydrazine analogs are found in some mushrooms, especially in false morel mushrooms and button mushrooms.

Question 18

Q: How can I prevent or reduce the risk of hydrazine poisoning from mushrooms?

Accepted Answer

A: The best way to prevent or reduce the risk of hydrazine poisoning from mushrooms is to avoid eating raw or undercooked false morel mushrooms at all costs. You should also cook button mushrooms well before eating them, as cooking can destroy most of the hydrazine analogs. You should also make sure that the mushrooms you eat are clean and fresh, and avoid drinking alcohol while eating them, as it may increase the toxic effects of hydrazine.

Question 19

Q: What mushrooms should you avoid eating raw?

Accepted Answer

A: You should avoid eating raw any mushroom that you don’t know what it is, as it could be poisonous or harmful. You should also avoid eating raw any mushroom that is tough, bitter, or bland, as it would not be enjoyable or nutritious. Some mushrooms that are better cooked than raw include reishi mushrooms, honey mushrooms, boletus mushrooms, and shiitake mushrooms. These mushrooms have more health benefits and flavor when cooked.

Question 20

Q: How should you prepare mushrooms before eating them raw?

Accepted Answer

A: You should prepare mushrooms before eating them raw by washing them thoroughly and checking them for any dirt, bugs, or mold.
