After eating a home-cooked dish, the woman's legs were sore and numb, as if they were "whipped"! Many people love to eat it! Doctors warn →

"Red umbrella, white pole

After eating, let’s lie down together.”

This jingle always reminds people

Eating poisonous mushrooms is very dangerous

But what is unexpected is

Eating shiitake mushrooms incorrectly can be "scary"

Not long ago

Ms. Li from Hubei

I was "whipped" by mushrooms

"Whip" from Shiitake Mushrooms

Recently, Ms. Li (pseudonym), who lives in Xiangyang, Hubei, found that many red stripes suddenly appeared on both sides of her calves , as if they had been "whipped" and were extremely itchy, so she went to the hospital.

After the doctor saw her, he carefully observed the rash and asked about the course of her illness and her diet. It turned out that Aunt Li had eaten undercooked mushroom soup two days before the onset of the disease . The doctor diagnosed her with "mushroom dermatitis" based on her stripe whip erythema and clinical experience.

What is shiitake mushroom dermatitis?

Lentinus mushroom dermatitis, also known as whiplash dermatitis , is currently believed to be a mushroom toxicity reaction caused by the ingestion of "lentinan" in the cell walls of lentinus mushrooms.
Characteristics of disease

It is common in adults and rare in children. It tends to occur on the trunk and limbs , rarely on the head, face, neck, hands, and feet, and generally does not involve the skin and mucous membranes.

The disease generally has no systemic involvement, only skin damage . The typical skin lesions are characterized by whiplash-like linear or cord-like erythema, with scattered or clustered small papules and papulovesicles , accompanied by varying degrees of itching.

Why do some people get sick after eating shiitake mushrooms, which are such a common ingredient?

****The pathogenesis of shiitake mushroom dermatitis is not yet fully understood. Some scholars believe that it may be a small number of people with special constitutions who are allergic to shiitake polysaccharides in the cell walls of shiitake mushrooms.
Lentinan polysaccharides are not heat-resistant and can be inactivated by cooking at 100°C for half an hour or at 135°C-150°C. However, some susceptible people may develop a characteristic rash after eating raw or undercooked shiitake mushrooms.

In other words, shiitake mushrooms must be fully cooked before eating.

Will you only get whiplash dermatitis if you eat shiitake mushrooms?

Not only shiitake mushrooms, but some anti-tumor drugs (such as bleomycin and docetaxel) can also cause whiplash dermatitis.
In addition, oyster mushrooms, black fungus, enoki mushrooms and shiitake mushrooms all belong to the phylum Basidiomycetes and class Agaricus. Some scholars speculate that these foods may also cause whiplash dermatitis if they are not fully cooked.

Doctors say that you should avoid prolonged sun exposure after eating shiitake mushrooms, especially when the sun is strong. Because shiitake mushrooms are photosensitive, prolonged exposure to the sun after eating shiitake mushrooms may cause phototoxic reactions and lead to acute damage to the skin surface.

What should I do if I get "shiitake mushroom dermatitis"?

Which foods must be cooked before eating?

Don’t panic if you get shiitake mushroom dermatitis - shiitake mushroom dermatitis is self-limiting, and if the symptoms are mild, cold compresses can be used to relieve itching and redness;

If the symptoms are severe, such as a large area of ​​erythema, the appearance of blisters, or accompanied by systemic symptoms such as fever, you must seek medical attention promptly.

In addition to mushrooms

These foods must be cooked before eating

1. Vegetables with high oxalic acid content

Such as spinach, water spinach, celery, amaranth, purslane, etc., after oxalic acid is absorbed, it is easy to form insoluble oxalate with calcium and other substances in the body, increasing the risk of stones.

Oxalic acid is easily soluble in water, and most of it can be removed by blanching it in boiling water.

2. Poisonous vegetables

Raw green beans contain saponins, which contain hemolysins that can destroy red blood cells and irritate the gastrointestinal mucosa.

The content of colchicine in fresh daylily is relatively high. Colchicine itself is non-toxic, but after being absorbed through the gastrointestinal tract and then oxidized, it will produce toxic dicolchicine.

It is best to heat green beans at 100℃ for more than 10 minutes before eating; before eating fresh daylily, the stamens should be removed and soaked for 10-20 minutes, then blanched or cooked.

3. Raw meat and poultry

Undercooked meat and poultry may carry bacteria such as Salmonella and E. coli, as well as parasites such as Toxoplasma gondii and meat tapeworm, so meat must be thoroughly cooked before eating.

4. Eggs

Raw eggs may transmit Salmonella or Listeria, so not only should you not eat raw eggs, you are also not recommended to eat soft-boiled eggs.

Start with cold water and bring to a boil, then continue to cook for 3-5 minutes to ensure the yolk is completely set.

5. Seafood

Seafood should be cooked thoroughly. Unprocessed seafood may carry bacteria and parasites, which can easily lead to foodborne diseases after consumption.

6. Beans

They mainly include mung beans, soybeans and their soy products, which contain plant hemagglutinin. If a large amount of them enter the blood, it will cause nausea and vomiting, and in severe cases may be life-threatening.

It is recommended to boil soy milk for about 15 minutes before consumption.
