I can no longer eat cod roe because of lipstick…an unexpected factor! Adult Food Allergy” is at the Forefront of the case studies.

Jogging causes “wheat flour allergy.

In some cases, the symptoms do not appear until certain triggers are added to the food. A typical example is “exercise. It is called “food-dependent exercise-induced anaphylaxis,” and it occurs only when exercise is performed within 2 to 4 hours after ingestion of the causative food.

‘ Besides exercise, secondary factors include antipyretic analgesics, excessive fatigue, stress, and alcohol consumption.”

It is only recently that factors other than food have become apparent!

Allergies are a real nuisance. It would be easier to understand if you think of it like a cough, for example. There are many causes of coughing, and it’s not just one disease. Adult food allergies are just like that.”

Oral sensitization,” in which people gradually become allergic to food as they eat it, has been well known for a long time, but “extraintestinal sensitization” has become increasingly clear over the past 10 years.

For us allergists, the “Cha no Shizuku Soap” incident in 2011 had a strong impact. We were like, ‘How can something so unexpected cause a food allergy? ‘” he said. Since then, we have been seriously inquiring whether there are causes other than food.

As for cross-reactions, there were quite a few papers from the ’90s that people become allergic to fruits due to hay fever. ……

Incidentally, the “old Cha no Shizuku soap problem” was an incident in which people who used soap containing ingredients hydrolyzed from wheat developed systemic allergies when they ate wheat-containing foods and then exercised. The manufacturer and distributor are still voluntarily recalling the product.

The most frightening thing now is the “that thing” that the government is trying to recommend.

Adult allergies are complicated and bizarre. New allergies are likely to appear in the future due to changes in our living environment. In such a situation, Dr. Fukutomi is now most concerned about …….

He says, “It is allergy caused by eating insects. The government is trying to promote it, but I think there will be a lot of patients. People who are allergic to crustaceans have a high rate of symptoms when they eat insects, and if they continue to eat them, they will gradually become allergic to them. The papers show that there are ethnic groups with high insect diets. In Laos, for example, there are reports of high levels of insect allergies.”

Some airlines offer in-flight meals with edible crickets, but are they safe?

No, I think it is dangerous. The symptoms are similar to those of a shell allergy, and those with severe allergies can suffer from severe anaphylaxis.

No pollen, no pets, no insects. …… I can’t even exercise. I’m getting kind of scared. What on earth should I eat?

‘I’m not… I’m of the position that it’s better not to think about anything before the onset of the disease. There is no point in worrying about it, and it is difficult to predict the onset of the disease by blood tests.

It is difficult to predict the onset of the disease through blood tests and other means. If you suspect symptoms, it is important to see an experienced doctor. It is important to see a doctor. Administratively, there is the Basic Law on Allergic Disease Control, and each prefecture has established a base facility for allergic disease control.

Food allergies can be life-threatening. If two or more symptoms of illness appear, such as urticaria and abdominal pain, do not hesitate to seek emergency medical attention!

Oh, by the way, doctor, was my mango allergy really “extraintestinal sensitization” after all?

No, it may not be an allergy. It is well known that yams and mangoes contain “pseudoallergens,” substances that cause prickling and irritation. Some people have quite severe symptoms of these prickly substances. So it’s hard to tell which is which just by listening to the symptoms.

See ……. You think it might just be a hypersensitivity to prickly substances?　Fearful food allergy. It’s usually too mysterious. ……
