A food allergy is an allergy that occurs when you eat a certain food. Symptoms include body itching, hives, swelling of lips, vomiting, abdominal pain, diarrhea, coughing, and asthma. Severe symptoms are called anaphylaxis, which can be life-threatening, and include drop in blood pressure, difficulty breathing, and loss of consciousness. When teaching children with foreign roots, consider differences in customs and be sure to prevent children from coming into contact with allergens at school.
The human body has an immune system which keeps invaders like germs and viruses out of the body. Food allergies are caused by an overactive immune system responding to allergens (substances that cause allergies, mostly proteins) contained in certain foods. Food allergies are not only caused by oral intake, but can be caused by the allergen entering the body through inhalation, skin contact or injection. Symptoms from any of these cases, are called food allergies.

Symptoms that could be due to food allergies include severe and stubborn rash on the face or whole body, rash, vomiting, face turning red and difficulty breathing, and itching in the mouth after eating. If you have these symptoms, get tested for allergies at a hospital to identify the cause.

Points to Note When Working With Children With Foreign Roots
Children may come into contact with allergens other than school lunches while they are at school. There are some Japan-specific school events and classes that may include unexpected situations for children and parents with foreign roots. Talk with them about how to deal with the events and classes ahead of time.
-School events and cooking classes:
