Food allergies are abnormal reaction of the body to food. It is triggered by the body’s immune system and is quite common. Here is some information about food allergies.

Causes of Food Allergies

Food allergy occurs because the body is too sensitive to the quality of the food, so it produces antibodies to neutralize and resist foreign substances. During the process, histamine (Histamine) and other substances will be released, leading to allergic reactions. However, this process of identifying substances that the body does not need varies from person to person, and different people are allergic to different foods, which is also a common cause of food-induced diseases.

Many people mistakenly believe that only rare foods can cause allergies, but in fact, common foods can also be allergens. Proteins in milk, eggs, peanuts, sesame seeds, soybeans, wheat, nuts, seafood, etc. are most often linked to food allergies. In addition, pigments, preservatives, and additives in finished products may also become allergic causes. Food allergies can be mild and short-lived, but they can also develop serious medical symptoms, even threatening.

Food-induced adverse reactions in the body, including deficiencies in the coordination of the antibody immunoglobulin E. Immunoglobulin E will appear during eating or soon after eating food allergens. If immunoglobulin E does not play a mediating role, an allergic reaction will occur within one hour after exposure to food allergens.

Food Allergies Symptoms

Symptoms of a food allergy may include more than one of the following:

Skin rash with itching.

1. 1. Itchy nose and eyes.
   2. Sneezing and runny nose.
   3. Itching and swelling around the lips and mouth, especially where there is direct contact with food.
   4. Nausea.
   5. Pain caused by spasms.
   6. Vomiting and diarrhea.

Anaphylaxis

Anaphylactic shock is the most serious manifestation of food allergy and can be fatal. Anaphylactic shock risk factors include patients with Asthma, especially patients with poorly controlled asthma. Failure to notice the early symptoms of anaphylactic shock can be dangerous, as treating an emergency food allergy too late or without medication can have serious consequences.

If your body has these symptoms, please stop eating any food that you suspect to be allergic to, and more importantly, you should consider using antihistamine (Antihistamine). With or without serious reactions, you should seek medical assistance to determine the cause and treatment.

Some factors that increase the risk of food allergy:

1. 1. Congenital inheritance
   2. Age: Food allergies are more common in children
   3. Asthma

To prevent and reduce the risk of food allergies, knowledge of food allergies and food allergy symptoms is required, as well as avoiding foods that cause allergies, skin contact or inhalation of these foods. It is recommended to memorize the clinical symptoms of common food allergies on the skin, digestive system, and respiratory system. When food allergies are severe, please go to a medical institution immediately for diagnosis and timely treatment.
