The cause and manner of handling food allergies. Food allergy is a hypersensitivity reaction of the immune system to certain foods. Foods that commonly cause allergies are cow’s milk, cereals, nuts, egg whites, fish and shrimp. Allergies can also be caused by sulfide or salicylates in foods and medicines, food flavorings, preservatives and synthetic dyes.
In some babies, the protein can not be digested optimally due to the activity of digestive enzymes are not fully developed. In addition, they have the intestinal mucosal permeability for macromolecules larger than adults. As a result, the protein that has not been broken down more absorbed in the small intestine that cause allergic reactions.
Symptoms of allergy and severity vary in each person. Different foods can trigger the symptoms are different. Reactions to foods usually appear within an hour after eating or less. Allergies to certain foods such as cow’s milk allergy and egg allergy tend to disappear as children grow older. Allergy shrimp, fish, shellfish and nuts tend to continue until a long time.
The cause of food allergy
Our bodies are protected from infection by the immune system. We produce a type of protein called an antibody to mark the germs that cause infection. There are different types of antibodies, and that causes an allergic reaction is called immunoglobulin E (IgE). IgE antibodies are usually produced in response to parasitic infections, such as malaria. However, some people produce IgE in response to certain foods.
The first time you eat food allergens, your immune system responds by making IgE. IgE in this case acts like a molecular marker of food allergens. When you eat food again, the body will secrete IgE antibodies and other chemicals, including histamine, to expel the enemy from your body protein.
Histamine is a powerful chemical that can affect the respiratory system, gastrointestinal tract, skin, or cardiovascular system. As a result of this response, symptoms of food allergy occur. Your symptoms depend on where in the body the histamine is released. If you remove it in the ear, nose, and throat, you may feel itchy on nose and mouth, or difficulty breathing or swallowing. If histamine is released in the skin, you may develop hives or rash. If histamine is released in the digestive tract, you likely will develop stomach pain, cramping, or diarrhea.
We do not know why some foods can cause allergies and others do not, but the likelihood is that some of the protein in the food is very similar to the protein found in viruses and bacteria. Therefore, allergy usually is a genetic predisposition in which a person’s immune system is not able to distinguish protein foods with a virus or bacteria.
Handling on food allergies
After knowing the foods that cause allergies, you should avoid it. However, this can sometimes be difficult because there are hidden ingredients such as additives, peanuts, soybeans, milk protein, etc. that may not be mentioned in the product packaging. In this case, you should always buy the products from the same brand, you know do not cause allergies. In most cases, the use of antihistamines to reduce swelling and itching due to allergies.
