A food allergy is caused by your immune system, which takes the proteins from harmless foods as a threat. This is due to a chain chemical reaction which triggers allergic reactions. The Immune system protects the body against any threat to your body. This is a signal which has the right release chemicals which can treat and prevent the spread of infections. One of the most common allergies is an antibody known as immunoglobin E, which triggers certain food as a threat and cause severe chemical released, causing histamine.


Histamine causes are quite similar to allergic reactions. Histamine causes the small blood vessels to expand in the surroundings, which can lead the red in the blood to swell. It affects the nerves and can also cause itchiness and can increase the amounts of mucus which produce in nose lining. Most of the time, the histamine is limited to certain parts of the body like mouth, throat and skin. The immune system in anaphylaxis goes into overdrive and can release very large amounts of histamine with a wide range of symptoms.

Other food allergies

There are many types of food allergies which is known as the non-IgE mediated food allergy, which is caused by many different cells in the immune system. These are quite harder to diagnose and needs a few medical tests to help ensure that non-IgE mediated food allergy. This is the type of reaction which is largely confined to the skin and the digestive system. These food allergies can also depend on allergic reactions, which includes things like eggs, milk, soy, wheat, peanuts, etc. Adults are most commonly known to have allergies to peanuts, tree nuts, fish, shellfish, etc. Other common allergies include celery, gluten, mustard, sesame seeds, fruits and vegetables, pine nuts, meats, etc.

People at risk

It is not exactly sure why people are at risk for immune system considering harmless proteins for a threat. Try to make sure that you have made sure that parents, brother, sisters with any allergic conditions do not eat anything without getting tested. This is the best way to elevate certain risks which can be higher when developing food allergies. Children who are exposed to atopic dermatitis are much more prone to developing food allergies than others.


The rise in food allergies

There are a number of people with food allergies which has risen sharply in the past few decades. There are real allergic conditions and many are unclear about the reasons for atopic dermatitis. One reason that the scientist state is the child’s diet which has changed over the years. Today, children are growing germ-free which means that their immune system does not have sufficient early exposure to the germs, which is important for their development.
