Food allergy: what is it and what is the best treatment to treat it

To certain people they can generate some food allergies. And this is a very common condition, which generally has to do with genetics. It means that people who suffer from food allergy, are more predisposed at the genetic level.

Currently, this problem affects adults more than anything, but it also manifests itself in children. In addition, it happens that allergies can be confused with intolerance, and it is important to know that they are two different conditions.

What is a food allergy about?

The food allergy It is a reaction by the immune system, which occurs shortly after eating a specific food. A fairly small amount of that food is more than enough to cause allergies. Some of the symptoms that occur in this condition have to do with hives, or even with inflammations.

There are people who suffer from allergies who experience much more serious symptoms, which can even be life-threatening, if they do not act as quickly as possible. It is estimated that these Food AllergyThey occur in 8% of children under 3 years of age, and 3% in adults. Although it is a condition that has no cure so far, most children outgrow the allergy as they grow up.

As already mentioned, it is quite easy to confuse cases of allergy with other reactions, such as food intolerance. Although it is a rather annoying disease, intolerance is not so serious and the immune system is not involved, this being a huge difference with respect to allergy, which must be taken into account.

What foods cause allergies?

When you have food allergy, the immune system mistakenly identifies a certain food, or some substance as harmful. As a defensive response, the immune system causes antibodies to be released. These, which are known as immunoglobulin, neutralize the substance or food, which causes the allergy.

The next time that specific food is consumed, the antibodies will take care of detecting it. Instructing the immune system to release histamine into the bloodstream, as well as other substances.

– Some proteins cause allergies in adults and are the following:

– Seafood as in the case of shrimp, crab and lobster.

– Any kind of peanuts.

– Other varieties of nuts such as walnuts.

– Fish.

– Certain proteins found in the foods mentioned below, generate food allergies in children:

– Soy

– Dairy products

– Eggs

Oral allergy

Within this disease, some vegetables, fruits, nuts, and certain spices, trigger allergic reactions. Causing the appearance of an annoying tingling in the mouth or itching. If the case is too severe, this is a reaction that turns into a sore throat, or anaphylaxis.

The proteins found in these foods cause allergic reactions, because they are very similar to those found in certain types of pollen. This being a clear example of what is known as cross reactivity.

Cooking all those foods that generate an allergy to pollen could reduce the most serious symptoms.

Physical activity-induced food allergy

There are foods that cause certain people to feel lightheaded or itchy, moments after starting some physical activity. If the allergy is very severe, it could cause hives and also anaphylaxis. Not eating food for at least two hours before doing any physical activity helps to control and prevent this problem.

Family history allergy: This is very important information that the doctor has to know, since it depends on whether the reactions are more serious or not.

Physical exploration: Tests will be done to help determine the existence of any other medical problems.

Skin tests: Skin prick tests could identify a reaction to a specific food. The test consists of placing an amount of the suspect food on the skin of the affected person. The skin will then be pricked using a needle to get the substance under the skin.

Being allergic to such food, a lump will form or a reaction will appear. Although it should be borne in mind that having a positive reaction using this test will not be sufficient to determine the existence of allergy.

Blood test: Performing blood tests are used to determine how the immune system responds to certain foods.

Elimination of foods in the diet: The doctor will probably order the elimination of some foods in the diet. A procedure like this is very helpful in relating symptoms to certain substances. Unfortunately, this is a method that doesn't always work.

Oral provocation using food: It is usually done within the doctor's office, where very small amounts of the suspect food are administered. Causing allergy-related symptoms, which should increase in no time. When you do not have a reaction through a test like this, the food can be incorporated into the diet without problems.

Carry the injector at all times. It may be an excellent idea to take the injector anywhere, or to have an additional one in the most frequented places.

Replace epinephrine before expiration. Otherwise, the injector will not work properly.
