Not all bodies react to the same products, chemicals, and foods in the same way. For example, some metabolize food very efficiently, while others are not as efficient or even unable to metabolize it. In some people, certain foods can even cause negative responses from the body, as is the case in people who are lactose intolerant , a well-known condition. Many other foods can cause intolerance, but among the many types of foods consumed around the world it can be difficult to distinguish which one is causing a disturbance.

To answer this problem, experts have developed a test that allows identifying intolerance to many types of food simultaneously. We invite you to continue reading this article by FastlyHealto find out about the food intolerance test: what it is for and how it is done .

What is the food intolerance test

The food intolerance test is a medical test that is recommended for people who suspect that they have some type of sensitivity to certain types of food . It is a test that has become more and more popular and that claims to be able to distinguish possible intolerance reactions from more than 200 different types of food.

Determining the foods that can cause an intolerance is important since many people tend to assume that they are allergic to some food, even when the symptoms that are manifested are not those corresponding to allergic responses. This is especially noticeable in parents with respect to their children and, in general, it means that the numbers of people who believe they are allergic can be almost ten times higher than the real numbers. This makes the food intolerance test important, in order to distinguish intolerance reactions from true allergic reactions.

How to perform the food intolerance test

The test consists of a blood test to determine the presence of sensitivity of structures that are part of our immune system, called immunoglobulins G (IgG), which are responsible for reacting to the proteins that certain foods contain, thus creating a response different from allergic, which is mediated by another type of immunoglobulin (IgE).

The results of the blood test will be given to you once obtained along with a complete list of foods to which the test has shown that you are intolerant so that in this way you avoid them, and you could even be given a suggested diet to supplement the food that you should avoid. An example would be this diet for lactose intolerance .

Food intolerance test: when to do it

In general, the food intolerance test is suggested to people who have a wide variety of recurring problems and symptoms without an apparent cause that can explain them. The people who most commonly perform it are those who suffer from endocrine problems and therefore have problems losing weight, even when they comply with their usual treatment. The food intolerance test seeks to eliminate certain foods from the diets of these people in order to achieve weight control.

Other people for whom the food intolerance test is often suggested include people with dermatological problems such as acne , hives and psoriasis , psychological problems such as anxiety and depression , and neurological problems such as migraines, constant dizziness and vertigo.

Validity of the food intolerance test

Although in recent years this test has become very popular as a remedy to improve a wide number of conditions, many experts consider it a test that must still be viewed with some skepticism, claiming mainly that the only food intolerances that can be diagnosed are to lactose and gluten .

To the above, other experts add that they should not be considered reliable tests, because there is little scientific evidence to support their results, also claiming that the results are not reproducible and that the symptoms of patients with intolerance, which is why some major medical societies advise against its implementation.
