Food intolerance test. Latent food intolerance test Food allergy and food intolerance testing

A negative response of the body to the use of any food or drink associated with problems with their digestion.

Most patients are not well informed about food intolerance, which is even a O more dangerous than allergies. Often there is intolerance to milk and dairy products; cereals (wheat, rye, barley); peas, mushrooms, strawberries, etc. According to the latest data, many people have intolerance to any products, but they are not aware of its existence, because the reaction appears only after a few days.

If the general condition worsens after consuming any product, this is not a direct indication of an allergic reaction or poisoning. It could be due to a food intolerance.

Often patients mistakenly attribute food intolerance to, but these are different conditions. Allergy is manifested by characteristic symptoms (rash, swelling, reactions from the gastrointestinal tract, respiratory system), manifestations of food intolerance are more diverse (pustules on the skin, fullness, weakness, even urolithiasis, fatigue is possible). In some cases, food intolerance is asymptomatic. The only sign is poor health. Therefore, identifying food intolerance can be quite difficult.

Diagnosis (food intolerance test)

To diagnose food allergies, the ENZYME IMMUNE DETERMINATION METHOD is used - a blood test for antigens of products that enter into an immune reaction. As a result, lists of allowed and prohibited products are compiled for the patient. After the final diagnosis, allowed foods should be the basis of the diet. Products from the prohibited list, on the recommendation of a doctor, must be excluded for a period of 6 weeks to 6 months (the duration depends on the strength of the reaction, which shows the level of immunoglobulin G). After some period of time, intolerance to certain products can pass - this is the main difference between intolerance and allergy.

If, as a result of the exclusion of products from the “black list”, there is an improvement in well-being, the condition of nails and hair, skin, weight loss, normalization of bowel function, the test was performed correctly. A follow-up food intolerance test is performed six months later to identify foods that will permanently remain on the banned list.

The test allows you to check from 20 to 300 products, the amount is determined based on the patient's daily diet.

Food intolerance testing requires prior preparation. It is forbidden to eat 5 hours before the event, not to drink alcohol and some medications during the day, for example, antihistamines, hormonal and antibacterial. To clarify personal recommendations, you must first consult with a specialist.

Why EMS?

• All EMC dermatologists-allergists have significant experience in diagnosing and correcting food intolerances in both adults and children.
• All diagnostic possibilities are collected in one building. Diagnosis is carried out quickly, at any time convenient for the patient. The results are prepared as soon as possible.
• The capabilities of the multidisciplinary medical center allow treating any concomitant pathologies together with therapists, gastroenterologists, endocrinologists, cosmetologists and other specialists.

Complications of food intolerance

When a patient constantly eats foods that the body cannot absorb, inflammatory processes begin to develop. Over time, they become chronic, arthritis, migraine, eczema, irritable bowel syndrome and chronic fatigue, depression, acne, constipation, and other diseases appear. The load on the kidneys increases, which causes disturbances in the removal of fluid from the body. As a result, the patient begins to gain weight. The number of foods that are not absorbed by the body increases over time, the body may not digest well even those foods with which there were no problems before. As a result, after almost every meal, the patient becomes ill. Therefore, weight loss without compromising health can be achieved by excluding "intolerable" foods.

Symptoms of food intolerance

Symptoms of food intolerance can be very diverse in their manifestations, but none of them can be considered specific to this pathology. Symptoms may also be subtle and manifest as malfunctions in the digestive system. Regardless of the situation, only a doctor can correctly diagnose the condition.

Some of the manifestations of food intolerance

bowel problems(bloating, constipation, diarrhea). Digestive disorders are direct evidence that the body does not tolerate any products.

Heartburn. Irritation of the mucous membrane of the esophagus appears due to the inability of the body to properly absorb problem foods.

Uncontrolled appetite. The expression “everything is good in moderation” does not apply to foods that cause food intolerance. For most people, one sip of milk is enough to start producing antibodies that create a characteristic immune response. The body produces more of them than it needs, which is the cause of uncontrolled appetite.

Headache. Headaches can occur due to the body's inability to digest foods containing gluten, lactose, or sugar.

Fatigue. Fatigue is caused by inflammatory processes that are associated with the use of problem foods.

Joint pain. Joint pain can be associated with intolerance to dairy products, soy and gluten, and are the result of inflammatory processes in the body.

Acne, rashes and other skin problems. Rash, eczema, itching, red spots or dark circles under the eyes can also be an immune response to problematic foods.

Other possible symptoms: skin itching, swelling of mucous membranes, lowering blood pressure, nausea, vomiting, discomfort in the mouth.

Some interesting medical facts:

Every 4th person does not tolerate milk.

Every 250th cannot eat rye, wheat, barley and products that contain them.

Often people do not tolerate nuts and mushrooms, as well as soy and corn.

Food intolerance is an atypical response of the body to the consumption of certain foods. In contrast, it is not associated with the formation of specific antibodies to the “irritant food”. Common causes are a lack of certain enzymes, a non-allergic release of inflammatory mediators (pseudo-allergy).

The purpose of the study is to determine the amount of Ig G4 developed for specific types of products.

IgG4- a specific protein compound that is formed in response to the introduction of foreign particles (antigens) into the body. Some experts believe that the higher the concentration of Ig G4 to a particular product, the greater the likelihood of food intolerance. This information, as well as the effectiveness of the technique itself, is still the subject of debate.

For the study, blood serum and a set of food antigens of interest are used. An intolerance test can be performed on several types of food at once. A set of antigens is combined into a food panel. Panels differ depending on the list and quantity of products. The number of antigens in a panel often reaches several tens.

After the study, the patient receives a table with a list of products, the concentration of Ig G4 for each of them (in ng / ml) and the norms for comparison. Depending on the indicators, the doctor forms recommendations for correcting eating behavior.

Methods for detecting food intolerance

The search for etiology is carried out individually. It begins with the conduct and examination by specialists (immunologist, allergist, gastroenterologist). After comparing the primary data, excluding true allergies, resort to additional methods. Some examples:

Determination of Ig G4 to the panel of products, including milk, in such a situation will be uninformative. Food intolerance is a condition that can develop through several fundamentally different mechanisms. For this reason, there is no universal method for confirming it, and it is not worth spending money on determining Ig G4 without a doctor's recommendation.

Basic preparation measures:

There are practically no contraindications. The study is carried out in vitro (“in vitro”), therefore it is safe for the body.

What are the most common food intolerances?

Allergies and intolerances are not mutually exclusive. Both states can be recorded in response to the same meal. Foods that are often found intolerant:

When is it necessary to undergo an examination?

Under the guise of food intolerance, other diseases can hide. In order not to be mistaken with the research method, it is better to consult with your doctor first. Symptoms that warrant a visit to the doctor.

This is a simple and effective way to improve the body, reduce body weight, fight various somatic diseases.

Food intolerance test- a technique developed and widely used throughout the world, adapted to the products used in Russia.

Food intolerance test- this is a strictly individual diet based on the reaction of cells and structures of your body.

Poor nutrition is one of the main reasons that reduce a healthy full life. Improper nutrition worsens the course of chronic diseases, and rational, on the contrary, helps to maintain the necessary balance in the body, preventing the development of the disease.

If there is a clear allergic reaction to certain foods (skin manifestations, swelling, itching, etc.), we simply exclude them from the diet. But the most dangerous are those products that do not give such vivid manifestations, nevertheless cause serious harm to health, resulting in a number of diseases, ailments, and, as a result, premature aging of the body. Such latent reaction is called food intolerance.

FOOD INTOLERANCE: WHAT IS IT

The concept of "food intolerance" is broader than the concept of "food allergy", it includes both immunological disorders and intolerance of non-allergic origin. Poor food tolerance can be not only due to food or nutritional allergies, but also due to diseases of the digestive tract, enzymopathies, psychogenic and taste factors:

• pseudo-allergic food intolerance Associated with certain properties of certain foods - for example, eating strawberries, raw cabbage, radishes or fish can cause damage to the mucous membrane of the gastrointestinal tract in some patients, which leads to mechanical damage to "mast" cells and the release of histamine;
• food intolerance as a result of a deficiency of digestive enzymes.
  For example, milk intolerance due to congenital or acquired deficiency of lactase - an enzyme necessary for the breakdown of lactose - milk sugar;
• psychogenic food intolerance,
  occurs quite often, occurs as a result of stress and other changes in the mental sphere;
• true food allergy,
  associated with immunological mechanisms.

Food intolerances that are not related to allergies are common. It can be observed in the absence of enzymes that digest certain nutrients. A simple example is bloating and discomfort after eating peas and lentils. The thing is that in our intestines there is no enzyme that decomposes the carbohydrate contained in these products - stachyose tetrasaccharide; in the colon, microbes deal with it, forming a lot of gases. Some people do not tolerate mushrooms: they do not have an enzyme in their intestines that breaks down carbohydrate - trehalose; the consequences of this are much more unpleasant than after peas.

Food allergy is one of the causes of many acute and chronic diseases, therefore, the number of diagnostic tests associated with the detection of an immune response to food allergens has recently increased.

DISEASES IN THE DEVELOPMENT OF WHICH FOOD INTOLERANCE IS OF GREAT IMPORTANCE

SOLUTION -FOOD INTOLERANCE TEST

Clinical trials have shown that in 80% of cases there is a stable improvement in the condition when following the recommendations of the results of the food intolerance test. Many patients suffering from an unexplained pathology for a long time, often with pain (headaches, arthritis, etc.), when determining the source of delayed-type food incompatibility and excluding it from the diet for a certain time, in combination with a 4-day rotation diet, can get a significant therapeutic effect. , and in some cases completely get rid of their illness.

This program includes 2 stages:

1. Purification and detoxification of the body. The meaning of this stage is to exclude from the diet foods that cause food intolerance. The duration of the stage is about 3 months. At this time, purification takes place. An important point at this stage of the program is the normalization of intestinal activity, which is facilitated by the introduction of a sufficient amount of vegetable fiber into the diet and the use of liquids in the form of natural juices and mineral water.
2. Rehabilitation. At this stage of the program, you should gradually introduce into your diet the previously eliminated foods, 1 product every 3-4 days. In the absence of a negative reaction, these products can be consumed in the future no more than 1-2 times a week.

WEIGHT LOSS

For overweight individuals, eating a program based on the result of a food intolerance test leads to weight loss and stabilization. Many patients report weight loss and overall increased vitality. Recent studies on the problem of excess weight have shown that one of the main causes of obesity is the nutritional incompatibility of your body with certain foods. This serves as a trigger for the occurrence of a latent allergic reaction, which is manifested by weight gain and many other negative consequences.

Thus, it is safe to say that obesity is an allergic reaction to food. Exclusion of negative food products from the diet will not affect your well-being, energy needs, since your diet will have a sufficient list of products. Studies show that patients on a diet that eliminated allergenic foods lost weight without restricting their appetite, while improving their well-being.

BENEFITS OF A FOOD INTOLERANCE TEST:

• It is easy to use in the daily diet, because. The permitted range of products used is quite extensive.
• Safe for prolonged use.
• Easy to carry, because does not fundamentally change your lifestyle.
• Forms a certain stereotype of nutrition and internal organization, which has a positive effect on performance and quality of life.

If you suffer from concomitant somatic pathology, you can be consulted by highly qualified specialists and undergo any laboratory diagnostics at the Union Clinic Medical Center. The combination of a food intolerance test with corrective therapy for comorbidity gives an excellent effect and long-term remission.

The Food Intolerance Test is perfect for the whole family and helps you support each other in your quest for detox and health.
A food intolerance test is the key to health!

The term "food intolerance" appeared in the medical industry relatively recently: it means individual hypersensitivity to certain types of foods. But if, for example, a food allergy finds real confirmation in the form of clearly established symptoms and markers, then intolerance cannot boast of such an evidence base.

In the price lists of private medical laboratories, you can find various options for hematological tests, which, as their developers assure, easily identify food products that are dangerous for a particular person. However, why is the vast majority of them not recognized as official medicine and even simply not registered? To clarify the question of which blood test for food intolerance is more reliable, this article will help.

Characteristics of popular types of blood diagnostics

The most common three types of studies are FED, hemocode and ELISA. Since their cost often exceeds 11,000–16,000 rubles, the choice of the most reliable method should be approached with the utmost responsibility. In the worst case, it will be a shame to lose a considerable amount of money paid for an uninformative blood test.

FED

It is believed that screening of this type of venous blood contributes to the normalization of almost all body processes and gradual weight loss, which does not provoke an imbalance. The biomaterial obtained as a result of laboratory blood sampling is studied for susceptibility to an extensive list of products. At the end of the diagnostic work, food products are distributed into 4 colored columns of the final form, depending on their safety for human health:

• Green color - a beneficial effect on the body. Unlimited consumption is allowed.
• Yellow color - influence, both positive and negative, is excluded. Food is not prohibited.
• Orange is a minor immune response. The number of products should be reduced.
• Red color is an extremely negative reaction, rejection. Food intake must be reduced to zero.

Along with the result, patients are given reminders and recommendations that can help overcome problems with being overweight.

Hemocode

This diagnosis is also based on the delivery of biomaterial from a vein. The concentrated components of each product (extracts) are lowered into a test tube with a liquid, and a result is formed based on the resulting reactions. Only he, in turn, consists of lists of only 2 shades - red and green.

A chemiluminometer is a laboratory device used in the analysis of blood for hemocode

ELISA

ELISA allows you to detect the concentration of immunoglobulin IgG in blood cells. These antibodies, according to one of the voiced versions, attack food lumps that are indigestible against the background of intolerance, which are unable to give their useful components to the body. In the normal state, IgG destroys disease-causing agents.

In order to determine the reaction of an immunoglobulin to selected products, it is not at all necessary to memorize its numerical designations. Useful, dubious and dangerous types of food will be placed in the tables in green, yellow and red, respectively.

Food intolerance has not yet been characterized by a clear symptomatology, by which it would be possible to determine its presence. Separate signs indicate thousands of diseases, therefore, a relative indication is considered to be the presence of a complex of physiological abnormalities in a person.

The most commonly reported pathological manifestations include:

• flatulence of the intestine;
• chronic heartburn;
• constipation;
• drowsiness;
• general weakness;
• swelling of the eyelids;
• anorexia;
• obesity;
• muscle and joint pain;
• dyspnea;
• unexplained increase in BMI;
• tachycardia;
• apathy;
• dizziness immediately after eating.
• puffiness;
• diarrhea;
• cellulite.

Special indications include various forms of inflammation - cholecystitis, gastritis, sinusitis, glomerulonephritis, colitis, pancreatitis, enteritis, otitis, etc. It is also recommended to donate blood for food intolerance to those who suffer from diseases of the gastrointestinal tract, mainly gastric ulcers, hypolactasia ( lactose intolerance), dysbacteriosis or erosion.

Skin rashes (acne, papules, pustules) are often the result of malnutrition

Screening

All 3 types of diagnosis require venous blood from the cubital vessel. The procedure is carried out in the following order:

1. The person sits down on a couch or chair.
2. The laboratory assistant chooses a hand more suitable for analysis and fixes the tourniquet on the lower part of the shoulder. If the vessel is not visible well enough, the patient will have to work a little with his fist.
3. The site of the future puncture is disinfected with medical alcohol.
4. The needle of a syringe or vacuum system is inserted into the vein at a slight angle. Through it, the required amount of blood is taken.
5. A sterile swab is pressed against the wound while the needle is withdrawn from the vein. The harness is removed.

It is necessary to hold the gauze disk over the puncture until the bleeding stops completely. Detailed results will have to wait from 7 to 10 days.

What does the preparation include?

Such a substance as blood requires a reverent attitude towards itself, since the wrong approach to the daily routine and diet can seriously affect its composition. To avoid a false result, you should introduce several rules into your life 3-7 days before the diagnosis. Stop drinking all drinks containing alcohol and caffeine. Replace fast food and semi-finished products with fresh fruits, vegetables, berries, as well as simple dishes prepared by one's own hands.

Monitor the psychological state, stopping bouts of nervous overstrain, panic and stress. Minimize the amount of sweets and flour products. Do not carry over high-calorie meals for the evening. Exclude such a method of heat treatment of dishes as frying in favor of baking and steaming. Avoid heavy physical exertion on the musculoskeletal system.

Venous blood is taken on an empty stomach, so the last meal should be taken 8-12 hours before the procedure.

Before a blood test, it is not allowed to smoke and actively move. If on the day of the planned trip to the clinic a person has symptoms of acute respiratory diseases (nasal congestion, tearing, weakness, fever), then the blood collection procedure should be postponed until complete recovery.

Reliability of analysis

Not a single hematological study associated with the detection of food intolerance has been accepted by official medicine. The extreme ambiguity of such procedures is regularly reminded by scientists from Russia, the USA, Australia, Japan and the UK. Even the very principle of identifying a ghostly pathology, which has not yet been assigned the status of a disease, is questioned.

As noted earlier, IgG antibodies are indeed produced in greater volumes when certain foods are ingested. But it turned out that this is a normal phenomenon caused by the regular consumption of the same food. And given the widespread chemicalization of the food industry, it is not surprising that the body rejects food consisting of a complex of dyes, flavors and preservatives. In most cases, the cause of intolerance is not food at all, but dangerous additives in them.

A mandatory point of preparation is a discussion with a specialist on the further use of drugs (at least 8–10 days before screening)

That is, we are not talking about deviations, on which, in fact, the derivation of the results of ELISA (enzymatic immunoassay) is based. The technique of conducting the hemocode also raises a number of questions. For example, if a blood test involves isolating extracts from a variety of foods, why are they all formed in the same solvent? Such an omission reduces the information content of diagnostics to zero.

Neither hematologists nor immunologists can explain the algorithm for detecting food intolerance through the use of expensive blood tests. Moreover, even the developers themselves do not give a clear explanation on this matter. Some experts believe that such tests are a form of profitable fraud.

On the one hand, patients can think about their health, having received unsatisfactory test results, and subsequently lead a healthy lifestyle. But on the other hand, if the principle of conducting the procedures is still unknown, who will guarantee that the study indicators will not be falsified. After all, then a gullible person can throw all his strength into solving the identified "problem", while the real disease, which was indicated by vague symptoms, will continue to progress.

There were known cases when allergen products were highlighted in the red list of final forms. But an allergic reaction, as mentioned earlier, has nothing to do with the new term - its existence has been proven for a long time, and it is diagnosed using much more reliable research methods.

Classical blood tests, such as CBC, take into account many factors that affect the change in markers. And tests for food intolerance often do not take into account either the patient's history or age category. Another aspect is the set of symptoms. Any recognized disease is characterized by a set of ailments, thanks to which people distinguish one pathology from another. But how then to describe food intolerance?

If you look closely, you can see that the list of indications for a blood test includes physiological ailments that are observed in most people. For example, drowsiness and dizziness - many schoolchildren, students, workers, and also pensioners suffer from these symptoms alone. Very convenient signs for making profit from the maximum number of people.
