string(10) "error stat"

Every person should understand that the food they eat has a direct impact on their overall health. If you feel unwell after eating a particular food, then you should get tested for food intolerance. Such a study will make it possible to understand what exactly causes negative sensations in the body, and also to avoid consuming this product in the future.

Causes of food intolerance

The food we eat can both strengthen the body and cause depression, drowsiness, acne, or various pain sensations.
Until today, scientists have not yet identified the specific causes of food intolerance. Experts cannot come to a single opinion, so we will tell you several possible reasons why food intolerance may occur:

Lack of vitamin D in the body. Almost 70% of adults suffer from this disease. Vitamin D deficiency can cause food intolerance in both adults and children.
New food. If you have not tried a product at an early age, you may experience discomfort when using it in the future. That is why doctors recommend not limiting children’s intake of exotic foods, observing the correct dosage.
Pathogenic bacteria that change the body's microflora and disrupt metabolism. As a rule, they appear after changing the diet or using antibiotics.
Psychogenic food intolerance.
Eating foods that contain large amounts of histamine. For example, egg white or red wine.
Using medications that inhibit the functioning of enzymes that destroy histamine.

Signs of food intolerance

You suffer from various diseases, your health deteriorates because attacks from “secret enemies” weaken your immune system. All the body’s energy is aimed at neutralizing the “foreign” product, which leads to a weakening of the immune system, a slowdown in metabolism, and a decrease in resistance to various infections.

Almost all of us suffer from some kind of food intolerance. The main thing is to know which food product is right for you and what your threshold of sensitivity to this product is; a blood test helps with this.

Symptoms of food intolerance are varied, often so common that a person gets used to them and considers them normal. Symptoms of poor health are always individual, since toxins released after eating the wrong food product attack various organs in the body of each person. Genetically weaker organs are subject to the greatest negative effects.

Food products that pose a health hazard. Research has proven that there are certain foods and chemicals that cause negative reactions in blood tests in most people.

These foods are:

wheat
milk
chocolate
cabbage
potato
bananas
corn
tobacco
eggs
yeast
coffee
tomatoes
strawberry
barley
veal

Foods that pose a health hazard

In the first days after stopping the use of these products, an exacerbation of various health conditions is possible. This process is similar to the withdrawal crisis that occurs when you stop drinking alcohol or smoking. Colon hydrotherapy - deep cleansing of the intestines - will help avoid unpleasant sensations.

If you've had a blood test for food sensitivities and decide to change your eating habits, you'll need to pay close attention to what ingredients are listed on the label on your food packaging. Among the other ingredients there may be one that you should not eat.

Pay attention to the milk. Your doctor has advised you to give up milk. You stopped drinking coffee with milk. However, you will be very surprised to learn that milk can “hide” in different ways and get into your plate. For example, by seasoning a macaroni dish with cheese, you, without knowing it, have consumed a prohibited product.

Milk (lactose, casein, caseinates) is found not only in cheeses, but also in most types of bread (sandwich bread, toast bread, etc.), crackers, semi-finished pasta, rice products, meat products (smoked sausage , sausages, etc.), in ice cream, pizza, cakes and various sweets, as well as in many other products.

If you can't eat eggs, don't forget that they are present in sweets, cookies, other baked goods, pasta, sauces, and ice cream. The same can be said about many other foods.

After 2–3 weeks of treatment with the nutritional system, you will feel that some health problems have disappeared. The secret of luck is that when you completely refuse a certain food product for a while, polluting products are removed from the body, and the body is detoxified. Metabolism is normalized and the immune system is strengthened.

If you give in to temptation even once, you can negate all the results achieved. When you decide to change your diet, be firm and resist the temptation to indulge yourself even with a small piece of the forbidden fruit.

Alternative foods

You should carefully and repeatedly re-read the results of the food intolerance test in order to thoroughly remember the prohibited foods and imagine the severity of a possible reaction. This will help you when choosing alternative foods and possible combinations of them.

In many cases, it is prohibited to eat foods that are often combined with each other, for example:

wheat and yeast (in bread),
wheat, yeast, sugar, eggs (in sweets and cookies).

Speaking about alternative food products, let's present a few examples:

YEAST - If your body does not accept yeast, you will have to avoid bread (natural or beer) and yeast breads, but you are not prohibited from eating baked goods made with bicarbonate of soda. You will also have to give up wine, beer and vinegar, but you can drink apple cider vinegar and unfermented alcoholic drinks.
MOLD – You can be sensitive to mold without obvious signs of sensitivity. In any case, it is recommended to refuse or limit the consumption of foods that contain a lot of sugar, honey, as well as sweet fruits (bananas, melons, etc.) and all fermented and yeast products.
WHEAT – it is prohibited to consume food products containing wheat. You can eat other cereals, for example, rice, corn, rye, barley, oats, millet, buckwheat, soy, and pea flour products.
RICE – You can make soups from barley, oats, millet or wild rice.
SUGAR BEET, BEET - It's important to remember that sugar beet extract is used to make white sugar, so depending on your intolerance you will need to use sugar cane sugar, honey or sweeteners. Beets can be replaced with other vegetables.
GRAPES are also harmful because of the yeast they contain, which is necessary for fermentation.
WINE, LIQUEURS, OTC. DRINKS - due to the dyes and preservatives used in production. Replace with fresh fruit juice and mineral water.
VINEGAR – replace with apple cider vinegar (not fermented), rice vinegar, lemon.
TEA, COFFEE, COCOA - choose other drinks that are allowed to everyone: barley coffee, decaffeinated coffee, tannin-free tea, white tea, chamomile tea, fruit juices.
VEGETABLE OIL – if olive oil is prohibited, you can use corn, soybean, peanut, sunflower oil, and grape extract. All listed varieties of vegetable oil are interchangeable. Try not to use oil mixtures or special products designed for frying. It is prohibited to eat any olives.
TUNA – can be replaced with mackerel or salmon.
CHICKEN – can be replaced with lamb, rabbit, pork, veal.
VEAL – choose lamb, goat, pork.
PORK – some dishes can be replaced with similar ones: use dried beef or horse meat, turkey or chicken sausages, turkey tenderloin.
CHICKEN EGGS - can be replaced with goose, quail, pigeon, duck and ostrich eggs.
COW'S MILK - Substitute goat milk, rice milk, soy milk, almond milk, and oat milk.
COW'S MILK CHEESE - Replace with fresh or aged sheep's or goat's milk cheeses (cottage cheese and goat's milk yoghurts are available).
GOAT'S MILK - Replace with rice, soy, almond and oat milk.
SWEETENERS – due to chemical processing, it is advisable to avoid and replace with fructose, honey.
DYES - if you are intolerant, do not drink drinks containing dyes (such as Coca-Cola, canned orange juice), do not eat ice cream, cakes containing dyes, etc.; choose light drinks, or even better, drink fresh juices.
PRESERVATIVES – if you are intolerant to preservatives, do not use products intended for long-term storage and packaged in jars.
OIL BY-PRODUCTS – The test includes the possibility of special sensitivity to petroleum by-products, such as exhaust gases, plastic food packaging, plastic bottles.
TOBACCO – You can be especially sensitive to tobacco if you are only a passive smoker.
FRUITS AND VEGETABLES – if your body is intolerant to certain fruits or greens, replace them with others.
If you have established intolerance to a large number of foods, it may be difficult to draw up a nutrition plan, so you can first give up the most unacceptable ones, gradually giving up other foods that are not suitable for you.

Food comes back to your table

For the most frightened, we repeat the comforting news: the diet does not last forever! Often the body cannot tolerate certain foods that you previously abused.

By temporarily giving up boring foods, we provide an opportunity for the complex immune system to recover, so after a certain period of time we can return them to our menu. Food products are returned to our table one at a time with an interval of 3–4 days, and are consumed at least twice in different combinations. It is recommended to follow a rotation diet when returning foods to the menu.

When reintroducing intolerable foods to the menu, you should take into account that some ailments may recur. It is important to identify them, establish their frequency and, if the ailments do not stop, give up this food product for a longer period.

If a high degree of food intolerance is established (stages 3–4), it is recommended to repeat the test after 6–8 months. A blood test can be carried out if there is the slightest case of intolerance or just to make sure that your condition is normal.

Allergy or intolerance: what's the difference?

Before you diagnose yourself with food intolerance and go to donate blood for food allergens, you should learn to distinguish it from a true allergy.

Despite the fact that these manifestations are quite similar in symptoms, they are different diseases. For this reason, the doctor, based on the overall clinical picture, can prescribe a number of necessary tests, as well as antigen testing.

Typically, food allergies are caused by seafood, peanuts, fruits, eggs, milk protein, soy and gluten.

Common allergy symptoms are gastrointestinal disorders, cutting pain in the abdomen and various skin rashes. If you are familiar with these particular ailments, then you should go to the doctor and get a blood test for food allergies.

Food intolerance occurs without interference with the immune system. All the symptoms experienced by a person with food intolerance are directly related to the digestive tract. The main symptoms are a feeling of heaviness, stomach pain and nausea.

Do you have bread with salmon and avocado for breakfast every day? Rest assured: they will be banned for you!

Change your diet, get tested in 2-3 months - and the result will be completely different. In order to understand that the menu should be varied, you don’t need to spend money. Much more useful are those organizations that do highly specialized research. For example, they study predisposition to cancer.

As for public tests, know that the American Academy of Nutrition and Dietetics 6 years ago did not recommend taking them.

The reason is insufficient evidence base. The Australian Institute of Sport also announced that this was pointless - such tests do not show predisposition to marathons or swims. So it’s better to go to endocrinologists, nutritionists, therapists and take the set of tests that will be recommended for you, based on your medical history.

Types of food intolerance

Doctors classify food intolerance into four types. Let's take a closer look at these groups.

Intolerance associated with an immunological mechanism or, in other words, food allergy. During such intolerance, the body shows incompatibility with certain foods. Therefore, you should choose your diet more carefully if you have food intolerance. Also, the list of such intolerances includes hidden allergies.
Pseudo-allergic reaction to certain foods. In this case, the body’s negative response is provoked by histamine-liberating products: cheese, ham, beer, etc.
Deficiency of digestive enzymes in the body. Violation of the gastrointestinal microflora contributes to the disruption of proper digestion of food.
Psychogenic food intolerance.

Which test is more important?

Both tests showed what I could and couldn't eat. Food is more detailed in this regard. But the genetic one gave an explanation of why and why I really need this (that this is not fashion or some kind of whim, but a completely understandable measure - all for the sake of health, preserving youth and beauty).

A DNA test has many different indicators that make it worth doing. It is especially necessary for those who are not ready to risk their beauty, but want to look good. Personally, the DNA test helped me in drawing up a cosmetology map. Now, together with the doctor, we work as a team and know what to expect from my skin and hair.

Food allergy testing: types

If you have any doubts about how your body reacts to a particular type of product, then it is worth conducting a food intolerance test. Today, a large number of medical centers provide various tests for determining food allergens.

In vitro: determination of IgG subclasses

In vitro analysis occurs by determining IgG subclasses to food allergens. This type of analysis is more recent and is based on studies that demonstrate that certain subclasses of IgG can cause different reactions. In simple terms, the clinic tests the compatibility of your IgG subclasses with certain foods, which are most often food allergens.

Prime test

Prime test is a new type of product compatibility testing for Russia. The main task of the test is to determine the individual reaction of blood cells to all kinds of food allergens (more than 150 items). After the results of the prime test, a special nutrition program is prescribed, in which inappropriate foods are excluded. In addition, testing allows you to determine the degree of intolerance to a number of products.

Hemotest

Hemotest is a technique that determines antibodies in the blood to food allergens. A genetic test is a study of your blood and its reaction to common foods, as well as the compatibility of foods with your body. In order to do a hemotest, you need to donate blood for food intolerance. This type of analysis will help to identify hidden allergies in a person, since about 130 types of food products are examined at a time.

ImmunoHealth

An analogue of the in vitro test, which is based on the determination of IgG subclasses. The main difference is that the test has a lower cost.

In general, all allergy tests are similar and test how your body interacts with certain types of foods. Testing takes place quite quickly and results can be found out the very next day. The main question about which test to choose is the prices that laboratories offer.

FED

The analysis reveals the body's response to more than 100 food products, as well as synthetic additives. Based on the test results, lists are generated in which foods are divided according to their benefits and harmfulness to humans.

Elisa

A method that is based on identifying a patient’s IgG cells for a specific product. This study is the most reliable, and the recommendation is made based on the antibodies produced.

Characteristics of popular types of blood diagnostics

Most often there are three types of studies - 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 sum 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 that 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 color columns of the final form depending on their safety for human health:

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

Along with the results, patients are given reminders and recommendations that can help overcome problems with excess weight.

Gemocode

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

A chemiluminometer is a laboratory apparatus used in blood testing for hemocode

ELISA

Enzyme immunoassay allows you to detect the concentration of IgG immunoglobulin in blood cells. These antibodies, according to one of the voiced versions, attack lumps of food that are difficult to digest due to intolerance, which do not have the opportunity to give their beneficial components to the body. Normally, IgG destroys pathogenic agents.

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

Where can I get food allergy tests done for a child or adult?

Today, a large number of private laboratories offer their services for determining food allergens. You can also do an analysis of incompatibility under the compulsory medical insurance policy in your city.

You can take a food incompatibility test both at a public clinic and at a medical center.

There are two types of food allergy tests:

Skin allergy tests. This testing exposes the patient’s skin to a large number of allergens, so the entire process occurs under the supervision of the attending physician.
Laboratory analysis. At the moment, this is the most accurate way to determine food allergies.

In order to donate blood under the compulsory medical insurance policy, you will need a passport, a medical insurance policy and a referral from your immunologist. Afterwards, you can contact any center specified in your policy and take the necessary sample.

In the case of private clinics, you can go to any institution and get tested for food intolerance.

General rules of behavior after receiving the analysis result

The results of the research are lists that indicate recommended and prohibited cereals, vegetables, types of meat, and dairy products. You can eat healthy ones without fear, try to avoid prohibited ones.

The recommendations received should be followed so that PN does not lead to serious consequences for the body. Typically, the treatment period is divided into two stages - cleansing and restoration.

During the cleansing period, the body is freed from accumulated toxins. It is useful to drink clean water, eat fruits and vegetables from the recommended list. This usually takes from 2 to 4 weeks. The doctor decides when the strict period should end. Usually at this time the condition improves, there are no signs of dyspepsia, and metabolism normalizes.

During the recovery phase, prohibited species are introduced one at a time and the reaction is monitored. The absence of disorders makes the product approved for use once every 1-2 weeks.

Recommendations are not lifetime. It is recommended to repeat the test after six months or a year.

How much does a food intolerance test cost?

Today, many laboratories provide their services for identifying food allergens. The cost depends on the type of test and the “image” of the laboratory.

In Moscow and the Moscow region, the price starts from 16,000 rubles and reaches 40,000 rubles. In regions, the price may vary significantly and be either lower or higher than the specified threshold.

In addition, you can take a free test using your compulsory medical insurance policy. To get a referral for a test, you need to contact an immunologist and describe your complaints: then the test will cost you free.

When and by whom is it appointed?

A bad reaction to certain foods leads to discomfort and increased gas formation after eating. Often this causes pain in the abdomen. Symptoms recur after eating one or more foods.

At the same time, the patient’s ability to work decreases and the quality of life deteriorates, and resistance to infectious processes weakens. In some cases, the problem leads to excess weight, as insoluble complexes are deposited in adipose tissue and swell.

Research is also carried out during pregnancy planning, for people with obesity and other chronic pathologies.

Preparing for a blood test for food intolerance

Before you go to donate blood, you need to prepare your body for the test.

Allergy skin tests

If you are planning to take a skin test, then you should know that such a test is not recommended for children under 5 years of age and adults over 60. This is due to the fact that in children the immunity has not yet been formed, and in older people it is already weakened. Since doctors cannot predict the body's reaction to antigens, the test can be dangerous.

Skin tests are less safe than blood tests, but many hospitals still use them and show good results.

The skin test is performed as follows:

The allergen is applied to the skin in the forearm area. As a rule, this is a synthetic analogue of the product.
In the place where the allergen comes into contact with the skin, a superficial incision or puncture is made;
After 20 minutes, if a reaction appears on the skin in the form of redness and itching, the product is considered an allergen.

General recommendations:

It is worth remembering that when allergies worsen, a skin test is not performed;
Also, the test is not performed during exacerbation of any chronic diseases;
The test is not performed for ARVI, flu and colds;
Testing will have to be avoided during pregnancy and breastfeeding;
Stop taking antihistamines 48 hours in advance to avoid false negative results;
If you suffer from hay fever, the analysis is carried out in autumn or winter;
The test results are valid for up to a year: then, if the need arises, the tests are repeated.

Laboratory blood test for food intolerance

At the beginning of the study, the total level of immunoglobulin in the blood is determined. After which these antibodies react with the allergen, simulating its entry into the body.

In general, all biochemical processes that occur with the participation of IgE lead to the release of histamine and other substances into the blood that provoke an allergic reaction (runny nose, suffocation, rash, bronchitis, redness) or anaphylactic shock. If a person is not prone to allergies, then the level of IgE in the blood is extremely low. In allergy sufferers it is significantly increased.

After a general blood test, the serum is combined with various allergens and tested for the presence of specific IgE.

The analysis allows you to identify most popular antigens. For example, allergies to mold, food, dust mites, animal hair, pollen from trees, grasses and other plants.

Recommendations for preparing for donating blood for allergies:

You must not eat for at least 4 hours before donating blood;
If you are taking any medications, you should also not take them 4 hours before the test;
Do not drink alcohol at least 48 hours before the test;
Stop smoking 24 hours before the test.

What does the preparation include?

A substance such as blood requires a careful attitude towards itself, since the wrong approach to 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 processed foods with fresh fruits, vegetables, berries, as well as simple dishes prepared with your own hands.

Monitor your psychological state, stopping attacks of nervous tension, panic and stress. Minimize the amount of sweets and flour products. Do not move more high-calorie meals into the evening. Eliminate heat treatment methods such as frying in favor of baking and steaming. Avoid heavy physical stress on the musculoskeletal system.

Venous blood is taken on an empty stomach, so you should take your last meal 8–12 hours before the procedure.

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

Contraindications

It is prohibited to conduct any diagnostic tests during menstruation. It is acceptable three days before the start of menstruation and five after its end.

It is not advisable to donate blood while using antibacterial drugs. The study is carried out a week after stopping the medication.

In other cases, the procedure is permitted.

If food intolerance is suspected, the analysis is recommended for pregnant women, hypertension and other systemic diseases.

It is prescribed to people with sleep disorders, as well as to those who work under conditions of psycho-emotional and physical stress.
