Are Igg Food Intolerance Tests Effective?

The prevalence of adverse food reactions is increasing, and many people are attracted to food intolerance testing. These tests, whose prices are generally very high (several hundred euros), promise to diagnose your food intolerances and help you regain your health. If the use of such tools seems particularly interesting, the reality of things is much less clear. Here’s what researchers say about it.

How Food Intolerance Tests Work

After fluid extraction, food constituents are fixed to the outer layer of wells and loaded with a small amount of serum from the individual to be tried. We then, at that point, see whether antibodies and immunoglobulins G (IgG) are coordinated against these constituents. We likewise investigate the amount of these antibodies, if pertinent. 

Likewise, a test utilizing a biochip permits numerous food varieties to be estimated simultaneously. These tests then measure the presence of IgG overall. This in vitro approach, outside the body, mirrors the responses to the substances dissected. This exploratory interaction is very similar to that used to foster the blood bunch diet, which we currently know to be one-sided.

Does Measuring IgG Detect Food Intolerance?

The estimation of IgG is a little small. Four subclasses of these immunoglobulins, IgG1, IgG2, IgG3, and IgG4, all have particular natural capabilities. In this manner, assuming IgG1 might be liable for a resistant response of prejudice, IgG4 assumes the contrary part: various examinations have shown that they are created to permit the obtaining of food resilience, not bigotry. As outlandish as it might appear, IgG4 acts like an enemy of inflammatories and ought not to be related to a flighty body response.

Are In Vitro Intolerance Tests Relevant?

Furthermore, we cannot consider that the reaction in a test tube outside the human body is the same as in a complex biological fluid. In some cases, what these tests present as intolerance may be tolerance or, quite simply, mean nothing at all. 

The Food Reagents Used Do Not Represent The Reality Of The Food

The other significant problem with these tests is that extracts of food proteins are used without any exhaustive or scientific process. For example, if we test tolerance to apples, many inaccuracies remain: Which apple is it? What exact variety of fruit was used? Has the apple been cooked? What is the nature of the proteins extracted and fixed to detect IgG? All of these elements can influence the results to a large extent. 

This phenomenon causes false positives and negatives and can also explain the differences in results observed when using different biochips. Therefore, We can discover radically different intolerances depending on the laboratory where the analyses are conducted! For researchers from Cambridge in England,  food intolerance tests are not reliable. These researchers regret that companies derive financial benefits by highlighting fragmented and sometimes biased clinical studies to the public.

How Do You Know If You Have A Food Intolerance?

If intolerance tests are ineffective, how do you know if you have a food intolerance? The only truly reliable way is to implement an avoidance strategy. You must proceed as follows:

1. First, remove all suspect foods from your diet.
2. When the symptoms causing the problem improved (pain, acne, autoimmune disease, etc.), we reintroduced the foods individually.

The problem foods are usually gluten grains, animal dairy products, soy products, nightshades, or legumes.

Should We Rotate Food To Reduce The Risk Of Intolerance?

Our invulnerable framework has a memory. When presented to an antigen, it has previously been presented to it and responds quicker and all the more heartily. This rule is generally utilized for antibodies: supporters can stir and intensify the gained insusceptible guard. Turning with the expectation that the invulnerable framework “neglects” is fanciful. This cell memory can continue for some time or even throughout life, for instance, due to celiac sickness.

This peculiarity relies upon the sort of memory invulnerable cells included and different variables. This is the situation, for instance, with immune system illnesses, where we realize that various components tweak immune system assaults. Along these lines, individuals who need vitamin D or gorge salt will encounter more insusceptible assaults, paying little mind to safe memory. To avoid narrow-mindedness, it is fundamental to consider these different perspectives associated with controlling resistance.
