Food Intolerance


Sometimes, certain people have an unusual reaction to a particular food or food ingredient!

What is food intolerance?

Over the last 25 years, numerous studies indicated that 55% of the world population manifest hypersensitivity – an abnormal reaction of the body to certain food and drink ingredients that are consumed daily. IgG intolerance is an immune response in which IgG IgG antibodies – are generated.It is a chronic long-term response of the body that does not endanger the life of the patient, but it has been proven that it might be the cause of other diseases or chronic conditions, such as arthritis, asthma, candidiasis, celiac disease, chronic fatigue syndrome, depression, anxiety, digestive problems, water retention in the body, swelling, ear infection, sinusitis, fibromyalgia, migraine headaches, dizziness, insomnia, muscle pain, mental fatigue, psoriasis, obesity or weight loss. This reaction of the body is called intolerance and may be congenital or acquired.

Metabolic i.e. innate intolerance occurs as a result of deficiency or decrease in some enzyme activity, as a result of the inherent error in the genetic code of one of the enzymes, involved in the complex metabolic processes. This disorder occurs in infants and the diagnosis is confirmed genetically at the molecular level.

How does it occur?

As a consequence of stress, medication, and infections, which can cause damage to the colon wall. This results in undigested food passing into the bloodstream, which causes a production of specific IgG antibodies and formation of immune complexes, which eventually is manifested by the occurrence of chronic inflammation reactions – as the very basis of this change.

Typical symptoms

  •  Chronic gastrointestinal problems: diarrhea, constipation, abdominal pain, flatulence, irritable bowel syndrome, colic, bloating.
  •  Headaches, migraines.
  •  Rheumatic diseases, joint pain..
  •  Chronic skin disorders: atopic dermatitis, psoriasis, pruritus, urticaria.
  •  Food intolerance is not the same as a food allergy

Although food intolerance and allergies manifest same or similar symptoms, they are completely different conditions. Learn more about the differences in the table below:

Acute beginningDelayed start, chronic form
Positive allergotestsNegative allergotests
Suspicion about 1-2 ingredientsSuspicion about several food ingredients
Very small amount of food is sufficientDepending on the quantity
Affects the skin and mucosaAffects all tissues
Easily identifiableHard to identify
Permanent (definitive)Remission is possible if that type of food is avoided and proper diet is followed

Intolerance test IgG

Avicena Laboratory Вoffers offers a complete laboratory evaluation of your health, using tests which are тестови most modern equipment and in the shortest possible time.

RIDASCREEN® Spec.IgG FoodScreen test is the most reliable,&nbspmost efficient and the safest test for determining what is causing your symptoms.

  • Noninvasive
  • Simple blood draw
  • Same day results
  • Test that determines possible intolerance of over 90 types of food or food ingredients

Studies have shown that two thirds of patients undergoing food intolerance test are free from chronic pain, which significantly influence the overall health of each patient’s well-being.

What after receiving the results?

1. Avoiding food for which specific IgG are detected..

All food that has a positive result on the test should be completely avoided, from 8-12 weeks up to one year, depending on the body’s reaction.

2. Rotational diet with other food.

The other food is consumed in a 4-day cycle. (ex: if you eat certain food one day, avoid the same food in the next 3 days).

3. Reintroducing the avoided food back into the diet.

The food that has been avoided is gradually reintroduced in the diet. If food reaction re-appears, that food should not be on the menu. (it can be consumed, but not often).
