Strict avoidance – the best way to treat and prevent food allergies?

Identification of biomarkers is needed for patients who react to food

In a recent study, scientists identified a prestigious American university asking if strict allergen avoidance is the most appropriate strategy for dealing with food allergies. Traditionally, avoiding the foods which one cannot tolerate has been a standard treatment for allergies to food. This advice is based on the assumption that contact can lead to an allergic reaction and avoidance accelerates the recovery. Recent studies make this assumption.

Heat largely kills allergens

Recent studies show that most children with a milk allergy tolerate eggs and similar foods when they were hot. In addition, clinical studies show that eating tiny amounts of food could result in desensitization. It must be noted at this point that this procedure can be naturally carried out in the presence of a physician or an at an allergy clinic when a child suffers from severe allergic reactions.

Late introduction of allergens offers no advantage

Recently published epidemiological studies do not support the previous assumption that a delayed introduction of highly allergenic foods for infants and young children prevents food allergies. In fact, the recent data suggest that delaying the introduction of certain foods may even increase the risk of developing an allergy.

Biomarkers could provide a better understanding

The latest data suggest that strict allergen avoidance as a treatment is not always necessary. Exposure to a particular food can even be a therapeutic measure. An extended delay in the introduction of food allergens in the diet of young children may increase the risk of allergies as shared by scientists in their report. In many cases, the strict avoidance of a treatment is clearly necessary, however, so the scientists at the Mount Sinai Hospital continue to state, that further studies are needed to assess risks and benefits of exposure to allergens in more detail. They agree that the identification of biomarkers is needed for patients who react to food.
