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.

Allergies caused by cuddly animals

An early determination of whether a child is sensitized to inhaled allergens such as pollen, mold or dust mites, serves as an important prognostic factor. Unfortunately, the diagnosis of small children is quite difficult to perform. Scientists from Belgium found that stuffed animals have an influence on the development of allergies in children.

Testing to identify allergies

A Belgian team of scientists tried, through a study of infants aged 0 to 2 years, to determine whether the allergies of children are based on a relation to environmental influences, or based on whether one has a family history of allergies. For this purpose, 824 infants who were previously tests with skin tests, inhaled allergens, and foods in an asthma clinic, were examined by the medical profession.

Stuffed animals make for allergies

It was determined that 40% of young children could be allergic. 28% responded to the respiratory allergens such as house dust, pollen and molds. For most young children dust mite allergens were the worst.

What the scientists also discovered is astonishing

Among children who slept with stuffed animals in bed, allergies were much more pronounced than in children who took no soft animals to bed. Factors such as gender, residence in a nursery, or eczema did not matter in the development of allergy, according to the doctors.

Sacrifice not necessary

Children love their stuffed animals, and they give them security. To take them away does not make sense. To make sure a stuffed animal does not lead to allergies, one should purchase a stuffed animal free of pollutants. Some manufacturers have already attempted to make them free of chemicals and other irritating substances. As a further preventive measure, only one stuffed animal should be taken to bed. It is also important for allergy prevention, to remember to wash soft toys regularly.
