Greetings all! Today's question is a bit of a 'compare and contrast' with another well-known area of immune and allergy research.
We've all heard of the 'hygiene hypothesis' - the idea that decreased microbial/infectious exposure at young ages leads to increased prevalence of allergy and autoimmunity in the avoidant population.
Relevant to this discussion, could introduction of peanut, egg, and other allergenic food items at very young ages simply be to the nutritional/gastrointestinal field what the hygiene hypothesis is to the infectious diseases field? In other words, is reducing food allergy via early consumption simply another application of an established, basic immunity principle?
