Importance of Allergy in the Population
Allergy and food allergies affect around 30 to 40% of the population, with allergic diseases on the rise globally. These immune-mediated hypersensitivities are often associated with symptoms like watery eyes, sneezing, and in severe cases, anaphylaxis. The body's allergic responses, initially thought to be antiparasitic mechanisms, serve the purpose of expelling harmful organisms.
