Question

Why do food and drink allergies still affect many people despite long human exposure?

Answer 1

Food and drink allergies persist because they are immune system responses to specific proteins that the body mistakenly identifies as harmful. Genetic predisposition, environmental factors, and changes in diet and lifestyle can influence the prevalence and severity of allergies. Additionally, the hygiene hypothesis suggests that reduced exposure to infections and microbes in early childhood may lead to a higher incidence of allergies.
