When Did Food Allergies Become Common? Exploring the Rise and History of Food Allergies

Food allergies have become a significant public health concern in recent decades, but when did they actually become common? This article delves into the history and rise of food allergies, exploring scientific findings, societal changes, and environmental factors that have contributed to their increasing prevalence.

Introduction

Food allergies occur when the immune system mistakenly identifies certain food proteins as harmful, triggering an allergic reaction. While food allergies seem more prevalent today, historical records suggest they have existed for centuries, albeit less commonly diagnosed or reported.

Historical Overview of Food Allergies
