Food allergies have been on the rise globally over the past few decades, prompting scientists, healthcare professionals, and consumers alike to ask an important question: Are we allergic to food itself, or to what has been done to it? As food production has evolved, we have seen a dramatic shift in the way our food is grown, processed, and packaged.
Genetically modified organisms (GMOs), artificial preservatives, and chemical additives have become common in modern food. But do these alterations play a role in the increasing incidence of food allergies? In this article, we explore the relationship between food allergies, GMOs, and food processing.

The Growing Prevalence of Food Allergies
Food allergies are an abnormal immune response to certain proteins found in foods. When a person with a food allergy consumes an allergenic protein, their immune system misidentifies it as harmful, releasing chemicals like histamines that cause symptoms ranging from mild reactions (such as itching or swelling) to severe anaphylaxis, a potentially life-threatening condition.
The prevalence of food allergies, especially in children, has grown significantly. According to the Centers for Disease Control and Prevention (CDC), food allergies among children increased by 50% between 1997 and 2011. The most common food allergens include:
Peanuts
Tree nuts
Milk
Eggs
Wheat
Soy
Fish and shellfish
While food allergies have likely existed for centuries, the rapid rise in cases over the past few decades has led to concerns that modern food production methods may be exacerbating this trend.
What Are GMOs?
Genetically modified organisms (GMOs) are plants, animals, or microorganisms that have had their genetic material altered in a laboratory using genetic engineering techniques. The purpose of this modification is often to enhance certain desirable traits, such as increased resistance to pests, tolerance to herbicides, or improved nutritional content. While GMOs are widely used in agriculture, they have become a point of contention due to concerns about their long-term health and environmental effects.
The most common GMO crops in the United States include:
Corn: Genetically modified to resist pests and tolerate herbicides.
Soybeans: Engineered for herbicide resistance.
Canola: Modified to produce oils with improved nutritional profiles.
Cotton: Developed to be pest-resistant.
