Food Allergy Epidemiology Forecast

Food Allergy Insights and Trends

• According to DelveInsight’s analysis, the total diagnosed prevalent cases of Food Allergy were ~61,000,000  in the 7MM (the United States, the EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan) in 2025.
• Food allergy is more prevalent in Asian countries such as Japan due to changing dietary habits, increased urbanization, environmental exposures, genetic susceptibility, and improved awareness and diagnosis of allergic conditions. 
• Mild-to-moderate food allergy was more prevalent, affecting about 31 million individuals across the 7MM in 2025, with trends indicating a steady increase in cases over the 2022–2036 period.
• Adults face a higher risk of developing food allergies compared to children in the US, with factors such as changing dietary patterns, cumulative environmental exposures, underlying comorbidities, and increased awareness and diagnosis contributing to the rising incidence in this population.

Increasing prevalence, lifestyle changes, growing consumption of processed foods, and heightened environmental risk factors are expected to sustain the global burden of food allergy over the next decade. Improving early diagnosis, enhancing patient education, and expanding access to emerging immunotherapies will be key factors shaping future management trends.

Food Allergy Understanding and Diagnosis Algorithm

Food Allergy Overview

Food allergy is an immune-mediated condition that occurs when the body mistakenly identifies certain food proteins as harmful, triggering an abnormal immune response. It can range from mild to severe, with symptoms such as itching, hives, swelling, abdominal pain, vomiting, and diarrhea, and in severe cases, anaphylaxis, which may involve difficulty breathing, a drop in blood pressure, and can be life-threatening. Food allergy is primarily caused by exposure to common allergens such as peanuts, tree nuts, milk, eggs, wheat, soy, fish, and shellfish. It typically develops due to a combination of genetic and environmental factors.

Food Allergy Diagnosis

Food allergy is diagnosed primarily through clinical evaluation and detailed patient history, focusing on reproducible symptoms such as urticaria, gastrointestinal distress, respiratory difficulty, or anaphylaxis following food exposure. Diagnostic tests, including skin prick testing and serum-specific immunoglobulin E (IgE) measurements, help confirm sensitization, while oral food challenge remains the gold standard for definitive diagnosis.
