Food Allergy Epidemiology Forecast
Food Allergy Insights and Trends
- According to DelveInsight’s analysis, the US comprised 60% of the total 7MM diagnosed prevalent cases of food allergy in 2025; these cases are expected to increase throughout the forecast period (2026–2036).
- Food allergy represents a significant and growing global public health challenge, affecting approximately 5–10% of children and adults worldwide. The prevalence varies considerably by geographic region, with Western countries reporting the highest rates.
- Self-reported food allergy consistently overestimates true prevalence because it cannot distinguish between immune-mediated reactions and other adverse food responses such as food poisoning, enzyme deficiencies, or food aversions.
- The high incidence of anaphylaxis and serious allergic reactions (SAR) among patients in the high-risk cohort underscores a significant unmet medical need.
- Food allergy prevalence may be overestimated due to reliance on self-/parent-reported data without clinical confirmation, highlighting a diagnostic gap and the need for more robust validation methods to improve prevalence accuracy.
- Food allergy burden varies by region due to differences in dietary exposure, genetic predisposition, environmental factors, and diagnostic practices. Higher seafood consumption contributes to shellfish allergy prevalence in the United States, while widespread dairy consumption and strong pediatric diagnosis rates drive milk allergy burden in the EU4 and the United Kingdom. In Japan, early-life dietary patterns and sensitization trends contribute to egg allergy dominance. These regional differences highlight the need for market-specific treatment strategies.
- There is a higher prevalence of food allergy cases among males than females in the 7MM, based on gender-specific data in 2025.
- Among EU4, Spain accounted for the largest number of diagnosed prevalent cases, whereas France had the lowest number of cases in 2025.
- Among children in the 7MM, cases of mild to moderate food allergies were more common than severe cases, whereas in adults, severe cases were more prevalent.

Food Allergy Understanding and Diagnosis Algorithm
Food Allergy Overview and Diagnosis
Food allergy is an immune response to food proteins and can be either IgE-mediated or non-IgE-mediated. IgE-mediated food allergy is a major global health concern, commonly triggered by foods such as milk, eggs, peanuts, tree nuts, fish, shellfish, wheat, and soy. Reactions can affect multiple body systems, ranging from mild symptoms like hives and vomiting to severe, life-threatening anaphylaxis. Early introduction has shown protective benefits mainly for peanut and egg allergy, while evidence for other allergenic foods remains limited.
Further details are provided in the report.
Food Allergy Diagnosis
Patients with food allergies, especially those with asthma, a history of severe reactions, or allergies to peanuts, nuts, seeds, or seafood, should carry self-injectable epinephrine and have a written emergency plan. Diagnosis involves in vivo methods such as skin-prick tests and allergy blood tests, which measure allergen-specific IgE levels. Intradermal testing is not recommended due to its high risk of false positives and severe reactions, while Atopy Patch Tests (APTs) may be helpful in specific cases like eosinophilic esophagitis. The oral food challenge remains the gold standard for confirming food allergies. In vitro testing, including sIgE blood tests like RadioAllergoSorbent Test (RAST) and Fluorescence Enzyme ImmunoAssay (FEIA), is useful when skin tests are not feasible. The advanced AllerScan test improves accuracy by detecting IgE reactivity to specific allergenic epitopes for precise food and environmental allergy profiling.

Food Allergy Epidemiology
Key Findings from Food Allergy Epidemiological Analysis and Forecast
- The total number of prevalent cases of food allergy in the 7MM ranges from approximately 45 million in 2025.
- Among the gender-specific contribution, male had the highest occurrence of cases from ~55% in 2025 in the US.
- In EU4 and the UK, maximum cases of food allergy were in Spain with ~25%, whereas the minimum number of cases were in France in 2025.
- The total number of physician diagnosed prevalent cases of food allergy in the US were ~11 million in 2025.
- In 2025, within the 7MM, on the basis of severity in adults, the number of food allergy cases was more in severe; ~8.5 million then mild to moderate. These numbers are expected to rise by 2036.
- In 2025, shellfish allergy was the most common type of food allergy in the US with the highest number of cases; ~25%.
