Key Takeaways
- 32 million people in the U.S. are estimated to have food allergies (about 10% of adults and 5% of children), according to a 2021–2022 review of U.S. prevalence estimates.
- 4% of adults in the U.S. are estimated to have food allergies, per CDC’s review of prevalence estimates.
- 13% of U.S. children with food allergy report having eczema, per a study summary using the NCHS National Health Interview Survey data.
- $29.3 billion in total societal costs of food allergy in the U.S. in 2013, including direct and indirect costs, per the same peer-reviewed economic analysis.
- Food allergy results in an estimated $4.2 billion in annual costs in the U.S. for epinephrine auto-injectors, according to a 2017 budget-impact/cost review using spending estimates.
- Families of children with food allergy report an average of 2.5 more healthcare visits per year than families without food allergy (U.S. insurance claims analysis).
- 32% of food-allergic consumers reported not knowing the correct use of epinephrine auto-injectors in a U.S. survey study published in 2020.
- A 2021 study found that only 54% of caregivers reported having an epinephrine auto-injector available at all times for their food-allergic child.
- In a 2019 U.S. survey, 42% of families with food-allergic children reported experiencing delays in accessing allergy specialists.
- In a 2020 survey, 63% of foodservice operators reported implementing cross-contact prevention practices after receiving formal training on food allergies.
- The global food allergy therapeutics market was valued at $1.9 billion in 2023 and projected to grow to $4.7 billion by 2030, per a market research report using publicly disclosed data.
- The global oral immunotherapy market for allergies was projected to reach $11.2 billion by 2030 (forecast from a 2023 baseline) in a published industry outlook.
- In the U.S., 1–2% of emergency department visits are associated with food allergy symptoms (anaphylaxis and allergic reactions combined), according to an NIAID report summary cited by CDC.
- In a 2018 systematic review, anaphylaxis triggered by food accounted for 30–40% of all anaphylaxis cases across included studies.
- In a large U.K. cohort study, 30% of fatal or near-fatal anaphylaxis cases were attributable to food allergens.
Food allergies affect millions, drive major healthcare costs, and make label and epinephrine access crucial.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
