Food allergy affects about 32 million people in the U.S., yet the costs and risks ripple far beyond the initial reaction. The strain shows up in everyday life too, from a quarter of people with food allergy being told to avoid foods due to concerns to millions of dollars spent each year just to keep epinephrine auto-injectors on hand. This roundup connects prevalence, emergency care, labeling rules, and treatment advances so you can see why the impact is bigger than most people expect.

- 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.
