What is the difference between food allergy and food intolerance?
A food allergy is immune-mediated and can be dangerous, including risk of anaphylaxis. A food intolerance is usually about digestion, dose, or a non-allergic reaction. They can both matter, but they are not the same problem.
If you suspect a true allergy, get medical evaluation and avoid casual self-testing. If you suspect intolerance, use a structured approach: remove the suspected trigger, let symptoms settle, then reintroduce deliberately and observe dose response. Do not turn vague discomfort into a permanently shrinking food list without evidence.
