Allergies trigger IgE immune responses; intolerances affect digestion. In practice, avoid triggers, label-check, consult a clinician, and carry an epinephrine plan if prescribed. Safety: seek urgent care for severe reactions.

Food allergies are immune problems: the body’s immune system mistakes certain proteins in foods as threats and makes IgE antibodies. On exposure, mast cells release histamine and other chemicals, causing symptoms from hives to trouble breathing. Intolerances (like lactose intolerance) aren’t primarily immune-driven, they’re often enzyme defects or gut-sensitivity, so symptoms come from digestion or gut nerves rather than immune attack. Both can shape immunity by promoting gut inflammation or changing the microbiome; see an allergist/dietitian for guidance.
