Add an allergy and VitalPlate flags foods that contain it. Supported allergies include peanut, tree nut, shellfish, milk/dairy, egg, soy, fish, sesame, and wheat/gluten.
It checks ingredient lists, additive tags, and labels, and it’s careful with wording — a “dairy-free” label is read as *not* containing dairy, so it won’t be wrongly flagged.
For a serious allergy, treat VitalPlate as a helper, not a guarantee. Food data can be incomplete or wrong — always read the actual label and check for cross-contamination warnings.
