FEEL GOOD AFTER EVERY MEAL Living with histamine intolerance or MCAS means every food is a question mark. HistaScan gives you a clear, instant answer โ just scan. SCAN ANY FOOD, THREE WAYS โข Barcode โ check any packaged product in seconds โข Ingredient label (OCR) โ snap the label for an instant breakdown โข Dish / plate photo โ analyze a whole meal from one picture HISTAMINE, OXALATES AND SALICYLATES Most apps only look at histamine.
