Coffee walnuts and pretzels with salt cause my mouth to peal what do they have in common?

Coffee, walnuts, and salted pretzels can all cause mouth peeling due to their potential to irritate the mucous membranes or cause allergic reactions in some individuals. The high acidity in coffee, the rough texture of walnuts, and the saltiness in pretzels can contribute to dryness or irritation in the mouth. Additionally, if you have a sensitivity or allergy to any of these components, that could further exacerbate the peeling. It's advisable to consult a healthcare professional if this reaction persists.
