The hypothesis stems from the "empirical" observations that many patients alleviate dry mouth symptoms by the consumption of dairy products. Through its composition, the dairy product in itself provides relief for the patient, due both to its physical and biochemical properties, which could explain these observed improvements, and to elements related to the phenomena of consumption of food as an alternative to medication. In the latter case, hedonism takes on a role which has not been previously assessed. Initial work undertaken with the department of applied research at the National Dairy Industry School (ENIL) led to the prototyping of a new milk product, to qualify and adapt a product with a "health benefit" in patients suffering from xerostomia.
