Low saliva production and your diet
Saliva is crucial to processing of food in the mouth, including the sensory and textural experience. The production and properties of saliva change with age, and this can result in dry mouth and taste abnormalities. Such changes may result in reduced nutrient intake and malnutrition besides adversely affecting the quality of life.
