[TECHNICAL CHARACTERISTICS OF SPECIFIC FOOD PRODUCTS FOR PATIENTS WITH DYSPHAGIA].

Dysphagia is a common problem among elderly and also in some pathological conditions such as neurodegenerative diseases or tumors. Making an adequate diet for this disease may present some difficulties. The aim of this document is to make a detailed technical report about the characteristics of the products that are available in Spain to hydrate and to feed patients with dysphagia. Food and pharmaceutical industries have developed a range of products designed to ensure homogeneous texture and a suitable viscosity to guaranty an adequate hydration. An adequate nutritional status is also achieved with these products for patients with dysphagia, without compromising their safety. The ingredients used to achieve a suitable viscosity are different types of starches, gums and other substances. It has been developed thickeners and gellified water for hydratation, and in case of food there are purees (dehydrated, lyophilized, pasteurized and sterilized), fruit purees, fruit pudding, and dehydrated cereal. Patients who do not meet their nutritional needs have also oral supplements with different viscosities. The industry offers extensive information about the technical characteristics of the products, except for viscosity. It would be recommended for the manufacturers to include in detail the technical specifications of the used methodology and the measurement and the results obtained in the analysis of viscosity that can be consulted by professionals of the Clinical Nutrition and Dietetics Units who treat these patients.
