OBJECTIVE: The treatment of chronic kidney disease (CKD) consists of pharmacological, nutritional, and psychological-social approaches. The dietary therapy of CKD, namely a low-protein low-phosphorus diet, plays a crucial role in contributing to delay the onset of end-stage renal disease (ESRD) and to protect cardiovascular and nutritional status. The protein-free food products represent a very important tool for the implementation of a low-protein diet to ensure adequate energy supply, reducing the production of nitrogenous waste products. METHODS: This survey included 100 consecutive CKD patients who were asked their opinion about the use of protein-free foods. RESULTS: Ninety-eight patients (98%) reported a regular daily intake of protein-free pasta (as macaroni, spaghetti, etc.), which was the preferred product consumed. Actually, the taste and texture of protein-free pasta were considered as "good" or "very good" by 70% of patients. Conversely, 43% of CKD patients perceived the taste and texture of protein-free bread as "bad" or "very bad", and 30% found it "acceptable". Therefore, the main concern for the implementation of low-protein diets is the use and palatability of the protein-free products, bread in particular. CONCLUSIONS: The use of these products may help in reducing protein, phosphorus, and sodium intake while supplying an adequate energy intake, which represents the basis for a nutritionally safe and successful dietary treatment of advanced CKD patients. Manufacturers and food technology should make more efforts to finding new solutions to improve the taste and texture of protein-free products.
