Several studies have shown that healthy dietary patterns, like the Mediterranean Diet, can improve or prevent the development of chronic diseases and reduce the risk of all-cause and cardiovascular mortality. While the Mediterranean diet may have favorable effects for preventing chronic kidney disease, there is no evidence of renal protection for CKD patients. The Mediterranean Renal (MedRen) diet is an adapted version of the Mediterranean diet with reduced protein, salt, and phosphate intake, making it suitable for managing CKD stage 3.
A number of studies in the general population showed that healthy dietary patterns, such as the Mediterranean Diet, can improve or prevent the development of several chronic diseases and are associated with a significant reduction in all-cause and cardiovascular mortality. The Mediterranean diet may also have favorable effects for the prevention of chronic kidney disease (CKD), but no evidence of renoprotection exists in CKD patients. The Mediterranean Renal (MedRen) diet is an adaptation of the Mediterranean diet recommendations comprising a quantitative reduction in the RDA values of protein, salt and phosphate intake for the general population. Hence, MedRen supplies 0.8 g/Kg of protein, 6 g of salt and less than 800 mg of phosphate daily. Obviously, there is a preference for products of plant origin, which contain more alkali, fibers, unsaturated fatty acids than animal-based food. The MedRen diet can be implemented easily in mild-to-moderate stages of CKD with good results, both in terms of adherence to prescriptions and metabolic compensation. In our opinion, it should be the first step of CKD stage 3 nutritional management. This paper describes the features and reports our experience in the implementation of the MedRen diet as an early nutritional approach to CKD.
