Traditional dietary management of chronic kidney disease (CKD) focuses on the quantity within the diet of energy and protein, and the restriction of single micronutrients, with little mention of dietary quality. Dietary patterns that are more plant-based, lower in meat (including processed meat), sodium and refined sugar, and have a higher content of grains and fibres are now included in multiple clinical guidelines for chronic disease prevention. The Mediterranean diet (MD) has been associated with reduced cardiovascular disease incidence in both observational and interventional studies. A wealth of evidence links MD with other beneficial effects on chronic diseases such as diabetes, obesity or cognitive health. This review examines each constituent of the classical MD and evaluates their suitability for the management of patients with CKD. We also evaluate the potential hyperkalaemia risk of increasing fruit and vegetable intake. Overall, a decrease in net endogenous acid production and increase in fibre may lead to a better control of metabolic acidosis. This, together with other putative favourable effects of MD on endothelial function, inflammation, lipid profile and blood pressure, provide mechanistic pathways to explain the observed reduced renal function decline and improved survival in CKD patients adhering to an MD.

Traditional dietary recommendations for patients with chronic kidney disease (CKD) focus on the quantity of nutrients consumed. Without appropriate dietary counselling, these restrictions can result in a low intake of fruits and vegetables and a lack of diversity in the diet. Plant nutrients and plant-based diets could have beneficial effects in patients with CKD: increased fibre intake shifts the gut microbiota towards reduced production of uraemic toxins; plant fats, particularly olive oil, have anti-atherogenic effects; plant anions might mitigate metabolic acidosis and slow CKD progression; and as plant phosphorus has a lower bioavailability than animal phosphorus, plant-based diets might enable better control of hyperphosphataemia. Current evidence suggests that promoting the adoption of plant-based diets has few risks but potential benefits for the primary prevention of CKD, as well as for delaying progression in patients with CKD G3-5. These diets might also help to manage and prevent some of the symptoms and metabolic complications of CKD. We suggest that restriction of plant foods as a strategy to prevent hyperkalaemia or undernutrition should be individualized to avoid depriving patients with CKD of these potential beneficial effects of plant-based diets. However, research is needed to address knowledge gaps, particularly regarding the relevance and extent of diet-induced hyperkalaemia in patients undergoing dialysis. Emerging evidence suggests that plant-based diets could help to prevent chronic kidney disease (CKD), manage its symptoms and metabolic complications and delay disease progression. Here, the authors discuss the potential risks and benefits of these diets in patients with CKD, as well as implementation strategies and knowledge gaps.

Retarding chronic kidney disease (CKD) progression: a practical nutritional approach for non-dialysis CKD
(2016) Sezer, Siren; Bellizzi, Vincenzo; Carrero, Jan Jesus; Chauveau, Philippe; Cozzolino, Mario; Cupisti, Adamasco; D'Alessandro, Claudia; De Nicola, Luca; Fiaccadori, Enrico; Johansson, Lina; Minutolo, Roberto; Molina, Pablo; Ter Wee, Pieter; Teta, Daniel; Wanner, Christoph; Calella, Patrizia; Fouque, Denis
This is a case report on a patient with non-dialysis chronic kidney disease (CKD) in whom several nutritional issues are briefly discussed from a practical point of view. The article is accompanied by an editorial published in this Journal in relation to the 2nd International Conference of the European Renal Nutrition working group at ERA-EDTA-" Retarding CKD progression: readily available through comprehensive nutritional management?"and focuses on several practical topics associated with the nutritional approach for the conservative treatment of non-dialysis CKD. The article is divided into 3 sections-basic nutritional assessment, nutritional targets, and nutritional follow-up in non-dialysis CKD-linked to 3 consecutive steps of the clinical follow-up of the patient and the related nutritional concerns and intervention. First visit: Baseline nutritional assessment and basic nutritional considerations in non-dialysis chronic kidney disease (CKD) What nutritional assessment/monitoring for protein-energy wasting (PEW) should be employed? Is a body mass index (BMI) of 21 kg/m2 adequate? What phosphate target should be pursued? What are the nutritional habits in patients with incident CKD? What protein needs and amount of dietary protein should be pursued? Does the quality of protein matter? What amount of dietary salt should be employed? How should this be obtained? How should normal serum phosphate be achieved? What diet should be recommended? Is a vegetarian diet an option? Second visit: Major nutritional targets in non-dialysis CKD Consequences of unintentional weight loss What is the role of the renal dietitian in helping the patient adhere to a renal diet? Intermediate visits: Nutritional follow-up in non-dialysis CKD What treatment for calcium/parathyroid hormone (PTH) will affect CKD progression? Final visits: Would a dietary recall/intensive dietary education improve adherence with the diet? Would a very-low-protein diet (VLPD)/ketodiet be indicated for this patient?
