Mediterranean Diet for Cardiovascular Risk Reduction in Chronic Kidney Disease

Abstract

The Mediterranean diet is a plant-based healthy diet similar to the vegetarian and the Dietary Approaches to Stop Hypertension diets. Unlike vegetarian and Dietary Approaches to Stop Hypertension diets, the Mediterranean diet encourages a lifestyle associated with physical activity, and social connections. In addition, the Mediterranean diet is not based on restriction of nutrients but does limit intake of processed foods. Prospective studies have confirmed that the Mediterranean diet confers primary and secondary cardiovascular disease prevention in the general population. The benefits of the Mediterranean diet lifestyle include reducing the risk of diabetes mellitus, dyslipidemia, and lowers blood pressure. In adults with CKD, adherence to the Mediterranean diet is associated with a lower risk of CKD progression and its complications such as hyperphosphatemia and metabolic acidosis, and reduces production of uremic toxins and inflammatory mediators when compared to omnivore dietary patterns. Nevertheless, prospective studies are needed to confirm the cardiovascular disease prevention with the Mediterranean diet in adults with CKD. Medical nutrition therapy remains a cornerstone of CKD management, and the Mediterranean diet could be utilized to slow CKD progression and complications.
