New Nordic Renal Diet: Nutritional Strategies for Kidney Health and Chronic Disease Management-Narrative Review

Nutrition involves the consumption of foods that provide essential nutrients and bioactive components required to enhance the quality of life; support growth and development; and maintain, protect, and improve health. A healthy diet, as defined by the World Health Organization (WHO), is an essential part of complete social, physical, and mental wellness. Results of recent studies have highlighted the existence of a variety of dietary approaches, each of which affects health outcomes differently. While general dietary habits are known to have positive impacts on health and mitigate the risks of many diseases, the potential positive and negative effects of specific dietary patterns should be carefully considered. The New Nordic Diet (NND), which is characterized by its gastronomy-focused, regional, organic, and environmentally sustainable principles, has gained popularity due to its health-promoting properties. The NND is being adapted for managing specific health conditions, such as through the New Nordic Renal Diet (NNRD), which focuses on conditions affecting kidney health. In this review we critically evaluated the current scientific evidence regarding the potential health effects of the NND and explored the application of the NNRD to support kidney health.
