Chrononutrition in Chronic Kidney Disease.

Chrononutrition, the study of the interaction between biological rhythms and nutrition, has emerged as a promising field for addressing metabolic health. However, its role in chronic kidney disease (CKD) remains underexplored. CKD patients often experience circadian disruptions due to renal, metabolic, treatment-related, and lifestyle factors, which may influence their nutritional status and clinical outcomes.

Objective

to synthesize and analyze the existing evidence on chrononutrition in CKD patients, identify knowledge gaps, and propose directions for future research across different stages of CKD. Initially, this review contextualizes circadian physiology, alignment, and chronodisruption to explore such factors in CKD patients, focusing on chrononutrition variables already studied in the general population. We discuss how dietary timing and habit adjustments could influence CKD clinical outcomes, offering insights into circadian impacts on disease management. This new approach could optimize patient care, encouraging further research, particularly in the development of personalized strategies for different stages of the disease.
