Functional Foods and Adapted Physical Activity as New Adjuvant Therapy for Chronic Kidney Disease Patients

Background: Chronic kidney disease (CKD) will become the fifth leading cause of death in the world by 2040. It is fundamental to prevent and treat this pathology to reduce its impact on national health costs. This trial’s aim is to evaluate the effects induced by a combination of consumed functional foods (FFs) with adapted physical activity (APA) on the progression of CKD-related comorbidities. Methods: The study lasted 12 weeks. We divided 40 CKD patients into four groups: mixed (FF + APA), APA, FF and control group (usual care). The FFs were characterized by their total antioxidant capacity and antiradical activity. The APA was performed though an online training protocol, three times per week, 1 h each session. Results: At the end of the study, we observed, in the mixed group, a decrease in azotemia (p = 0.0272), diastolic blood pressure (p = 0.0169), and C-reactive protein (p = 0.0313), with increases in the FORD test (p = 0.0203) and fat free mass (p = 0.0258). The APA group showed a reduction in total cholesterol (p = 0.0039). Conclusions: The combination of FFs and APA can help counteract several CKD-related comorbidities, such as arterial hypertension, dyslipidemia and uremic sarcopenia, and improve the CKD patients’ quality of life.
