This umbrella review consolidates evidence from 28 systematic reviews and meta-analyses on dietary patterns and kidney health. It highlights that a low-protein diet (LPD) reduces proteinuria in chronic kidney disease (CKD) patients, while a very low-protein diet (VLPD) decreases end-stage renal disease occurrence. Notably, lower sodium intake significantly reduces urinary sodium and protein excretion.
Key findings
- A low-protein diet reduced proteinuria in CKD patients.
- A very low-protein diet decreased the occurrence of end-stage renal disease.
- Lower sodium intake significantly reduced urinary sodium and protein excretion.
- Both the Mediterranean and DASH diets mitigated the risk of CKD.
Why it matters
Understanding the impact of dietary patterns on kidney health is crucial for clinicians, as dietary modifications can play a significant role in the management and prevention of chronic kidney disease and its complications.
