Plant-Based Diets and Peritoneal Dialysis: A Review

Area of Science:

• Nephrology
• Dietary Science
• Public Health

Background:

• Whole food plant-based diets are increasingly recognized for managing chronic health conditions.
• Their application in end-stage kidney disease (ESKD) and specifically peritoneal dialysis (PD) populations remains under-explored.
• Growing public interest necessitates understanding these diets in PD patients.

Purpose of the Study:

• To review the potential benefits and safety concerns of increasing plant consumption in patients undergoing peritoneal dialysis.
• To provide clinicians with information regarding plant-based diets for PD patients.

Main Methods:

• Literature review of studies on plant-based diets, chronic kidney disease, and peritoneal dialysis.
• Analysis of potential nutritional, metabolic, and clinical impacts.

Main Results:

• Plant-based diets may offer benefits such as improved cardiovascular health and nutrient intake for PD patients.
• Potential concerns include adequate protein and micronutrient intake, and electrolyte balance.
• Further research is needed to establish optimal plant-based dietary patterns for PD.

Conclusions:

• Increasing plant consumption in PD patients may be beneficial but requires careful consideration of nutritional adequacy and potential risks.
• Personalized dietary guidance is crucial for PD patients adopting plant-based diets.
• Evidence gaps highlight the need for targeted research in this area.
