In the "Plant-Based" Era, Patients With Chronic Kidney Disease Should Focus on Eating Healthy

Area of Science:

• Nephrology
• Nutritional Science
• Dietary Medicine

Background:

• Growing interest in plant-based diets necessitates understanding their impact on chronic kidney disease (CKD).
• Whole food, plant-based diets emphasize unprocessed plant foods and limit animal products.
• Evidence suggests potential benefits for CKD patients, but also highlights challenges.

Purpose of the Study:

• To review the evidence on the healthfulness of whole food, plant-based diets for patients with chronic kidney disease (CKD).
• To identify the benefits and potential drawbacks of plant-based diets in CKD management.
• To inform Nephrology providers about optimal dietary strategies for CKD patients.

Main Methods:

• Literature review of studies examining plant-based diets in CKD patients.
• Analysis of nutritional components, health outcomes, and patient-reported factors.
• Synthesis of evidence regarding benefits and challenges.

Main Results:

• Plant-based diets can reduce dietary acid load, lower potassium and phosphorus bioavailability, and increase fiber intake in CKD patients.
• These diets are associated with cardiovascular and mortality benefits.
• Challenges include preparation knowledge, cost, accessibility, and potential lower acceptability for some populations.

Conclusions:

• Liberalizing the standard CKD diet to include minimally processed plant foods like fruits, vegetables, nuts, legumes, and whole grains appears beneficial.
• Further research is required to ascertain if a strictly plant-based diet is the optimal approach for all CKD patients.
• Individualized dietary recommendations are crucial for effective CKD management.
