Diet and Chronic Kidney Disease.

Area of Science:

• Nephrology
• Nutrition Science
• Public Health

Background:

• Chronic kidney disease (CKD) affects 15% of US adults, with rising prevalence linked to aging and obesity.
• The Western diet, high in animal protein and low in produce, contributes to chronic disease, including CKD.
• Dietary factors significantly influence kidney health and disease progression.

Purpose of the Study:

• To review mechanisms linking Western diet characteristics to kidney disease incidence and progression.
• To explore how dietary patterns impact kidney function and health outcomes.
• To identify potential dietary interventions for managing and preventing CKD.

Main Methods:

• Literature review of studies examining the impact of diet on kidney disease.
• Analysis of the physiological effects of high animal protein and low produce intake on the kidneys.
• Examination of the relationship between diet, acid production, and kidney workload.

Main Results:

• High animal protein intake can cause hemodynamic injury to the glomerulus.
• Low fruit and vegetable intake, coupled with high animal protein, increases acid production, straining kidney function.
• Dietary modifications, such as reduced animal protein and increased plant-based foods, may prevent or delay end-stage renal disease.

Conclusions:

• Key features of the Western diet may negatively impact kidney disease.
• Dietary changes, including reduced animal protein and increased fruits, vegetables, and fiber, show potential for CKD prevention and management.
• Further clinical trials are needed to establish optimal dietary patterns for CKD.
