Episode 211: Dr. John Stockman on Dietary Phosphorus and Renal Disease

In this episode, Dr. Jonathan Stockman, DVM, DACVIM (Nutrition), discusses his recent JFMS article, “Dietary phosphorus and renal disease in cats: where are we?” Throughout the conversation, Dr. Stockman explores the crucial role of phosphorus in kidney disease management and its connection to chronic kidney disease (CKD) in cats. He explains the differences between organic and inorganic phosphorus, the challenges veterinarians face in monitoring phosphorus levels in feline diets, and the risks associated with both phosphorus deficiencies and excesses. Dr. Stockman also emphasizes the importance of the calcium-to-phosphorus ratio in feline nutrition and the difficulties caregivers encounter due to unclear labeling and insufficient regulation of phosphorus content in commercial pet foods. He offers practical solutions for managing phosphorus intake and explains how informed dietary choices can help prevent or manage kidney disease, ultimately improving the quality of life for cats.
