What Causes Kidney Stones?

Consuming Too Much Uric Acid Or Calcium Oxalate

Consuming too much uric acid or calcium oxalate in the diet could increase a patient's risk of kidney stones. Excessive uric acid contributes to the formation of uric acid stones, and healthcare professionals suggest limiting animal protein sources such as beef, chicken, organ meats, dairy products, eggs, and fish to minimize this risk. Animal protein sources can be replaced with plant sources such as legumes, vegetables, and soy products. To prevent calcium oxalate stones and reduce the amount of calcium oxalate in the urine, doctors recommend limiting the amount of dietary calcium oxalate consumed. Foods high in this substance include spinach, wheat bran, rhubarb, and nuts (including peanuts). Along with reducing these substances, specialists often advise patients to reduce their sodium intake for optimal prevention of kidney stones.
