Remarks: Patients with Ca-Oxalate renal stones absorb and excrete an increased amount of dietary oxalate into urine than do normals. Hyperoxaluria is common in patients with malabsorption and also may occur with high intake of animal protein, gelatin, tomatoes, chocolate, cocoa, tea, calcium, strawberries, pepper, beans, beets, spinach and others. Increased Oxalate excretion is observed in vegetarians, despite low animal protein ingestion.On the other hand, Vitamin C increases oxalate excretion and may be a risk factor for calcium oxalate nephrolithiasis in patients consuming increased doses of vitamin C.
