Foods that people with urinary stones should not eat include foods with high oxalate content, foods with high calcium content, and foods with high purine content. 1. Foods with high oxalate content. Calcium oxalate stones are the most common type of stones. Oxalic acid will form oxalate with calcium in food to deposit in the patient’s body, so patients should avoid eating foods with high oxalate content. Such foods mainly include spinach, leeks, spinach, bananas, parsley, lamb, strong tea and coffee. 2. Foods with high calcium content, many urinary stones contain calcium, so patients should avoid eating foods with high calcium content. Such foods are milk, dairy products, shrimp, tofu, cauliflower, cabbage, purple kale and so on. 3. Higher purine-containing foods, some urinary calculi contain urates, and consuming higher purine-containing foods will lead to increased urate deposition in the patient’s body. Such foods are common deep-sea fish (yellow croaker, swordfish, etc.), shellfish (dried scallops, etc.), tofu, animal offal (such as liver, kidney, intestines, etc.) and other foods. For patients diagnosed with urinary stones, they should go to the relevant departments of regular hospitals as soon as possible, and be treated under the guidance of specialized physicians, so as to avoid delays and adverse consequences.
