To prevent kidney stones, dietary changes depend on your specific stone type, but generally, you should limit three main things:\n\n1. High-Sodium Foods: Avoid processed meats, fast food, and canned soups. High salt increases calcium in your urine.\n2. Animal Protein: Limit red meat, poultry, and eggs. High intake can increase uric acid and stone risk.\n3. High-Oxalate Foods: If you are prone to calcium oxalate stones, reduce your intake of spinach, rhubarb, almonds, and chocolate.\n\nAdditionally, avoid sugary drinks, especially dark colas containing phosphoric acid. The most crucial step is to drink plenty of water daily. Always consult your doctor for a diet tailored to your medical history.
