This will help produce less concentrated urine and ensure a good urine volume of at least 2.5L/day.This includes any type of fluid such as water, coffee and lemonade which have been shown to have a beneficial effect with the exception of grapefruit juice and soda.Decreasing animal-based protein and eating more fruits and vegetables will help decrease urine acidity and this may help reduce the chance for uric acid stone formation. Limit alcohol because it can increase uric acid levels in the blood and avoid short term diets for the same reason. Limit sugar-sweetened foods and drinks, especially those that have high fructose corn syrup. Follow a healthy diet plan that has mostly vegetables and fruits, whole grains, and low-fat dairy products. To prevent uric acid stones, cut down on high-purine foods such as red meat, organ meats, beer/alcoholic beverages, meat-based gravies, sardines, anchovies and shellfish. The high acid concentration of the urine makes it easier for uric acid stones to form. Higher uric acid excretion leads to more acidic urine. High purine intake leads to a higher production of uric acid and a larger acid load for the kidneys to excrete. Red meat, organ meats, and shellfish have high amounts of a natural chemical compound known as purines. You can lower your sodium intake by choosing fresh low sodium foods which can help to lower calcium leakage in the urine and will also help with blood pressure control if you have high blood pressure.Ģ. There are many sources of "hidden" sodium such as canned or commercially processed foods as well as restaurant-prepared and fast foods. Therefore, a high sodium diet can increase your chances for developing another stone. Sodium and calcium share the same transport in the kidney so if you eat high sodium foods it will increase calcium leakage in the urine. The recommended calcium intake to prevent calcium stones is 1000-1200 mg per day (you can eat 3 servings of dairy products with meals to meet the recommendation).Įxtra sodium causes you to lose more calcium in your urine. Work to cut back on the sodium in your diet and to pair calcium-rich foods with oxalate-rich foods. A diet low in calcium actually increases your chances of developing kidney stones.ĭon't reduce the calcium in your diet. This will make it less likely that kidney stones will form.Ĭalcium is not the enemy but it tends to get a bad rap! This is most likely due to its name and misunderstanding that calcium is the main cause in calcium-oxalate stones. The oxalate and calcium from the foods are more likely to bind to one another in the stomach and intestines before entering the kidneys. Limiting intake of these foods may be beneficial for people who form calcium oxalate stones which is the leading type of kidney stone.Įat and drink calcium foods such as milk, yogurt, and some cheese and oxalate-rich foods together during a meal. Some examples of foods that have high levels of oxalate include peanuts, rhubarb, spinach, beets, Swiss chard, chocolate and sweet potatoes. Oxalate is naturally found in many foods, including fruits and vegetables, nuts and seeds, grains, legumes, and even chocolate and tea. Calcium Oxalate Stones: most common stones Most diet recommendations are based on stone types and individualized for each person.ġ. There is no single diet plan for stone prevention. Try to avoid sodas (especially those with high amounts of fructose), sweetened iced tea and grapefruit juice. Speak with a healthcare professional about the right amount of water that's best for you. You should drink 2-3 quarts of liquid or 8-12 cups per day to produce a good amount of urine. Be sure to keep well hydrated, especially when doing exercise or activities that cause a lot of sweating. The more you sweat, the less you will urinate, which allows stone-causing minerals to settle and deposit in the kidneys and urinary tract. Why? Loss of water through sweating whether due to these activities or just the heat of summer may lead to less urine production. This will help make sure that you urinate frequently to avoid any build up of calcium or uric acid.ĭon't underestimate your sweat! Saunas, hot yoga and heavy exercise may sound good for your health, but they also may lead to kidney stones. One of the best things you can do to avoid kidney stones is to drink plenty of water every day.
