5 Foods to Prevent Kidney Stones
You may add a specific food to reduce kidney stones into your routine diet. Here is the list of 5 foods that you may consume.
1. Lemon. Lemons are high in citric acid, which helps to prevent kidney stones from forming. Lemonade is always refreshing, but commercial brands are high in sugar. The healthiest way to consume lemons is to squeeze fresh lemon into water.
2. Milk. Although calcium oxalate stones are produced when calcium binds with oxalates, this doesn’t mean you should avoid calcium in your diet. In fact, consuming high calcium dairy products such as milk has been linked to a lower risk for kidney stones. It is best to consume calcium foods at the same time consuming foods with oxalates so that the calcium and oxalates have a better chance of combining in the intestines and passing with a bowel movement rather than passing into the kidneys.
3. Oatmeal. This is a common breakfast food to reduce kidney stones, high in fiber, and rich in magnesium. Oats are also a low oxalate food. you can make it even healthier by adding milk and some nuts, seeds, and fruits that are low oxalate, such as blueberries, walnuts, pumpkin seeds, or flax seeds. It’s best to buy pure oats or plain oatmeal, not commercial mixes that may include all kinds of additives and sweeteners.
4. Cabbage. Low oxalate vegetables such as cabbage are helpful for preventing calcium oxalate stones. Cabbage is high in phytonutrients and important vitamins such as Vitamin K, B6, and folic acid. It’s also a high fiber food, which helps fill you up and makes it less likely you’ll be tempted to overeat less healthy foods.
5. Apples. Apples and apple juice are another refreshing fruit that can be beneficial for kidney stones. They are a low oxalate fruit that is high in antioxidants such as Vitamin C and rich in fiber.
