According to the National Kidney Foundation, more than half a million people go to the emergency room for kidney stone problems. While these stones can either be passed on their own or removed with treatment, you might want to take steps to prevent kidney stones. One way you can be proactive about preventing kidney stones is to change your diet.

About Kidney Stones

Kidney stones are hard objects that are made up of the chemicals that can be found in urine. Because it is intended to remove excess water and impurities from our bodies, our urine has many different types of wastes dissolved in it. The kidneys usually eliminate these waste products and they are washed out with the liquid. However, sometimes things are out of balance.

When there is too much waste and too little liquid, those waste chemicals can form crystals. The crystals then attract other things that join together and form a solid object that continues to get longer until it is passed. That hard object is a kidney stone. Kidney stones can cause symptoms like:

  • Severe pain on either side of the lower back
  • Blood in the urine
  • Vague pain or a stomach ache that doesn’t go away
  • Nausea or vomiting
  • Fever and chills
  • Cloudy or bad-smelling urine

Types of Kidney Stones

There are four types of kidney stones that differ based on the chemicals that they are made up of. The four types of kidney stones are:

  1. Calcium oxalate kidney stones
  2. Uric acid kidney stones
  3. Struvite kidney stones
  4. Cystine kidney stones

Treating Kidney Stones

Sometimes, the stones are small enough to pass on their own but sometimes the stones must be broken up or removed by a doctor. Kidney stones can be broken up or removed with several types of treatments, including:

  • Shock wave lithotripsy
  • Cystoscopy
  • Ureteroscopy
  • Percutaneous nephrolithotomy

Along with these treatments, you can make lifestyle changes to try and prevent getting kidney stones. For instance, you can try altering your diet to prevent kidney stones. 

A Guide to Changing Your Diet to Prevent Kidney Stones

The foods you need to eat as well as the foods you need to avoid will depend on the type of kidney stones you get. Your doctor can give you more instructions about making good food choices, but for now, you can consult this basic guide to find out how to change your diet to prevent kidney stones.

Drink Water

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) suggests that if you have kidney stones, drinking enough liquid is the most important thing you can do to prevent kidney stones. You should mostly stick to water and avoid colas and other drinks with too much sugar or sodium. They recommend that unless you have kidney failure, you need to get six to eight 8 oz. glasses of water a day. It’s important to talk to your urologist first to find out how much water you should have based on your individual circumstances.

Reduce Oxalate

If you are prone to calcium oxalate stones, then the best way to change your diet to prevent kidney stones is to reduce the oxalate you consume. You probably don’t know what foods have oxalate, so here’s a list of common foods that contain this chemical:

  • Nuts and nut products
  • Peanuts (which are legumes, not nuts)
  • Spinach
  • Rhubarb
  • Wheat bran

Reduce Sodium

Eating a log of sodium increases your chances of getting kidney stones. So avoid fast food, canned food, packaged food, and processed food.

Limit Animal Protein

Eating protein that comes from animals can increase your chances of developing kidney stones, especially if you have a history of them. In the US we commonly get protein from chicken, pork, beef, fish, shellfish, and dairy products. Try reducing them to prevent kidney stones.

Get Protein from Plant Sources

While limiting animal protein is a good way to change your diet to prevent kidney stones, you still need to get plenty of protein. Luckily, there are many plant-based foods that have protein. Your doctor can go over how much protein you need to get each day and the best sources to use. Also, be sure to ask about what to avoid based on the type of stones you have. For instance, you don’t want to get your protein from tree nuts or peanuts if you have oxalate stones.

Get Plenty of Calcium from Food

Because many kidney stones contain calcium you may think you should stay away from foods that are high in calcium. However, you should get plenty of calcium from what you eat (rather than supplements). If you have the right amount of calcium, it can block substances that may lead to stones.
