Kidney stones are a painful reality for many people. But did you know that there are certain foods that can increase your risk of developing kidney stones? In this article, we'll take a look at some of the most common offenders and what you can do to avoid them.

Types of kidney stones

There are four main types of kidney stones: calcium oxalate, uric acid, struvite, and cystine. Calcium oxalate kidney stones are the most common type of kidney stone, accounting for about 80% of all kidney stones. Uric acid kidney stones make up about 5-10% of all kidney stones. Struvite kidney stones make up about 10-15% of all kidney stones, and cystine kidney stones make up about 1-2% of all kidney stones.

Foods that cause kidney stones

If you're prone to kidney stones, there are certain foods you should avoid. Here are some of the worst offenders:

1. Sugar. Too much sugar can lead to kidney stones, because it causes your body to excrete more calcium in your urine.

2. Alcohol. Drinking alcohol can also increase your risk of kidney stones, because it dehydrates you and makes your urine more concentrated.

3. Caffeine. Caffeine is a diuretic, so it can also dehydrate you and make your urine more concentrated.

4. Salt. A high-sodium diet can cause kidney stones, because it increases the amount of calcium in your urine.

5. Animal protein. Animal protein is high in purines, which can break down into uric acid and increase your risk of kidney stones.

How to prevent kidney stones

Kidney stones are a painful condition that can be caused by a variety of different foods. While there is no sure way to prevent kidney stones, there are some things you can do to reduce your risk.

Cut back on salt. Too much salt can increase the amount of calcium in your urine, which can lead to kidney stones.

Drink plenty of fluids. Drinking plenty of fluids helps flush out the kidneys and can help prevent kidney stones from forming.

Eat more calcium-rich foods. Calcium helps bind oxalate in the intestine, which can help prevent it from being absorbed into the body and forming kidney stones.

Avoid high-oxalate foods. Oxalate is a substance found in some foods that can contribute to kidney stones. Some high-oxalate foods include spinach, nuts, and chocolate.

Talk to your doctor if you think you may be at risk for kidney stones. There are some medical conditions that can increase your risk of developing kidney stones. Your doctor can help you determine if you are at risk and offer suggestions for preventing kidney stones.


Kidney stones are a painful reality for many people, but there are ways to reduce your risk of developing them. By avoiding foods that are high in oxalates and calcium, you can help keep kidney stones from forming. And if you do develop kidney stones, there are treatments available to help relieve the pain and get rid of them for good.||
