Can I help prevent kidney stones by changing what I eat or drink?
- Posted On:
According to the National Institutes of Health, drinking enough liquid, mainly water, is the most important thing you can do to prevent kidney stones. Unless you have kidney failure, many healthcare professionals recommend that you drink six to eight, 8-ounce glasses a day. Talk with a healthcare professional at CCMG Urology about how much liquid you should drink.
Studies have shown that the Dietary Approaches to Stop Hypertension (DASH) diet can reduce the risk of kidney stones. Studies have shown that being overweight increases your risk of kidney stones. A dietitian can help you plan meals to help you lose weight.
Does the type of kidney stone I had affect food choices I should make?
Yes. If you have already had kidney stones, ask your health care professional which type of kidney stone you had. Based on the type of kidney stone you had, you may be able to prevent kidney stones by making changes in how much sodium, animal protein, calcium, or oxalate is in the food you eat.
You may need to change what you eat and drink for these types of kidney stones:
A dietitian who specializes in kidney stone prevention can help you plan meals to prevent kidney stones.
Calcium Oxalate or Phosphate Stones
Reduce oxalate and sodium
If you’ve had calcium oxalate stones, you may want to avoid these foods to help reduce the amount of oxalate in your urine:
nuts and nut products
peanuts—which are legumes, not nuts, and are high in oxalate
rhubarb
spinach
wheat bran
Talk with a healthcare professional about other food sources of oxalate and how much oxalate should be in what you eat.
Reduce sodium
Your chance of developing kidney stones increases when you eat more sodium. Sodium is a part of salt. Sodium is in many canned, packaged, and fast foods. It is also in many condiments, seasonings, and meats.
Talk with a healthcare professional about how much sodium should be in what you eat. See tips to reduce your sodium intake.
Limit animal protein
Eating animal protein may increase your chances of developing kidney stones.
A healthcare professional may tell you to limit eating animal protein, including
beef, chicken, and pork, especially organ meats
eggs
fish and shellfish
milk, cheese, and other dairy products
Although you may need to limit how much animal protein you eat each day, you still need to make sure you get enough protein. Consider replacing some of the meat and animal protein you would typically eat with beans, dried peas, and lentils, which are plant-based foods that are high in protein and low in oxalate.
Talk with a healthcare professional about how much total protein you should eat and how much should come from animal or plant-based foods.
Get enough calcium from foods
Even though calcium sounds like it would be the cause of calcium stones, it’s not. In the right amounts, calcium can block other substances in the digestive tract that may cause stones. Talk with a healthcare professional about how much calcium you should eat to help prevent getting more calcium oxalate stones and to support strong bones. It may be best to get calcium from low-oxalate, plant-based foods such as calcium-fortified juices, cereals, breads, some kinds of vegetables, and some types of beans. Ask a dietitian or other health care professional which foods are the best sources of calcium for you.
Uric Acid Stones
Limit animal protein
Eating animal protein may increase your chances of developing kidney stones.
A healthcare professional may tell you to limit eating animal protein, including
beef, chicken, and pork, especially organ meats
eggs
fish and shellfish
milk, cheese, and other dairy products
Although you may need to limit how much animal protein you have each day, you still need to make sure you get enough protein. Consider replacing some of the meat and animal protein you would typically eat with some of these plant-based foods that are high in protein:
legumes such as beans, dried peas, lentils, and peanuts
soy foods, such as soy milk, soy nut butter, and tofu
nuts and nut products, such as almonds and almond butter, cashews and cashew butter, walnuts, and pistachios
sunflower seeds
Talk with a healthcare professional about how much total protein you should eat and how much should come from animal or plant-based foods.
Losing weight if you are overweight is especially important for people who have had uric acid stones.
Cystine Stones
Drinking enough liquid, mainly water, is the most important lifestyle change you can make to prevent cystine stones. Talk with a healthcare professional about how much liquid you should drink.
