Low Oxalate Diet Mayo Clinic – Researchers found that eating less dietary calcium and potassium, as well as consuming less fluids, caffeine and phytate, was associated with a higher likelihood of experiencing a first symptom of a kidney stone.
According to a new Mayo Clinic study, people with diets low in calcium and potassium are more likely to develop both first-time and recurrent kidney stones. Low caffeine, phytate and fluid intake were associated with a higher incidence of symptomatic kidney stones, according to findings published in the August 1 Mayo Clinic Proceedings.

“These dietary findings may be particularly important because recommendations for kidney stone prevention are based on dietary factors that trigger early stone formation, but not initial stone formation,” said senior author Andrew Rule, a nephrologist at the Mayo Clinic in Rochester, Minnesota. Released. “Patients may not be able to adjust their diet to prevent kidney stones, but if they can prevent recurrence they are more likely to do so.”
Q&a: Reducing Your Risk Of Kidney Stones
Symptomatic kidney stones can cause severe pain, expensive medical care and surgery. According to the National Kidney Foundation, more than half a million people go to the emergency room for kidney stones each year, and it’s estimated that 1 in 10 people will develop kidney stones at some point in their lives. People with a kidney stone have about a 30 percent chance of developing another within five years.
A kidney stone is a hard substance formed from chemicals in the urine. When there is too much waste and too little fluid in the urine, crystals begin to form and combine with other elements to form a solid that turns into a kidney stone.
Symptoms may include sharp pains in your back, side, stomach, or intestines, and pink, red, or brown blood in your urine. According to the National Institute of Diabetes and Digestive and Kidney Diseases, some people may experience frequent urination, pain when urinating, inability to pass urine or little or no urine, or cloudy or foul-smelling urine. If a person experiences any of these symptoms, they should see a healthcare professional immediately.
After a person develops kidney stones, it is common for doctors to recommend dietary changes, such as eating more fruits and vegetables that are high in water. However, according to the authors, there are not many studies looking at dietary differences in people with a single case of kidney stones.

To study the effects of the diet on the two groups, researchers recruited a total of 795 people who visited the Mayo Clinic in Rochester and Florida between 2009 and 2018; Of these subjects, 411 experienced kidney stones for the first time, and the control group consisted of 384 subjects without kidney stones.
Dietary factors were assessed through a questionnaire that collected information from participants about 155 different food and beverage items. Participants were then followed for an average of 4.1 years.
When the researchers analyzed the diets of the different groups, they found that eating less dietary calcium and potassium, as well as consuming less fluid, caffeine and phytate, was associated with a higher likelihood of experiencing the first symptom of a kidney stone.
Researchers considered “low fluid intake,” which includes the water found in fruits and vegetables, to be less than 108 ounces (nine 12-ounce glasses) per day. According to the American Academy of Nutrition and Dietetics, most people get 20 percent of their fluid intake from the food they eat.
What Causes Kidney Stones?
Low caffeine is associated with a higher risk of stone formation, a link found in previous studies. A study published in the American Journal of Kidney Disease in October 2021 found that 1 to 1.5 cups of coffee per day reduced the risk of developing kidney stones by 40 percent.
Lower phytate levels have been found in people who have developed kidney stones. Phytate is an antioxidant compound found in grains, nuts and other foods that, according to the authors, aids calcium absorption and urinary calcium excretion.
During the study, 73 people had recurrent kidney stones. Recent studies have found that low levels of dietary calcium and potassium are the best predictors of stone formation. “This does not mean that increased fluid intake is essential. We did not find benefits of increased fluid intake in patients with a history of kidney stones,” said AP Chevcharat, MD, an internal medicine resident at Mount Auburn. Cambridge, Massachusetts Hospital.
Based on these findings, the authors recommend 1,200 milligrams (mg) of calcium per day for the prevention of first and recurrent kidney stones, in line with the National Institutes of Health recommendation of 1,000 to 1,200 mg per day. Adults (depending on age and gender). Dairy products, tofu and leafy vegetables are good sources of the mineral.

The authors don’t recommend a specific goal for potassium (nor does the USDA), but they do recommend eating foods high in potassium, especially vegetables and fruits.

A small pilot study suggests that patients may one day benefit from a simple urinalysis at home or in the doctor’s office… Dear Mayo Clinic: I have been struggling with kidney stones and recently found out they are calcium oxalate stones. I know I need calcium as I get older for bone health when I stop eating all dairy products. Would adding almond milk or another type of plant milk help? How should I take care of my kidneys and bones?
Answer: Your concern about milk and other dairy products can promote the development of calcium kidney stones. But people with calcium oxalate kidney stones need a certain amount of calcium in their diet.
Prevent Kidney Stones With Simple Dietary Changes
Although plant-based milks such as almond milk and soy milk contain calcium, they also contain oxalate. People with calcium oxalate stones are advised to avoid oxalate-rich foods. Cow’s milk does not contain oxalates, but it does contain calcium and many other beneficial nutrients, so it is a good choice for you.
If there is too much of these substances in the urine, the fluid in the urine dissolves and calcium oxalate forms kidney stones. When this happens, calcium and oxalate crystals form. At the same time, citrate, which prevents the formation of crystals in the urine, can create favorable conditions for the formation of kidney stones.
While calcium and oxalate cause kidney stone formation, avoiding both seems to help. But calcium is an important part of your diet. Your body not only helps keep your bones healthy, but also helps regulate your blood pressure and keep your muscles functioning. Oxalate is a naturally occurring substance in many foods. Certain fruits and vegetables, as well as nuts and chocolate, contain high oxalate levels. Your liver also produces oxalates.
The key to preventing the development of calcium oxalate stones is getting the right amount of calcium: 1,200 milligrams per day. If you include calcium-rich foods or drinks at every meal, you will reduce the amount of oxalate absorbed into your bloodstream and reduce your risk of developing new kidney stones.
Unexpected Side Effects Oxalic Acid Has On Your Body
The best food for stone prevention should be calcium. When it comes to good sources of calcium, dairy products are high on the list. Check the Nutrition Facts label to find out how much calcium is in these and other drinks and foods. But if you don’t drink milk or yogurt with meals, talk to your healthcare provider about calcium supplements or medications.
In addition to getting the right amount of calcium, there are other important changes you can make to reduce your risk of calcium oxalate kidney stones. It is important to drink plenty of water and other fluids. Drink 8 to 10 ounces of fluid every hour you wake up, or at least 2 liters per day. The easiest way to know if you are drinking enough fluids is to look at your urine. It should be reasonable.
Another important change is reducing sodium intake. Excess dietary sodium increases the risk of calcium-based kidney stones, which lead to excess calcium in the urine. Aim for less than 2,000 milligrams of sodium per day. Read labels to find out how much sodium is in the foods you eat and drink.
You may also need to cut down on oxalate-rich foods. Unfortunately, oxalate content is not listed on nutrition labels. High amounts of oxalates are found in certain fruits, vegetables and other plant foods such as beans, nuts, whole grains or bread. Oxalates are low in meat, eggs, dairy products, white rice and pasta. If you are healthy
