Kidney Stone Diet Goals

How Can I Prevent Kidney Stones? | Duke Health

The goals of the kidney stone diet really boil down to 4 distinct outcomes. Each of the kidney stone diet components works to get us to at least one of these goals.

  • Increase urine volume
  • Increase urine pH to a healthy range
  • Reduce urine calcium
  • Reduce urine oxalate
  • A healthy kidney stone diet is different for every single person. A 24-hour urine test is critical to know what pieces of nutrition for calcium oxalate stones will matter for you!

    How Many Days Does It Take For A Kidney Stone To Pass

    A stone thats smaller than 4 mm may pass within one to two weeks. A stone thats larger than 4 mm could take about two to three weeks to completely pass. Once the stone reaches the bladder, it typically passes within a few days, but may take longer, especially in an older man with a large prostate.

    It’s Not Just The Oxalate

    Oxalate is naturally found in many foods, including fruits and vegetables, nuts and seeds, grains, legumes, and even chocolate and tea. Some examples of foods that contain high levels of oxalate include: peanuts, rhubarb, spinach, beets, chocolate and sweet potatoes. Moderating intake of these foods may be beneficial for people who form calcium oxalate stones, the leading type of kidney stones.

    A common misconception is that cutting the oxalate-rich foods in your diet alone will reduce the likelihood of forming calcium oxalate kidney stones. While in theory this might be true, this approach isn’t smart from an overall health perspective. Most kidney stones are formed when oxalate binds to calcium while urine is produced by the kidneys.

    It is important to eat and drink calcium and oxalate-rich foods together during a meal. In doing so, oxalate and calcium are more likely to bind to one another in the stomach and intestines before the kidneys begin processing, making it less likely that kidney stones will form.

    Best Foods To Try When You Have Kidney Stones

    When the type of stone is not known, you may consider the following points helpful-

    1. Water It is very important to stay hydrated when you have kidney stones. Your doctor may recommend a fixed amount of water that you need to drink daily, try to stick to this recommendation.

    2. Lemons Lemons are a great source of citrate which is thought to make the urine less acidic. Uric acid stones can form and grow when urine is acidic hence lemons and limes are great for dissolving these stones if they form. Lemon juice should be diluted with water and can be taken.

    3. Oranges Oranges, like lemons and limes, are citrus fruits with citrate present in them. This has the same benefits as lemon juice and also lowers the acidic level of urine. High acidity in urine is linked with some common types of kidney stones.

    4. Milk Milk is a great source of dietary calcium. While taking calcium through supplements is linked to higher rates of kidney stones, consuming it from food sources like milk is linked to a lower risk.

    5. Legumes and Nuts Legumes and nuts are also great sources of dietary calcium that may help to cut down your risk of kidney stones. When calcium is consumed from food sources like these, it binds with oxalate in the digestive system itself. This means that there is a lower chance for calcium oxalate to form in the kidneys.

    Rethink Some Healthy Foods

    Your doctor may recommend more dietary changes for you based on stone type and the results of a 24-hour urine test to determine your urine composition basically, what your urine is made of.

    If you have high oxalate content in your urine, for instance, your doctor may advise staying away from oxalate-rich foods like rhubarb and spinach. Or they may recommend eating those foods with dairy, as the calcium from milk products binds to oxalates and forces them into your feces rather than urine.

    Oxalate is in a lot of really healthy foods like greens, vegetables, beans and nuts, says Dr. De. So we would only restrict them after examining a patients stone type and urine test results.

    Get Enough Calcium From A Balanced Diet

    If you already have an adequate calcium intake, this may not be helpful to reduce your chances of stones. The amount of calcium you need depends on your age and gender. Check with your primary care provider or urologist on what is right for you. Also, make sure you have vitamin D in your diet to help the body absorb the calcium.

    While you may think it would be helpful, taking calcium supplements does the opposite and may increase the risk. If you need to take supplements, be sure to take them with a meal to try to reduce that increased possibility of stones.

    Best Eating Habit To Prevent Kidney Stones Says New Study

    Kidney stones may be developed due to your eating and drinking habits. According to the National Kidney Foundation, too little water or too much food with sugar, salt, or fructose can cause kidney stones. A lack of calcium may also lead to the most common type of kidney stone, calcium oxalate. Therefore, it’s important to develop eating habits that help minimize your risk of developing kidney stones.

    According to new research published in the Mayo Clinic Proceedings, evidence suggests that diets high in calcium and potassium may help prevent reoccurring symptomatic kidney stones.

    For the research, 411 people with medical records of symptomatic kidney stones were observed from January 1, 2009, to August 31, 2018. They all took a questionnaire that compared what the people were eating in their diet that could risk symptomatic kidney stones.

    The results showed that those who ate less calcium, potassium, caffeine, and phytate in their diet, as well as drinking less, were all associated with higher odds of a symptomatic kidney stone.

    “It is well known that diets rich in calcium and potassium are necessary for adequate health,” sharesAmy Goodson, MS, RD, CSSD, LD, author ofThe Sports Nutrition Playbook. “In fact, these two nutrients are two of the four nutrients of concern for Americans . This means that people don’t consume enough of them and need to eat more.”

    The Best Diet To Help Prevent Kidney Stones

    Its estimated that 1 in 10 people will get a kidney stone in his or her lifetime. Kidney stones are not only painful, but they can lead to serious complications that may require hospitalization and even surgery. The good news is kidney stones are preventable, and prevention can be as simple as eating the right foods.

    The most important thing to think about with kidney stones is prevention, says Dr. Ivan Porter II, a Mayo Clinic nephrologist.

    A solid prevention plan includes thinking about the types of food youre eating. Dr. Porter says fruits and vegetables with high water content, like cucumber, tomato and watermelon, also have natural citrate.

    These things are natural stone inhibitors and can be a part of a stone prevention plan to help prevent further kidney stone formation, says Dr. Porter.

    Its just as important to think about what you shouldnt eat.

    We know that animal sources of protein are simply associated with a higher risk of stones. One way to avoid more stone production is maybe to limit your meat intake to some smaller amount, says Dr. Porter.

    Certain foods, such as spinach and rhubarb that have high oxalate levels, also should be restricted.

    A lot of leafy greens that actually are good for you may have that negative impact on stones. And one way to combat that is by having some dietary calcium with those meals. So cheese on top of that spinach might be a good idea, says Dr. Porter.

    Foods To Avoid With Kidney Stones

    Mayo Clinic Minute: What you can eat to help avoid getting kidney stones

    Did you know that a healthy diet can directly reduce your risk for kidney stones? Nutrition is a critical piece of kidney stone prevention that is often overlooked.

There is a ton of information online that is inaccurate and not based on quality science. This has led to conflicting information and confusion about what a healthy kidney stone diet actually is.

    Keep reading to learn about what the evidenced-based kidney stone diet is and what you can do to prevent calcium oxalate kidney stones!

  • Example Kidney Stone Diet Meals
  • Eat A Moderate Amount Of Protein

    A high protein diet will increase the urine calcium. In addition, high protein diets produce acid during metabolism. This acid is eventually excreted in our urine, which lowers urine pH and increases the risk of kidney stones. Similar to sodium, the extra calcium in urine from a high protein diet is taken from bone, putting them at risk.

    For most people, a healthy amount of protein is: 0.8 grams protein / kilogram body weight. For example, a person who weighs 175 pounds should eat about 64 grams of protein per day . The right amount of protein for you might be different based on your body size, age, sex or nutrition status. Always ask your dietitian what is best for you.

    Similar to sodium, most Americans eat much more protein than we need. The 0.8 grams per kilogram recommendation for people with kidney stones is the same amount recommended for healthy adults. Even for people who are vegetarian or vegan, it is fairly easy to eat enough protein.

    Unsurprisingly, most of the protein in our diet comes from meat, poultry, fish and seafood. A 3 ounce portion of animal flesh has about 25 grams of protein in it. This is 40% of the protein goal for the entire day in our example of a 175 pound person. Pair that with protein from meat eaten at other meals and the small amount of protein found in nearly all foods. You can easily see how protein adds up quickly!

    Diet For People With Calcium

    Oxalates are produced in the body as well as absorbed from the food we eat. Calcium can bind to oxalate and form calcium-oxalate stones, this is one of the most common types of kidney stones. Certain factors may encourage calcium-oxalate stone formation such as low intake of water, excessive amounts of oxalate in the body and urine and high salt levels in your diet. To combat this, you need to:

    • Always eat sufficient amounts of calcium-rich foods with your meals whenever you consume oxalate-rich foods
    • Avoid or limit oxalate-rich foods like spinach, beetroots and carrots
    • Maintain healthy levels of dietary calcium with food sources like milk and dairy products unless suggested otherwise by your doctor
    • Reduce your salt intake since sodium can lead to excess calcium in the urine
    • Talk to your doctor before taking any calcium supplement

    Staying Hydrated Helps Prevent Kidney Stones

    The number one natural way to prevent kidney stones is to drink more water. If you are not hydrated, you will not produce enough urine. This can increase the chances of kidney stones because low urine output means the urine is concentrated and less likely to dissolve urine salts that cause kidney stone.

    I recommend that you drink around eight glasses of water each day. If you sweat a lot, exercise or have a history of stones, you may benefit from additional fluids.

    A good way to tell if you are drinking enough water is to look at the color of your urine

    Orange juice and lemonade are also good options to drink because they contain citrate, which prevents stones from forming.

    Foods To Be Included Or Eat In Daily Diet Plan:

    • Cereals- Rice, Wheat, Maize, Bread, Barley, Jowar, Rice flakes, Puffed Rice, Cornflakes.
    • Pulses and Legumes- Red gram dhal, Black gram dhal, Green gram dhal, Bengal gram dhal, Peas, Soya beans.
    • Fruits and Vegetables- Include Low Potassium and Medium
    • Potassium fruits and vegetables.
    • Non-vegetarian- Egg white, Chicken , Fish .
    • Milk and Milk Products- Milk, Curd & Butter milk .
    • Beverages- Tea, Green tea, barley water.
    • Others- Garlic, Sago, Honey, and Olive oil.

    Lower Your Animal Protein Intake

    Many sources of protein, such as red meat, pork, chicken, poultry, and eggs, increase the amount of uric acid you produce. Eating large amounts of protein also reduces a chemical in urine called citrate. Citrates job is to prevent the formation of kidney stones. Alternatives to animal protein include quinoa, tofu , hummus, chia seeds, and Greek yogurt. Since protein is important for overall health, discuss how much you should eat daily with your doctor.

    Eat Plenty Of Fruits And Vegetables

    I recommend that all people who form kidney stones should have at least five servings of fruits and vegetables daily. This will help by providing fiber, potassium, magnesium, phytate, antioxidants and citrate, all of which can help keep stones from forming.

    If you are worried about knowing how to eat the right amounts of fruits and vegetables, talk to your doctor about what will be best for you.

    It’s Not One And Done

    Passing a kidney stone is often described as one of the most painful experiences a person can have, but unfortunately, it’s not always a one-time event. Studies have shown that having even one stone greatly increases your chances of having another. “Most people will want to do anything they can to ensure it doesn’t happen again,” said Dr. Jhagroo. “Unfortunately, it doesn’t seem to be the case that people make the changes they need to after their first stone event.”

    Research conducted by Dr. Jhagroo shows that those with kidney stones do not always heed the advice of their nephrologists and urinary specialists. About 15% of kidney stone patients didn’t take prescribed medications and 41% did not follow the nutritional advice that would keep stones from recurring. Without the right medications and diet adjustments, stones can come back, and recurring kidney stones also could be an indicator of other problems, including kidney disease.
