How To Avoid Kidney Stones

What Nuts Have the Lowest Amounts of Oxalates to Minimize Kidney Stones?

Here are the five ways to help prevent kidney stones:

Drink plenty of water: Drinking extra water dilutes the substances in urine that lead to stones. Strive to drink enough fluids to pass 2 liters of urine a day, which is roughly eight standard 8-ounce cups. It may help to include some citrus beverages, like lemonade and orange juice. The citrate in these beverages helps block stone formation.

Eat calcium rich foods: Dietary calcium binds to oxalate in your intestines and thereby decreases the amount of oxalate that gets absorbed into the bloodstream and then excreted by the kidney. This lowers the concentration of oxalate in the urine, so there is less chance it can bind to urinary calcium. That leads to decreased risk of kidney stones.

Reduce sodium: A high-sodium diet can trigger kidney stones because it increases the amount of calcium in your urine. So, a low-sodium diet is recommended for the stone prone. Current guidelines suggest limiting total daily sodium intake to 2,300 mg. If sodium has contributed to kidney stones in the past, try to reduce your daily intake to 1,500 mg. This will also be good for your blood pressure and heart.

Avoid stone-forming foods: Beets, chocolate, spinach, rhubarb, tea, and most nuts are rich in oxalate, which can contribute to kidney stones. If you suffer from stones, your doctor may advise you to avoid these foods or to consume them in smaller amounts.

Four Main Kinds Of Kidney Stones

There are four main kinds of kidney stones:

  • Calcium oxalate stones, by far the most common type of kidney stone

  • Calcium phosphate stones, also very common

  • Uric acid stones, often associated with diabetes

  • Struvite stones, often caused by an active infection

The two most common kidney stones include calcium’ in their names, so does that mean you should cut out milk and other calcium-rich foods?

Don’t Underestimate Your Sweat

Saunas, hot yoga and heavy exercise may be good for your health, but they also may lead to kidney stones. Why? Loss of water through sweating – whether due to these activities or just the heat of summerleads to less urine production. The more you sweat, the less you urinate, which allows for stone-causing minerals to settle and bond in the kidneys and urinary tract.

One of the best measures you can take to avoid kidney stones is to drink plenty of water, leading you to urinate a lot. So, be sure to keep well hydrated, especially when engaging in exercise or activities that cause a lot of sweating.

    Kidney stones in the urinary tract are formed in several ways. Calcium can combine with chemicals, such as oxalate or phosphorous, in the urine. This can happen if these substances become so concentrated that they solidify. Kidney stones can also be caused by a buildup of uric acid. Uric acid buildup is caused by the metabolism of protein. Your urinary tract wasnt designed to expel solid matter, so its no surprise that kidney stones are very painful to pass. Luckily, they can usually be avoided through diet.

    Why You Should Avoid Oxalates

    Your body naturally gets rid of oxalates, but in high amounts, they can have adverse effects. However, since foods containing oxalates are often nutritious in other ways, you shouldnt remove them from your diet altogether.

    Most people get between 200 and 300 milligrams of oxalates daily. If youre at risk for kidney stones, sources suggest consuming less than 100 milligrams a day. Doctors may also recommend low-oxalate diets of less than 50 milligrams daily for some people. Talk to your doctor about what diet is best for your health.

    A diet high in oxalates may have some negative effects, including:

    Increased Risk of Kidney Stones

    Estimates show that 1 in 10 people are affected by kidney stones, though some people are at more risk than others. When oxalate levels are high, theres a greater chance it will bind to calcium, forming kidney stones.

    Lower Mineral Absorption

    Because oxalates bind to minerals like calcium, they can prevent your body from absorbing beneficial nutrients in your digestive tract . Yet, they dont block absorption completely, and our bodies only use a portion of the nutrients we consume.

    Antibiotic Interactions

    Some of the oxalates you consume are broken down in your gut, reducing the amount that passes through your digestive and urinary systems. However, when you take antibiotics, this effect is reduced. Antibiotics decrease the good bacteria in our gut that absorb oxalates, which can enhance their activity.

    Diet Tips to Prevent Calcium Oxalate Kidney Stones

    If you happen to be particularly susceptible to calcium oxalate stones, it may be a good idea to reduce your oxalate intake.

    However, there is a downside to this dietary recommendation that is often overlooked. Many high-oxalate foods are also rich in fiber, magnesium, potassium, and phytate, all of which inhibit the occurrence of kidney stones.

    Thus, instead of avoiding such healthful sources of nutrients altogether, try to consume them in moderation.

    Besides, some people are naturally better at absorbing oxalates than others, and thus such oxalate restrictive diets do not apply uniformly to all.

    People with unfavorably high oxalate levels can naturally bring down the amount of oxalate absorption by consuming a high-calcium diet.

    If your urine oxalate level continues to be high regardless, ask a dietitian or other health care professional about how strictly you need to avoid oxalate-containing foods.

    All in all, eliminating oxalate-rich foods from your diet alone will not prevent calcium oxalate kidney stones from forming and will only give you a false sense of security.

    Research suggests that the best way to curb stone formation is to pair high calcium foods with oxalate-rich ones during a meal. This allows the two to bind together in the stomach and intestines before the kidneys begin processing them, making it less likely that kidney stones will form.

    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.

    Calcium Is Not The Enemy

    But it tends to get a bad rap! Most likely due to its name and composition, many are under the impression that calcium is the main culprit in calcium-oxalate stones. “I still see patients who wonder why they are getting recurring stones despite cutting down on their calcium intake,” said Dr. Jhagroo. “I’ve even had patients say that their doctors told them to reduce their calcium intake.” A diet low in calcium actually increases one’s risk of developing kidney stones.

    Don’t reduce the calcium. Work to cut back on the sodium in your diet and to pair calcium-rich foods with oxalate-rich foods.

    Walnuts are in the second group, so theyre not completely restricted on this diet. However, walnuts are also high in fat, and its easy to overindulge on them. So make sure to control how much walnuts you consume even if youre not following a low-oxalate diet.

    If you have had a stone, it is important to keep a check to avoid stone development in the future.
