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

author avatar Dr. Eric Berg 11/19/2024

Dealing with kidney stones can be painful. If you’ve had them, you’re likely seeking ways to prevent future ones.

Dietary changes, like understanding oxalates and reducing oxalate intake, often help. Many people enjoy nuts, but could some nuts contribute to kidney stone issues?

This leads us to low oxalate nuts. Let’s explore what you need to know about oxalates and which nuts are your best choices for maintaining healthy oxalate levels.

Understanding Oxalates and Kidney Stones

Kidney stones are hard deposits that form in your kidneys. The most common type is calcium oxalate stones.

Limiting oxalate fruits and other high-oxalate foods can be important if you're prone to these stones.

Keep in mind that not everyone reacts to oxalates the same way. Individual oxalate levels can vary.

However, not everyone processes oxalates the same way. Genetics, hydration levels, and overall diet can affect how the body handles oxalates.

While some people can tolerate moderate oxalate levels, others may need to adhere strictly to a low-oxalate diet to prevent stones.

Understanding which foods are high in oxalates—including certain nuts—is a vital first step toward dietary management.

Why Are Some Nuts High in Oxalates?

Almonds, for example, have various health benefits. However, they are a higher oxalate food and could cause issues for someone on a low-oxalate diet.

Cashews, peanuts, and sunflower seeds also tend to have higher oxalate levels, especially when eaten in larger amounts. Those on oxalate diets will want to limit these.

Navigating the World of Low Oxalate Nuts

So, what are the best low-oxalate nuts? Macadamia nuts, pecans, and pistachios top the list for those following a low-oxalate diet.

Macadamia Nuts: The Low-Oxalate Champion

Macadamia nuts are versatile, offering a rich, buttery flavor. Enjoy them as a snack, or add them to salads and low-oxalate desserts.

Macadamias are perfect for those seeking flavorful low oxalate nuts and looking for oxalate diets.

Pecans: A Southern Comfort Food, Low in Oxalates

Pecans offer that Southern charm. With their subtle sweetness, they’re delicious in baked goods. They also make a great addition to trail mix with other low-oxalate nuts.

Pistachios: More Than Just a Pretty Snack

These green nuts bring flavor and are full of fiber and antioxidants. Pistachios make an interesting addition to dishes.

If you crave a salty, savory snack, buy pistachios in their shells to keep portions reasonable. The added effort can reduce overeating, preventing kidney stones.

Making Low Oxalate Nuts Work for You

Centering snacks or recipes around low oxalate nuts can change your view of this dietary change.

Tips for Incorporating Low Oxalate Nuts

Don’t just snack on them (unless that's your preference). Add pistachios or pecans to a salad with low-oxalate leafy greens for crunch. Try macadamia nut butter or make your own with macadamia nuts.

What About Nut Butters?

Be careful with nut butters, even when choosing a low-oxalate nut. Commercial nut butters sometimes contain oxalates from added ingredients.

So be mindful of oxalate content even in foods that seem low-oxalate.

The Importance of a Balanced Approach

If you’re watching your oxalate intake, limiting portions is crucial. Make sure you understand oxalates before changing your diet.

Combining Nuts with Calcium-Rich Foods

Try consuming low oxalate nuts with calcium. Eat cheese or drink milk with them. The calcium binds to oxalates in your digestive system for elimination.

This helps reduce oxalate levels and prevent calcium oxalate kidney stones.

Staying Hydrated is Essential

Staying hydrated, particularly drinking water, is vital for preventing kidney stones. This helps flush out potential crystals. Staying hydrated should be part of a good health approach.

Choosing Kidney-Friendly Nuts on a Low Oxalate Diet

Pecans are a fantastic choice, as they are naturally low in oxalates and fit well within a variety of dietary plans, including keto.

To make them even more enjoyable, you can prepare keto candied pecans, offering a delicious snack option that aligns with both low-oxalate and keto-friendly guidelines.

By focusing on nuts like pecans and ensuring they are prepared with low-carb, natural sweeteners, you can support kidney health without compromising on flavor or dietary goals.

These choices make it easier to maintain a proper, satisfying diet while reducing potential kidney stress.
