You cut out spinach and almonds completely, but your urine tests still show high oxalate. It is deeply frustrating when you work hard and still make kidney stones. We walk you through why your oxalate stays high even on a healthy diet.

We explain how calcium acts like a magnet for oxalate inside your body. When you eat half a sweet potato with cottage cheese, the calcium binds to the oxalate. Your body flushes them both out in your stool. Without enough calcium, that extra oxalate passes straight into your blood. We also look at how stomach issues or fat absorption problems break this process apart.

We also cover how taking extra vitamin C supplements can secretly raise your oxalate levels. You will walk away knowing exactly what your urine test numbers mean. You will get clear, actionable steps to balance your meals and protect your health.

WHO IS JILL HARRIS? _
Since 1998, Jill Harris has been the #1 kidney stone prevention nurse helping patients prevent kidney stones. Drawing from her work with world-renowned University of Chicago nephrologist, Dr. Fred Coe, and the thousands of patients she's worked with directly, she created the Kidney Stone Diet®. With a simple, self-guided online video course, meal plans, cookbooks, group consultations, and private consultations, Kidney Stone Diet® is Jill's effort to help as many patients as possible prevent kidney stones for good.

Up to 60 percent of calcium kidney stone formers have too much calcium in their urine. You will never know this is happening without a 24-hour urine test. We walk you through the top five reasons your body leaks extra calcium into your urine. We also share what you can do to stop it.

High urine calcium often comes from eating too much salt or too much meat protein. Taking high doses of vitamin D can also cause it. Sometimes, small glands in your neck pull calcium straight out of your bones. That extra calcium dumps into your kidneys, creating stones and leaving your bones weak.

We show you how to spot these causes and talk to your doctor. You will learn simple food changes, like eating less sodium, that keep calcium where it belongs. We help you protect your kidneys and keep your bones strong.

Too many doctors tell patients they are just kidney stone formers. They say nothing can be done. That is simply not true. There is always a reason why your body makes stones. We explain why surgeons often miss prevention steps.

We talk about the single most important test you need: a 24-hour urine collection. You will learn what to say if your doctor refuses to order it. We also cover other health workers who can order this lab test for you.

You do not have to live with stones for decades or risk losing a kidney. The right treatment plan can lower your stone risk by up to 80 percent. You will walk away ready to get real answers based on your actual lab results.

Kathleen asks whether her daily hibiscus tea—which she drinks to help manage blood pressure—could be putting her at risk for kidney stones. Jill breaks down what really matters with any tea: how much you're drinking, how long you steep it, and why oxalate levels can climb the longer a tea bag sits in hot water. She also shares a simple way to test any food or drink against your own 24-hour urine collection to see its real effect on your oxalate levels.

"Drink lemon water" is the #1 piece of advice kidney stone patients hear from their doctors. But is it actually helping you? In this episode, Jill Harris breaks down why this generic advice can be useless (or even make things worse) when it's not based on your actual results.

Jill shares a real patient story: someone who made stones for 20 years, faithfully drank lemon water the whole time, and only discovered through a 24-hour urine collection that lemons were never what she needed. In her case, they were slightly raising her risk of calcium phosphate stones.

Kidney stone patients are cutting way too many foods out of their diet, and it's making their world smaller and joyless. In this episode, Jill breaks down why "high oxalate" doesn't mean "forbidden," using real numbers from the Harvard Oxalate Food List to show that foods like sweet potatoes, kale, avocados, peanut butter, and blueberries can absolutely fit into a low-oxalate lifestyle in the right portions.

She walks through her own coaching calls, explains how to use the free oxalate calculator and food list tool at kidneystonediet.com, and shares why building a daily oxalate "budget" (rather than banning foods outright) is the key to long-term compliance, real joy, and better stone prevention.
