How Your Healthy Diet Caused Your Kidney Stones

Most of my patients come to me saying…

“I finally started eating healthy, I lost 63 pounds, and then I got a stone.”

Now what?

It can be very frustrating to realize your “healthy” diet is the reason you made a kidney stone. I often find my job as a kidney stone prevention educator consists of helping people bring healthy foods back into their diet in a safe and enjoyable way.

What Can I Eat?

Patients are overwhelmed and scared by the time they find me. Once they learn that healthy plant foods have caused their stones, they cut out all fruits and veggies. Many patients tell me they have nothing to eat. Well I am here to tell you– you have plenty to eat.

What is the best Oxalate List?

Dr. Coe and I rely on the Harvard oxalate list as a source because it has worked for our patients for many years. However, you need to know HOW to use the list to effectively in order to lower the quantity of high oxalate food you eat. It can be quite challenging to do this and simultaneously incorporate all the other advice we give you.

Portion Size Is Key

Even with healthy foods we need to watch our portions. Just because almonds are the latest healthy food, that doesn’t mean we should be eating them all day long. I can’t tell you how many of my male clients say, “I was just eating a few handfuls here and there”. Guys, look at the size of your hands. They can hold a ton of almonds. And all those almonds happen to be very high in oxalate.

Ladies, how much spinach are you putting in your salads? Spinach might be called a superfood but that doesn’t mean eating 7 cups a day of spinach is super for you.

If you really watch your portion size on higher oxalate foods, you can bring some of those foods back into your diet. I do recommend patients eliminate spinach and substitute kale because spinach is just too high in oxalate. I also tell patients to substitute pistachio nuts and sunflower seeds for almonds, another high oxalate food. Even with lower oxalate substitutions, it is important to watch portions on these lower oxalate nuts. If you come to my classes, you will learn all about the portions that are right for you.

Eat Healthy Without Raising Your Oxalate

You can keep eating healthy. You just need to learn how to do incorporate fruits and veggies into your diet without raising your oxalate levels. This is why Dr. Coe and I started The Kidney Stone Prevention Course. In the course, you will learn how to bring back your favorite healthy foods – without increasing your oxalate level. I have had patients with oxalate levels well over 100. After they took the course, they lowered their oxalate levels into the 20’s. Read how a private client of mine lowered her oxalate from the 120’s to 29. Her vegan lifestyle brought about her stones, but with careful planning she has maintained her vegan diet and lowered her oxalate. She did it and you can too!

When you’re ready, here’s how I can help you prevent kidney stones

Since 1998, I’ve helped thousands of patients prevent kidney stones. With my Kidney Stone Diet All-Access Pass, you get access to every prevention tool I’ve ever created:

      Dear Judy,
      You definitely DO NOT need to give up plant foods. There are so many plant options for stone formers to eat. I truly don’t recommend that for anybody trying to put together a healthy diet. Read this:https://kidneystonediet.com/did-your-healthy-diet-cause-your-kidney-stone/

      Hi Donna,
      The course is an excellent value- you get gain lifetime access to nearly 5 hours of stone prevention education through video and then also get to come to my group q and a calls for a month- five times per week.
      Hope that helps-

    Is the Harvard oxalate list in print? I would rather have it easily in my hands than try and find it on line every time I want to see it.
    Thanks

    Hi Jill
    Lately, the Mayo
    Clinic did a study which showed that there is no proof that diet is connected with recurring kidney stones. But more drinking a lot of water. Intake calcium, etc. And I think portions, too.
    This seems to be contrary to Harvard. Where do you stand on this latest finding. (I am truly confused.)
    Looking forward to your response.
    Thank you.

      Hi Donna,
      Sure would like to see that study. I will look for it. Here is what I can tell you, I have been helping patients reduce their stone risk for 23 years. The diet works. If Mayo is talking about portions, calcium, and water, they are talking about diet. But they must be talking about salt and sugar, too as these two things definitely increase urine calcium.

    Spinach and almonds must have done me in. For 4 years I consistently ate a huge spinach salad topped with slivered almonds, oranges, and grilled chicken at least 3 times a week at work. I was serious about losing weight. Well I lost about 150 pounds during that time, so it worked! I traded body fat for kidney stones! I have given up the spinach and almonds completely and have continued to lose 45 more pounds following your daily goals (plus a few of my own). Thank you for your dietary guidance. I was very overwhelmed in the beginning, but it all make sense now.

    If my 24-hour shows low oxalate BUT my urinary calcium is high, should I still consider a low oxalate diet? In particular, I eat a lot of spinach and am wondering if I should stop…

      Hi Beth,
      Yes, you should stop eating spinach. The report shows levels for what you ate and drank during that 24 hour period. If you have high urine calcium follow the kidney stone diet. Lowering salt and added sugar will help keep that calcium in your bones where it belongs and out of your urine.

    hello jill, the lab analyzed my stones and they are made up of calcium oxalate monohydrate. These are the common ones, no? Any particularities regarding a diet or a low oxalate diet will help? thanks. Marc, in Québec

    Hi Jill. I may be a bit different than some of your patients. I am not a vegan or vegetarian, but have had stones for 50 years, 2 operations in my 20s and have passed an easy 100 stones. I am frustrated because I am just now learning from you about oxalate as the problem when none of my past Doctors has ever mentioned this. I currently have 12 stones inside me and I have been taking potassium citrate to control or stop the formation, so much for the success of that, but my question is what should be the correct mixture of calcium and oxalate that will stop these flippin things. I will be taking a 24hr here soon but at 72 years old this crap is getting old. any help would be appreciated.

      Hi Jack,
      You will find this video from my YouTube channel helpful. And yes, you must get a urine collection to see WHY you are forming stones. Obviously the pot citrate is not cutting it. There are other reasons.

    Dr. Harris,
    I have the highest praise for you. After 21 years of kidney stones and lithotripsy procedures, which worsened my condition through fragments of stones lodged in other parts of my kidney and growing, I was introduced to your website and oxalate food list by my GI surgeon. It has provided more of an understanding of food consumption and high oxalate levels. I look forward to your newsletters and emails. Kudos to you!

“The Kidney Stone Diet is far more than just a diet; this plan is life-altering!”

“The group calls will transform you physically and emotionally. Once you start this journey, your health naturally improves. I have lost a total of 40 pounds and have consistently kept it off. The group calls are such support; this is more like family than a zoom meeting to stay accountable. Jill is far more than a nurse; she is a life coach. Her platform is invaluable.”

Kim J. | Kidney Stone Prevention Course

“The best decision I’ve made has been to join this group.”

“I have been working on weight loss for many years. This group has kept me on track and has helped my continued success with my weight loss.”

Kate L. | Group Calls with Jill

“I have been following the Meal Plan for about 6 weeks and I feel amazing.”

“Eating healthy has also encouraged me to go to bed earlier, so I am also getting more sleep. Because of that, I have been able to get up before work and exercise! So yes, the positive effects are spilling over into all areas of a healthy lifestyle.”

Jerry T. | Meal Plan Subscriber

“I have been a part of the group calls with Jill for the last 14 months, and they are essential to being so successful with the Kidney Stone Diet Prevention Plan.”

Sarah B. | Group Calls with Jill

“These calls are the gold of this program!!”

“I can’t say enough about how Jill knows just the right questions to ask us or how she prods us to think about what is going on in our lives.”

Monica K. | Group Calls with Jill

“I took the course with Jill, and my second 24 hour urine was MUCH better than the first.”

“She gives very practical information, and it WORKS. I was totally overwhelmed at first. I got very poor diet information from my doctors. Jill made it easy for me to understand, and I took it one day at a time. I still watch her videos when I need a tune-up. Jill is the best, and she really cares about all of us. Take the course—it will help you!!!”
