P.S. You’re showing up every day for others—a reminder: you deserve snacks that show up for you, too.

P.P.S. All the teachers I work with are dehydrated because they cannot use the bathroom. Ask your doctor to provide a note stating that using the bathroom is a medical necessity. Either that, or the school will be scrambling to call in substitutes on the day you have your next lithotripsy.

    I was told I could not have any nuts or nut butter as in peanut butter, but you have it on your list for snacks. I was also told that carrots were a no no as were most other vegetables except for peas. I have printed out your list of foods and their oxalate count which has really helped me stick to and acceptable diet. thank you

      Hi Elisabeth,
      You know the reason I chose those particular foods? Because many people think they can’t have them anymore and it just isn’t true. Make sure you look at the Harvard list. You get 100 mg/ox/day. Use your budget however you want and for the higher foods like peanut butter, pair it with a calcium source. Promise you will be just fine. Don’t forget to look at my YouTube channel and this blog for all things oxalate and kidney stone prevention.

    Hi Jill,
    Thanks for your good list.
    I like the idea of thinking of a 100 mg/ox/day budget, rather than going to extremes about avoidance.

    My discovery over the last few years is the importance of lutein and zeaxanthin for eyes. The maculas in our eyes accumulate these from the foods we ingest and lower the risk of macular degeneration. Unfortunately, a lot are high oxalate foods. So, egg yolks are both no oxalate and highly bioavailable L&Z and I can combine some of the others with dairy calcium.

“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!!!”
