My recent interviews and talks about low-oxalate eating present important information that you’ll want to see and hear. In addition to the talks below, you can find more audio and video resources on the Results page and on my YouTube channel.
This page is organized by broad topics
The talks and interviews in this section will give you a solid grounding in the science and practice of low-oxalate eating.
2017 Ancestral Health Symposium
This is the talk that got the keto and carnivore world talking about oxalates. I presented the potential problems stemming from the combination of lack of awareness of oxalates in foods and the promotion of superfoods, many of which are high in oxalate. When we encourage people to eat high-oxalate foods daily, we are putting them at risk for oxalate toxicity. As a result, we may be setting ourselves up for a public health crisis. A receptive audience in Seattle, Washington, heard this talk at the 2017 Ancestral Health Symposium. Don’t forget to read my companion article on lost seasonality, available here for free.
The Hidden Dangers of Oxalates in Your Foods (March 2019)
Elliot Overton and Doug DiPasquale interviewed me in March 2019 for their Objective: Health videocast series (published April 7, 2019). Elliot has taken a great interest in oxalates himself (smart man!), and he has also been spreading the word about oxalate dangers. It was a great delight to talk with Elliot and Doug, and to answer their excellent thoughtful questions. We focused on debunking many myths about healthy foods and about oxalates. The interview covers the basics but also touches on some of the trickier points of transitioning to low oxalate eating. You can view the full interview right here:

Peak Human: On Oxalates, Plants Hurting your Health, and Never Eating Spinach Again (April 2019) [Audio Only]
I also enjoyed talking with Brian Sanders, who is producing the film
If you like what you hear on Brian’s podcast series, don’t forget to support the Food Lies film and the Peak Human podcast series through Indiegogo or Patreon. Brian’s quest to understand the truth about nutrition and the effect of the foods we eat on our health is very important.
“Why Eating Plants can Ruin Your Health” with Paola Dziwetzki (April 2019)
Paola Dziwetzki (“The Power of Ozone”) and I talked about the health effects of oxalates, the many health issues they can cause, and the challenge of recovering one’s health. Watch here on YouTube:
Presentation Recording: Become Oxalate Savvy for Better Health (November 2018)
I presented a lecture, Become Oxalate Savvy for Better Health, to an enthusiastic crowd at the annual Wise Traditions Conference in Baltimore MD on November 18, 2018. This MP4 file consists of the audio recording of my remarks paired with the video display of my slides. The slides are filled with images that tell the story of oxalates and why they are a problem.

Dr. Ruscio Radio (9/2017) [Audio Only]
Dr. Michael Ruscio, a gut health expert who publishes an excellent podcast series, had some questions about oxalates and their role in chronic health problems. I explained the answers in the episode released on September 20, 2017. Go to Dr. Ruscio’s podcast of our talk for a full transcript and additional resources. Listen here:
Even though these interviews embrace a carnivore (all-meat diet) perspective, they contain a lot of useful information regardless of what you’re currently putting on your favorite plate of food. Plus they’re all really fun talks!
Nutrition with Judy: Superfoods that will harm you (August 2019)
CarnivoreCast: Oxalates, the hidden toxin in many Keto foods (September 2019)
Scott Myslinski (CarnivoreCast) and I took a tour through the inadvertent risks of oxalate toxicity when practicing a Keto diet, and how it can come back to haunt you when you go carnivore and your body starts to unload the accumulated oxalate. Audio here:
Carnivore Eating and Low-Oxalates for Free Diving Performance (May 2019)
Renee Blundon is a champion freediver and coach who is breaking new ground by going “carnivore” even as many in her sport hold on to the idea that vegetables are king. Her own performance has gone up since she took on a meat-based diet, and she wondered whether reduced oxalate was playing a role. She got in touch with me, and we took a “deep dive” together to sort it all out (sorry, couldn’t resist!). We had a great conversation about the benefits that getting oxalates out of your diet can have on elite athletic performance.
Human Performance Outliers with Shawn Baker and Zach Bitter
I had the pleasure of talking for a couple of hours with Shawn Baker and Zach Bitter on their Human Performance Outliers podcast. Shawn is a popular resource in the carnivore community, and he and Zach are very interested in the dangers of oxalates, both as people eat them and also after we stop eating them up and our bodies start to move them out. We talked about oxalates, healthy diets, and food policy. Our discussion came out in two episodes.
Attack of the Oxalates! A hidden but nasty plant toxin (April 2019)
Paul Saladino MD and I went “nose to tail” on the many ways in which oxalates put our health at risk. We covered a lot of the basics, and did a scientific “reality check” on the mechanisms and effects of oxalates. Paul also observed symptoms in himself after giving up foods with oxalates (you’ll learn about my simple remedy for eye sties). Paul added some time points for the key topics that you can find on the YouTube page for the video, or you can watch the whole thing here:
Primal Edge on Oxalates: Are Vegetables Really Healthy? (April 2019)
My fun conversation with Tristan Haggard on his Primal Edge video series considers the implications of oxalate for the keto and carnivore world. We reviewed the perils of vegetables, and the delayed effects that a long history of high-oxalate eating can lead to when you cut oxalates in your diet. If you’re considering a ketogenic or all-meat diet, and especially if you’re trying to reverse accumulating damage from, you’ll learn a lot from this interview.
Low-Carb and Keto Eating
Keto Connect (June 2019)
I talked with Keto Connect and we focused on the oxalate connection to kidney health, and the likelihood of becoming an oxalate accumulator when the kidneys are damaged or struggling. Co-host Megha Barot realizes that her spinach smoothies and snack foods are contributing to her serious kidney stone problem. I also shared the story of a woman who went into metabolic crisis after 18 months of Keto and an abrupt shift to a low oxalate diet. It’s time to learn to implement a low oxalate diet and use supportive therapies for safe reversal of oxalate overload and better kidney function!
My Sugar Free Journey (May 2019)
Here’s a chat I had about oxalates with Aarn Farmer for his podcast My Sugar Free Journey. Aarn lost over 200 pounds by cutting sugar from his diet! But any major diet shift that includes adding in or cutting out a lot of vegetables runs the risk of oxalate toxicity. Two formats available below (audio and YouTube).
Livin’ La Vida Low Carb, with Jimmy Moore (July 2018)
I talked with Jimmy Moore on his “Livin’ La Vida Low Carb” podcast about the benefits of low-oxalate eating, and some of the challenges that low-carb eaters can face when they start adding in high-oxalate foods such as nuts, spinach and swiss chard. We also talk about the “keto rash” and the unexpected symptoms that may arise when someone going low-carb suddenly and unknowingly zeroes out their oxalate intake. You can go to the podcast episode home page, or listen directly here:
Keto Carole (9/2017)
Keto Carole produces a video podcast focused on low-carb eating. She is especially concerned about “how we’ve been ‘brainwashed’ to think that plants are so healthful and the more plant foods we get the better, so you should try to eat tons of them and juice them and eat giant salads.” After she heard my talk at the Ancestral Health Symposium, Carole and I sat down to explore hidden natural toxins such as oxalates in plants and how some plants are not the superfoods that we’re being told they are. This podcast episode was released on September 27, 2017. You can also find a transcript of our talk on Carole’s site. View here:
Get Fit with Jodelle (July 2018)
Jodelle Fitzwater runs a great podcast Get Fit with Jodelle. I talked with her in the July 21, 2018 episode, which Jodelle introduced like this: “Could the so called superfoods of today actually be harming you? Why did Paleo come about and then several years later we needed Auto Immune Paleo? Do you eat cleaner than anyone you know and yet you have more issues than anyone you know? What is the Keto Rash and why does it happen? And why aren’t you seeing the results you want on a ketogenic diet. The truth is, many of today’s trendy superfoods such as those killer green smoothes, and sweet potato fries could actually be slowing killing you! And while nutrition isn’t the end-all-be-all with regard to optimal health, you should know that certain foods contain toxins called oxalates that could be the reason you are suffering.”
