Coming Winter 2021

Oxalates are highly reactive molecules found in certain foods and made by our bodies when under metabolic stress. They create pain, oxidative stress, inflammation, and many other symptoms in the body, and they can cause or exacerbate chronic illness. More and more people are realizing that oxalates are a root cause of their health concerns, and discovering there are helpful approaches to safely reduce oxalate levels and resolve symptoms.

Oxalate is a relatively new nutritional challenge. In past generations oxalate was successfully degraded by a complex microbiome, The composition of the microbiome has been altered in the last 70 years by antimicrobial medications and also by stresses like illness that may deplete critical vitamins. Those changes have meant that we may not be able to eat the same foods that our ancestors ate. Whether you are an individual wanting to understand and address oxalates for yourself or a practitioner helping others navigate a low oxalate diet, this summit will provide the resources and educational tools you need from the thought leaders in the field.

Susan Owens

Susan Costen Owens, MAIS, has spent the last 25 years conducting research looking at the biochemical issues in autism and in other disorders where oxalate is elevated including autoimmune conditions. She has conducted a study with a team in Poland highlighting the frequency of oxalate issues in autism in 2011. Most clinical studies where oxalate is elevated fail to realize the toxicity of oxalate to the immune system, to the gut and its microbiome, and to mitochondrial function. Clarifying these scientific issues has been her main focus, as well as exploring the genetic side. She is a patient advocate at the Mountain States Regional Genetics Network, and has lectured around the world on sulfate and oxalate roles in biology. Susan is a graduate of Vanderbilt University, and completed her Masters degree in Interdisciplinary Studies at the University of Texas at Dallas. Her online groups and website have helped more than 30,000 people explore the benefits of reducing oxalate. Visit
