Welcome to the 44th episode of the Back to Human Podcast!

On this episode, I had the pleasure of interviewing Sally K. Norton, MPH, author of Toxic Superfoods. After years of consuming so-called "healthy" foods, Sally suffered from chronic pain, fatigue, and unexplained health issues—until she discovered the hidden dangers of oxalates. Her journey led her to uncover how these naturally occurring compounds, found in many popular foods, can silently contribute to serious health problems.

Despite being promoted as “superfoods,” many plant-based staples contain high levels of oxalates—compounds that can accumulate in the body and trigger a range of issues, from joint pain and kidney stones to inflammation and mineral depletion. In this episode, Sally breaks down the science behind oxalates, the symptoms of toxicity, and what you can do to protect your health.

• Sally’s personal health struggles and how she uncovered oxalate toxicity
• What oxalates are and where they come from
• Commonly promoted “superfoods” that are high in oxalates

• Why high oxalates in urine signal deeper issues

• Do we really need fiber? A look at common misconceptions

• How cultural norms, dietary trends, and societal conditioning shape our beliefs about "healthy" foods
