Sally K Norton, MPH

Sally Norton holds a BS in nutritional science from Cornell University and a Master of Public Health from the University of North Carolina at Chapel Hill, where she managed a five-year NIH-funded program at the UNC School of Medicine on integrative healing practices. She is the most rigorous public researcher on dietary oxalates. Her 2023 book "Toxic Superfoods" (Rodale) makes the case that oxalates in commonly recommended healthy plant foods — spinach, almonds, sweet potato — drive a range of poorly diagnosed chronic symptoms.

Norton is not a carnivore advocate per se, but her work is the most cited research on a specific class of plant compounds that many carnivore practitioners eliminate. Her oxalate-dumping framework also explains a common pattern of symptoms during the first weeks of the dietary transition.
