Joe Rogan Experience #2547 - Daniel Everett · Aired Aug 27, 2026
Claim summary · not a verbatim quotation
The Pirahã people traditionally did not have cavities in their teeth before the introduction of sugarcane to their diet.
The finding
What the evidence shows
This fits a real, well established pattern in dental research: cavity rates are strongly tied to sugar intake, and populations with traditional low sugar diets are well documented to have very low cavity rates. That's a solid general trend, but we couldn't find Pirahã specific dental records confirming they had zero cavities before sugarcane arrived, so stating it as an established fact about this one group goes further than what's actually verified.
