Claim summary · not a verbatim quotation
After the introduction of sugarcane, almost 100% of the Pirahã population developed cavities.
The finding
What the evidence shows
It's well documented in dental research that introducing high sugar foods to a population that didn't have them before causes cavity rates to climb fast. But a flat 100% cavity rate is an extreme, absolute number, and we couldn't find any actual clinical or dental survey of the Pirahã to support that specific figure, so the real increase is likely dramatic without necessarily being universal.
