Why do some people recoil at Brussels sprouts, black coffee, and hoppy IPAs while others love them? This episode explores supertasters, people who experience certain flavors, especially bitterness, far more intensely than average, and shows that the difference is anatomical, not attitude.
We trace the story from Arthur Fox's accidental 1931 discovery with PTC dust at a DuPont lab to Linda Bartoshuk's research on PROP and the 25-50-25 split between non-tasters, medium tasters, and supertasters. Along the way we cover the TAS2R38 gene, fungiform papillae, the health trade-offs of the trait, and the evolutionary logic behind a hypersensitive tongue.
- How a 1931 lab mishap revealed that people taste the same chemical very differently
- The blue food dye test that makes fungiform papillae visible on your own tongue
- Why the TAS2R38 bitter gene alone cannot explain heightened reactions to sweetness, fat, and carbonation
- Health effects linked to supertasting, from lower BMI and less smoking to a higher colon cancer risk
- How bitter sensitivity may have protected early humans from toxic plants
