Episode notes
Tsimané Have Nearly Perfect Coronary Arteries
- The Tsimané (Chimane) show almost no coronary artery calcification in 90% of adults 40+ despite high inflammation levels.
- Michael Gurven measured coronary CTs directly, proving population-level absence of calcified plaque as opposed to just low risk factors.
Avoid Processed Foods To Curb Overeating
- Avoid processed foods and soda to reduce overeating and excess calories that brain cues don't register properly.
- Gurven emphasizes eliminating processed items as the single actionable dietary change drawn from Tsimané habits.
Cheeseburger Given Away As Instant Food Sharing
- Gurven bought an Asunción cheeseburger for an Ache boy who immediately gave it away to a hungry stranger.
- This example illustrates the strong food-sharing norm: people give surplus food to those who appear hungry even without guaranteed reciprocity.
