A high carbohydrate diet of rice, plantain, manioc and corn, with a small amount of wild game and fish – plus around six hours’ exercise every day – has given the Tsimané people of the Bolivian Amazon the healthiest hearts in the world.
It may not be a life that everyone would choose. The Tsimané live in thatched huts with no electricity or modern conveniences. Their lives are spent on hunts that can last for over eight hours covering 18km for wild deer, monkeys or tapir and clearing large areas of primal forest with an axe, as well as the gentler pastime of gathering berries.
But as a result of this pre-industrial lifestyle, the Tsimané have hardly any hardening of the arteries. Heart attacks and strokes, the biggest killers in the US and Europe, are almost unknown.
