Scott takes on a study published in The Lancet in April 17, Kaplan H, et al. “Coronary atherosclerosis in indigenous South American Tsimane: a cross-sectional cohort study.”
The Tsimane Tribe: The Healthiest Hearts in the World
- The Tsimane lead a holistic healthy lifestyle.
- The study finds that coronary artery disease can be avoided in most people through a lifetime of very low LDL, low BP, low glucose, normal BMI, not smoking, and lots of physical activity.
- The Tsimane are a true hunter-gatherer culture. They hunt, fish and farm on the Maniqui River in the Amazon rainforest in the Bolivian lowlands. Researchers admit that the rest of the world cannot revert to a hunter-gathering and early farming existence, but there are lessons for all of us.
- The Tsimane diet consists of 72% carb sources like rice, maize, and manioc root, 14% – 17% protein from lean meat and fish sources. Their fat intake is 14% as compared to 34% in the US.
- They are far more physically active than most Americans. Men average 17,000 steps a day, and women average 16,000. Even the over-60s have a step count over 15,000. This is not an endorsement for quantitative step counting devices. It points to the benefits of a high degree of physical activity.
- Profesor Naveed Sattar, University of Glasgow, said, “Simply put, eating a healthy diet very low in saturated fat and full of unprocessed products, not smoking and being active life long, is associated with the lowest risk of [blood vessel blockage].”
- Few Tsimane had signs of clogged arteries—even well into old age.
- Dr. Gavin Sandercock: “The fact that they have the best indicators of cardiovascular health ever reported is the exact opposite to many recent suggestions that carbohydrates are unhealthy.”
