The Tsimane, an indigenous community of around 16,000 people in the Bolivian Amazon, are recognised for having some of the healthiest arteries and slowest-ageing brains in the world. Living a semi-nomadic lifestyle focused on hunting, foraging, and farming, the Tsimane are largely isolated from modern influences, which has preserved their traditional way of life. This lifestyle, which includes constant physical activity and a diet low in fat and high in fiber, has contributed to their exceptional cardiovascular and neurological health.

Over the past two decades, researchers led by anthropologist Hillard Kaplan of the University of New Mexico and Michael Gurven of the University of California, Santa Barbara, have studied the Tsimane extensively. Initially focused on anthropological aspects, they soon observed that elderly Tsimane did not exhibit common age-related diseases such as hypertension, diabetes, or heart problems.

Collaborating with a US cardiologist, they conducted CT scans on 705 Tsimane over the age of 40 to look for coronary artery calcium (CAC), an indicator of heart disease. The results, published in The Lancet in 2017, revealed that 65% of Tsimane over 75 had no CAC, a stark contrast to the 80% of Americans in the same age group who do.

Further research, published in the Proceedings of the National Academy of Sciences, showed that elderly Tsimane experienced up to 70% less brain atrophy than their counterparts in industrialised nations like the US, UK, and Japan. The researchers even found no cases of Alzheimer’s among the adult Tsimane population, a finding described as remarkable.

The occasional few survive to 70 but the average life span for these people is less than 50 years.

Yes the basics of, daily activity and a more “natural” diet impart a lot of benefits but having clean water, antibiotics, a functional health care system, etc is still critical for a long life.

Ok. Truth be told, you may be heart disease free if you live in an Amazon pre-industrial tribe.

How many people here qualify for that cohort or are considering becoming a bushman?

For the rest of us, there’s statins, bempedoic acid and ezetemibe.

Even 35 per cent of the bushmen could have benefited from a statin despite their perfect diet.
