'Tribes with 70% slower brain aging' live in the Amazon

It is known that the

Chimanes, who live a self-sufficient life in the rainforests of Bolivia, have significantly different constitutions and cultures than those who live in modern times. A new study has been reported on the Chimane tribe that 'the aging of the brain is 70% slower than people living in other areas.'

Since the Chimanes live in the rainforests of Bolivia and live a self-sufficient life isolated from modern culture, many studies have been conducted focusing on their lifestyle, health condition, culture, etc. I have come.

Among the many studies on the Chimanes, the 2017 Study on the Heart Health of the Chimanes revealed a very low incidence of heart disease in the Chimanes. Attention was focused on the possibility that a self-sufficient lifestyle rooted in hunting, gathering, fishing and agriculture of the Chimane tribe has a great deal to do with health.

In a new study, CT scans of the brains were performed on 746 Chimanes aged 40 to 94 years, and the brain volume was calculated from the scanned images of people living in industrial areas in the United States and Europe. Compared with brain volume. As a result, it was revealed that the atrophy of the brain volume of the Chimanes from middle age to old age is 70% less than that of Westerners.

'In general, inflammation is associated with atrophy of the Western brain,' the researchers said. However, in this study, a high level of inflammation was confirmed from the Chimane tribe. This raises questions about the theory that inflammation is the cause of brain atrophy.

'Our sugar- and fat-rich diet and sitting work accelerate age-related brain atrophy,' said Hillard Kaplan, a member of the research team who has been studying the Chimanes for nearly 20 years. It may be letting you do it. '

'The results of this study show that even patients who experience a lot of inflammation can improve their brain health,' Kaplan said. 'The Chimane lifestyle helps maintain brain health.' Pointing out the possibility.
