AMAZON DIET KEY TO LONGER LIFE SPAN?

Indigenous peoples living in the Amazon have brains that degenerate 70 percent slower than Western populations, a new study has found.

Euronews reported on an experiment, produced by the University of Southern California (USC), which found that the Tsimane indigenous peoples of the Bolivian Amazon experience significantly less brain atrophy than their American and European peers due to distinct lifestyle differences.


Brain atrophy is commonly linked with cognitive impairments, functional decline, and illnesses such as dementia. An aging population survey by the OECD estimates that by 2040, almost 10 percent of Europeans will be living with dementia-related illnesses.

Could a plant-based diet keep our brain capacity stable throughout old age?


Over 700 Tsimane adults aged 40 to 94 agreed to participate in CT scans that would calculate their brain volumes in connection to their age. These findings were then compared with three industrialized populations in the US and Europe.


The explanation can be found in diet and physical activity. Scientists attribute the people of Tsimane’s neural longevity to their intake of food that is high in fiber and low in saturated fats, along with their physically mobile way of life.

Though the area has little access to modern healthcare, this is counterbalanced with their lifestyles, the opposite of the more sedentary living in the West. High supplies of fruits, vegetables, and sustainably sourced fish have kept Tsimanes in better health.


USC notes that the Tsimane have high levels of inflammation, which is typically associated with brain atrophy in Westerners. Despite this, their study suggests that high inflammation does not have a pronounced effect on Tsimane brains.
