What a Hunter-Gatherer Diet Did to a Man’s Gut Bacteria in Just Three Days

After just three days of living and eating with the Hadza gatherer-hunters, the gut flora of a relatively healthy British professor were transformed for the better.




Tim Spector, a genetic epidemiology professor at King’s College London, has been studying the “major influence” gut bacteria (and other microbes) have on our immune system, metabolism, mood and general health. What he and his colleagues have found is the greater the gut flora diversity – the more types of microbes – the better. High diversity is associated with low risk of obesity and all types of disease.

The Hadza have been living peacefully, happily and sustainably in the Great Rift Valley of East Africa for at least 100,000 years. Their home, around Lake Eyasi, in Tanzania, has been called “the cradle of mankind.” A Harvard anthropologist calls them “the strongest link” we have to 2 million years of human evolution. Thanks to the spread of agriculture to nearly every corner of the earth, that link is about to disappear.
