You may have heard of the “Hadza diet” as a new way to promote a more diverse microbiome in your body. Here’s some information about it.
The Hadza And Gut Bacteria
The Hadza are an African tribe in Tanzania, in which hundred of them are hunter-gatherers- in other words, they only eat “what they find in the wild.”
A new study decided to look closely at the biological effects of the “Hadza diet.” They compared 350 Hadza stool samples to ones from around 17 other tribes and cultures, including people from the West and other developed countries.
The researchers found that their gut bacteria were not only more diverse than those of people on Western diets, but also varied between seasons.
Unfortunately, Western diets cause people to lose important gut bacteria that are essential to our wellbeing. Therefore, shifting your diet more towards a Hadza one could be beneficial for your overall health.
“I think this finding is really exciting,” said Lawrence David. “It suggests the shifts in the microbiome seen in industrialized nations might not be permanent—that they might be reversible by changes in people’s diets.”
Justin Sonnenberg, a Stanford University professor, commented on the importance of Fiber, saying: “Fiber’s all that’s left at the very end of our digestive tract where these microbes live, so they’ve evolved to be very good at digesting it.”
“The Hadza get 100 or more grams of fiber a day in their food, on average. We average 15 grams per day.”
So What is The Hadza Diet?
Since the Hadza only eat what they find in the wild, what they eat drastically changes per season, and is probably now changing every year given climate change. In dry seasons, they eat mainly tubers and meats, and during wetter seasons, ate more honey and berries.
The interesting thing about the research, is that they found Hadza people’s “dry season” bacteria that disappeared during the wet season, reappeared again in the following dry season. This means that hope is not lost for the non-diverse gut bacteria in the Western world. Changing your diet can effectively bring prosperity back to your gut microbiome.
