In the past, our natural human microbiomes were tailored to our local and culturally traditional food supply

Growing your own food is more than just being economical or fresh. It helps to build a local biome rather than relying on the mixed biome from foods around the world. And because that chain of command has been so reliable we often don't question it or bother to cater to our own individual microbiome closer to home.

From page 88 of Sabine Hazan's Let's Talk Shit:

In the past, our natural human microbiomes were tailored to our local and culturally traditional food supply.  Now, we ship foods all over the planet, resulting in a worldwide microbiome shift.  Is this good or bad?  If we know that decreasing microbial diversity is linked to obesity, it could be good.  But we also know that the introduction of new bacteria can come with costs.  There may be bacteria introduced in our food chain that our own microbiome is not accustomed to that causes dysbiosis.  These are questions that can only be answered by research and time. 

Dr. Sabine Hazan on gut biome

Dr. Sabine Hazan's website, Progenabiome. 

She's referenced Dr. Thomas Borody.  whom she calls the pioneer of fecal transplant.   

Fecal transplant is the process of taking fecal matter from a health donor to one who is ill.  And then little by little, 

In your microbiome, you have trillions and trillions of microbes, most of which are bacteria.  A small minority are viruses and parasites.  When you look at your feces in the toilet, what you're actually looking at are trillions and trillions of bugs.  Each one of these bugs is interconnected with another bug to do something.  In other words, you cannot get rid of one group of microbes because it supports another group of microbes.  So, it's all intertwined, and when you start looking at the depth of the biome, at the species, you start seeing how every microbe is instrumental and so important and its diversity.  The more diverse the microbiome is the healthier the person is.  Non-diversity is disease.  So, diversity is so important . . . it's the Ruminococcus with the Bacillus bacteria with the bacteroides, with the bifudobacterium, with the lactobacillus.  All of it together and they're all living together in a balance and it's amazing to see that. 

As she was looking at the SARS-Co-2 in her lab, she was also looking at the different strains or mutations of the virus.
