Zach Bush MD, is an internationally recognized educator and thought leader on the microbiome as it relates to health, disease, and food systems. Celebrating  World Microbiome Day on 27th June 2021, he explained why there’s no better time to pay tribute to the microbiome. 

“As human beings, our neurologic capacity begins with our connection to the microbiome”  Zach Bush MD

In his latest weekly newsletter,  Bush said,  “It is, in its entirety, vital to life and the reason why we are here today. Without the microbiome, life on Earth would not exist.”

“At its most basic definition, micro means small, and biome means living creatures — essentially all the living microbes on and inside the human body. Today, we know human cells are not at the foundation of the human microbiome, but rather it’s the fungi and bacteria that are. It is estimated that we have 50 to 70 trillion human cells, which pale in comparison to the 1.4 quadrillion bacteria and 10 quadrillion fungi inside our bodies.”

He further explained that as we learn more about the microbiome and our human biology, it’s clear that this diverse non-human micro-ecosystem is what makes life possible. “It’s what fuels our development, immunity, and nutrition, enabling our production of energy, micronutrients, and regenerative pathways. Within every organ system throughout our whole body, it’s this unique niche of bacteria, fungi, and yeast that nurtures our human cells.
