The Microbiome & You | Part One

The Microbiome & You | Part One

Exploring our body’s vast complexities is what makes medical innovation so exciting, and our current understanding of our internal ecosystem — the microbiome — is just being uncovered. The knowledge we once held about common diseases and disorders are now being linked to gut health, so the accepted adage surrounding it all is, heal the gut to heal the health issue.

Healing Digestive Illness takes the convoluted information inundating the media about gut health and provides natural solutions for leaky gut, IBS, and Crohn’s disease. Russell Mariani and his team have devoted their lives to health and wellness through food education so that people can find optimal health and live their best lives. In today’s post, we’ll begin to scratch the surface of the microbiome and how it relates to gut health. 

The Basics of the Microbiome:

Every person has a microbiome — in fact, we are composed of more bacteria than human cells! The microbiome is a beautiful internal ecosystem comprised of microbes. This microbial community inhabits every part of our bodies that are exposed to the external environment including our mouth, nose, skin, and vagina, and they colonize in the gut where a constant supply of nutrients are always available. To put a number on the microbes roaming your body, there are roughly 10 to 100 trillion cells in every person, most of them residing in the digestive tract.

The microbiome is unique to each individual and is, in sense, a genetic imprint because it helps make up our DNA, hereditary influences, and predispositions to diseases. If you’re having a hard time conceptualizing the microbiome, because it’s not necessarily location-specific, an organ, large in size, and has numerous roles, just break down the word for clarity. Micro means small, and biome means a habitat — so the microbiome is a small habitat for living microbes in your body.

Our microbiomes are first developed when we greet our new environment through our mother’s birth canal and nourished thereafter by breast milk — these are the foundations in which our microbiomes are established. As we develop, dietary, familial, and environmental factors all contribute to our microbiome to help cultivate an ecosystem that will impact our health over our lifetime.

Why Does the Microbiome Matter?

Both healthy and harmful bacteria can roam our internal environment, and when the balance is tipped and the harmful bacteria flourish, naturally, illness takes root. What really needs to be understood is that bacteria is beneficial to us, and our attempts to sterilize our environment, and with the increased usage of antibiotics, disrupts the natural balance and kills beneficial bacteria. As more research continues to develop, scientists are finding that microbes are linked to virtually every process in our bodies, including immune health, psychological concerns, and disease states — obesity being of concern — so the more we understand how it functions, the better we can treat illness and support optimum health.

Research has found that there is a symbiotic relationship between the microbiome and us. We provide a cozy environment with plenty of nutrients, and the microbes, in turn, give us a by-product to maintain healthy biological processes.

Because we’re still in our infancy in understanding the microbiome, it’s exciting to see where it progresses and how people will ultimately find health and wellness through it.

Throughout this post, we scratched the surface on what the microbiome is and how it influences our health, in addition to why it matters. We’ve found that the microbiome is unique to everyone and is crucial in the support it gives us when it’s in an ecosystem set up to thrive. It matters and it impacts us on a deep, health level, including our immune health, mood and psychological issues, and disease states. Every day new studies are finding direct links to obesity, dementia, and autoimmune disorders when poor gut health is found.

Making wise and protective health decisions will only benefit your microbiome. Stay tuned for part two as we examine specific ways to create a healthy gut ecosystem!
