The Gut Microbiome: The Invisible World That Controls Your Health

Imagine an ecosystem inside your body, teeming with trillions of tiny organisms, influencing everything from your digestion, to your mood, to your risk of chronic disease. This is the gut microbiome. And while it may be microscopic, its impact on your well-being is anything but small. In fact, it has been found that 70% of your body’s immune system resides in your gut lining - a huge reason why establishing optimal gut health is so important for healthy immune function. 

For years, scientists have known that bacteria live in the human body. But only recently have we begun to understand just how much they control. They communicate with our brain, shape our immune system, and even influence our hormones. The question is, what happens when this delicate balance is disrupted?

Your gut microbiome is a vast and complex community of bacteria, fungi, and other microorganisms that live primarily in your intestines. This ecosystem actively participates in digestion, metabolism, and immune function. In fact, your gut contains more bacterial cells than human cells, meaning, in a way, you’re more microbe than human.

A healthy gut microbiome works in harmony with your body, aiding in the breakdown of food, the production of essential nutrients, and the regulation of inflammation. But when things go wrong, the consequences can be far-reaching.

I would expect that for the majority of people this elicits a degree of fear – a well-known tactic to manipulate people to take the action being suggested and “Donate Now”. But would people fear this statistic less if they were given more information? Instead of feeling powerless to the outcome of that dreaded coin flip, would they feel empowered to direct their fate towards one of health and vitality? My guess would be, probably.
