Introduction
They say health starts in your belly- and in 2025, it is showing into science. There is a rising tide of a cult of gut health and probiotics and the miraculous power of the microbiome sweeping the UK. As fresh science has provided links between the gut and immunity, mental acuity, weight management and even mood, a previously ignored area of the body is now superstar status in the wellness marketplace.
So lets talk about why stomach wellness is the new cool in the UK, what exactly it implies about your general health, what and how to do to take care of this little ecosystem of 500+ species within your belly.
What is the Gut Microbiome?
The microbiome is a collection of trillions of microorganisms—bacteria, viruses, fungi—that live mainly in your gut. They:
Assist in the breakdown of food
Synthesize such vitamins as B and K
Control the immune system
Direct your mood and brain through the gut-brain axis
Avoid the invasion of dangerous pathogens
Think of your microbiome as a garden: if you feed it well and take care of it, it blooms. But if neglected, it gets overrun with weeds.
