Gut Health – Byron Bay

Based in Byron Bay, NSW, Todd Mansfield is a student Herbalist focusing his studies on gut health and digestive issues. Blending functional medicine and traditional herbal medicine to look at health from a different perspective.

 

Why Gut Health?

The more time we spend looking into the human microbiome and the variety of different microbes living inside our gut the more important they become.

Many practitioners focus on the individual species residing in the gut, and while it is important to know if you have a parasite infection, bacterial dysbiosis or SIBO (small intestinal overgrowth) it is equally important to know and understand the whole picture.

How are the different phyla represented in your gut?

Up to 1000 different species of bacteria can be living in your digestive tract (mainly your large intestine) but they are made up of only a few different phyla.

Bacteroidetes and Firmicutes dominate in numbers while others include Proteobacteria, Verrucomicrobia, Actinobacteria, Fusobacteria and Cyanobacteria (1).

 

Firmicutes phylum

Is mostly gram-positive bacteria and include

  • Lactobacillus
  • Bacillus
  • Staphylococcus

Firmicutes also includes the Clostridium clusters IV and XIV
This cluster of genera include

The Bacteroidetes phylum,

Is generally gram-negative bacteria, have two predominant genera including

  • Bacteroides
  • Prevotella

The Actinobacteria phylum

This one contains a real favourite

  • Bifidobacterium

 

How Our Microbiome Helps

The microbiota living in our digestive tract contribute to health in an endless number of ways. Researching and listing them all would be a lifetime’s work but a few very important and well researched aspects include the following important points. 

 

The production of short chain fatty acids (SCFAs)

benefits include (2)

  • being an energy source and regulating gene expression for the cells that line your gut 
  • Possibly protects against colorectal cancer and colitis 

The research keeps circling back to short chain fatty acid production. For a deeper dive on this subject here are some recommended readings that include the beneficial impacts that short chain fatty acids can have.

Influence human nutrition and metabolism

Including (3)

  • B-vitamin production
  • K vitamin production
  • release cellular factors that influence human metabolism

 

Immune response and development (4)

There are connections between the gut and every body systems.

The immune system is strongly associated with the state of the gut.

One example of this would be the impact that endotoxins (immunogenic substances found on the cell wall of gram-negative bacteria) can have on the immune system. These substances can set the immune system off in different ways, triggering inflammation and reactivity.

One interesting example of this would be the loss of self-tolerance that seems to be driving (or playing a strong role) in the development of inflammatory bowel disease.

The Microbiome and Disease – An Unhappy Gut

There is more research connecting the gut flora and health and disease than we know what to do with, with more coming out each year.

From these studies we’ve found connection in:

  • IBS – there are seemingly endless studies looking into the altered microbiome as an underlying cause of IBS with different conclusions (5, 6, 7, 8, 9, 10, 11, 12

One study summarised it nicely when referring to all of the studies available saying that – “All (the studies listed) suggest that microbes play a key role in IBS” (13)

  • IBD – Inflammatory bowel disease has comparable scientific research looking into the microbiome and possible alterations or disruptions. As I’ve written about before there is an immune disfunction at the core of IBD that involves the microbiome (15, 16, 17, 18).

One review on the disrupted microbiome and disease outlines the current thinking on IBD and our gut microbes – “Although the aetiology of both diseases is unknown, there is increasing evidence that intestinal microbial dysbiosis has a role in the pathogenesis of IBD” (19)

  • One review paper listed a collection of disease states that have been linked to the microbiome – “Studies examining the composition and role of the intestinal microbiome in different disease states have uncovered associations with inflammatory bowel diseases (IBD), inflammatory skin diseases such as psoriasis and atopic dermatitis, autoimmune arthritis, type 2 diabetes, obesity, and atherosclerosis (20).
  • There are countless more health issues that involve the microbiome. This is the main topic of the articles I published stemming from the research I do.

Happy Gut – Improve Your Digestive Health

While we are still getting to the bottom of the different microbes that make up our individual and completely unique microbiome we do know enough to intervene and nudge your gut health back on track.

Individual species can confer great benefit and some can be pathogenic. Digging in and looking at what makes up one’s own microbiome is a great place to start.  

From there your gut health can be improved by modulating and modifying the microbiome with

  • Prebiotics
  • Probiotics
  • Diet
  • Stress reduction
  • Appropriate exercise
  • Targeted antimicrobial herbs that selectively kill the pathogens and avoid harming your beneficial bacteria
  • Improving detox pathways and drainage
  • Optimising nutrient status and deficiencies

On a personal note a disrupted gut microbiome was my main health issue and something that has plagued me for years.

Going through different herbal protocols trying to kill off the bad bacteria and parasites has led me down a path of a diminishing microbiome.

This is something that I see all the time.

Overuse of antibiotics and repeated use of broad spectrum antimicrobial herbs that results in individuals who don’t feel any better regardless of whether they have eradicated the pathogenic microbes.

One interesting concept, supporting this train of thought, suggests that a disrupted gut allows the growth of the Proteobacteria phylum. In a healthy gut this gram-negative group of bacteria are held in check by the other, more friendly residents. When the gut is disrupted (antibiotics, antimicrobials, surgery, shock, poor diet) this phylum is given room to grow.

Some bacteria that belong to this group include, among others

This leaves me thinking there is something more.

In my mind gut health comes first.

Once your gut has been optimised other body systems will follow.
