Your Microbiome- Bite Sized Series

A balanced, rich, and robust microbiome is one of the major drivers of short term and long term health.

If I could only recommend one area for people to focus to ensure better overall health it would be on protecting and enhancing their microbiome. This is a core Foundation of Health.

Sometimes it feels overwhelming to even discuss the microbiome due to the fact that your microbiome is connected to every body system and cell in your body.

Your acute problem might be hormone imbalance, headaches, stubborn weight gain, chronic pain, insomnia, depression, fatigue, immune issues, skin rashes, boating, etc……………but the root cause could be in your gut.

I have found that no matter what you are trying to heal or repair or rebalance, addressing the microbiome will help everything function better.

To simplify things, we are going to take a ‘bite sized’ approach over time to look at the important roles of the microbiome and what you can do to protect your microbiome.

I will share 1 important function of the microbiome each week with 1 step you can take to optimize it.

But before we go there……… The basics- your microbiome is a unique ecosystem made of bacteria, fungi, viruses, and other single cell animals. We have far more microbes than we have human cells and they cover all the various parts of our body including our gut, skin, mouth, and lungs. These microbes dictate how we feel and how we function and how we age. The science around this is exploding right now as we learn about their important role in aging, energy, disease, autoimmunity, chronic symptoms, weight gain, hormone health, immune health, chronic inflammation and more.

NOTE- If one of these tips does not feel right, LISTEN TO YOUR BODY. It is usually NOT the new habit but instead the state of your gut. You may need to restore a dysfunction or a microbial imbalance before you can use these ideal tips. Easing into one at a time is always best.

Let’s dig in! 1 week at a time.




#1- A Boundary

Week #1- Your microbiome is your major guardian, protecting you from what enters your body.

According to Dr. Kiran Krishnan- Microbiologist at Microbiome Labs, Our gut is where we are most exposed to the outside world.  This is why most of our immune system resides here. 

Our digestive tract is actually considered OUTSIDE THE BODY.  
The guards that protect what is allowed to come into the body are the MICROBES in our MICROBIOME (and the mucus layer they directly impact). If there is an imbalance in your microbiome, there is not proper protection.   (1)

“If your microbiome is robust and diverse there is amazing protection and improvement in our health and wellness in the short term and long term” says Dr. Krishnan.  (2)

We want to absorb nutrients from our food but keep out harmful substances such as mold, viral toxins, bacterial toxins, environmental toxins, undigested foods, etc. 

When this barrier function is not working (aka leaky gut), we can absorb these substances and the result is chronic inflammation.  And the thing is, this chronic inflammation goes above and beyond digestive issues.   In this case we might see symptoms like- brain fog, achy joints, headaches, anxiety, depression, fatigue, and more inflammatory symptoms and disease progression associated with again. 

A leaky gut, which is the root of so many chronic issues, starts with an imbalance in the microbiome, the guards are down and the mucosal barrier is disrupted. And again, digestive issues are not even present in these situations yet, the gut is the root of the problem. 

I have heard this roughly likened to a castle wall (the thin layer of the gut wall) being guarded from invaders by soldiers standing guard (the microbes in your gut). When the guards are few in number, or are made of disruptive characters, invaders can easily get in and the wall is destroyed. The guards are VITAL.

One of the most harmful things that can move across the boundary from the gut into the body and cause problems in this situation are Endotoxins, or toxins made in the body.  These include LPS or lipopolysaccharides that are made from gram negative bacteria.  They belong in the gut but NOT in the bloodstream.  When they enter the body through a leaky gut from an imbalanced microbiome it becomes a highly toxic compound that acts as a root cause for hundreds of chronic illnesses says Dr. Krishnan.  And again, these are NOT digestive issues.  (2)

Week #1 Tip- One way you can protect the health of your microbiome is to EAT A WIDE VARIETY OF FOODS, including all of the colors at every meal. Diversity is KEY as the different microbes eat different foods (think a variety of veggies, fruit, nuts, seeds, beans). Try new foods each week

Each of the different microbes in our gut feed off different foods. This is why a diverse diet is key to long term health above and beyond nutrient wise. Even if you eat a salad every day, change it up, get new veggies, add different nuts, seeds, fruits, fresh herbs, spices, healthy oils, clean proteins, etc. Download my rainbow food tool here to help.

REMEMBER- if eating a diverse diet does NOT feel right, get CURIOUS around what might be going on in your gut and your microbiome. You may need to rebalance your microbes first. (See my video here on HEAL vs IDEAL)




#2- POSTBIOTICS communicate with other parts of your body

Week #2- POSTBIOTICS ARE FUNDAMENTAL FOR OVERALL HEALTH.

The friendly microbes in your gut feed off prebiotics and the result of this process are compounds called postbiotics.  These postbiotics are one important way the microbiome communicates directly with the immune system, the brain, the skin, our hormonal system, and every other cell in the body.  This is huge and we are learning more about this everyday as research in this area is growing fast. 

Short chain fatty acids (SCFA) are a type of postbiotic.  The one SCFA we hear a lot about is Butyrate. Butyrate is a POSTBIOTIC that is made when bacteria in the gut feed off certain fibers. You have to have the good bacteria and you have to feed them the right foods to get these postbiotics that we need for optimal health. 

Butyrate makes us more sensitive to insulin, it helps us to use fat for fuel, it feeds helpful microbes so they can grow, it talks to the immune system, and it is the main fuel for the gut wall so the gut can repair itself and provide a healthy boundary. 

Other postbiotics impact our neurotransmitters including serotonin, dopamine, tryptophan and influences our mood in this way.  Others impact the brain through the vagus nerve and there is a lot of research happening in that area now.  Other postbiotics include B vitamins, vitamin K, amino acids, and antimicrobials that keep harmful microbes from growing (4).

There is growing evidence that certain postbiotics positively impact allergies, eczema, colic, defense against viruses, weight loss, joint pain, eye issues, heart disease, constipation, diarrhea and other IBS and IBD symptoms and may even have anti tumor properties (5,6).

We are continuing to learn a ton about postbiotics and how they important they are for our health and homeostasis. Make sure you have a healthy and diverse microbiome, that you are feeding those microbes well, and that you have the right environment for healthy microbes to grow- and boom, your body will make these essential postbiotics for you. More on how to do all that coming!

Week #2 Tip- Tending to your microbiome is a bit like farming, you need to seed properly, feed them properly, and provide the right environment for the good microbes to grow. When it comes to seeding the right microbes it is important to either eat fermented foods daily, such as sauerkraut, kefir, kimchi, miso, yogurt, or fermented veggies or take a researched and proven effective probiotic regularly (don’t waste your money with so many that do not have proved impacts). I recommend people take specific probiotics a few months each year. Click here to see my favorites and basic protocol for microbiome support.
