Gut health plays in pivotal role in your overall well-being — a topic I explored in-depth in my interview with Dr. Vincent Pedre, an internist with a focus on functional medicine and gut health. Our discussion covered the intricate connections between your gut microbiome, diet, antibiotics and chronic diseases, revealing why your gut is often the cornerstone of chronic health issues.
Gut health is not just about digestion; it’s the foundation upon which your immune system, mental health and even your skin health stand. Pedre and I explored how modern lifestyles, characterized by processed foods and excessive antibiotic use, have disrupted the gut microbiomes of the population at large, leading to a surge in chronic diseases.
Growing up as the child of Cuban immigrants, Pedre’s early diet was heavily influenced by the processed foods of the 1970s and ‘80s — sugary cereals, refined bread and pasta. This unbalanced diet, coupled with frequent antibiotic use for recurrent throat and sinus infections, had a profound impact on his gut health.1
By the age of 19, he had undergone over 20 rounds of antibiotics, including Cipro, a fluoroquinolone known for its devastating effects on the gut microbiome. This extensive antibiotic exposure eviscerated his beneficial gut bacteria and led to sensitivities to wheat and dairy, which ultimately shaped his passion for gut health.
Your Gut as the Foundation of Health
Your gut plays a multifaceted role in several seemingly unrelated bodily systems. The gut-brain axis, for instance, illustrates how gut health directly impacts mental clarity and emotional well-being. Similarly, the gut-skin connection highlights how digestive health influences dermatological conditions.
The interplay between your gut and your immune system is particularly important, as a healthy gut microbiome is essential for robust immune responses. Moreover, your gut’s relationship with metabolic health influences conditions like diabetes and obesity.
Despite its importance, mainstream medicine often overlooks the gut’s central role, primarily due to conventional medical education's limited focus on functional medicine principles. This gap has led to an underappreciation of the gut’s influence, with many physicians not fully recognizing how deeply gut health is intertwined with overall wellness.
Functional medicine practitioners like Pedre adopt a holistic approach, viewing the body as an interconnected system where gut health is a key component. This perspective allows for a more comprehensive understanding of chronic diseases, facilitating targeted interventions that address the root causes rather than merely alleviating symptoms.
Understanding Microbiome Diversity
During the interview, we explored the concept of microbiome diversity and what constitutes a healthy microbiome. Pedre drew attention to studies of the Hadza, one of the last hunter-gatherer groups on Earth, whose gut microbiomes are remarkably diverse and resilient.2
The Hadza tribe in Africa is among the best still-living representations of the way humans have lived for tens of thousands of years. Unlike Western populations, the Hadza do not suffer from common chronic diseases like diabetes, heart disease or obesity. Their diet centers on wild berries, tubers and lean meats.
Their diverse gut microbiomes are attributed to their natural lifestyle, including exposure to dirt and environmental microbes, which fosters a robust and adaptable gut microbiome. The Hadza's diet, though not colorful in the Western sense, is rich in fiber and free from processed foods and seed oils, promoting the growth of beneficial bacteria that effectively combat inflammation and disease.
In contrast, modern lifestyles, characterized by processed foods rich in linoleic acid (LA), excessive antibiotics, environmental toxins and limited exposure to natural environments, have significantly disrupted microbiome diversity. This disruption contributes to the prevalence of chronic diseases in Western societies, highlighting the need for strategies that restore and maintain a diverse and balanced gut microbiome.
Differentiating Beneficial and Pathogenic Bacteria — The Role of Oxygen and Mitochondria
One of the most important insights from our discussion revolves around the delicate balance between beneficial and pathogenic bacteria in your gut. Antibiotics tip this balance disastrously, but so does exposure to mitochondrial poisons like LA, endocrine-disrupting chemicals in microplastics, estrogens and electromagnetic fields (EMFs).
An estimated 99% of your gut bacteria reside in your colon (large intestine) — the end section of your digestive tract where stool is formed — where they play distinct roles. The small intestine contains relatively few species of bacteria due to high levels of oxygen.
Facultative anaerobes (pathogenic bacteria) tolerate oxygen, while obligate anaerobes (beneficial bacteria) only thrive in the oxygen-free environment of your colon. This distinction is fundamental because oxygen is inherently toxic to beneficial gut bacteria.
Under normal conditions, oxygen levels in your colon are maintained at less than 0.1%, a stark contrast to the 20% to 21% oxygen levels in the atmosphere. This low-oxygen environment is essential for the survival of beneficial bacteria, which are remnants from primordial Earth when oxygen was scarce.
When your mitochondrial function is impaired and cellular energy production is low, the tight junctions in your colon begin to fail, allowing oxygen to leak into your colon. The introduction of oxygen creates a hostile environment for beneficial bacteria and allows pathogenic bacteria to take over. The introduction of antibiotics, which kill both beneficial and pathogenic bacteria, causes even further disruption.
The end result of this chain reaction, which began with insufficient energy production, is a condition called dysbiosis.
This topic is covered in detail in my newest book, "Your Guide to Cellular Health: Unlocking the Science of Longevity and Joy." Mitochondrial health is key to overall health, because your mitochondria are responsible for producing the energy necessary for all bodily functions, including the energy necessary to maintain the tight junctions between cells in your colon.
As pathogenic bacteria proliferate, they produce endotoxins that damage your gut lining, creating tiny holes that allow foreign proteins to enter your bloodstream and oxygen to enter your colon. This oxygen influx further disrupts the gut environment and reinforce the cycle of dysbiosis.
Without a robust and balanced microbiome, restoring gut health becomes nearly impossible, trapping individuals in a perpetual state of decline. Addressing this complex interplay requires more than just supplementing with probiotics. Even the best probiotics often fail to survive the journey through your small intestine.
If the capsule disintegrates in the small intestine, the probiotics will be decimated by the oxygen present and won’t make it to their end destination, your colon, alive.
Therefore, to regain your health, your treatment strategy must focus on restoring the health of colonocytes — the cells lining your colon — by eliminating mitochondrial poisons that undermine cellular energy production. Only then will the beneficial oxygen-intolerant bacteria regain their foothold and restore your gut's natural balance.
By creating an optimal environment for these beneficial bacteria, you can break the cycle of dysbiosis and pave the way for lasting gut health restoration.
Dietary Strategies for Gut Restoration
Diet plays an important role in restoring and maintaining gut health. One of the most important dietary interventions is to radically lower your consumption of processed foods. This will reduce your intake of polyunsaturated fats (PUFAs) such as LA, which are inflammatory and detrimental to your microbiome.
As Pedre points out, even seemingly healthy diets, such as veganism, are problematic if they are high in omega-6-rich seeds and nuts, as they promote inflammation and microbiome imbalance.
Aside from that, Pedre advocates for low-carb and carnivore-like diets as an initial step to reduce pathogenic bacteria by limiting their fuel sources. These diets focus on eliminating vegetables and lectin-rich foods that are harsh on a compromised gut, providing a temporary reprieve that allows your gut to begin healing.
However, I caution against the long-term use of such restrictive diets due to the metabolic consequences, including elevated cortisol levels and muscle loss. Reintroducing carbohydrates is essential for mitochondrial health, as glucose is the preferred fuel for cellular energy production.
In my new book, I propose that dextrose water can act as a bridge for severely ill patients who are unable to tolerate most carbohydrates without severe side effects. Unlike complex carbohydrates, dextrose is absorbed in your small intestine. By not feeding bacteria in your large intestine, it helps prevent the production of endotoxins. This approach allows for the gradual restoration of gut health without exacerbating dysbiosis.
For many, this radical of an approach won’t be necessary though. It’s really only intended for those with severely compromised gut health. Most people with poor gut health will be able to begin their gut restoration using white rice and whole fruits. As your gut health improves, you’ll then be able to incorporate more fiber-rich vegetables and starches into your diet without ill effects.
Targeted Supplementation and Therapeutic Approaches
Supplementation significantly assists in gut restoration, provided it is targeted and based on individual needs. Butyrate, a short-chain fatty acid produced by beneficial gut bacteria, is important for colonocyte health and gut barrier integrity. Pedre uses both oral and enema forms of butyrate to rapidly reduce inflammation markers like calprotectin in patients with severe gut conditions such as ulcerative colitis.
In the interview, I also discussed my efforts to innovate better delivery systems for butyrate to ensure it reaches the colon intact without being diffused in the small intestine. Pomegranate extract and citrus bioflavonoids are also effective agents for rebuilding the mucus layer in your gut. These polyphenol prebiotics support the growth of beneficial bacteria without causing gas and bloating, unlike many prebiotics.
We also discussed the importance of selecting the most effective probiotic strains, such as Akkermansia, a keystone gut microbe, and other oxygen-intolerant bacteria like Clostridia, which produce butyrate and support a healthy microbiome balance. Unfortunately, most of the probiotic formulations on the market are useless, as the bacteria don’t survive the journey to your colon.
Innovations in encapsulation technologies, such as delayed-release systems, are being developed to address these issues. This will ensure that beneficial bacteria reach their intended destination alive. If they all die in transit, they won’t do you any good, as dead bacteria cannot replicate and repopulate in your colon.
Addressing Small Intestinal Bacterial and Fungal Overgrowth
Small intestinal bacterial overgrowth (SIBO) and small intestinal fungal overgrowth (SIFO) present significant challenges in gut health management. Pedre noted that many Western doctors misdiagnose SIBO and treat it with antibiotics like rifaximin, which inadvertently triggers yeast overgrowth, making gut dysbiosis worse.
This dual imbalance further complicates treatment, requiring comprehensive approaches that address both bacterial and fungal pathogens simultaneously.
According to Pedre, more effective treatment strategies involve using a combination of prescription and herbal antifungals to eliminate fungal overgrowth while simultaneously targeting pathogenic bacteria. Treating SIBO without also addressing underlying fungal issues leads to persistent and worsening symptoms, underscoring the need for expert holistic intervention in these complex cases.
The Role of Stress Management in Gut Health
Stress management is another component of gut health, as chronic stress impedes the healing process and worsens gut dysbiosis. Pedre highlighted that severe gut issues often correlate with heightened stress levels, whether perceived or physiological. Techniques such as breath work and personalized meditation practices help shift your body into a parasympathetic, relaxed state that facilitates gut healing.
However, traditional meditation has some paradoxical effects. Improper techniques sometimes lead to overbreathing and reduced CO2 levels, which can actually worsen symptoms. Instead, I advocate for shallow, slow breathing practices that allow CO2 levels to rise. This enhances oxygen delivery to tissues, reduces panic responses, and supports better mitochondrial function and overall cellular health.
As I explain in my upcoming book, "The Power of Choice," any activity that induces a sense of timelessness or "being in the zone," such as playing an instrument or engaging in hobbies, are also powerful tools for stress reduction.
By integrating stress management into your gut health protocol allows you to address both the physical and psychological factors that contribute to your digestive issues. By balancing your autonomic nervous system, you create a supportive environment for your gut to heal and thrive.
Environmental Factors Affecting Your Gut
Beyond diet and stress, environmental factors also play a significant role in gut health. Endocrine-disrupting plastic chemicals, found in water bottles and everyday products, disrupt your gut microbiome by activating estrogen receptors in your body and interfering with metabolic pathways.
To minimize exposure to microplastics and other environmental toxins, use glass or stainless steel water bottles, avoid plastic containers, reduce exposure to EMFs and choose organic, non-GMO foods to reduce intake of glyphosate and other harmful chemicals.
Embracing a Holistic Approach to Gut Health
Beyond key lifestyle changes like avoiding LA and other mitochondrial poisons, the future of gut health management lies in innovative testing and supplementation technologies. I’m developing affordable, targeted microbiome tests that focus on identifying key beneficial bacteria that are essential for a healthy gut. These tests will provide actionable insights at a fraction of the current cost, making them accessible to a broader population.
I strive to make personalized gut health assessments and tailored therapeutic interventions into standard practice, enabling individuals to restore and maintain a balanced microbiome with precision and efficacy.
These kinds of innovations hold the key to changing how we approach chronic diseases, moving from reactive treatments to proactive, preventative strategies. I firmly believe that by leveraging cutting-edge technologies, we’ll reach a new era in gut health and overall wellness.
