Environmental Exposures--Beyond Diet and Exercise--Impact Health

Modern Wisdom · December 27, 2025 · Listen to Original Episode →

Original Title:

TL;DR

Environmental exposures, beyond diet and exercise, are a critical third pillar of health, with increasing prevalence of issues like mold, microplastics, and heavy metals impacting well-being.
Standard medical diagnostics often miss environmental illnesses due to a lack of validated tests and a focus on known biomarkers, leading to patient suffering and diagnostic uncertainty.
Parasitic infections, often asymptomatic and difficult to detect with standard PCR tests, can cause chronic blood loss, anemia, and organ damage if left untreated.
Mold exposure can trigger significant adverse reactions like brain fog, fatigue, and rashes, even in buildings that have undergone remediation, suggesting a complex individual sensitivity.
The medical field faces a significant challenge in addressing complex environmental illnesses, often requiring a multidisciplinary "team sport" approach beyond traditional, algorithm-based medicine.
Genetic predisposition plays a crucial role in how individuals respond to environmental toxins, explaining why some people are severely affected while others in the same environment remain asymptomatic.
Emerging research suggests a shift in focus from body fat percentage to the quality of muscle tissue and fat infiltration within it as more valuable health biomarkers.

Deep Dive

The pervasive influence of environmental factors on health is a critical, yet often overlooked, dimension of well-being, extending far beyond traditional diet and exercise. This emerging understanding reveals that complex illnesses, including fatigue, brain fog, and chronic pain, are frequently triggered or exacerbated by unseen environmental exposures like mold, parasites, and microplastics, challenging conventional medical diagnostics and demanding a more holistic approach to patient care.

The implications of this environmental health paradigm are profound and multifaceted. First, it fundamentally shifts the responsibility for health from solely individual lifestyle choices to a dynamic interplay between personal biology and the surrounding environment, necessitating a re-evaluation of diagnostic tools and treatment protocols. For instance, standard medical tests may not detect issues like mold exposure or certain parasites, leading to prolonged suffering and misdiagnosis. This diagnostic gap means patients often become "medical nomads," seeking answers across multiple practitioners, highlighting the need for better interdisciplinary collaboration and the integration of the "art of medicine" -- listening to and trusting patient narratives even when conventional labs appear normal.

Second, the increasing prevalence of these environmental toxins, coupled with potential genetic predispositions, creates a complex web of health challenges that can manifest differently in individuals, even within the same household. This variability underscores that what might be a minor irritant for one person could be a significant trigger for another, explaining why some individuals develop chronic conditions while others remain seemingly unaffected. The downstream effects of these undetected or poorly understood exposures can be severe, impacting nutrient absorption, immune function, and even increasing the risk of serious diseases like cancer and Parkinson's.

Finally, the medical establishment's traditional focus on clear, quantifiable biomarkers and established treatment algorithms struggles to keep pace with the nuanced and often insidious nature of environmental illness. This creates a significant barrier for both clinicians seeking to address these issues and patients experiencing them, often leading to skepticism and dismissal by peers and the broader medical community. The path forward requires a unification of efforts, encouraging open-mindedness among practitioners, investing in research for novel diagnostic methods (such as microscopy for parasites or advanced environmental testing), and embracing modalities like sauna therapy, which evidence suggests can aid in the detoxification of fat-soluble chemicals.

Ultimately, recognizing and addressing environmental factors is not merely about treating symptoms but about fundamentally re-framing our understanding of health. It demands a proactive, integrated approach that acknowledges the body's intricate connection to its surroundings, moving beyond the limitations of conventional diagnostics to uncover and resolve the root causes of complex, modern illnesses.

Action Items

Audit home environment: Test for mold and VOCs in living spaces to identify potential exposure sources.
Track personal symptom correlation: Log daily symptoms (e.g., fatigue, brain fog, rashes) and correlate with time spent in specific locations or exposure events.
Implement sauna protocol: Engage in 30-60 minute sauna sessions at 113-176°F 3-5 times per week to support detoxification of lipophilic chemicals.
Evaluate gut health markers: Test for H. pylori and gut permeability indicators (e.g., zonulin) to assess digestive system integrity.
Research genetic sensitivity factors: Investigate personal genetic predispositions that may influence sensitivity to environmental toxins.

"You had two original pillars of health which were diet and exercise but then you had to add a third one how come the third one uh was environment and is environment i do you have time for a quick story i graduated medical school obviously and then did my fellowship and when you finish your fellowship and go into private practice you kind of think you know everything and i was convinced the key to health was diet and exercise it was all lifestyle and i was wrong"

Dr. Gabrielle Lyon explains that her initial medical training focused solely on diet and exercise as the primary drivers of health. She admits her early conviction was incorrect, highlighting a shift in understanding that led to the inclusion of environmental factors as a crucial third pillar of health.

"it's both we have more exposures than arguably we've ever had now with microplastics and we are getting better at acknowledging and detecting it but we're still not there so for example mold mold exposure this is we hear a lot about it now in terms of buildings with mold or locations and this musty smell and oftentimes we think that it really doesn't affect people however there are certain people that will move into these buildings walk in there break out in a rash have brain fog fatigue feel terrible and it's this exposure to mold mycotoxins but the reality is for a testing perspective we don't have validated tests for mold however i i think it's really important that we test for it but it's not like you walk in and you do a a blood glucose test and there's this diagnosis of diabetes cut and dry we don't have that"

Dr. Lyon addresses the increasing prevalence of complex illnesses by stating it's a combination of more environmental exposures, such as microplastics and mold, and improved detection methods. She notes that while mold exposure is increasingly discussed, validated diagnostic tests are still lacking, making it a challenging area to definitively diagnose compared to conditions like diabetes.

"and i will tell you this and this is quite disappointing is the way that we test for parasites is standardized and it's called a pcr test someone goes and you do a stool sample maybe you do a three day stool sample something of that sort it is supposed to catch nearly all of it it's very sensitive 95 to 100 sensitivity that is not what we have found and you know i've had one patient where we would continue to do these pcr testing but they were very symptomatic and we couldn't figure out why she wasn't coming back positive we sent them to an old school parasitologist where they do a rectal exam take a stool sample look at it under a slide and it turned out that he had a handful of worms i know it's gross and disappointing but the reality is while we think that these parasites are easy to test for and in theory they should be i and many other providers are not seeing that in real life practice"

Dr. Lyon expresses disappointment with the current standard for testing parasites, the PCR test, stating that in her practice, it is not as effective as expected. She contrasts this with an "old school" microscopy method used by a parasitologist, which successfully identified worms in a symptomatic patient whose PCR tests were negative, indicating a potential gap in current diagnostic capabilities.

"medicine is built for following algorithms medicine is built for being able to create a standard of care if you have a heart attack you're in the er you will get this this and this this is when you go to the cath lab this is when you don't and that is how from my perspective medicine is created and where we fall back on where healing comes from is the ability to solve both the complex problems but also recognize the entity i e the human that is experiencing these problems these challenges and that is where there's the art of medicine and the art of healing comes in"

Dr. Lyon explains that traditional medicine is structured around algorithms and standardized care for well-defined conditions like heart attacks. She posits that true healing, especially for complex issues, requires moving beyond these algorithms to incorporate the "art of medicine," which involves recognizing and addressing the individual patient experiencing the challenges.

"i think environmental medicine is certainly the way of the future and i'll say something else i think that we have to re evaluate the old biomarkers that we've been using i know this is going to sound crazy but we've been focusing on body fat percentage as if this is just an example as if this is the biomarker i think that that is going to become less of a valuable biomarker i think that we are going to begin to see that it's the fat the intramuscular adipose tissue it's the quality of the muscle tissue the fat that infiltrates into that tissue is going to be arguably more valuable than understanding someone's body fat percentage in the next five years"

Dr. Lyon asserts that environmental medicine is the future of healthcare and advocates for re-evaluating current biomarkers. She suggests that traditional metrics like body fat percentage may become less important, with intramuscular adipose tissue and the quality of muscle tissue potentially becoming more valuable indicators of health in the coming years.
