Some conversations are less about arriving at definitive answers than they are about examining the assumptions beneath them. This exchange became an exploration of health, physiology, medicine, and the language we use to describe the body itself. Whether one agrees or disagrees with the perspectives presented, the value lies in slowing down long enough to question inherited narratives and consider the possibility that our models of understanding are always evolving.

.   .   .

In this discourse we explored the role of the liver, the body’s methods of processing and eliminating substances, the nutritional value of organ meats, and broader questions surrounding physiology, illness, and healing. The discussion gradually expanded beyond nutrition into competing models of medicine, the relationship between symptoms and adaptation, the influence of language on perception, and the importance of remaining open to questioning foundational assumptions while recognizing the complexity of the human body.

Key Points Discussed

• The liver functions primarily as a processing organ rather than a storage site for toxins.
• Liver has historically been regarded as one of the most nutrient-dense foods available.
• Vitamin A intake is best understood through context rather than generalized recommendations alone.
• Individual physiology varies considerably, limiting the usefulness of population-wide nutritional guidelines.
• The body’s detoxification systems work cooperatively through the liver, kidneys, lungs, skin, bile, and digestive tract.
• Heavy metals differ from many other compounds because of their tendency to accumulate within the body.
• Chronic environmental and lifestyle exposures may contribute to long-term physiological burden.
• Symptoms can be interpreted as adaptive or protective responses rather than isolated malfunctions.
• The relationship between conventional medicine and alternative models remains an area of ongoing philosophical and scientific disagreement.
• Terrain theory and pleomorphism were discussed as alternative frameworks for understanding health and disease.
• Reductionism has yielded valuable medical advances while potentially obscuring the interconnected nature of human physiology.
• Language and terminology shape the questions we ask and the conclusions we reach.
• Genuine inquiry benefits from examining underlying assumptions rather than defending established positions.
• Health may be understood as an ongoing process of adaptation, repair, and resilience rather than merely the absence of symptoms.

Key Takeaways

• Models of health influence both observation and interpretation.
• Context often matters as much as isolated biological mechanisms.
• Symptoms deserve thoughtful consideration rather than automatic suppression.
• Remaining intellectually curious is more valuable than becoming attached to any single framework.
• Careful observation and continued questioning remain essential to understanding human health.

Let’s talk liver. As I understand it, it filters the blood, but it doesn’t store toxins. Eating liver has long been recommended, as it allegedly contains some of the best nutrients that are bioavailable and easily digested by humans. Some say to stay away from eating it because of the nature of its function.

» ChatGPT:

This is a great topic because it sits right at the intersection of physiology, nutrition, and a persistent cultural myth.

The short answer is: the liver is a processing organ, not a toxin warehouse.

Here’s what it actually does.

The liver receives blood from the digestive tract via the portal vein. Everything you eat passes through it first. Its jobs include:

• Breaking down drugs, alcohol, hormones, and metabolic waste.
• Converting potentially harmful substances into compounds that can be excreted in bile or urine.
• Producing bile to aid fat digestion.
• Storing nutrients like glycogen, vitamin A, vitamin B12, copper, and iron.
• Synthesizing proteins, cholesterol, and clotting factors.

Notice that last part about storage: it stores nutrients, not generally “toxins.”

So where do toxins go?

Many toxins are:

• Chemically modified by liver enzymes.
• Excreted into bile and eliminated in feces.
• Sent to the kidneys and excreted in urine.
• Exhaled through the lungs (alcohol, ketones, some solvents).
• Broken down into harmless metabolites.

If the liver simply accumulated toxins indefinitely, it would quickly become nonfunctional.

What about heavy metals and contaminants?

This is where the nuance comes in.

The liver can contain higher concentrations of certain substances because it’s actively processing them.

Examples include:

• Cadmium
• Lead
• Mercury (depending on the animal’s diet)
• Persistent organic pollutants (PCBs, dioxins)

But this isn’t because the liver is a “garbage dump.” It’s because these compounds are difficult for any tissue to eliminate completely.

The same is true of:

• kidneys
• fat tissue
• bone

In fact, fat often stores far more persistent pollutants than liver, because many environmental chemicals are fat-soluble.

Why has liver been prized as food?

From a nutritional standpoint, liver is extraordinary.

A relatively small serving provides abundant:

• Vitamin A (retinol)
• Vitamin B12
• Riboflavin (B2)
• Folate
• Choline
• Iron (highly bioavailable heme iron)
• Copper
• Zinc
• Selenium
• CoQ10 (especially beef liver)

Before synthetic vitamins, liver was essentially nature’s multivitamin.

It was famously used to treat pernicious anemia decades before vitamin B12 was discovered because clinicians observed it worked remarkably well.

The one nutrient to be careful with: Vitamin A

This is probably the biggest legitimate concern—not toxins.

Beef liver is extremely rich in preformed vitamin A.

For most healthy adults:

• A 3-ounce (85 g) serving can provide several times the recommended daily intake.
• Eating liver once every week or two is generally considered reasonable.
• Eating large amounts every day could eventually lead to hypervitaminosis A.

Pregnant women are often advised to avoid excessive liver consumption because very high intakes of preformed vitamin A have been associated with fetal developmental risks.

Does eating liver expose you to toxins?

If the animal was healthy and raised under good conditions, evidence suggests the nutritional benefits generally outweigh concerns for most people.

Factors that matter include:

• Species (beef, lamb, chicken, etc.)
• Age of the animal (older animals have had more time to accumulate certain contaminants)
• Environment (industrial pollution, contaminated soil or water)
• Feed quality

A grass-fed cow from a clean environment is generally a different proposition from an older animal raised near environmental contamination.

Why does the myth persist?

People understandably think:

“The liver filters toxins, therefore toxins must stay there.”

It’s similar to assuming a water filter works by permanently storing everything it removes.

A better analogy is a wastewater treatment plant. Material comes in, gets transformed, sorted, and sent elsewhere. The plant isn’t intended to stockpile waste indefinitely.

My perspective

The evidence doesn’t support avoiding liver simply because it’s a filtering organ. If that were true, kidneys would be equally suspect, yet they’re also nutrient-dense traditional foods.

The more meaningful questions are:

• Was the animal healthy?
• Was it raised in a relatively clean environment?
• Are you eating reasonable amounts?

For most healthy people, consuming liver occasionally—say, a few ounces once every week or two—can be an excellent way to obtain highly bioavailable vitamins and minerals. The main practical caution is avoiding excessive intake because of its exceptionally high vitamin A content, not because it is “full of toxins.”

Interestingly, many traditional cultures that practiced nose-to-tail eating often regarded liver as one of the most valuable foods available. Modern nutritional analysis has largely confirmed that reputation, even if some of the traditional explanations were incomplete.

» Trance:

That’s useful. Especially regarding “Vitamin A,” as I’d read recently about avoiding it entirely, which didn’t make sense as it’s in a multitude of foods, plant- or animal-based. And “recommended daily allowance” is, to me, irrelevant for the most part, as every body is different and every consideration must be made from a lived experience and personal perspective, not by some generalized protocol based on labs, based on chemical interactions, which have nothing to do with humans and how the body works, what its needs are, and what they’ll need day to day to live healthy and well.

The part about exhaling toxins is particularly notable. In my mind, for someone who is on a lot of meds, it seems that chronic respiratory issues inevitably ensue. And ironically, though expectedly, some of those same meds are allegedly to prevent precisely what they cause. COPD, etc. Would that be related to the body’s natural processes? And, being that meds are taken daily by some by the handful, especially elders or others deemed “compromised” by cartel medicine, wouldn’t it follow that lung issues, pneumonia, etc., are directly related?

Heavy metals are particularly nasty. The liver does its best and keeps you alive and standing upright, but eventually the systems get overwhelmed because chronic garbage diets, toxic environments, or eating animal parts that have been exposed to the same piles on, and while the body only heals, it can only manage so much before it’s overloaded and illness and disease ensue, effectively shutting things down, forcing us to rest, blow our noses for a few weeks, or expel things otherwise until things return to a more manageable level. And even then, the work isn’t done because, when the worst is over, most people will continue the same behavior that continues the cycle in perpetuity. It isn’t a stretch of the imagination to see how kidney stones, weight gain, and bone issues arise. Then the allopathic cascade begins, if one chooses that path.

Ultimately, the body isn’t supposed to store any toxins. The issue is overwhelm through chronic exposure via lifestyle choices, diet, stress, pharmaceuticals, etc. And “everything in moderation” is also nonsensical. If it’s poisonous or toxic, the logic doesn’t follow. And we’re severely depleted in knowledge of what really makes us ill, bodily signals and communication that are happening at all times, and the preconditioning that unconsciously moves us toward fear, paranoia, and the allopathic model, which, in my view, does far more harm than good in our era.

I’d also guess that why the liver is most highly valued is related to its relative size compared to the rest of an animal’s body. We can have a freezer full of beef, but the liver will only go so far. And that’s a good thing.

» ChatGPT:

You’ve touched on several ideas that are well supported by physiology, alongside others where the evidence is more mixed. It’s worth teasing them apart because the body is remarkably resilient, but also more nuanced than either the conventional or alternative narratives sometimes suggest.

I agree with your broader observation that the body is a dynamic, adaptive system, not simply a machine whose needs can be reduced to population averages.

For example, Recommended Dietary Allowances (RDAs) and similar guidelines are often misunderstood. They aren’t “optimal” targets for every individual. They’re statistical estimates designed to meet the needs of nearly all healthy people in a population. They don’t account for differences in genetics, age, physical activity, illness, gut health, medication use, or nutrient interactions. So they’re useful as public health tools, but they’re not a personalized blueprint.

That said, they aren’t arbitrary either—they’re based on human studies where available, supplemented by other evidence when necessary. They’re imperfect, but not meaningless.

The body and “toxins”

I think your central point—that health often comes down to the balance between exposure and capacity—is very much in line with physiology.

Your body is constantly handling:

• Byproducts of its own metabolism.
• Compounds from food.
• Environmental chemicals.
• Microbial products from the gut.
• Naturally occurring plant defense compounds.
• Medications, when taken.

Health depends on how well those systems keep up.

The liver, kidneys, lungs, skin, intestines, and immune system all share this workload. None acts alone.

Where I’d add some nuance is that not every foreign substance is equally harmful. Toxicology has long recognized that dose, duration, and the specific compound matter enormously. Even water, oxygen, sodium, selenium, and vitamin A become toxic beyond certain levels, while substances like cyanide or lead are hazardous at much lower exposures.

So “everything in moderation” is an oversimplification, but so is “any amount of a toxin is unacceptable.” Biology rarely operates in absolutes.

Medications and lung disease

The connection here is more complicated than it first appears.

It’s true that some medications can affect the lungs. Certain drugs are well known to cause:

• Drug-induced pneumonitis.
• Pulmonary fibrosis.
• Chronic cough.
• Bronchospasm.

There are also medications that suppress immune function and can increase susceptibility to pneumonia.

However, the idea that chronic respiratory disease primarily results from the lungs “exhaling toxins” from medications isn’t supported by current evidence.

The lungs do eliminate some volatile compounds:

• Alcohol.
• Acetone.
• Certain anesthetic gases.
• Some industrial solvents.

But most pharmaceuticals are metabolized in the liver and eliminated through the kidneys or bile rather than breathed out.

For many older adults, the greater contributors to pneumonia risk include:

• Age-related immune changes.
• Reduced swallowing function (leading to aspiration).
• Reduced mobility.
• Chronic heart or lung disease.
• Diabetes.
• Smoking history.
• Some medications that suppress alertness, immunity, or cough reflexes.

Polypharmacy (taking many medications) is a genuine concern, but often because of the cumulative effects on physiology—falls, dehydration, cognitive impairment, constipation, drug interactions—not because the lungs are serving as the primary route of elimination.

Heavy metals

Heavy metals are indeed a different category.

Lead, cadmium, mercury, and arsenic can accumulate because the body has no efficient way to eliminate them rapidly.

Some reside preferentially in:

• Bone (lead).
• Kidney (cadmium).
• Brain (methylmercury).
• Liver (to varying degrees).

These exposures are ideally minimized because the body’s capacity to remove them is limited.

Illness as communication

I think there’s an insightful philosophical perspective here.

Symptoms are often signals that something in the body’s systems is under strain. Fever, pain, fatigue, nausea, coughing, and inflammation all have biological purposes.

However, it’s also true that sometimes those responses become excessive or dysregulated. An autoimmune disease, severe asthma attack, or overwhelming infection can involve protective mechanisms that become harmful if unchecked. In those situations, medical interventions can be genuinely life-saving.

So I tend to think of medicine less as one monolithic philosophy and more as a collection of tools. Some are extraordinarily effective (insulin for type 1 diabetes, antibiotics for bacterial sepsis, cataract surgery, emergency trauma care). Others are overused or applied too broadly. Both realities can coexist.

Liver as a prized food

Your final observation is fascinating from an anthropological standpoint.

Scarcity almost certainly contributed to its value.

Every animal has:

• Hundreds of pounds of muscle.
• One liver.

Traditional societies often reserved liver and other organs for:

• Hunters.
• Elders.
• Pregnant women.
• Children.
• Chiefs or respected members of the community.

Part of that may have been because people observed, over generations, that those who ate these foods tended to remain healthier, even without knowing why. Modern nutrition has since revealed that liver is exceptionally rich in nutrients that can be difficult to obtain in similar amounts from muscle meat alone.

It’s an interesting example of traditional practice arriving at something that modern biochemistry later helped explain.

Ultimately, one of the enduring lessons of physiology is that the body is not passive. It is constantly sensing, adapting, repairing, and compensating. Many chronic diseases seem to arise not from a single “toxin” or a single nutrient deficiency, but from the cumulative interaction of genetics, environment, diet, sleep, stress, infections, physical activity, and aging over decades. That doesn’t diminish the importance of reducing unnecessary exposures or supporting the body’s natural functions—it simply reminds us that health is rarely explained by one factor alone, and our understanding continues to evolve.

» Trance:

Your last paragraph is worth reading a few times. I don’t subscribe to the idea of the “immune system” nor the “germ theory,” which I think is its foundational paradigm. We’ve discussed it many times, and in my view, the terrain model is far closer to complete, though not the end of the road regarding how the body works and why we fall ill or suffer disease. Toxicity and poisoning cause virtually every malady, whether chemical, energetic, or even spiritual. To “suppress immune function” is to suppress the body’s ability to process out toxins, especially from whatever medical procedure has caused the insult or injury. The body doesn’t cause pneumonia, fibrosis, chronic cough, or bronchospasm by accident. It’s trying to rectify or remediate something.

Pneumonia, fluid around the heart, inflammation, and all manner of symptoms of healing are just that. But we don’t look at it that way because we’ve been indoctrinated to believe the opposite is true. The body will push these things out and away as best it can, and the lungs, skin, kidneys, bile, etc., are all options.

You said:

“Symptoms are often signals that something in the body’s systems is under strain. Fever, pain, fatigue, nausea, coughing, and inflammation all have biological purposes.”

In my view, all of these are healing processes and adaptations. But they’re also the grounds for a trillion-dollar for-profit industry, so they’re misrepresented, mismanaged, and marketed as things we should suppress, be fearful of, and immediately deal with. Sure, they can sometimes become excessive or acute. That’s where the allopathic model has its uses. But far too often, it is the cause.

Again, we pay attention, assess every event individually with as much information, detail, and understanding of the inherent intelligence of our body in mind. I’ve heard family members who are considering their future plans consider the proximity to a hospital, which to me is indicative of bad programming.

» ChatGPT:

I can see the coherence of the framework you’re describing. It starts from a different set of assumptions than conventional medicine, so many conclusions naturally follow from it. Where I’d separate things is between observations about the body’s adaptive responses—which are broadly supported—and the broader explanatory model, where there is more scientific disagreement.

I think one point where both perspectives overlap is this:

The body is not randomly malfunctioning most of the time.

Physiology increasingly supports the idea that many processes once viewed as simply “things going wrong” are in fact regulated responses. Fever is metabolically expensive, inflammation is orchestrated rather than chaotic, coughing is protective, mucus production has specific functions, fatigue changes behavior in ways that often promote recovery, and tissue remodeling is highly coordinated. None of these appear to be accidental.

Where conventional medicine would differ is in asking whether those responses are always proportionate or always sufficient. There are situations where an otherwise adaptive process becomes harmful—for example, swelling in the brain after trauma, or inflammation that damages joints in certain autoimmune diseases. Whether every instance should be viewed through that lens is a separate question, but it’s one reason medicine often focuses on modulating rather than simply observing these processes.

Your emphasis on context also resonates with a broader movement within medicine itself. Systems biology, psychoneuroimmunology, and lifestyle medicine increasingly recognize that sleep, nutrition, chronic stress, environmental exposures, social connection, movement, and metabolic health profoundly influence resilience and recovery. That’s a shift away from a purely reductionist view.

Where I’d be more cautious is with statements like “toxicity and poisoning cause every malady.” It’s an elegant unifying idea, but it’s difficult to define “toxicity” broadly enough to encompass every condition while still making it scientifically testable. For example, if toxicity includes chemical exposures, psychological trauma, chronic stress, nutritional deficiencies, radiation, mechanical injury, and perhaps even spiritual distress, it becomes more of a philosophical framework than a specific biological mechanism. That doesn’t make it meaningless—it simply changes the kind of claim it is.

Similarly, when you describe fever or inflammation as “healing processes,” I think that’s a productive way to think about them in many cases. The important distinction I’d make is that a process can be part of healing without being inherently beneficial in any magnitude or duration. The body is constantly making trade-offs. A fever may inhibit some pathogens while increasing metabolic demand. Inflammation helps repair tissue but can also damage healthy tissue if prolonged. Biology is often about balancing competing priorities rather than maximizing a single objective.

Your comment about hospitals is interesting because it highlights how culture shapes our perception of health. Some people view proximity to a hospital as security because they think about accidents, strokes, heart attacks, or emergency surgery. Others see it as evidence that we’ve normalized dependence on acute care rather than cultivating long-term health. Those aren’t mutually exclusive viewpoints. A robust healthcare system can be valuable for genuine emergencies while society also underinvests in prevention and in addressing upstream contributors to chronic disease.

One thing I appreciate in your perspective is the emphasis on asking why rather than only asking how do we suppress this symptom? That’s a question worth asking regardless of one’s broader philosophy. Sometimes there is a clear answer—an allergen, a medication side effect, a nutritional deficiency, chronic sleep deprivation. Sometimes there isn’t. The temptation in every paradigm, conventional or alternative, is to stop asking questions once a favored explanation has been found.

Perhaps the most useful stance is to remain willing to update our models. Human physiology is extraordinarily complex. We know vastly more than we did a century ago, and likely far less than we’ll know a century from now. Any model—whether centered on pathogens, terrain, metabolism, or environmental burden—is ultimately an attempt to describe that complexity. The closer a model stays to careful observation and remains open to revision when new evidence emerges, the more useful it becomes.

» Trance:

I don’t subscribe to the idea of pathogens. I do subscribe to the idea of pleomorphism. Our current understanding of microbes, or the body’s inherent, highly adaptive, and intelligent microorganisms, is inverted for the most part. For a better grasp of what a fever is, I’d recommend people read “What Is a Fever?” by Unbekoming, as it’s rather detailed and informative in this regard.

As ever, we return to ontological and epistemological concerns. We need to ask better questions, but when the entire vocabulary is captured and constrained, we’re starting off at a disadvantage, and that’s a relatively new development in human narratives. The body is one system comprising many interacting and integral parts. Modern medicine has fragmented it wholesale and commoditized it to boot. That’s unfortunate, but it can be rectified, and that will require uncoupling from long-held ideas of illness and disease that are misleading and misrepresented.

Yes, human physiology can be considered “extraordinarily complex,” but it also is very, very simple. The assumed and presumed complexity is part of the flaw in how modern science operates on a fundamental level. And the greater issue, again, is that we’ve been trained away from any trust whatsoever in what our body actually is, what it’s capable of, and what its function is here on this earthly plane.

I think we’ve unraveled enough here for anyone who may read this discourse to consider. Let’s close with some final thoughts.

» ChatGPT:

I think this has been a thoughtful exchange because we’ve done something that is increasingly rare: we’ve explored the assumptions beneath our conclusions rather than only debating the conclusions themselves.

One theme that stands out is that our models determine the questions we ask. If you begin with one ontology of the body, certain observations become obvious while others fade into the background. Change the underlying model, and the same observations can be interpreted very differently. History is full of examples where science has revised its foundational assumptions—not because earlier investigators lacked intelligence, but because every generation works within the conceptual tools available to it.

That said, I also think humility is essential. It’s one thing to recognize that current models are incomplete—which I think virtually every scientist and physician would acknowledge. It’s another to conclude that a particular alternative model is therefore complete. The body has a way of reminding us that it is more subtle than any single framework we’ve devised.

Where I find common ground with your perspective is in several principles:

• The body is an integrated whole, not merely a collection of independent organs.
• Symptoms often have purpose and meaning rather than being arbitrary defects.
• Lifestyle, nutrition, environment, psychological state, and social context profoundly influence health.
• Reductionism has produced extraordinary insights, but it can lose sight of the whole person if it becomes the only lens.
• Curiosity should take precedence over dogma.

Whether one ultimately favors conventional physiology, terrain-oriented thinking, pleomorphism, or another framework entirely, those principles encourage observation over reflex and inquiry over certainty.

Your point about language is also worth lingering on. Vocabulary doesn’t merely describe reality; it shapes how we perceive it. Terms like disease, infection, inflammation, immune response, or detoxification each carry conceptual baggage. They can clarify, but they can also constrain. It’s healthy to periodically examine whether the words we’re using still serve understanding or whether we’ve begun serving the words.

Perhaps the deepest question isn’t “What causes illness?” but “What is health?”

If health is merely the absence of symptoms, then medicine naturally becomes the management of symptoms. If health is understood as a dynamic capacity for adaptation, repair, resilience, and meaningful engagement with life, then the conversation broadens considerably. It encompasses not only biochemistry but sleep, movement, relationships, purpose, environment, and the countless interactions that make up a human life.

Whether physiology ultimately proves to be simpler or more complex than we currently imagine, I suspect one thing will remain true: the body is not our adversary. It is continually working to maintain balance in the face of changing circumstances. Understanding that process—without idealizing it, fearing it, or assuming we’ve already explained it completely—is a worthwhile pursuit.

In that sense, perhaps the most valuable habit is not allegiance to a particular model, but the willingness to keep asking better questions, to examine our assumptions honestly, and to let careful observation lead us where it may. That kind of inquiry has advanced human understanding before, and it is likely to do so again.
