Environmental Toxins

Whether something is occupying the seat a nutrient was meant to sit in. This is a tier-one entry not because everyone needs a full toxic-element workup, but because almost nobody is offered one at all -- and a standard panel is silent on it. Deficiency gets investigated. The other half of the equation usually does not.

Typical range: There is no single number here. Blood lead and mercury reflect recent exposure rather than what is stored in tissue; a normal blood level does not rule out a body burden accumulated over years. Aluminium and glyphosate are not on any standard panel at all. That absence is the point of this entry -- it is a gap in the usual workup, not a result.

Food first: The protective pattern is unglamorous and consistent: sufficient minerals so there is no vacancy to fill, adequate protein for the conjugation pathways, sulphur-bearing vegetables such as brassicas, garlic and onions, and enough fibre to carry conjugated compounds out rather than allowing reabsorption. Iodine sufficiency specifically, because the halogen competition is at a single named door. Filtered water, and reducing the intake side wherever it is identifiable.

The level of a toxic heavy metal with no known safe or beneficial level in the body, accumulating in bone and affecting the brain, kidneys, and cardiovascular system with chronic exposure.

Typical range: Standard: under 3.5 mcg/dL is the current CDC reference/action level for adults -- there is no optimal nonzero level; lower is always better.

Food first: Ensure adequate dietary calcium, iron, and vitamin C, especially in children and pregnant women (the highest-risk groups for lead's neurodevelopmental effects).

When to see someone: Nutritional strategies reduce absorption of *ongoing* low-level exposure -- they do not treat significant lead toxicity, which requires medical evaluation and, in some cases, chelation therapy. Any meaningfully elevated lead level needs a source investigation, not just a supplement response.

The level of a toxic heavy metal, most commonly elevated in adults from eating fish/seafood higher on the food chain.

Typical range: Standard: under 10 mcg/L (whole blood) is a commonly used general-population reference, though this varies by lab and by whether inorganic vs. methylmercury is being measured; there is no optimal nonzero level.

Food first: Choose lower-mercury fish (salmon, sardines, shrimp, cod) over high-mercury species (swordfish, king mackerel, shark, bigeye tuna) to get omega-3 benefits without excess mercury load; adequate selenium intake is theoretically protective but shouldn't be a reason to eat high-mercury fish liberally.

When to see someone: Elevated mercury in pregnant women or young children warrants dietary source investigation and possibly medical guidance given fetal/childhood neurodevelopmental sensitivity; don't rely on selenium supplementation as a way to "offset" ongoing high-mercury fish consumption.

Serum aluminum is the standard test, and what it means depends almost entirely on kidney function. With normal kidneys the body clears aluminum efficiently, so serum levels are usually low and not very informative about tissue burden. Urine aluminum reflects recent exposure and excretion capacity and is used in research protocols.

Typical range: There is no meaningful optimal level -- aluminum has no biological role. The marker becomes genuinely actionable in one specific population: people with impaired kidney function, especially dialysis patients, where aluminum is renally cleared and dialysis does not remove it efficiently. Periodic monitoring is standard of care there.

Food first: Silicon-rich mineral water, adequate magnesium, and enough fluid to support normal kidney function.

A serum or plasma panel that sums seven to nine individually measurable PFAS compounds -- PFOA, PFOS, PFHxS, PFNA, PFDA, PFUnDA and MeFOSAA -- rather than reporting "PFAS" as one number. There are thousands of these chemicals and only a handful can be measured and interpreted reliably. They are called forever chemicals because the carbon-fluorine bond barely breaks down, so they persist in the body for years.

Typical range: The National Academies (NASEM, 2022) published numeric action tiers, which is unusual for a toxin panel: under 2 ng/mL summed is usual standard of care; 2 to under 20 ng/mL means counselling on exposure reduction plus screening for dyslipidemia and pregnancy hypertension; 20 ng/mL and above adds thyroid testing, and kidney assessment over 45.

Food first: Fiber-rich whole foods, filtered drinking water, and reduced exposure at source -- PFAS-free cookware and food packaging where practical, and care with fish from known-contaminated waters.

When to see someone: Any product marketed as a PFAS detox should be treated skeptically -- the evidence-backed list is short: donation, prescription bile-acid binders under supervision, dietary fiber, and removing the exposure source.

This marker sits in Transform -- the cofactors enzymes need to turn fuel into usable energy.

Hair tissue mineral analysis (HTMA) measures mineral and trace-element concentrations in a hair sample, marketed as a window into longer-term tissue mineral status; the functional model sometimes references whole-blood or hair testing as a supplementary way to assess mineral patterns beyond a standard serum panel.

Typical range: No standardized reference ranges exist across labs; each commercial HTMA lab uses its own ranges and often its own proprietary "ratio" interpretive system.

Food first: N/A.

When to see someone: Don't make major supplementation decisions (especially involving iron, copper, or high-dose minerals) based solely on an HTMA result -- confirm with standard serum/blood testing, since HTMA's inter-lab reliability for general mineral status is weak.
