Cadmium
Exists in all foods as a nutritive trace mineral until heat severs its ionic bonds, at which point it becomes a free-radical toxin that accumulates in kidneys, brain tissue, and nervous system, driving cancer and neurological dysfunction.
Cadmium is one of the heavy metallic minerals that Aajonus Vonderplanitz identified as a significant source of toxicity in the human body, particularly in its role as a contributor to cancer. He understood cadmium, like all metallic minerals, as a substance that is both necessary and dangerous depending entirely on its form and context. In trace amounts, ionic, enzymatically bound, and accompanied by the full complement of other minerals and nutrients, cadmium participates in the functioning of the nervous system and brain alongside lead, mercury, copper, gold, and other conductors of electricity and light. The brain and nervous system rely on metallic minerals precisely because those minerals reflect light and conduct electricity, which is how neurological communication operates. Cadmium in a raw, living food exists in proper ionic union with other elements and is not toxic in that state.
The problem arises when cadmium is fractionated from its ionic bonds through heat. Cooking food at any significant temperature destroys the enzymatic and ionic relationships that keep metallic minerals like cadmium bound and functional rather than free-radical and damaging. Once fractionated, cadmium becomes what Aajonus called a free radical, a cauterized metallic particle that the body cannot easily integrate, that accumulates in tissues, and that produces corrosive, acidic damage to the cells surrounding it. He extended this principle to all forms of food preparation that involve heat, including the steeping and boiling of Chinese medicinal herbs, which he stated "completely frees the cadmium mercury and lead and a poison thimerosal," making even plants with medicinal reputations a source of metal poisoning when cooked.
Sources of Cadmium Exposure
Aajonus identified multiple routes by which cadmium enters the body in its toxic, cauterized form. The most broadly discussed was cooked food generally, since all foods contain trace amounts of cadmium and cooking liberates those minerals from their ionic bonds. Canned foods were named as a significant source of metal poisoning in the general population, with the metals from cans leaching into the food through moisture contact and heat.
Beyond dietary exposure, he pointed to occupational and environmental sources. Dyes were specifically named: yellow dyes, including dye numbers such as yellow 16, 13, 5, and 7, were identified as containing cadmium as the colorant. Aajonus stated directly that cadmium is "what makes it yellow" in those food and industrial colorants, and described it as "a heavy metal that causes kidney cancer." He advised that anyone working with yellow or blue dyes should wear thick gloves and an industrial-grade mask, specifying cobalt and cadmium as metals that vaporize during use, meaning they are inhaled and absorbed transdermally even during routine craft or industrial work.
Body paint clays used by certain tribal populations were also mentioned as a historical source. He described certain yellowish clays with high cadmium content being used for body paint, with the result that those populations developed pancreatic cancer. This was presented as evidence that cancer is always traceable to a specific pollutant or toxic mineral, even in pre-industrial or traditional contexts, rather than to diet alone.
The combination of mercury, cadmium, and lead was specifically flagged as a synergistic toxicological situation. Aajonus cited research suggesting the combined effect of these three metals was being investigated and that the interaction was synergistic rather than merely additive, meaning the combined toxicity could be a hundred or even a thousand times greater than any one metal alone.
Cadmium and Kidney Cancer
The most detailed and repeatedly stated connection Aajonus made regarding cadmium was its role in producing kidney cancer. He described a patient named Jeff whose father had kidney cancer, and instructed Jeff to take a tissue sample from the kidney and have it analyzed at a laboratory for heavy metals. The result came back showing high levels of cadmium. Aajonus then looked up cadmium's known associations with cancer and confirmed that kidney cancer is one of the primary cancers produced by cadmium toxicity. He cited this case in multiple contexts as a demonstration of his broader principle: that cancer always has a specific toxic cause identifiable through laboratory analysis of the cancerous tissue.
He stated his practice explicitly: "anytime I want to know why my patient has cancer, I take some of their vomit, their diarrhea, if they're having diarrhea at the time, or some of that tissue that has cancer in it, or the actual tumor, take a piece of that and have it analyzed." The cadmium case with Jeff's father was his central example of how this diagnostic approach works.
Cadmium and Pancreatic Cancer
In addition to kidney cancer, Aajonus connected cadmium to pancreatic tumors. He described another patient whose father had pancreatic cancer and who, following the same protocol of tissue analysis, found high levels of manganese in the pancreas rather than cadmium. However, in discussing this case, Aajonus grouped cadmium and manganese together as examples of the category of toxic minerals whose internet-searchable cancer profiles correspond to tumors of the kidney and pancreas. He stated: "if you look on the internet and you find out a toxic level of manganese and also cadmium, most of them apply to tumors of the kidney and pancreas."
Cadmium's Effects on Neural Tissue
Aajonus described the brain and nervous system as the primary destination for free-radical metallic minerals, including cadmium, because those systems use metallic minerals for their basic functions of conducting electricity and reflecting light. He estimated that "almost 80% of all the heavy metals in your body are in the brain and nervous system." Cadmium was named alongside mercury, lead, aluminum, and thallium as the specific metals that accumulate there when released as free radicals from cooked food or other toxic exposures.
Once stored in the brain and nervous system, these metals cause misfiring of synapses, blockages, and current disruptions in axons and ganglia. The buildup interferes with neurological communication and produces what Aajonus described as an enormous range of downstream consequences, from behavioral dysfunction particularly in children to the broader degenerative conditions associated with metal-polluted nervous systems.
He noted that while mercury, aluminum, lead, cadmium, and other metals in their natural ionic form are the very substances the brain and nervous system require to function, once they are cauterized by heat they shift from assets to free radicals. The distinction between nutritive trace metallic minerals and toxic free-radical versions of the same elements was foundational to his entire framework on metal toxicity.
Cadmium Elimination Through Gums
When the brain and nervous system begin clearing accumulated metallic free radicals, Aajonus described the primary exit routes as the sinuses, tear ducts, earwax, gums, tongue, and salivary glands. Cadmium, alongside mercury, thallium, lead, and aluminum, exits predominantly through the gums. As these metals travel out through the gum tissue, the body binds them with alkalinizing minerals, principally calcium, phosphorus, magnesium, and potassium, producing what is visible as dental plaque. The plaque is therefore not a pathogen or a sign of poor hygiene in Aajonus's framework; it is the body's mineral containment system for acidic, toxic metals being discharged from the brain.
The problem with this containment system in people eating cooked diets is that the alkalinizing minerals in those diets are themselves cauterized and therefore functioning at greatly reduced capacity. He specified that calcium loses approximately 50% of its alkalinizing ability at 141 degrees Fahrenheit, the standard pasteurization temperature, and that phosphorus begins transforming as early as 98 degrees and loses essentially all alkalinizing ability by 105 degrees. With compromised alkalinizing minerals attempting to neutralize highly acidic metals like cadmium, the plaque cannot fully buffer the toxic effect, and the metals eventually work through and begin dissolving the dentine, causing cavities. He stated emphatically that bacteria does not cause cavities; the heavy metals from vaccines, cooked foods, and other sources do the damage, and bacteria only arrives afterward to consume the already-damaged dentine cells.
Cadmium and Occupational Exposure
Aajonus addressed a specific case in a workshop where a participant revealed they were using dyes in their work. Upon learning this, he immediately attributed the metal poisoning visible in that person's brain (evidenced through iris analysis) to the cadmium and cobalt in the dyes. He stated: "if you're using any kind of yellow or blue dye, you've got cobalt and cadmium. Definitely." He instructed the individual to use very thick gloves when continuing to work with the dyes and to wear a proper industrial mask, specifying that "especially cobalt and cadmium, they will vaporize," making inhalation a primary route of absorption during dye work.
He also discussed the general category of metalworking occupations as sources of heavy metal exposure, including silver jewelry making, a trade in which silver alloys may contain mercury, thallium, and other metals that vaporize when heated over a Bunsen burner. While this particular extended case involved thallium rather than cadmium, it demonstrates the framework he applied to all occupational metal exposures: the vaporized metals are inhaled continuously, bypass normal digestive filtering, enter the body directly through the lungs and skin, accumulate faster than the body can discharge them, and eventually cause cancer at concentrations that are multiples of the lethal dose.
Light Berries Chelate Cadmium
Aajonus distinguished between different fruits and their specific affinities for different metals during chelation. He described light-colored berries as having a tendency to draw out lighter metals, specifically naming iodine, oxidized iron, and cadmium as the metals that light berries preferentially bind and pull from the body. He contrasted this with dark berries, which he described as more effective for pulling out "dark, heavy gray and black metals," with blueberries first, blackberries second, boysenberries third, and dark mulberries fourth in order of effectiveness for those heavier metals.
The implication for cadmium is that lighter berries are the appropriate chelation tool for that particular metal, although the sources do not specify which light berry is most effective or provide a precise protocol for cadmium specifically through berry consumption. Cadmium was named as part of the category of "lighter metals, lighter in color" that respond to light-colored berry consumption.
Fat Buffers Cadmium Toxicity
Consistent with his treatment of all heavy metal toxicity, Aajonus emphasized that fat is the body's primary defensive tool against cadmium and other free-radical metallic minerals. He noted that when meat is consumed raw, 98 percent of whatever toxicity exists in it, including metallic contamination, passes through the body "contained within relatively unaltered fat molecules," meaning the fat envelops the toxin and carries it out rather than allowing it to deposit in tissue. This was the result he reported from his own testing.
When fat is absent or insufficient, free-radical metals including cadmium have nowhere to bind and migrate directly to the brain and nervous system. He traced the increased incidence of metal toxicity in the brain to the aggressive low-fat dietary paradigm of the preceding decades, arguing that defatted food leaves no buffer for the metals released by cooking and that those metals travel immediately to the brain precisely because the brain operates on metallic minerals and actively absorbs them.
Raw cream, butter, and coconut cream were all mentioned in the context of protecting against or assisting the elimination of heavy metals. Raw cream in particular was recommended as a one to two tablespoon dose to be consumed before drinking vegetable juices that pull heavy metals, to prevent the metals from circulating freely in the blood before being bound and excreted.
Cadmium Contamination in Cooked Foods
Aajonus made the point clearly and repeatedly that cadmium, along with lead, arsenic, mercury, and other metallic minerals, exists naturally in all foods. He stated: "All foods have metals. They have arsenic. They have lead. They have cadmium. All foods contain all of those elements. They are only toxic when they are not enzymatically, nutrient, and ionically bound." The destruction of those bonds through cooking is what transforms cadmium from a nutritive trace mineral participating in biological function into a free-radical toxin that accumulates in tissue and causes disease.
This framing was the basis of his objection to cooked Chinese medicinal herbs specifically. He stated that it does not matter what a person eats, including medicinal herbs intended to support health, if those substances are steeped or cooked, because the heat "completely frees the cadmium mercury and lead," making the preparation a source of metal poisoning regardless of the therapeutic intention behind it.
Laboratory Diagnosis and Cancer
Aajonus described a systematic approach to identifying the cause of any cancer through laboratory analysis of the relevant tissue. The cost of these tests was significant; he mentioned one eight-phase tumor analysis costing $2,300 or more. He used vomit, diarrhea, tumor tissue, or organ samples from deceased patients to identify the specific heavy metal or industrial contaminant responsible for each cancer. Cadmium emerged from this methodology as the identified cause in kidney cancer cases he personally investigated.
He also described collecting vomit samples during vomiting episodes, specifying that the third, fourth, or fifth vomit of a vomiting episode gives the most useful picture of what metals are being discharged, because by that point the body is clearing material from deeper stores rather than just recent intake. He noted he could use all the samples but that the later ones in a vomiting series provide the clearest diagnostic window.
He stated his general principle from this body of work: "It's usually a heavy metal or a contaminant" that is found in cancer tissue. Cadmium, manganese, and thallium were the metals he named from specific cases he personally investigated.
Hair Analysis Findings
Aajonus referenced thousands of hair mineral analyses performed to measure mineral content in the body. He reported that most showed unnaturally high levels of lead, iron, cadmium, and other toxic metals. He cited this data as evidence for the widespread nature of metal poisoning in the general population from cooking food in metal vessels, eating canned foods, and environmental contamination, rather than from any one isolated source.
