Feces
Categorized as dangerous waste by modern medicine, but in healthy animals eating raw diets it is simply partially digested food cycling through the ecological chain. Toxicity in feces reflects the diet that produced it, not feces itself.
Feces and excrement, in Aajonus Vonderplanitz's framework, are fundamentally misunderstood substances that modern civilization has categorized as dangerous waste when in fact they are, in most natural circumstances, partially digested food material useful to other organisms and in specific conditions useful to humans themselves. The foundational reorientation Aajonus insisted upon is that fecal matter is not inherently toxic. It is only when a creature has been consuming cooked food, processed chemicals, preservatives, pharmaceuticals, or industrial contaminants that its excrement becomes genuinely poisonous. In healthy animals eating their natural raw diets, feces is simply undigested or incompletely digested food that becomes nourishment for the next level of the ecological chain.
The conventional medical insistence that humans must defecate daily, that anything less signals constipation, and that fecal matter is categorically dangerous waste, was something Aajonus regarded as systematic miseducation. He documented cases of people on the Primal Diet who went five, six, or seven days between bowel movements and were not constipated in any meaningful sense. Their bodies were simply absorbing and utilizing everything consumed, leaving almost nothing to discard. He considered that state a sign of exceptional digestion, not pathology. His definition of true constipation was narrow and specific: a hard, immovable mass, roughly the size of a fist, lodged in the bowel and unable to pass. Everything else that gets called constipation he reframed as either excellent nutrient absorption or a bacterial deficiency problem.
Understanding feces correctly, in Aajonus's view, requires understanding the entire bacterial architecture of the digestive tract. Fecal matter is 60 to 80 percent bacteria by composition. That bacteria is not contamination. It is the primary mechanism by which feces becomes soft, movable, and comfortable to pass. Without adequate bacterial populations in the colon, feces shrinks to marble-sized pellets with the texture of granite that lacerate the rectum on exit. The bacteria, principally E. coli, feed on the fecal matter moving through the colon, sponge it out, swell it, and render it passable. The entire relationship between humans and their excrement is therefore a bacterial story.
Composition and Formation of Feces
Feces forms as the residue of food that was not fully digested during the 24-hour transit through the digestive tract. Aajonus described the process beginning in the small intestine, where hydrochloric acid and bile break down large food particles into smaller molecules that bacteria can infiltrate and consume. The bacteria's secretions, urine, and feces are what the intestinal walls actually absorb as nutrition. What remains after that 24-hour process, the portion the bacteria could not fully process, becomes fecal matter.
In the colon, E. coli and related bacteria perform the final stages of this process. They break down protein and fat molecules to the finite size required to feed the brain and nervous system. They also manufacture approximately 80 percent of the B vitamins present in the body and release them from animal products being digested. Without functional E. coli, only 20 percent of dietary B vitamins would be released. E. coli additionally synthesizes amino acids that serve as a backup supply for the immune system, and its byproducts have been demonstrated in university research contexts to dissolve brain tumors and other tumors.
Fecal matter in the sigmoid colon is where the body performs its final extraction. The sigmoid colon holds fecal matter while the body draws out the remaining digestive fluids, absorbing every last nutrient it can. The more bacterial activity present, the less the body needs to desiccate the feces to recover nutrients. The less bacterial activity, the more thoroughly the body dries out the fecal matter, pulling every molecule of usable fluid from it, which produces rock-hard stool.
Bacteria In Feces Functions
Aajonus placed the bacterial population of the colon among the most important in the entire body, ranking it alongside the lymphatic system as a primary immune environment. E. coli was the centerpiece of this population. He considered the widespread fear of E. coli to be one of the most damaging pieces of medical misinformation in circulation, because destroying E. coli through enemas, colonics, antibiotics, or alkalizing foods strips the nervous system of its primary nutritional support pathway and sends people into depression, emotional instability, and cognitive decline.
The byproduct identified as "varicoxin" from E. coli was cited in relation to work at the University of Toronto and the Hospital for Sick Children of Toronto, where this substance was being used to dissolve human brain tumors within two to five days. Yale University was separately cited as using salmonella to shrink and dissolve tumors. These examples were Aajonus's way of demonstrating that microbes universally feared and associated with dangerous feces were in fact doing therapeutic work that conventional medicine simultaneously condemned and quietly utilized.
Green feces was a specific diagnostic signal Aajonus identified. If feces is green, E. coli is not functioning. Green feces indicates that too many non-digestible vegetable products are passing through, that the body is secreting excessive alkaline fluids, and that colon bacteria are severely compromised. The corrective response he suggested was filtering vegetable juice more thoroughly to prevent undigestible vegetable matter from reaching the colon.
What Healthy Feces Looks Like
Aajonus described what truly healthy feces would look like by reference to wild carnivores on their natural diets. A wild dog, wolf, or cat eating its natural prey produces feces containing almost exclusively hair and some hide. Everything else, bone, cartilage, sinew, tendon, and all meat, is fully digested. That feces turns white as it oxidizes and disintegrates into dust, essentially returning to earth. Aajonus noted that his own feces, despite years on the Primal Diet, was still too toxic to turn white in this way, which he offered as a measure of how contaminated modern humans remain even when eating optimally.
For a person on the Primal Diet who is digesting efficiently, fecal matter should be small in volume, narrow, and relatively soft. Very small quantities indicate excellent absorption rather than pathology. Aajonus repeatedly described people alarmed at producing only a few inches of thin stool after days without a bowel movement, and he consistently reassured them that this was the body operating at high efficiency. He also noted that feces could smell of metal or a combination of rot and metal when the body is discharging stored poisons, and that most bowel movements would not smell strongly rotten if colon bacteria are healthy and functioning, because certain bacteria consume the odorous fat esters that create that rotten smell.
What Constipation Actually Is
Aajonus defined constipation precisely as the inability to defecate, caused by one of two conditions. The first is that the body has digested and absorbed all food consumed and produces no waste. The second is that feces dries in the bowel and peristalsis cannot move it through the sigmoid colon and rectum. The first condition is not true constipation even though it is commonly called that. It occurs in people whose bodies are severely nutrient-starved and absorb everything they consume.
He documented sending thousands of people who believed they were constipated to have ultrasounds done, and none of them, not one, came back with elevated fecal matter in the intestines, except in cases involving cancer. They were not constipated. Their bodies were absorbing everything.
People on the Primal Diet who had previously eaten nutrient-depleted diets their whole lives commonly experienced this. Their bodies were so starved for good nutrients that every particle was absorbed, leaving almost nothing to excrete. Going five to seven days without a bowel movement was, in his view, normal and healthy under those circumstances. The problem began only when the feces that eventually passed was so hard and dry that it damaged the rectum on exit. That hardness results from insufficient fat and insufficient bacteria in the colon, not from the absence of bowel movements themselves.
True constipation, meaning an actual blockage with a hard mass the size of a fist that cannot move, was a different matter. He acknowledged that as a real condition requiring intervention.
Why People Lack Colon Bacteria
The normal colon should contain 3 to 5 pounds of bacteria. Most people are severely deficient. Aajonus attributed this to enemas and colonics, which flush out E. coli and can require 45 to 60 or even 90 days to allow replacement populations to establish. During that period, the person remains at risk of depression and emotional instability because the brain and nervous system are deprived of the finite nutritional molecules E. coli produces. He was unequivocal that enemas and colonics, despite being considered healthful by many alternative practitioners, were damaging to this critical bacterial environment.
Antibiotics were another obvious destroyer. So was alkalizing the intestines with vegetable fiber, green juices, or other alkalizing substances. Aajonus explained that the colon is supposed to be an acidic environment, and that introducing alkaline substances neutralizes the acid bacteria and acid-producing bacteria like E. coli, which then cannot function. When this happens, feces becomes the hard marble-sized pellets that scrape and tear on exit.
He specifically described a professional health practitioner he worked with for over a year, a woman named Marilyn, who ate salad every day because she feared constipation without it. The fiber from the salad was destroying the acid bacteria in her colon. Without those bacteria to sponge and inflate the fecal matter, she had consistent constipation. After a year and three months he told her to stop the salad entirely.
Resolving Hard Feces Without Enemas
Because enemas destroy colon bacteria, Aajonus's preferred method for addressing hard, difficult-to-pass feces was fat implantation. He described a specific physical protocol: get on all fours on the floor, put the face down with the buttocks elevated, roll the stomach like a belly dancer to move food up into the colon and across the transverse colon. Then lie on the side for three to four more minutes and roll the stomach again to distribute fat across the colon.
Cream was his preferred substance for this purpose because it contains fat that E. coli, located at the far end of the colon, normally never receives. The bile already present in fecal matter in the colon partially digests the cream and the bacteria proliferates vigorously in response. He described the colon's color and circulation changing visibly in response to this feeding, and the bacteria releasing held fecal matter as a result.
If someone was detoxing bile or other substances that the bacteria could not feed on, the bacteria would not reproduce and would not sponge out the fecal matter, creating a cycle of constipation. The clay protocol was mentioned as one way to address this situation, providing a substance the bacteria could grow on without being poisoned by the detox material.
He also addressed the specific problem of hard feces causing rectal tearing. He mentioned his own history in this regard directly: as recently as 1972, even on a raw diet, the beginning of every bowel movement was so large and hard that it produced rectal bleeding every single time. His rectum was described as thick with scar tissue. After acquiring a tapeworm, all his feces became smaller, thinner, and soft even at the beginning of the movement, and the rectal bleeding stopped. He attributed this to the tapeworm's role in the intestinal environment.
For hard feces from cheese consumption, he recommended always combining cheese with fat, not eating cheese alone in situations where hard feces was already a problem. Cheese eaten with honey is a separate case: it digests fully and stays in the body, reabsorbing poisons rather than passing them out in feces.
Cheese and Fecal Matter
Cheese occupies a specific and unusual role in Aajonus's framework in relation to feces. When consumed without honey, cheese passes through the digestive tract acting as a magnetic sponge. It attracts and absorbs heavy metals and other poisons from the neurological fluid, blood, and lymph as they pass through the digestive tract, holds those poisons, and carries them out in the feces. This is one of its primary therapeutic uses: chelating toxins out of the nervous system and discharging them through the bowel rather than allowing them to recirculate.
He verified this in laboratory analysis of feces, finding that cheese consumed without honey passed through and came out carrying the poisons it had absorbed, essentially unchanged in form from how it went in. He described eating five pounds of cheese in one week after ingesting metal fragments, specifically to pull those metals out through the fecal route.
When cheese is mixed with honey directly in the mouth, the honey enables digestion of the cheese, which means it stays in the body and the poisons it would otherwise carry out are reabsorbed. Therefore, cheese combined with honey cannot serve the chelation and fecal elimination function.
He also explained that firm feces from eating a lot of cheese while on a nutrient-rich diet is not a problem. The cheese is absorbing toxic minerals being thrown into the bowel, hardening around them, and the firmness reflects both that absorption process and the fact that the body is absorbing everything of nutritional value.
Fecal Matter Food And Medicine
Aajonus addressed the consumption of fecal matter from animals as a legitimate practice for specific medical conditions and as a probiotic intervention far superior to any supplement. He was unambiguous on this point and engaged with it at length. He identified three conditions for which he recommended eating animal fecal matter: psychotropic illness, seemingly irreversible cancers, and severe indigestion, non-assimilation, and malabsorption.
His rationale was that fecal matter from herbivores is predigested. A cow digests a maximum of 67 percent of what it eats, meaning 33 percent passes out still containing fats, proteins, and B vitamins in partially digested, immediately bioavailable form. The cow has 60,000 times more digestive enzymes than a human for breaking down cellulose, and food takes 48 hours to pass through a cow's system compared to 24 hours in a human. When a human eats cow feces, that person is receiving material that has already been processed by a superior digestive system for two days, making it far easier for the human to absorb the remaining nutrients.
He estimated that herbivore fecal matter contains approximately 25 percent of the original protein and fat of the food eaten, fully predigested and available. Tribes in poor regions of Asia and elsewhere who cannot afford adequate meat have historically eaten buffalo feces for exactly this reason, acquiring protein and fat they could not otherwise obtain. He documented having seen this personally and considered it a rational survival strategy.
For cancer and psychotropic conditions, Aajonus suggested approximately 2 ounces of animal fecal matter daily until the supply is consumed. He provided specific instructions for sourcing and preparation. The bowel of an animal, not a patty collected from the field, is the correct source, because once fecal matter is exposed to air and oxygen, the bacteria die rapidly and the probiotic value is lost. He specified ordering 1 to 2 pounds of bowel with contents intact, tied at both ends, from an organic farmer. This looks like a fat sausage when received. He recommended placing it in a wide-mouthed quart or half-gallon glass jar without refrigeration, removing the string at one end, scooping out the contents, and resealing. The contents should be consumed as quickly as possible after extraction.
He noted that cow or other herbivore fecal matter tastes like overly cooked vegetables and carries a feces odor. To manage the odor, he recommended a swimmer's nose clip over the nostrils. He described it as something he utilized only remedially, not as a staple, while acknowledging that some individuals have reversed disease with it.
He described the case of an elderly woman who was dying and could not digest anything, experiencing vomiting and diarrhea regardless of what she ate. Her granddaughter's feces was collected and fed to her, and she recovered in 24 hours. He also described his own self-administered test after inadvertently eating approximately 10,000 pinworm eggs and 50 pinworms: he collected his own feces to examine it under a microscope to monitor for parasitic activity.
The University of Toronto research on E. coli byproducts dissolving brain tumors in two to five days was cited repeatedly in this context. The substance identified as "varicoxin" extracted from E. coli was described as a known product of the bacteria that live on and in fecal matter. Yale's use of salmonella to dissolve tumors was cited alongside this, with Aajonus noting that Biome Products had marketed attenuated salmonella for $8,000 per injection. Edward Howel's rat experiments were also cited, showing that rats eating cooked food who naturally ate their own feces had less severe diseases and lived one third longer than rats eating cooked food who did not eat their feces.
People in Georgia, Russia who ate fecal matter as part of their diet due to poverty were documented by National Geographic reporters in the late 1960s as living to 128 to 168 years old. A February 1971 National Geographic article was referenced on this point. Aajonus noted that this article was never republished and that its results were never highlighted in subsequent research discussions. He described the feces-eaters from that region as having fecal matter that was almost entirely digested with no toxins present, and as having better brain and nervous system function than other populations studied.
Why Human Feces Is Problematic
Aajonus drew a sharp distinction between feces from animals eating their natural raw diets and feces from humans or animals eating processed or chemically contaminated food. In the former case, feces is simply undigested food material and is non-toxic. In the latter case, the feces is genuinely toxic and carries real poisons.
He stated that human feces is too toxic for other humans to eat safely because no human in modern civilization is clean and healthy enough to produce feces free of the toxins being continually eliminated through that channel. He would not recommend eating another person's feces unless the source person was living tribally on a natural diet with no chemical contamination.
Because humans are chronically over-toxic and cannot perspire toxins out through the skin efficiently (partly due to living indoors with air conditioning, antiperspirants, and other barriers to skin excretion), the bowel becomes overloaded as a secondary detox organ. Ninety percent of toxins are supposed to exit through the skin, not through the intestinal tract. When skin excretion is blocked, the bowel compensates, and feces becomes loaded with heavy metals, chemical residues, and other toxins that would not be present in a healthy animal's waste.
He specified that feces in a healthy raw-eating animal emits some poisons, but the primary and secondary detox routes are reversed compared to humans: in animals, the skin is primary and the bowel is secondary. In compromised modern humans, the bowel becomes heavily burdened with toxicity.
Non-Toxic Feces From Raw Diets
When wild carnivores like dogs, wolves, and cats eat their natural diets, Aajonus described their feces as containing almost nothing but hair and some hide. All bone is digested. All meat, cartilage, sinew, and tendon is digested. The fecal matter turns white in sunlight and disintegrates into dust within a day. Other animals, birds, coyotes, ravens, and hawks are drawn to eat it because it still contains usable nutrients they can extract.
He described his own experience living in the mountains of Malibu and defecating outdoors rather than in a toilet. He noted that coyotes, ravens, and hawks would consume it quickly. He offered this as evidence that raw-food human feces, while still too toxic to turn white the way a wild carnivore's would, was still substantially more nutritious and less poisonous than feces from people eating cooked and processed food.
For herbivores like cows, horses, and sheep, feces still contains roughly 33 percent of the original food's nutritional content. Even after the animal's multi-day, high-enzyme, 60,000-times-more-capable digestive process, substantial protein and fat remains available in the feces for other organisms to consume. This is why dogs eat feces routinely, why crustaceans like lobsters thrive on fecal matter as their primary diet, and why birds, insects, rodents, and worms all utilize fecal matter as food.
Feces, Nutrient Absorption, and Quantity
Aajonus used the question of fecal volume as a direct readout of digestive efficiency. If someone is producing large quantities of fecal matter, the body is not absorbing as much as it could. If someone produces very little, absorption is excellent. He noted that when people transition to the Primal Diet from years of processed food consumption, their bodies are so starved for real nutrients that they absorb everything and produce almost no feces, which alarms them because they have been conditioned to expect daily bowel movements.
When food intake increases or the body is not under nutritional stress, more fecal matter will naturally result because not all food needs to be fully extracted. He described this as "feeding nature a little bit better" and considered it entirely appropriate.
He also specifically addressed the case of babies. When a baby on raw milk and raw dairy does not pass fecal matter easily and produces hard, rock-solid small stools, it is not constipation from the diet. It is a colon that is severely deficient in bacteria, so the bacteria that are present are refusing to release any material, holding it until they extract every possible nutrient. The solution is building bacterial populations, not switching foods.
Diarrhea as a Process
Aajonus addressed diarrhea in the same framework. He described it not as a dangerous condition but as the body adjusting its bacterial levels and composition. He stated flatly: do not fear diarrhea. It is a natural process of cleansing and digestion adjustment. The body uses diarrhea, alongside vomiting, as a pathway to rapidly move toxicity through and out when it needs to. Neither diarrhea nor constipation as he defined them were conditions to be feared or aggressively treated in the absence of an actual structural blockage.
Feces, Soil, and Ecological Role
In the natural world, Aajonus emphasized that feces is fertilizer and has been used as such for as long as life has existed on earth. It supports worms and soil bacteria. It grows the soil layer and feeds the earth. He noted that because of the toxicity in modern human feces from industrial chemicals, farming chemicals, and processed food residues, contemporary human excrement creates irregularities in soil and in the plants that absorb it, disrupting the natural cycle that non-toxic feces would otherwise support.
In his view, the planet grows slightly each year in part because of organic waste returning to soil. Organic fecal matter is a fundamental mechanism of ecological cycling, not something to be treated as dangerous refuse to be sequestered from the natural world.
