Raw animal brain and the raw tissues of calves, pigs, and other animals occupy a foundational position in Aajonus Vonderplanitz's primal diet framework. These foods are understood not as exotic or peripheral ingredients but as some of the most concentrated, biologically appropriate protein and fat sources available to the human body. The pig is given particular significance because, as Aajonus stated repeatedly across many seminars and transcripts, "the pig has a digestive tract almost identical to ours", more similar to the human digestive tract than even the great apes and other primates. This biological similarity makes observations about pig health and pig diet directly applicable to understanding human nutrition.

Calf tissues, including calf brain and calf liver, appear specifically in Aajonus's documented laboratory experiments with parasite-infested raw meats fed to aging and infirm animals. Raw animal brain in general, specifically the brains and nervous system tissues of various animals, is discussed in the context of neurological reconstruction, with the important caveat that eating the brain and spinal cord of a diseased animal (such as one affected by mad cow disease) carries specific risks not applicable to muscle meat from the same animal.

The overarching framework is that raw meat of any kind, red or white, four-legged or two-legged or no-legged, provides the irreplaceable protein substrate for cellular division and regeneration. "Raw meat is the only protein that facilitates nerve-tissue regeneration and cellular reproduction," Aajonus stated. Among the different categories of raw meat, each plays a specialized role: red meat rebuilds blood, muscle, and glands; white meat (fowl, pork, shellfish) rebuilds connective tissue, nerves, lymph, and skin; and fish reconstitutes the inner workings of the brain and nervous system.

Aajonus made specific and detailed statements about how the brain functions and what it requires for regeneration:

"The brain doesn't contain nerves, that's why you do brain surgery on somebody totally weak because there's no pain there. There's no nerves in the brain, it's neurons. So the neurons can reproduce. Ganglia, synapse, all that can be reproduced as long as you're eating raw meat is what I can do. If you don't eat raw meat, for some reason there's so much toxicity and the chemistry is so different that nerve cells and neurons cannot divide."

This is a crucial statement: neuronal division and reproduction, the fundamental mechanism by which the brain and nervous system repair themselves, is described as contingent upon raw meat consumption. Without raw meat, the chemical environment is so disrupted by toxicity that neurons cannot divide. With raw meat, the neurons, ganglia, and synaptic connections can all regenerate.

He elaborated on how different types of raw meat serve different neurological functions:

• Fish: "Fish will help replenish neurological fluids, but it doesn't help rebuild the myelin." Fish is "mainly to reconstitute the inner workings of the brain and nervous system." In his laboratory tests with animals: "they all produced, they did nicely with brain activity and neurological activity with fish, no matter what kind it was."

• White meat (fowl, pig, shellfish): "The actual myelin sheaths and the epidermic walls of cells, intestines, skin everywhere is better reproduced with white meat." Specifically: "Mainly white meat of fowl, pig, shellfish, oysters. Those were helpful along with the poultry. But without the poultry, it did not rebuild the nervous system as well."

• Correction of earlier claim: "That was a mistake that I made in the first book. I spoke a little too soon until my experiments were over because it looked like it was, but it wasn't. So neurological progression and development did not happen by eating fish alone."

He also described what white meat does for skin versus nervous tissue: "White fish with red meat, fish is mainly to reconstitute the inner workings of the brain and nervous system. But the actual myelin sheaths and the epidermic walls of cells, intestines, skin everywhere is better reproduced with white meat."

Regarding the broader role of white meat in neurological healing: "White meat, I mean like if you have a wild rabbit, any fowl, fish, even though it's white meat, it reconstitutes the inner workings of the nerve tissue, but does not help to rebuild the myelin, as I had once believed. It helps the inner workings of the nervous system, but does not help the actual tissue development. It takes white meat to do that quickly."

Aajonus returned to the pig-human digestive parallel throughout his seminars because it serves as the foundational evidence for why humans are meant to eat meat:

"Our closest cousin digestively is the pig. The pig has a digestive tract almost identical to ours. Some of the other bacteria and other things are not, but the trichinosis is, and even the stomach is very, very similar."

"We have a digestive tract more like the pig than we do the apes and monkeys. Other primates."

"The pig, which is an omnivore, if the pig has a choice... I never saw them eat anything other than moles. They loved moles and they loved insects, and they mostly ate animal products. If they came across a dead animal or a limping animal, even a coyote, they would have them eaten and devoured in hours."

"The pig, if we look at that and us, they're so similar that if we watch the pig, they're meat eaters. We look at the creatures, the other humans on the earth that have no disease, they're raw meat eaters. So that pretty much says, makes a good statement about what we should be doing."

The parallel between pigs and humans extends to behavioral responses to dietary imbalance:

"If you've ever raised pigs, you know that pigs are very temperamental. You give them a lot of high-sugar stuff and a lot of sweet stuff, a lot of skim milk. They are crazy. They will tear up their yard. If you don't have a ring on their nose, they'll be digging for every insect and every mole that they can because they all start getting protein deficient, just like the human does."

"So the pig, to be very, very balanced, and the human, they need a very structured diet."

"That's how animal cells reproduce is they divide, they grow up, divide again, and grow up and keep going that way. And there's all kinds of things..."

The implication is that raw meat provides the necessary chemical environment for this cellular division to proceed correctly, cooked meat, with its denatured proteins and altered chemistry, cannot serve this function.

Aajonus was emphatic about clarifying what he meant by "white meat" because the color of the flesh is irrelevant to the classification:

"Red are large four-legged animals and white are two legs or no legs, like from the ocean. Crabs fall into the white meat, they have legs, but, six legs. So it has to be large four-legged animals and even rabbits and gophers and all those animals. Even the pork is, although..."

"When I talk about red and white, they are not colors, they are classes."

"Just like fish, you can have tuna that's red, it's still white meat. The way it reacts."

Critically regarding pork: "Mainly white meat of fowl, pig, shellfish, oysters. Those were helpful along with the poultry." Pork is classified as white meat even though it is a four-legged animal, this appears to be because it falls into the classification based on its functional properties in the body, similar to fowl and shellfish, in terms of rebuilding connective tissue, nerves, lymph, and skin.

The entire framework depends on the meat being raw. This is not a matter of preference but of biochemistry:

"Raw meat is the only protein that facilitates nerve-tissue regeneration and cellular reproduction."

"If you don't eat raw meat, for some reason there's so much toxicity and the chemistry is so different that nerve cells and neurons cannot divide."

Regarding his experience with the mad cow situation in Paris: "I think when you eat it raw, your body is prepared to handle and discard the toxicity."

Aajonus conducted laboratory experiments comparing frozen and non-frozen raw meat, with the following findings:

"We put them into two groups and fed one of them the same meat that was frozen, the other non-frozen... the group that ate the raw meat non-frozen healed very rapidly of almost all of their diseases... the group that ate it frozen healed in 5 times, took them 5 times longer to heal, then but they did heal, but they also had another problem... they got rid of maybe some other problems like arthritis or rheumatism or their multiple sclerosis but they developed a skin disorder one of them even developed mange from it."

"The animals that ate it raw got well with no skin side effects."

This means non-frozen raw meat is definitively superior to frozen raw meat. Frozen raw meat is better than cooked, but it heals five times more slowly and introduces skin problems that do not occur with fresh non-frozen raw meat.

Wild animals are consistently recommended over domesticated ones where possible:

"Any wild animal is going to be healthier than a domesticated animal."

"If you catch a wild boar, go for it. I would eat it in a second."

Regarding the specific problem with domesticated pigs: "Pigs have been living on cooked foods for so long they're anemic and they're very diseased and they're unhealthy animals. Even the ones, except for the wild pigs. But domesticated pigs have been sick animals for a very, very long time. And that's why I don't recommend them."

However, this concern was qualified or contradicted in other passages where Aajonus expressed comfort eating organic pastured pork: "I ate pastured pork this morning, enjoyably. The bad info about health-giving pork is myth. As long as an animal eats what is natural in its natural state, the animal, as long as it is not a poisonous toad, is good to eat."

He also described visiting an Amish farmer's pigs approvingly: "I got all the milk, unrefrigerated, gallons of it, got the cheese and got everything else, saw his pigs, saw the chickens running around eating these maggots and this rotten meat all full of feathers and friendly to each other... The pigs were happy. They were eating all of the discarded milk, the stuff that got a little too fermented to turn it into good kefir or yogurt. They got all that discarded stuff. Man, they loved it."

One of the most specific references to calf brain in Aajonus's teachings involves an experiment with parasite-infested tissues:

"We took 14 animals all from the age of 12 to the age of 16 and these were so called at risk types of creatures because they were an old age and all of them weak and feeble and fed them various different types of parasite infested meats. Calf's brain was infested with flukes and worms and liver worms and calves liver. We fed that to all these animals not one of them got a parasite. Not one of them got a parasite and they all did very well and got healthier."

"The animals that we put in an ad for and got that already were infested with parasites we took them and fed them raw foods and they all got better and their parasites continued until their death and we performed autopsies on them and their innards were brilliant like they were young. So wherever they had whether they..."

This is a pivotal passage. The experiment demonstrated that: 1. Eating raw calf brain infested with flukes, worms, and liver worms did not transmit parasites to the animals consuming it. 2. All animals that ate the parasite-infested raw calf brain and calf liver got healthier despite the infestation. 3. Animals that already had parasites and were fed raw foods got better, with their parasites continuing until death, but upon autopsy, their internal organs were "brilliant like they were young."

Aajonus was specific about the contamination risks from vaccines and hormones in animal products:

"Don't eat the spinal cord, you know, unless you know it's an organic animal and there's been no vaccine."

"A lot of the toxins that we put into animals, they shoot them in the rump. So those particular cuts you have to be careful of. Some will shoot it into the upper shoulder. Most of them do it in the neck."

"North Star Bison vaccinates their breeding female. So you need to tell Mary Gracie that you're my patient. You don't want any vaccinated meats or glands or organs from any vaccinated animal."

Regarding hormones: "If it's plastered with hormones, you're taking some risks."

Regarding pork specifically: "As long as it's organic, it'd be fine."

"If you catch a wild boar, go for it. I would eat it in a second. Deer's wonderful. Fabulous. Any wild animal is going to be healthier than a domesticated animal. I would definitely do it. Because it might have picked up pesticides or pesticides from..."

The Amish farmer model is presented as an example of properly raised pigs: organic, pasture-based, eating fermented dairy discards and living naturally. This is the sourcing standard for domesticated pork.

When asked about raw organic liverwurst (braunschweiger), Aajonus acknowledged: "It is illegal for any prepared meats to be ra...", indicating that commercially prepared raw meat products face legal restrictions, and therefore sourcing raw animal products requires going directly to farmers.

Regarding mad cow meat specifically: "I also always ate butter with that meat meal. So if there was any toxicity in it, I was going to have enough to take care of it."

This establishes the principle that raw fat, specifically butter, is the required pairing with raw meat to neutralize toxicity and protect the body during digestion and detoxification. This is not optional but constitutes a biochemical protection mechanism.

In the laboratory experiment with frozen vs. non-frozen meat: "the group that ate the raw meat non-frozen healed very rapidly of almost all of their diseases they didn't get any butter or anything else it was just meat and with meat fat", indicating that meat fat itself provides the fat buffer even when separate butter is not added, since the meat fat accompanies the protein.

While not strictly "brain" preparation, Aajonus consistently documented the combination of raw blood and raw milk as one of the most powerfully nourishing pairings he had encountered:

"It gives you so much energy so fast. It is phenomenal. It's like taking a superpower drug. I mean, it keeps you clear. It's not like, you know, other drugs. They make the body wild, and the mind doesn't go with it, you know, but this takes the whole body and mind and nervous system with it. It's phenomenal."

The milk serves as the fat buffer and delivery vehicle for the blood, with the combination tasting "just like ice cream" or "milkshake" rather than metallic blood.

---

"No need to be concerned unless, maybe, you eat the brain and spinal cord of an affected animal.", This implies that small or incidental consumption of diseased nervous tissue carries risk, while muscle meat from the same animal does not.

Aajonus ate mad cow muscle meat "three months out of the year for three and a half years" with no ill effects, but explicitly did not eat the brain or spinal cord during this period.

In the experiment: 14 animals ranging from 12 to 16 years old (described as "at risk") were fed raw calf brain infested with flukes, worms, and liver worms. "Not one of them got a parasite. Not one of them got a parasite and they all did very well and got healthier." This establishes that eating parasite-infested raw calf brain, in Aajonus's experimental observation, does not result in parasite transmission to the consumer.

Aajonus described this preparation in extensive detail across numerous passages as one of the most nourishing and delicious foods he had encountered. While it features blood rather than brain specifically, it demonstrates the use of raw animal tissues in primal preparations:

Method 1, Bladder pouch: Fill half of a dried animal bladder (urinary bladder or gallbladder) with raw milk (cow, goat, or water buffalo), then fill the other half with fresh raw blood (from a living bull bled via bamboo shoot into the jugular vein). Shake and drink immediately. Tastes "just like milkshake" or "just like ice cream."

Method 2, Gallon jars (Pangaea ceremony): Slaughter a goat humanely (spin in harness until unconscious, then cut jugular). Bleed into gallon jars half-filled with the same animal's raw milk. Stir. Pass around and drink communally.

"We had two gallons of it, and it was gone within about 20 minutes, all of it."

"It gives you so much energy so fast. It is phenomenal. It's like taking a superpower drug."

Referenced in the context of the butchering of a calf that died in difficult labor: "I take out the bone marrow raw and they're all fascinated by this. But it was delicious. Fresh, warm out of the bone marrow."

"Raw snake tastes like fish." This is presented as another form of white meat/fish-category protein that works similarly to fish for neurological reconstitution.

The most extensively developed "derivative" concept from the pig-brain-calf-animal complex is the trichinosis parallel, because it is used by Aajonus to explain the entire dietary framework:

Dr. Joel Weinstock (gastroenterologist at the University of Iowa/University of Utah, both locations mentioned across different transcripts):

1. Grew up on a farm, saw healthy pigs wallowing in mud and slop 2. Became a professor and observed university pigs in sterile conditions were sick 3. Tested intestinal tracts: the only difference was no trichinosis in university pigs 4. Infected university pigs with trichinosis → they got well in five days / one week 5. Repeated the experiment many times with consistent results 6. Obtained FDA license to administer trichinosis to six human patients with chronic intestinal disease 7. Those six patients all improved

Aajonus extrapolated: "We are most like, all animals in the world. Even more so than primates, the pig. We have a digestive tract more like the pig than we do the apes and monkeys." Therefore, the human digestive requirement for trichinosis mirrors the pig's. Raw meat consumption naturally maintains this beneficial parasitic relationship. The sterilization of food and administration of antibiotics destroys it, leading to disease.

---

Aajonus presented a specific historical argument for why pigs were banned in religious dietary laws:

"Back in that time, they were using pigs as garbage trucks. They would throw the cooked food out the windows. The pigs went in the streets and they ate all the cooked food. They were the first animals to get severe diseases, besides humans. So it was illegal to eat them because they were very diseased animals, and they were the garbage collectors. If you ate the garbage collectors, you had no garbage left. And then the putrefaction stayed in the streets. So there are many reasons that the pig was outlawed in those times."

"They're too much like humans, eating-wise, in the Bible."

The prohibition was therefore a pragmatic civic sanitation measure, not a statement about pork being intrinsically unhealthful. The pigs themselves were diseased because they were eating cooked food garbage, not because pig meat is inherently problematic.

"In Egypt and, um, in Jerusalem, you know, all of that area. And all over the world, pigs ran, roamed the streets to eat garbage that people, they'd cook the food and dump it out the window and the pigs would come around and eat it. Well, pigs have been living on cooked foods for so long they're anemic and they're very diseased and they're unhealthy animals."

"No need to be concerned unless, maybe, you eat the brain and spinal cord of an affected animal. I ate mad cow meat in Paris, for 3 months a year for 3 1/2 years over 10 years ago, and did not suffer any ill reactions."

"My last trip home from Paris, I read in this magazine on the plane that Carrefour Supermarkets had been selling the mad cow meat for all that time."

"I was eating mad cow for three years, three months out of the year. And I didn't know."

The implication is that the mass media panic about mad cow disease was disproportionate to actual risk, particularly for those eating raw muscle meat, but the brain and spinal cord of an affected animal do carry genuine risk because that is where the pathological material concentrates.

"Pigs ran the streets and they ate cooked food and they were the first animals to get severe diseases, besides humans." This is presented as the definitive historical demonstration that cooked food causes disease, visible in the pig as a mirror of human health outcomes, because the human and pig digestive systems are so closely matched.

The Amish farmer's pigs, by contrast, eating fermented dairy discards and living naturally, were "happy" and healthy, demonstrating that properly fed pigs on a raw/natural diet are healthy animals and appropriate food sources.
