Kidneys
Paired organs whose single designed function is fluid regulation for temperature control, not toxin filtration. By removing or retaining water in the bloodstream, they allow the body to tolerate temperature swings of fifty to sixty degrees Fahrenheit.
The kidneys are a pair of organs positioned at the back of the abdominal cavity, kidney-shaped like kidney beans, whose primary and in a healthy body essentially sole function is the regulation of body temperature through the controlled removal of water from the bloodstream. Aajonus described them as fundamentally simple organs that have been made unnecessarily complex in the popular understanding by a medical profession that frames them as generalized toxin filters. In his framework, the kidneys are not designed to filter toxins at all. Their design is to manage fluid levels in the blood so that the body can warm or cool itself in response to changes in atmospheric or body temperature.
The kidneys work in close coordination with the spleen. When the body gets cold, the kidneys discharge excess water from the bloodstream to thicken the blood, which allows it to retain heat, while simultaneously the spleen dumps its stored reserve of red blood cells back into circulation to thicken the blood further and sustain warmth. When the body becomes too hot, the kidney stops discharging fluid, retaining water in the bloodstream to thin it and allow the blood to function as a coolant, similar to a radiator. Aajonus noted that without functional kidneys, the body could only tolerate roughly a seven-degree temperature change before dying, but with healthy kidney function, a person can adjust to a fifty to sixty degree Fahrenheit change, or roughly twenty-five degrees centigrade.
In Aajonus's reading of physiology, the kidney has one chemical manufacturing job: it produces ammonia. This ammonia is not the toxic, concentrated ammonia of commercial cleaning products, but an organic ammonia produced by the organ itself. The ammonia acts as a kind of negative magnetic repellent that prevents red and white blood cells from entering the kidney tissue along with the fluid that passes out of the blood. Because red blood cells are deeply integrated with everything else in the bloodstream, tightly bound to all nutrients and serum components, the kidney needs this ammonia to accomplish the separation. Without it, every urination event would result in the loss of substantial quantities of red and white blood cells, producing chronic anemia. Aajonus pointed out that the body produces only about two ounces of red blood cells per day in the bone marrow, making constant loss through urination a physiological impossibility to sustain.
Ammonia Production and Its Role
Ammonia is manufactured by the kidneys in the same way the stomach manufactures hydrochloric acid: it is a specific secretion designed for a specific mechanical purpose. When blood passes through the kidney, the ammonia creates a barrier that repels red and white blood cells. The red blood cells in particular are very strongly bound to the rest of the blood's components, which is why the horse, whose blood is especially resistant to giving up its red blood cells, produces nearly three times more ammonia than any other animal in order to accomplish the separation. Cows produce significant ammonia as well, but somewhat less than horses.
The result is that urine is essentially blood serum without most of its red blood cells, with a small amount of added ammonia. Aajonus was emphatic that urine is not a waste product in the conventional toxic sense. It contains all the vitamins, proteins, enzymes, fats, minerals, and other nutrients that are circulating in the blood at any given time. In healthy individuals eating a good raw food diet, the urine would be rich in exactly those nutrients because the blood is rich in them. The ammonia present in urine also has a mild chelating effect, meaning it can bind with certain toxins and help carry them out.
Aajonus noted that the kidneys do let some red and white blood cells pass through, particularly damaged or weakened cells that are being discarded from the system. The main job is to stop the loss of red blood cells, and secondarily to retain about fifty to seventy percent of white blood cells. If urine appears pinkish or orange-brownish and the person is not drinking beet juice, Aajonus identified that as a sign of excessive red blood cell loss in the urine, indicating the kidneys are not filtering effectively and the person may be trending toward anemia.
Temperature Regulation and Spleen Partnership
The kidneys were not always required to be heavily involved in temperature regulation. Aajonus explained that in a clean, non-toxic body eating all raw foods without exposure to industrial toxins and without the habit of drinking excessive water, the spleen alone could handle temperature regulation by adding or removing red blood cells from circulation. The kidneys became more heavily recruited into that function because of the contamination of the modern body and the practice of drinking large amounts of water, which creates a constant excess of fluid that must be managed.
When a person gets cold, the urge to urinate increases because the kidney is actively removing H2O from the blood to thicken it. When a person gets hot, urination becomes infrequent or impossible because the body is retaining fluid to keep the blood thin and the system cool. Sweating, not urination, is the body's mechanism for releasing heat when it is too warm. Aajonus pointed out that dogs fed natural whole raw foods urinate only in small amounts and infrequently, because raw foods are already fifty-five to ninety percent water by composition and the body does not need to discard large quantities of fluid constantly. Dogs fed dried kibble drink enormous amounts of water and urinate frequently because there is no fluid in their food.
What Urine Actually Is
Aajonus described urine as nothing other than blood without a large proportion of red blood cells, with a small quantity of ammonia added. Everything else that is in the blood, all the proteins, all the fats, all the vitamins, all the minerals, all the enzymes, all the bacteria, and any toxins present, passes into the urine unchanged. This is why, in his view, drinking urine has historically been a meaningful therapeutic and nutritional practice. Many civilizations and tribes have used urine as an antiseptic and a nutrient source. In India, where widespread vegetarianism results in protein deficiency, drinking urine to recycle proteins is a longstanding practice. Astronauts in space programs drink filtered urine. Aajonus noted that if the blood is clean and the diet is good and raw, the urine will reflect that quality.
He drew a distinction about who should and should not drink urine. For vegetarians who lack sufficient protein, he recommended urine drinking as a way to recycle proteins. For people on a good raw diet with plenty of raw meat and dairy, he said urine is a little too acidic and he did not recommend it as a regular practice. He also noted that if someone's diet is heavily based on vegetarianism and they lack protein, drinking urine gives the body a second pass at those nutrients.
The Bladder
The bladder exists for the simple reason that without it, a person would be constantly dribbling urine throughout the day as the kidney steadily separates fluid from the bloodstream. The bladder is a storage container that accumulates urine until a sufficient volume is present to warrant a deliberate trip to urinate. The capacity and health of the bladder determines how much fluid it holds before signaling the need to void. Aajonus presented this as straightforward mechanical design with no mystery or complexity.
Kidney Stones
Kidney stones, in Aajonus's framework, are crystallized cooked vegetable-fat resins, crystallized hydrogenated fats and oils, and cauterized mineral salts that accumulate and form clusters in the kidneys. He stated that he had many kidney stones analyzed and found them to be composed largely of food additives and processed mineral compounds. The hardest stones are dense with heavy metals. All people who develop stones develop them from cauterized minerals and resins that their bodies cannot eliminate through the skin via perspiration, so the body discharges them into the kidneys where they may collect, or into the bladder, with collection in both places being rare. Some people's bodies instead dump these materials into the liver or gallbladder.
Aajonus made a categorical distinction: raw fooders who do not take supplements do not get kidney stones. People who eat cooked food, processed food, or take mineral supplements are the ones who develop them. He stated that no tribe he was aware of had ever heard of a kidney stone, bladder stone, liver stone, or gallbladder stone. He attributed the entire phenomenon to the toxic conditions of modern industrialized society.
The mechanism he described is that cooked foods, especially those subjected to high heat, produce lipid peroxides and heavy acetic amines, which are the specific compounds that damage and irritate the kidneys. These compounds are only formed through cooking and are not present in raw foods. Raw meat does not produce these damaging byproducts.
What Damages the Kidneys
Aajonus identified cooked food as the primary source of kidney damage, specifically through the lipid peroxides and heavy acetic amines produced during cooking. Supplements contribute by introducing cauterized and concentrated minerals that the kidneys cannot process and which crystallize into stones. Industrial chemicals and heavy metals are also implicated; if fat levels in the blood and intestinal tract are low, toxic chemicals that would otherwise be bound to fat and neutralized may instead be discharged through the kidneys, causing damage. He described the kidney as a sensitive organ not designed to handle large quantities of toxins and stated clearly that sending toxins out through the kidneys is not ideal because the kidney has one job and is not built for detoxification.
When blood and intestinal fat levels are inadequate, chemicals can be directed toward the kidneys. If the kidneys are heavily damaged, bacteria will then feed on the damaged kidney tissue. Aajonus was clear that in this sequence it is the chemicals that destroyed the kidney tissue, and the bacteria are performing the cleanup function of consuming and eliminating the damaged material, not causing the destruction themselves.
He also identified drinking excessive water as harmful to kidney function. When too much plain water is consumed, it dilutes acids and beneficial bacteria in the stomach and intestines, floods the bloodstream and neurological fluid and lymphatic system, and forces the kidneys to work extremely hard to discharge all of that excess fluid. The urine becomes progressively lighter and lighter as the kidneys fight to expel the water without losing red blood cells, and the person loses massive quantities of blood nutrients through this process. Aajonus was emphatic that drinking large amounts of plain water is not beneficial and that the fluid needs of the body should be met through raw foods, which are naturally fifty-five to ninety percent water by composition.
Ammonium sulfate, listed as a vaccine filler described as an inorganic chemical compound used as a fertilizer and protein purifier, is known to cause kidney and liver damage and gastrointestinal dysfunction. Aajonus listed this among the ingredients introduced into the body through vaccination.
Kidney Support And Stability
The easiest way to stabilize the kidneys, in Aajonus's view, is to eat meat, particularly red meat and chicken. These provide the raw proteins needed for cellular regeneration and stabilization. The reason protein has a reputation for being hard on the kidneys is that cooked protein is the problem. Raw protein does not produce the damaging byproducts that cooked protein does.
For kidney infections, he described a specific protocol: drinking a large glass of good mineral water with three tablespoons of fresh raw lime juice and either beet juice or half a cup of raw fresh vegetable juice containing one ounce of beet juice, with three ounces of good mineral water, consumed half an hour before eating, for the duration of the infection. The raw lime and beet juices, along with fresh raw corn on the cob, help regulate bacterial levels so that infection does not become excessive. If there is blood in the urine, he recommended staying off the feet and remaining sedentary.
Simply following the raw food diet typically addresses kidney problems without the need for special protocols. He told one person with significant kidney tissue death, roughly one third of the left kidney and fifty percent of the right, that doing the diet alone would take care of the issue, and that there was nothing special required for the kidneys beyond that.
The tallow fat that surrounds the kidneys, the suet, was discussed in the context of an observation Aajonus made: he found that when given to people with kidney disease, the suet sometimes went first to the heart and thyroid rather than directly to the kidneys, because the body prioritized those organs. He noted that the body determines where fats are directed and that experimentation is required because individual bodies use different fats in different ways.
Kidney Fat and Toxicity Buffering
Aajonus observed that people who carry significant toxic burden often have a thick layer of tallow around their kidneys, sometimes an inch and a half to two inches thick. This fat accumulates because the kidneys are processing a large volume of toxins from the bloodstream, and the body builds a fatty buffer to protect the organ. In the context of fat weight loss programs that are not producing results, he pointed to this protective fat around the kidneys as a potential reason: the body refuses to burn that fat because it is actively needed as protection.
Having Only One Kidney
Aajonus addressed the situation of a person with only one kidney directly. He explained that normally the two kidneys alternate, with one filtering while the other rests and rebalances itself. When only one kidney exists or functions, ammonia production is impaired because that alternating rest cycle is eliminated and the single kidney must filter continuously. He described this as a tremendous loss, particularly for people who want to be physically active. Challenging sports become difficult, and both lifespan and life quality are compromised when only one kidney is present.
When Kidneys Fail
In the case of a fifty-nine year old man with two failed kidneys crystallized with kidney stones who had been on dialysis three times per week for more than two years, Aajonus was consulted. The man also had Crohn's disease with sections of intestine removed and hepatitis B. Aajonus had stated in his book that if an organ has failed it cannot be revived, and this case was presented in the context of that principle. His general position was that failed organs cannot be brought back to function, though the remainder of the body can be supported.
He noted in another context that when kidneys are not purifying the blood properly, bile begins to be released into the system to break down the toxic substances that the kidneys are failing to process, which leads to jaundice. The bile accumulates throughout the system and causes progressive bloating. He distinguished this from the yellowing caused by bile stored throughout the body when the kidneys are functional but bile pathways are blocked, saying that in true kidney damage, the bile goes into the system to compensate.
Pre-Surgery Preparation
Why Kidneys Exclude Toxins
Aajonus was specific that the kidneys are not a desirable route for toxic elimination. He described the kidney as too sensitive to handle toxin loads. The preferred routes for toxin elimination are the bowels, through vomiting, and through the skin via perspiration. Urination is listed last and described as not a good way to send toxins out of the body precisely because the kidney's single designed function is fluid regulation, not detoxification. When toxins are forced through the kidneys, the organ is damaged. He recommended identifying substances that can absorb ingested poisons, hold them without releasing them, and then move them out through the bowels, through emesis, or through the skin rather than through the urinary tract.
