In trying to figure out a case of chronic hives that I've been struggling with, I've been coming back again and again to the idea that I have some type of dysfunction in my nervous system. The other day I came across an interesting book, Nutrition and the Autonomic Nervous System by Nicholas Gonzalez. He put together a protocol for treating various forms of cancer using diets tailored to the type of nervous system of the patient. He bases his framework largely around Francis Pottenger Sr.'s work during the 1930's, who theorized that diseased states were caused by autonomic imbalances. The autonomic nervous system is composed of the sympathetic (fight or flight) and parasympathetic (rest and relaxation) systems. Pottenger discovered through his studies that some people were dominant in one system or the other. People who are sympathetic dominant have strong muscles, bones, hearts, endocrine systems, and the left hemisphere of the brain were strongly developed. These are the structures of the sympathetic nervous system. Meanwhile their right brain hemisphere, digestive system, pancreas and liver are inefficient and weak (these are the structures of the parasympathetic system).
Nutrition and the Autonomic Nervous System
Nutrition and the Autonomic Nervous System
Pottenger considered autonomic dysregulation as the root of many diseases and disorders and that three minerals - calcium, magnesium, and potassium where primary regulators of these systems. From the introduction, "He (Pottenger) found that the administration of magnesium would suppress the sympathetic system, potassium stimulated the parasympathetic system, and calcium stimulated the sympathetic system." His book Symptoms of Visceral Disease explores his research from a medical perspective.
Gonzalez next introduces to William Kelly, an orthodontist who in the 1960's became very ill and was diagnosed with Pancreatic cancer that was far advanced and spread to the liver, lungs and bones. His liver was so inflamed that he could feel it protrude through his abdomen. His doctors thought he only had weeks left to live. He had an interest in nutrition and thought he might try some experimentation with diet. Certain foods, specifically red meat and poultry made him feel immediately ill. He could feel the inflammation of his liver right away. Other foods like raw fruits, leafy greens and fresh vegetable juices made him feel stronger. His mother came to help him and under her advice Kelly focused on eating a largely vegetarian diet that included the utilization of enzymes along with coffee enemas for detoxing. Through this course of treatment he got better and better and eventually was cured. I think it was this protocol and treatment that served as a springboard for the vegetarian diet advocates in the US. However, these advocates stop there and ignore the rest of his work. Don't get hung up on the vegetarian issue for now. His work looked at how different nutrients stimulate the nervous system in specific ways and how the same nutrient can be either very helpful or very harm for specific types of people, and more importantly this work shows how different foods feed the two different parts of the nervous system. This relates to the phenomenon of contraindications. I'll return to diet as it relates to the nervous system in a bit, but first a little detour.
The nature of contraindication itself seems rooted in the levels of dominance an individual has in either the sympathetic or parasympathetic system. For example, I can eat walnuts and be completely fine, but if I go near poison ivy (I don't even have to touch it) I can end up with an extreme rash that covers my entire body. Conversely, a different type will go into anaphylactic shock if they eat the smallest bit of a walnut, and yet they could roll around in poison ivy without getting any rash at all. Our allergies (not including food sensitivities), lack of allergies, and reactions to various substances may actually provide a lot of insight into our individual nature.
Last week I came across the video below. In it Andrew Weber talks about how he has a deathly allergy to wasp stings and walnuts. If he gets stung by a wasp or accidentally eats a walnut, he'll go into anaphylactic shock and needs a shot of epinephrine to save his life. He came across some info that suggested urine therapy could counter the shock. His theory was that homeopathic antigens are excreted in the urine within seconds of getting stung, and that by urinating and putting it under your tongue, that this contains the information your body needs to identify the antigens to counter the shock. He said some years later he was indeed stung, he tried this method, and didn't have a reaction. Here's the video:
At this point I had made a bit of progress with my hives, but they were still coming on each day and I really wanted an answer. So I took the plunge and tried this therapy to see if I'd see some improvement (don't judge me!). Some hours later I had one of my worst reactions yet. I was going on a fast and didn't want to take any medication, so I took a cold bath instead which has always helped in the past. I also saw some bentonite clay and thought that would be helpful to sooth the reaction, so I piled that stuff on too. Interestingly, the cold bath wasn't having any effect. I didn't even feel cold during that bath and actually my body heated up very quickly after getting out. And then my hives got a lot worse than they already had been. My entire right arm was one giant angry hive.
The thing to note here is that urine acted in place of epinephrine for Andrew Weber's deathly allergy. It probably wasn't a homeopathic solution that did the trick but rather that urine is a major stimulant for the sympathetic nervous system. I actually just looked it up and found that epinephrine is indeed excreted through the urine. This can be life saving info for people who have weak sympathetic systems and have dangerous allergies, but for me it sent my system further into a tizzy. Calcium is also a primary operator for the sympathetic system, and it is the main component of bentonite clay. The bad news for me was that the combo sent my hives into the extreme, but the good news was I had just read the following section on calcium in Gonzalez' book so it served as a strong signal to continue looking down that road.
Nutrition and the Autonomic Nervous System
When talking to my allergist, one of the first things he told me that my condition wasn't an allergy. I understood this to be true because their onset doesn't come as a result of eating a specific food or being exposed to anything in particular. I had long ruled out that it was an allergy, but what stood out for me when I read the above section was that my particular type of hives are actually the opposite of an allergy, a bizarro-allergy.
In any case, I'd like to revisit Kelly's work on cancer. After he had success with his own cancer, he started seeing others with different types of cancers as well various health conditions. But he found that the vegetarian diet he was doing for himself was actually destructive for other illnesses. Through trial and error he tried different diet combinations that included raw vegetarian, cooked vegetarian, raw meat, raw meat with veggies, and cooked meat with veggies for various patients. What lead to improvement in one condition could lead to deterioration in another.
Nutrition and the Autonomic Nervous System
Kelly saw varying levels of sympathetic and parasympathetic efficacy in his patients based on their nutritional needs and he came up with 10 types:
He found targeted diets for each of these types. As a rough summary, the extreme sympathetic dominant types did best on a mostly vegetarian diet with just a little bit of animal protein. The extreme parasympathetic dominant types did best with lightly cooked red meat and as much fat as possible. And then there were variations for those who fell between the extremes. I think the chart is super interesting, but there may be some variations not listed and there may be another dimension to our system to consider.
Gonzalez' research into autonomic types also included a look at Pavlov's dogs along with the work of Dr. Funkenstein (a Harvard doctor who continued with Pavlov's work, but interestingly there is nothing online about him). Pavlov had two overarching classifications of his dogs' reactions to stress - excitatory and inhibitory. The excitatory dogs became aggressive when exposed to a shock, and stayed in the aggressive mode long after exposure. The inhibitory dogs basically shutdown and retreated when exposed to a shock and also stayed in that mode long after exposure. He also found two additional types that rebounded fairly quickly from the shock and didn't become stuck in any particular mode. What I think is interesting is that the two extremes match with character disturbance and neurosis in humans.
All this isn't to say that all sympathetic dominant people should just be doing a vegetarian diet. The point is that we are varied individuals and the function or dysfunction of our system may very well call for specific doses of different foods at different times. I think having a dominant sympathetic system with a potentially strong secondary parasympathetic system makes things difficult to sort out, and vise versa. It's like both systems need to be fed, while not letting the other go wonky. There could be periods of needing one type of diet, and then changing to another depending on how things are balancing.
I'll leave it there for now. There's more to explore, and another section is coming soon on some of the psychological applications/aspects with some speculation. But I wanted to get this out there to see what people think.
Nutrition and the Autonomic Nervous System
With parasympathetic dominant individuals Pottenger saw the polar opposite in terms of strengths and weaknesses within body structure as well as very different personalities."In these "sympathetic dominants," Pottenger identified a series of ailments related to their autonomic imbalance. emotionally, these patents were anxious, irritable, reactive, and easily upset, in keeping with their overly developed stress response system and high levels of circulating adrenaline from sympathetic nerve firing. Such patients tended to be disciplined and good at routines. Structurally, they were usually thin, because of their strong thyroid and adrenal function. They needed little sleep and often slept lightly and fitfully. In these patients, Pottenger reported strong muscles but terrible digestion: such patients were subject to a wide range of digestive problems such as food intolerances, ulcers, colitis, irritable bowel, chronic ingestion, and hiatal hernias."
Nutrition and the Autonomic Nervous System
He also described a third group that had a balanced autonomic system with equally strong and efficient sympathetic and parasympathetic systems and had a personality profile between the two extremes."Pottenger described these patients as calm, emotionally stable, and even keeled, very slow to anger but at times prone to depression. They were, Pottenger said, undisciplined but very creative. This group suffered degenerative musculoskeletal illnesses, as well as low adrenal and low thyroid function, correlating with their weak sympathetic tone. Such patients had a diminished capacity to deal with acute stress, and as a result of their low endocrine output, such patients could easily become overweight. Even minor stresses could be exhausting."
Pottenger considered autonomic dysregulation as the root of many diseases and disorders and that three minerals - calcium, magnesium, and potassium where primary regulators of these systems. From the introduction, "He (Pottenger) found that the administration of magnesium would suppress the sympathetic system, potassium stimulated the parasympathetic system, and calcium stimulated the sympathetic system."

The bad news for me was that the combo sent my hives into the extreme, but the good news was I had just read the following section on calcium in Gonzalez' book so it served as a strong signal to continue looking down that road.
Nutrition and the Autonomic Nervous System
Kelly came to believe, as Pottenger had earlier, that calcium metabolism was crucial to understanding the differences among the sympathetic, parasympathetic, and balanced types. Although we think of calcium as the main cement and foundation of our bones, calcium is an extremely versatile molecule. On a cellular level, calcium actually functions as a hormone, stimulating a variety of reactions within the cell. In addition, calcium is one of the major molecular components of the membranes of all cells and provides membrane stability. Kelly believed that in his sympathetic dominant patients, the excess sympathetic tone and the high levels of circulating adrenaline in these patients tended to drive calcium into the cell membranes and into the cell interior.
Contemporary physiologists now know that sympathetic action, and adrenaline, will do just this. In turn, this excessive intracellular calcium tends to produce very strong, very tight cell membranes that impede the passage of nutrients into cells and wastes out of cells. This might explain why Kelley’s extreme sympathetic dominants, presumably with the tightest cell membranes, were very resistant to allergies; their membranes served as a barrier, blocking the entry of potentially irritating molecules into the cells, as well as the release from the cells of molecules normally associated with allergic symptoms, such as histamine and serotonin. Kelley’s biochemical hypothesis helps explain why, fifty years earlier, Pottenger had noted that his sympathetic patients rarely suffered allergies.
This calcium retention he, and Pottenger earlier, observed in sympathetic dominant patients had a very important effect above and beyond cell membrane structure. For years, even in Pottenger’s time, orthodox physiologists have known that the stimulation of the sympathetic nerves requires the presence of calcium ions, and the more calcium present, the greater the sympathetic output. In effect, a strong sympathetic nervous system causes a cascade of increased calcium retention, and the increased calcium stimulates further sympathetic firing. In a similar way, the acidic environment created by a strong sympathetic nervous system tends to keep that system strong. In essence, the sympathetic-dominant system creates a biochemical environment that perpetuates its own dominance.
When talking to my allergist, one of the first things he told me that my condition wasn't an allergy. I understood this to be true because their onset doesn't come as a result of eating a specific food or being exposed to anything in particular. I had long ruled out that it was an allergy, but what stood out for me when I read the above section was that my particular type of hives are actually the opposite of an allergy, a bizarro-allergy.
In any case, I'd like to revisit Kelly's work on cancer. After he had success with his own cancer, he started seeing others with different types of cancers as well various health conditions. But he found that the vegetarian diet he was doing for himself was actually destructive for other illnesses. Through trial and error he tried different diet combinations that included raw vegetarian, cooked vegetarian, raw meat, raw meat with veggies, and cooked meat with veggies for various patients. What lead to improvement in one condition could lead to deterioration in another.
Nutrition and the Autonomic Nervous System
By 1970, Kelley began to classify his patients into three broad categories: vegetarian, carnivore, and balanced metabolizers, with subtypes within each category. Kelley developed his complex therapy out of his clinical experience. He had learned that certain patients did best on a largely vegetarian diet, others with a largely meat diet, and others with a varied diet including both plant and animal products. He learned that certain patients thrived with most of their food eaten raw and others with most of their food cooked. He learned that vegetarian patients did well with very large doses of vitamin C, magnesium, and potassium, but that carnivores did best with low doses of C, minimal if any magnesium and potassium, and large doses of calcium. Experience taught Kelley that these things were true, but on a physiological level, he did not know why.
Now this starts to get into the different types. There are a number of different physiological types which also line up with particular psychological types. I'm going to quote at length because it details the basis of a comprehensive model that describes our psychic and physiological makeup and how the two are connected.
Kelley also described, in far greater detail than Pottenger, the psychological makeup of sympathetic-dominant patients. Like Pottenger, Kelley believed that the strong sympathetic and weak parasympathetic systems in these patients could explain the observed behavioral characteristics. Sympathetic nerves, when active, produce two major hormone products, norepinephrine and epinephrine, also known as adrenaline. These two hormones act as neurotransmitters as well as hormones and affect, very predictably, many brain functions. Neurotransmitters are the signaling molecules released by nerves that allow them to communicate to other nerves, or to tissues such as muscle or the pancreatic acinar cells.
Scientists have known for more than fifty years that an injection of the sympathetic neurotransmitter epinephrine into a laboratory animal produces very distinctive reactions associated with an acute stress response. The animal becomes irritable, angry, aggressive, and prone to quick reactions and reflexes, as if the brain is on full alert. These animals have to be handled with care, as they can be unpredictably violent. In a threatening situation, such responses are clearly protective.
In humans, epinephrine enhances alertness, depresses appetite, and reduces sleep needs. During World War II, Japanese authorities fed factory workers in the war industry large doses of amphetamines, a pharmacological sympathetic stimulant, to increase productivity and reduce sleep requirements. On amphetamines, workers could easily go through twentyfour-hour shifts, barely needing breaks for food.
In his human patients, like Pottenger before him, Kelley described his sympathetic patients as irritable, prone to anger and temper outbursts. They slept poorly and lightly, but nonetheless reported excellent energy and concentration. They tended to be very aggressive and controlling, very concerned about position and dominance, all aggressive characteristics, Kelley believed, brought on by high levels of circulating adrenaline. The sympathetic-dominant mind works very fast and responds to situations quickly, oftentimes without evaluating the consequences.
Overall, in sympathetic-dominant patients, thinking tended to be linear and simplistic rather than expansive and three-dimensional. Such patients were good at rote activities requiring discipline and concentration but weren’t very creative or imaginative. They made good workers, but not innovators. In the extreme, these patients could suffer agitated depressions, with anger, insomnia, and irritability dominating the clinical picture.
Kelley described the parasympathetic dominants in equal detail. In these patients, all the tissues normally stimulated by the strong parasympathetic nerves—such as the stomach, the intestinal tract, the pancreas, the liver, and the right hemisphere of the brain—tended to be well developed and overly active. In contrast, the tissues normally stimulated by their weak sympathetic nerves, such as the endocrine glands, the muscles, the heart, and the left hemisphere of the brain, were inefficient and sluggish.
In terms of their overall body appearance, Kelley found parasympathetic dominants tended toward a rounded appearance, with large shoulders, a rounded rather than narrow facial structure, and a broad dental arch. Because of their chronic weak sympathetic nervous system tone, parasympathetic dominants usually had flabby, unresponsive muscles—just as Pottenger had described. Even mild exercise could result in severe pain, muscle tears, and hernias. And because of their weak endocrine and thyroid function in particular, these patients gained weight easily.
Biochemically, the cells of parasympathetic-dominant patients efficiently —in fact, too quickly and too efficiently—converted sugars into energy through glycolysis and the complex Krebs cycle. After a meal loaded with carbohydrates, these patients would use the sugar load so rapidly that, ironically, low blood sugar resulted. Because the brain uses blood glucose preferentially as its energy source, without an adequate supply patients can suffer fatigue, sleepiness, and depression. They tended to do far better, in terms of their general energy and well-being, when they ate fatty, highprotein foods. In these patients, proteins and fats only gradually convert into energy, allowing for a slow, steady production of ATP energy on a cellular level.
This efficient energy metabolism produced only minimal amounts of acid wastes. In addition, Kelley believed that the kidneys in these patients proficiently excreted acid molecules and tended instead to reabsorb bicarbonate—the body’s main alkaline buffer.As a result, parasympathetic cells, tissues, organs, and body fluids were very alkaline, as opposed to acid. This alkaline environment, Kelley maintained, tended to stimulate the already strong parasympathetic—and suppress the weak sympathetic—nervous systems. In a sense, the alkaline environment of a parasympathetic dominant supported parasympathetic activity and autonomic imbalance.
In contrast to the sympathetic-dominant patients, the parasympathetic cells tended to lose calcium into the bloodstream, and the kidneys rapidly excreted calcium into the urine. As a result, these calcium-deficient parasympathetic cell membranes were loose and leaky, easily allowing the influx of molecules into cells and the efflux of wastes, hormones, neurotransmitters, and other cell products out of cells. Because of these porous membranes, potential allergens easily made their way inside the cells, and the mediators of inflammation, such as histamine, easily left cells to produce the symptoms of allergy—mucus production, asthma, skin rashes, postnasal drip, hives, and irritability. Kelley’s biochemical hypothesis neatly explained why Pottenger found his parasympathetic patients to be so prone to allergic reactions.
In Kelley’s model, the personality of the parasympathetic dominant contrasted greatly with that of the sympathetic profile and could be explained by the strong parasympathetic and weak sympathetic systems. Such patients produce minimal amounts of the stress hormones norepinephrine and epinephrine that produce protective, aggressive behavior, but large amounts of the parasympathetic neurotransmitters acetylcholine and serotonin. Serotonin, the main parasympathetic neurotransmitter in the brain, has a relaxing, sedating, calming effect. Our bodies manufacture serotonin from the amino acid tryptophan, which physicians used for years as a sleep enhancer. And the Prozac generation of antidepressants work by increasing levels of serotonin in the brain, which tends to produce calm, reduce anger and aggressiveness, and improve sleep.
As a group, parasympathetic-dominant patients tend to be easygoing and friendly, enjoying the company of friends, rarely prone to anger or temper tantrums. Kelley found them usually nonaggressive, at times passive—and as a result, easily taken advantage of by aggressive sympathetic dominants. Predictably, because their levels of the aggressive sympathetic neurotransmitters tend to be low, parasympathetics don’t like confrontation. Patients in this group usually sleep very soundly and need long hours of sleep, at times ten to twelve hours. They feel best in the later portions of the day but feel groggy and spacey in the mornings.
In the extreme, these patients can suffer lethargic depressions, characterized by withdrawal and severe melancholy. In the most extreme situation, with serotonin levels far too high, these patients can become paranoid and then defensively violent. When depressed, parasympatheticdominant patients do better with sympathetic stimulants such as the tricyclic antidepressants, rather than the serotonin reuptake inhibitors.
Parasympathetics do poorly, Kelley claimed, with rote and routine, but are in general very creative and innovative in their perspectives and thinking. These patients have as a group a very well-developed right hemisphere of the brain, where three-dimensional thinking occurs. Many successful artists and creative scientists are parasympathetic dominant, Ernest Hemingway being a classic example. Undisciplined and prone to moodiness and severe depression, Hemingway enjoyed the company of friends, loved sensual pleasures, and of course was very creative in his work. Toward the end of his life, he became paralytically depressed and paranoid: unable to write and enjoy what he loved most, he ended his life in 1962.
The third general type, the balanced metabolizers, fall between the sympathetics and parasympathetics in terms of their structure, biochemistry, physiology, and psychology. Because both branches of the autonomic system tend to be equally developed and equally efficient, Kelley maintained, all the tissues, organs, and glands stimulated by the sympathetic and parasympathetic nerves—the heart, the muscles, the left and right hemispheres of the brain, and the digestive, endocrine, and immune systems —are equally developed, equally efficient, and equally strong. There is no imbalance and no dominance of organ systems.
In terms of their overall structure, Kelley described balanced metabolizers as well proportioned, neither too lean, like the sympathetics, nor overly rounded, like the parasympathetic group. Their facial structure and dental arch are ideally proportional. Their bones and muscles are innately strong and responsive to exercise, though not as responsive as the bones and muscles of the sympathetics. They can be good athletes, with training.
On a cellular level, the balanced cells efficiently produce energy through both glycolysis and the Krebs cycle, which function neither too quickly nor too sluggishly. Their cells can effectively convert sugars as well as proteins and fats into energy and can use a variety of food types equally well, unlike the parasympathetic and sympathetic extremes. Overall, these metabolizers have excellent energy and stamina, unlike the sympathetics, who tend to have excessive energy for short bursts, or the parasympathetics, who tend toward fatigue.
In balanced patients, the cells, tissues, organs, and body fluids are neither too acid nor too alkaline. The kidneys and the bicarbonate buffer systems work efficiently to keep the levels of acid and alkaline molecules under tight control. In turn, the neutral acid-base balance keeps the sympathetic and parasympathetic systems in equilibrium, with neither system overactive because of excessive acidity or alkalinity.
Such metabolizers use calcium efficiently, holding on to the mineral when needed and easily excreting any excess. Calcium enters cell membranes as needed, neither excessively nor too slowly. The membranes of balanced cells allow influx of nutrients as needed and the efflux of wastes as appropriate. If exposed to high levels of allergens in the bloodstream or body fluids, balanced metabolizer cells can respond with the release of histamine and other mediators of allergic reactions—but only if such allergens are present in excessive amounts.
The personality of the balanced types tends to be very resilient and adaptable, not prone to extremes of behavior, in keeping with their balanced autonomic system. These metabolizers produce equivalent amounts of neurotransmitters from both the sympathetic and parasympathetic systems, such as norepinephrine, epinephrine, acetylcholine, and serotonin. Balanced individuals are not prone to anger and irritability on the one hand, or depression on the other, responding with aggressiveness when appropriate yet able to relax when needed for body repair and regeneration. They need six to eight hours of sleep a night in general, though under stress they can function well with less and when relaxed can sleep more at will. The balanced types can adjust to routine as needed but can also be very creative.
In situations of stress, their sympathetic system can turn on fairly strongly —though never as strongly as in a sympathetic dominant. However, under prolonged stress, if the sympathetic system continues to fire, the balanced metabolizer patients can develop sympathetic ailments, such as digestive problems, ulcers, or colitis. If the stress persisted too long, Kelley claimed, the sympathetic system in these patients could actually wear out and shut down, leaving the parasympathetic system to take over by default. In a state of such parasympathetic dominance, the balanced metabolizers could literally change personality and develop the classic parasympathetic illnesses, such as allergies and depression.
Kelly saw varying levels of sympathetic and parasympathetic efficacy in his patients based on their nutritional needs and he came up with 10 types:
He found targeted diets for each of these types. As a rough summary, the extreme sympathetic dominant types did best on a mostly vegetarian diet with just a little bit of animal protein. The extreme parasympathetic dominant types did best with lightly cooked red meat and as much fat as possible. And then there were variations for those who fell between the extremes. I think the chart is super interesting, but there may be some variations not listed and there may be another dimension to our system to consider.

Pavlov had two overarching classifications of his dogs' reactions to stress - excitatory and inhibitory. The excitatory dogs became aggressive when exposed to a shock, and stayed in the aggressive mode long after exposure. The inhibitory dogs basically shutdown and retreated when exposed to a shock and also stayed in that mode long after exposure. He also found two additional types that rebounded fairly quickly from the shock and didn't become stuck in any particular mode. What I think is interesting is that the two extremes match with character disturbance and neurosis in humans.
All this isn't to say that all sympathetic dominant people should just be doing a vegetarian diet. The point is that we are varied individuals and the function or dysfunction of our system may very well call for specific doses of different foods at different times. I think having a dominant sympathetic system with a potentially strong secondary parasympathetic system makes things difficult to sort out, and vise versa. It's like both systems need to be fed, while not letting the other go wonky. There could be periods of needing one type of diet, and then changing to another depending on how things are balancing.
I'll leave it there for now. There's more to explore, and another section is coming soon on some of the psychological applications/aspects with some speculation. But I wanted to get this out there to see what people think.
