To review, inflammation is not the underlying root of any disease. It is a side effect of a deeper cause. In the previous article I outlined the four core causes of inflammation and discussed some potential problems and benefits of boosting the immune system by stimulating inflammation. Continuing with TNFα as an example, let’s look at the potential problems of taking anti-aging substances to reduce inflammation.
TNFα is an inflammation weapon produced by certain immune cells to protect us from viruses and cancer.
What happens when you take substances that reduce TNFα activty? Several strong pharmaceutical drugs like Humira® and Enbrel® were developed specifically for the purpose of suppressing excess activity of TNFα and relieving the inflammation of many autoimmune diseases. The immune-suppressing side effects of these strong drugs offer glimpse of what happens to the body when TNFα levels are too low. As we would expect, many of side effects revolve around the microbial kingdom gaining the upper hand. These include acute infections of the nose, throat or sinus, cellulitis, fungal infections, reactivated tuberculosis, shingles and bacterial sepsis. For those suffering from autoimmune disorders, this is a calculated risk. By shutting down inflammation, these drugs disarm the immune system so it can no longer effectively fight invaders.
Several herbs and supplements also suppress TNFα. Touted as “anti-inflammatory” or “anti-aging” these include curcumin[i], black cumin seed[ii], Boswellia[iii] and Cat’s Claw[iv]. While nowhere as strong as some of the pharmaceuticals, what happens to the body’s immune defenses when TNFα is artificially lowered? Some pathogens suppress TNFα as a way manipulate and elude the immune system[v]. Over time can moderate suppression of TNFα compromise the body’s natural defenses against overgrowth of pathogens? Since we are turning off the chemicals that cause the symptoms, how would we even know? Our current medical technology has very limited tools for detecting the presence of an invading pathogen. Most of our tools look to the immune system to provide clues about invaders. A simple urinalysis or blood test cannot detect specific pathogens. Instead it looks for high levels of immune cells like neutrophils or lymphocytes to help the physician determine what is causing the infection. By the time these immune cells show up in lab work, there has already been a significant breach of the immune system.
We know that lectins, proteins found in beans and lentils, will raise levels of TNFα. This is not because these foods have mysterious powers. It’s because the immune system mistakes them for an invader and launches an attack against them. Lectins are not inherently dangerous. However, the immune response that they elicit could certainly influence the rate of aging of any tissues participating in the reaction. Perhaps this is why the Indian diet evolved to include so many herbs that suppress this type of inflammation from immune activity. But where is the line? If there are signs of inflammation, how do we know if it is coming from a legitimate invader or if it’s an artifact of our evolution? If someone is experiencing inflammatory symptoms, shouldn’t we identify what is triggering the immune system to act before we suppress it?
An Anti-Aging Regimen Gone Awry
I felt compelled to write this after seeing an extremely healthy patient with recurrent thrush (a yeast infection of the mouth). It was fairly mild but was enough for his doctor to perform an HIV test. It was negative. This gentleman was obsessed with life extension and he was seemingly doing everything right. He was doing intermittent fasting, interval exercise, alkaline water, Paleo Diet, lots of veggies, adequate protein, low sugar and carbs, blackout curtains at night. His labs showed everything as perfect. Even his neutrophils (the immune cells that fight yeast) were on target. As part of his life extension regimen, he was paying a small fortune every month for herbs and supplements. Of interest, these included curcumin, Pterostilbene, green tea extract, fish oil, Boswellia and, when it was still available, Anatobloc®. Unless he took antifungals all the time, the thrush would come back. For awhile, I thought it was microbiome issue. A microbial stool analysis showed only mild yeast overgrowth. This was notable but not remarkable because I see these mild levels in at least 70% of the patients tested. We tried various live-shipped probiotics and fermented foods with no improvement. After a couple of months it finally occurred to me that he may have been going to far with suppressing inflammation. After some negotiating, he finally agreed to stop the Anatobloc, curcumin and Boswellia for a few weeks. Sure enough, within a week, no more thrush!
Perhaps one day we will have amazing assays to instantly identify any immune trigger that is causing inflammation. Until then how do we find that sweet spot where we suppress inflammation while still helping our immune system do what it already knows how to do?

Inflammation is not the underlying root of any disease. It is a side effect of a deeper cause. Tinkering with inflammation is tinkering with the immune system. Buzzwords like “anti-cancer”, “anti-viral”, “anti-inflammation” and “immune-boosting” are misleading and offer no information about how various herbs, supplements and pharmaceuticals actually work. Desperate for relief, ill consumers are constantly duped by the supplement industry as they seek easy answers for complex diseases. When the mechanism of a supplement doesn’t match the underlying cause of the immune imbalance, short-term side effects commonly occur. An understanding the mechanisms of aging offers us a glimpse of the potential short-term and long-term side effects that can result from tinkering with the immune system.
When I began studying functional medicine 18 years ago, I was awakened to the then controversial hypothesis that inflammation was the primary driver of many of the diseases of aging. There were hundreds of studies demonstrating the correlation between inflammation and conditions like heart disease, obesity, diabetes, cancer and even aging. As I developed my practice, it was like having magical powers believing that the cause of heart disease was not cholesterol but, in fact, inflammation. Armed with supplements like fish oil, curcumin and boswellia, I felt like Wonder Woman, striking down interleukin 6, NF-kappa B, TNFα and other inflammatory signals that could lead to disease. It wasn’t until I began treating autoimmune and skin disorders that I came to realize that inflammation is not the underlying root of any of these diseases. It’s a side effect of a deeper cause. In fact, suppressing inflammation without understanding its cause is as insane as turning off the fire alarm and going back to bed while the house fills with smoke.
There are four core mechanisms that drive inflammation. This article will explore the most common; when the immune system recognizes something as an invader and launches an attack using inflammatory chemicals as weapons. In science we call this immune system activation by antigen recognition.
The other three (listed below) will be discussed in future posts.
- Over activation of NFKappaB through dietary signaling. Activity of NFKappa B is highly influenced by the presence or absence of insulin. In general, diet doesn’t cause inflammation; it simply acts like a volume control. It isn’t until grossly pathological changes develop through excessive insulin signaling and ROS production that we begin to see the out-of-control inflammation associated with diseases like obesity and diabetes.
- Deranged methylation and acetylation of DNA,. Basically methyl groups (from SAMe) and acetyl groups are stuck to DNA to turn it on and off.
- The healing response – the redness, pain and swelling that results from an injury is ultimately an immune response that drives healing. However, repeated injuries, like when high blood pressure repeatedly damages the arteries, will lead to thickening and scarring.
Much of inflammation is nothing more than a side effect of immune activity. A fundamental flaw in our current medical approach to inflammation is the false belief that the immune system is creating inflammation for no reason. As a result, we have an entire industry of herbs, supplements and pharmaceuticals built upon the idea that suppressing inflammation is somehow healing the body. All this despite several large studies demonstrating that conditions associated with inflammation like heart disease, diabetes and cancer are mostly driven by external factors. To be clear, unless a true autoimmune condition has developed, the immune system will not act unless there is something triggering it to act. Sometimes we don’t like the results. However, this ancient system that protects us from cancer and invaders is highly intelligent and tightly regulated. The immune system will launch an attack against any critters or substance that it identifies as an invader. These include bacteria, viruses, air pollutants, some metals, environmental contaminants and oxidized LDL cholesterol. It will also attack undigested food proteins like gluten from wheat and lectins from beans. Food sensitivity tests like the ALCAT and Mediator Release Test (MRT) regularly reveal that the immune system will attack virtually any intact food protein or microbe that escapes past the protective gut mucosa (gut lining).
As one example in an ocean of inflammatory immune signals, look at what happens if we tinker with TNFα.
T= “tumor” like cancer
N=“necrosis” like death
Fα=“factor alpha” as a signal category
TNFα is an inflammation weapon produced by certain immune cells to protect us from viruses and cancer. It helps transmit signals from outside a cell to inside a cell’s nucleus where more signals tell the cell to kill itself. In science we call this apoptosis. It is helpful for ensuring that cells that have become cancerous do not survive to divide and grow into a tumor. TNFα also “serve[s] as a first-line defense against influenza virus” and has “strong antiviral activity against many viruses including avian flu and swine flu2”. Upon first glance, it sounds like anything that will increase activity of TNFα can keep you from getting cancer and viruses. Woohoo! In fact, several medicinal mushrooms are promoted as having these anti-cancer and anti-viral properties. Cordyceps,, Maitake, Coriolus and Ganoderma, all contain chemicals that increase activity of TNFα*. While this approach can be transformative for someone with a weak immune response, what effects does artificially increasing TNFα have in a healthy person? We know that in high amounts, TNFα causes considerable collateral damage to tissues. It is one of the main participants in diseases like psoriasis, ulcerative colitis and rheumatoid arthritis. Moderately high levels are associated with Alzheimer’s disease and even cancer10.
*I suspect that these mushrooms cause an increase in TNFα, not because they have magical properties, but because the immune system sees them as invaders and launches an attack.
Over the long term, does artificially raising TNFα activity accelerate the same degenerative problems that we see with any chronic inflammation? Wouldn’t mildly elevated levels still increase cell turnover, damage tissues, accelerate shortening of telomeres, speed aging and ultimately lead to early senescence*?
(*Senescence is a term used in aging research to describe the end stage of the aging process of a cell, tissue or system. When a cell reaches senescence it can no longer function properly or divide to form new cells. As more cells reach senescence in a given tissue, the more that tissue shrinks and becomes dysfunctional.)
Unless there is a specific reason to artificially stimulate TNF-alpha, it is important to weigh the potential effects of taking any herbs or mushrooms that raise it. Other herbs that stimulate inflammation by raising TNFα include Cistanches, Dipsacus, Echinacea and Psoralea. I have personally seen several patients whose autoimmune conditions were severely exacerbated from taking medicinal mushrooms. They were duped by claims and promises that somehow their condition was a result of a “weak” immune system and that these mushrooms were their salvation. On the other hand, with proper diagnosis, these types of mushrooms can be used as an effective tool when the immune response is too weak. Poor wound healing and recurrent viral infections (like shingles and Epstein Barr) are often caused by a weak immune response. Another scenario where these mushrooms may have benefit is with cancer. I have worked with scores of patients who were doing well months after their doctor prescribed Maitake-D as part of a larger protocol to help the immune system kill cancer cells. (Notice I said “part of a protocol”).
In the ocean of herbs and supplements that are supposed to help us live longer and healthier, how do we know which ones are actually helping? With illness, when the mechanism of a supplement doesn’t match the underlying cause of an immune imbalance short-term side effects commonly occur. What are the less detectable the long-term consequences? Is it possible to accelerate the aging process by inappropriately stimulating the immune system?

 From experience I have no doubt that many conditions that are diagnosed as “autoimmune” are nothing more than an appropriate immune reaction to an unidentified trigger that has grown out of control. This is commonly seen with leaky gut syndrome, SIBO and dental infections.
 Although there are hundreds of studies showing that oxidized LDL elicits inflammation from macrophages, it has never been shown whether this is an immune reaction or a healing response.

Take advantage of winter’s long hours of darkness to help your body naturally build immunity, improve fat loss, promote deeper sleep, slow cellular aging and reduce your risk of cancer . Melatonin, a well-studied hormone, is made in the pineal gland is produced in the absence of light. Minimizing your exposure to light and sleeping in total darkness helps to increase production of melatonin. As I mention in a previous post, even light shining through a cracked door is enough to dramatically plummet melatonin levels.by
A few weeks ago I published an article about Traditional Chinese Medicine and the Origin of Scientific Thought. Part of its emphasis was discussing Five Element Theory which marked the beginning of scientific medicine and a departure from Shamanism. The following is a discussion of the interconnected systems of soil biodiversity, plant ecology, gut microbiology, and human health and evolution.
In Traditional Chinese Medicine, each of the Five Elements, fire, Earth, metal, water, and wood “symbolize five different inherent qualities and states of natural phenomena” including five movements and five phases in the cycle of the seasons. People are often stumped by the fact that there are four seasons but five elements. Being the source of all life on this planet, Earth was the fifth, and viewed as the source of all the other elements.
The ancient Chinese scholars identified the digestive system to be an extension of and our connection to the Earth. After all, it is where the elements of Earth are taken in as food and are transformed into a living being.
The bacteria and fungi present in every square millimeter of soil ultimately act as the digestive system or Earth element for plants. They fix nitrogen and break down soil nutrients and minerals into forms that can be taken up by the plants’ roots. When we eat plants, we also take in some of the bacteria and fungi present in the soil. These become part of the incredibly complex ecosystem of the gut.
Each and every organism present in digestive system is a reflection of the organisms present in the soil. Each one creates its own unique signals and immune responses that literally determine our state of being on EVERY level.
We are already aware of the anti-inflammatory and immune boosting benefits of acidophilus and bifidus which are being marketed in several yogurt products. A more interesting example of this appeared in the journal, Neuroscience, in May of 2007. Researchers found that the presence of the bacteria Mycobacterium vaccae (which is common in soil and not pathogenic to humans) created an immune response that stimulated serotonin sensitivity in the certain parts of the brain. A couple of things to take note of here: First, not all immune responses are bad. They are simply signals. Secondly, this bacteria’s presence in the gut results in actual behavioral modifications via serotonin which has a happy, calming effect. Further investigation suggested that this is one reason gardening makes us happy.
Another example is the pathogenic fungus, Rhizopus arrhizus. This fungus is also common in the soil and in trace amounts in our digestive tract. Like an ecosystem, the richer and more diverse, the more resilient. As long as our digestive ecosystem is diverse and healthy this fungus remains at low, non-threatening levels and actually serves many beneficial biologic functions. For example, if you eat anything from the yam family this fungus converts some of the phytochemicals it into the hormone progesterone which is then taken up into the blood via the lymphatic system. It’s also used very effectively in German Biologic Medicine as a low-dose suppository to stimulate the body to break up its own blood clots and vascular congestion.
A broader example is the influence of Firmicutes and Bacteroidetes and weight gain in humans. An article that appeared in Nature demonstrated a strong correlation between a low level of Bacteroidetes and obesity. Conversely, thinner people had higher levels of Firmicutes. Further research showed that these bacteria directly alter carbohydrate metabolism in the digestive system.
Ultimately the bacteria in the soil determine what types plants can establish. However, after a plant establishes itself, it creates its own local pathogen controls by promoting rhizobacteria. When we eat plants and their roots the immunity from the rhizobacteria are passed on to our own digestive systems. From the soil, to the plant, to our own digestive system and back again. They are not separate. They are one system. The foods we eat have a direct impact on the preponderance of the various bacteria and fungi present in our gut. This, in turn, determines the signals and immune system responses. As a very simple example, too much sugar results in an overgrowth of some fungi like candida albicans. (more information on this in the future)
The emerging field of gut microbiology has incredible potential for treating disease. However, after all the research is done, I believe the ultimate conclusion will be that eating food grown in healthy soil with extensive biodiversity will manifest as a healthy, evolving human community. With our current technology we have only been able to culture between 0.1 and 1% of the soil fungi and bacteria. The rest is completely unknown to us.
It is important to consider the impact of microbial deprivation (via the use of bacteriocides, fungicides, irradiation, triple washing and chlorination of our food and water) on the human health and evolution. There is a growing body of evidence that suggests the immune system problems we are seeing in the younger generations are a result of insufficient bacterial and viral exposure. Furthermore, because plants determine the presence of specific bacteria, it’s important to consider the impact that monocultures have on soil biodiversity and how this affects human health.by
