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?

In the temperate zones of the Earth, late summer into autumn has been a time of celebration in many cultures. This is the time when all creatures breathe a sigh of relief as the hard work of growth slows. The cooler air transforms summer’s searing rays of sunshine into loving, golden warmth. Pregnant with sugar, fruits of flowering plants hang heavy from the branches and dapple the landscape in a mosaic of reds, blues and purples from anthocyanins and carotenoids. On the ground, combinations of lutein and zeaxanthin color the winter squashes of the Cucurbita family with the same oranges and yellows that are revealed as chlorophyll relinquishes its dominion over the foliage.

Colorful pigments that once acted as a beacon for pollinators in an array of colors and hormones[1] assume a new form that will serve as this year’s bridge of survival for numerous species of birds and mammals, including humans.

Over these precious few weeks, concentrated glucose and fructose flow in like the ocean tide. With them, the stomach’s master hormones of appetite flip flop. Ghrelin’s waxing and leptin’s waning[2] impose an ever-rising voracity of appetite that has driven successful survival of species over hundreds of millions of years. Inside the sweet goodness lurks even more treasures. Fresh omega-six oils from seeds and grains give a fresh boost to dwindling eicosanoids that are crucial for cell-to-cell communication. Vitamin E, selenium[3], vitamin C and phytonutrients stand like a levy to ensure the rising tide of inflammation doesn’t breach its banks.

In Traditional Chinese Medicine Theory, this time of year was considered the fifth season associated with the Earth element.  Warmth, sunshine, water and Earth have been magically transformed by a billion tiny seeds into a form that passes life’s nourishment unto us.   In the Jewish tradition, this season beckons the new year known as Rosh Hashanah.

“Blessed are you, sovereign of the Universe who brings forth bread to the Earth…who has kept us in life, has sustained us and brought us to this season.” Torah

Lurking deep within the cell, all the way down to the nuclear membrane, a sugar-laden surge of insulin nudges a sleeping Goddess from her torpor. 2.1 billion years ago[4],[5] some of the earliest fungi birthed this goddess and time kindly bequeathed her unto humans. In science she is known as SREBP or sterol regulatory elemental binding proteins. She is the one who, as if by magic, signals that transformation of sugar into a form that can be stored for later use as triglycerides[6] and fat[7].  Without her, most animals in the temperate and arctic zones are unlikely to survive even one winter.

Because of SREBP’s, every cell can make its own LDL cholesterol for membrane repair and vitamin D synthesis. However, without a way to supply basic antioxidants to the cell, LDL quickly oxidizes. This transformation from Dr. Jeckel to Mr. Hide damages everything it touches[8] and is considered to be one of the driving forces of atherosclerosis7. In order to protect her inner world and ensure a constant supply of antioxidants, SREBP must ask for a little help from one of her cousins in the liver, SREBP-1. While most of the cells of the body settle for glucose as an energy source, the liver engages in a more refined taste for fructose. In fact, liver cells are the only ones that can use fructose and its effects are incendiary. Fructose drives rapid production of LDL cholesterol, fats and inflammation in the liver[9],[10]. This preference for fructose acts as a supply chain for the trillions of cells’ insatiable need for antioxidants during times like these. But without SREBP, these antioxidants are useless. She alone is the key master who permits passage of these antioxidants across the cell membrane. Under the dominion of SREBP, the LDL cholesterol receptor rises to the surface of the cell like a fish rising to feed. If it is lucky, LDL cholesterol will land in its mouth. Along for the ride, precious antioxidants like vitamins A, C, and E are granted access to the cell’s inner world[11].

As this season wanes, berries hang dried and scant on the branches. Insulin recedes as the sugar festival comes to a close. The Earth cools. SREBP breathes a deep sigh as her hard work comes to an end. As she falls into her winter nap, she brings many of the creatures of the Earth with her. Only one creature has successfully escaped the dominion of this goddess. Humans innovated to store carbohydrates externally. This consistent supply of sugar drives insulin to ensure that SREBP never sleeps. Her unrelenting state of slavery drives disorders like obesity[12],[13], fatty liver[14], insulin resistance[15] and atherosclerosis[16], [17]. Perhaps this goddess would argue that these are not diseases at all but are phenotypes brought on by depriving her of a proper rest.

Phenotype (fē-nō-tīp)

noun

The net result of the interaction of an organism’s genes with its environment.

In 1953, Watson and Crick’s discovery of DNA was a beacon of hope for understanding what causes human disease. Since then science and medicine have invested billions in research and man hours under the premise and promise that understanding our genetic code would lead us to answers and cures for the leading causes of disease and death. To our surprise, the results have not been so straightforward. As we’ve gained more and more information about our genetic programming, we’ve discovered that genetics plays only a small role in the development of many of the leading causes of chronic disease and premature death. Our antiquated belief that we are destined to fall victim to a disease that ended the life of our parents and/or grandparents has given way to the sometimes difficult realization that we have more influence over the future of our health and our lifespan than we could have imagined.

As more and more research has come online, we’ve discovered that many human diseases are largely a result of external factors that are potentially under our control. A study published in 2004 in The Lancet followed over 15,000 people assessing risk factors for heart attack. The authors identified nine non-genetic risk factors that “collectively accounted for 90-94% of cardiovascular disease and had the potential to prevent the majority of premature myocardial infarction1”. These risk factors were composed of external influences that can all be eliminated including “Abnormal lipids, smoking, hypertension, diabetes, abdominal obesity, psychosocial factors, consumption of fruits, vegetables, and alcohol, and regular physical activity[i]”.

A study appearing in JAMA in 2008 on 4883 people over the age of sixty-five concluded that 90% of DM2 cases are preventable using 5 lifestyle changes. Diabetes-related risk factors include physical activity level, dietary habits, adiposity, alcohol use, and smoking habits[ii].

As our understanding deepens, it is becoming apparent that perhaps these are not diseases at all but in fact what we call phenotypes.

Since 1998, the statistics regarding cancer risk, which were studied separately by the NIH and WHO, have remained surprisingly steady. Despite thousands of new studies every year the figures stood at approximately 80% environmental (a scientific term for external factors) and 20% genetic. This was concurred in 2014 by The American Cancer Society saying, “environmental factors (as opposed to heredity factors) account for an estimated 75%-80% of cancer cases and deaths in the US[iii]. On January 2nd 2015 this assessment came crashing down with the controversial Science article by Cristian Tomasette and Bert Vogelstein titled “Variation in Cancer Risk Among Tissues Can Be Explained by the Number of Stem Cell Division”[iv]. This was an elegant, groundbreaking study that shined a light on the novel idea that some cancers simply occur because of random mutations during stem cell division. Suddenly, part of the 80% environmental aspect had to be redefined. The authors’ unfortunate choice to assign a new value to the environmental influence in the absence of adequate data parameters was incendiary across the media and scientific community. Six of the top eleven most frequently occurring cancer types were not included in this study. Interestingly, each of the excluded cancer types have a huge body of scientific evidence demonstrating that each of them is highly influenced by environmental factors. Among these cancers were prostate, breast, uterine, urinary bladder, kidney and Non Hodgkin’s Lymphoma, collectively, responsible for nearly 20% or 1/5 of cancer deaths in the US in 2014 and their incidence rate an even higher contribution3. The environmental factors that influence their development include infectious agents[v], endogenous[vi] and exogenous hormones, xenobiotic compounds[vii], certain heavy metals[viii], certain pharmaceuticals, specific industrial and organic chemicals[ix], alcohol consumption[x], glycemic control[xi], and aflatoxin[xii].

One reason the scientific community raised such a fuss about the “bad luck” cancer study was that an inordinate amount of funding and resources is already dedicated to the diagnosis and treatment of cancer. The same goes for many other “diseases” including heart disease and diabetes. After all, each one forms a massive economic base that generates billions of dollars annually. Research funding directed towards the understanding and true prevention of these diseases contributes very little to monthly recurring revenues. Instead, it represents an ominous threat to the economic base of the medical industry as well as any industry whose products might be identified as a risk. Despite the hurdles, advances in our understanding of the processes that create these “diseases” has accelerated so fast that it has created a growing chasm where science and medicine no longer overlap but have diverged. The statistics about the environmental influences on “disease” have been well known in the scientific community for at least 15 years. However, they are poorly acknowledged by the medical industry and, as a result, have remained clandestine to the general public. Chemicals aside, imagine if society truly understood how they could prevent diabetes or delay the onset of heart disease simply by adopting a regimen of glycemic control as described in the studies above. What if it was not based on a drug but was based on reducing their consumption of excess sugar? This one change would have massive reverberations through multiple industries. On one side, there would be reduced “need” for medical services that manage the entire sequela of diseases that are known to be caused by poor glycemic control. This would translate into reduced doctor visits, reduced “need” for pharmaceuticals, fewer hospitalizations, fewer surgeries, lower consumption medical supplies, reduced need for assisted living and in home care, reduction of insurance costs etc. On the other side the industrial farming and food complex would also be widely affected. This includes farming equipment, GPS equipment, chemical fertilizers, pesticides, herbicides, fungicides, GMO seeds, all sugar-laden products, packaging, transportation and distribution, fuel consumption etc.   As you can see, a significant base of the economy relies on a mutualistic relationship between Big Farma and Big Pharma. The current medical paradigm actually benefits from environmental problems and generally relegates efforts to fix this to the realm of environmental fundamentalism and quackery.

At what point do we embrace our responsibility of removing the known causes of disease? There are already billions of dollars and man-hours wasted on researching and treating diseases that are created by humans literally poisoning themselves.  What is the sense?  To continue to protect economic interests cloaked inside a societal dietary lexicon that has been hijacked by mass manipulation of naturally occurring, animalistic addictions through marketing, food additives and advertising? We must focus on removing the factors that create these disease phenotypes. Once this illusion has been cleared we can direct our resources towards novel drugs and therapies that will do the most good. Image a healthy, thriving society where disabled life expectancy is a thing of the past. Where companies and organizations like SENS, Calico and Human Longevity Inc. create drugs that don’t depend on illness but address the factors that are not under our control to produce meaningful lasting advances in  health and longevity.

In follow up to my previous post outlining concerns and conflicts to the recent “Bad Luck” cancer study, here is a technical article that I submitted to the journal Science.  For whatever reasons, they did not want to publish it.  Some of the original misinterpretations were brought about by the news editor’s summary.  Here is my original manuscript complete with references for the conflicts between conclusions and the study parameters.

This is a game changing study and its wording is of delicate importance.  Previous to this study, the NIH and CDC had concluded that 85-90% of cancer cause is due to external factors with only a small percentage being attributed to genetics.  Despite this, an inordinate amount of funding has been dedicated to detection and treatment instead of prevention. This study has the power to influence how much energy, funding and resources are dedicated to understanding and eliminating the environmental (external) causes of cancer.

Abstract:

The recent study, Variation in Cancer Risk Among Tissues Can Be Explained by the Number of Stem Cell Divisions. , published in the January 2, 2015 edition of Science by Cristian Tomasette and Bert Vogelstein elegantly shines light on the previously overlooked notion that many cancer types arise randomly from errors during stem cell divisions.

However, as outlined below, there is a significant dissonance between the study’s data parameters and the statements and conclusions set forth in the study’s title and abstract. As a member of (American Association for the Advancement of Science) AAAS, I feel it is in the spirit of science to demand clear, objective articles whose data and conclusions are congruous and are not overtly vulnerable to misinterpretation by the vast majority of the media, science writers, and the public. Of further concern, these statements could be deceiving for those making informed decisions regarding research funding and public policy.

The primary aspect of the study data parameters which lacks congruity with the study conclusions and abstract is as follows: Six of the top eleven most frequently occurring cancer types were not included in this study and are thus, not reflected in the study conclusions. Among these cancers are: prostate, breast, uterine, urinary bladder, kidney and Non Hodgkin’s Lymphoma, collectively, responsible for nearly 20% or 1/5 of cancer deaths in the US in 2014 and their incidence rate an even higher contribution.[1] There is a substantial body of evidence demonstrating that each of these omitted cancer types is highly influenced by a variety of environmental factors. These environmental factors include infectious agents[2], endogenous[3] and exogenous hormones, xenobiotic compounds[4], certain heavy metals[5], certain pharmaceuticals, specific industrial and organic chemicals[6], alcohol consumption[7], glycemic control[8], and aflatoxin[9]. Per the American Cancer Society (ACS), “environmental factors (as opposed to heredity factors) account for an estimated 75%-80% of cancer cases and deaths in the US.”[10] Although we may eventually find that these environmental factors drive accelerated “random” error events, it is not possible to draw an objective, statistically meaningful conclusion about environmental and heredity vs. “random” influences on cancer as a whole based on the limited data parameters set forth in this study.

Although the aforementioned cancers types (excluded from the study) are presumably part of the one-third of “tissues [that] were not included in [the] analysis”12, their predominance represents a substantial and statistically significant percentage of cancers in the US. It is understandable that “the requisite parameters were not found in the literature or [their] estimation was difficult to derive”12. However, in light of these major exclusions, the conclusions drawn by the authors in the title and in the abstract of the paper should reflect this gross exclusion. Because the exclusion is not highlighted, the stated study conclusions are ambiguous and, as we have seen in the media, are vulnerable to misinterpretation.

Furthermore, the random cancer incidents demonstrated in the study do not parallel the incidence of various cancer types reported by the CDC and NIH. In some cases, like lung and colorectal cancer, they are flip-flopped. This suggests that influences exist outside of the random events like immunity[11] and well-known tumor suppressor genes, which are not accounted for in the study. The article should clarify that the study conclusion merely represents a statistical probability of a random cancer cell events in a given tissue type over a lifetime but does not represent the ultimate fate of any cancer type or cell. The data presented from the study does not provide sufficient evidence for the following statement in the abstract:

“These results suggest that only a third of the variation in cancer risk among tissues is attributable to environmental factors or inherited predispositions. The majority is due to “bad luck,” that is, random mutations arising during DNA replication in normal, noncancerous stem cells. This is important not only for understanding the disease but also for designing strategies to limit the mortality it causes.[12]

Did the authors intend that their conclusion was based only on “tissues” that were included in their study? Or were they implying that “only one third of [all] cancer risk is attributable to environmental factors or inherited predispositions?12” Below is a sampling from hundreds of various headlines from six prestigious media organizations that understandably misinterpreted the conclusion of the study article.

“Most cancers are ’caused by bad luck – not lifestyle’: Scientists claim 65% of cases are down to random mistakes in genes that we can do nothing about” Jenny Hope of the Daily Mail Jan. 1 2015

“Two-Thirds of Cancer Due to Bad Luck, Study Finds” by Mary Elizabeth Dallas of CBS News reported Jan. 1 2015

“Most cancers are caused by bad luck not genes or lifestyle, scientists say.” By Sara Knapton for the Telegraph Jan. 1 2015

“Bad luck of random mutations plays predominant role in cancer”. Science Daily Jan. 1 2015

“Scientists: Random Gene Mutations Primary Cause of Most Cancer” by Ben Brumfield on CNN

“Biological bad luck blamed in two-thirds of cancers” by Will Dunham of Reuters

******

In addition to the ambiguity of the abstract, the title implies the study is based on overall cancer risk. It would be more accurate to change the wording from “cancer risk” to “some cancer types”.

Of further concern, the authors also make recommendations that could influence the direction and funding of research and public policy. Because of the excluded types of cancer and overall data, the following statement from the article is not scientifically objective and should be removed or clarified:

Moreover, we show that these stochastic influences are in fact the major contributors to cancer overall, often more important than either hereditary or external environmental factors.”

The authors go on to conclude that,

“These results suggest that only a third of the variation in cancer risk among tissues is attributable to environmental factors or inherited predispositions.”

Although compelling, it is premature to assign exact figures and conclusions based on such limited data.

Ultimately, because of its limited data parameters, this study lacks the merit necessary for forming decisions around research funding and public policy. The broad statements in this article could be misinterpreted by non-science policy makers potentially leading to uninformed decisions about a wide range of issues from allocation of research funds to public health recommendations.

Because the media headlines were so grossly misinterpreted and misleading to the public, corrections and clarifications should be made available as a press release. This act would be in the interest of the integrity of the scientific community and in good faith to the non-science public.

Did you know some plants like grape, rice and lotus, have more genes than humans?  This is contrary to the fundamental thought that humans, being the “most” evolved, should be biologically more complex and therefore possess more genes.  How can this be you ask?  The current hypothesis is that we come equipped with a significant amount of genetic material from the organisms growing inside our gut.  These various bacteria, fungi, parasites and viruses provide signaling for the inner workings of our entire body.   They support immune function, moderate inflammatory responses, generate vitamins that we are not capable of making, produce hormones from some of the foods we eat, help us to absorb minerals, and regulate the production of neurotransmitters.  Most importantly, they allow our immune system to remain competitive with the rate of evolution of pathogens. Average bacteria have 500,000 generations for each human generation.  Humans have only had 350-400,000 generations since the appearance of the earliest hominids in Africa.  A team of researchers followed the changes of a genetically similar population of E. Coli for 50,000 generations.  At 10,000 generations, a short time from an evolutionary perspective, “…the evolving genomes became increasingly different from their ancestors.  Moreover, tremendous diversity accumulated within each population, such that almost every individual had a different genetic fingerprint” (Papadapoulus PNAS 1998)

Some surprises emerged at the 50,000-generation mark.  One population had evolved to be able to utilize a completely different energy (food) source.  Others changed in size, shape and antibiotic resistance.  The successive generations were generally more resilient than the previous generations.

The human microbiome is passed on from generation to generation as an infant passes through the birth canal.  The mixing of the mother’s secretions, including feces, provides the inoculation of these beneficial bacteria and fungi.   The genetic material that we are carrying inside us today has evolved since the beginning of time and has been passed down through thousands of generations.  Most animals on the planet, including many (and possibly all) born through eggs , receive this life-giving inoculation from their mother.

Over the past few years, we have observed a significant increase in autoimmune conditions, exaggerated immune responses, Celiac disease, allergy and asthma.  Various factors have been attributed including lack of vitamin D, lack of sufficient parasites, an excessively sterile environment and deficiency of multiple bacteria, some of which are considered pathogenic.  As I mention in my previous article, a lack of H. pylori, the bacteria that can cause stomach ulcers, can manifest as asthma.  We are seeing startling changes to the human microbiome.  Many individuals now require fecal transplants to replenish some of these missing organisms or face chronic illness.  This is replacing what should have been passed down through the birth canal.  Simply replacing these bacteria with fermented foods or probiotics is not always adequate.  There are two reasons for this.  First, like the soil, we have only been able to culture and identify only 1% of the organisms growing in the human digestive system.   We don’t yet have enough information to re-create such a diverse system.  Second, there is a hierarchy to the establishment of bacteria in the gut.  E. coli, are like top soil on bedrock.  They create a matrix for all the other single-celled creatures to grow and thrive.  You can drink a gallon of yogurt daily but if E. Coli is not present, other beneficial species cannot establish themselves.  So why not simply replace the E. Coli?  Here’s the catch.  Most E. Coli strains from other people and animal’s are rejected by our body’s immune system.  This is likely why fecal transplants, which can work miracles, but must be obtained from the mother or siblings to avoid complications.

There are hundreds of studies linking cesarean sections (c-sections) and chronic antibiotic use with various autoimmune conditions and other health problems.  Here are a few.

  • A large study demonstrated a 52% increased risk of asthma in children delivered via cesarean section.
  • Another study demonstrated a 2 fold increase in allergic reactions, asthma and sinus issues (J Allergy Clin Immunol 2008;122:274-9.)
  • A meta-analysis (a study that looks at all studies on the same subject) revealed 19% increase in type 1 diabetes in children who were delivered via c-section.
  • A study demonstrated significant reduction of TNF-alpha inflammatory response in piglets infected by Mycoplasma hyopneumoniae if they were inoculated with commensal bacteria.  ***The fact that bacteria moderate inflammatory responses during infection could easily explain the increased incidence of severe allergic reactions.
  • Another study demonstrated a significantly increased incidence of Celiac disease in children born via C-section
  • Here is a wonderful article summarizing many of this information http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3110651/#R47
  • Here is a book that goes into detail about some of these findings and their implications: An Epidemic of Absence  – New Ways of Understanding Allergies and Autoimmune Diseases by Moises Velasquez-Manoff

These facts have sparked interest in the scientific and medical communities regarding the practice of cesarean section and antibiotic use.  Less well recognized is the detrimental influence of seemingly harmless chemicals upon the microbiomes of various species.  In 1974 the miracle herbicide, glyphosate or Roundup ™ was introduced to different agricultural markets in Malaysia, the U.K. and the U.S.   Back then, techniques for evaluating the safety of chemicals was primarily based on two aspects.  First, was the chemical’s ability to create disease.  Second, the dose of the chemical that caused death in 50% of the recipients. (the LD50).  Until recently, all studies on glyphosate suggested that most animals could literally drink the stuff without ill effects.  However, as our knowledge and research techniques have evolved, we are discovering that we may have made committed irrevocable and possibly unprecedented mistakes in introducing this chemical into our environment.

A study performed on the bacteria populations in the digestive systems of poultry demonstrated that glyphosate caused significant reductions in the populations of various species of beneficial bacteria including Enterococcus faecium, Bacillus badius, Bifidobacterium adolescentis and Lactobacillus spp.  (As I referenced above, we now know that beneficial bacteria are passed from the mother hen to her offspring and are inside the developing embryo within the egg).  The reduction of these beneficial bacteria allowed overgrowth of bacteria that cause disease in humans like typhoid and botulism along with various other strains of salmonella.

As these pathogens have become more and more prevalent, we have had to use more and more antibiotics to protect ourselves from foods that have been part of the human diet for generations.  Of course, the increased antibiotic use has further reduced the populations of the bacteria that prevented the pathogens to begin with.  As time passes the pathogens develop more and more resistance to the antibiotics.   We’ve replaced a system that worked for thousands of years with a scenario where we must innovate or die.  I predict that in five to ten years we will come full circle and use bacteria and fungi as a replacement for antibiotics and to replenish what has been lost.

All of the beneficial bacteria mentioned in the study above are the same ones that exist in the human digestive system.  As I have discussed in previous articles, the bacteria residing in our digestive system are reflective of the bacteria growing in the soil.  Similar species of Enterobacter, Pseudomonas, Bacillus and Enterococcus are found both in the soil and in the human GI tract.

The world’s grasslands contain within them the highest level of microbial biodiversity of any other soil or ecosystem on the planet.  Over millions of years this biodiversity created the dark, deep rich soil that made the Midwest of the United States one of richest resources for food production on the planet.  The introduction of glyphosate allowed humanity to produce more food than has ever been possible.  However, it is possible that it has already altered our evolutionary path.  Dr. Don Huber, Professor Emeritus of Plant Pathology, Purdue University has studied various aspects of soil microbiology and plant pathology for decades.  Here is the perspective he offered regarding glyphosate in an interview a few years ago.

“All it does is make it possible for that plant to survive and to accumulate more glyphosate. We still change the soil ecology, microbial ecology, and… our intestinal microbiology.” 

Daily discoveries demonstrate that human health is inextricably linked with the health of the tiniest aspects our environment.  Through innovation we have overcome many of Nature’s obstacles to create abundance and, for now, have become one of the most successful species on the planet.  Through our knowledge we are finding new crossroads where it is obvious our actions are interfering with our own ability to adapt and evolve.  It is becoming imperative that we use this knowledge to restore balance to correct the mistakes we have made.  Otherwise, we will back ourselves into a corner where innovation is no longer about advancement but obligatory for our own survival.

With the best of intentions are we slowly rendering our population incapable of developing natural, adaptive immunity?  In his upcoming book, Doc, Terry Grossman M.D. gives a powerful example of this as he discusses the pros and cons of vaccines.  I would like to expand on the subject.

In 2005, a study by W Katherine Yih et al, was published demonstrating that from 1998-2003 “As varicella vaccine coverage in children increased, the incidence of varicella (chickenpox) decreased [by 79%] and the occurrence of herpes zoster (shingles) increased [by 90%]”. These figures are beyond statistically significant.  Similar trends were observed in several areas where the varicella vaccine was initially introduced.  The explanation for the unexpected emergence of shingles was this.  In any given population, there would have been an ongoing percentage of people with active varicella infection.  Chronic, low-grade exposure to the virus throughout the population ensures that it remains on the immune system’s “radar screen” and is therefore kept at bay by our own adaptive immunity.  Vaccinations work in a similar fashion.  Another study done by Bryson et. Al. predicted that “a substantial increase in herpes zoster cases over the first 30–50 years after the initiation of mass vaccination, peaking about 20 years after the start of mass vaccination at an incidence of 51 percent over the pre-vaccination level and eventually falling below the initial incidence”. doi: 10.1016/S0264-410X(02)00180-9  Another study conducted in Germany also concluded there was sufficient evidence to suggest that varicella vaccinations lead to higher incidents of herpes zoster in the older population.

To be objective, before 2003, herpes zoster was not identified as a nationally notifiable disease, and no states in the US required reporting of cases.  The study mentioned above seems to have accounted for record discrepancies within the chosen test site.  However, a study came out in 2008 doi: 10.1086/522162 demonstrating that some areas where the varicella vaccine was introduced saw minimal change in reporting of herpes zoster cases.  There is one claim in this study that I take major issue with. They state “Evidence from population-based studies suggests that rates of HZ [herpes zoster] were increasing in the United States before the introduction of the varicella vaccination program.”  Another study  states that the incidence of herpes zoster has been increasing since 1945.  In both of these studies, several crucial data points were not accounted for.  First, there was no oversight or requirement in reporting of herpes zoster events before the introduction of the vaccine in 1995.  Second, access to health care has increased between 1945 and the present.  Reports of incidents would not have been consistent through any subsection of the general population.  I’m not saying they don’t have some valid points but in a scientific paper, these are presumptive and irresponsible statements.  Their conclusion should have been that the data is inconsistent and not available.

There are always unknowns.  However, the current research suggests that the introduction of the varicella vaccine saved an average of 90 lives per year and created an anthropogenic chasm in an entire system, between virus and human, that had evolved over the millennia to reach a steady state.  Trends like this have the potential to remove human beings from the interconnected web of Evolution and Natural Selection.  In this way, technology loses its place as a luxury and instead becomes a necessity of human survival.

I will be traveling to Mongolia for a few weeks and don’t expect to have the ability to do any posts. With regards to my series on Sugar’s Contributions to the Evolution, Then Devolution of Humans.   I would like to leave you with a story that demonstrates why it has taken so long for our society to become informed about the adverse health effects of sugar.  Before I start, I would also like to add that when I was traveling through Ecuador a few months ago, every medicine man and shaman that I met said one of the best things you can do to keep your people healthy is to minimize sugar.  They understood that fruit sugar was the same as any other sugar. It’s amazing to me that they didn’t require any scientific evidence for this.  They simply understood.

A few months ago, our nurse practitioner was following a study that was supposed to show that fructose, specifically from agave, had no adverse health consequences.  At the time, she was admittedly hopeful about the outcome because she loves sugar and was convinced that fruit sugar, because it’s natural, couldn’t be that bad.  The study looked at healthy individuals as well as type 2 diabetics.  Each group consumed a controlled amount of agave syrup daily in addition to their regular diets. After just a few weeks the researchers had to abandon the study because the blood markers in both groups (fasting glucose and hemoglobin A1C) continuously rose.  In the diabetics, the numbers reached unsafe levels.  Since the intention of the study was to show that fructose from agave was safe, nothing was published and this valuable information never made it into the scientific literature.

This is a photo of Intipaxi, a traveling healer, whom I met in Ecuador.  He would visit villages and teach the people how to use their local plants medicinally and how to keep themselves healthy. He continually talked about the importance of sunshine and walking barefoot on the Earth.

Overconsumption of any sugar has deleterious effects on our health.  However, of the primary types of sugars that our cells can utilize; glucose (common in root vegetables and grains), fructose (common in fruit, honey, agave and corn) and galactose (common in legumes and milk) I propose that fructose has the most detrimental effects on human health. Unlike glucose, which is metabolized by most cells as an energy source, fructose is mainly metabolized by liver cells.    As I mentioned in my last post, a study appeared way back in 1988 in the Journal of Diabetes Research and Clinical Practice that showed fructose has a reaction constant 7.5 times higher than glucose as well as a much higher calculated biohazard rating.  Supporting research has increased exponentially since then.

In small amounts AND in the presence of adequate antioxidants, the liver has no problem metabolizing fructose.  In fact, it converts it into glycogen which is the primary fuel for anaerobic muscles (the ones that get really big when you lift weights).  Any fructose left after the muscles have had their fill of glycogen is converted into triglycerides.  These “feed” fat cells for later use.  Depending on which study you read, this occurs if more than 5-7 grams of fructose is consumed in one sitting. In addition to being converted into triglycerides, the excess fructose initiates a damaging, inflammatory response in the liver along with producing elevated levels of free radicals known as reactive oxygen species (ROS).

Here is a brief summary of the amounts of sugar contained in one cup of various fruits and beverages:  Please note that I couldn’t find a breakdown of the glucose to fructose ratio.  Source: http://nutritiondata.self.com/

  • Coke                      (26g sugar) – almost all fructose
  • Bananas               (28g sugar)
  • Apples                 (13g sugar)
  • Apple juice         (24g sugar) – 15 grams of fructose
  • Grapes                 (23g sugar)
  • Apricots               (14g sugar)
  • Cherries               (15g sugar)
  • Grapefruit            (17g sugar)
  • Cantaloupe         (14g sugar)
  • Pears                     (16g sugar)
  • Plums                    (16g sugar)
  • Blueberries         (15g sugar)
  • Blackberries       (7g sugar)
  • Raspberries        (5g sugar)
  • Peaches               (13g sugar)

At first, the inflammation and free radical activity initiated in the liver from fructose results in fat accumulation inside the cells and mildly reduced function. If it continues along this path for any amount of time, a condition called non-alcoholic fatty liver disease, NAFLD, develops.  Scores of studies demonstrate that along with obesity, NAFLD incidence has been steadily rising in Westernized, developed countries and in counties that are becoming developed.   A study showed a 10-year doubling of NAFLD in one Chinese Population and demonstrated that a similar trend was seen in both Korea and Japan.

Note:  I thought it would be interesting to compare fructose consumption and NAFLD incidence in various countries.  I spent several hours and had a research assistant spend several more hours trying to find information on fructose sales or consumption in various countries. The information is very difficult and seemingly expensive to obtain.  If anyone has access to this type of information, please contact me or enjoy the dissertation subject. 

I would like to point out that many of these studies are performed by checking serum levels of the liver enzymes ALT and AST.  The pathological changes occur way before these enzymes levels begin to rise.  According to Dr. Michael Cave, a professor of hepatology, gastroenterology and nutrition at the Univerisity of Louisville, ALT and AST parameters should be much lower because these enzymes only begin to increase long after the inflammation and fat accumulation starts.  To be objective, Dr Cave also presents a strong case for an increase in fatty liver disease as a result of chronic exposures to several persistent organic pollutants  and xenobiotics.  Several studies show that exposing liver cells to fructose, then adding a xenobiotic, results in accelerated inflammation and disease.  It is possible that the rise of fatty liver disease has been a combination of increased fructose intake and exposure to these various environmental pollutants that are now ubiquitous in our environment.

Depending on which study you read, NAFLD is seen in 10-24% of America’s general population and 57-74% of obese individuals.  According to the Mayo Clinic’s website, they describe fatty liver disease as “common and for most people causes no signs, symptoms or complications”.  However, long before any physical symptoms present, the liver’s various functions diminish.  If this continues permanent liver damage occurs along with the cumulative toxicity effects of secondary dysfunction.  In addition, any persistent organic compounds that aren’t removed from the blood by the liver accumulate in fat tissue.

Here is a brief summary of the main functions of the liver:

  • Eliminating endogenous toxins like testosterone and estrogen
  • Eliminating exogenous toxins like gasoline vapors, prescription medications, pesticides, artificial fragrances, hormones from birth control usage that are now in the water supply and BPA from the PVC pipes that carry our water.
  • Generating antioxidants like glutathione which not only carry out Phase 2 detoxification in the liver but neutralize pollutants in the lungs and assist with the recycling of neurotransmitters in the nervous system
  • Metabolizing fat along with various types of cholesterol
  • Generating proteins and enzymes for physiological functions all over the body

It makes me cringe to think what is happening to the livers of those poor souls who become motivated to lose a few extra pounds.  They go running five miles per day, lift weights then drink a bunch of carrot juice or eat a banana because they’ve been misinformed into thinking it’s healthy.  Not only are they putting an extra burden on their liver to metabolize the fat that is being burned, they also have to detoxify the various persistent organic compounds that are released from that fat.  For the final assault they add massive doses of fructose.  It would be really interesting to check the liver enzyme levels on NBC’s “The Biggest Loser” contestants before and during the competition.  If I were them, I would do things to support the poor liver like eating more protein and vegetables, getting rid of the fruit and adding supplements like phosphatidylcholine, folic acid, B6, B12, alpha lipoic acid and N-acetyl cystiene.

Clearly, we evolved with the ability to eat fruit.  For the next post in this series, I will discuss this seeming idiosyncrasy along with how the rise of fructose consumption is causing us to devolve.

Before I begin this first section of my series on sugar, I would like to note that I usually provide references for everything I write.  The information below is based on my daytime profession and years of assembling research.  It would take me too long to find all the references.  However, most of the facts on physiology can be obtained from any basic cell biology book. There are also several books available that are well-researched with solid references.  Here are a couple:  Transcend by Terry Grossman M.D. and Ray Kurzweil and The Zone by Barry Sears.

In our medical office where I’ve practiced longevity nutrition for over ten years, the term “The White Satan” (conceived by Terry Grossman, M.D.) is used synonymously with sugar.  Efforts to educate our “ever-expanding” population about the powerfully, deleterious health effects of sugar consumption have been like turning the Titanic.  The information has been clear and out there for at least 12-15 years but the emergence of sugar-induced obesity and its accompanying diseases; diabetes, high blood pressure, fatty liver disease, heart disease etc. has continued to increase in numbers.  The average age of people affected by these diseases has been falling steadily and it is no longer uncommon for teenagers to be diagnosed with type 2 diabetes.  Several factors have contributed to this trend.

  • Sugar’s highly addictive nature
  • The emergence of an entire monoculture-based industry providing the public with cheap, foods and  sweetened drinks packed full of high-fructose corn syrup
  • The false belief that fruit and fruit juice is healthy
  • Emphasis on starches and fruit on the Food Pyramid
  • The non-evidence-based, low-fat revolution which led people to believe that anything that didn’t contain fat, especially saturated fat, was good for them
  • Slow, weak and uninformed efforts to educate the public

Any time the level of sugar in the blood surpasses what the cells are capable of managing several problems occur. 

  • Inflammation – the hormone insulin is released by the pancreas into the blood to enable our cells to turn sugar into energy.  We obviously need insulin to survive.  However, excessive levels tend to magnify any inflammatory responses that are happening in the body.  In addition, sugar itself, especially fructose, causes direct inflammation in the liver.  Simply eliminating sugar from one’s diet will almost always result in improvement of inflammatory conditions like asthma, acne, and even back pain.
  • Elevated triglycerides – Insulin signals the liver converts excess sugar floating around in the blood into triglycerides.  Unless you possess a rare, genetic disorder, elevated blood sugar is the ONLY physiologic mechanism for producing triglycerides.
  • “Feeding” of fat cells – Triglycerides floating around in the blood are the direct contributor to “feeding” fat cells.  The higher the blood sugar goes, the higher the triglycerides and the faster weight gain occurs.
  • Immune system dysfunction – As pointed out in Transcend, excess sugar interferes with the ability of white blood cells to utilize vitamin C to carry out a proper immune response
  • Intestinal Dysbiosis – Excess sugar changes the body’s terrain, feeding and promoting overgrowth of yeast along with unbeneficial and some pathogenic bacteria.  The inflammatory response that results from the immune system fighting these critters has an effect on the entire body.  It can manifest as various diseases as the inflammatory chemicals make their way through the lymphatic system. 
  • Advanced Glycated Endproducts (AGE’s) -Glycation is a caramelizing, chemical reaction that occurs when sugars come into contact with proteins.  This reaction can be demonstrated easily in a Petri dish or seen when we bake a chicken and the skin becomes brown and crispy.  The same thing happens to our tissues upon exposure to sugar.  Glycation causes gumming up of enzymes and tissues which render them functionless. 

**Good story:  When I was in college, a gross human anatomy class was lucky enough to have an elderly lady as their study subject.  One of the first things the professor pointed out was the amount of glycation in her tissues.  If you sliced through a piece of her lung or liver, it was never difficult to find these areas of brown, crispy, glycated tissue.  Many age spots are the result of glycation.

It is important to know that these “excess” levels of sugar occur when a healthy human consumes more than 5-7 grams of sugar within a given meal.  Diabetics can tolerate 0-5 grams depending on the severity of their insulin resistance.   The glycemic index  is a useful gauge of how quickly a food raises blood glucose levels.  For example a medium, white potato releases glucose into the bloodstream very quickly and is the equivalent of eating 26 grams of sugar.  The glycemic load  is a measurement of the net glucose-release into the system.  For example, if you eat just a bite or two of that high-glycemic potato, the blood glucose goes up just a little.  I’ve noted that most of my readers are incredibly sophisticated in the thinking and I’m sure most have known about the glycemic index and glycemic load for more than a decade.  However, if you somehow missed out, I strongly encourage you to familiarize yourself with it and take it seriously. One teaspoon of sugar is approximately 5 grams. One teaspoon of honey is 6.5 grams of sugar.  A banana contains 28 grams of sugar. 

Here is a link to the most dangerous foods in America http://www.rense.com/general91/20_Worst_Drinks_in_America_2010.pdf

A severe misconception that has resulted from the spotlight shining on the glycemic index is that fruit and fruit sugar is healthy and safe because it has a low glycemic index.  Fruit contains a completely different sugar, fructose, which cannot be measured with a glucose meter.   A study appeared way back in 1988 in the Journal of Diabetes Research and Clinical Practice that showed fructose has a reaction constant 7.5 times higher than glucose as well as a much higher calculated biohazard rating.  Since then, there is a 1000 fold increase in the research that confirms these findings about the dangers of fructose. This information is just reaching the fringes of the mainstream now.  How sad.  In the next post, we will explore this further and then go on to discuss how the emergence of fructose in the Western diet has led to a rapid devolution.  Later I will present a hypothesis that fructose availability was a primary contributing factor to lifespan and longevity throughout the evolution of humans.

Human beings constantly strive to be more than what we think we are.  We look outside of ourselves for the next thing to make us smarter or younger, stronger or live longer.  This yearning has given birth to the multi-billion dollar industry of nutritional supplements.  We are subject to a continuous stream of advertising and information on the next great discovery.  If you drink this berry juice from the Amazon you will live longer!  Take this new antioxidant discovered in these roots from some exotic part of China!

What are we really discovering?  That the fruits and roots and herbs and leaves that come from our Earth are good for us? These are not new discoveries.  The discovery is that these foods are what we should be eating!  From red wine to tobacco, amazing health-giving qualities can be found in any real food that we consume.  The ancient civilizations like China and India have known this for hundreds if not thousands of years.  Their diets have evolved to the point that their day to day meals are their medicine.   

Let’s take the seemingly miniscule example of folic acid.  Its name is derived from its source, foliage.  One study after another has shown the incredible health-giving benefits of folic acid.  To name a few:  reducing the incidence of birth defects, reducing the incidence of lung cancer in smokers and several other types of cancer, reducing the risk of Parkinson’s disease, and increasing fertility in both men and women. I can’t tell you how many women I have seen for infertility who became pregnant within a month of two of taking large doses of folic acid along with B6 and B12.  Folic acid has perhaps a couple hundred biochemical functions in the body.  One of the more interesting is its ability to turn genes off by giving up (donating) part of its chemical makeup known as a methyl group. (many other vitamins and substances do this as well). 

In the emerging field of epigenetics one of the most mind-blowing experiments done to date was with Agouti mice.  Scientists use a genetic strain of mice known as “Yellow Mice” which have a high risk of cancer, diabetes, obesity and reduced lifespan to study these very diseases.  They discovered that when they fed pregnant “Yellow Mice” folic acid, not only did the offspring look completely different (leaner, brown-gray fur, etc) but even feeding the offspring the same disease-inducing diet as the “Yellow mice”, the offspring had lower incidences of cancer, obesity, diabetes and lived longer!  This “new” strain of mouse was called the Agouti mouse even though it was genetically identical to its predecessor.  Discoveries like these in epigenetics are forcing scientists to reconsider major theories like “nature vs. nurture” and certain mechanisms in the theory of Evolution. 

On the flip side a few studies have come out recently showing that folic acid supplementation increases the incidence of some types of cancers especially in the prostate.  We have to consider that everything in nature functions as part of the whole.  When we eat green, leafy vegetables we receive not only folic acid but also an array of B vitamins and trace minerals which so often function with folic acid in the body.  We also receive hundreds of plant chemicals that alter how our genes control our immune systems, detoxification pathways, etc.  This is what we evolved with. The more we delve into the awesome intricacies of Mother Nature, we reach two realizations.  (1)How little we know.  (2) We already know everything because we evolved with it and are a part of it. 

So what it the conclusion I am asking you to come to today?  Is it that you should take more folic acid?  Perhaps it’s not that taking large doses of folic acid is good for us.  It’s that NOT consuming it in the amounts and forms that we evolved with is making robbing us and our progeny of our health and vitality.  Imagine living before farming.  What do you think you would eat in the springtime?  Look around at what is emerging from Earth.  What are you made of?
