Five Important Facts About Cancer That Nobody Ever Talks About

Published

on

It’s hard to believe that approximately one in every two people will develop some form of cancer within their lifetime. As a result, cancer awareness has skyrocketed. Millions of people around the globe are helping to raise money and awareness for cancer and cancer treatment. This overwhelming support from the public just goes to show how many good hearts are out there, and in no way should we dismiss that generous spirit. There are, however, some important facts relating to this disease about which many people are still unaware.

While it is of course disturbing that cancer rates are at all time time high, the prevalence of this disease is causing people to take notice and to question, which is always a good thing. People are becoming more aware of the disease, looking into alternative treatment options and trying to determine the cause of this illness. People are starting to wonder why so many of us are so sick. So despite how gloomy it may appear, there is hope for all of us.

The 5 facts about cancer below are indeed disturbing, but what’s even more disturbing is the fact hat nobody even talks about them. If we want to get to the root of this disease, ignorance is not the answer. Hopefully this article helps you learn some important information about cancer that you probably won’t hear much about in the mainstream.

Questionable Cancer Research/Fraud

Linus Pauling, Ph.D, and two time Nobel Prize winner in chemistry, has revealed: “Everyone should know that most cancer research is largely a fraud, and that the major cancer research organizations are derelict in their duties to the people who support them.” (source)(source)

He is considered one of the most important scientists in history. He is one of the founders of quantum chemistry and molecular biology, and was also a well known peace activist. He was invited to be in charge of the Chemistry Division of the Manhattan Project, but refused. He has also done a lot of work on military applications, and has pretty much done and seen it all in the scientific field, so his words are not to be taken lightly.

And it’s not just Pauling making these kinds of statements. Many other well respected scientists, who are definitely in a position to know about this type of thing, have made similar statements. For example, Dr. Marcia Angell, a physician and longtime Editor in Chief of the New England Medical Journal (NEMJ), which is considered to be one of the most prestigious peer-reviewed medical journals in the world, said that:

It is simply no longer possible to believe much of the clinical research that is published, or to rely on the judgement of trusted physicians or authoritative medical guidelines. I take no pleasure in this conclusion, which I reached slowly and reluctantly over my two decades as an editor of the New England Journal Of Medicine. (source)

Dr. Richard Horton, Editor in Chief of another one of the world’s most best known medical journals, The Lancet, recently published a statement expressing that a large quantity of published peer-reviewed science is actually completely false. He revealed:

The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue. Afflicted by studies with small sample sizes, tiny effects, invalid exploratory analyses, and flagrant conflicts of interest, together with an obsession for pursuing fashionable trends of dubious importance, science has taken a turn towards darkness.  (source)

A lot of the ‘credible’ research out there has been supported and funded by the pharmaceutical companies themselves, and much of it conflicts with the work of independent scientists from all over the world.

The field of U.S. cancer care is organized around a medical monopoly that ensures a continuous flow of money to the pharmaceutical companies, medical technology firms, research institutes, and government agencies such as the Food and Drug Administration (FDA) and the National Cancer Institute (NCI) and quasi-public organizations such as the American Cancer Society (ACS). – Ralph Moss, Ph.D., quoted by John Diamond, M.D., & Lee Cowden, M.D. in Alternative Medicine: The Definitive Guide to Cancer

People Are Actually Having Success With Alternative Treatments

A growing trend amongst people who have been diagnosed with cancer is to seek out alternative treatment, and this is largely because so many people have reported solid success rates. We can also attribute this shift to the vast amount of published scientific literature pointing people in this direction. For example, here is a quick video clip of Dr. Christina Sanchez, a molecular biologist who explains the power of THC. Other ingredients within cannabis have also been shown to annihilate cancer tumours.Here is an older article with just a few out of hundreds of studies sourced, just to give you an idea. It’s worrying that no human clinical trials have been conducted on the use of cannabis to treat cancer, despite the fact that scientists have known for decades that it is effective.

Mykala Comstock is a wonderful example of cannabis’ efficacy; she had T-cell acute lymphoblastic leukaemia, a very rare and aggressive form of childhood leukaemia. In July of 2012, doctors discovered a basketball-sized mass of lymphoblasts in her chest. Her mass was so large that she was not able to be sedated for risk of death from the pressure on her esophagus and heart.

More people are to turning to other herbal remedies as well. Research has shown that artemisinin, found in various plants, can also kill cancer cells.

Dietary changes are also taking a more prominent role in alternative cancer treatment. Chris Wark, a man who had stage 3 colon cancer, credits his recovery to a vegan diet.

The point is, these stories are out there, and so is the science to back them up. It makes you wonder why these aren’t considered mainstream treatment suggestions? Perhaps it has something to do with the fact that these treatments cannot be patented?

There are only two approved treatments for cancer — radiation and chemotherapy.

Our Toxic Environment

“How could we have ever believed that it was a good idea to grow our food with poisons?” – Jane Goodall

Billions of pounds of toxic chemicals are sprayed on our food and in the environment every single year. We’re talking about organophosphates, chemicals that were used to kill people in warfare during WW2. After decades of spraying, a number of alarming studies have been published which lead to many of these chemicals being completely banned.

Children today are sicker than they were a generation ago. From childhood cancers to autism, birth defects and asthma, a wide range of childhood diseases and disorders are on the rise. Our assessment of the latest science leaves little room for doubt; pesticides are one key driver of this sobering trend. – October 2012 report by Pesticide Action Network North America (PANNA) (source)(source)

Yet only recently did the World Health Organization admit that glyphosate, the most active ingredient in Monsanto’s Roundup herbicide, can cause cancer. (source) A number of countries around the world have also banned glyphosate. Sri Lanka, for example, decided to completely ban it after their scientists discovered that it was linked to chronic kidney disease. (source)(source) It has also been completely banned in various countries across Europe.

As far as pesticide accumulation in the body goes, a recent study conducted by researchers from RMIT university, published in the journal Environmental Research, found that an organic diet for just one week significantly reduced pesticide exposure in adults by 90 percent.  (source)

Cynthia Curl, an assistant professor in the School of Allied Health Sciences Department of Community and Environmental Health at Boise State University, recently published a pesticide exposure study in the journal Environmental Health Perspectives. Results of her research indicated that among individuals eating similar amounts of vegetables and fruits, the ones who reported eating organic produce had significantly lower OP pesticide exposure than those who normally consume conventionally grown produce.

These studies are important because the pesticides sprayed on our food are also very toxic and have been linked to a number of diseases, like cancer. Why are we consuming chemicals that were used to kill people in warfare? How can we possibly justify such irresponsible behaviour?

And the problem extends further than simply what is being put on our food. Our food itself has been genetically modified by biotech companies, to the point where it bears little resemblance to its natural form, and is equally unrecognizable by our bodies. These companies incorporate genes from one species into a completely unrelated species. (source) This, according to many, is bad science.

The problem is this, geneticists follow the inheritance of genes in what we call a vertical fashion … within a species. What biotechnology allows us to do is to take genes from this organism and move it in what we call horizontally into a totally unrelated species…. What biotechnology allows us to do is to switch genes from one to the other without regard for the biological constraints…. It’s very very bad science. We assume that the principles governing the inheritance of genes vertically applies when you move genes laterally or horizontally. There’s absolutely no reason to make that conclusion. – David Suzuki, geneticist, activist, and environmentalist (source

Furthermore, no studies have been cited by global health authorities which prove the longterm safety of GMOs on our health. This is not good science, and we know for a fact that GMOs are harmful to other animals which we have tested them on. For example, the chronic toxicity study examined the health impacts of eating commercialized genetically modified (GM) maize, alongside Monsanto’s NK603 glyphosate-based herbicide Roundup, on rats.The study found severe liver and kidney damage as well as hormonal disturbances in rats fed with GM maize in conjunction with low levels of Roundup — levels which were below those permitted in most drinking water across Europe. Results also indicated high rates of large tumors and mortality in most treatment groups. (source)

You can read more about that here.

Other studies have found issues with GM foods and pesticides appearing in maternal and fetal blood.

As part of the process, they portrayed the various concerns as merely the ignorant opinions of misinformed individuals – and derided them as not only unscientific, but anti-science. They then set to work to convince the public and government officials, through the dissemination of false information, that there was an overwhelming expert consensus, based on solid evidence, that GMOs were safe. – Jane Goodall (source)

These examples barely even scratch the surface of carcinogens we are exposed to. Cosmetics, flame retardants, everyday household products — these are all a concern. It’s not a mystery why cancer rates are so high, but we never really talk about the issue in this way. Waster fluoridation is another example. Fluoride was recently categorized officially as a neurotoxin.

In point of fact, fluoride causes more human cancer deaths than any other chemical. When you have power you don’t have to tell the truth. That’s a rule that’s been working in this world for generations. There are a great many people who don’t tell the truth when they are in power in administrative positions. This amounts to public murder on a grand scale, it is a public crime. … It is some of the most conclusive bits of scientific and biological evidence that I have come across in my 50 years in the field of cancer research. (source)  – Dr. Dean Burk, Biochemist, Founder of Biotin, and Former Chief Chemist at the National Cancer Institute of Heal

Cancer Charity Fraud

The Brooklyn-based National Children’s Leukemia Foundation has been shut down. This comes years after they raised millions of dollars through professionally run fundraisers. They lured people in, claiming that the funds would be used to conduct cancer research and locate bone marrow donors, while they ran their “Make a Dream Come True” campaign. (source)(source)

This is disturbing information, but it’s not the first time that a major cancer charity has been called into question, not by a long shot. For example, a complaint filed by the Federal Trade Commission describes four connected groups, all with cancer in their name, as “sham charities,” saying they instead “operated as personal fiefdoms characterized by rampant nepotism, flagrant conflicts of interest, and excessive insider compensation.” One of those names was the Cancer Fund of America Inc. These groups stand accused of taking in almost 200 million dollars. (source)

You can read more about that here .

Cancer Prevention

It’s remarkable how much time we spend raising money for cancer treatment without ever speaking about cancer prevention. With out toxic environment, there are a number of things you can do to minimize your risk of developing cancer.

So what can you do? Stop buying household cleaning products with toxic, carcinogenic chemicals. Do your research, ask around. Stop eating foods that are sprayed with pesticides, or at least properly soak and clean your fruits and vegetables for a decent amount of time before consuming them. Indeed, eat more fruits and vegetables to begin with. Exercise more, engage in activities/experiences that make you feel good and bring you joy — these are all simple steps we can take to show our bodies the love they deserve.

Again, I would emphasize diet, as a lot of what we are put into our bodies on a weekly basis isn’t healthy at all.

For example…

“Studies are confirming the health benefits of meat-free eating. Nowadays, plant-based eating is recognized as not only nutritionally sufficient but also as a way to reduce the risk for many chronic illnesses.” – Harvard Medical School (source)

22 Out Of 25 Popular Burger Chains Just Failed Their Antibiotic Use Report

Published

on

In Brief

  • The Facts:

    A recent study was done examining how well top fast food chains actually implemented their antibiotic use policies in their beef. 22 of 25 failed including McDonald's, Sonic, Burger King and In-N-Out.

  • Reflect On:

    Do you still eat fast food? If so, why do you find yourself doing so? What healthier choices can be made instead? If we want to see a healthier world, population and animal kingdom, we have to choose what we support more wisely.

The modern-day food industry seems to pay no attention to health. Thankfully, global consciousness is shifting in several ways including how we live as humans, view our health, our economy, education, politics, and the environment. You could say that humanity is going through one MASSIVE change.

Today, billions of animals in the United States alone are raised, tortured, and slaughtered for human consumption. This reckless production and consumption, in turn, has created enormous environmental and health problems that continue to accelerate. That being said, awareness on this issue (food) in particular, has come along way. We are seeing changes in the food guide, a shift towards plant-based diets, and more corporations catering to new choices people are making around food and health. This is a good thing!

One common trend helping to create change is the continues ‘bad press’ unhealthy players in the food industry are getting.

The latest news to come out regarding food quality within fast food comes from a report recently released by six major consumer and environmental groups. They graded America’s 25 largest burger chains and their use of antibiotics in their beef supply.

22 popular fast food restaurants completely failed, including giants like McDonald’s, Burger King, Sonic and In-N-Out.  The evaluation looked at each chain’s antibiotic use policies and whether these policies were truly implemented in their product. They also examined how transparent the chains were with their antibiotic use.

The Problem With Antibiotic Use

Antibiotics given to farm animals can lead to antibiotic-resistant bacteria, among other things. This is actually one of the top threats to global public health, which is exemplified by the fact that each year, more than 2 million Americans alone suffer from these infections.

In September 1999, Albrecht and Schutte published “Homeopathy Versus Antibiotics in Metaphylaxis of Infectious Diseases: A Clinical Study in Pig Fattening and Its Significance to Consumers” in Alternative Therapies. The study compared outcomes for four randomly assigned groups of pigs that were given placebo, homeopathic treatment, a standard blend of antibiotics and other conventional drugs in a routine low prophylactic dose, or conventional drugs in a high therapeutic dose.

There were 1440 pigs involved in the study, which took place at an intensive livestock farm in Germany. The primary outcome measured was the incidence of respiratory disease, a common problem for pigs on such farms.

The results were astounding.

Homeopathic treatment was far superior to prophylactic doses of antibiotics in preventing respiratory disease. The prophylactic antibiotic treatment made it only 11 percent less likely (than placebo) that the pigs would become sick. But homeopathic remedies made it 40 percent less likely. When the antibiotics were raised to therapeutic levels, meaning a level that is only given when people or an animal was sick, it became 70 percent less likely that the pigs would become diseased.

The significance of this is that homeopathic treatment on animals would already be better than routine antibiotic treatment. When an animal is actually sick, the farmer would then have the choice to increase homeopathic or use a legitimately high-level dose of antibiotics. This, significantly less cost and significantly fewer antibiotics in meat.

The List

The Takeaway

Simple, avoid fast food. There are many out there who seem to believe that people will always consume this food, but we fail to recognize that it’s not just our choice. The “food” these corporations offer is highly addictive to people, and that’s done on purpose.

If we can connect with caring about our health, quality of life and well-being of animals and the planet, these are places you must steer away from. In general, eating meat does not support the health and wellbeing of us nor animals, but this is a choice we each make.

Consider This Before Indulging In Legal Cannabis In Canada

Published

on

In Brief

  • The Facts:

    Cannabis is now legal in Canada for recreational and medicinal use.

  • Reflect On:

    Will the legalization of cannabis change our relationship and habits with cannabis? Should it?

For some Canadians, October 17th is a day they have been anticipating for a long time. For others, it may pass by without much notice. Yet, one thing is for sure. Eventually, virtually all Canadians will be impacted in one way or another by Canada’s decision to legalize cannabis. Parents. Children. Regular Users. Non-users. Teenagers. The Elderly. Those of all ages suffering from illnesses of all kinds.

And not only will this impact the everyday lives of people in Canada, most Canadian institutions will be going through a learning curve and devoting attention to this new phenomenon. The government. Law Enforcement Agencies. Growers and farms. Wholesalers and retailers. Advertisers and marketers. Who in Canada will be able to say they have not been touched by this one way or another, once the intoxicating and healing powers of cannabis become more accessible even than alcohol?

What Will Change

Some changes will happen immediately, some changes will evolve over time. Some people argue that Canada is not yet ready for all the implications of legalizing cannabis at this point, but the prevailing attitude is that things will sort themselves out in an orderly fashion over the next 1-3 years.

Law enforcement: The change in the criminal code means that limited possession of cannabis is no longer a crime, though people who are currently in jail for possession of cannabis are not being automatically let out of jail. Much of law enforcement rhetoric focuses on preventing youth from indulging in cannabis, in a fashion similar to the restrictions on alcohol. More likely, the majority of funds and manpower will be diverted to combating black market enterprises, given that the government now stands to gain $675 million per year in tax revenues from the sale of legal cannabis. Regulations for impaired driving as a result of cannabis consumption look to evolve over time as technologies for measuring impairment like alcohol ‘breathalizers’ improve.

Home Growing: Individuals will be permitted to grow up to four plants for their own use. While the sale of edibles (baked goods, drinks, etc) will not be allowed initially, individuals can make edibles at home for their own use.

Marketing and Retail: The way in which legal cannabis is promoted and sold to the public will likely go through a push-pull transition between advertising regulations and the way wholesalers and retailers will try to get around those regulations to sell their products. The same can probably be said for the business chain as a whole from growth to consumption.

advertisement - learn more

Usage in General: Usage in Canada is bound to increase, simply due to an increase in the availability for those who have not actively sought it out in the past, and the removal of the stigma of its illegality, as well as the social acceptance of the consumption of cannabis which is bound to grow over the next couple of years.

What Will Not Change

There are two things that will not change when cannabis is made legal in Canada on October 17th: cannabis and you.

Cannabis itself is not suddenly safer or better for you than it was before just because it has become legalized. The same decisions you were making on whether or not to indulge in the past still pretty much apply, so ubiquitous was its use despite being illegal. Will regulation make the quality of cannabis you receive better? Not necessarily. It may become more consistent, if less potent, if the quality controls in place are reliable. But remember, black market dealers and sellers had an intrinsic investment in the quality of their product if they were to hope to have regular customers.

By ‘you,’ I am referring to your deepest, truest sense of self, the person you are and who you want to be in the highest vision of yourself. This does not change with any change of regulation in the outer world, and certainly you have to be wary if this change of regulation arbitrarily changes the choices you make and impacts your habits, goals, and dreams.

What To Watch Out For

You may be one who will be inclined to be more open to the personal recreational use of cannabis once it becomes legal. With this comes the possibility of gradually developing a dependence, facilitated by a greater legal and social acceptability. It is important to take notice if recreational use begins to devolve into a catch-all means of escaping from the stress and discomfort of real-life problems, in ways that you get out of the habit of confronting problems and discomfort at their source.

The same can be said about the use of cannabis for medicinal purposes. No doubt, cannabis and CBD oil will be marketed as the healthy sedative for physical ailments and will also be touted as a curative agent for certain types of diseases. While this may be true in some particular cases, you have to be cautious about the claims made by sellers and marketers of the product, whose job is to sell rather than research and diagnose exactly what conditions will benefit from cannabis treatment, and even more particularly what strains of cannabis will work for given conditions.

There is a body of research about the curative effects of cannabis made from an Eastern holistic perspective, which treats each individual case not based on outward symptoms, as Western medicine does, but in terms the particular physiological, emotional and spiritual conditions an individual is in which seen to be at the root of the individual’s ailment. Hence, being wary of marketing practices does not mean avoid cannabis or CBD oil as medicinal treatment for a particular condition, but try to do so in consultation with an unbiased and trusted practitioner/researcher whose motives are healing your particular condition rather than making profits selling cannabis.

The Takeaway

The consumption of cannabis has the potential to be both consciousness-expanding and consciousness-numbing. It does have healing properties but you really have to do your due diligence and use it in a very disciplined way in order to truly gain healing benefits from it rather than getting into the habit of simply escaping from pains and difficulties that are part of a normal life. It is an exciting time for Canadians in that we are now more free to choose something that never should have been illegal to begin with. Let’s make sure this newfound freedom serves us in the best ways as individuals and as a community.

Epigenetic Memories Are Passed Down 14 Successive Generations, Game-Changing Research Reveals

Published

on

In Brief

  • The Facts:

    It's amazing how much information can be passed on to our offspring. Scientist have discovered that our DNA has memories, and these can also be passed down. We are talking about thoughts, feelings, emotions and perceptions.

  • Reflect On:

    Biological changes are shaped by our environment, as well as our thoughts, feelings, emotions and reaction to that environment. Our DNA can be changed with belief, the placebo is a great example. Thoughts feelings and emotions are huge in biology.

This article was written by the Greenmedinfo research group, from Greenmedinfo.com. Posted here with permission.

Until recently, it was believed that our genes dictate our destiny. That we are slated for the diseases that will ultimately beset us based upon the pre-wired indecipherable code written in stone in our genetic material. The burgeoning field of epigenetics, however, is overturning these tenets, and ushering in a school of thought where nurture, not nature, is seen to be the predominant influence when it comes to genetic expression and our freedom from or affliction by chronic disease.

Epigenetics: The Demise of Biological Determinism

Epigenetics, or the study of the physiological mechanisms that silence or activate genes, encompasses processes which alter gene function without changing the sequence of nucleotide base pairs in our DNA. Translated literally to mean “in addition to changes in genetic sequence,” epigenetics includes processes such as methylation, acetylation, phosphorylation, sumolyation, and ubiquitylation which can be transmitted to daughter cells upon cell division (1). Methylation, for example, is the attachment of simple methyl group tags to DNA molecules, which can repress transcription of a gene when it occurs in the region of a gene promoter. This simple methyl group, or a carbon bound to three hydrogen molecules, effectively turns the gene off.

Post-translational modifications of histone proteins is another epigenetic process. Histones help to package and condense the DNA double helix into the cell nucleus in a complex called chromatin, which can be modified by enzymes, acetyl groups, and forms of RNA called small interfering RNAs and microRNAs (1). These chemical modifications of chromatin influence its three-dimensional structure, which in turn governs its accessibility for DNA transcription and dictates whether genes are expressed or not.

We inherit one allele, or variant, of each gene from our mother and the other from our father. If the result of epigenetic processes is imprinting, a phenomenon where one of the two alleles of a gene pair is turned off, this can generate a deleterious health outcome if the expressed allele is defective or increases our susceptibility to infections or toxicants (1). Studies link cancers of nearly all types, neurobehavioral and cognitive dysfunction, respiratory illnessesautoimmune disorders, reproductive anomalies, and cardiovascular disease to epigenetic mechanisms (1). For example, the cardiac antiarrhythmic drug procainamide and the antihypertensive agent hydralazine can cause lupus in some people by causing aberrant patterns of DNA methylation and disrupting signalling pathways (1).

Genes Load the Gun, Environment Pulls the Trigger

Pharmaceuticals, however, are not the only agents that can induce epigenetic disturbances. Whether you were born via vaginal birth or Cesarean section, breastfed or bottle-fed, raised with a pet in the house, or infected with certain childhood illnesses all influence your epigenetic expression. Whether you are sedentary, pray, smoke, mediate, do yoga, have an extensive network of social support or are alienated from your community—all of your lifestyle choices play into your risk for disease operating through mechanisms of epigenetics.

In fact, the Centers for Disease Control (CDC) states that genetics account for only 10% of disease, with the remaining 90% owing to environmental variables (2). An article published in the Public Library of Science One (PLoS One) entitled “Genetic factors are not the major causes of chronic diseases” echoes these claims, citing that chronic disease is only 16.4% genetic, and 84.6% environmental (3). These concepts make sense in light of research on the exposome, the cumulative measure of all the environmental insults an individual incurs during their life course that determines susceptibility to disease (4)

In delineating the totality of exposures to which an individual is subjected over their lifetime, the exposome can be subdivided into three overlapping and intertwined domains. One segment of the exposome called the internal environment is comprised of processes innate to the body which impinge on the cellular milieu. This encompasses hormones and other cellular messengers, oxidative stress, inflammation, lipid peroxidation, bodily morphology, the gut microbiotaaging and biochemical stress (5).

Another portion of the exposome, the specific external environment, consists of exposures including pathogens, radiation, chemical contaminants and pollutants, and medical interventions, as well as dietary, lifestyle, and occupational elements (5). At an even broader sociocultural and ecological level is the segment of the exposome called the general external environment, which may circumscribe factors such as psychological stress, socioeconomic status, geopolitical variables, educational attainment, urban or rural residence, and climate (5).

Transgenerational Inheritance of Epigenetic Change: Endocrine Disruptors Trigger Infertility in Future Generations

Scientists formerly speculated that epigenetic changes disappear with each new generation during gametogenesis, the formation of sperm and ovum, and after fertilization. However, this theory was first challenged by research published in the journal Science which demonstrated that transient exposure of pregnant rats to the insecticide methoxychlor, an estrogenic compound, or the fungicide vinclozolin, an antiandrogenic compound, resulted in increased incidence of male infertility and decreased sperm production and viability in 90% of the males of four subsequent generations that were tracked (1).

Most notably, these reproductive effects were associated with derangements in DNA methylation patterns in the germ line, suggesting that epigenetic changes are passed on to future generations. The authors concluded, “The ability of an environmental factor (for example, endocrine disruptor) to reprogram the germ line and to promote a transgenerational disease state has significant implications for evolutionary biology and disease etiology” (6, p. 1466). This may suggest that the endocrine-disrupting, fragrance-laden personal care products and commercial cleaning supplies to which we are all exposed may trigger fertility problems in multiple future generations.

Transgenerational Inheritance of Traumatic Episodes: Parental Experience Shapes Traits of Offspring

In addition, traumatic experiences may be transmitted to future generations via epigenetics as a way to inform progeny about salient information needed for their survival (7). In one study, researchers wafted the cherry-like chemical acetophenone into the chambers of mice while administering electric shocks, conditioning the mice to fear the scent (7). This reaction was passed onto two successive generations, which shuddered significantly more in the presence of acetophenone despite never having encountered it compared to descendants of mice that had not received this conditioning (7).

The study suggests that certain characteristics of the parental sensory environment experienced before conception can remodel the sensory nervous system and neuroanatomy in subsequently conceived generations (7). Alterations in brain structures that process olfactory stimuli were observed, as well as enhanced representation of the receptor that perceives the odor compared to control mice and their progeny (7). These changes were conveyed by epigenetic mechanisms, as illustrated by evidence that the acetophenone-sensing genes in fearful mice were hypomethylated, which may have enhanced expression of odorant-receptor genes during development leading to acetophenone sensitivity (7).

The Human Experience of Famine and Tragedy Spans Generations

The mouse study, which illustrates how germ cells (egg and sperm) exhibit dynamic plasticity and adaptability in response to environmental signals, is mirrored by human studies. For instance, exposures to certain stressors such as starvation during the gestational period are associated with poor health outcomes for offspring. Women who undergo famine before conception of her offspring have been demonstrated to give birth to children with lower self-reported mental health and quality of life, for example (8).

Studies similarly highlight that, “Maternal famine exposure around the time of conception has been related to prevalence of major affective disorders, antisocial personality disorders, schizophrenia, decreased intracranial volume, and congenital abnormalities of the central nervous system” (8). Gestational exposure to the Dutch Famine of the mid-twentieth century is also associated with lower perceived health (9), as well as enhanced incidence of cardiovascular disease, hypertension, and obesity in offspring (8). Maternal undernourishment during pregnancy leads to neonatal adiposity, which is a predictor of future obesity (10), in the grandchildren (11).

The impact of epigenetics is also exemplified by research on the intergenerational effects of trauma, which illuminates that descendants of people who survived the Holocaust exhibit abnormal stresshormone profiles, and low cortisol production in particular (12). Because of their impaired cortisol response and altered stress reactivity, children of Holocaust survivors are often at enhanced risk for post-traumatic stress disorder (PTSD), anxiety, and depression (13).

Intrauterine exposure to maternal stress in the form of intimate partner violence during pregnancy can also lead to changes in the methylation status of the glucocorticoid receptor (GR) of their adolescent offspring (14). These studies suggest that an individual’s experience of trauma can predispose their descendants to mental illness, behavioral problems, and psychological abnormalities due to “transgenerational epigenetic programming of genes operating in the hypothalamic-pituitary-adrenal axis,” a complex set of interactions among endocrine glands which determine stress response and resilience (14).

Body Cells Pass Genetic Information Directly Into Sperm Cells

Not only that, but studies are illuminating that genetic information can be transferred through the germ line cells of a species in real time. These paradigm-shifting findings overturn conventional logic which postulates that genetic change occurs over the protracted time scale of hundreds of thousands or even millions of years. In a relatively recent study, exosomes were found to be the medium through which information was transferred from somatic cells to gametes.

This experiment entailed xenotransplantation, a process where living cells from one species are grafted into a recipient of another species. Specifically, human melanoma tumor cells genetically engineered to express genes for a fluorescent tracer enzyme called EGFP-encoding plasmid were transplanted into mice. The experimenters found that information-containing molecules containing the EGFP tracer were released into the animals’ blood (15). Exosomes, or “specialized membranous nano-sized vesicles derived from endocytic compartments that are released by many cell types” were found among the EGFP trackable molecules (16, p. 447).

Exosomes, which are synthesized by all plant and animal cells, contain distinct protein repertoires and are created when inward budding occurs from the membrane of multivesicular bodies (MVBs), a type of organelle that serves as a membrane-bound sorting compartment within eukaryotic cells (16). Exosomes contain microRNA (miRNA) and small RNA, types of non-coding RNA involved in regulating gene expression (16). In this study, exosomes delivered RNAs to mature sperm cells (spermatozoa) and remained stored there (15).

The researchers highlight that this kind of RNA can behave as a “transgenerational determinant of inheritable epigenetic variations and that spermatozoal RNA can carry and deliver information that cause phenotypic variations in the progeny” (15). In other words, the RNA carried to sperm cells by exosomes can preside over gene expression in a way that changes the observable traits and disease risk of the offspring as well as its morphology, development, and physiology.

This study was the first to elucidate RNA-mediated transfer of information from somatic to germ cells, which fundamentally overturns what is known as the Weisman barrier, a principle which states that the movement of hereditary information from genes to body cells is unidirectional, and that the information transmitted by egg and sperm to future generations remains independent of somatic cells and parental experience (15).

Further, this may bear implications for cancer risk, as exosomes contain vast amounts of genetic information which can be source of lateral gene transfer (17) and are abundantly liberated from tumor cells (18). This can be reconciled with the fact that exosome-resembling vesicles have been observed in various mammals (15), including humans, in close proximity to sperm in anatomical structures such as the epididymis as well as in seminal fluid (19). These exosomes may thereafter be propagated to future generations with fertilization and augment cancer risk in the offspring (20).

The researchers concluded that sperm cells can act as the final repositories of somatic cell-derived information, which suggests that epigenetic insults to our body cells can be relayed to future generations. This notion is confirmatory of the evolutionary theory of “soft inheritance” proposed by French naturalist Jean-Baptiste Lamarck, whereby characteristics acquired over the life of an organism are transmitted to offspring, a concept which modern genetics previously rejected before the epigenetics arrived on the scene. In this way, the sperm are able to spontaneously assimilate exogenous DNA and RNA molecules, behaving both as vector of their native genome and of extrachromosomal foreign genetic material which is “then delivered to oocytes at fertilization with the ensuing generation of phenotypically modified animals” (15).

Epigenetic Changes Endure Longer Than Ever Predicted

In a recent study, nematode worms were manipulated to harbor a transgene for a fluorescent protein, which made the worms glow under ultraviolet light when the gene was activated (21). When the worms were incubated under the ambient temperature of 20° Celsius (68° Fahrenheit), negligible glowing was observed, indicating low activity of the transgene (21). However, transferring the worms to a warmer climate of 25°C (77° F) stimulated expression of the gene, as the worms glowed brightly (21).

In addition, this temperature-induced alteration in gene expression was found to persist for at least 14 generations, representing the preservation of epigenetic memories of environmental change across an unprecedented number of generations (21). In other words, the worms transmitted memories of past environmental conditions to their descendants, through the vehicle of epigenetic change, as a way to prepare their offspring for prevailing environmental conditions and ensure their survivability.

Future Directions: Where Do We Go From Here?

Taken cumulatively, the aforementioned research challenges traditional Mendelian laws of genetics, which postulate that genetic inheritance occurs exclusively through sexual reproduction and that traits are passed to offspring through the chromosomes contained in germ line cells, and never through somatic (bodily) cells. Effectively, this proves the existence of non-Mendelian transgenerational inheritance, where traits separate from chromosomal genes are transmitted to progeny, resulting in persistent phenotypes that endure across generations (22).

This research imparts new meaning to the principle of seven generation stewardship taught by Native Americans, which mandates that we consider the welfare of seven generations to come in each of our decisions. Not only should we embody this approach in practices of environmental sustainability, but we would be wise to consider how the conditions to which we subject our bodies—the pollution and toxicants which permeate the landscape and pervade our bodies, the nutrient-devoid soil that engenders micronutrient-poor food, the disruptions to our circadian rhythm due to the ubiquity of electronic devices, our divorce from nature and the demise of our tribal affiliations—may translate into ill health effects and diminished quality of life for a previously unfathomed number of subsequent generations.

Hazards of modern agriculture, the industrial revolution, and contemporary living are the “known or suspected drivers behind epigenetic processes…including heavy metals, pesticides, diesel exhaust, tobacco smoke, polycyclic aromatic hydrocarbons, hormones, radioactivity, viruses, bacteria, and basic nutrients” (1, p. A160). Serendipitously, however, many inputs such as exercise, mindfulness, and bioactive components in fruits and vegetables such as sulforaphane in cruciferous vegetables, resveratrol from red grapes, genistein from soy, diallyl sulphide from garlic, curcumin from turmeric, betaine from beets, and green tea catechin can favorably modify epigenetic phenomena “either by directly inhibiting enzymes that catalyze DNA methylation or histone modifications, or by altering the availability of substrates necessary for those enzymatic reactions” (23, p. 8).

This quintessentially underscores that the air we breathe, the food we eat, the thoughts we allow, the toxins to which we are exposed, and the experiences we undergo may persevere in our descendants and remain in our progeny long after we are gone. We must be cognizant of the effects of our actions, as they elicit a ripple effect through the proverbial sands of time.
