Over the last few months I’ve learned of more people who have been strictly following a carnivore diet (exclusively muscle meats) for five or more years. Not at all surprisingly, they are doing very well. Combined with all the evidence I’ve included in my eBooks, and with my own 5+ years on a vitamin A free diet, it’s clear that the theory of vitamin A being an essential nutrient is patently wrong. According to the vitamin A theory these people, and myself, should have gone blind years ago, and had their skin and all their internal organs self-destruct and otherwise disintegrate. Not only has that not happened, it’s just the opposite. These people are thriving and healthier than many of their peers.

As I wrote about in my P4P eBook, the foundational studies used to establish the “it’s a vitamin” concept were pretty much just garbage science. I’m sorry, but poisoning a couple dozen rats to death does not prove the existence of a “vitamin”.

Although many people are now conceding this fact that it’s not a “vitamin” needed by adults, there are still people clinging to the claim that it’s essential for embryo development. I find that claim and position so strange because we know that too much vitamin A will cause horrible birth defects and often times spontaneous abortions. Yet, some people continue to believe that nature is so foolish to establish a critical dicey dependency on a highly toxic molecule to facilitate proper embryo development. This is their last bastion of hope in clinging to the claim that vitamin A is still somehow a “vitamin”.

It gets even more perplexing once you know that the so-called “active form” of vitamin A is 13-cis-retinoic acid (isotretinoin aka Accutane) and all-trans-retinoic acid (tretinoin). These thought to be “active forms” of vitamin A are as toxic to the human fetus as is thalidomide. The FDA has established “black box” warnings that a fetus exposed to “ANY” amounts of isotretinoin is at extreme risk for developing birth defects. Astonishingly, in the face of those facts the established “science” claims that a fetus somehow needs this exact same compound to properly develop. How do we square up these diametrically opposing statements? Of course, we can’t and clearly then there’s something seriously wrong with that claim.

Like with the early rat studies from the 1920s that supposedly conclusively established vitamin A to be a vitamin, we need to analyze the modern day studies that were used to prove the need for retinoic acid in fetal development. Here’s an overview of the premier studies that “unequivocally” established the critical dependency on retinoic acid during embryogenesis.

I find it troubling that so much of medical “science” relies almost exclusively on “studies” such as this. The way I see it, these “studies” are a complete cop-out for genuine, critical and logical thinking. Depressingly, it only takes a few minutes of thinking to see the flaws in this one. It’s just more bad “science” layered upon many shaky assumptions. The parallels here with what happened with the Wolbach and Howe study back in 1925 are also rather remarkable.


From the Department of Pathology, Harvard University Medical School, and the Forsyth Dental Infirmary, Boston. Received for publication, September 4, 1925

The Wolbach and Howe study was conducted for about a 10-week duration. At the end of that duration, most of their test animals were either seriously diseased or had died. The fundamental conclusion from that study was that the animals had suffered their devastating tissue and organ disintegration as a consequence of a vitamin A deficiency.

One of the biggest issues with the Wolbach and Howe study is that although they acknowledged that other contemporary researchers were getting the completely opposite results, Wolbach and Howe simply made up excuses to ignore those inconvenient facts. But, the bigger issue is that they delusionally assumed that they were working with complete information.  Of course, they were not. They failed to appreciate that washing casein in alcohol and heat treating it at high temperatures could have toxified it. And, yes, somehow casein can become remarkably toxic.

Casein is a Carcinogen – Dr. T. Colin Campbell

Topic #1 – Casein is a Carcinogen. Really?

Many people have heard me say, “Casein [the main protein of cow’s milk] is the most relevant chemical carcinogen ever identified.” Guilty, as charged. Many times I’ve said this. For the sake of this discussion, let’s call it an hypothesis, that is, “Casein causes cancer”.

How can the most revered of all nutrients increase the most feared of all diseases? “Heresy”, the mob might shout.

But it’s true. In my laboratory research conducted over a quarter century, funded by taxpayer dollars with findings published in the very best journals, we studied this effect in many ways at a most fundamental, cellular and sub-cellular level as much research as for any other chemical deemed to be a carcinogen.

Campbell was not alone in this research and in his findings. There were similar studies conducted at the University of Illinois at Chicago that replicated these results. Very interestingly, although Campbell was mostly focused on liver cancer, the Chicago researchers found that casein was a very potent carcinogen in quickly initiating and promoting breast cancer in animals.

After Campbell, and the other researchers at the University of Illinois, had made this discovery about the rather incredible toxicity of casein there should have been some rather intensive follow-up research as to exactly why a milk protein could be so toxic. After all, since most mammals start out in life being breastfed, how could milk be such a potent cancer causing agent? On the surface of it, that doesn’t make any sense. However, when you get deeper inside of it and discover the vitamin A molecule contained within it, it becomes much more plausible. I have no doubt the standard casein based lab chow used in Campbell’s et al rat experiments was heat treated. Heat treating it is simply necessary to sterilize it from potential bacterial contaminants.

Except, with this revelation from Campbell et al about casein being a powerful carcinogen, why hasn’t anyone gone back in time and questioned the validity of the 1925 Wolbach and Howe study? After-all, they too used casein in their experiments. Couldn’t their animals have suffered from ‘the most relevant chemical carcinogen ever identified” rather than have suffered from a vitamin deficiency? Additionally, why has no one ever bothered to try to understand why the symptoms of the so-called vitamin A deficiency condition are a perfect match for those of its toxicity symptoms? Isn’t that odd?

I wrote about Dr. T. Colin Campbell’s China study in my P4P eBook. I really liked the China Study, and I still think that it’s a worthwhile read. Two very important conclusions Campbell makes in his book are:

  1. Food is at the root cause of chronic disease (and particularly so for cancer).
  2. The medical sector and medical science is driven by greed and is rife with corruption.

His third, and most important conclusion, is slightly correct, and mostly wrong. He concluded that it’s the milk protein, and therefore by erroneous extrapolation, that most animal sourced proteins are the culprit. However, it’s not the milk protein at all that’s the real culprit. Rather it’s the highly toxic oxidized retinol molecule that’s cased-in the casein that’s to blame. 

Aside: Quite remarkably, this information about the standard lab “rat chow” based diet that included sterilized casein being a potent carcinogen probably invalidates most of other animal based studies that have used this same feed. That’s likely thousands of studies in all aspects of medical research now being highly questionable, at best.

Let’s get back on track here with the more modern day studies that “unequivocally” proved the need for retinoic acid (RA) in embryogenesis. 

Vitamin A and Embryonic Development: An Overview

Vitamin A is an essential micronutrient throughout the life cycle. Its active form, retinoic acid via retinoid receptors, is involved in signal transduction pathways regulating development. Both the lack and excess of vitamin A during embryonic development result in congenital malformations. Approaches to examine the function of vitamin A in embryonic development have included treatment with excess retinoids and the use of retinoid receptor knock-out mice, which have provided important insights into the complexity of the retinoid signaling system.

The entrenched current theory is that RA is a “metabolite” of vitamin A. What’s documented, and then simply blindly repeated hundreds of times over, is that RA is the downstream molecular product needed to “differentiate” our stem cells. However, even under a tiny amount of scrutiny that “theory” is nothing more than an assumption. One of the red flags that should pretty much jump off the page at us is that many of the horrible skeletal defects attributed to RA deficiencies are a perfect match for RA toxicity (or mere exposure to RA). They state:

The overlap of the teratological symptoms of vitamin A deficiency and excess indicates common targets and a critical role for A in the development of many organs. 

Doesn’t that sound familiar?  And then they make this statement.

It is important to keep in mind that the developing embryo is very sensitive to a lack as well as an excess of retinoids.

So, here we go again, having just a touch too much RA or too little RA and you get the same teratological results. Odd huh?

Of course designing an experiment to prove the effects of RA deficiency is rather difficult. They can’t just feed experimental animals a diet deficient in all sources of vitamin A because they “know” that the animals will quickly die, let alone allow them to breed through one or more reproductive cycles. So, what the researchers in this study have done is used genetically modified “knock-out” mice. The gene knock-out changes their DNA so that they will be unable to produce the retinoic acid receptors (RARs) needed to utilize RA.

Retinoic acid is now generally recognized as an important signaling molecule that as a ligand to its nuclear receptors, the RARs alters gene expression at the level of transcription (Gudas et al. 1994, Mangelsdorf et al. 1995, Pfahl and Chytil 1996, Roberts and Sporn 1984).

So, basically, their thinking is to disrupt the RA metabolism pathway so as to block the final critical step of having RA invoking those 500+ random gene expressions.

A recent approach to answering questions about the functions of vitamin A in development has been the use of transgenic mice with changes in retinoid receptor gene structure (Boylan et al. 1995, Chambon 1993, Giguere et al. 1996)

The “disrupted” vitamin A metabolism pathway

Do you see the “disrupted” pathway? Actually, neither do I. 

But, sure enough, with that induced mutation they find exactly what they are looking for. Disrupting the RA metabolism pathway results in the development of horrible and catastrophic skeletal and organ defects. Of course, as predicted, their conclusion is that RA is essential for embryogenesis. 

Many of the abnormalities in these mutant mice resemble those observed in the fetuses from the vitamin A deficient animals reported earlier.

Obviously, there are some huge flaws with these experiments and in their logic. Firstly, what if that cellular process of dealing with RA is not one of “metabolism” but rather one of catabolism and detoxification? Of course, when a cancer patient is given the RA “treatment” their body is not metabolizing it, it is frantically detoxifying it. In the process, the result is the horrific widespread destruction the “medication” causes in almost all patients.

Differentiation syndrome (DS) is most current term; Occurs in Acute promyelocytic leukemia patients undergoing ATRA treatment (Tretinoin, Vesanoid).”

Differentiation Syndrome is a life-threatening complication of induction chemotherapy for patients with acute promyelocytic leukemia (APL). Manifestations of this syndrome include fever, hypoxemia, edema, and, in the past, has been referred to as “cytokine storm”.

Yet, somehow we are supposed to believe that the exact same chemotherapy drug is needed for proper embryogenesis. That should sound rather ludicrous to everyone.

Next, we need to consider what if the gene “expressions” are really manifestations of gene damage? But, most glaringly, what they haven’t proven at all is the condition of RA deficiency. No, there is still vitamin A and RA in the cell. They’ve only blocked its assumed to be one-and-only pathway. However, in no way have they limited the availability of RA to bind with and cause DNA damage. Obviously, even without the RARs, that RA molecule is still free to float around the cytoplasm and bind to the DNA/RNA. Therefore, what they’ve really done in this study is just proven that RA is very toxic to the embryo even when the retinoic acid receptors are not available. That outcome is not at all surprising because we now know that RA fractures and fragments DNA.

We have recently shown that retinoic acid induces micronucleation mainly via chromosome breakage.

Next, what about the long-held assumption that the one-and-only pathway of RA metabolism is via the RARs? Well, it turns out to have been the wrong assumption.

Retinoic acid induces apoptosis by a non-classical mechanism of ERK1/2 activation Alfeu Zanotto-Filho, Martin Cammarota, Daniel P. Gelain, Ramatis B. Oliveira, Andres Delgado-Cañedo, Rodrigo J.S. Dalmolin, Matheus A.B. Pasquali, José Cláudio F. Moreira

Even though RA is involved in differentiation and apoptosis of normal and cancer cells, being sometimes used as adjuvant in chemotherapy, its mechanisms of action involve multiple overlapping pathways that still remain unclear. Recent studies point out that RA exerts rapid and non-genomic effects, which are independent of RAR/RXR-mediated gene transcription.

And they go on to state:

Classically, it has been described that the effects of RA are mediated by ligand-dependent activation of RA receptors (RAR) which act directly as transcription factors modulating gene expression by interacting with RA response elements (RARE) in DNA (Kastner et al., 1995). A number of RA target genes have been identified and many of them are associated with apoptosis and differentiation (Kastner et al., 1995; Pfahl, 2003). On the other hand, recent studies point out that RA modulates signaling pathways in a manner independent on retinoid nuclear receptor-mediated gene transactivation; this has been described as ‘‘non-classical” or ‘‘non-genomic” action of RA.

With that bit of new information, there’s now no legitimate evidence that RA is needed for embryogenesis. And of course there isn’t. How could anyone be so credulous to believe that a molecule as toxic as thalidomide to the developing fetus, and one that’s proven to fracture DNA,  cause cancer, cause 500+ other variations of DNA damage, and to induce rapid apoptosis is somehow needed for embryo development?

Moreover, it’s rather clear that the RARs are one of the last defense mechanisms against RA’s toxicity. 

Then, we need to ask the next obvious question. If the RARs are really part of the detoxification pathway, then what’s the result of that pathway being disrupted?  It’s cancer!

The disruption of RA signaling pathways is thought to underlie the etiology of a number of hematological and non-hematological malignancies, including leukemias, skin cancer, head/neck cancer, lung cancer, breast cancer, ovarian cancer, prostate cancer, renal cell carcinoma, pancreatic cancer, liver cancer, glioblastoma and neuroblastoma.

This finding is similar to the report I referenced in my Breast Cancer eBook where the researchers found that cancer tissues are depleted of the needed alcohol dehydrogenase enzyme. So, basically, it looks like when a cell can no longer defend itself from RA, it can become cancerous. Once again, that should not be a surprise to anyone because of the hallmarks of cancer are damaged DNA and rapid cell mitosis, and that’s exactly what RA does to cells. Hmm? What are the chances that the RARs and RXRs are in actuality the precursors proteins to the RBPs that we now know cells form around retinol and RA and then eject out of itself? 

Anyhow, it’s quite remarkable how the thinking process and conclusions in the Vitamin A and Embryonic Development study “unequivocally” proving that RA is needed for embryogenesis parallels that of the 1925 Wolbach and Howe study. Both teams find exactly what they are looking for and they both ignore huge amounts of evidence by other research and knowledge contradicting their conclusions. Most disturbingly, they just don’t seem to apply common sense to alert them to the fact there’s something drastically wrong with their conclusions. And, like with Wolbach and Howe back in 1925 these researchers are so sure of themselves that they completely ignore the contradictory findings from their contemporaries. I say that because ten years prior to them conducting these elaborate genetic knock-out studies, the HHS was quickly (in just 10-14 days) poisoning young mice to death with the very same molecule they are claiming to be essential for embryogenesis.

Therefore, it’s all quite ridiculous and almost absurd. I mean seriously, with that information how could anyone continue to believe that a proven lethal and teratogenic poison is needed for embryogenesis?

Quite interestingly, both the studies by T. Colin Campbell in the 1990s, and that of Alessandra di Masi’s in 2014 both point to cancer causation, and even specifically to breast cancer causation.  Amazingly, Campbell was able turn on and off cancer progression just by turning up or down on the amount of casein being included in the animal diet. That’s a pretty good indication that cancer is being fueled by the ongoing supply of vitamin A.

Yet, as I wrote about in P4P, very disturbingly, when other researchers do find direct links with vitamin A and the retinoids causing cancer, they conceal it and cover it up. That isn’t science. I view it as criminal negligence, at best. It sure begs the question: how could so much of medical science be so screwed up? Is this deliberate scientific propaganda and manipulation to corral us into disease? Of course, there’s huge amounts of money being made everyday in cutting off the breasts of women. But, no one’s going to make a dime off of breast cancer if we reveal the true root cause of the disease, and can therefore prevent it. T. Colin Campbell was correct; corruption is not only endemic to modern medical science, it appears to be institutionalized in the medical establishment.

I wouldn’t be so snarky about it if this was some harmless mistake. But, it’s not. And, we are not just talking about melanomas and breast cancers either. The USA now has the highest rates of birth defects and spontaneous abortions in the world. We’re talking about nearly a million people in just the USA now living with birth defects. With the current CDC estimates that birth defects are occurring at a rate of 1 in every 33 infants born in the United States this represents an ongoing national disaster. Coincidentally, that 1/33 rate is about on par with the current rates of autism too. 

The human body is many thousands of times more advanced than the current state of medical science. This is clearly evidenced by the fact that the more health interventions and drugs pushed onto our populations the sicker we’ve become. And we’ve become vastly sicker, and on a massive scale too. That alone is conclusive proof that many of the so-called experts have no freaking clue what they are doing. The human body was and is perfect. We just need to learn how to stop chronically poisoning it. In order to do that we need to know when a bogus “vitamin” is in fact simply a poison.
