No single diet theory can address all aspects of our individuality, and only a fool would claim that soy, red meat, grains, coconut oil or anything else is universally good or universally bad for everyone.
For example, people who are blood type O appear to derive significant benefit from a diet including hormone and antibiotic free meats and poultry. There is a very basic physiologic reason for this: those with type O blood have almost three times the levels of an enzyme in their intestines called ‘intestinal alkaline phosphatase’ (IAP) . This enzyme performs two very important functions in the body. First, IAP splits dietary cholesterol into smaller fragments, allowing for their proper breakdown. Second, IAP enhances the absorption of calcium from the diet. Now you'd think this was cutting-edge, late-breaking news since it is obviously of tremendous interest in these nutrigenomic times. However, the first observations were made over four decades ago.
In addition to these two critical functions IAP is an important influence on the ability of the digestive tract to heal. Thus in most of our type O patients (44% of the population) we see a marked improvement in their IBS, colitis and Crohn’s disease when they increase their protein and cut back on their carbohydrates. 
Blood type B makes considerable amounts of IAP as well, but type A’s make very little. This probably explains why most studies that have looked at heart disease and blood type show a significantly higher rate of problems with blood type A individuals. These folks really should follow a Mediterranean-type diet.
Later studies showed that type A not only secreted almost no alkaline phosphatase in their intestines, but whatever little they did secrete was in and of itself inactivated by the presence of their own A antigen. 
Thus, we have here one of the strongest indications for the long term benefit of a low-fat diet in type A, both with regard to the susceptibility to cardiovascular disease, and (although not mentioned here) their additional susceptibility to cancer. Following the type A eating plan, with its emphasis on a healthy fats, low animal protein and the avoidance of foods high in phenylalanine, is the best method to maximize digestive efficiency in type As, lower their level of intestinal dysfunction, and to influence their susceptibility to cardiovascular disease.
The British biologist Conrad Hal Waddington conceived of genotype (your genetic plan) passing through environment into phenotype (the physical you) as a walk through an 'Epigenetic Landscape'. He conceived a mode of visualizing this process, in which phenotype development is seen as marbles rolling downhill. In the beginning development is plastic, and a cell can become many fates. However, as development proceeds, certain decisions cannot be reversed. This Landscape has hills, valleys, and basins and marbles compete for the grooves on the slope, and eventually coming to rest at the lowest points, which represent the eventual types of tissues they become.
The Epigenetic Landscape. (After Waddington, C. H., 1956, Principles of Embryology)
Waddington was a big thinker. Not only did he visualize development as passing through the peaks, slopes and valleys of the Epigenetic Landscape, he considered this process one of increasing constraint, or as being "canalizedâ€? as he referred to it: That the early choices influence the later options. If we think of the canals of Venice, the analogy works even better; our little gondola floats from one canal into another and then another. Each choice leaves it fewer options than before, and since gondolas need water, so we can't just pick it up and put plunk it into another canal.
Now just for a moment visualize a newly fertilized egg. It already contains all the wisdom and information needed to eventually go on to produce a completely formed human being in its DNA, but over time it must develop various cell lines (called germ layers) that can then go off and further distinguish themselves as arteries, nerves and organs. Its unfolding is stochastic (a process that is non-deterministic in the sense that the current state state does not fully determine its next state.).
"Stochastic" is one of those great words that is more often misunderstood than understood. It is often quoted as being synonymous with random, but the actual Greek seems to imply something closer to "unknowable." It's often used in the arts (very often in music composition.)
In short: We know it's going to happen; we just don't know what is going to happen.
Your journey from genetic imprinting (the genes that were determined at conception) to full phenotype (the physical you) is to a great degree a stochastic process. which is why Waddington's metaphor is so great. Any architect will tell you that a house almost never winds up like that original plans. Environmental variables (cost of materials, availability) alter reality as the construction project moves from one stage to the other. We cannot always predict the eventual outcome, but we can describe and learn about the landscape in which it takes place and that, to a degree allows us to understand things.
Hindsight is always 20/20, because the outcome almost always describes the process.
That journey started long before your conception, since epigenetic gene control is hereditable.
You are in essence, not what you eat, but rather what your parents, grand parents and even great grandparents ate. Unlike defective genes, which are damaged for life, epigenetically controlled genes can be repaired. And, activation and silencing tags that are knocked off can be regained via nutrients, drugs, and enriching experiences. (1)
Conceivably the cancer you may get today may have been caused by your grandmother's exposure to an industrial poison 50 years ago, even though your grandmother's genes were not changed by the exposureâ€¦ or the mercury you're eating today in fish may not harm you directly, but may harm your grandchildren (2)
These inherited traits can continue to influence the onset of diseases like diabetes, obesity, mental illness and heart disease, from generation to generation.
All in all, the next few years should prove most interesting...
The post-genomic era, which is fueled by automation and other technologies, provokes a change in our grossly naive view of genetic determinism (that single genes govern complex traits) to the obvious reality that most human diseases are complex entities. Gene(s), although necessary, contribute only partially to disease, while environmental factors, lifestyles, epigenetics and epistasis significantly influence pathophysiology and, eventually, the expression of transient biomarkers that can be utilized for diagnosis and prognosis. Human osteoarthritis and rheumatoid arthritis are multifactorial, complex diseases. The genetic inheritance of these diseases remains elusive, although they tend to run in families wherein some siblings have a two- to tenfold increased risk of developing the diseases.

Epigenetic alterations have been known to be of importance in cancer for ~2 decades. This has made it possible to decipher epigenetic codes and machinery and has led to the development of a new generation of drugs now in clinical trials. Although less conspicuous, epigenetic alterations have also been progressively shown to be relevant to common diseases such as atherosclerosis and type 2 diabetes. Imprinted genes, with their key roles in controlling feto-placental nutrient supply and demand and their epigenetic lability in response to nutrients, may play an important role in adaptation/evolution. The combination of these various lines of research on epigenetic programming processes has highlighted new possibilities for the prevention and treatment of metabolic syndrome.

This Transfusion: Sword swallowers and sore throats | ABO in Neanderthals| Blood groups and endometriosis | Nutrigenomics and personalized diets | This News This Week
Welcome to The Weekly Transfusion, 1.6 for the week of April 26, 2009.
Sore throats more common in sword swallowers
Sword swallowers run a higher risk of injury when they are distracted or adding embellishments to their performance, but injured performers have a better prognosis than patients who suffer iatrogenic perforation....Major gastrointestinal bleeding sometimes occurs, and occasional chest pains tend to be treated without medical advice. Sword swallowers without healthcare coverage expose themselves to financial as well as physical risk.
I guess it is just that old 'occupational hazard' story, sort of like the study that discovered that woodpeckers don't seem to get headaches.
Genetic characterization of the ABO blood group in Neanderthals
The high polymorphism rate in the human ABO blood group gene seems to be related to susceptibility to different pathogens. It has been estimated that all genetic variation underlying the human ABO alleles appeared along the human lineage, after the divergence from the chimpanzee lineage. A paleogenetic analysis of the ABO blood group gene in Neandertals allows us to directly test for the presence of the ABO alleles in these extinct humans. We have analysed two male Neandertals that were retrieved under controlled conditions at the El Sidron site in Asturias (Spain) and that appeared to be almost free of modern human DNA contamination. We find a human specific diagnostic deletion for blood group O (O01 haplotype) in both Neandertal individuals. These results suggest that the genetic change responsible for the O blood group in humans predates the human and Neandertal divergence. A potential selective event associated with the emergence of the O allele may have therefore occurred after humans separated from their common ancestor with chimpanzees and before the human-Neandertal population divergence.
Certainly one of the major evolutionary advantages of being blood type O was their double-barreled antibodies; this blood type being the only one that reacts to both “A things” and “B things” in the environment. This probably provided an extra layer of protection against any number of epidemic diseases (plague, smallpox) and many endemic ones (flukes and parasites) as well. If this immune “hyper-vigilance” would go on to increase the rates of inflammation and auto-immune disease in their modern descendants, it should also be remembered that these are often diseases of later life, typically past child bearing and rearing age. Thus if it were a late-model alteration, it certainly provided a significant survival advantage. The Founder Effect can be seen in the characteristics and distribution of the genes for Rhesus Negative and O blood type among the early Mesolithic Period during the so called- ‘Happy Paleo’ period, which also shows some correlation with the ancestral haplogroups R1b and I. On the other hand blood type A seems to have conveyed a better chance of surviving the ‘lean’ period of the early Neolithic; a slightly different, perhaps better way to starve. Type A’s more tolerant immune system may have given them the benefit when it came widening the diet and exploring new foods.
ABO and Rh blood groups distribution in patients with endometriosis.
The blood group A was more predominant in women with endometriosis, while blood group O was less predominant. The overall risk of women with endometriosis and A blood group was 2.89 (95%CI, 1.85-4.52). No significant difference was detected in ABO and Rh blood groups in women with endometriosis according to the severity of disease. CONCLUSION: Women with endometriosis have a 2.9-fold increased risk in the A blood group distribution. The role of blood groups in the development of endometriosis remains to be determined.
I verified the observation back in 1988, when we were observing whether increases in opposing blood group antibodies were associated with any reproductive illnesses. We observed that in our small endometriosis group, all women were type A, and all virtually had elevated antibodies to foreign blood types (in their case, blood type B ). It did seem at he time to be an area ripe for future research, but I never got back to it. It is nice to see that others have observed the same tendencies.
The antibodies in the ABO system (isoagglutinins) called anti-A and anti-B are not normally present at birth. The antibodies develop between 3-6 months of age due to the stimulation of the newborn’s immune system by microbes and foods that possess antigens of an opposing blood type. In, for example, type O children, they will begin forming to type A and B red cell antigens as soon as the child starts eating food, because the A and B antigens are actually found in quite a number of plants. So, as soon as the child starts eating plant food, she'll be exposed to those antigens and start making antibodies against them.
Nutrigenomics and Personalized Diet: From Molecule to Intervention and Nutri-ethics
The relationships between food, nutrition science, and health outcomes have been intensively analyzed over the past century. Genomic variation among individuals and populations is a new factor that enriches and challenges our understanding of these complex relationships. Hence, the rapidly emerging intersection of nutritional science and genomics - nutrigenomics - was the focus of a special issue of OMICS: A Journal of Integrative Biology in December 2008 (Part 1).

Two entire issues on personalized nutrition with virtually no mention of any of the bio-markers that really determine individualized dietary functionality: ABO blood groups and secretor status. Maybe these bio-markers are just too low-tech for the average scientist. More likely, the nay-sayers behind the smear campaign I've had to endure over the last ten years have had their desired effects.
No matter, if you read enough history you soon realize that Billy Shakespeare had it right: 'Truth will out.'

I think yesterday’s Grand Rounds at The University of Bridgeport went well. As seems to be the case more and more these days, I had a surfeit of material; much more than I could contain within the two hours allotted --even though I had limited the lecture to only the first part of standard presentation (‘Adjusting People to Genes’).
Dr. Natalie Colicci, my associate over at the D’Adamo Clinic and an alumnus of the Naturopathic Program at UB, thought it was a success and the students (third and fourth year) paid seemingly rapt attention.
It was nice to also see a few of my associates from bygone days including Dr. Eugene Zampieron, Dr. Leigh White and Dr. Ginger Nash-Wolfe.
UB/ND’s Dean, Dr. Guru Sandesh Singh Khalsa and Associate Deans Dr. Elizabeth Pimentel and Dr. Christina Arbogast Woolard have done a wonderful job getting this program up and running. After the lecture Dr. Arbogast gave us a tour of the teaching facility and the University Clinic, which was most impressive. I enjoyed meeting many of the students, administrators and faculty and was pleased to see that a generally positive, professional and pleasant tone permeated the facility. The UB Clinic sees a lot of economically disadvantaged families from the Greater Bridgeport area --many of whom would not normally be able to afford naturopathic health services on any sort of limited budget.
Dr. Arbogast and I talked about my doing some type of special shift in the Clinic, where students who were interested in my research could receive some in-depth training. I’m sure we’ll revisit this sometime in the future, but the idea of teaching in a clinical environment did seem very attractive to me, if indeed a new obligation would appear to be the last thing I need in my life right now.
They asked me to come back in April to finish up the lecture and perhaps delve into some of the epigenetics material as well. I was surprised to hear from the students just how many were already registered for the IFHI 2009 Conference.
How refreshing was this reception as compared to overall apathy and lack of acceptance I’ve received at Bastyr University, my own alma mater. One of undergraduates recently wrote to tell me that during one of the nutrition classes he attended, the instructor proceeded to describe my work with blood groups as ‘unscientific’ and followed that assertion with a description of the ABH Secretor System which my friend described as ‘not having one single correct fact .’
How different is this Bastyr University from the school I knew and loved.
Gerhard Uhlenbruck, everybody’s favorite lectinologist, recently wrote to let me know that he had penned the forward to a new book ‘Micronutrients’ by Uwe Grober (MedPharm) and kindly included a copy. Very nice book which I anticipate will get some thumbing-through over at the D'Adamo Clinic.
A recent review article on ‘Dietary Lectins as Disease Causing Toxicants’ written by Rabia Hamid and Akbar Mascod (Pakistani Journal of Nutrition 8 (3) 293-303, 2009) referenced three of my works in its citation list.
The second sentence in its abstract just about says it all:
It is now well established that many lectins are toxic, inflammatory, resistant to cooking and digestive enzymes and present in much of our food.
Maybe I’ll send a copy over to Andrew Weil.

I'm slated to lecture at the New York Association of Naturopathic Physicians 2008 Conference. I plan to present on 'Verisimilitude and Malignancy.' Mimicry is an early step in the metastatic process and an important factor in the continued cancer-proneness of survivors. This lecture will discuss nutritional interventions physicians can employ to address these susceptibilities to enhance the survivorship of their oncology patients.
