IfHI Faculty Member Dr. Emily Kane sent me this note:

"Recently there was been discussion on a Naturopathic chat group about the validity of blood type diet, with (IfHI Master) Dr. Virginia Oram being one of your most fervent defenders! Our moderator commented that corn could hardly have been "bad" for all those native Americans. The highly esteemed Pam Taylor offered the following perspective:"

Back in the mid-70's a group of us were doing some comparative studies of skulls from Woodland Native American tribes and skulls from Central America with Dr. Jerry Rose (U. of AR, Dept. of Anthropology), whose specialty was medical anthropology. He pointed out the outlines of arterial imprints in certain groups of the Woodland skulls, which were noticeably larger than those from Central America. He theorized that the adaptive development of the larger blood vessels was a response to the presence of anemia, requiring greater blood flow to supply an adequate amount of oxygen and nutrients to the brain.

The discrepancy was due to diet. The Woodland tribes were known to have cultural "boom and bust" cycles where they would spend some time hunting and gathering while the population expanded and became more robust living off game, fish and berries. Skulls from these groups did not display the enlarged blood vessels. When the tribe reached a certain level of vitality with a large enough population to afford a greater division of labor, they would find a place to settle and and farm, with corn as a staple. The significant increase in corn consumption as a dietary staple eventually resulted in anemia, a lower fertility and birth rate, and a level of irritability that led to less cooperation, more fighting (as evidenced by breakage and healing patterns in the bones), increased mortality and injury, a smaller band of individuals, and eventually resulted in their having to abandon a settled life style and resume hunting and gathering.

He theorized that when native populations in Central America prepared their corn by grinding it with limestone tools the grit that mingled with the corn contained a chemical had an inhibitory effect on corn's assumed inhibition of iron uptake.

Recent rat studies indicate that the periodic iron deficiency anemia of the Woodland population during their settled agricultural periods was more likely due to the amino acid imbalance in the corn (see article notation below) rather than a specific factor inhibiting its uptake. However, the physical evidence over time consistently supported the idea that when the Woodland groups were hunting and gathering, with substantially less corn in their diet, they were measurably healthier.

Studies in cultural anthropology spanning nearly a century note specific disease susceptibilities peculiar to different blood groups. But for sure, whether it's from an anthropological perspective or a naturopathic one, the contributing factors to health and disease, whether focused in an individual or extended to a culture, are multiple and multi-layered.

On days when I have a string of obnoxious patients, I definitely miss the bone lab.

I seem to remember reading that changes in dental and skull molding were also seen in so-called 'Mound Builder Cultures' that appeared to correlate with their evolution to an increasingly corn-based diet. That corn may have had this effect takes nothing away from its sacred role in these societies. It was a key subsistence food which allowed populations to grow and avoid starvation, despite the fact that it may have been a suboptimal source of some key nutrients.

Living on an avoid food is probably better that starving because you can't find any beneficial ones nearby.

Fact is, my research has not met with great acceptance in the naturopathic community. It indicates prudence and occasionally some honest skepticism, although I also think a lot of NDs just can't grok it intellectually. So like the chat moderator, they see it in only its most simplistic manifestations, thus requiring only the simplest objections.

Although you might think that capitalizing on the potential for polymorphisms and biochemical individuality would be a 'no-brainer' in a healing art like naturopathic medicine, the reality is otherwise. Maybe in time things will change, but for now my work lies in that wonderful 'excluded middle' that Charles Forte alluded to; misapprehended by the allopaths and naturopaths alike.

Nonetheless, my old friend, Dr. Pam Snider, who is running the Foundations of Naturopathic Medicine project, an attempt to codify naturopathic tools and techniques, recently asked me to author two entries (co-author with Dr. Joseph Pizzorno on the genomics chapter; lead author on the genomic medicine chapter; and contributing author on nutrition chapter.) I don't know where I'll ever find the time to do this, by Martha has said that she would help out, which almost always makes things better.

Getting ready for a lecture this weekend at Newton-Wellesley Hospital in Massachusetts. They invited me to do two lectures on Saturday, for a total of about three hours running time. I suspect they don't have much awarenes of the GenoType material, so I'll do the first session on blood groups and then perhaps the second on GenoTypes and epigenetics.

Speaking of which, running factor analysis on the GenoTypes yields interesting spacial distinctions. Here is a graph of two principal components of data aligned along the point of maximum variability seen with the so-called 'classic genes'. It helps to imagine the small lines as actually coming out at you, if the graph could be in 3 dimensions.

The Explorer GenoType sticks out under these conditions as a very unique archetype.
