Blood Types & Different Diseases
Are You At Risk?

It is theorized that the original blood type for early primates was type O. DNA retrieved from two Neandertal skeletons showed no A or B antibodies and projected the origin of type O to one million years ago.[1]

"The results however suggest the presence of the human O01 allele already in the common ancestor of Neandertals and modern humans and thereby confirming an emergence of the O01 allele more than 1 million years ago predating the divergence of the modern human and Neandertal populations." [ibid]

DNA from Cro-Magnon and chimpanzie specimens showed type O and A, a mutation that proved adventageous because of some environmental challenges or infestations. Type B is an even later adaptation which is totally absent in the ape world. Most recent is type AB which came about because of interbreeding of A and B types.

If we look at how the original type O humans are faring in today's modern world we can reliably say that they have done very well.

  • Type O has the highest rate of Peptic Ulcers and Angina Pectoris... but
  • Type O has the lowest rate of Pancreatic Cancer, Cardiac Infarctions, and Cardiac Ischemia than the other groups

So nature got it right the first time. The Peptic Ulcers are caused by stomach acid that eats away the mucus coating, mostly in the duodenim, where the stomach empties into the intestines. It's believed that some of this damage is caused by the over production of stomach acids, due to either stress or by the activity of a bacterium that thrives in such an environment, called Heliobacter Pylori.

Bacterial or viral infestation might have contributed to the mutation that produced type A blood. But while type A blood is not associated with Peptic Ulcers, it has been linked to a plethora of diseases, including:

  • Type A blood has been linked to higher cancer of the hypopharynx, larynx, pancreas, stomach, breasts and testicles.
  • Type A blood has been linked to to gall stones, Coronary Heart Disease, elevated serum cholesterol, and an overall reduction of the immune response caused by a resistance to aptosis.

It seems nature took one step forward and half a dozen back, but we may not have the whole story yet.

The emergence of type A ironically coincides with the beginning of a vegan culture, perhaps 20,000 years ago (the date is frequently pushed back) with little dependence on red meat or dairy products.

These were nomadic people who ate a variety of nuts, grains, vegetables and fruits. We have traditionally associated this type of diet with good health, and perhaps it was back then. Type A health has suffered the most from modern dietary habits and has shown less resilience to the present day environment than type O.

Type B represents a mutation that occurred about 10,000 years ago in the central mountains of Asia. This adaptation has fewer diseases associated with it than A; however it falls short of the resilience of O.

  • Type B's Achille's heel is Type 1 Diabetes and, mysteriously, esophageal and gastric cancer in a particular province in China (but nowhere else) [1].

Overall, type B is an improvement over A but not as good as O -- at least in modern times.

Lastly, type AB is the most recent adaptation. Scientists place it about 1000 years ago. As you might expect, the range of diseases falls somewhere between A and B.

Different Diets for Different Types?

Type O

Even with our relatively unhealthy diets, type O individuals seem to be doing something right -- for them. The higher incidence of ulcers and chest pains seems more stress related and that would give some credence to the psychological profiling we mentioned at the beginning of this article.

Type B

The B group is prone to Type 1 diabetes. The current theoretical models for this type of diabetes is the destruction of insulin producing cells in the pancreas caused by some local environmental condition. It has been shown that identical twins, who share the same genome, only share this disease 30% to 50% of the time. Also, migrating populations contract the disease at the same rate as their host country. A virus, Coxsackie of the rubella family, is suspected.

Some researchers believe the autoimmune response is influenced by antibodies against cow's milk proteins.[15] But the evidence has never been conclusive. Giving children 2000 IU of Vitamin D during their first year of life is associated with reduced risk of type 1 diabetes, though the causal relationship is obscure.[16] Children with antibodies to beta cell proteins (i.e. at early stages of an immune reaction to them) but no overt diabetes, and treated with vitamin B3 (niacin), had less than half the diabetes onset incidence in a seven-year time span than did the general population, and an even lower incidence relative to those with antibodies as above, but who received no vitamin B3.[17]

So, although there may be a genetic component linking type B blood with Type 1 Diabetes, there also appears to be a positive response to Vitamin-D and B3 (niacin). Diets rich in these vitamins, plus sunlight exposure, would appear to be beneficial as supplements to a type B diet.

Type A

You will notice that I saved type A for last. With propensities for an assortment of diseases effecting the heart, digestive and endocrine system, this blood type seems most vulnerable to modern diets. Type A people were originally vegans, or at the very least omnivors. The obvious difference is that today's food is often not fresh and is processed with preservatives and other chemicals to prolong its shelf life and increase profitability. These trace amounts of un-natural substances effect all blood types, but type As clearly demonstrate the toxicity of prolonged exposure.

Type AB

This type of blood can suffer from all of the maladies of Type A. Stastically, most research has been conducted on types O and A and it is generally assumed that the detrimental effects are similar to A but not as severe.

What About Rh (Rhesus factor?)

After the ABO blood types were understood and utilized, some fatal reactions to matched blood was still occurring. Karl Landsteiner discovered the second most important factor which he called the Rhesus Factor. The genes for this antibody have been traced all the way back to early primates. People who have this antibody are called Rh+ and make up about 85% of the modern human population. The remaining 15% who lack the antibody are Rh-.

The argument is often made that people who are Rh- are a recent mutation, well after both Cro-Magnon and Neandertals and have suggested that they are alien hybrids, descendants from Atlantis or even a totally different (albeit similar) species from another world. A more scientific theory is offered below:

All modern genetic DNA evidence points to an "out-of-Africa" origin for humanity. Hence, it is our view that Rh+ (Rh-positive) is the original Rh blood allele in humans, since black Africans in Africa who have not mixed either with white populations or with mixed-race persons have ONLY this Rh allele and no evidence of Rh- (Rh-negative).

Since Rh- (Rh-negative) is an allele which is found predominantly among white populations (ca. 40-45% in Europe), it must clearly be a mutation which followed after man's migrations from Africa to Europe.

Moreover, Rh-negative is found much more frequently among A and O blood groups, which are the major blood types in Western Europe, whereas Rh-negative is much rarer among persons with B and AB blood types.

Rh protein plays a significant role as a channel for CO2 gas (carbon dioxide) across cell membranes in the body: "Rh proteins act as gas channels that help speed the transfer of carbon dioxide (CO2) in and out of red blood cells. CO2 can also pass through the cell membrane unaided (above right), but not quickly enough."

Hence, it would seem to be a likely hypothesis to this observer, presented here for the first time, that Rh- (Rh-negative) developed due to a (presumably beneficial) change mandated in our human breathing of the Earth's air in the more northerly European latitudes.

This would make sense since there is in fact a global air-sea flux of CO2 (carbon dioxide) which could correspond to the mutation we see in Rh from Africa (Rh+) to Western Europe (Rh-).

Read the full article HERE.

Literature suggests that people with RH- have higher IQs, lower blood pressure, keen eyesight and hearing, hazel or blue eyes, reddish hair, psychic abilities, cannot be cloned and will reject a fetus that is Rh+. That last bit is used as an argument that Rh- individuals are actually a different species (or hybrid) since no other animal rejects its own offspring except mules, which are a hybrid donkey-horse.

Here's a brief video about Rh-negative people around the world:



A Warning...

For certain their is sound scientific evidence, undisputed, that certain diseases appear more frequently in certain blood types. Beyond that solid observation, the etherial world of special fad diets can waste time and money. YouTube has many videos claiming that certain foods should or should not be consumed by various blood types. Usually, after a brief introduction, the video transforms into a sales tool for a book or CD. You don't need that.

Knowing your blood type gives you a statistical window to how others of your type are dealing with the world today. You can learn by this and avoid foods that are known to contribute to these particular illnesses, paying attention to any family history that may predispose you to getting ill. In general, all blood types are susceptible to the environmental toxins in our food. We were not evolved to eat un-natural chemicals or processed food.

Eat wise.
