Blood Type A 

Blood Type A

Your supplements should be as unique as you are! Each blood type has precise nutritional needs - Type A’s supplement focus should be on supercharging the immune system, supplying cancer fighting antioxidants, preventing infections and strengthening the heart. Dr. Peter D’Adamo formulated his blood type specific nutrient packed supplements to meet the individualized needs of each blood type.
  • Polyvite A. Carefully designed by Dr. Peter D'Adamo, this multivitamin provides the Type A individual with the ideal amount of B Vitamins which Type A tends to have a hard time absorbing because of the lack of intrinsic factor, a substance produced by the lining of the stomach that helps absorption of B-12 into the blood.
  • Deflect A. One of our most popular and foundational formulas, Deflect A was formulated to help block damaging lectins and work to repair existing lectin damage.
  • PolyFlora A. This unique formula that's a blend of blood type optimal flora strains designed to provide the right balance of Type A friendly bacteria in your digestive tract.
Dr. Peter D'Adamo offers a full line of products specific to the Blood Type A individual.

The Basics

Blood Type A (Positive) - Secretor

What Makes a 'Type A' an Individual?

What makes Me Me and You You? This is the question that is at the heart of the genetic puzzle. It is also central to our exploration of blood types. The key is genetic heritage - the story line of your life. Even though you are living in the 21st century, you share a common bond with your ancestors. The genetic information that resulted in their particular characteristics has been passed on to you.

People who are A blood type have a different set of characteristics than people who are Type O - they are susceptible to different diseases, they should eat different foods and exercise in a completely different manner. Some believe that personality is influenced by blood type! Dr. D'Adamo, author of the best selling books Eat Right for Your Type andLive Right for Your Type, among others, gives us a blueprint for living in his books. Read on to learn more about the Type A individual.

Type A History 

The Type A emerges into the 21st century with many more complex challenges than their ancestors could have imagined. The key factor in the development of Type A can be traced to the struggle for survival long ago, when there was a rapidly dwindling supply of hunting game stock. Having exhausted the great game herds of Africa, humans pushed farther out from their ancestral home into Europe and Asia. The cultivation of grains and livestock changed everything. For the first time, people were able to forego the hand to mouth lifestyle of the hunter/gatherer and establish stable communities. Over time the adaptations that produced Blood Type A were based on the need to fully utilize nutrients from carbohydrate sources. These biological adaptations can still be observed today in Type A's digestive structure. Low levels of hydrochloric acid in the stomach and high intestinal disaccharide digestive enzyme levels permit the more efficient digestion of carbohydrates. According to Dr. D'Adamo, these are also the very factors, along with low levels of intestinal alkaline phosphatase, that make it difficult for Type As to digest and metabolize animal protein and fat.

What Makes Type A Unique 

Many neurochemical factors in the Type A genetic disposition favor a structured, rhythmic, harmonious life, surrounded by a positive, supportive community. The harried pace and increased sense of isolation experienced by so many in today's society often make these needs difficult to achieve. Type A best exemplifies the powerful interconnections between mind and body. This was vital to the shift away from hunting and procurement to building and growing. However, Type A's more internalized relationship to stress, which served your ancestors well, can be a challenge for the modern Type A. The Blood Type Diet's proactive mix of lifestyle strategies, hormonal equalizers, gentle exercise and specialized dietary guidelines will maximize your overall health; decrease your natural risk factors for cancer, diabetes and cardiovascular disease. The result: high performance, mental clarity, greater vitality and increased longevity.

Type A Diet

"When we discuss 'diet,' we are not talking necessarily about a weight loss plan, that's a side benefit to following this plan. We are actually discussing diet in the more traditional sense, meaning a way to eat," explains, Dr. D'Adamo. Type As flourish on a vegetarian diet - if you are accustomed to eating meat, you will lose weight and have more energy once you eliminate the toxic foods from your diet. Many people find it difficult to move away from the typical meat and potato fare to soy proteins, grains and vegetables. But it is particularly important for sensitive Type As to eat their foods in as natural a state as possible: pure, fresh and organic. "I can't emphasize enough how this critical dietary adjustment can be to the sensitive immune system of Type A. With this diet you can supercharge your immune system and potentially short circuit the development of life threatening diseases."

Handling Stress 

In this busy, ever changing world, it's almost impossible to avoid every day stress. Type As have a naturally high level of the stress hormone cortisol and produce more in response to stressful situations. Cortisol is released in 24-hour patterns, typically in the early morning between six and eight A.M. with a gradual decrease during the day. It helps to cue the body's other cyclical rhythms. Due to the naturally elevated cortisol in type As, additional stress often manifests in several ways; disrupted sleep patterns, daytime brain fog, increased blood viscosity (thickening), and promotes muscle loss and fat gain. In extreme cases in Type As, stress can manifest in more serious ways, causing obsessive-compulsive disorder, insulin resistance and hypothyroidism. To help balance cortisol levels, Dr. D'Adamo recommends that you limit sugar, caffeine and alcohol. Don't skip meals, especially breakfast; eating smaller, more frequent meals will also help to stabilize blood sugar levels. He also points out that the following factors are known to increase cortisol levels and increase mental exhaustion for Type As - be aware and limit your exposure when possible:

    • Crowds of people
    • Loud noise
    • Negative emotions
    • Smoking
    • Strong smells or perfumes
    • Too much sugar and starch
    • Overwork
    • Violent TV and movies
    • Lack of sleep
    • Extreme weather conditions (hot or cold)

Calming Exercise - The Critical Component for Health and Well Being 

Heightened cortisol levels make it harder for Type As to recover from stress. Research has demonstrated that overall cortisol levels can be lowered through a regular program of exercises that provide focus and calming effects. Make these activities a regular - and life saving - part of your lifestyle. Dr. D'Adamo recommends, Hatha Yoga, Tai Chi and Meditation and Deep Breathing Exercises. Meditation has been studied for its effects on stress hormones. It was found that after meditation, serum cortisol levels were significantly reduced. Writes Dr. D'Adamo, "While it's fine for Type As to participate in more intense physical activity when healthy and in good condition, be aware that these forms of exercise do not act as safety valves for stress in your blood type. I have seen Type As excel at weight lifting and aerobic activities, but you have to be careful about not overtraining, as that will actually raise cortisol levels."

The Personality Connection

Blood Type is a marker of individuality - and perhaps of personality as well. In Japan, it has long been believed that Blood Type is an indicator of personality - in fact, you are likely to be asked your blood type in a job interview or while out on a date with a potential mate! In a study conducted by Dr. D'Adamo in 1999, he found some interesting connections between blood type and personality. Type As most often described themselves in ways related to the following characteristics: sensitive to the needs of others, good listeners, detail oriented, analytical, creative and inventive.

Live Right!

In addition to exercise, stress management and eating the right foods, here are some key lifestyle strategies for Type A individuals.

    • Cultivate creativity and expression in your life
    • Establish a consistent daily schedule
    • Go to bed no later than 11:00 PM and sleep for eight hours or more. Don't linger in bed, as soon as you get up, get going!
    • Take at least two breaks of twenty minutes each during the work day. Stretch, take a walk, do deep breathing exercises or meditate.
    • Don't skip meals
    • Eat more protein at the start of the day, less at the end
    • Don't eat when you are anxious
    • Eat smaller, more frequent meals.
    • Engage in thirty to forty five minutes of calming exercise at least three times a week.
    • Plan regular screening for heart disease and cancer prevention.
    • Always chew food thoroughly to enhance digestion. Low stomach acid makes digestion more difficult.
Supplement Solutions for Common Type A Challenges

The Teacher 

Teacher Geno Type

In peak condition, Teachers have a natural exuberance and a calm, steady way of looking at the world. Teachers are first-class adapters. Long ago, Teachers easily incorporated rich and abundant sources of protein in combination with rapid adoption of simple but effective agricultural technologies, and they went on to develop a reasonably flexible worldview. Their biological tolerance is reflected in their personalities. They have a centered, calm manner. In general, Teachers have the souls of an artist and are happy and healthy as long as there are ample avenues for creative expression in their lives. It is no surprise that many of Dr. Peter D’Adamo’s Teacher GenoType patients have a deep involvement with meditation, tai chi, or yoga. Teachers have a special life force or spiritual energy, known as Chi, and a deep relationship with nature. In effect, tolerance becomes a form of coexistence. Teachers tend to age well, and many reach significantly advanced years. 

Teacher Superfoods: Turkey, cod, eggs, peanut butter, walnut, quinoa, beet, avocado, Brussels sprouts, carrot and tofu.

The Teacher

Peter D'Adamo, ND, MIFHI 


Gathering up his wood shavings the Teacher walked over to the waste pile that archeologists call a 'midden' and threw them on it. But something here looked very odd. The top of the pile was covered with tiny white and green sprouts, many still sporting the opened seed case on their newborn leaves. He knew that sometimes this happened on manure piles, but there were no animals kept in the longhouse. Then he remembered those bitter tasting vetch seeds he had tried to eat a few days ago… 

Sometime around 12,000 years ago, communities began to develop in the Middle East that displayed new human technologies that marked yet another great leap forward in human consciousness. Eventually labeled as the Neolithic (“New Stone Age”) era and most famous for the revolution in agricultural technology, in reality it was first and foremost a revolution in the human mindset, initiated by the rise of new beliefs, shared rituals and symbolisms. 

Although most likely an 'Out of Africa' adaptation, Teacher seems to have functioned optimally in a marshy or wetland environment, such as one would encounter in grassy wetlands in inland northern Asia or between the Tigris and Euphrates rivers of Mesopotamia, the Coastal salt marshes associated with the river estuaries of Europe and Africa. In any of these cases, fish, crustaceans and mollusks are traditionally widely available and easily procurable. By the late Mesolithic Period the Teacher worldview was most likely centered upon the scavenging for shoreline creatures and fishing. In this food-rich bioterrain exposure to pestilence would have been a constant fact of life. The exhaustion of these resources or a rising population would have placed severe stress on these societies. 

By 8000-7000 BCE the Neolithic Revolution was widespread in Asia. Asian rice began to come under extensive cultivation in the Yangtze valley of China, having originated around the foothills of the Himalayas. The first agriculturalists were strictly subsistence. Food was grown for personal and family use with very little available for trade. Since these societies were shifting from a diet high in animal protein to one based more on plant protein, it seemed particularly counterintuitive when studies showed that the nutritional standards of Neolithic people were often inferior to that of hunter gatherers and their life expectancy was probably shorter. Many anthropologists think that the Biblical story of the expulsion from the Garden of Eden was actually a metaphor for the pain and suffering from society's conversion from hunter-gathering to the beginnings of food domestication. 

If so, it made the Teacher a first-class adapter and one tough buzzard. 

The quality of life of these early Neolithic peoples would have also taken a major turn for the better as what has since been termed the “Secondary Products Revolution" kicked in and animals began to be seen not just as a supply of meat, but also a source of wool, milk and traction energy to pull plows and carts. Widespread net and spear fishing would also soon reap major new rewards. The going would be tough, but Teacher was just tough enough to stick it out. 

These psychic ties gradually led to the beginnings of social orders and hierarchies. There is evidence for the first time of a control of labor and conflicts characteristic of tribal groups, often headed by charismatic chieftains. The hunter-gatherer way of life was being replaced with the domestication of crops and animals, which enabled people to live more sedentary lives. A settled population permits year-round observation of the growing cycle, and hunter-gatherers are keen observers of the environmental conditions optimal for specific plant products. These would have been what archeologists call Neolithic Founder Crops—the first known domesticated plants in the world. These primary foodstuffs were flax, emmer and einkorn wheat, barley, lentils, peas, chick peas, bitter vetch and broad beans. 

The Teacher carries an impressive wisdom of the body. Long ago, Teacher GenoTypes incorporated rich and abundant sources of protein in combination with rapid adoption of simple but effective agricultural technologies, and went on to develop a reasonably flexible worldview. 

Physical Profile 

Teacher GenoTypes are very, very tough, sinewy folks. Although not often overly tall (6 foot or more) or excessively muscular, they can often do the work of two or three people, since they have a marvelous synchronicity between their kinetic, chemical energy and their electric, nervous energy. 

Generally they are ectomorphs or meso-ectomorphs, possessing a low body fat percentage, small bone size, a high metabolism, and a wiry physique. A characteristic of the Teacher is clearly discernable tendons and ligaments underneath the skin, a sign of flexibility and strength. Teachers tend to be smaller to average height, with torsos and legs of about equal length 

Clear signs of Teacher GenoType include the combinations of blonde hair and brown eyes or black hair and the epicanthic eye fold in Europeans. Incisor shoveling in Africans and Caucasians is another sign of Teacher GenoType. The nose is typically balanced to slightly wide. Interestingly, slight epicanthic folds can often be seen in even many non-Asian Teacher GenoTypes, especially from the more north western parts of Europe. The epicanthic fold may be an evolutionary defense against both the extreme cold as well as the extreme light that occurs in the Eurasian arctic and north. It has also been suggested that the fold provides some protection against dust in areas of desert such as that found in the deserts of northern China and Mongolia as well as parts of Africa. Our common ancestor probably had the epicanthic fold since it has been suggested that the fold provides some protection against dust in areas of desert such that found in parts of Africa. At some point modern Africans and Europeans lost the epicanthic fold, but it was maintained by Asians probably as a defense against both the extreme cold as well as the extreme light that occurs in the Eurasian arctic and north. Interestingly, the marker that often is used by the common mane to identify someone from Asia may well be a relic from Africa. 

Straight hair is another typical (but not always an) attribute of Teacher, and may represent very early adaptations to the cooling of the climate that occurred at about the same time as the disappearance of Neanderthal. 

Lower leg length and upper leg length tend to be relatively balanced in the Teacher GenoType, but the trunk is usually longer than the total leg length. Teacher tends to be small boned, with a smaller frame size, although this may not be true of Africans and Northern Europeans (My ancestors were mostly Dutch and Lithuanian). Teacher somatotypes are typically balanced, with few extreme versions of any somatotype, more typically Teacher is an equal mix of endomorphic, mesomorphic and ectomorphic types. 

A characteristic of Teacher is the ability to clearly discern tendons and ligaments underneath the skin, which is almost never seen with Gatherer GenoType. This seems to result in Teacher having a tremendous amount of lever-like strength which gives these people such a physical capacity for hard work. Abraham Lincoln, a clear sign that Teacher is not a short GenoType (he had a glandular problem called acromegaly), could extend a full-sized wood axe by the end of its handle parallel to the ground for any length of time, to the constant amazement of his friends, who made him demonstrate this feat again and again. 

The Teacher jaw structure is usually 'not round', meaning that the gonial angle can range from squarish to a more balanced shape. Teacher is relatively well balanced when it comes to androgens and estrogens and their lower leg extremity space is usually what would be expected for the gender of the subject. 

Teacher is relatively well balanced when it comes to androgens and estrogens, but asymmetrical with regards to left and right medial planes: Their index and ring finger ratios (D2:D4 ratio) are usually asymmetrical as per left and right sides. Excessively longer ring fingers on both hands in men or index fingers in women indicate that an increased tendency towards developing cancers of the reproductive systems (prostate, ovary, breast, etc.) should be considered. 

In Teacher, the relative size of protruding body parts increases with temperature. This translates into what anthropologists call Allen’s Rule: people and animals in hot climates tend to have longer limbs than those in cold climates. For example, the people of East Africa are tall, slender, with long arms and legs, while the Inuit or Eskimos of Alaska, Canada, and Siberia have short, stocky bodies with short arms and legs. Asian Teachers can be surprisingly long-legged, especially with optimum pre and post-natal nutrition. 

Bergman’s Rule dovetails into this: A smaller body has more surface area per body weight, so it sheds heat more efficiently by sweat. Average body size increases in cold climates, decreases in hot climates; big bodies hold heat better than small ones. This is also quite true of Teacher. 

Most Teachers are PROP 'tasters' or 'super tasters' and usually have an 'A antigen' blood type (blood types A1, A2, A1b, A2B). 

Although encountered almost everywhere (with the noticeable exception of Central and South America) the A gene is a European, and to a certain extent Central Asian gene. Within the confines of Europe, in combination with the gene for blood type B, it splits the continent into a Western aspect (high frequency of A, low frequency of B) and Eastern aspect (high frequency of B, low frequency of A). The people in the “High A Zone” speak Indo-European languages other than Slavonic. 

High concentrations of A are found in the Anatolian highlands of Turkey, and to a slightly lesser degree, the surrounding Fertile Crescent area of the Middle East. These areas are consider by some to be the birthplace of what would become the Neolithic, or agriculture; and though it would be extreme to link a single gene with the enormous effects on the human race that have resulted from the domestication of plants and animals, the physiological effects on the digestive tract that are linked to blood type A indicate that is was most certainly linked with the a series of multi-gene adaptations to grasses and grains. 

These areas were hotbeds of early agricultural development, developing strains of cereals and other grasses such as emmer wheat, einkorn wheat, barley; pulses such as peas, lentils and chickpeas and fibers such as flax. Looking at many of the physiological characteristics of the digestive tract known to associate with type A, it appears that many of the immunological necessities involved in being able to digest and metabolize these early grains (in reality cultivated grasses) were impressed upon the A phenotype, since this the digestive tract this blood group tends to temper the antigenicity of many grains. This has the effect of producing a form of Genetic Drift: Their greater tolerance of often highly antigenic grains would have produced an “immune sparing” effect in blood type A Teacher, with the dividend being invested in more efficient controls of inflammation and better barrier defenses. 

There is a very high incidence of AB blood in sub-continental Indian Teachers, again probably the result of the genetic intermingling of steppe-dwelling Nomad horsemen with the more agrarian, settled local stock. 

Teachers often have a significant number of whorl type fingerprints, a useful indicator of future cancer risks, especially for women. Research has shown that the presence of six or more whorl fingerprint patterns is associated with an increased risk of breast cancer, with a statistical significant no different from having a positive mammogram. That's pretty dramatic! In type A Teachers, a whorl count greater than 6 should be considered a wake-up call for a pro-active cancer prevention program. 

Their Rhesus (Rh) blood group is interesting. They are almost always Rh-positive, and a little further detective work shows that they almost always have the 'ancient' form of the Rh positive blood group (CDE). 

Common wisdom would seem to imply that men wander around much more than women, exploring, burning and pillaging and whatnot; but the genetic reality seems to be quite the opposite. Matter of fact when geneticists compared the mitochondrial data with the Y-chromosome data it seems that women have migrated from one continent to another about eight times more frequently than men. This may be the result of women leaving their own families and joining their husbands, or by polygyny, men fathering children by multiple female partners. 

Geneticists typically can’t do very much with single mutations, and lucky for them they don’t often have to since nature often works in bigger chunks of markers called haplotypes. The word haplotype is a combination of the phrase haploid genotype, which in layman’s terms means “double genetic stuff”. It’ double because, remember, you have two complete sets of genes; one from mom and the other from dad. When they did their little disco dance at the moment of your creation, the parts fused together, deciding then and there which of the rivals for your attention (alleles) would go on to be top dog. 

Haplotypes are simply a chunk of alleles at different places along the same chromosome that are inherited as a unit, sort of like if you went to a clothing store, bought a blue sweater, and wound up being convinced by a very good salesperson that the sweater would look great with this pair of plaid pants. 

The Rh blood type system was complex. Now I will explain why. We all inherit a set of three Rhesus (Rh) genes from each parent as part of a haplotype. You may have heard of them or even had them told to you when you got blood typed at a donation center: They’re called the c, d, e, C, D and E genes and when the smoke clears after conception, they’re a haplotype. 

As with all genetic-speak, upper case means a dominant gene and lower case means a recessive one, but here is where it gets interesting. Unlike eye color, where we could conceive of a single allele bossing the other around, like Ali versus Frazier in the “Thrilla in Manila”, with Rh blood groups it’s the relationship of two gene chunks, each of three alleles; more like the Jets versus the Sharks in West Side Story. You get a chunk of three alleles from mom and they rumble with the three Rh alleles from dad, however instead of calling them a gang, or ‘youth group’ we call them haplotypes. 

To finish the story of the Rh groups, if moms gave you the Rh haplotype cDe and dad gave you the cde haplotype, you’d be Rh positive. Actually any capital letter will make you positive, but a capital D will make you especially positive. Which is why some folks describe Rh earlier as 'big D' and 'little D.' Those GenoType Explorer Basques? Why, 50% of them got nothing but lower case letters (cde/cde). 

A common problem for male African Teachers is 'favism' (a type of anemia) though it is of the less severe form that seen with Mediterranean folks. Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme found on red blood cells that is critical to maintaining proper levels of the anti-oxidant glutathione in its bioactive 'reduced' form. Reduced glutathione acts as a scavenger for dangerous oxidative metabolites in the cell. Many drugs and a few foods can induce this damage to the red blood cells, which often is severe enough to cause anemia. Components in fava beans (vicine and convicine) which can induce severe hemolytic (destructive) anemia in people with the G6PD deficiency. Deficiency of G6PD is one of the most common enzyme defects in humans, affecting at least 300 million people worldwide. 

Teachers often have polymorphisms of the cytochrome p450 detoxification system. The first thing you need to know is that the name cytochrome P450 has no relevancy whatsoever. It was coined in the early 1960's to describe an unknown pigment in cells which when bound with carbon monoxide, absorbed light at the 450nm wavelength and the name has stuck ever since. The P450 system is a giant superfamily of enzymes that now number well over 400 genes, with 60 in us humans alone. With all those genes, there needed to be some sort of order developed, so in 1987 a system was developed whereby the symbol CYP followed by numbers and letters detailing the gene and its individual qualities. 

In general the Teacher worldview is an effective and accurate predictive response to most aspects of the modern environment. However, many of the more nefarious aspects of modern life, in particular the use of drugs such as nicotine, caffeine and recreational pharmaceuticals will pose an even more significant threat to Teacher than perhaps might otherwise be appreciated. Teachers tend to have rather low levels of enzymes coded by the CYP2E1 gene which metabolize many chemicals, including drugs and many low-molecular-weight carcinogens. This enzyme is also of interest because it is stimulated by alcohol and may play a role in liver injury induced by chemicals such as chloroform, vinyl chloride and carbon tetrachloride. 

The enzyme is primarily found in the liver, and the level of enzyme varies markedly between individuals. Teachers may well be drawn to alcoholic beverages as a way of increasing this enzyme, as alcoholics have twice as much CYP2E1 activity as compared to nonalcoholics. This may be especially true of Teachers who are also non-secretors. 

Ancestry and Variation 

A fairly ubiquitous GenoType, the Teacher is found in just about every racial and ethnic group, although it is especially common in East and South Asians and Western Europeans, which implies that it is probably not much of a marker for the modern day racial and ethnic categories. Teacher is also found equally in both men and women. The ancestral DNA haplogroups for Teacher in general are those types that are descended from macrohaplogroups associated with the 'Out of Africa' spread of Neolithic technologies. 

Teacher is:
  • Commonly Seen: North Eastern, South Eastern Asians, New World Mixes
  • Frequently Seen: North Western, Western Europeans
  • Often Seen: South Eastern African

Y-Chromosome DNA Analysis 

Although not a predominantly African GenoType, some aspects of Teacher genodynamics may be seen in some of the Bantu descendants who carry the marker for Haplogroup E3a. Many Teacher genotypes are descended from the macrohaplogroup F, although most no longer carry F, but rather one of its myriad descendants, especially the M9 mutation which marks Haplogroup K and its descendants, many of which form the mass of Teacher GenoType: haplogroup O in East Asians and R1b in West Europeans. Haplogroup O and its variants (O1, O2, O3) appear to be adaptations to rice farming, whereas R1b is considered a marker of Cro-Magnon migration into Europe in the time before the last glacier. 

Haplogroup O3 is a subset of haplogroup O arising about 10,000 years ago from an ancestral male who lived in China. This haplogroup appears in over 50% of all modern Chinese men, and is not found outside East Asia. The widespread success of haplogroup O3 is conjectured to be closely associated with the sudden agricultural boom associated with rice farming. Individuals who are haplogroup O3 are descended from China’s first rice farmers. 

DNA Mitochondrial Chromosome Analysis 

Many non-European Teachers are descended from the rather rare R haplogroup R, Haplogroup R is a direct ancestor to the very large B haplogroup, arising in Asia some 50,000 years before present and is found throughout modern Asia and the New World. 

Haplogroup R is believed to have occurred somewhere in North West Asia between 30,000 and 35,000 years ago. The most important subgroup of haplogroup R is R1, which is is very common throughout Europe and western Eurasia. Its distribution is believed to be associated with the re-settlement of Eurasia following the last glacial maximum. The main subgroups of R1 are R1a and R1b, which pretty much break down into an East and West description of things. 

The other lineage traceable to R, and hence back to N, is Haplogroup JT and its descendant T. Although apparently originating in Eastern Europe via the Middle East, haplogroup T has migrated westward, to the point that it is now found in about 10% of all Western Europeans. Like YDNA haplogroup O, T is a Neolithic, agriculturalist marker shared by many Warrior GenoTypes as well. 

SNPS that may be of special interest to Mu include the genes that regulate homocysteine metabolism and the production of methionine. These include:
  • MTHFR (5,10-methylenetetrahydrofolate reductase): Polymorphisms have a role in susceptibility to certain cancers and cardiovascular problems (through its role in regulating homocysteine)
  • MTR (5-methyltetrahydrofolate-homocysteine methyltransferases): MTR encodes an enzyme which catalyzes the final step in methionine biosynthesis, a critical aspect of DNA methylation.
  • MS-MTRR (5-methyltetrahydrofolate-homocysteine methyltransferase reductase) This gene produces enzymes which are involved in the activity of the enzyme methionine synthase, which catalyzes the production of the amino acid methionine. Methionine is an essential amino acid required for protein synthesis and for DNA fidelity.
Metabolic Profile 

Teacher GenoTypes are very, very tough, sinewy folks. Although not often tall or excessively muscular, they can often do the work of two or three people, since they have a marvelous synchronicity between their kinetic, chemical energy and their electric, nervous energy. Usually when one fatigues, the other takes over, and indeed a useful way for Teacher to relax is to simply alternate between these energy systems. 

Because of the inherent tolerance of the Teacher immune system, their digestive tract is often host to a wide and sometimes bizarre arrangement of microbial life. Normally this is not a problem, and may well even be a slight benefit; but the Teacher should always have a 'low overgrowth' component to their food selection strategies. In general most simple sugars and carbohydrates should be minimized, as their breakdown products will in short time produce an explosive microbial overgrowth in the lower intestines. Extreme forms of microbial social engineering—such as antibiotics—almost always cause major disruption of the Teacher digestive tract unless modulated with extra short chain fatty acids, soluble fiber and probiotics. A sure sign of the Teacher is a blood type A individual with whorl type fingerprints and high breath hydrogen test readings. 

In his book Food Is Your Best Medicine Bieler describes a version of the Teacher GenoType as a 'Thyroid Type' characterized by a slim build and an inability to gain weight, restlessness, rapid movements, fine features, and an overactive nervous system. Of the traditional classifications systems, the Chinese yin/yang classification of 'Yin-Water' is closest to the Teacher type: Blunt, passionate, confident, fearless, excellent stamina, ambitious, robust, and authoritarian. Yin-Water types also dislike most cold things and are quite averse to bathing in cold water. 

Stress Profile 

Their tolerance of the physical world, and also to life in general, gives Teachers great insight into the nature of existence—which to them is simply the sum total of all matter in motion—and provides the Teacher GenoType an insightful, supernatural bent. However the Teacher is not antiscientific; rather, that it identified and aligned with natural processes and cosmology long before there was a science and probably will continue to do so long after it as well. 

The Teacher worldview is an effective and accurate predictive response to most aspects of the modern environment. Their biological tolerance is often reflected in their personalities. They have a centered, calm manner. However, many of the more nefarious aspects of modern life, in particular the use of drugs such as nicotine, caffeine and recreational pharmaceuticals will pose an even more significant threat to the Teacher than perhaps might otherwise be appreciated. 

In general, Teachers have the souls of an artist and are happy and healthy as long as there are ample avenues for creative expression in their lives. They are great at meta-analysis, the ability to evaluate numerous types of data and synthesize its essence or gestalt. 

Aging Profile 

Because it is such a tolerant GenoType Teachers are not all that inflammatory-prone and in general seem to be less allergic. Teachers tend to age well, and often reach significantly advanced years. But this doesn't happen automatically. The key for Teachers is to seek balance in everything—whether it be diet, work schedules, sleep-wake cycles, or methods of exercise. Despite often reaching advanced age, a significant number of Teachers can experience major health problems in early middle age, such as cancers and circulatory problems. 

Allowing the Teacher to reach a healthy old age is as simple as preventing methyl groups from getting knocked off their DNA molecules from stress, toxins and sickness, and replacing them with new methyl groups if they do. This process, called methylation, is critical to the proper health and aging of the Teacher GenoType. A lack of proper methylation turns Teacher DNA into the genetic version of that joke circulating around the office cubicles; a photostat of a photostat repeated so many times that the graphics and text are barely readable. 

In Ayurveda a case could be made for some of the more overt aspects of Teacher GenoType fitting the constitutional type called Vata. Vata types are highly imaginative and quick to learn and grasp new knowledge. However they tend to respond to stress with fear, worry, and anxiety, especially when out of balance. Physically Vata types are slender, chests are flat and their veins and muscle tendons are visible. 

Immune Profile 

The thymus and bone marrow loom large in the proper balance of the Teacher GenoType. Once dismissed as non-essential organ, it is now known to play a important role in the early development of the immune system, being the primary site of T cell maturation. By puberty, our thymus atrophies, gradually shrinking in size and function. For Teacher, hydrotherapy, particularly the bathing in cold spring water, has a provocative effect upon the thymus and immune system, probably due to receptors in the skin which are activated by sudden changes in temperature. Dry brushing and lymph drainage are all useful in stimulating the thymus and bone marrow through the skin. By increasing circulation in the body, hydrotherapy increases circulation of white blood cells, which stimulates the immune system. 

Having an altruistic worldview may be an admirable quality, especially when it comes to migration and having to adapt to new flora and fauna, but not when it is expressed at the expense of one's own well-being. The Teacher who has exhausted his or her immune system with overwork, sleep deprivation, stress or poor diets, will have trouble fending off chronic infections. They become easy prey for the latest bacteria making the rounds in their offices or schools. Teacher children suffer from chronic ear and respiratory infections, and they often appear sickly. 

In general, the Teacher's immune system is rather slow to activate, particularly against bacteria and parasites. This has its benefits, since the Immune system does not spin its wheels hunting down and destroying things that it could just as well have gotten along with, and this trait was critical to allowing the early Teachers to migrate throughout the world. However, the tolerant Teacher immune system can easily over-identify with the external world, lowering its defenses against microbes, harmful foods and aberrant cells. Poor Immune surveillance means vulnerability to infections, as well as a higher than average risk for many common cancers. 

The tolerant Teacher immune system can easily over-identify with the external world, lowering its defenses against microbes, harmful foods and aberrant cells. Poor Immune surveillance means vulnerability to infections, as well as a higher than average risk for many common cancers. This often occurs in Teachers because tumor cells often turn-off genes that are supposed to keep them in check. These 'jail-keeper' genes are called tumor-suppressor genes and they are supposed to prevent cancer genes from activating. Often in Teachers, the first thing cancer genes do is figure out a way to turn off the suppressor genes. At that point the inmates are running the prison. Fortunately with the Teacher GenoType diet, you can put those suppressor genes back to work for you. 

Like the Hunter, the Teacher metabolism can turn catabolic. This is often the result of unbalanced ubiquitinylation, a type of cellular elimination system. This is accomplished inside the cell by a small molecule called ubiquitin, so named because it is ubiquitous (found everywhere) in the cell. Ubiquitin is now known to be involved in several other cellular processes as well, including quality control protein synthesis, membrane signaling, control of the cell reproductive cycle, X chromosome inactivation in men and the maintenance of chromosome structure. Unbalanced ubiquitinylation can cause problems with the Teacher's cell signaling mechanisms (surface receptors) and influence tumor suppressor activity. As with Hunter, this often interferes with proper removal of mutant and damaged proteins and growth modulators. While many people today often feel the need for colonic irrigation to 'clean out' their system, in Teachers it is their cells, not their colons, which need the colonic. 

Lack of self-identification, or perhaps over identification of one self in the external world, poses difficulties for GenoTypes with altruistic worldviews. Altruism as an unselfish concern for the welfare of others is fine enough, but to consider others as more important than oneself is degrading and demeaning to the self. Extending one's own worldview to humans, many of whom already subscribe to a code of conduct that rewards altruistic behavior is certainly praiseworthy. Lowering one's threshold of suspicion toward microbes, harmful foods and aberrant cells is another thing altogether. That is a problem for the modern day worldview of the Teacher GenoType: they can blend into the world so good they sometimes lose sight of themselves. 

Adult Teacher GenoTypes will often report that a sibling or parent has developed cancer, and there is often quite a bit of cancer in the family lineage. In westernized countries, Teacher is especially prone to cardiovascular disease as well. 

Functional Aesthetic 

As it says in the Bible, 'The sins of the father will be visited on the sons.' 

However, this is only partially true. 

The improvements of the father (or more likely, the mother) will also be visited upon the offspring as well. Teacher derives great benefit from many of the plant based anti-oxidants that are of the so-called flavonoid class and not surprisingly a lot of these have made it into the traditional diet in areas with high concentrations of Teachers. These include many natural compounds which are though to exert epigenetic effects due to structural changes that they make to the three dimensional structure of DNA. This is done by changing the function histones, proteins that act as spools for DNA to wrap itself around. Although Teacher may want to do yoga stretching and Chi Gong breathing to achieve greater relaxation, their DNA, if anything, would like very much to stay coiled up and tightly wrapped. Compressed DNA tends to be quiet DNA and Teacher likes quiet DNA. 

With the right diet and lifestyle changes, the results of following the GT3 Teacher diet and lifestyle recommendations are nothing short of miraculous. Once the Teacher embarks on a program of dietary and lifestyle changes, the results are immediate. Their recovery powers are quite remarkable. 

Teacher Supplementation 

Teacher Activator 

Teacher Activator is designed to provide nutritional support for the optimization of DNA methylation; the enhancement of proper microbial balance in the digestive tract; and the encouragement of proper cell respiration aerobic glycolysis versus anerobic glycolysis, in keeping with the 'Warburg Hypothesis.' 

Teacher Activator Supplement Strategy:
  • Betaine: Betaine is well known as a gastric acidifier. This help minimize chances for bacterial overgrowth in the upper GI tract, principally the stomach and duodenum. Betaine is also an excellent donor of methyl groups, which are needed to maintain proper DNA fidelity.

  • Biotin: In addition to provide a balancing effect on the digestive microflora, discouraging excess fungal growth, biotin (a B vitamin) has dietary histone deactylase inhibiting effects, encourage proper DNA winding and unwinding.

  • Coriolus versicolor and Thiamine: Coriolus versicolor mushroom is high in natural sterols including beta-sitosterol and ergosterol. These help optimize proper immune function. In combination with the B vitamin Thiamine, Coriolus helps channel cellular respiration towards the oxygen dependent pathways (aerobic glycolysis) and away from the low oxygen pathways (anerobic glycolysis)

  • Saccharomyces cerevisiae, lactobacillus plantaru, Lactobacillus bulgaricus: These probiotics and healthy yeast strains enhance proper microbial balance in the digestive tract and help remove metabolic toxins and endproducts of excess bacterial overgrowth.

Teacher Catalyst 

Teacher Catalyst is designed to provide maximum cell-integrity stabilization and to assist in the optimization of gut by enhancing cell repair and intracellular energy production. 

Teacher Catalyst Strategy: 

  • Vitamin D: This important vitamin (actually a hormone) has important gene stabilizing effects. Vitamin D metabolites influence the expression of various genes involved in calcium homeostasis, cell differentiation, and regulation of the immune system.

  • Selenium: This micromineral is important for its effect in enhancing gene methylation and its ability to remove genotoxins though it interactions with the antioxidant glutathione. An adequate selenium status has for long been considered to prevent the development of various forms of cancer.

  • Quercetin: A significant anti-mutagen, quercetin is a bioflavanoid anti-oxidant found in most plants. In addition to its cell-stabilizing effects, quercetin also enhances the cell's ability to process glucose and has mild anti-allergic properties.

  • Panax Ginseng: American ginseng (Panax quinquefolius L., Araliaceae) possesses anti-cancer potential and is one of the most commonly used herbal medicines in the United States. Waxy components in American gensing, called saponins, have been shown to promote gene stability.

  • ECGC Green Tea: The ends of human chromosomes are protected from the degradation associated with cell division by long end sections called telomeres. In normal cells telomeres lose up to 300 base pairs of DNA per cell division that ultimately leads to senescence; however, most cancer cells bypass this lifespan restriction through the expression of an enzyme that helps repair the telomeres (telomerase). Unfortunately many cancer cells express excess telomerase as part of their quest for immortality. ECGC Green Tea helps regulate telomerase activity, in addition to helping remethylate the sections of genes that demethylate with aging.

Teacher Synergist 

Teacher Synergist is designed to provide 1,000 mg of Flax Seed Oil providing a GenoCorrect balance of Omega-3, Omega-6, Omega-9, and Flaxseed Lignans. 

Teacher Synergist Supplement Strategy: 

  • Flaxseed oil Omega-3 fatty acids have been shown to reduce inflammation and help prevent certain chronic diseases such as heart disease and arthritis. These essential fatty acids appear to be particularly important for cognitive and behavioral function as well as normal growth and development. Lignans, such as those found in flaxseed oil, appear to help modulate excess growth factors levels later in life (which may help enhance longevity) and encourage apotosis (programmed cell death) in cells damaged by aging or mutation.
