There are four blood types in humans: A, B, AB and O. Type O represents approximately 50% of the population of the world; Type A 40%; Type B around 8% and Type AB less than 2%.
Blood Type O
Blood type O is the thinnest blood and it is responsible for the strongest immune systems (with the exception of some diseases), Individuals with blood type O have strongest stomach acid and live longest of all blood types at present. Genetically, strongest stomach acid was needed to break down the high protein diets(animal protein was one of our original food source) on which our original ancestors thrived.
A negative side effect of strong stomach acid is that it can lead to ulcers when no food is available, or when food is not eaten at regular intervals. Since the ancestors of type O were hunters, descendants carrying this gene tend to be larger, stronger individuals. If you check the blood type of American Indian or Eskimos, who were and in some cases still are, hunters almost all of them are blood type O.
Although Type O has a strong immune system, they are more susceptible to certain diseases such as typhoid, cholera, smallpox, malaria and plague. These diseases are eradicated from first world countries but still exist in third world countries and that's why you don't find many type O individuals over there. Individuals with type O blood lack several blood clotting factors. For this reason, it is suggested that they eat food rich in vitamin K such as spinach and egg yolk. Due to the fact that type O blood is thinnest, it is lot more difficult for plaque to build up in arteries and it reduces the incidence of heart disease in type Os until later years. This is not to say that individuals of type O blood do not get heart disease or cancer, but research indicates the onset of heart disease is later than for all other blood types. Type O individuals are more susceptible to blood disorders such as hemophilia and leukemia. Artheritis or swelling and inflammation of the joints is also an area of concerns for type O individuals. Whether it is their thin blood, that tends to be protective against heart disease until later in life, or the fact that cancer is not as likely to attack this blood group, the statistics of longevity are clearly in favor of the Os.
Blood Type A
The first mutation from type O was A. Individual of type A have the thickest blood of all type. There are two types(A1 and A2). Since A2 is partial mutation of Type O, individuals of this trait carry much of the muscle genetics of Os and can eat a variety of animal protein that A1 can not tolerate. Vast majority of type A individuals are A1. Type A1 must avoid all animal proteins in favor of vegetarian diet. Meat eating type A2 individuals develop heart disease early and while they look strong physically, internally they are ticking time bombs. In United States, due to the meat enriched diet, Type A individuals live shortest life span today. When Type As continue to east meat diet that is inconsistent with their blood enzymes, aggulutination or thickening of their already thick blood takes place and disaster follows. Type A are more susceptible to heart disease and cancer. But there is one exception. In Japan, where people east a staple of fish, rice and green tea - the perfect diet for type A individuals. In fact Japanese life span is longer, as a country, than any other.
When the type As eat animal fat, meat or diary food inconsistent with their blood type - their already thick blood agglutinates or get thicker and stickier. The thick blood requires the heart to pump harder, inevitably causing high blood pressure and enlarged heart muscle, and an increase in heart disease. Also, type A has very low stomach acid by genetc standards. Researchers agree that most cancers are type A related and when they eat meat diet, there are overwhelming number of high blood pressure, heart disease, diabetes and cancer cases. Type A individuals seem to be affected more by stress than any other blood groups. Stress is attributed as a great killer of type As.
Due to all these factors, individuals of type A blood are at higher risk for heart disease and cancer. Type A individuals should follow vegetarian diet with nutritional supplements such as vitamin E, resveratrol(plentiful in red wine and grape juice), which prevents clots from forming and appears to inhibit the oxidation of LDL cholesterol that offers protection from both heart disease and cancer. In addtion, Type As should incorporate green tea, soybeans and tofu in their regular diets. These provide numerous antioxidants and estrogen that research has shown inhibit cancer.
Blood Type B
Type B is the third mutation through man's adaptation after type O and A. Type B blood is not as thin as type O blood, nor it is as thick as type A blood. For the most part type B can eat meat in moderation without great fear of developing heart disease. Although meat is not type B's best food, it is not particularly harmful either. On the other hand, type B individuals have the ability to eat and metabolize dairy products, which both type O and A do not tolerate well at all.
It is believed that improper foods, or the improper metabolism of specific foods, lowers the immune system of type Bs and makes them susceptible to auto-immune diseases. Some of these are life threatening, others just cause untold misery for life.
Another aspect of type B individuals that surprised researchers is the intelligence level. Almost all the type B individuals interviewed were highly intelligent. As a group they were deep thinking individuals who appeared to see the world from a slightly different viewpoint. Although they are obviously bright, they tend to be more introvert and disliked by other blood types. In spite of this, percentage-wise there are more B millionaires than any other blood type.
Type B individuals average second longest lifespan after type Os. This is probably due to the fact that animal protein, which contains all the essential amino acids, is good food for Bs. Additionally, since type Bs can eat a large variety of foods, they are able to acquire all or most of their essential vitamins, minerals and amino acids from food more easily than type As and ABs.
Research indicates that most type Bs are healthy with some unique medical problems. A large proportion of type B individuals tend to suffer from multiple sclerosis, skin disorders such as psoriasis, eczema and fungus. Another problem that keeps popping up for type Bs is foot problem of one kind or another. Numerous subjects had required food surgery, or had problems with their feet that were painful and made everyday walking difficult.
Blood Type AB
Type AB is the only blood type that did not evolve in the same way as other blood types. While the other blood types have been around for thousands of years, Type AB has been in existence for only about 2,000 years. The genetic mistry of this blood type is complex. While the other blood types evolved because of change of environment and food availability, type AB did not.
It is believed that type AB is the result of mixing type A and B. However, since both A and B are dominant genes, genetically speaking, the offspring should have been A or B. Usually mutation come about to gurantee the survival of the species and that might well be the reason for AB mutation. Proponent of this theory would argue that Type AB is less susceptible to all the diseases that strike Os the hardest, and as such, this is nature's way of evolving to ensure the survival of the species. AB represents about 2% of the population worldwide.
On positve side type AB usually has engaging personality, keen mind and are very charismatic. Type AB possessed qualities quite unique as they all influence people in positive way. On average most ABs are likable, outgoing, gregarious and intelligent people at work and play. They are very self-confident and assertive individuals. On the negative side, type ABs are susceptible to both type A & B illnesses. Women of this blood type usually have many menstrual problems such as excessive bleeding, clotting, cramping and irregular menstrual cycles. Additionally, many women also experience migraine. Studies also suggest that type ABs individuals often suffer from harmonal imbalance more than others.
Eating properly for an AB requires guidlines similar to As, but with small amounts of animal protein. Like As, type ABs should acquire their vitamins, minerals and essential amino acids through plants and vegetables. ABs shoul also incorporate green tea, soybeans, and tofu in their diet.
