           THE BLOODGROUP DIET THEORY


Wikipedia:

"The blood type diet is a diet advocated by Peter D'Adamo and outlined in his book Eat Right 4 Your Type. Its basic premise is that blood type is the most important factor in determining a healthy diet.

The cornerstone of his theory is D’Adamo’s premise that lectins in foods react differently with each ABO blood type. Throughout his books he cites the works of various biochemists and glycobiologists as support for this theory. In his book, Eat Right 4 Your Type, “Lectins: The Diet Connection”, and in following chapters, lectins which interact with the different ABO type antigens are described as incompatible and harmful, ergo the selection of different foods for A, B, and O types to minimize reactions with these lectins.

D'Adamo bases his ideas on the ABO classification of Karl Landsteiner and Jan Janský, and some of the many other tissue surface antigens and classification systems, in particular the Lewis antigen system for ABH secretor status. D'Adamo has gathered many references pertaining to blood groups on his website.[1]

The evolutionary theory of blood groups, which is also used by D'Adamo, stems from work by William C. Boyd, an immunochemist and blood type anthropologist who made a worldwide survey of the distribution of blood groups. In his book Genetics and the races of man: An introduction to modern physical anthropology, published in 1950, Boyd describes how by genetic analysis of blood groups, human races are populations that differ according to their alleles. On this basis, Boyd divided the world population into 13 geographically distinct races with different blood group gene profiles.

D'Adamo groups those thirteen races together by ABO blood group, each type within this group having unique dietary recommendations:

    * Blood group O is believed by D'Adamo to be the hunter, the earliest human blood group. The diet recommends that these supposedly muscular, active people eat a meat-rich diet along the lines of the Paleolithic diet.

    * Blood group A is called the cultivator by D'Adamo, who believes it to be a more recently evolved blood type, dating back from the dawn of agriculture. The diet recommends that individuals of blood group A eat a diet emphasizing vegetables and free of red meat, a more vegetarian food intake.

    * Blood group B is, according to D'Adamo, the nomad, associated with a strong immune system and a flexible digestive system. The blood type diet claims that people of blood type B are the only ones who can thrive on dairy products.

    * Blood group AB, per D'Adamo, the enigma, the most recently evolved type. In terms of dietary needs, his blood type diet treats this group as an intermediate between blood types A and B."

Humans are considered to be primarily vegetarian/fruitivorous more precisely. We became carnivirous as a result of a secondary adaptation process. Proofs of this are the long gut (carnivores have a much shorter one), colour vision (again, this is typical of fruitivores) and the presence of starch-degrading enzymes in our saliva (carnivores can't do that). So, if 0 is the primal blood type, then it must have evolved before having to adapt to a hunter's lifestyle. That's why I find the theory to be flawed. Moreover, it's been made pretty clear by nutritionists that everyone, regardless of blood type, can live perfectly normally on a vegetarian diet. There might be certain affinities though, but associating the 0 type with meat eaters is dubious.

               --Blood Types and Health--

Our blood type is significant for our health because of three classes of chemicals—antigens, antibodies, and lectins. An antigen is any chemical that generates an antibody by the immune system in response to it. An antibody is a substance, an "immunoglobulin," made by cells of the immune system specifically to identify foreign material in the body of the host and to adhere to the foreign material. A lectin is any compound, usually a protein, found in nature, which can interact with surface antigens found on the body’s cells causing them to agglutinate or clump together.

Antigens and antibodies

As far as antigens are concerned, we each have a variety of our own that enable the immune system to decide whether a substance in the body is foreign or not. They are located on the cells of the body. Every form of life from the simplest virus to human beings has a unique set of antigens. In the human body one of the most powerful of these is the one that determines blood type. When the immune system senses a suspicious invader it looks first to the blood type antigen to decide whether or not it is friendly. Our blood type is named for the blood type antigen found on the red blood cells. Thus, type A has A antigen, type B has B antigen, type AB has both A and B antigens, and type O has no antigens.

When a blood-type antigen senses that a foreign antigen has entered the system, it alerts the immune system to create antibodies to that antigen. Immune system cells manufacture these antibodies, which attach themselves to the foreign antigen for destruction. Over time we develop an increasing number of different antibodies. When an antibody meets the antigen of a bacteria or virus or parasite it causes the microorganism to become sticky or agglutinate. The organisms clump up and can be disposed of more easily.

    When a blood-type antigen senses that a foreign antigen has entered the system, it alerts the immune system to create antibodies to that antigen. Immune system cells manufacture these antibodies, which attach themselves to the foreign antigen for destruction.

Besides detecting and destroying microbes and other invaders, there are other important aspects of blood-type antigens with their resulting antibodies. About a hundred years ago, an Austrian physician and scientist, Dr. Karl Landsteiner, discovered that blood types produced antibodies to other blood types. This explains why some people can exchange blood and others can’t. Thus, blood-type A carries antibodies against type B. Type B carries antibodies against type A. Type AB carries no antibodies against either type A or type B. Type O carries antibodies against both type A and type B. Anti-blood-type antibodies are extremely powerful and can clump (agglutinate) blood cells of the opposing type in seconds. Unlike most other antibodies that require some sort of stimulation, for example, vaccination or infection, for their production, blood-type antibodies appear automatically at birth and, by four months of age, have attained almost adult levels.

In addition to blood-cell agglutination by anti-blood-type antibodies, it was found that many foods agglutinate the cells of certain blood types but not of others. A food that may be harmful to the cells of one blood type may be beneficial to the cells of another. Many of the antigens in these foods have A-like or B-like characteristics. This discovery led to the link between blood type and diet.

Lectins

Which brings us to lectins. Lectins are abundant proteins, found in foods. Their agglutinating properties affect blood and other tissues, organs, and body systems. If you eat a food that has protein lectins that are incompatible with your blood-type antigen, they attack an organ or system and begin to agglutinate cells in that area. Many food lectins are close enough to a certain blood-type antigen so as to make that food detrimental to another type. For example, milk has B-like qualities. If a type A drinks milk, agglutination begins immediately to reject it. Cells in the target area are clumped together and destroyed. However, there is some protection from lectins. Our immune system actually sloughs off 95% of the lectins in our food. The other 5% can cause problems if a particular blood type is reactive.

    Lectins are abundant proteins, found in foods. Their agglutinating properties affect blood and other tissues, organs, and body systems. If you eat a food that has protein lectins that are incompatible with your blood-type antigen, they attack an organ or system and begin to agglutinate cells in that area.

General Comments

In addition to diet, Dr. D’Adamo’s book includes sections, under each blood type, about stress/exercise, meal planning, supplements, weight loss, and personality. At this time I will consider the broad aspects of diet and exercise. The details of these and the other actors are nicely discussed in Dr. D’Alamo’s book, which I strongly advise reading. There are some variations within each type because of size and weight of various peoples as well as geographic variation. Also, people from different cultures and races don’t always have the same frequency of the gene. For example, one type A person may be AA if both parents were A, another may be AO, if one parent was O.

Food suggestions

As to diet, foods are classified into beneficial, neutral, and avoid. These are further classified into fifteen types of foods—meat, fish, oils, nuts, beans, cereals, breads, vegetables, fruits, juices, condiments, etc. Following are a few examples of the three basic classifications for each blood type. Further reading will give the reader all the details.

Type O

Highly Beneficial: Beef, lamb, liver, eggs, salmon, whitefish, olive and flaxseed oils, onions, kale, garlic, spinach, plums and prunes, pineapple juice, to mention a few.

Neutral: Chicken, turkey, bass, shrimp, lobster, butter, goat cheese, cod. liver oil, almonds, pecans, string beans, rice, rye bread, many vegetables, most fruits, most juices, most spices, mustard, mayonnaise, chamomile tea, beer, red and white wine, plus many other items.

Avoid: Pork, ham, bacon, catfish, lox, milk, goat milk, cheese, peanuts, cashews, navy beans, lentils, wheat, oats, corn, white potato, cabbage, olives, oranges, honeydew melons, strawberries, apple juice, orange juice, vinegar, black peppers, ketchup, coffee (even decaffeinated), tea, and sodas.

Type O‘s have a hardy digestive tract and thrive on animal protein. Organic, free range meats are preferable.



Type A

Highly Beneficial: Rainbow trout, sea trout, whitefish, salmon, soya cheese, soy milk, olive and flaxseed oils, peanuts, lentils, black eyed peas, buckwheat, amaranth, Ezekial bread, rice cakes, broccoli, carrots, kale, spinach and many other vegetables, apricots, grapefruit, pineapple, juice of these fruits, ginger, garlic, mustard, rose hips tea, coffee, red wine, and green tea.

Neutral: Chicken, turkey, ocean perch, sea bass, swordfish, goat cheese, yogurt, kefir, cod liver oil, almonds, filberts, macadamia nuts, green peas , snap beans, rice, corn flakes, gluten-free bread, wild rice, spelt noodles, cauliflower, celery, corn, apples, grapes, melons, peaches, pears, apple and grape juice, very many spices, pickles, jelly, dandelion tea, senna tea, and white wine.

Type A’s flourish on somewhat more vegetarian diets.



Type B

Highly Beneficial: Lamb, rabbit, venison, cod, halibut, salmon, cottage cheese, goat milk, skim milk, olive oil, navy beans, oatmeal, puffed rice, Ezekiel bread, rice, kale, cabbage, carrots, and many other vegetables, bananas, grapes, pineapple, grape juice, cranberry juice, cayenne pepper, ginger, rose hips tea, and green tea.

Neutral: Beef, liver, turkey, whitefish, catfish, white perch, buttermilk, Monterey Jack, cod liver oil, flax oil, pecans, walnuts, white beans, snap beans, grape nuts, granola, gluten-free bread, oat bran muffins, quinoa, brown and white rice, garlic, cucumber, white potatoes, and very many other vegetables, apples, peaches pears, apricot juice, orange juice, most spices, mayonnaise, mustard, many herbal teas, coffee, and red and white wine.

Avoid: Bacon, ham, chicken, duck, pork, shrimp, lobster, anchovy, American cheese, ice cream, peanut oil, safflower oil, peanuts, cashews, filberts, lentils, pinto beans, wheat cereals, corn flakes, multigrain bread, rye bread, buckwheat, couscous, yellow corn, all olives, coconuts, rhubarb, tomato, black pepper, ketchup, senna tea, distilled liquor, and cola.

This type diet represents "the best of the animal and vegetable kingdoms."



Type AB

Highly Beneficial: Lamb, rabbit, turkey, salmon, mackerel, sardine, cottage cheese, goat milk, olive oil, peanuts, walnuts, chestnuts, navy beans, green lentils, oatmeal, Essene and Ezekial bread, rye crisp, white and brown rice, broccoli, celery, kale, garlic, grapes, figs, pineapple, grape juice, carrot juice, horseradish, ginger tea, hawthorn tea, rose hips tea, coffee, and green tea.

Neutral: Liver, pheasant, catfish, carp, sole, snapper, skim milk, soy milk, cheddar cheese, peanut oil, cod liver oil, cashews, almonds, brazil nuts, green beans, northern beans, domestic lentils, grapenuts, seven grains, cream of rice, whole wheat bread, multigrain bread, couscous, quinoa, asparagus, carrots, red cabbage, white potatoes, and many other vegetables, apples, peaches, pears, various melons, apple juice, pineapple juice, prune juice, very many spices, mustard, mayonnaise, jelly from appropriate fruits, catnip tea, peppermint tea, beer, red and white wine.

Avoid: Anchovy, sea bass, lobster, haddock, lox, bacon, beef, pork, veal, venison, ice cream, whole milk, buttermilk, sherbet, corn oil safflower oil, filberts, sesame seeds, lima beans, garbanzo beans, kidney beans, kamut, buckwheat kasha, lima beans, all white and yellow corn, red and yellow peppers, bananas, oranges, rhubarb, white vinegar, cayenne pepper, ketchup, relish, fenugreek tea, senna tea, distilled liquor, diet and other sodas.

Exercise Suggestions

The amount and type of exercise recommended is related to how different blood types respond to stress. Each type attempts to overcome stress through a distinct, genetically programmed instinct. The ancient hunter ancestors of type O’s had an immediate, physical response to stress that goes directly to muscles. With a physical release at this time a positive effect may come from a bad stress. Type O’s then are suited for intense, physical exercise.

    The ancient hunter ancestors of type O’s had an immediate, physical response to stress that goes directly to muscles. With a physical release at this time a positive effect may come . . .

The type A person reacts to the alarm stage of stress intellectually, producing anxiety and irritability. As the stress continues, the immune system is affected, leading to further problems. These negative effects of stress can be countered by quieting techniques such as yoga or meditation. Other quieting type exercises like hiking, swimming, and bicycling are also helpful.

The type B response to stress is a balance of types A and O. The physical response of type O and the nervous and mental response of type A complement one another very nicely allowing type B to respond very well to stress. Moderate activities that involve other people, such as group hiking or biking, Tai Chi, tennis, and aerobics classes.

Type AB’s respond to the initial stage of stress intellectually much like type A’s. Exercises that provide calm and focus bring relief. This type would benefit from moderate, isotonic exercise like hiking, swimming, and bicycling done even vigorously. Hatha yoga, Tai Chi, Aikido, and golf are other good exercises.

Conclusion

Specific guidelines for each blood type regarding specific exercises, with time and frequency, are beautifully outlined in Dr. D’Adamo’s book. The same is true for dietary guidelines as well as the other elements of a blood-type plan. Hopefully, the information contained herein will motivate the reader to think about these ideas and, working with one’s individual health practitioner, decide whether or not to implement all or parts of them into one’s lifestyle.

It seems that you refer to the origin of man, while the blood theory refers to the more recent origin of bloodgroup. The "modern" man was primarly a hunter and his brain developped thanks to meat eating. Then some men group themselves in societies to developp agriculture, so they began to eat vegetables/fruits, which changed their metabolism and that's how A blood type appeared. I was vegetarian but as a O, was not feeling good at all, now i feel much stronger. There are loads of O people testimonials such as mine. While the A feel much better when they cancel meat. We're not all the same!

Mmm, this mean that I should quit to practicing the martial art Imua Lima Lama? (I dont like the quiet ones like tai chi)Strange, but, I can be an agressive person sometimes (just when somebody REALY piss me off).Can I made excersises with weights without any problem?

First, are you really sure about your blood group?
Better check with a blood sample, even if it's boring.

Second, even if you're A, you can eat red meat from time to time, drink a beer from time to time, etc...

But you must avoid to consume the harmful aliments for your group REGULARLY and consuming beneficial ones as much as possible. That's all.
You'll enjoy your weekly beer, piece of beef and your tomatoe even more as you take it rarely.
By mixing it with beneficial aliments, you'll limit the harmful effects.
About fruits, The A can take a lot of delicious fruits, and you'll re-discover some that you don't think of usually.
Don't worry, it's just a matter of changing its habits, and it's very easy actually. As soon as you'll remember
what's good and what's bad, you will be careful.

All the A-people i know are quiet persons who don't like violent sports -or any sport at all-, i'm myself a O and i practice musculation with weights and i feel it's good for me.
Now if you're really A and you feel that musculation is good for you, don't worry and keep on. Listen to your body. The most important is to follow the diet advices and see if you feel better.


I'll soon translate the complete list for O and A.

This remember me when I eat a lot of peanuts, I feell with much energy, that's happen a lots of times when I was a kid.


And with one day trying to made a good diet I feell with more energy, thanks a lot .
