BTD Forums  /  Eat Right 4 Your Type  /  How is Blood Type Research Done?
Posted by: Ronagon (Guest), Sunday, August 6, 2006, 11:16pm
This is a question I've been pondering for awhile:

How are all the various foods studied, to achieve these blood type compatibility findings?

Is the research anecdotal?  Does it rely on people self-reporting?  Are all the various foods tested in a lab, against actual blood type samples?  

Are multiple samples of the same blood type tested, to ensure that findings are not anomolous?  

I've noticed that there are a lot of foods in these books that are catalogued.  Is there one method that's applied to all of them?

I would very much like to know the answers to these questions.

here s a quoted text of Dr Ds answering a similar question:
he has done the testing himself, for the last 20 years or so......
Quoted Text
1. Read every scientific article on ABO blood groups published since 1900.

Pay special attention to studies which describe physiological
and genetic  relationships. This of implies that you must have the requisite
training in immunology, hematology, biochemisty, genetics and pathophysiology.

2. Understand the cellular dynamics of ABO sufficient to develop appropriate

Understand the molecular biology and elemental cytology behind ABH secretion,
gut glycosylation and membrane dynamics. Understand the mechanics of cell
membrane manipulation techniques, such as  basic cell washing techniques, DTT
de-antigenation and membrane electrical zeta potential. Understand and
execute capably various direct and indirect antiglobulin techniques (Coombs
testing).  Possess  basic cytology/histology apparatus (incubators, cell
culture materials) to propagate organ-specific cell lines.

3. Capably and reliably execute various ABO related serological techniques.

Understand and perform capably saline titration of anti A, anti-B and anti-AB
IgM antibodies with serum titer determination. Comprehend and perform
capably anti-A and anti-B IgG1-4 block (ala Kabat and Weiner) titration.

4. Develop proper extraction technique for lectins and other biologically
active food constituents.

Have access to an research grade electrophoresis device and understand
capably the techniques of gel immunoelectrophoresis and immuno-diffusion.
Possess a full range of cell growth adjuvants that allow in vitro lectins to
behave as in biological conditions.  Perform and understand various techniques
of lymphocyte blastogenesis and mitogen studies.  Undertand lectin
specificities and competitive inhibition techniques involving blocking sugars.

I have a question in the same vein (my books are all in storage): if an avoid food agglutinates with the lectin and the blood type, what makes a food a beneficial versus a neutral?

From the BTD FAQ:
Quoted from How are foods determined to be in the beneficial category?

The food does not agglutinate that blood type.
  • The food does not raise the Urinary Indican (bowel toxicity) in that blood type.
  • The food protects against some disease with a known preference for that blood type, and does not show any negative aspects.
  • The immunological design of the digestive tract seems to indicate a distinct ability to metabolize the food well, perhaps as a result of anthropology or other variations.
  • The food contains an enzyme known to react positively with the antigen of that blood type.
  • The food does not stimulate an opposing blood group antibody reaction.

I suspect that that information is a good start, but may be simplified for laymen reading.

I would imagine that it either:

1. helps repair damage

2. does good things in the body on a cellular level via the various components in the food.

I also have some questions.
I just finished reading Dr. James D'Adamo's book "One Man's Food".
He seemed to heal people of different blood types but used a lot of the avoids that are now listed.  For instance for type B he prescribed chicken and also soy but they are now avoids.  There are also others but that is all I will mention for now.
How was he able to heal his patients but now these foods are avoids???
I know there is ongoing research but this really seems strange to me.
Thank you for your answers.

Quoted Text
....he recognized that each of the 4 blood types thrived on certain foods and physical activities. In 1980, James D'Adamo published his observations on diet and exercise patterns for each blood type in a book called One Man's Food.

Two years later, James' son Peter, then a senior in Bastyr's Naturopathic program, began to substantiate his father's theory with objective research.

::) might be that Dr. J. D'Adamo is an SJ or NF (what I guess ENFP/J) and Peter is NT=(E)iNTp/j and
here I am completely agreeing with Lola's suggestion :D :K) and since computerizising's all became much easier& nano techniques....

I suspect he had success with his approach because it was still a step forward, but was not as successful as with the application of the current level of knowledge that Dr. D has made available to all of us.

Back in the day...I remember not a few people swearing by the 'Olde Man'.

But that was before the LR4YT as far that goes.
Since the Secretor Status info came out, most of them mind their Ps and Qs.

I began following the ER4YT diet in earnest one and a half months ago, (I've been toying with it for about a year now). My doctor told me I'm borderline hypertensive,  Cholesteral 205 and HDL 36, and he wants to put me on medication, permanently. I have opted for the ER4YT diet, and over a tree month period, I expect my medical tests to show an improvement in cholesteral levels. A colleague at work is sceptical about the Blood Type diet. He sent me a link to this article at:

In the article Michael Klaper M.D. expresses serious reservations about the Blood Type diet, after having read Eat Right For Your Type. He questions the absence of scientific documentation to back up Dr. D'Adomo's theories, and is very critical about the use of the fundamental ABO Blood types to determine diets for various blood groups. He seems to reject the notion that flesh and meats are beneficial to some blood types.

As a relative newcomer to the Blood Type diet, I am anxious about doing the right things to improve my state of health. Is he correct? And how can his questions and criticisms be definitively answered so he can correct the assertions made in his article?

Hi Lakey,

You can read about his criticisms, and more:
