What is the population sample size that was used to determine the BTD, and is there a statisticians report that has been published?

Thanks
Mark

which of the books have you read?
there s ample reference given in the back of every book, for you to investigate.

The blood type diet was not developed using a single statistical study.  The ways it was developed and it scientific underpinnings are available on this page:

http://www.dadamo.com/science.htm

Some of the scientific publications related to the diet are listed here:

The concepts used in the Blood type and GenoType diets are explained here:

That information in and of itself would be of little use to you unless you knew other parameters that were used. One sample of 100 people could be considerably more statistically significant than one of 10,000 people.

There are many thousands of peer-reviewed studies that used blood-type and available at the National Institues of Health website, free to look (may require registration).

In Live Right for Your Type, Dr D'Adamo states that he conducted an online survey from June 1999 to December 1999.  A total of 20,635 people responded and of that 9166 were type Os.  

Dr D'Adamo also states that: "This was not a scientific study per se.  Rather it was an attempt to see if I would get results that were more or less consistent with other research.".

Why hasn't the study continued to-date, and why didn't Dr D'Adamo conduct his own scientific study to validate the research findings?

What type of data are you seeking that will satisfy your scientific appetite? Are you a Hunter GT by any chance ;) :)?

SWAMI takes thousands of pieces of data to come up with an individual diet just for you.

SWAMi gets smarter over time as Dr. D collects the data on each of us to refine the diets.

Try a variety of search terms including things like ABO blood group.

I guess I have a lot of questions about the validity of the data, and that's why I'm looking for some scientific data that is stastically significant.  I'm sure I'm not the only one that has asked this before.

Not sure, how would I find out?

Can you explain more how this works?

It is a computer program that every time it gets more data it is able to refine itself further.
Explain? thousands of pieces of information go in to take you specifics to create a diet.

I posted the full thread above but here is a copy of one of Dr. D's posts from awhile back.
Hope you can get the connection. over time the more information it has the better it can create a diet just for you.

Hi Doc,

Nice to see you stopping by..



Here is a basic flowchart of the food selection and physiologic quantifiers that were used in the GTD food selection algorithms. Most of the software was/is of my own construction.

Eventually I'll write a program that breaks it all down by food and physiological process.

Hello, Mark.

Dr D' Adamo's system of diets is a difficult to sort out.  There are four levels of individualization.  If you are looking to understand what people mean by a "Hunter GT", look at the "What is your level of personal discovery?" panel on the store page:

http://www.4yourtype.com/

The individualization at the third "Gentoype" level is obliquely attested to by many studies that report correlations between different pathologies and dermatoglyphics.  The truth is that Dr. D 'Adamo has taken the fundamental "one-size-fits-all" approach of the medical community and replaced it with the practical, polymorphic approach pioneered by his father Dr. James D' Adamo.

There are diets using the "one-size-fits-all" thinking that are successful for some individuals.  Ironically these attest to the success that Dr. Peter D' Adamo has garnered.  When the idea of treating all people with the same complaint in the same fashion is abandoned, the fragmented successes of the "one-size-fits-all" is just a blurred mirror of Dr. D' Adamo's polymorphic approach.  A diet like a “paleo” diet for those with high acidity stomachs, which can leach the calcium from the protein.  A Mediterranean diet, a low carbohydrate diet, a low meat diet, a dairy rich diet, each geared to genetically different groups.

The truth is that the funding of a major nation-wide study is prohibitively expensive.  With all kind of diets in his system, there will be at least one to offend the entrenched assumptions of just about anybody.  If a good study did emerge with substantive, positive results, only the professionals would hear of it - given that the media has a history of ignoring a diet that is more complicated than "one-size-fits-all."  So it looks like a broad, quality study that can prove Dr D' Adamo’s science polymorphic approach against the “unimorphc” is not going to happen - even in the next ten years.

That Ornish, Atkins, vegetarian, G.I. all have their successes, points to a deeper, very polymorphic truth about human health.

What are you looking for?

If it is some sort of all-inclusive study, there is none.

Like most theories, it arose as a way to best fit the observances.

If for example, some physiologic attribute (hormone, enzyme, whatever) was proven to be higher in one blood group than another, and there have been observances of some pathological end-effect associated with it, what more indications should one require?

To test the whole system under rigid objective conditions would require a large number of people, following either a real diet for their type or some sort of sham diet. Because of this, you cannot use people already on the program, and these people would have to be paid, plus the cost of the diet.  We'd have to follow these people carefully for a long period of time (say a year) and we would have to eliminate any other possibly contaminating items, such as medications and supplements.

So we are looking at a several million dollar study. This study would have to be done by a neutral entity, say some university nutrition lab, rather the by me.

So short of this mega-study, what can we do?

Recently I've been collecting breath hydrogen sampling from my patients. This test helps indicate  bacterial overgrowth second to digestive malabsorption. We will probably have some nice convincing datum that eating 'right for your type' improves digestive capabilities and lowers bacterial overgrowth. It's a small study, but it has a good focus and it looks at a generalized parameter of fitness, which is a nice way to gauge a lifestyle alteration.
