Statistics are different for polling prediction versus clinical medicine outcomes. Ornish 'proved' his diet in 1983 with a total of 46 people; 23 of whom were not actually on it.

Quoted from 2374

The polls admit margins of error.  What would the margin of error be for the geneotype diet in a sample this small?

You are correct that there is always a statistical margin of error when dealing with sample populations. The amount of potential error is determined both by sample size and also by the inherent variation (standard deviation) of the expected results. In english, this means smaller samples can be much more accurate than larger samples if the underlying thing being sampled is more consistent.

Also a type A may be a nonsecretor, in which case they would need animal protein, which could have been your situation, as you don;t state your secretor status...(which you may not have had tested yet)....also some secreting A's need a bit of animal protein too.....keep asking questions!

I think I do best on mostly vegetarian with occasional animal protein like fish. I do terrible on an O type diet, like Atkins.. I get very acidic, with horrible reflux. Dairy is a bad culprit for acid reflux with me too.  I've tried like every diet out there, Low carb, High carb, Nutrasystem, shakes,
etc. I have been keeping a journal and looking it over, my weight and health was most stable when I was pretty close to my blood type eating. So, now I'm back and pretty sure I'm a Warrior, except my finger measurments have me baffled. I need Dr. D. which I'll see soon.

Good luck!   I was wondering how you were eating as a vegetarian that you didn't do well?  My son's father is vegetarian his whole life and he's a B blood type. He's very healthy.

Quoted from 2374

I was impressed when I read Dr. D'Adamo's list of parameters.  Then I noticed it is based on 980 clients.  Is that all?  Is that enough?

Hi there.  I'm going to echo Dr. D'Adamo's comment here, because I get these kinds of questions all the time as well.

Scientific statistical analysis is different than a simple poll, and here's why:

In a poll, people have to choose one of a number of choices.  Therefore, the more people that take a poll, the more likely the poll is correct- ASSUMING that the people taking the poll are chosen randomly.  They frequently are not.

Participants in a scientific study are not chosen randomly.  They are screened for a specific set of characteristics before they enter the study.  However, once admitted to the study, the participants are randomized to whether or not they are in the control group.

Secondly, a scientific study is generally following an endpoint which is not discrete (as in 1 of 3 choices), but continuous.  For example, in the study cited by Dr. D'Adamo, Dr. Ornish's team found a 44% mean increase in duration of exercise, a 55% mean increase in total work performed, a 20.5% mean decrease in plasma cholesterol levels and a 91.0% mean reduction in frequency of angina.

Because these differences were so great, statistical significance was adequate even though there were only 46 participants.  If there were say, only a 10% difference in one of those values, then more participants would have been required to establish statistical significance.

I hope that clears thinks up for you.

Well Dr. D'Adamo, if that doesn't get down to the nitty gritty of individualization, not sure what does!  

Yellow Doc,

As I am sure you have read, a key feature of Explorers are their impaired detoxification processes.  Reference pages 155 and 156 and your answer will be clear.  Almonds can be a source of molds which interfere with Explorer detox.  In addition, almonds are a high source of omega 6 EFAs.  Improper ratios of omega 6 and 3 can inhibit an Explorers metabolism, as well as interfere with their immune system.  You should note, almonds are not a "toxin" but are a food recommended to be avoided only for 3 to 6 months while adjusting oneself to the diet.

A key point to emphasize here is, like his approach to medicine, Dr. D'Adamo's approach to nutrition is not "one size fits all."  I am sure you have seen this with your own patients.  

As time progresses, Dr. D'Adamo will begin to create tables of data to explain reasons behind food categorizations.  This however takes a great deal of time, as I am sure you can gather from his list of standards each food was versed against.  In the mean time, a close look at the food groups, and a through understanding of each specific genotype will probably lead you to your answers.
I hope this helps!  

Dr. C.

I thought this interesting the idea that Almonds were not as good for us as the ration of omega-3 to Omega-6 is not good, and so being an Explorer on the GTD web site I thought I would check out this theory:

So here goes:

According to the Nutrition site we use:

Total Omega-3 fatty acids in 1 cup of almonds is 5.7
Total Omega-6 fatty acids in 1 cup of almonds is 11462

Therefore 0.05% of the Omega is Omega-3

Now I need to research Macadamia nuts!

Ok here we go:

Total Omega-3 fatty acids in 1 cup of macadamia is 276
Total Omega-6 fatty acids in 1 cup of macadamia is 1737

Therefore 15.9% of the  Omega is Omega-3

Ok Pecans:

5% of Omega is Omega-3 in Pecans!
0.3% Omega in Omega-3 in Pine Nuts

Guess for me Macadamia's win! lol

Really though why are Pine Nuts a Superfood when they according to the theory not a very good ration of Omega-3 to Omega-06!

So you are right when you said that:

In the mean time, a close look at the food groups, and a through understanding of each specific genotype will probably lead you to your answers.

Welcome Lorrainesavvy!!

It is great to see you on the BTD site.

To help us relate to your concerns it would be helpful if you would visit the member center and set a few things.

To do this click on 'Member Center' at the top of this page (or click here, then on 'Avatar Settings' on the left, to select an avatar, to share your blood type with us. (this is shield with an A, AB, O, or B on it)

Add information below your avatar setting, in the 'Profile Information' section, typing in the 'Personal Message box': (Rh+/-, Genotype, secretor status; subtype A1 or A2, MN blood typing information)

You can also create a Signature that will appear at the bottom of every message you post.

Indicate your gender, age, and location in the 'Personal Information' section.

Again great to see you!

Looks like the SWAMI program will provide a lot of clues to why a food is rated badly for a particular person/genotype.

Take a look at the rationales listed in this sample report (for a type O Explorer with a bunch of other characteristics that I will not list here)

interesting....love to have it done....

We can't take for granted how new this field of study is and how many aspects of Nutrigenetics need to be investigated further. If we want to move individualized medicine forward, we will have to become guinea pigs to an extent.

I watched the Barbara Walters special on Living to 150 the other day and I thought it was bizarre that anyone would want to be cryogenically frozen with the hope they could live practically forever in some utopian future. I'd like to point out that we need to confront the problems that could destroy out entire planet before we can even hope to get to that utopian future, and besides, this has got to be the most exciting time I could hope to live in. If you froze me now, it would be like sleeping through the 3rd Act of a Shakepeare play and waking up wondering why Romeo is in so much trouble.

I want to engage in the world and the mistakes and disappointments are all a part of that, and the triumphs as well.

Quoted Text

see how values can change when one migrates from the BTD values to the GTD system. Somewhere in the allowable GenoTypes for people with type A blood, there will be that old BTD avoid, however, if it is not in your new GenoType values (or if it flipped to being actually beneficial!) it is because its BTD avoid status was less relevant than the benefits it provides under your new GTD skin.

You're so right, Lola!

The vegetarian question for type O's and B's is a complex one. Here's one example. My Mom is type B Explorer like I am (I have told her about the diet but she doesn't follow it). She said to me the other day, since she became vegetarian her acid problems have cleared up and she can eat oranges and berries. Doesn't this mean eat is acidic? I answered that grain-fed meat like common ground beef is certainly acidic. The cattle fed on corn develop acidosis with intestinal ulcers and are basically moribund when they are butchered. It fattens them up quick, but is terrible for their health.

I'm trying to emphasize wild and grass-fed meat in my diet. If my Mom is doing well avoiding grain-fed beef, pork, and chicken, then she has unintentionally adopted some aspects of the diet. Since we are all ultimately responsible for our own diets, sometimes just helping a loved one to make one change for the better is enough.

My first experience with the Blood Type Diet was in the late 90's, and some time after the first forum was established I started using it. Due to computer issues and other distractions I was on again/off again, and when the format changed I found it  less useful. (I know more computer-savvy people probably liked the change, but it took me a while to get up to speed.)

However I have been doing the BT diet all these years and have recommending it to others all the time. I know many people who really got a lot out of it. I saw major changes 2 weeks into the diet, with my joints, my energy levels, my tolerance for reduced sleep, and a host of other things. As soon as the Genotype book came out I ordered it through inter-library loan, and got a copy within the month.

As an O Explorer who tried to be vegetarian both as a youngster (16-19) and during the mid 80's up through the time I discovered the diet, I wish I had known all of this then. Knowing my Genotype has just made things better. I can feel even more of a difference than before, and it really explains why I could cheat on some things in the past, but not on others.

Like Yellow Doc, I want to know it all-- everything-- all about all of it. I'm not a scientist, and don't have time to do gobs of research, but I can't wait to find out more about the whys and wherefores of the foods. As one poster commented though, some of it is common sense-- the almond/mold thing had already occurred to me, but I didn't know about the Omega 6s being high for almonds. It's these bits and pieces that are so fascinating to me.

Given my success with the BT diet I was glad to try any refinement of it-- it only makes sense that the more we know the more there is to discover. The universe goes on and on...

Thundering gerkins !

The amount of information Dr.D uses is staggering. I think that's conclusive enough.
Since I've read his works I look at food in a totally different way. One persons food could well be anothers poison.

Quoted from Mayflowers

Good luck!   I was wondering how you were eating as a vegetarian that you didn't do well?

It may be difficult to get enough protein without soy if you are active sort of person. That is, if you don't fare well with soy. When every available kind of protein pack loads of carbs as well like say peanuts your diet turns very easily into carb overload, particularly if you have sweet tooth like I do. I felt a bit drunk really most of the time. Well, I guess for me even the non-sec type A diet wasn't strict enough as far as vegetable protein is concerned. I seem to need some guide lines to do something as simple as obtaining nutrition

Quoted from Dr. D

The bioinformatics part of this whole thing is just about as exciting as the epigenetics (and even maybe more beautiful?)

You know you've got a problem when you start thinking that bioinformatics are beautiful. Only Dr D could be so audacious.  

You've really got to get out more Doc.  

working like a health practioner, so I use the *Vegatester*(bioresonance) to look for foodintolerances etc....Dr. D. was nearly 98% right in his recommendations of lr4yt .....then explorers appeared and now it's clear why they don't have big reactions  even as being B Rh - and eating chicken... ....I remarked only AB's and B nomads do heavily react with chicken.

What is amazing to detect, after a certain while of not eating a certain food....(1-3 months or more) often people are able to tolerate those foods again.....when they reintroduce them to their diets.
So here might be the causa..... but what is the real issue
beyond this fact.....as Ribbit wrote, she wasn't anymore able to digest wheat propperly and now no problem.... .....
but I wouldn't recommend to any O nor AB to consume wheat again....

I have a question.

It is plainly obvious based on the number of parameters Dr D laid out earlier in this thread that it will take a looooooong time to put together the facts and figures for the genotype food database.

So my question is, how can we help?

Is there any way for us to assist the Doc in this task, such as doing the "gopher" work on this monumental job. Obviously as lay people the medical/technical aspects would be too important to entrust to us but surely there's something we can do (like the repetitive work) that can help the poor guy. I mean, does he ever sleep?  

the best way to help Dr D is by following the guidelines as closely as possible and reporting results......that to me is the best feedback we can give, like the patients who visit his clinic.

......ahhaaa....

I had a similar question about celery.  In the BTD listing on the website for celery it is marked as beneficial or neutral for ALL blood types, so it's not bad for anyone. But in the GTD book for Teacher type it is an avoid food.  That confused me, because if it was universally good or ok for everyone, then why did it become an avoid food for Teacher.  I happen to like celery a lot and eat a vegetarian diet that uses it quite a bit and up until I read the GTD book thought I was not doing my body any harm by eating celery, since it is beneficial for Type A

welcome!

there s too many variables Dr D takes into consideration when typing foods...glad you are now here and can read all about the differences and criteria used in the process.

One more question, (although I never really got an answer for what compound in celery make is an avoid food for Teacher).  In the BTD diet there were guidelines for different racial background.  I am middle eastern and food listing to me look more like a western diet. If the GTD is based on our ancestral genetics as well as fetal conditions, then would it make sense that you should eat food from the region your ancestors come from? There are plants, fruits, veg in the middle east indigenous to that region that grow no where else. My traditional foods use those. Naturopathic prescriptions (Unani or Ayurvedic medicine which both have their roots in traditional persian medicine) include these plants and foods.  For example Salmon, is not a fish you see in the middleast.  We have a number of other fishes, so can I conclude that the food listing in the GTD are really meant for a westerner?

First, Dr. D. hasn't published specific rating information for most foods...  He is busy seeing patients, reading new research and working on further research, development, and refinement of the SWAMI to help more people.

Second, I assume he either uses foods that are available to him or foods that have been included in other peoples pertinent studies...  If the foods (fish specifically) that you are talking about haven't been studied and/or he doesn't know about them, you can't really expect him to include them in the book.  I know he does utilize some information from Ayurvedic medicine in his recommendations, but that doesn't mean he is familiar with all of the various foods that are only available in that region of the world.

While ancestoral genetics are not directly used as input into the calculators for the GenoType, ethnic heritage is considered in determining SWAMI diets, along with DNA haplogroups.

Ayurveda ratings of foods can be used as a factor in determining diet in the GenoType edition of SWAMI.

Often times with fish one has to determine the scientific name of a fish and then figure out for that scientific fish name, what the United States Department of Agriculture (USDA) would call a fish.

Data from the USDA was used in developing the food lists.

The fish names have to be adapted even in English speaking Western countries, because fish names are not consistent.

----

The USDA was not the only source of data for the food lists, and many of the foods listed are not easy to get in the United States.

You will find that with some translation of names many of the foods are included.

You may have to look at other GenoTypes to determine the complete list of tested foods.


----

I live in the US, but there are a number of food products that I eat that are not liste. I generally try a small quantity of these foods, and if I do not have adverse reactions after eating a food, I assume it is neutral.

----

I am not expecting a new book with updated lists in the immediate future.

-----

I think it is more likely that the foods listed in SWAMI will be expanded.
