blood type diet

I have a friend who has recently been following a "blood type diet". He lost a lot of weight doing it. My uneducated guess was that no matter what your blood type is, the diet you are given will be healthy and moderate but I don't have any proof.

One thought I had was, if you take a random sample from a native population, would you find diffent blood types. Along the same line, why would nature require a group of people ,living in the same area, to eat different diets. It doesn't make logical sense, but again, it's a bit over my head.

If anyone has any good links, I would appreciate it.

blod type diet? Sounds like something for vampires.

Never heard of it, don't think it makes a lick of sense.
 
It's a load of horse rubbish. Proteins on the surface of red corpuscles has no bearing on what diet is ideal for you. None, nada, goosegg, zilch, nought, cypher, nothing, zero, nil. People with different blood types are statistically identical to people with other blood types in every aspect except for with transfusions and pregnancy (see erythroblastosis fetalis in your obstetrics text).

My culture, Chinese culture, began associating blood types with behavioral types and indications for Chinese medicine. This is backed up by (that's right) no research. Chinese medicine, which has been practiced for 1000's of years did not discover ABO antigens until modern medicine. Yet they immediately glommed onto unproved, nebulous classifications of people based on blood types. Presumably because it was a difference that had no apparent phenotypic significance, but was a kiosk for pinning magical notions onto. It was funny because my wife assumed she was B type and attributed her personality to this blood type until she found out she was a different blood type.

It's the same as the so-called "MDs" on late-night infomercials trying to analyze based on your blood type whether you need to eat a diet balanced towards "acid" or "base". They claim that you need to avoid eating too much calcium or whatever in order to avoid changing your blood chemistry to acid. Regardless of this, everyone who is healthy has the same serum pH and nearly the same partial pressure CO2. Because your kidneys and lungs function well, you are able to balance your acid/base easily.

Typical ABO holistic "medicine" voodoo from "Dr." Peter d'Adamo and the woo-woo Blood Type Diet::

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.

Well, seeing as how it's really MHC complexes and antibodies that recognize and alert the immune system to "foreign-ness", I fail to see how this can be true. An antigen doesn't recognize antigens -- this is an exceptionally sophomoric misstatement of how the immune system truly works, but don't expect that to be the last of the egregious errors found in ABO medicine literature.
 
I was surprised to see this in PubMed:

South Med J 1991 Feb;84(2):214-8

Relationship between blood groups and behavior patterns in men who have had myocardial infarction.

Neumann JK, Chi DS, Arbogast BW, Kostrzewa RM, Harvill LM.

James H. Quillen College of Medicine, East Tennessee State University, Johnson City, TN.

Consistent correlations have been found between physical dysfunctional states and blood factors. Some of these disorders have possible psychosomatic components (eg, duodenal ulcer, myocardial infarction). This study focused on the relationship between blood types and various indices of behavior patterns (eg, type A behavior scores, anger ratings) in young patients who had had an initial myocardial infarction. Patients with blood type O scored significantly higher on type A behavior scales and related indices than those having blood type A. Those with blood group B responded on several scales between those with types A and O. We discuss the utility of blood groupings in future research in the prediction of myocardial infarction, methodologic limitations, the relationship of these results to temperament studies, Jenkins Activity Survey subtest patterns, anti-H reactivity pattern, and hypotheses relating blood factors and behavioral traits in patients with psychosomatic disorders.

Of course in the ten or so journals listed as "evidence" for blood ABO grouping and different physiology/psychology (by someone named Peter d'Adamo who provided the incorrect antigen-antigen lecture above) there is not a single shred of information about study design, and even though the studies were published 4-17 years ago, not a shred of this so-called evidence has been replicated. I'd love to pull up this material from the library of obscure crap to get a good laugh but I have better things to do with my time.
 
Thanks for the info (I have to get out my dictionary though).
I was going to have pork chops tonight but I don't know now. I was reading through the "Eat Right 4 Your Type" FAQ (http://www.dadamo.com/ ) and they say this:

Why should all types avoid pork?
Hog is very "A-like" immunologically, which makes it an avoid if you happen to have antibodies to the blood type A antigen, like type B's and O's do.

Paradoxically enough, hog also has an antibody (iso-hemmaglutinin) in its tissues which reacts to the A antigen, so it should be avoided for this reason by A's and AB's as well.

Should I listen to them or this site:

Yet another sophomoric error in basic immunology. I guess he never made it past that class to get his "Doctorate". Iso-hemmaglutinin is misspelled -- it would be "hemagglutinin", and it ain't no antibody. Furthermore, it is interesting that the orthomyxovirus that causes influenza produces several isozymes of hemagglutinin (anybody remember the H5N1 chicken killer in southern China?), but nobody every got a flu-like symptom from eating pork. It's funny that this guy has all sorts of "information" for his dupes but most of the information has absolutely no science behind it.
 
Oh no!!!!

Type A's (40% of the population) evolved after the start of agrarian society and are best off as a vegetarian.

But I love bacon and chicken! This is so bad, now I have to eat salad all the time, or else I won't be healthy.... :D

And I shouldn't drink while I eat? But I get stuff caught in my throat and need some help....

Oh well, I guess my body is in the crapper, I should just take up eating Dark Chocolate and cans of frosting for the rest of my life. :D
