Not sure if this has been done here already, but I was just wondering if there's any corelation between blood type and celiac disease. All the people in my family who have celiac are AB+ (including me). Just curious. Maybe we can send our results to Dr. D'Adamo (the guy who wrote Eat Right for your Blood Type) and see what he thinks!

thanks

Well, why not? And it doesn't hurt. I voted (A)

I don't think Dr. D'Adamo has done much personal research in regards to Celiac, but he quotes a few studies about it in his Complete Blood Type Encyclopedia. It says that the risk for all blood types is the same (an average risk), but the risk of getting Celiac Disease is high for "non-secretors" of all blood types.

He also talks about different blood type antigens being linked to celiac disease due to their larger sized molecule and how they affect the lining in the gut. He also talks about M cells and patches in the gut where immune tolerance to foods are built. It is an interesting read. It made me go out and get the secretor test done. I am an A+ secretor, so I am apparently at an average risk for celiac disease. All three of my kids are also A+, but my husband is O+.

He does talk about people with the A blood type being more prone to intestinal disorders because of low acid in the stomach and other such things. It has been a few years since I read the books or followed the diet. I did feel better on it, but it is hard to do gluten-free & avoid all the other foods on the list...maybe someday I will try it again.

my daughters are actually the ones with celiac but since we all (my husband, myself, and both kids) have the same blood type, I voted for all of us

O+

I guess us A's are right up there as I am A+.

Blood type tends to be correlated with certain areas of the world (but this is starting to change with easier travel and migration as well as intermarriages/reproduction). Though it was discussed in one of my population genetics classes, I have forgotten what blood types were more common where (I think B was more of a Mongolian type?? that is all I can recall for certain, but I will see if I can find anything in my notes). Anyway, that would explain the relationship between celiac and blood type. The authors of Dangerous Grains hypothesize that those cultures that have been exposed to wheat for less time have the highest incidence (sounds reasonable to me), so if A is a common European-descent type, then there you have it. Also, the ethnicities/cultures represented in this forum may be somewhat biased, so who knows what the results would show if we could survey those in South America, Africa, or China..........

But great idea for the survey, does get a person thinking....

Found the blood type stuff - remember that this is based on frequency data - meaning that certain blood groups occured all over the globe, but were more common in particular areas (likely as a result of the manner of inheritance). Clear as mud? Also, I have no refernce date for this data, so not sure if this stuff was from the 50s or the 90s....who knows, but this would affect the frequencies obviously, as I am sure, with time, things will tend to move toward the middle.

A groups was/is most common in Europe and European decendants, least common in Native Americans (including South America, which had 0% frequency)

B was/is highest in the Middle East, low in Native Americans

O was/is highest in the Native Americans (including South America, which was at 95%+)

Interesting......

A+ also. Only A+ I ever got!

I followed the ER4YT diet for a while and that helped me figure out gluten. Though I was a huge fan of the spelt bread recipe in the ER4YT recipe book I had...
