There are four blood types and each is a blueprint for the human body.
Thanks to the work of Dr. James D’Adamo, we know that the first blood type was Type O – the hunter, a meat eater.
Next came Type B, introduced when grains were harvested and communities were developed over the nomadic lifestyle.
The third common is Type A, found primarily along coastlines where the main diet was from the sea or land.
Last, and most recent, is the least common, Type AB.
So what does your blood type mean if you have Celiac or are gluten intolerant?
Chances are your blood type falls into either A or AB. Now, that’s not to say that gluten intolerance can’t happen in Type O and Type B.
It can and does.
Dr. D’Adamo also discovered that we have a sub-blood type.
So a Type O blood type individual can also have a Type A sub-type. That sub-type has the power to influence the dietary needs, exercise, meditation, nutrition and more.
Are you confused yet?
Well, it’s understandable because most people have no idea what their blood type even is. And that’s like not accepting your personal copy of “Your Body’s Personal Instruction Manual”.
The reason for this original research from D’Adamo was due to the randomness of transplant patients surviving or dying – after receiving a new organ.
It was discovered that the blood is a blueprint to the human body. This is why we now know that there is only one universal donor.
This knowledge alone has saved thousands and thousands of lives.
And now it can benefit you on your own search of enlightenment when it comes to living gluten free.
You see each blood type has specific foods that should be avoided and others that promote health.
In addition, blood types showcase differences in personalities, interests and so much more.
To give you a taste of what each blood type entails, we’ve created a summery that may help you on your gluten free search.
Each blood type has a different degree of stomach acids and enzymes, which are released when food enters the stomach and digestion starts.
Certain blood types have a higher level of acid while others lower. That acid level allows foods like meat to be digested. In addition, that acid level also plays into how gluten is broken down once ingested.
Type O is typically able to eat gluten with little to no effects immediately seen. However, over time certain aches and pains, swells and fatigue can be attributed to the build up of eating gluten (and dairy – but that’s another conversation!).
Type B is able to have very small quantities of gluten, but preferably higher-grade grains.
When our ancestors began to cultivate the land and plan grains they started with different varieties that did poorly in windy areas, were not tolerant to the scoring sun or soaking rains. Over time wheat was discovered. A grain that could withstand the wind, rains and sun plus it turned out to be cheaper to harvest.
Unfortunately, this grain was not the healthiest of grains. So even while some Type B’s have a tolerance, others can also experience bloating or mild-flu-like symptoms or other setbacks.
Type A and AB are both intolerant to gluten and D’Adamo has been known to state it’s like poison in the body.
Over 30 years ago, D’Adamo wrote “One Man’s Food Is Someone Else’s Poison.” When it comes to gluten, that’s the whole truth and nothing but the truth.
So do you know your body type?
I encourage you to find out and if your interested in learning more about the Blood Types and how they relate to gluten, please post a comment below.
I would be very interested in finding out more about blood types and diet, how it affects personality and more!
Thank you
I’m a type A and very very gluten sensitive. I’d like more info on this please! Interesting!!
You know, it’s great that you mention the importance of knowing your blood type, and it’s a shame that most people don’t. Your explanation for why you must find out your blood type is very convincing and what you wrote here about blood types and it’s tolerance or lack thereof for certain foods should be put in front of every living person today.
I am a type O but am at least gluten intolerant and have a daughter with Celiacs Disease. I must be a sub-type B. How would you find this out? Is there a test for it?
Hi Linda, The sub-test is something D’Adamo does and when I mentioned it to a medical doctor during a regular checkup, I was promptly told there’s no such thing. I smiled and said no more. At one time, there was no such thing a blood types and now we know differently. At one time the world was thought flat and now we know differently. Science, medicine, is forever growing and changing. I am sure there will be a way to test for the sub type soon. At this point, it’s rather easy to tell based on characteristics you might have. From how to learn to how you exercise, to your body type to you eating habits and even what you do in life (your purpose – some call it your job). We will write more on this topic as it seems to be of interest to our readers! Let me know if you’d like more. Best, ~J.
I agree Gluten Free! This is a passion of mine and I’ll likely write more as there seems to be interest. Blood type really is a manual for your personal body, personality and health. Amazing stuff. I’ve spent years researching it and it actually saved my life (D’Adamo’s work and eating for my blood type). The body is able to heal, when we allow it. ~J.
Yes Jenn, I am VERY interested in learning more about this. I sort of learned accidentally by doing the low carb diet that I’m gluten intolerant, but also, I tested negative for CD because I wasn’t eating carbs (ie no pasta, bread, etc.). Every time I went back to the old way of eating the tummy issues popped up (literally!). I am curious about the exercise/blood type too, as I struggle constantly with that. I walk hours a week and see no results body wise. I’m currently at about 16,000 hours of walking so far this year (I keep track at sparkpeople.com).
Thanks for the help!
Hi Stephanie, thank you for your interest and excitement. I love this topic too! It is interesting and really amazing. I’ll definitely write more. I too am Type A and to give you some quick insight – Type A leans toward a vegetarian diet (makes you feel better eating this way where as meat might tend to make you feel heavy and is hard to digest) and an A tends to be of the mind. Meaning, for instance, that I, as an A, am constantly in my head, a thinker, a scholar (not necessarily smart) but someone who loves to learn.
It’s important for an A to take time to meditate and get out of the “head” and be in touch with the body. An A can easily run his or her body ragged without thought because they are so focused in the thinking of life. They are often excellent teachers… Do share if any of this sounds like you. I would be curious to know if this resonates. With anyone reading. Please do post a comment. There is so much more to share on this topic. ~J.
Hi DJ, I will definitely will talk more on blood types. I am so glad for the interest. Thank you for sharing and please stay tuned for more to come!
Warmly, ~J.
Your comments are so interesting. My life has revolved around these topics for years. I didn’t know that blood types A and B have more gluten intolerance, but I have read that there are more gluten intolerant non-secretors of which I am one. I have been on the AB blood type diet for over 3 years. I also try to serve only whole foods and run a gluten-free kitchen even though I’m the only one who must remain gf. A diet combining GF, BTD, and wholefoods is a challenge. (Complicated by feeding a family of Os and occasionally an A and some Bs.) It’s hard enough to find foods that are safe, but the choices are really limited by my AB non-secretor list. My own taste preferences have been mostly ignored, but I’ve learned to like many new foods!
Cross-contamination prevents me from using many bulk foods, even from a wholesale source. I called one and was told that they try to package the gluten-free products first and then on the same table they do the gluten products. Do they wash aprons, how do they deal with airborn gluten settling on equipment, are they really aware of the hazards? etc? I want to find a resource that lists safe bulk food sources that don’t have the 2% or even the .2% fudge factor, or better yet, doesn’t deal with gluten products in the same building.
I’d love for you to share more.
I am very interested in learning more about this. How to find out what type I am and how I need to adapt so that I feel better. My three daughters and I are gluten intolerant.
Very interesting info!
I have type A blood and am gluten intolerant. It took me several years of different practitioners before I figured this out (and accepted it!). I have been tested for celiac disease twice but it was negative. I think this is true because I can tolerate some gluten and can eat sprouted grain breads. As you mention, I am definitely “in my head” and love to learn. My brain never shuts off, especially when I sleep (lots of dreams!). I have been trying to meditate and write in a journal to get my thoughts down and out of my head. This is not easy! And I could never be a vegetarian. I am trying to eat more vegetables (I love fruit so I guess I’m half way there?) but I know I don’t eat enough. Oh yes, and I am casein intolerant (or allergic, not sure which) which really makes my diet challenging. I love my bread and my dairy. Ugh!
Hi Jen,
I am very interesed in finding out more about how blood types and gluten intolerance affect each other. I am type A- blood and found it very interesting what I read so far. I was diagnosed with Celiac Disease about 3 years ago.
You mention blood type but I see no info on it. Please tell me where to find this info, I’m curious.
What you sent is fascinating. More please.
I am AB negative. Does negative or positive have anything to do with gluten problems or even personality? I didn’t find out about my gluten problem until age 60. Doctors diagnosed every digestive problem in the book all my life. I finally got to where I ate only toast when feeling lousy, great huh?
Jen. This info is totally amazing. I never knew blood type had anything to do with CD. I am type O and your description of people with this type hits to nail on the head. I had almost NO symptoms for the longest time. I only found out by accident when I had an EGD and they found irritated stomach lining and did a biopsy. Wow. More info will be welcome. Thanks
Pamela, we will be posting more. There is a lot of interest and people simply don’t know! So thank you for commenting. We will be bringing you more on blood type. It’s especially great knowledge to know for family members or children…. from what foods are best, to exercise, to personality traits, to learning style – blood type gives us so much information. Stay tuned for more! ~J.
So, are you saying all type A and AB have gluten intolerance to some degree?
Could this explain naturally high cholesterol in people with those blood types? And why these people who move to a low carb (naturally lower gluten) diet tend to impove their cholesterol levels?
I would like more information. I’m O+ I’m a delayed reactor to everything! I’m also allergic to dairy, corn, soy, nuts, eggs, yeast.
Thanks!
Melissa
HI Melissa, So many of you are asking for more. More to come! And yes, O types are delayed but when it hits, ouch! ~J.
Hi Dusty, there are some people (blood types) that have shown to be more sensitive to foods – like gluten – than others. The current wheat or gluten used today has been stripped of most of it’s healthy properties to make it very hardly (easy to grown and harvest). Not easy to digest. There are other grains, that have been untouched by man, that even A Blood Types are able to consume – those who have gluten intolerance. A test was done not long ago after a ship was found with grains on board more than a hundred years old. Fascinating stuff. So, on the blood types, basically for an O, they have a more delayed reaction to gluten or dairy. They might feel the effects later in life with joint pain, arthritis, etc. However, an A Blood Type will feel it immediately. They might get colds easily (lowered immune system). They have aches and pains, congestion, yeast, etc. They are more sensitive. As is the AB. Now that’s not to say that a B Blood Type can’t also be very sensitive because remember we all have SUB blood types. So if a B has a strong A SUB type, then they will be more easily effected. Same with an O who has a strong A SUB type. As for high cholesterol in some people, while I can’t give out medical advice as I’m not a doctor, what I can say from all my studies and my own experiences, is that some people (types) break down foods differently which turns them into sugars which affects other organs (adrenals), etc. So if your body is not able to break down gluten well, there will be a reaction somewhere – high cholesterol is one such reaction. The body is really fascinating and there is a wealth of information. I’m thrilled so many of you show an interest in Blood Type and how it relates to gluten/Celiac. ~J.
