The blood type diet has been in the news for years as many celebrities swear by it.
But is it the end-all-be-all?
Despite mixed reviews, most of the participants claim it works for them.
The only problem that I see is that we are not being presented with a lot of information regarding rh negative people and whether or not our common ancestry may cause us to be more sensitive for certain foods and crave others more.
According to The Biotype Diets:
Biotype Rh-negative is a Basque biotype. This type has inherited a Basque gene for blood type Rh-negative from ancient ancestors in the Pyrenees Mountains of France and Spain. Their ancestors adapted to their specific ecosystem over long periods of time in isolation, and modern Rh-negatives have inherited those adaptations. They fare best with a temperate hunter-gatherer diet of Western European foods, such as meats, poultry, seafood, roots, tubers, and European fruits and vegetables, nuts and seeds.
Here is one example:
Peanuts are from North America and have not been introduced to Europe before America was officially discovered. It also appears that natives of the Americas are likely 100 percent rh positive. So is it a surprise that rh negative people react the worst to peanuts?
The Biotype Research shows that blood type Rh-negative has more IgE allergies than Rh-positive. In fact, Rh-neg has the highest rate of immediate allergies of all blood types. The graph above is an example. This biotype especially reacts to nuts and beans, but also to eggs, some meats, gluten grains and nightshades, as shown below. Their worst allergen is peanuts, a native American food. IgE Scores of 500-750 are mild, 750-1000 are moderate, and 1000-1250 denote strong allergies. Blood type Rh-negative also displays delayed allergies, including: strong IgG allergens, and some T-cell allergens. (Not shown.) For more on this type, see the Biotype Diets book.

The Blood Type Diet was not quite right for me, but despite this I persevered with the A-type vegetarian diet for quite a while. I read the BTD books many years ago and they made perfect sense to me, so I couldn’t understand for a long time why I didn’t do as well as expected. Gradually gaining more information along the way and determining that I was Explorer Genotype and also Non-secretor changed much for me. Soy was removed from my diet and some red meat was put back in. I do better gluten-free with less of all other kinds of grains. Nightshades are out (usually the mainstay of the vego diet) and there’s a leaning towards Indian food, rather than the Western European foods I was brought up on. Almost all vegetables and many fruits (including tropical) are good for me. Explorer genotype is the only one which can be any blood type at all (unusual fact no. 1), so having much more than their fair share of blood type A (55 out of 105 of our Explorer group members) would have to be unusual fact no. 2. Unusual fact no.3 is that, despite the fact that Rh-‘s are a minority group, we have 45 out of 105 members in the Explorer group who are Rh-. We also have a much larger than average number of Non-secretors in our group as well, despite their being only 20% of people on the planet (unusual fact no. 4). The only dietary consideration for Rh-‘s is in portion sizes on the foods lists. I’ve always felt there’s still a gap in the diet which should be filled with information for Rh-‘s, but who is going to bother with the stringent testing for a minority like us. I know the basic BTD was designed with Rh+ and Secretors in mind so have had to navigate my own way through the rest of it. Having reached this point I know my body pretty well now and will perhaps make minor adjustments as I get older. Avoiding chemicals, including modern medicines is also imperative for us all as these seem to impact on us in many negative ways, including the proper assimilation of even the best quality foods.
Do you have a list of foods beneficial for A- and foods to avoid to possibly share? I am confused with ADamos A diet and now reading about Rh- factors and not sure what is good for me and what is not. Thanks.
Do you have a personal list of foods which you crave on a regular basis?
Do you think that cravings could be foods we should eat or should avoid? The A type diet seems to include things which the A- should avoid and now I am confused since Adamo states that the rhesus factor is irrelevant, however I also feel that it should be considered. Is there anywhere a detailed list of all food categories for type A vs A-?
Thanks!
Your body is not lying to you. Advertising is lying to you and our minds are conditioned to where we no longer listen to our true cravings. Artificial flavors are also misleading. The best thing to do IMO is buy fresh and natural foods and then consume from those what your cravings tell you. As for the “blood type diet”:
I know little about it and from what I read I disagree with too much for me to take it seriously enough to promote it. The claim that blood type O was first for example is unreasonable. But there are many readers here who love the diet and overall it seems to improve people’s health. So I am hoping that someone will answer this and help us all achieve better health and more happiness. Regardless of whether or not there is a specific formula that should overwrite the “voices from inside”.
Interesting that you mention such a high percentage of rh negatives being in the blood type diet group. I am assuming the vast majority being women being that rh negative females are more likely to know their blood types than the rest of the population.
About having to find your own way:
There is no doubt that information is missing as “rh factor is not that important” is not something that rings right with me.
I have come to believe that while our dietary needs might be similar, we could react a lot stronger to the differences between what is good for us and what is not good for us. At least in my case consuming value food in the morning starts my day off well and makes a huge difference. I used to think I was imagining it. Now I listen to my inner voice and my body and know it to be right.
Pork I avoid completely. I try tot eat a lof of fish and turkey being that farm animals are just the degenerate versions of the much healthier wild game while fish being its original version and domestic turkey not being too far off from the wild turkey are more or less what was good for our ancestory and what animals consume themselves will affect those who consume the animals.
Here is an excellent article on that: Health Benefits of Grass-Fed Products
Thank you for your feedback!
Hello,
I am 30 years old and was born in Balkan.
I have to say, I am bloodtype A negative and I never had any kind of allergies or special diets. I always ate what I wanted and my weight anf blood is totaly fine.
So, not all of us need to get allergies or special diets or start worrying about their Rh neg.
Yours Ayla
Thnx ayla same here.A-
I am also A negative. Eat all foods. I am 78 and going strong. Exercise daily and golf and am active. Think I will keep up my lifestyle after reading about the special diets keeping in mind the recommended diet as a guideline.
I am RH Negative. I always ate what I wanted too! No food allergies, No weight gain (107 lbs.) until about 27 years old, when i began taking a medicine for a rash ( periactin), and the side effects obviously slowed my metabolism and I began to gain weight. It was good at first, I welcomed the weight, but NOT good now, lol. I welcome a diet to bring my weight under control.
Same problem(A-) No allergies went back to original weight after 2 children 11months apart. Late 20’s I had to go on steroids for 2 months to combat a massive poison ivy(i am very susceptible) outbreak. I have not been right since. Massive weight gain. Went to the gym for 6months with a trainer and lost 6lbs total. Changed diet. All natural very little to no sugar. I felt a little better but no weight loss. Had major abdominal pains went to numerous doctors. Told me to take Tylenol and said I was getting older
. Recently had a third baby girl who was perfect but a rough pregnancy lots of pain. As of now, my ab pain is gone. I lost all baby weight (16lbs)went exactly back to original crap weight and the struggle continues. I have read about drugs really affecting RH neg. people. I also have the “why” trait like the articles say and I think that is what bothers me most . Not knowing. I could count on one hand the number of times I have been to a doctor before that issue. Also, I have had to remind all of my doctors(even OB) about my RH factor and not one has ever even brought it up. I am 35 and have just started looking into it. If it was not for my mother mentioning it when I was pregnant with my first daughter I probably would never even know. I never knew it was even a rare thing until a few hours ago.
Periactin is given to children in the United States for being underweight. I can’t believe you can’t get another med?
I agree from my own experience. I’m AB rh negative, and can eat all food with no issues. No allergies of any kind & no intolerances.
I choose not to eat meat for compassionate reasons, but could happily eat all meats too.
I like this statement. No propaganda, just specifically stating your reason why you don’t eat meat. 🙂
I am A RH NEGATIVE, I am allergic to a lot of antibiotics and many over the counter medications, I have bad stomach problems from when I eat bread, cheese, eggs and bananas, I have two sisters, my dad and my grandma with the same blood type and all have stomach problems and allergies to many medications, I heard about this blood diet 2 days ago and thought I would start looking in to it, only to find for me and my family it makes a lot of sense.
I would just like to understand more about it and will probably research it until I understand it.

Except pork… never ate that
Hi, same here I am happy to report I have never had to question my diet. I am B rh-negative aged 49 and have always ate a varied diet, enjoying all types of food and happily with no adverse reactions to any particular one (nuts I love and have eaten them from childhood) By some fluke too I am just a couple of pounds over the weight I was when I was 18 but for how long who knows! . . So happy to report no special dietary considerations followed here anyway:-)
Carole R.
I am Type A with Rh-negative factor. I’m now 68 yrs. old. Up until I was about 40, I ate anything I wanted and stayed a size 4. Then I went through the change and started to gain a little weight. Over the last 8 to 10 years, I’ve not only gained weight that I find almost impossible to get off, I have developed allergies to many foods and chemicals. I have learned to identify many of the foods that my body doesn’t tolerate and try to stay away from them, for the most part. When I do “cheat”, I really pay…esp. when I eat anything wheat! I’m so tired of feeling bad, having indigestion and inflammation in my body, I have decided to try the Blood Type Diet. I have a question for anybody who knows. Can we eat good quality organic dark chocolate in moderation? I’m addicted!
I have a daughter in her late 30’s with RH negative and AB negative blood her dad was Italian and his ancestors were certainly travelers. I believe in natural healing and have been working with her weight and digestion. Found out that people with Rh Negative need more oxygen and their bodies to be more Alkaline. There is one fun and simple way to do this, and it’s cheap: Natural Maple Syrup or even Pure Vanilla and making a glass up with water and Baking Soda and putting in 1/2 teaspoon or less of the Vanilla. Oxygen buildup: Lots and lots of Vitamin C in juices and even Iron both bring in extra oxygen. I also found out that many Rh- people are Anemic, sluggish. Vitamin C and the iron help build red blood cells. and really several B-Vitamins especially Choline and Inositol. We are all basically from the earth and need minerals found in the ocean. There really are several places where you can get these all Liquid or Powder . Drink up your health. Cook or stick in your food Coconut Oil. Oil up your brain and your body with good oils that taste great and your heart will thank you. Like I said my daughter had also Digestive problems, the Coconut Oil trick helped her and then for her weight: Fiber up! My daughter is loosing weight, feeling more confident. All I can say is: stay away from anything GMO, Artificial Sweeteners that are now being manufactured in China and India. Look it up, and you will be amazed: Who manufacturers Artificial Sweeteners? Go to ThriveMarket.com and you’ll find absolutely delicious and delightful food. Love life. Make your food colorful. You just have got to see: Create TV.com. Fun, Exciting, passionate food from around the world. Try something different that can perk you up! RH- negative people are very very special people, You are very needed and wanted in this world! Stick Coconut on everything and SMILE!
Love life! Turn up the music and dance and dance!

Allison Lee Sears, thanks for the food we should eat information and the encouragement. I am African American and RH Negative.
I did the blood group diet for a few months and saw little to no weight loss. It doesn’t take into account if you are RH positive or negative and I did ask in a FB group at the time.
I have spoken to several scientists about the blood type diet and all have given me the same answer:
“No scientific basis, but since it forces people to eat healthier, it CAN work for some people”
I have asked this question many times and always been told “rh factor doesn’t matter”. All other factors seem to matter. Being a secretor, what your “genotype” is (not genotype as in AO, BO etc., but rather a newly invented phenomenon) and much more.
IF indeed blood type indicates ancestry, then rh factor should top the list considering our ancestry is likely different in terms of origin.
Eat fresh, eat natural, stay away from anything man-made like bread and pizza. And then let your body tell you what it craves.
Hello, my type is A Rh- (38 years), vegetarian for 6 years (never felt better!), and also (surprisingly) no food allergies.
B- no food allegies at all
I am Rh o neg and cannot tolerate any deadly nightshade foods and dairy , within the kadt 5 years I have become intolerant to all meat and sea foods I am 67 years old female
50 yr old, female, O neg.
DNA: 18% Irish, 82% Western European (according to Ancestry)
Growing up I was always anemic and skinny so I ate whatever I wanted with no problem.
While living in Belize I took Paludrine (anti-malaria med) and after two years I would get hives whenever I ate beef!
3 years ago I got hives that would not go away for 10 days even though I was not eating beef. Allergist said I was allergic to WHEAT, not beef. But wheat allergy prevented digestion of beef and body reacted with histamine.
Also now allergic to avocado, latex, mango, walnuts and coffee.
56 year old female, A-
I’ve never had food allergies and could eat anything and did! Within the last several years I realized that some foods caused bloating and made me feel absolutely terrible. After seeing a primary doctor and having a few blood tests for allergies–tomatoes turned out to be the primary culprit–weird thing is I craved them and would binge on salsa or anything that contained them! I decided to take testing to the next level and go to an allergist. I discovered this website because I’m looking into the Neg RH factor + allergic reactions more–before I see the a specialist. Wish me luck, hoping to get some answers.
I am 51, A- I never had any allergies to any foods until maybe 4-5 years ago. Mostly sensitivities. Mostly to wheat/gluten but have realized i do better with no grains. I have no problems with nightshades except for tomatoes..they go right through me! I have always avoided medicines and chemicals as much as possible. Have a sensitivity to anything that is a stimulant like caffeine and even herbs like St John’s wort. I also have a severe reaction to MSG. I have been doing research trying to figure out something that might help me lose weight. Ever since i quit smoking 11 years ago the weight just keeps coming on..seemingly with almost no changes in diet it has been a huge struggle…and even though I lift weights and do cardio 4 some times 5 times a week it simply is not budging. Keeping my calories less than 1500 per day..usually closer to 1100-1200. So frustrating when in my 20’s and 30’s it would come off..even after my 6 children. However, the note that I saw was that A’s have a tendency to create more cortisol and also during the menopausal changes with the lessening hormones, cortisol is one of the biggest battles as well. So double whammy. I have been listening to my body..and for some reason it has been craving yoga..and after reading that Yoga and Tai Chi are the best forms of exercise for type A’s i think I am going to give it a go..and see if that helps. I had some suspicion that i was over training..and what worked years ago was going against me… *sigh*
Im o negative 53 yrs old and never had allergies of weight issues even after two kids. I like to swim and skateboard and take cod liver oil for the vitamin D so when I fall off my board Im good to go again after a day or two, I eat all organic…mostly crave proteins barely eat fruit. I had lamb and sliced pears so far today. Seems in this post people have gotten allergies later in life. I strongly believe it is from our toxic food..gmo, pesticides, growth hormones, toxic waste, etc and its effects are showing now.
Thank you so much for these articles, and this great site! So much info, much needed and much appreciated. xxx
I’m an RH negative and I’m doing very well on the vegan lifestyle. I never liked western European fruits only tropical. Without meat I have tooooooo much protein, I must decrease it somehow
“type Rh-negative has more IgE allergies[..]Their worst allergen is peanuts” I can eat tons of nuts, no allergies.Bio-individuality is the most important, we all have to find out for ourselves what is the best for our body
I am reading here about foods for Rh Negative factor. It states European Fruits and Vegetables. What are those?? Please email me with a link or a list.
I’m RH O-, very, very ill. I have SLE & skin Lupus. I am not allergic to many foods but I am on Lupus diet and avoid red meat & pork as well as night shade veggies as they, naturally, cause inflammation. Since most of your immune system is in your stomach, I try to avoid things that are hard to digest, as well.
I, CONSTANTLY, crave more protein, when I cut out meats, and try to eat only fish. I want red meat or turkey. Interestingly, even adding fiber to my shakes, protein always comes back low!!! I have always eaten far more protein in my diet, and I eat a lot of fruits & vegetables. I eat well… occasionally I go off deep end & eat chocolate or cheesecake:) I only became quite sick when I got pregnant, at 36, w my only O + child.
I am RH negative and I am allergic to almost everything and I hate it. Eggs I usually request only egg whites which I seem to tolerate just fine. I have awful gas and bloating with cheese, milk, soy, peanuts, and tuna bothers my stomach too. I also have bloating with bread especially wheat bread I can eat almonds just in moderation and pistachios give me problems in the stomach as well. I’m looking into more vegetables in my diet less meat but I usually only have chicken, fish, and turkey. I stay away from red meat except for my occasional craving for a burger then I go out. I don’t mind carne asada tacos either from time to time but I rarely eat steak. My numbers are perfect according to Dr. I struggle with my Vitamin D for some reason. I have the ability to become a diabetic due to genes and my diet so I try to stay as healthy and active as I can. I am 45 years old currently grew up on farm fresh food as a small child didn’t have allergies to have of these things until I became an adult. So I have no idea what went wrong only thing I could think of is our dairy and produce are no longer as fresh as they were years ago.
I’m A- and grew up allergic to cold and severe hay fever. Once I hit 40 food allergies kicked in, raw fruit allergy. Most tree fruits especially Asian. Nuts carrots onions celery, foods that hurt my tummy, pork gelatine, tomatoes, Many foods constipated me all my life. I’m only learning now that I have been feed all the wrong foods from birth. I also have been living with rheumatoid arthritis the past 23 years, Seeds are great for me, and spinach. I feel drunk off coffee, I don’t get drunk off voldka, I have a long ways to heal my body, but I’m giving it a go or I am just deteriorating painfully. I’m 53 and hopefully pain free in the years to come. Even water is bloating me these days.
I think the best solution is microbiome.com. There are protocols for detoxing there. You have to start with adrenals then liver and kidney, parasites and heavy metals. I do believe illnesses have everything to do with what parasites we have. I want to do the full protocol. Apparently you just do it and keep working or whatever you do every day. Takes about 6 months. People are reportedly good as rain after that. It is the protocol for Lyme Disease but there is so much of that lately. It seems people have other diseases and end up with Lyme. Won’t hurt to do the protocols and totally detox. Dr. Jay Davidson book on curing Lyme Disease. The protocols come with instructions though. Just do it…can’t hurt.
Hi! I m 48 yo and I found out I m A – at 26 yo. I didn t care at all.Cause nobody told me what that means.I started search the net about rh negative few years ago….no news at all. What should I eat ,cause I m allergic to everyting? Could we be a separate endagered race?Cause what I hear is th RH factor doesn t matter at all.
The allergy part has been proven time and time again.
What do you mean, MIke?
“The allergy part has been proven time and again”?
Myself, my kids and other family members have allergies.

I am A negative blood type in my fifties and over the years have developed more and more problems and intolerances to foods, pollen, dust and some chemicals. I have had to go gluten free but other foods including coffee, oats including gf, bananas, onions, fresh pineapple, garlic, egg yolk or whole egg, cause me issues also and potentially other ingredients which I haven’t been able to pinpoint. A consultant once suggested I probably have a form of lichen planus as I get reactions in my mouth to some foods. I have also become more and more reactive to pollen which for the last couple of years has blighted my life over the months of February to October, starting with tree pollen, I find that I am reacting more to fragrances, flowers like lilies, cleaning chemicals, other things. I have had reaction to dust, smoke, etc for years. I have been put on asthma inhalers due to the reactions. I was told by my GP that I probably have fibromyalgia, diagnosed a few years ago. I find that I have more severe reactions to things when my rhinitis is at its height. My mother seems to have some auto immune tendencies and my son has an auto immune condition. I have been vegetarian for years in my life but was brought up eating meat, and now also eat a small amount of white meat, tuna, occasional salmon but I hate really ‘fishy’ tasting fish and cannot tolerate mackerel as it is too oily. No idea whether further dietary changes would help, but I know that my system seems to be reacting more as I age.
I have shunned meat and seafood since I was a toddler so the blood type diet would not be naturally to my taste as a type 0 neg. No allergies that I am aware of. I eat less and less animal products as I get older.
