Eating for Your Blood Type: A+ & A-

AvatarWritten By


Eating for your blood type means sticking to food that suits your blood, but is it just another fad diet like ketogenic, the Whole30, or Atkins?

The “Eat Right For Your Type” theory was created by Peter J. D’Adamo, a naturopath who put forward the idea that your blood type reacts chemically with food, and you can, therefore, benefit from eating certain food groups.

What Are the Benefits of Following an A Positive Blood Type Diet?

Eating food suited to your blood type may lead to better digestion and improved well-being, such as increased energy, a stronger immune system, and a reduced risk of disease.

D’Adamo suggests that blood type As flourish on a vegetarian diet, which may help them burn fat and lose weight—although this isn’t the primary aim.

It makes sense in theory, but does it work in practice?

Does It Work?

Your blood type certainly matters when it comes to transfusion, and there’s evidence that some blood types are more at risk of disease. For example, individuals with blood group O may have a reduced risk of venous thromboembolism.  

There’s no scientific evidence that eating an A+ blood type diet or an A- blood type diet makes a difference or will improve your health, but anecdotal evidence from followers says it has made them feel better and helped them shed excess pounds.  

There’s no scientific proof these diets work, but the absence of evidence doesn’t necessarily mean they’re ineffective—and the idea has certainly proven popular with the public.

Followers of A+ blood type diet say it has made them feel better and helped them shed excess pounds.

What’s Behind the Blood Group Diet?

The theory is that your blood group reveals the dietary habits of your ancestors.

Type O was the first blood type (although this is a matter for hot debate among researchers).

Type O early humans, identified as far back as the 40,000 BC Cro-Magnons, ate the high animal protein diet of hunter-gatherers, but as they moved into a more settled agrarian society, type A blood evolved to help them digest cultivated crops, fruits, and vegetables.

Rarer B blood types are thought to descend from the ancient nomadic tribes that consumed more dairy from their herds.  

In short, it means that your blood type is better at digesting a certain type of food over others.

What’s Behind the Blood Group Diet?

RELATED: Eating for Your Blood Type—B+ & B-

Type As may have a digestive system with low levels of hydrochloric acid and high intestinal disaccharide digestive enzymes.

This enables them to digest carbohydrates effectively, but they have difficulty digesting and metabolizing animal fats and proteins.

The proteins in food are called lectins. The blood type diet suggests that when our blood mingles with lectins, it creates a chemical reaction. This reaction either benefits or causes difficulties depending on your blood type.

So, type A blood would have no issues with seeds or nut lectins, but it would cause clumping and other issues when combined with animal-based ones.

Type A blood evolved to help them digest cultivated crops, fruits, and vegetables.

I’m A Negative Blood Type—Does That Make a Difference to the Diet?

It doesn’t make a difference whether you’re A positive or A negative.

Positive blood has a protein on the surface of red blood cells known as the Rhesus antigen. If you don’t have this protein, your blood is rhesus negative.

Around 85% of people in the USA have positive blood. Negative is rarer at around 15%—but this doesn’t affect the blood type diet.

You should eat based on whether you are blood type A, O, B, or AB.

What Are The Best Foods for Blood Type A? 

A positive and A negative blood types should eat a predominantly vegetarian diet that’s as fresh and organic as possible.

Foods for A positive blood type diet include:

  • Soy protein like tofu
  • Whole grains
  • Seeds and nuts
  • Fruit (excluding some below)
  • Beans and legumes
  • Dark leafy greens
  • Onions and garlic
  • Salmon and sardines
  • Small amounts of white meat, like chicken and turkey
  • Olive oil

What Are the Best Foods for Blood Type A?

What to Avoid on the Blood Type A Diet

The list of foods that A positive or A negative blood types should avoid is very long and restrictive.

  • Red meat beef, venison, and lamb
  • White meat pork
  • Cow’s milk and cheese
  • Potatoes, sweet potatoes, and yams
  • Vegetables, such as cabbage and pepper
  • Fungi
  • Fruits like tomatoes, oranges, melons, mangoes, and strawberries
  • Fish other than sardines and salmon
  • Oils other than olive oil
  • Refined carbs like white bread and pasta
  • Artificial ingredients

What to Avoid on the Blood Type A Diet

Blood Type A Characteristics

D’Adamo also conducted experiments into characteristics of A+ and A- blood types.

Through questionnaires, he found that Type As thought they were more likely to be sensitive to others, detail-oriented, creative, inventive, and good listeners.

Type As should also avoid loud noises, crowds of people, smoke, extremes of weather, strong smells, lack of sleep, and high-intensity workouts in favor of tai chi, meditation, and swimming.

This is because their stress response pumps out more cortisol, potentially leading to more internalized stress and anxiety than other blood types.

Type As should avoid high-intensity workouts in favor of tai chi, meditation, and swimming.

Is the A Blood Type Diet Risky?

A typical type A blood diet is full of fruit, vegetables, and reduced amounts of meat, sugar, processed foods, and artificial ingredients—so it’s not found to be harmful.

Should I Follow the A Positive Blood Type Diet?

If you want to follow the type A+ or A– diet and you have no specific dietary needs to consider such as diabetes, then you may find it beneficial.

Studies have shown that the A blood type diet can increase your health, but not necessarily due to blood type. A diet based on fruit, vegetables, and whole grains is a healthy diet that’s associated with a lower risk of life-limiting illnesses like diabetes and cardiovascular disease.

However, the A blood type diet is restrictive, and if you’re used to eating meat and dairy, you may struggle to stay on it.

  1. i thought that cabbage was quite good for people with sensitive digestion as it contains glutamine – an amino acid that increases blow flow to the stomach, which in turn helps stabilize the stomach for digestion.
    However above states that cabbage is bad for type A.
    Does anyone know the reason for this?
    I am about to go on a raw cabbage juice 2-day bender!

    Thanks.

    • These are but studies and information that has been compiled about what generally affects different blood types one way or another. Noting that each and every individual, generally speaking, has a unique set or combination of conditions under which their health is most optimal and vibrant at, and that some others can closely, very few perfectly, match, we have to through trial and error find our own optimal and vibrant levels. Looking at the list provided above I can clearly disagree with many of the offered findings. This is because my own individual optimal and vibrant levels clearly differ from those noted above. We allow expert strangers to experiment on us. Why not become acquainted with ourselves and get to know your own individual optimal and vibrant levels. Its fun, and more, its healthy. I do recommend the assistance of one of these expert strangers as they can help you identify your optimal and vibrant levels with your valuable input. Love, Peace

      God bless

      • You are absolutely right.. I am A type and I have found this to be so true. No one size fits all.
        You must be in tuned with your own body. I use The A type diet as a guide line. I am sensitive to wheat so I can not eat Ezekiel bread like the guide line suggests or anything else with wheat in it.
        I can eat sweet potatoes but can not touch white potatoes or other nightshade plants at all for an example.
        So take the time to see what is right for you. You know your body the best. Take care of your
        …..it’s the one you’ve got to live with the rest of your life

      • cabbage is in the cruciferi family not the nightshde. and mushrooms aren`t even a vegetable so they are deffinately not in the nightshade family. however tomatoes are. which goes with the nightshade family is bad for us…. 🙁

        • Go without tomatoes, eggplant, and peppers? I’d give up chocolate first. I don’t believe these cause bad health for me, personally. I’m type A positive and of italian heritage.

          • Hi italian-american:
            I’m glad you mentioned this. I believe regardless of blood type, your heritage also plays a part. Your system has obviously evolved/compensated for nightshade foods. Although i can’t believe you don’t suffer even a little. I, as a Puerto RIcan, have no trouble with natural coconut, ripe mangoes, ripe plantain, ripe bananas, or yams (notice, i specified ‘ripe’, i think this is key as well as preparation). Re nightshades, those suffering from arthrytic pain may want to avoid them all together.

      • a- and none of these things bother me, im quite healthy and happy. livestrong.com also has a story about this, they however end it by saying that all of the claims are scientifically unsubstantiated. its another dr. oz bs diet scam.

        • If none of these things bother you then by all means eat them; however eating for your blood type has been around far longer than Dr Oz. As a person with a gluten intolerance and auto immune thyroiditis I can say from personal experience what you put in your gut has a direct correlation to your health.

      • old post, but what the heck lol…I’m A+ and have zero digestive problems with ANYTHING on the do not eat list….meat, cabbage, wheat, dairy I can devour it like a beast and feel great..

    • I would also have to agree with Luis. As I read through the list of “bad” food items for people with blood type “A”, I found that most of them I have consumed throughout my life in large quantities and represent some of my favorite foods, including lots of red meat (beef, lamb and goat), as well as crustaceans…love shrimp and lobster! Dairy products are something I almost crave, especially milk and cheese so, I’ve always felt it was my body telling me that I required dairy products. I am also athletic which, I feel also allows me to enjoy lots of these foods and provides my body with what it needs.

      Anyway, I find dieting by blood groups to be interesting but in general feel that all people should focus on a balanced diet that includes small quantities of meat, lots of fruits and vegetables, as well as grains, nuts, beans, etc. Most important, eliminate processed food, including sodas, as much as possible from your diet. Finally, find, healthy foods you like to eat and enjoy.

      Cheers,

      Mark

  2. Have you already, or will you talk about type O’s? I am an O blood type and feel so much better eating meat …..and it’s so looked down upon amongst “spiritual” people and such ….have people forgotten that life was sustained by eating animals in many cultures?

  4. Jamie Lynn, after reading this information and getting the book “Eating Right for your blood type” i know not to be down on meat eaters anymore. Knowledge is enlightening.

  7. Good to read about the foods that suit my blood type.It is interesting that a lot of the foods it lists as not good for as A- do not suit me (tend to bother my joints) are the same ones as documented on the list. I have given up nightshade, olives, etc – such a shame as I really love olives, but not reciprocated! I will try to follow the diet more thoroghly and see if it makes me feel more energised.

    • I am A+ and I seem to get along with olives of all types. But wrt crustaceans I get seriously upset and will upchuck the meal at two hours after eating them. I was raised on meat, ice cream, potatoes and suffered from it. I thought there was something wrong with me and suffered panic attacks. Nowadays I do eat raw free range pasture eggs and raw goat milk with no ill effects. I do prefer veggie smoothies with some protein powder and thrive on it. I would say that one can’t but benefit from the list above, but there are exceptions based on your own uniqueness.

      • I am also type A+… Wow I can’t believe that someone else also experiences the same issue with crustaceans as I do… I thought it was strange…exactly 2 hrs after eating I also upchuck 🙁 I guess there is something to be said for this blood type thing! I am also suffer from eating eggs and wheat bread. However, I must admit I love meat and tomatoes and eat them without any problems at all!

  8. As to the condition and health statis of the present population,I belive in the Bible record as the only reliable information availale, involving the existence of the human race today. Mankind started at a very high level of existence at their creation by a intelligent creator God and not by evelution. They started at a very high level of existence and by rejecting the law of a loving creator God, have deteriated down to todays deplorable conition of beings. They are meat eaters or vegetarians by choice and not inheritence, just the same as as Gays and Lesbians are so by choice and not inheritence. I believe this blood typing,for diet is nonsence.

    Percy –

    • You’re entitled to believe whatever. I think you’re way off base wrt science and of your belief that being gay is a choice. You are spewing nonsense, the type that divides and creates hatreds. I pray that you discover that all is good and that everyone is divine, you too, regardless of their sexuality, color, culture, income, IQ, religion, etc. Spread love, not fear. Be love.

    • Pfft! Please! Evolution is Darwinian science, if you’re not an evolutionist believer you’re not the cure pro nature. It’s absolutely necessary that we don’t believe blindly, we believe based on fact or fantasies (depends if you like fantasy), :/ , don’t be let down by the Darwinians, I’m saying you’re wrong. Evolution is science, do you want to believe in something based on non-scientific fantasies, or scientific fact? Don’t be a rebel against science, the evolutionists aren’t your enemy.

    • i see why your post is anonymous, your views are one sided and i believe everyone is entitled to live a life without judgement or fear of persecution. views like yours breed hatred and ignorance. As the planet changes and we terraform it there will be consequences such as eco-systems changing and being wiped out which will ultimately effect human food choice, as we are hunter gatherers human will survive on what ever is available, except for you – if there was no vegetation left as the animals ate it all then it would stand to reason that we should eat the remaining animals to survive. everyone is unique and must eat what is best for them and this is a process of trial and error. being spiritual is one thing, but if a person needs meat to be healthy and vibrant – then the human instinct to survive will be dominant – this does not mean they are sinners, it means they are survivers – you on the other hand wouldnt – and that would be your choice, just dont force your beliefs on others – have respect for everyones beliefs and opinions and choice.

    • Oh Anonymous. If only you could spell, I might take you seriously. We all have the right to believe what we believe – as for choosing to be gay or lesbian…well if we could choose, I think most of us would choose to be straight – it’s easier, people don’t hate you, you can procreate without having to pay gobs for a surrogate and for many other reasons. Our beloved creator creates everyone for Its own purpose and by you sitting there judging anyone as wrong or bad, you are judging “Him” as making mistakes. Deep down we all know Source doesn’t make mistakes. It is pure love, and loves all of Its creations (including the ignorant). Cheers!!

    • umm yes its already being looked in to and has been known for years. alian inteligance came down and interbred with mankind helping us jump evelution. all these religious stories we merly there interpritation of what people could presive alian technology as it was unknown to them.there was the golden years where man walked with the alians, this was the years of hi conciousness, but since then religion,politics,elites,money,material goods, have disconnected us with are higher selves.we all have genetics that dont apear from this planet atall!! people suggest that when you have a – negetive blood type that actualy is apart alian gene cause theres no explenation to how it apeard on are planet. and yes it is out of choice because you choose it doesnt meen its good for you,you could choose to drink petrol if you wanted to.
      are genetics are verry messed up and interbred so knowing who we are and the foods we eat is what makes us live longer, knowing are ancestors helps us as we have apart of them i all of us. aswell as this alian genetics, this alian genetics is what makes us spiritual,what makes us wonder what else there is, and makes us look to the stars.what makes conscousness. so live life and love, doing good things is healthier for the soul than healthy eating. and you should learn by know in this day and age we need to look at science aswell as philosophy and stop seperating the two.

    • I do believe you need to acquire some new concepts…. one very important one is that due to sin we are all broken …. even down to our DNA and hence XXY gender (kleinfelters I think) expressions do exist also called mosaics …so no not all homosexuals are by choice. Yes, I agree that evolution is bunk as a you could not evolve a kidney let alone the whole human body, mind and soul. that does not mean micro evolutionary advantages such as skin colour is not likely. Our creator thought us into existence (quantum stuff).. I believe we are all the virtues when at our best and that disease is an outward expression of our “heart or spiritual issue corruption” . I believe wrong picture memories get stored and thus lower frequencies than LOVE create disease via E = m c squared and quantum rules. For example Jesus simply said to the asking criplle…”get up as I have forgiven your sins”. We are all the virtues at our best so accept no lies from the the liar and thief called the devil who wants to destroy us and our relationship with our heavenly father. Read “The Healing Codes” by Dr. Alex lloyd. Also read your Bible. We are the observer that notices the noticer. Heart in Hebrew means “Image Maker”. If you have a choice between being right and being kind choose kind and remeber even gays are equal as God is no respecter of persons. Gay is like that persons brokenness and we all fall short of the glory of God so judge not lest ye be judged. Thank God for his Son and Grace, Amen!!

  9. The blood type connections to the type of diets we should have has been discredited. I am O- and should be a big meat eater according to the theory, but I am president of Jewish Vegetarians of North America (www.JewishVeg.com) and am thankfully very healthy at 76 years of age on a vegan diet.

    It is essential that there be a major shift to well-balanced vegan diets, because many studies indicate that animal-based agriculture is a major contributor to cllimate change which threatens all of humanity.

    • Richard I too am an O- and I follow the blood type diet but I rarely eat meat or poultry. Generally as an O I do best on a lower carb diet. ( Carbs make me too tired.) Every time I go off the diet for 3 days in a row (ie wheat for 3 days-even a small amount) I am quickly reminded why I stay on the diet.

    • i agree that big business farming,feedlots are very dangerous to everyone.But,when people work with nature as we and others like us do,we do no harm.One needs to be chemically free,and no, I don’t mean organic as it stands in the US and other countries adopting the new organic government standards allowing chemicals to be used.Our animals have free range allowing them to eat naturally.We use animal waste and chemically free grass clippings on our garden and hay.We allow our ponies to eat most of our lawn,while mowing it to keep it even.We even allow spots of Milkweed to grow for the butterflies and bees,and let me tell you,we have lots of both,and even fireflies.I also agree,we need to find what suits us best,as we are all different.Another problem we have is all the chemicals people use on their lawns and gardens.Farmers have to keep very good records of the chemicals they buy,but home owners can pour as chemicals as they want

  11. Your list is helpful but not completely accurate. Generalizations are sometimes detrimental. First of all, there is a secondary bloodtype that people have which strongly influences their food proclivities, secondly, not mentioned, condition, not just constitution is a big factor (ie if someone and most do nowadays) have candida, they should NOT consume molasses or maple syrup or barley malt. Oats are not gluten-free and should be limited. etc.

    I personally disagree with dismissing eggs. And not including the necessity for taking sublingual B12 with the diet above is a dismay.

    There is much truth in what you wrote and it is appreciated, but it is a generalization and sometimes, with someone who will follow it wholeheartedly without additional information, can do harm.

  12. Not sure if everything agrees but this sounds like the work by Peter D’adamo (Eat Right 4 Your Type) which I think makes a lot of sense and I follow. Also work by Robert Young (The PH Miracle) is part of the puzzle. I’m 63 and I do a handstand and full pushups each morning and kick boxing twice a week. I credit these two books and some other stuff with my success. Finding people who are actively challenging our life expectancy is really difficult. Hope they are out there…

  13. I agree somewhat with Percy. As humans we were designed to eat fruits and vegtables and live Forever without any of the health problems we have today but due to our forefather and mother Adam and Eve’s disobeying God and listening instead to the lies told by Satan we now have the problems we have today. No matter what we eat or drink sooner or later we will All succumb to death because of that first sin.

    • I agree to someone else who replied to Percy, i.e. that s/he is spreading hatred, and I’m against the whole childish nonsense about “creation”, the only hatred necessary is Christian philosophy (antinomianism), it’s a necessary evil (not really evil if you think about it), and I say this because s/he’s a rebel, rebels against science, and rebels simply because the nice things that could’ve been believed today didn’t work when Jesus tried them. It’s not Christian beliefs that are the problem, Christianity as a whole is the major problem, I’m an agnostic and I think we cannot know for sure even through science whether it’s evolution or “creation”. I’m against anti-Satanists generally, a Satanist will talk innocent, and will use metaphysics and rationalism, without origin of earth put into it, it’s unknowable to a Satanist, Satan is a punisher, he’s not a bad person, I’ve seen Satan, red beast with horns, He symbolises the love of the rich, the manly, and the eating of meat, he’s trying to make us stop hating and stop acting like wimps.

  15. I’m completely ignorant about my blood type. I need to get fatter (I do this by eating nothing but beef and junk food, sugar, salt and fat), no offence! (none taken, says the vegie). Vegetarianism is half pessimistic, I’ll think about it but I’m as ignorant as a pond about how to be a vegie. I tried it before, the vegetarianism, I couldn’t get it up from the bed :D. I was incredibly shiny, no doubt, and ain’t it the truth! I would like to be a vegan if a vegetarian, I don’t know how to sustain my life on it, however, I want to return, vegie-wise, to the fairy world, the fantasy of strange colours, etc etc. Let’s be realistic, vegetarianism is a fantasy world, me being the witness of fantasies, it would be an honour to be a vegan and stretch my fantasy to a nice place, so if you want to think it’s true, I will do what I don’t believe, because I’m happy without reality, so I want to be a vegetarian on wine, and care for the bullshit.

  16. I don’t know about vegebullshitism, but I like beef, I love junk food, and it has to be bread, meat, wheat etc, filled with fat, sugar, salt, carbohydrates, honey (honey’s not good for you), eggs for cholesterol, tobacco, etc, so as to put on weight, food for my blood type is beef for iron, bread, eggs, for protein and fibre, and it must be white bread, rolled oats, white rice, brown sugar, no cheese, plenty of wine, bacon, hamburgers, hotdogs, sauce and no vegetables, I’m dangerously underweight so my blood needs meat and junk food, doctor’s orders, partially from a cartoon doctor Dr Nick Riviera on “The Simpsons”, and it’s a dream come true, I love meat!!!! 😐

  18. I’m still sympathetic for the vegetarians, I admit I won’t be in the dark forever :(, this means that yes once again I change my mind, I’ll be vegetarian (ovo-lacto-) but not in a long time. This diet is too truly wonderful, and I’m delighted at the exotic flavours, but just because I want to believe crazy things it doesn’t mean I won’t know the truth of vegetarianism to eat for my blood type, but I suppose I will only do it very far in the future for two very good reasons (if not for my blood type) 1. for the ecology, 2. to grow all my organic food, and 3. to stop the cruelty of the animals I suppose. 🙂

  20. Mimo is correct, lets talk about A blood types. I am going to try some of the food suggestions on the list above. Being a colon cancer survivor I have seen how certain foods can effect my body.

  22. Vegetarian means to eat vegetation. Last time I looked a fish didn’t grow out of the ground. I can see the merits of this diet but to say one is to be a vegetarian (I am A blood type and agree, feel better as a vegetarian…who does not eat fish) but this confuses people. Are we to be vegetarians or not? I don’t need my mother in law serving me fish saying it is vegetarian. I finally quit getting her serving me PORK and beans (“just pick it out”.)

  23. This is an amazing article–the foods listed are the ones I like and the ones I should not eat are the ones I don’t like. Now maybe my spouse will quit trying to get me to eat all of those foods

    • I am an A type (they forgot to tell me pos or neg; it’s hard enough just to get US doctors to tell you your type at all). For acid reflux the true and lasting real answer is to lose weight. Period, full stop. But we will all binge on the wrong stuff from time to time if we are human, and gracious when eating with our friends and relatives. In that case, try de-glycerated licorice (chewable) tablets. They work better and faster than absolutely any over the counter poduct I’ve ever ever tried. No lie. The de-glycerate it because licorice root itself will raise blood pressure to some extent. But the best thing is that it is naturally sweet, no need for sugar with licorice.

  25. im A+ and ive tried the diet before. it worked wonders for me, i had just given birth and in 3months i was back to my pre pregnancy weight, however, i have a problem with sticking to the diet because i get to crave meat, all the time!!! and it can be really frustrating!!! please help!

  27. This is really amazing! Ever since I was a child, I’ve hated red meat. My parents did everything they could to make me eat it but I could stand the taste, the smell and even the bare sight of it. The only types of meat I could tolerate were chicken and turkey (breasts only). I would eat all types of sea food though.
    And when it came to veggies and fruits, I loved most of them, except for tomatoes which I found just as revolting as red meat.
    I only recently found that my blood type is A+. So I am thinking that maybe our bodies just “know” what types of food are good for us and what we should avoid. What do you think?
    The only thing I disagree with when it comes to the type A diet is that we should not eat dairy foods. But as someone mentioned in the comments above, maybe our heritage and culture have helped us evolve enough to eat some of the food we were initially not able to digest well. I live in South-East Europe, by the way.

    • Hi Valentina, I have found that this information about different blood types, and recommended diets, is quite accurate. I am B neg, which means I am OK to eat a wide range of plant and animal products. That is a true statement because I do have a very good tolerance for most foods. Basically, nothing I eat becomes an issue. I do not tolerate alcohol very well, however, beyond 2-4 drinks, because I just don’t get much from drinking. BTW, that is a nice picture you posted.

    • Blood type diet dont make sense eat more red meat ok how many docoters would tell you that none to much red meat has be linked to all forms of disease .

    • I happen to know a Valentina, from Eastern Europe, who lives here in California. She is a very successful yoga instructor and dancer. Anyway, back on topic, I agree with what you say. And above also, someone said, you have to test these out for your own individual needs. No one can do it for you, or tell you straightaway what will work for you. I’ve read D’amato’s book years ago, and have some friends who are fairly strict about following the blood type diets. I’m thinking, well, I know, they are a married couple and not the same blood type, so there is some compromise involved there as well. As for me, I love love love the nightshade family, including tomatoes, eggplant and potatoes. (I’m of Irish ancestry; say no more). However, when I was a child, while I loved most raw vegetables, I wouldn’t go near a tomato. As a teenager, I learned to eat most anything. One thing that D’amato says if I’m not mistaken is that peanuts are like a medicine for A types. Now I eat peanut butter (natural) almost every day, and am doing great. It’s about what works for you. I also recommend highly, the insights from the “fit for life diet.” In one of the earlier iterations of this diet, they didn’t want you to eat “cooked” tomatoes, and one should never never eat cooked fruit, or fruit itself combined with anything else, for that matter.

      Wishing you all well, even the religious nuts!

  28. What to do??
    Russian-Canadian
    I’m type A+ and am not fond of what is recommended for this type—-I like and eat everything that is O.
    especially red meats.

  29. Why wasn’t Spirulina,Chorella,Maca root,Beet root,and hemp seeds listed, everyone should at least try these foods to see how it helps.Anyone on a vegetarian diet should try these foods.I use these in a powder form and used as a drink,they have helped me and others in a big way

  31. The correlation between science and Christianity is the conclusion that God does exist and is the creator of all things. By inducement of satan our ancestors made a wrong choice with cumulative negative consequences for us and future generations.

    If believers of satan want to revel and rejoice in the mistakes of our common ancestry, it is by choice and by all means they would live to reap the consequences. Christianity spreads love and recommends reconciliation of man and his maker, so that we can all return to our high state of existence which was before, a state of perfect health and wellbeing.

    • I believe this whole thing is about food, not God. I am a believer but am trying to educate myself for my health. I have cut out most of the foods disclosed in this article in the past and it has helped. So please if you don’t care about the issue at hand then please keep your opinions to yourself.

  33. Hello, I’ve just ordered a book on eating right for your blood type, I have also just found out that I am A positive. I’m very interested in all that this has to offer and am excited to start. Any suggestions or links would be more than greatly appreciated.

    Thank you 🙂

  34. Since I was young,I was meeting digestive problem whenever I ate corn,potatoes,apple,orange,..until I gave up completely to eat them.I was surprised when I read this section and found out every food that was making me sick in my stomach is not of my blood type.so,these advice are right

  35. Thanks so much for the education given to me. I am blood group and with this education, l am sure my health will be improved. Thank you once again.

  36. THanks so much for the education given me. I am blood group A and with this education, l am sure my health will be improved for a longer life. Once again l say thank you.

  37. Well i found this rather interesting and i will give this a try as i have tried many unsuccessful way of life diets but the most disappointing thing is NO RED MEAT (sniff sniff)

    • Red meat is ok for o+’s, but not to excess. I have canned, baked beans when I eat red meats, it binds up the cholesterol and other bad fats so they are not absorbed as well. I also follow The Move That Waist diet.

  40. suffered for years with acid reflux, and untill i started this diet, i was a meat and two veg man and yorkshire puddings and gravy and a pudding for afters. being type A we are prone to acid reflux.

    the diet has helped me no end and i will not eat meat like i used too, im not strict with the full diet, but cut out most things especially meat and spuds. if i eat meat it makes me ill and i get acid reflux again so i now stay away from meat, got a craving for meat, i eat fish or poultry instead.

    a tip to help is dont eat food and have a drink, leave at least an hour inbetween food and drinks, that way you dont water down the acids in your stomach, they do the job they are ment to. love and light and enjoy the diet

  41. As a blood A patient ,and discovering these facts about all the groups i should once again say that ignorrancy is really a desease as well as illitracy.Let us teach those who dont know .People are dieing why?Because they dont know.

  43. I am fight ulcer now i mean very seriously just after realising am an A.If i was aware i wouldnt have been taking in some foods especially drinks .but now that i know it should be a lesson to all the a A-

  45. Very interesting article. Highly informative as a guide. Some adjustments could be required though. Fully agree to the statement regarding ‘cortisol’. Thanks for sharing

  46. Thanks for the information. I have Kidney disease and really watch what I eat. I am A-pos and found this article interesting. The comments however really get off subject.. This is one study – If you want more info do more searching. Don’t bring the Bible in where it doesn’t belong (yes I’m a Christian, but we are talking diet here not creation). Farming is not the issue here either it is the type of food we eat. These people are trying to share knowledge with us and instead of accepting it for what it is some of you really got carried away.

  47. Unbelievable!! its like the person knows me! im 38 and have worked out for myself to avoid the foods that have been listed here. My personality is an exact fit and i avoid harsh weather, noise, crowds and negative people, scary films leave me feeling exhausted and lack of sleep (my no 1 problem due to a child that never sleeps) leaves me constantly stressed and irritable.
    Ill follow the rules on this even more. Im convinced this is the best diet ive ever read. Thanks 🙂

  48. This article is so poorly written it hurts. It’s hackneyed, disorganized, and full of clichés. Further, your information conflicts with itself. For example, apparently A-types are supposed to eat olive oil, but avoid olives.

  49. I, be live you are all right about how to watch what you eat, and yes eat for your blood type can help people make some right choices for them salves. that’s why its nice to have information out there that can help people like us who are trying to keep healthy for our family and friends.

    • Yeah, meat’s delicious, but you save a lot of money on groceries if you limit your intake. Myself, I treat meat as they do in poorer countries, among the common folk, meat is used sparingly, and more as a flavor than a feature. Only in the West, esp N. America, Argentina, Columbia, and some African countries do people gorge especially on huge slabs of red colored flesh.

  52. oops, yes, and Australians famously love their red meat. What of the germanics and to some estent the slavs with all that nitrate/nitrite (?) laced sausage and such. Woohoo, don’t know how they’ve gotten by with that! But my parents’ generation always kept a can of bacon grease on the back of the stove to cook with, never ever took a statin drug and lived fairly healthily into their nineties. Is is all a bunch of crap? We may never know.

  53. Very interesting article…had never heard dietary and lifestyle recommendations based on blood type! The majority of the recommendations seem legitimate except for the protein reduction as I have been classified as a protein metabolic type.

    • you can eat chicken, turkey, fish burgers, turkey hotdogs, turkey bacon. And red meat if you take a digestive enzyme or at least some lemon water first. If you want to live, eat peanuts daily if your able to eat peanuts, stop dairy, and opt for rice over bread more often. If you want pizza have mozzarella pizza.

  55. I am a type O+ blood type and I find that following the “Move That Waist” weight loss works great for me.

    Obviously, I am a big believer in a wheat-free life. My life changing experience of melting away my “wheat belly” in 90 days still gives me goose bumps that such a simple solution existed for losing the excess weight and reaching normal and below lab results along with dropping the weight.

    After doing my research on wheat, losing the weight is important, but the many components of modern wheat impair human health in so many other varied ways. Multi-grain breads; this is junk food masquerading in a healthy disguise. Check the ingredient list to make sure whole wheat is the first, and main, ingredient—otherwise, you’re just getting a few grains mixed into regular white bread. Better yet, forgo the bread and enjoy straight-up barley, brown rice, quinoa, or steel-cut oats.

    Put all of these pieces together, and you’ve got a heck of a health-distorting foodstuff. Wheat is the perfect storm capable of generating in humans undesirable health effects that no other plant or food can match. And it enjoys all the official endorsements, all urging us to eat more “healthy whole grains.”

    I choose a world of a slender, healthy, non-wheat-consuming lifestyle, more resource efficient than a world of overweight, high-calorie-consuming, unhealthy lifestyle which relies on the medical system, medications, and unwanted procedures for maintaining a healthy body.

    Wouldn’t it be great if we as Americans could put to use, scientifically proven methods of healing instead of a lifetime of taking expensive prescription drugs? The healthcare bill in this country would certainly plummet!

  57. Thank u 4 educating people like me, I’m A+ & these are innate in me but i don’t like Okra bcus i do vomit whenever i eats them.
    I also suport ur writing DONA

  58. I just read your blog and am very impressed at how informed you are and your attention to detail. I was also impressed that you clued in some charisma to your blog instead of the same old robotic writing I see from everyone else. We would love to have you write us a WebWatcher article sometime.

  59. I read everything about this diet and have to wonder what I CAN eat. Almost everything that I enjoy is off limits because I am A positive. I love white milk, potatoes, tropical fruits and seafood. I don’t like tofu but do highly enjoy veggies. It kind of makes me discouraged when I think of all the foods I would have to give up.

    • you don’t have to eat tofu, you can eat potatoes if you really want. Just make sure to eat peanuts if you can so your immune system will be able to identify cancer like it should, and never touch cow dairy again. If you get sick, cut out wheat and put a little soy milk in your diet for a short time.

  61. I am RH A- i am vitamin d and B12 deficient. Milk upsets my stomach and i don’t like red meats oranges give me acid reflux i had to have 64 rohgam shots with my first child but none with my second. I do have minor health issues as well.

  62. This is a very misleading article. Your diet has nothing to do with your blood type. This diet outline is a basic, good diet for anyone, unless you have other things like diabetes interfering with your health. Instead of consulting articles like this for dietary information, just go talk to a Physician. Seriously.

  63. This makes sense, even more so now when I’m getting older (middle aged) and my body says “NO!” to me ignoring problems any longer. I have problems with wheat and milk protein, I quit all alcohol 22 yrs ago, it just took too long to recover and I got awful headaches from very little. I have a very sensitive gut system and have always had it. i always avoided red meats (instinct?) but love seafood, but react to my favorite seafood shrimp. I eat white meats and limit the amounts. can also mention too much sodium is bad. Bummer, I’m not a veggie person, but as time passes I am forced to think about what I eat, and this description matches my findings.

  68. I’m A-,and yes, meat never made me feel good at all. Stopped eating meat years ago. A little fish is ok, but mostly veggies, and some fruits. It’s really trial and error when it comes to eating!

  69. I’m an A- and mustard and onions set off my acid reflux really bad. I’m also extremely anemic and have low blood volume and pressure so i need red meats like liver, heart or kidney just to stay alive or i’ll be on heavy iron medications. It kinda sucks. As the one person who commented said some of these things i need to avoid i love. Like pistacchios i’m currently eating them while pregnant due to the high B6 levels of them but here it says i should avoid them.

    • im wondering if you had an rh posative child, if your reacting to the rhesuses monkey gene, that happened to me trying to have my first rh posative bb. My blood stayed slightly low for a few years after. Bb’s cells are still circulating in there too so hopping after a decade it will go back to normal.

  71. This is absolutely 100% opposite of what I’m supposed to eat. If I eat carbs, good or bad, a gain 10 pounds a month. If I stick to a lean meat (grilled or baked) diet with few carbs, I lose 10 pounds a month. I have no issues with milk or dairy products and eggs always soothe my stomach when I feel sick. Not to mention the fact if I ate what they recommended, I would die of starvation. Eighty percent of what they suggested I can’t eat or it kicks in my gag reflexes.

  72. Typical, all the things allowed I hate and all the things not allowed I love. And I have ALWAYS been told that tomatoes are excellent for helping prevent cancer. I would NEVER give up tomatoes, cashews, or dairy.

  73. This couldn’t be more spot on for me! Ive tried lots of different eating types from paleo to vegan, and eating for my blood type makes the most sense. It resonates 100% with how i feel, emotionally, physically while eating for my blood type. And, absolutely validates how certain foods from the “avoid” list negatively affect me. I’m so greatful to Dr D’Adamo and Dr. Lam for all their time, studies and information regarding this way of eating.
