What to Eat According to Your Blood Type

Should your blood type tell you what to eat?

The idea behind the blood type food chart comes from Paul D’Adamo, a naturopathic doctor.

Each blood group has a unique chemistry, and each food contains a type of protein called lectins. When these two interact, lectins can stick to your red blood cells and cause problems if they clash with a specific blood type.

When lectins bind to the antigen of your blood type, your red blood cells almost clump together.

When that happens, it can cause tiredness, headaches, skin issues, and problems with your gut, and it may also trigger an autoimmune response in your body.

Most of the time, these lectins aren’t harmful. Normally, your immune system protects you from lectins and removes about 95% of them. But the remaining 5% do end up in your bloodstream. And eating according to your blood type is what can help you manage those 5%. This way you can improve your digestion, your energy levels, and some chronic conditions.

So let’s get started:

Type O

Also called the original omnivore, people with type O blood are considered the original hunter-gatherers. Their ancestors consumed a diet rich in animal proteins and not so many grains and dairy products.

That’s why it’s best if you have this blood type to have a diet that consists of high-protein foods, similar to that of your ancestors. In general, people who are type O tend to have stomach issues, and it’s best to keep a well-balanced gut. If you are type O or you struggle with gut problems, this is a powerful remedy you can try.

Foods to EatWhat to Avoid
lean meats – lamb, beef, poultrydairy products, especially milk and cheese
fish rich in omega-3 fatty acids (salmon and mackerel)grains: wheat and barley
vegetables like kale, spinach, and broccolilegumes: especially peanuts and lentils
fruits like berries, plums, or figs highly processed foods and sugar

Type A

The agrarian, people who are type A are believed to have descended from agrarian ancestors who mostly cultivated grains. That’s why it’s recommended to have a diet rich in plant-based foods and to avoid animal products as much as possible.

If you’re type A, you should pay close attention to your immune system. That’s the most vulnerable thing. Also, there’s a higher risk of developing thyroid problems, especially hypothyroidism. I happen to be type A, and I have an autoimmune condition. While searching for the natural alternative to the fistful of pills the doctors were prescribing me, I discovered this mushroom blend. It’s a dual extraction tincture made of lion’s mane, reishi, and turkey tail that I take every day, and not only does it help me modulate and regulate my immune system but I don’t have any side effects. These three mushrooms are called “adaptogens” and they can balance a variety of issues in the body, ranging from autoimmune conditions to protecting the body from the effects of stress.

Foods to EatWhat to Avoid
fresh fruits and veggiesred meat and poultry
whole grains, especially quinoa, brown rice, and oatsdairy products, except fermented things (like yogurt)
plant-based proteins like tofu and tempehrefined sugar
nuts and seeds, including almonds, flaxseed, and walnuts

Type B

This one is sometimes called the balanced omnivore. People with type B blood evolved in regions where there was a balance between agriculture and raising animals. That’s why the best thing to do if you have type B is to find the perfect balance between animal and plant foods.
Some of the most common health issues for this blood type are all sorts of pulmonary problems. You’d be amazed how fast a common cold can turn into dangerous pneumonia. And they’re also prone to developing COPD.

To keep a cold from developing into something worse, here is a natural fever breaker. You only need three ingredients.

  • 3 tablespoons of flour (I suggest you use organic and unbleached)
  • 2 tablespoons of dried mustard powder
  • 2 tablespoons of water

You’ll also need a bowl and a Ziplock bag.


  1. Add the flour and mustard powder to the bowl.
  2. Then slowly add the water and stir until you get a paste. It should have the consistency of pancake batter. You may need to add some more water.
  3. Transfer the paste into a Ziplock bag.What to Eat According to Your Blood Type- put it in a ziplock bag
Directions for Use:

Lie down, and place the Ziplock bag on your chest or back. Make sure the paste is not directly applied to your skin. Cover yourself with blankets.

After a few minutes, you should start sweating profusely. If it becomes too hot, switch sides to place the bag on your chest or back.

Try not to leave it on for more than 10 minutes.

This is a recipe I recently tested, and it worked wonders. I discovered it in The Lost Remedies Academy. This recipe proves you don’t need much to make powerful natural remedies. Plus, everything you’ll find in this academy is presented in video form, so it’s easy to follow along.

Foods to EatWhat to Avoid
lean meats like venison or rabbitcorn, lentils, and peanuts
different types of fish: cod, halibut, and troutwheat products, especially bread and pasta
dairy products such as yogurt, cheese, and goat milksugar
fruits and vegetables to help keep balance

Type AB

Also known as the enigma, they are the rarest and newest in terms of human evolution. And just like the name suggests, the best approach is a combination of the foods recommended for types A and type B.

Just as with food, this blood type has a combination of health issues you can get with types A and B. However, there is a higher chance of developing brain and memory issues. There’s a recent study that shows type AB people have an 82% higher chance of experiencing memory loss. So if you want to improve your memory, mood, and cognitive performance overall, you should try this powerful brain bundle.

You can also try an easy herbal infusion you can make with only two ingredients you probably already have in your pantry.

You’ll need one teaspoon of chopped dried mint, one teaspoon of chopped dried rosemary, and one cup of water. Rosemary is wonderful for cognitive health and boosting brain memory, and the addition of mint is uplifting and promotes focus and energy as well.

Boil the water, add the herbs, and let it steep for at least 20 minutes.What to Eat According to Your Blood Type- add the herbs and steep

Strain it and drink one cup a day.

You can make it fresh each day or make a big batch and store it in the fridge in mason jars for up to seven days.

It’s obvious food influences your overall health. Now that you know all these things about the relationship between your blood type and what you eat, you can make some small changes in your diet that can totally influence your health.

Wait. Put it in a SEALED bag and then on your chest?

I’m with you except for your promotion of evolution. God created me with type O and I can’t digest protein very well. I also react to wheat, even wheat seeds that are found in gluten-free supplements.

Evolution is part of this divine universe! If we don’t evolve the universe can’t expand so we are always evolving and expanding. That’s how our benevolent creator set it up!

Sure feel sorry for you, Martha, but you’re free to believe as you choose, as everyone else is free to believe as they choose.

Thankyou for that simple response to those misguided souls . I will use that when I next come up against sad blinkered zealous bigotary promoted by the god fearers .

To ‘fear’ God means to revere Him for being the creator and sustainer of all that was created by Him which is positively everything. But don’t worry, God has made a contingency for unbelievers. He loves you as much as He does believers. He has given you the chance to enlighten yourself by delving into His word, Bible, for the real truth about this life but more importantly about the next life, where we will live with Him in Heaven. I’m sorry that you think you came from green slime because you deserve to know the truth. Jesus is the Truth. After all, He died to give everyone the hope of Salvation and Grace to lead us all to the Cross for forgiveness. He is waiting for you but it has to be your choice.

Total BS on evolution. If you think humans are turning into something on a higher plane, you are living in a sealed cave and your oxygen level is almost depleted.

Beth , besides the particular blood type advice I think your symptoms could be helped by searching more about the Lectins mentioned in the article .
(The Plant Paradox)
There are specific foods to avoid to reduce these Nasties .
By any chance do you eat tomatoes, cucumbers , squash, peanuts , normal potatoes or out of season fruit plus other high lectin foods .
Try eliminating all of these and see what happens .
I hope I have answered your prayers .

Thank you for this refresher course on the blood types. What about O Negative? Anything I should be doing in addition to being type O?

Dr.D’Adamohas a full line of books and info on his website.

I also have this question…

The article about and books promoting the propaganda of the type of foods to be eaten by blood type have given me a good chuckle after my first experience with trying it out. Nothing is ever said about what happens when one has a parent with one blood type and the other parent with a different blood type. Somehow genetics are totally left out of this narrow minded fantasy. Very thankful to have the common sense to have identified the diet my body does the best with and it is FAR from the recommendations of the blood type diet. Were I to eat per my blood type I would have constant digestive, cognitive and neurological problems, including irregular heartbeats, etc., and there’s no way I’m going to follow someone’s nightmare idea when it’s most certainly bad for me. When the stupidity of blood type diets came to my attention some 40 years or so ago, I was stupid enough to think it was a good idea. Within two weeks I was a horrific mess and hourly getting worse with irregular heartbeats drastically limiting my ability to do very much. Sure didn’t take me long to go back to the diet I was accustomed to and magically things straightened out. Every body is an individual organism and there are no guaranteed answers for everyone. People need to use common sense including the idiots who have nightmares and publish them trying to make their mint. Sad truth is the general public is stupid they fall for anything written down, making idiotic assumptions it is truth and a magic answer, completely omitting common sense. I’d have died in my very early 20’s if I’d been stupid enough to believe this nightmare enough to continue with it. For some this idea may work, but for many it doesn’t at all.

Wow, your comments were useful, but did you have to be so self-righteous and uppity about it? By your own admission, you followed this diet yourself, so you could at least be less judgmental. Not because you are now enlightened is it OK for you to now get on your high horse. Calling people stupid and fools is uncalled for.

Some interesting personal observations there and good you discovered what is best for you .
Personally it was spot on for me and my current diet .
I was not sure about the little dig about Mint .
I think any person who does not feel the aroma of fresh crushed mint leaves when inhaled is up lifting and joyous is missing out on something .
The Mint family has a variety of plants such as
Bee Balm (mellissa officianalis) I believe has been known for many centuries to be a powerful brain tonic (drug ).
Take the origins of these sayings for instance regards over users of Bee Balm (from the 1500’s)
which then transfered to ‘The mad hatter’
There are others I just cant recall , I need some tea.

Ah I re-read your mint comment about Mint and perhaps people who are having nightmares could have over indulged .
Mint really is a powerful Brain Drug and needs to taken in moderation.
It is sold commercially with many sweetened candy for instance .
Stevia is also a mint perhaps this now common natural sweetener is messing with some suseptable peoples minds.
Just some morning thoughts here thrown out to the crowd , stay well people.

…such an aggressive reply without a good reason…yes, people need to have a common sense, and same time be a courageous enough to play with a new and unknown, otherwise there wouldn’t be a progress ….I can’t imagine, that someone could be in a health crisis from using Blood group diet (BGD)…
when I red a first time about BGD,I thought such a nonsense…. but I red it a second time, and it make a really sense…. I implemented BGD A to my life, and it improves my health dramatically….these days I am not so strict, yet I follow most of recommendations automatically … as a RN, I also did my personal study in a hospital, observing who has which diagnoses and I did see, how different peoples health is, according BG types. BGD definitely is my “go to “is I need improvement in my health .

What if your blood type is RH O- (o negative)?

Hi JoAnn,

Thank you for your interest in this article!

The Rh factor does not influence the diet, so you can follow the recommendations presented for Type O.

Many blessings and good health!

I am O-, both my parents and siblings are 0-. I do have a lot of digestive issues except when I eat meat. I have recently been test to have an intolerance to any milk or cheese from any mammal. So for me this eating according to your blood type is right on the money. I just wish I read this sooner.

Hi Melanie,

Thank you for your comment!
We’re happy to hear that this article is helpful to you!

Many blessings and good health!

I have to disagree somewhat with regard to type
A. I have allergies to tofu, walnuts, melons, wheat etc. I find that I feel continually hungry until I eat meat.

Hi Denise,

Thank you for sharing that with us!

Certainly, every person’s organism is different, and these are only some general recommendations. If you are allergic to those foods, do not include them in your diet by any means.

Many blessings and good health

Hi, Thank you for all your knowledge you’ve given me a lot of health benefits. I was just wondering does A positive blood type follow A or is there another diet for Apositive?

Hi Julianne,

I make tinctures but am not familiar with a double tincture and I have never tinctured mushrooms. Can you briefly explain the process.

Hi Mary,

Thank you for your question.

You may use this article’s recipe instructions as a general guideline:

I have been following the B diet for 6 months. Having being diagnosed with GERD and low blood iron from a sliding hiatus hernia, its enabled a great turnaround. Some chronic symptoms ended within days. I had been vegetarian for 45 years. It turned out to be the worst diet due to the amount of high legumes – most of which are on the AVOID list for Bs. Ive now intrduced fish. The Blood Type Diet has been miraculous!

Absolute bullshit. I (type A) cannot eat soy or grains because I have Coeliac disease. Meat is the only safe food for me. What a useless article.

My husband and I have been following the blood type diet for almost 30 years. He is O type and I am AB – quite a challenge when living in the same household, but we have worked it out to suite both of our needs. Our one son is B and the other AB.
We follow the recommendations loosely as it fits into our lifestyle (life is short!) and more strictly when we have a health issue to deal with.

O blood type is best with red meat according to Dr. D’Adamo. It has totally proven out with my husband. Not only does he crave red meat, but he suffers without it. Pasta and wheat bog him down.

We ate a strict vegetarian diet for over 10 years, until both of us adopted our O and AB diets. The benefits were most obvious with my husband, with increased energy and general good health. I had no problem with eating mostly turkey and lamb for meat, but I don’t crave meat in general, which fits my AB profile.

There are people who are exceptions to this this diet being beneficial of them, but over the years, I have found that most people gravitate to the foods that are beneficial to their blood type, even when they are not familiar with it. That’s the best part of this diet.

Does this apply to “O negative” blood types?

Thank you, I enjoy reading about all your remedies. It has helped me tremendously, my mother too! We purchase your books and products. Many blessing to you!
