Some of the concepts in this book lack full scientific support. However, the diet might still make many people feel better and achieve a higher level of health. These two aspects are not mutually exclusive.

Reasons the claims about the scientific merit of the food lists for each blood type are unconvincing to me include:

1. I've read detailed explanations showing the 'Blood Type' books are based on sketchy science. Some theory makes sense, but there are holes in both the theory and how the food lists were compiled. This information comes from respected health and nutrition authors, not those who deny non-mainstream ideas.

2. Even if blood type matters for diet, biochemical individuality means there would be as many differences as similarities in what people of the same blood type eat.

3. Family members with the same blood type often do well on different diets, illustrating the above principle and that different diets suit us at different times due to bodily changes.

4. The diet is rarely discussed favorably in chat groups. Most people say it didn't help and was a waste of time.

The Body Ecology Diet book explains that the blood type diet books offer valuable clues but should be considered a developing theory. It has several shortcomings, such as not being adapted for those with certain issues, not emphasizing cultured foods, lacking a protein guide for some vegetarians, ignoring food combining, wrongly advising against apple cider vinegar, not discussing food preparation methods, recommending yeast-feeding foods, and more.

However, the blood type diet book can still potentially improve health because it advises cutting out junk food, choosing higher quality organic foods, increasing vegetable intake, cutting out common allergens like dairy, grains, and legumes, and helping with weight loss for many.

Overall, while the book has some good diet tips, it promotes a flawed theory. There are easier ways to get healthy and lose weight. You might start with a simple nutrition book or try the Paleo diet if you suspect issues with grains and legumes. If you think you have food allergies, you may want to have testing done and look into related issues. To learn about fats, you can read specific books. In conclusion, eat real food, consider hidden allergies, and find the diet that suits you as an individual.

I'm not entirely certain that it's entirely fair for me to pen a review of this book considering that I only perused the sections that were relevant to my specific blood type. My particular copy of this book is a whopping 21 years old. As a result, it's inevitable that some of the advice it contains, like avoiding coconut oil due to its relatively high fat content, has become somewhat outdated. After all, the field of nutrition is kind of like a bit of a crapshoot. The advice can vary so drastically from one diet plan to the next.

I do find it rather interesting that a significant number of naturopaths seem to subscribe to this particular way of eating, especially when bio-individuality is placed right at the forefront of their nutritional approach. However, I must admit that the section dedicated to my blood type did seem to have some applicability to my own personal situation. The general recommendations to increase vegetable intake, avoid sugar, limit inflammatory foods, manage stress effectively, and engage in regular exercise are all undeniably good pieces of advice.

I fully intend to revisit this book in a month or two's time and provide an update on how this dietary approach is working out for me. For the time being, I'm awarding it 3 stars.

I don't think it is fair for me to state that I read this book because in reality, I merely skimmed through it. A coworker recommended this book approximately two years ago. I promptly purchased it and even went to the doctor to determine my blood type. Shortly afterwards, the same coworker mentioned that her doctor had told her that the book was junk science. Since I never disclosed to my doctor the reason for my need to know my blood type, I can't wholeheartedly agree.

I will admit that there is no way I am restricting myself to the foods listed in this book for people with my blood type. However, I will note that some of the foods suggested for those with my blood type are ones that I already consume and have a craving for. Is it science or just a coincidence? I'm not sure.

The nice thing about this book is that unless you are truly interested in the subject and history of blood types, you can simply read about yours and then put the book aside. That's precisely what I did, which is why I won't claim to have read it cover to cover. I only read the parts that were relevant to me.

Overall, I didn't find it to be of any real benefit. In fact, I found it to be excruciatingly dull.

The idea that your blood type determines what you should eat and how you should exercise is truly compelling. I borrowed this concept from a friend.

Of course, I began by skimming through the information related to my own blood type. It felt much like reading a horoscope in a Sunday paper. There were indeed some aspects that seemed to fit, but there were also others that were completely contrary to my personal experience. I couldn't help but laugh out loud when I read that certain blood types are prone to heart disease and cancer! Oh really? Those are only the top two killers in the US. Thanks a lot for letting me know! :) The lack of actual research or study citations becomes very obvious in light of so many'scientific' assertions. Although there are numerous anecdotal case studies, it further gives the impression that this book is more about the author (and his desire to break new ground and/or recruit followers) rather than the actual content of the book.

And yet, I couldn't resist the appeal of the idea. Wishing to take my investigation a step further, I called my mom, who is the resident medical expert in our family. We discussed our family history and how it aligned with D'Adamo's theories. Our conclusions were pretty much the same as mine previously. The categories of blood type, as presented, simply failed to offer any meaningful insight into our family health history.

Finally, I read a few reviews on Goodreads and looked up the idea on the web by googling "Blood Type Diet". It appears that others had similar issues with Dr. D'Adamo's theories as I did. There is simply no research to support his ideas. In the end, the types he describes are so general that those who are willing to believe will quickly identify with his writing and ignore all that doesn't fit.

This book is not recommended at all. Well, I guess if you are studying mass hysteria, the development of cult followings, or something similar, D'Adamo's book might be of some interest to you.

An interesting approach to diet and lifestyle has been presented, yet it seems a bit too generalized to be truly effective. I initially thought this would serve as a helpful tool for me to tweak my eating habits. However, upon further reading, it comes across more like a "fad diet" book.

To be fair, there are a few effective arguments and some good advice to be found within its pages. Nevertheless, it is marred by an excessive amount of pseudo-jargon, which ultimately renders it less useful.

Overall, this book simply didn't resonate with me. It failed to provide the practical and personalized guidance that I was seeking to make meaningful changes to my diet and lifestyle. I'm left feeling disappointed and still in search of a more reliable resource.

I borrowed this book from my Mom years ago.

I initially set it aside, assuming it would be overly bio-scientific and not to my taste.

However, I was completely wrong. It was written in a way that the average person could easily understand.

This book turned out to be a very interesting read. It detailed the evolution of blood types and how they form the basis of human diets today.

I focused on the O types since that's my own blood type.

My success with this nutrition plan was achieved in an unexpected way. Over the past couple of years, in my pursuit of a healthier life, I experimented with my diet.

Through trial and error, I gradually moved towards the "Type O diet" even before reading this book.

I'm not entirely sure if this would work for everyone.

However, my own success through trial and error does support the book's theories. Interestingly, many of the characteristics also held true for my close family members.

What I find particularly interesting when looking at the comments of other "readers" who gave it a low rating is that I can't tell if any of them actually tried the nutrition plan and failed, or even read the book at all.

Those who did comment simply dismissed it as "theory" that at best makes for interesting reading. I'm amazed at how people are so willing to take unnatural, synthetic drugs because a doctor says so, even though that doctor may not have actually studied the drug.

Compare that to someone who has studied a field for years, tested his theory on real people, and found it to work.

Oh, and by the way, he's suggesting foods that the human body has been known to tolerate for thousands of years!

I guess, like everything else, people want a quick fix rather than the best one.

As I said, I'm not convinced this will work for everyone. But I do believe that since it's natural, the worst that can happen is you waste a bit of money and some time and energy.

After reading this book, I am truly astounded by how dangerous I perceive it to be.

If there were an option for a negative rating, I would not hesitate to select it without a second thought.

The central concept of this book is that individuals of certain blood types should adhere strictly to a specific set of foods and completely eliminate other foods from their diets. However, I can clearly identify a plethora of issues with this so-called theory. In fact, that's precisely what it is - just a theory.

Can anyone tell me when and where in the entire history of life there has been any legitimate proof or evidence to support this claim?

I have learned that some of my close friends have subjected their children to this type of absurd diet. Consequently, I reached out to my children's pediatrician and sought his professional opinion. He concurred that this book is nothing but a load of nonsense and is, in fact, extremely dangerous to attempt on both children and adults alike.

Do not waste your precious time on this. I seriously doubt whether the author of this book obtained his degree from a legitimate institution or if it was perhaps some sort of joke, like getting it from a Cracker Jack box.

Well...

I finally managed to finish reading this book simply because the library wouldn't allow me to keep it any longer. I initially began reading it as I had heard a plethora of diverse opinions regarding the Blood Type Diet and was eager to gain a deeper understanding. While perusing this book, I indeed made an effort to steer clear of foods that were purportedly harmful to my blood type. Given that I already felt quite healthy prior to this diet, I didn't notice any remarkable benefits.

This January, a fresh study emerged, revealing that there is absolutely no scientific evidence to support the Blood Type Diet. The only thing it found was that the diets recommended for different blood types are generally quite healthy and could benefit an individual of any blood type. Anyhow, now I have reverted to my regular diet and am relishing tomatoes, avocados, chicken, peanuts, some wheat, etc. (all those forbidden delights!) in moderation.

Generally speaking, I was quite fond of the concept of the Blood Type Diet, and some of the points put forward by the author seemed rather reasonable. Nevertheless, in my view, the book is rather outdated and lacks solid proof. Most of the conclusions are derived from observational studies (which are rather subjective) and generalizations (such as having a theory and attempting to apply it everywhere) rather than objective scientific evidence. Since I possess a certain scientific background, the book appears a bit repetitive, and some explanations are overly simplified. However, it might prove beneficial for someone without a scientific background.

All in all, I believe that the Blood Type Diet theory is not entirely without merit, but I do not concur with the author's assertion that EVERYTHING about us is determined by our blood type and that living, eating, and exercising in accordance with our blood type is the only viable approach.

I firmly believe that this particular book encompassed an abundance of highly useful information with regard to our health.

It seemed to hold the key to understanding many aspects of maintaining a healthy lifestyle. However, the problem was that there was an overwhelming amount of technical information presented within its pages.

This excessive technical jargon and detailed explanations had the effect of clouding my head and leaving me in a state of confusion.

It was truly a case of information overload, where my mind struggled to process and make sense of all the data being thrown at me.

Despite the potential value of the information, the way it was presented made it difficult for me to fully appreciate and utilize it.

I found myself longing for a more simplified and accessible approach to the subject matter.

This book emerged during a conversation with Kathleen before she journeyed east. A relative of hers had reaped significant benefits from adhering to some counterintuitive advice from it, which was precisely the kind of thing that piqued our interest for our style of casual discussion. Anyway, I thought the premise sounded too strange to overlook, so I borrowed it from the library.

Basically, D’Adamo contends that your blood type determines or at least has a primary influence on your metabolism and your ability to digest specific foods, and then proceeds with a rather detailed breakdown of how you should eat. He supports this structure with his personal clinical experience, presented as a series of anecdotes scattered throughout the text, and some extremely dubious anthropology that reminds me of nothing more than the Jakeskin from Templar, AZ. In terms of references to peer-reviewed studies demonstrating the mechanisms he postulates, well, there aren't many. (And he lets slip once or twice that he advocates homeopathy. Red flag!) So I was skeptical. But to be honest, I found myself desiring to believe what he was saying. Mostly because of this sense that ABO blood types must be good for something other than transfusion complications and manga character taxonomy. Really, why shouldn't the very composition of your humors affect your digestion? And this, friends, is probably why the book managed to become such a big hit.

Anyway, as I said, I checked it out. Apparently, as a Type O (The mighty hunter/gatherer! Roaming the African Plains in search of MEAT! Never mind that most of the protein in the appropriator diet seems to have come from bugs), I should be eating approximately the diet that my Type A (The vegetarian farmer! GRAAAAIIIIINNNZZZZ!) sister eats, while she in turn ought to be craving the pseudo-vegetarian diet that comes naturally to me. Despite the reductionism and lack of instinctiveness, I still couldn't, in the end, see any reason to adopt the diet he advocates. It's all just his word, with nothing concrete to back it up, and the situation looks even worse when you google “blood type diet” to discover the holes that critics have been poking in D’Adamo’s research or lack thereof. The plural of “anecdote” is still not “data.”

Unsettlingly, there was a fair amount of what seemed like genuine insight interspersed with the blatant nonsense. Type Os are supposed to have a particular affinity for broccoli and kales, and boy, do I ever! But I ultimately have to dismiss it as a cognitive artifact. The brain craves patterns and will surely find them, whether or not they were there in the first place.

No, I didn't actually attempt the diet. For all I know, it may indeed be the key to a happy and healthy life. I'm still considering this book a loss.

On the other hand, it did provide some inspiration to give up wheat for a few weeks, which seems to have caused me to become noticeably thinner without further effort. So there's that.

(Wait, do you still have another hand free? In the tiny blood type fortune-telling section at the end of each division of the book, he refers to some historical personage as “the penultimate gambler.” Mister, I'm pretty sure that doesn't mean what you think it does. Just saying.)

In the past, Natalia Vodianova was extremely beautiful. According to Google, she only followed one method, which was eating according to the D'Amado blood type group. This time, she has gained weight and looks a bit old, so let's take a look.

Interestingly, when I opened a few paragraphs about my blood type group, I found that it was 80% similar to my current situation and 90% similar to the ideal regime, and only 10% was a bit extreme :(( In the book, it was written that my body has always been guiding me towards the best, but it's just the habitual diet that makes me deviate a little.

Even better, this book is not only a weight loss method but almost everything: personality, psychology, the risk of disease, and even the treatment method. What I like more is that this doctor is in line with my style. That is, it is natural, based on Western medicine but treated in an Eastern way. Since I became independent, I have never used drugs without a prescription. In total, I have only used drugs three times, all according to the prescription, to treat Covid (because I was afraid of losing my hair), my eyes (because I was afraid of going blind), and my teeth (to prevent infection).

What I like even more is that my family has all four blood types, so I have the opportunity to observe closely to see if it is as described. According to the book:
- Blood type O: It is called the ancient blood type of hunters, with characteristics such as being healthy, confident, and leading. In fact, the first blood type to appear was A, but for some reason it disappeared, and O is the basic blood type that treats the first type of people. There is a very cute theory about this group: Because at that time, the land was vast, the population was scarce, and the resources were abundant, so people with blood type O have a deep memory of the paradise-like era. My uncle has blood type O, and I have never seen anyone live so carefree and spend money like dirt =))
- Blood type A: It is the pure agricultural blood type of farmers, with characteristics such as being calm, having good cooperation, and being reserved. This blood type appears when the land begins to be crowded and the labor is divided, so it requires people to know how to be patient and cooperate. My parents have not had their blood tested, so I'm not sure, but one person has blood type A and one person has blood type B (then three children with blood types O, B, and AB can be born). Obviously, my father has blood type A. According to what my grandparents said, and what I have witnessed in my life, my father has never been talkative or angry from childhood to old age. I have also never seen anyone with EQ as high as my father (especially among a group of people from the North who are talkative and hot-tempered), and he is always respected when he goes out.
- Blood type B: It is the balanced blood type of nomads, with characteristics such as being balanced, flexible, and creative. In a peaceful society, there are always some people who are too frustrated and start fighting and invading everywhere, so blood type B was born. My sister (and probably my mother) has blood type B. Both of them are extremely outgoing and easy to get excited =)))
- Blood type AB: It is the modern blood type of mysterious people, with characteristics such as being rare, attractive, and mysterious. This group only accounts for 2 - 5% of the population, and it is impossible to explain why it exists. Humans are the first case where two blood types are combined to form a new blood type. And it is two opposite blood types. (I think it may only be because of love hihi). Before I had my blood tested, I also clearly felt that I was blood type AB, although it is rare. According to what my mother said, since I was in the womb, I have had two personalities :(( I am also the person who is most like my father in the family, and at the same time, the person who is most like my mother in the family. Compared with this book:
+ In terms of diet: Usually, I have eaten 70% fruits and vegetables, 20% seafood, and 10% meat. However, I often feel nauseous and have nightmares when I eat meat, so I have considered giving up meat. This book is right that I should not eat meat (specifically, only turkey can be eaten). I am also struggling with whether to eat fermented foods or not. The book states that fermented foods are very harmful to blood type AB because this group has an excess of microorganisms. In addition, there are some free and unrestricted dishes that I have eaten, but the book writes that they are not good (shrimp, crab, oyster, banana, apple, lychee, durian, mango, orange), so I will give them up. There are only two dishes that I really like to eat but are taboo for AB, which are corn and sour food :(( I will also give them up now. There is a truth in the book that I always have a very strong reaction when I eat chicken and mango. I don't have to argue with my mother about coffee anymore because blood type AB should not drink coffee, but only tea (which is in line with my intention). Just like the "Eat one meal" regime, eating according to blood type also leads to the natural balance of the body's weight.
+ In terms of exercise: I have always said that I am a person who can walk all day but can't run 1 km. This book also says the same: Blood type AB cannot exercise vigorously. I have followed the methods introduced in many books for many years, such as yoga, walking, cycling, and mountain climbing. I also like aikido but don't have the conditions to learn it.
+ In terms of psychology: Although I have two opposite sides in me, according to the book: "Blood type AB has the ability to turn the harm of stress into benefits." Hoho, I immediately recognized this when I read it =)) Basically, I don't know what stress is because stress is always accompanied by joy for me. Or it is an obstacle for me to practice or an object for me to analyze psychology. I always have a hobby when observing myself or the people closest to me to analyze psychology. There is only one time when I was powerless. Some people may say that love is blind, but I believe it is because of the influence of Covid.
Regarding the fact that many people say that I (and people with blood type AB in general) are very difficult to understand, contradictory, and don't know what they want, I would like to refute. I myself feel that I am extremely consistent and clear. It is true that I am sometimes like this and sometimes like that, but it is like two parts of a dialectical relationship, like "Under Pressure" by Queen and Bowie, or as this book writes: "It is the combination of a rare interference between two opposite blood types to blend and adapt." A gray area, a person walking on a tightrope, or as Leonard Bernstein said about art: "A work of art does not answer questions, it provokes them; and its essential meaning is in the tension between the contradictory answers." Or like Zhang Zhen stabbing his crush to death in "A Brighter Summer Day", that is not the contradiction of love but at a very high level. I have talked a lot and felt a bit stunned, but in fact, I am very clear. I can label the emotions of each person, just like those bottles of chemicals. There is no ambiguity or hesitation at all.

In conclusion, I really like this book. Natalia Vodianova is a heroic example. I myself feel that it is basically in line with my perception. It helps to answer many doubts and makes me more confident in living a healthy life ;)) There are a few things that my body insists on but the book says I shouldn't, so I will also give them up now hoho Tonight, the whole family is going to eat grilled corn, and I have to refuse even though I have loved it since childhood huhu The only problem with this book is that there are too many Western ingredients and dishes :((

The Bible never makes any mention of apples. In fact, the Book of Genesis only refers to the fruit from the tree of knowledge. And here's my belief: Eve caused the fall of man with a tomato, which I consider to be the Devil's fruit. All throughout my life, I have felt like an oddity because I have such a strong detestation for that gooey red mess. That was until I read this book.

D'Adamo explains in the introduction that type A blood groups are unable to digest the Devil's fruit due to insufficient stomach acid. This made perfect sense to me, so I went on to read the rest of the book and even gave up milk. Within just 72 hours, I felt significantly better. D'Adamo further elaborates that milk is an antigen and it provokes your immune system. I happen to have MS, which is an immune disorder. By following the dietary regime outlined in this book, it quite possibly saved my life and has definitely slowed the progression of my incurable, degenerative condition. It has also cured my hay fever, arthritis, and even stopped the eczema that my young boys were experiencing.

I wholeheartedly and strongly recommend this book to anyone who is dealing with a health condition, has low energy levels, struggles with weight problems, or has any concerns related to their health. It truly has the potential to change your life for the better.
