"What would you say if I told you that the secret to healthy, vigorous, and disease-free living might be as simple as knowing your blood type," ask Dr. Peter D'Adamo and Catherine Whitney, and in Eat Right 4 Your Type, they shows us the simple answer.

If you've ever suspected that not everyone should eat the same thing or do the same exercise, you're right. In fact, what foods we absorb well and how our bodies handle stress differ with each blood type.

Your blood type reflects your internal chemistry. It is the key that unlocks the mysteries of disease, longevity, fitness, and emotional strength. It determines your susceptibility to illness, the foods you should eat, and ways to avoid the most troubling health problems.

Only recently have all the pieces of the scientific and clinical puzzle started coming together. Dr. D'Adamo has spent the past fifteen years researching the connections among blood type and exercise, food, and disease, and his research is built on thirty years of work done by his father.

In Eat Right 4 Your Type he shows:
which foods, spices, teas, and condiments help someone of your blood type maintain optimal health and ideal weight;
which vitamins and supplements to emphasize or avoid;
which medications function best in your system;
whether your stress goes to your muscles or your nervous system;
whether your stress is relieved better through aerobics or meditation;
whether you should walk, swim or play tennis or golf as your mode of exercise;
how knowing your blood type can help you avoid many common viruses and infections;
how knowing your blood type can help you fight back against life-threatening diseases;
how to slow down the aging process by avoiding factors specific to your blood type that cause rapid cell deterioration.

Eat Right 4 Your Type provides a clear, simple life plan that anyone can follow and suggests the easiest ways to determine your blood type and diet for your blood type. Here is a breakthrough book that will change the way we eat and live.

Blood Type:

The Real
Evolution Revolution

    Blood is life itself. It is the primal force that fuels the power and mystery of birth, the horrors of disease, war, and violent death. Entire civilizations have been built on blood ties. Tribes, clans, and monarchies depend on them. We cannot exist without blood--literally or figuratively.

    Blood is magical. Blood is mystical. Blood is alchemical. It appears throughout human history as a profound religious and cultural symbol. Ancient peoples mixed it together and drank it to denote unity and fealty. From the earliest times, hunters performed rituals to appease the spirits of the animals they killed by offering up the animal blood and smearing it on their faces and bodies. The blood of the lamb was placed as a mark on the hovels of the enslaved Jews of Egypt so that the Angel of Death would pass over them. Moses is said to have turned the waters of Egypt to blood in his quest to free his people. The symbolic blood of Jesus Christ has been, for nearly two thousand years, central to the most sacred rite of Christianity.

    Blood evokes such rich and sacred imagery because it is in reality so extraordinary. Not only does it supply the complex delivery and defense systems that are necessary for our very existence, it provides a keystone for humanity--a looking glass through which we can trace the faint tracks of our journey.

    In the last forty years we have been able to use biological markers such as blood type to map the movements and groupings of our ancestors. By learning how these early people adapted to the challenges posed by constantly changing climates, germs, and diets, we are learning about ourselves. Change in climate and available food produced new blood types. Blood type is the unbroken cord that binds us to one another.

    Ultimately, the differences in blood types reflect upon the human ability to acclimate to different environmental challenges. For the most part, these challenges impacted the digestive and immune systems: a piece of bad meat could kill you; a cut or scrape could evolve into a deadly infection. Yet the human race survived. And the story of that survival is inextricably tied to our digestive and immune systems. It is in these two areas that most of the distinctions between blood types are found.

The Human Story

The story of humankind is the story of survival. More specifically, it is the story of where humans lived and what they could eat there. It is about food--about finding food and moving to find food. We don't know for certain when the human evolution began. Neanderthals, the first humanoids we can recognize, may have developed 500,000 years ago. Maybe more.

    We do know that human prehistory began in Africa, where we evolved from humanlike creatures. Early life was short, nasty, and brutish. People died a thousand different ways--opportunistic infections, parasites, animal attacks, broken bones, childbirth--and they died young.

    Early humans must have had a harrowing time providing for themselves in this savage environment. Their teeth were short and blunt--ill suited for attack. Unlike most of their competitors on the food chain, they had no special abilities with regard to speed, strength, or agility. Initially, the chief quality humans possessed was an innate cunning, which later grew to reasoned thought.

    Neanderthals probably ate a rather crude diet of wild plants, grubs, and the scavenged leftovers from the kills of predatory animals. They were more prey than predator, especially when it came to infections and parasitic afflictions. (Many of the parasites, worms, flukes, and infectious microorganisms found in Africa do not stimulate the immune system to produce a specific antibody to them, probably because the early Type O people already had protection in the form of the antibodies they carried from birth.)

    As the human race moved around and was forced to adapt its diet to changing conditions, the new diet provoked adaptations in the digestive tract and immune system necessary for it to first survive and later thrive in each new habitat. These changes are reflected in the development of the blood types, which appear to have arrived at critical junctures of human development:

1. The ascent of humans to the top of the food chain (evolution of Type O to its fullest expression).

2. The change from hunter-gatherer to a more domesticated agrarian lifestyle (appearance of Type A).

3. The merging and migration of the races from the African homeland to Europe, Asia, and the Americas (development of Type B).

4. The modern intermingling of disparate groups (the arrival of Type AB).

    Each blood type contains the genetic message of our ancestors' diets and behaviors, and though we're a long way away from early history, many of their traits still affect us. Knowing these predispositions helps us to understand the logic of the blood type diets.

O Is for Old

The appearance of our Cro-Magnon ancestors in around 40,000 B.C. propelled the human species to the top of the food chain, making them the most dangerous predators on earth. They began to hunt in organized packs; in a short time, they were able to make weapons and use tools. These major advances gave them strength and superiority beyond their natural physical abilities.

    Skillful and formidable hunters, the Cro-Magnons soon had little to fear from any of their animal rivals. With no natural predators other than themselves, the population exploded. Protein--meat--was their fuel, and it was at this point that the digestive attributes of Blood Type O reached their fullest expression.

    Humans thrived on meat, and it took a remarkably short time for them to kill off the big game within their hunting range. There were more and more people to feed, so competition for meat became intense. Hunters began fighting and killing others who were impinging on what they claimed were their exclusive hunting grounds. As always, human beings found their greatest enemy to be themselves. Good hunting areas became scarce. The migration of the human race began.

    By 30,000 B.C., bands of hunters were traveling farther and farther in search of meat. When a shift in the trade winds desiccated what had been fertile hunting land in the African Sahara, and when previously frozen northern areas grew warmer, they began to move out of Africa into Europe and Asia.

    This movement seeded the planet with its base population, which was Blood Type O, the predominant blood type even today.

    By 20,000 B.C. Cro-Magnons had moved fully into Europe and Asia, decimating the vast herds of large game to such an extent that other foods had to be found. Searching each new area for anything edible, it is likely that the carnivorous humans quickly became omnivorous, with a mixed diet of berries, grubs, nuts, roots, and small animals. Populations also thrived along the coastlines and the teeming lakes and rivers of the earth where fish and other food were abundant. By 10,000 B.C., humans occupied every main landmass on the planet, except for Antarctica.

    The movement of the early humans to less temperate climates created lighter skins, less massive bone structures, and straighter hair. Nature, over time, reacclimated them to the regions of the earth they inhabited. People moved northward, so light skin developed, which was better protected against frostbite than dark skin. Lighter skin was also better able to metabolize vitamin D in a land of shorter days and longer nights.

    The Cro-Magnons eventually burned themselves out; their success was anathema. Overpopulation soon exhausted the available hunting grounds. What had once seemed like an unending supply of large game animals diminished sharply. This led to increased competition for the remaining meat. Competition led to war, and war to further migration.

A Is for Agrarian

Type A blood initially appeared somewhere in Asia or the Middle East between 25,000 and 15,000 B.C. in response to new environmental conditions. It emerged at the peak of the Neolithic period, or New Stone Age, which followed the Old Stone Age, or Paleolithic period, of the Cro-Magnon hunters. Agriculture and animal domestication were the hallmarks of its culture.

    The cultivation of grains and livestock changed everything. Able to forgo their hand-to-mouth existence and sustain themselves for the first time, people established stable communities and permanent living structures. This radically different lifestyle, a major change in diet and environment, resulted in an entirely new mutation in the digestive tracts and the immune systems of the Neolithic peoples--a mutation that allowed them to better tolerate and absorb cultivated grains and other agricultural products. Type A was born.

    Settling into permanent farming communities presented new developmental challenges. The skills necessary for hunting together now gave way to a different kind of cooperative society. For the first time, a specific skill at doing one thing depended on the skills of others doing something else. For example, the miller depended on the farmer to bring in his crops; the farmer depended on the miller to grind his grain. One no longer thought of food as only an immediate source of nourishment or as a sometime thing. Fields needed to be sown and cultivated in anticipation of future reward. Planning and networking with others became the order of the day. Psychologically, these are traits at which Type As excel--perhaps another environmental adaptation.

    The gene for Type A began to thrive in the early agrarian societies. The genetic mutation that produced Type A from Type O occurred rapidly--so rapidly that the rate of mutation was comparable to four times that of Drosophila, the common fruit fly and current record holder!

    What could have been the reason for this extraordinary rate of human mutation from Type O to Type A? It was survival. Survival of the fittest in a crowded society. Because Type A emerged as more resistant to infections common to densely populated areas, urban, industrialized societies quickly became Type A. Even today, survivors of plague, cholera, and smallpox show a predominance of Type A over Type O.

    Eventually, the gene for Type A blood spread beyond Asia and the Middle East into western Europe, carried by the Indo-Europeans, who penetrated deeply into the pre-Neolithic populations. The Indo-European hordes originally appeared in south-central Russia, and between 3,500 and 2,000 B.C. pushed southward into the top of southwestern Asia, creating the populations and peoples of Iran and Afghanistan. Ever burgeoning, they moved further westward into Europe. The Indo-European invasion was really the original Diet Revolution. It introduced new foods and lifestyle habits into the simpler immune systems and digestive tracts of the early hunter-gatherers, and those changes were so profound that they produced the environmental stress necessary to spread the Type A gene. In time, the digestive system of the hunter-gatherers lost its ability to digest its carnivorous pre-agricultural diet.

    Today, Type A blood is still found in its highest concentration among western Europeans. The frequency of Type A diminishes as we head eastward from western Europe, following the receding trails of the ancient migratory patterns. Type A peoples are highly concentrated across the Mediterranean, Adriatic, and Aegean seas, particularly in Corsica, Sardinia, Spain, Turkey, and the Balkans. The Japanese also have some of the highest concentrations of Type As in eastern Asia, along with a moderately high number of blood Type Bs.

    Blood Type A had mutated from Type O in response to the myriad infections provoked by an increased populace and major dietary changes. But Blood Type B was different.

B Is for Balance

Blood Type B developed sometime between 10,000 and 15,000 B.C., in the area of the Himalayan highlands--now part of present-day Pakistan and India.

    Pushed from the hot, lush savannahs of eastern Africa to the cold, unyielding highlands of the Himalayas, Blood Type B may have initially mutated in response to climactic changes. It first appeared in India or the Ural region of Asia among a mix of Caucasian and Mongolian tribes. This new blood type was soon characteristic of the great tribes of steppe dwellers, who by this time dominated the Eurasian plains.

    As the Mongolians swept through Asia, the gene for Type B blood was firmly entrenched. The Mongolians spread northward, pursuing a culture dependent upon herding and domesticating animals--as their diet of meat and cultured dairy products reflected.

    Two distinct Type Bs sprang up as the pastoral nomads pushed into Asia: an agrarian, comparatively sedentary group in the south and the east; and a nomadic, warlike society conquering the north and the west. The nomads were expert horsemen who penetrated far into eastern Europe, and the gene for Type B blood is still in strong evidence in many of the eastern European populations. In the meantime, an entire agriculturally based culture had spread throughout China and southeast Asia. Because of the nature of the land they chose to till, and climates unique to their areas, these peoples created and employed sophisticated irrigation and cultivation techniques that displayed an awesome blend of creativity, intelligence, and engineering.

    The schism between the warlike tribes to the north and the peaceful farmers to the south was deep, and its remnants exist to this day in southern Asian cuisine, which uses little if any dairy foods. To the Asian mind, dairy products are the food of the barbarian, which is unfortunate because the diet they have adopted does not suit Type Bs as well.

    Of all the ABO types, Type B shows the most clearly defined geographic distribution. Stretching as a great belt across the Eurasian plains and down to the Indian subcontinent, Type B is found in increased numbers from Japan, Mongolia, China, and India up to the Ural Mountains. From there westward, the percentages fall until a low is reached at the western tip of Europe.

    The small numbers of Type B in Old and Western Europeans represents western migration by Asian nomadic peoples. This is best seen in the easternmost western Europeans, the Germans and Austrians, who have an unexpectedly high incidence of Type B blood compared to their western neighbors. The highest occurrence of Type B in Germans occurs in the area around the upper and middle Elbe River, which had been nominally held as the dividing line between civilization and barbarism in ancient times.

    Modern subcontinental Indians, a Caucasian people, have some of the highest frequencies of Type B blood in the world. The northern Chinese and Koreans have very high rates of Type B blood and very low rates of Type A.

    The blood type characteristics of the various Jewish populations have long been of interest to anthropologists. As a general rule, regardless of their nationality or race, there is a trend toward higher-than-average rates of Type B blood. The Ashkenazim and the Sephardim, the two major Jewish sects, share strong levels of Type B blood, and appear to have very few differences. The pre-Diaspora Babylonian Jews differ considerably from the primarily Type O Arabic population of Iraq (the location of the biblical Babylon) in that they are primarily Type B, with some frequency of Type A.

AB Is for Modern

Type AB blood is rare. Emerging from the intermingling of Type A Caucasians with Type B Mongolians, it is found in less than 5 percent of the population, and it is the newest of the blood types.

    Until ten or twelve centuries ago, there was no Type AB blood. Then barbarian hordes sliced through the soft underbelly of many collapsing civilizations, overrunning the length and breadth of the Roman Empire. As a result of the intermingling of these Eastern invaders with the last trembling vestiges of European civilization, Type AB blood came to be. No evidence for the occurrence of this blood type extends beyond nine hundred to a thousand years ago, when a large western migration of eastern peoples took place. Blood Type AB is rarely found in European graves prior to A.D. 900. Studies on exhumations of prehistoric graves in Hungary show a distinct lack of this blood group into the Longobard age (fourth to seventh century A.D.). This would seem to indicate that up until that point in time, European populations of Type A and Type B did not come into common contact, or if so, did not mingle or intermarry.

    Because Type ABs inherit the tolerance of both Type A and Type B, their immune systems have an enhanced ability to manufacture more specific antibodies to microbial infections. This unique quality of possessing neither anti-A nor anti-B antibodies minimizes their chances of being prone to allergies and other autoimmune diseases such as arthritis, inflammation, and lupus. There is, however, a greater predisposition to certain cancers because Type AB responds to anything A-like or B-like as "self," so it manufactures no opposing antibodies.

    Type AB presents a multifaceted, and sometimes perplexing, blood type identity. It is the first blood type to adopt an amalgamation of immune characteristics, some of which make them stronger, and some of which are in conflict. Perhaps Type AB presents the perfect metaphor for modern life: complex and unsettled.

The Blending Grounds

Blood type, geography, and race are woven together to form our human identity. We may have cultural differences, but when you look at blood type, you see how superficial they are. Your blood type is older than your race and more fundamental than your ethnicity. The blood types were not a hit-or-miss act of random genetic activity. Each new blood type was an evolutionary response to a series of cataclysmic chain reactions, spread over eons of environmental upheaval and change.

    Although the early racial changes seem to have occurred in a world that was composed almost exclusively of Type O blood, the racial diversifications--coupled with dietary, environmental, and geographical adaptations--were part of the evolutionary engine that ultimately produced the other blood types.

    Some anthropologists believe that classifying humans into races invites oversimplification. Blood type is a far more important determinant of individuality and similarity than is race. For example, an African and Caucasian of Type A blood could exchange blood or organs and have many of the same aptitudes, digestive functions, and immunological structures--characteristics they would not share with a member of their own race who was Blood Type B.

    Racial distinctions based on skin colors, ethnic practices, geographical homelands, or cultural roots are not a valid way to distinguish peoples. Members of the human race have a lot more in common with one another than we may have ever suspected. We are all potentially brothers and sisters. In blood.

Today, as we look back on this remarkable evolutionary revolution, it is clear that our ancestors had unique biological blueprints that complemented their environments. It is this lesson we bring with us into our current understanding of blood types, for the genetic characteristics of our ancestors live in our blood today.

* Type O: The oldest and most basic blood type, the survivor at the top of the food chain, with a strong and ornery immune system willing to and capable of destroying anyone, friend or foe.

* Type A: The first immigrants, forced by the necessity of migration to adapt to a more agrarian diet and lifestyle ... with a more cooperative personality to get along in crowded communities.

* Type B: The assimilator, adapting to new climates and the mingling of populations; representing nature's quest for a more balanced force between the tensions of the mind and the demands of the immune system.

* Type AB: The delicate offspring of a rare merger between the tolerant Type A and the formerly barbaric but more balanced Type B.

    Our ancestors left each of us a special legacy, imprinted in our blood types. This legacy exists permanently in the nucleus of each cell. It is here that the anthropology and science of our blood meet.

i bought this book four years ago at the recommendation of a friend. i found the diet to be quite an adjustment at first. i am type O and i should be a meat/fish/poultry eater which was not a problem, but i had to cut out wheat, corn, vinegar, pork, wine, coffee and many other thigns that i love but were on my avoid list. i tried the diet for one year and had tremendous results. i lost weight, felt energized and generally well balanced. i also participated in martial arts training like kickoxing prior to the diet, but dr. d'adamo actually said that martial arts is one of the best exercises for type o's. then i got married and completely fell off the diet and exercise regimine. needless to say i gained weight, fought depression, eliminated my libido, etc. i am now getting divorced, due to other circumstances, but i felt the need to improve my current situation in light of this. i recently reread dr. d'adamo's books and committed to going back on the diet. i also began going to my martial arts classes after a four year hiatus. after two weeks back on the diet and exercise program i am feeling much better. again, more energy, and mental clarity. and the best part is i have already lost seven pounds. i recommend that everyone at least buy the booka nd have an open mind. try the diet for one month. i promise the results will compell you to stick with it. i just wish i had had the sense to stick with it once i got married. but, hey it's never too late to get with, or back to , the program.

I had been struggling for years with my diet. I'd crave protein and nuts which would completely blow my conventional diet but I found this was due to eating the wrong foods for my blood type. Moving to the O blood type diet I dropped 10 pounds in the first 15 days and it was right from my stomach and back BUT the most important thing is my memory came back!!! I am post surgical menopause and I have been in a fog for years. I had chalked it up to be over 45 and had come to terms that this was now my life, NOT SO! My head is clear and I am recalling things at a snap. It has renewed my life and well worth the price of the book.

This book was recommended to me because of a discussion about how I like some foods BUT some foods don't like me. (My reaction to those foods were extreme.) I started reading this book and couldn't put it down. Now... I know why my system reacts the way it does. I am type O, and I stopped eating wheat products,cheese & changed to pineapple juice instead of O.J.: What a difference!! By altering my diet, I feel so much better. Very glad I took the time to read this book.

Only two weeks after purchasing this book and the encyclopedia, starting the first week by omitting the avoid foods 50%;second week getting serious, I am here to report the results are truly amazing. I am AB and my husband and his twin boys are O. They came into my life 8 years ago.I am the pleaser, so I proceeded to cook all the good stuff for them! They longed for Meat and they got it and so did I. Only to wind up with cholesterol level at 319 a year ago! My doctor put me on synthroid, six weeks later I was down to 235. But my good cholesterol was twice as high. So no more concerns on part of my doctor. I was still sluggish and had to endure the aches and stiff joints associated with a malajusted thyroid. Thanks to this diet I have no pains, stiffness after only two weeks. I can not wait for my next blood test in 10 weeks! I wish more health professionals where open to the possibilitys of this plan for a healtier being. My eating habbits before this new family of mine almost coincided with doctor D'Adamos diet. I grew up in northern germany, where my diet concisted of 6 days fish and one day meat! Later I lived in hawaii, my best girl friends husband being a commercial fisherman supplying me with ample amounts of fish! Fresh vegetables from the chinese market rounded my diet! Bottom line, I am turning into the energetic, happy woman my husband and the twins met 8 years ago! I dont have much weight to loose, but the health benefits are enormous for me. Thanks Dr. D'Adamo!

Loved this book, and am telling all my friends about it. I've been following the diet pretty faithfully, and have lost 9.5 pounds in 15 days! It gives a lot of variety in each blood type plan.

I am overweight and that is the main reason I purchased this book. After I started reading it, and doing what it says...I began to FEEL better. I tend to have stomach upsets very frequently and I had decided that it was something I was just going to have to live with, but I haven't had one since I have been using the guidelines in this book. Feeling better has lead me to having the energy to workout more, and although this is not a "weight loss" book, it does give advice about foods for your blood type that are good for weight loss as well as exercises that are best suited for your blood type and how often you should engage in them. It is not a diet you do for a few weeks, it is a lifestyle change. If you are looking for a typical diet where you only drink lemon juice for a week, this is not the book for you. If you want to change your life, even if you are not overweight, but if you have a general unhealthy demeanor this is the book for you. The only down side is you should expect to have to cut out some foods you like, I'm sure there will be some...there certainly are for me, but I had reached a point where I felt horrible all the time and my weight was becoming a problem. Following the guidelines has even helped my asthma. The pros outweigh the cons by a long shot for me. Being able to go hiking with my husband, (who played college football) and actually keeping up is fantastic! If you are tired of feeling bad all the time or being overweight I highly recommend this book. I hope it works as well for you as it has thus far for me.

This book starts with a fascinating history and overview about how blood types evolved and the culture related to blood types around the world. I found that all blood types have their strengths and challenges and there are amazing tendencies on food sensitivities that can make a big difference on over all fitness. Making chances to read other authors and cross references points of view, helps me find what works for me.

I was surprised that in the past many have looked down on my blood type, O which is common on both sides of the family and quite rare and ironically otherwise, many of my characteristics are more modern. It clearly explained the difference between evolved characteristics as opposed to genetic innovations. I'm O+ and that explained a lot about why some of my challenges show up as they do. I knew before I read the book that I would break out if I ate about a half dozen chocolate oatmeal cookies, and one of the first things that jumped out at me was peanuts can be trouble for people with O blood. This boosts my interest to study more about nutritional healing, and it's fun to find healthy ways to satisfy my sweet tooth and enjoy the rest of the balance of my diet, too.

This book is great! It all makes sense now. A lot of the food that I was eating and weren't going well with my digestive system are all the foods noted that are not beneficial for my body. I have been following this diet for a month and two weeks. As a result, I have no more migraines or headaches that last three days, my allergies have significantly subsided and I have lost more than seven pounds (although I wasn't trying). I get compliments on my skin and I am more alert. I do cheat from time to time but pay the consequences afterward by either getting sick or breaking out in hives. Moderation is key but it's worth it. It changed my life for the better.

Tremendous - struck just the right cord for me. Felt benefits from diet within 1 week. Lost 20 lbs in 4 months, lowered cholesterol 30 points. Bad numbers went down about 1/3, good numbers up about 10%. My Doctor was amazed at the improvement in blood work up, took me off Zocor Rx and asked for the name of the diet. I have kept the weight loss off for an additional 6 weeks.

My husband had terrible allergies and stomach problems and had tried all sorts of medicines. Nothing worked. In addition to homeopathic remedies, we have adopted the eating plans this book describes. What a difference it has made!!! I never thought my husband could do this diet (he is a big football player kind of guy) but he has found new things to eat and has given up some of his old eating habits. Now, we both find that if we 'splurge' for foods not recommended for us, we notice it! We feel so much better now that we're following these eating guidelines. Give it a try! You'll be amazed!!

I thought the idea of this diet was a bunch a baloney when I heard about it, but after suffering with IBS, Acid Reflux, and having my gallbladder removed, all before I was thirty, I was willing to try it! I've been told by Dr's to increase fiber, eat more cereals, more H20, take stimulants like Fibercon and Milk of Magnesia, and YUCK, none of it worked. I tried the Atkins diet and felt as if I might die! I've tried a series of digestive enzymes and still, no help. I was at a loss. I already had a restricted diet due to my allergies of MSG, Caffeine, alcohol, dairy and others that make me feel ill. Low and behold, then I read the food list for type O and almost all the foods that irritate me were foods that O types should not eat! After 1 week on the diet I lost 5 lbs. lost the bloating, my synthroid levels had gotten better and where is the IBS? GONE! I don't know how much of the science behind this book can be proven, but I do know it worked for me and I'm eating HEALTHY. I would recommend anyone to give this book a try!

My mother got me started on the Eat Right 4 Your Type Lifestyle. It is not just a diet.... it's a way of life. My mother has lupus. This 'diet' helped her get off of all the medications she was on. Eating right and taking the right supplements was all she needed to manage her illness. My son developed diabetes about a year ago. It was hard to control his sugar levels being as he was only 16 months old at diagnosis. He also had continous ear infections. When the doctor suggested tubes Mom suggested I check into changing his diet. So I did....And it has worked wonders. I think everyone should educate themselves about bloodtypes and allergies. Get off all the antibiotics and such! If they really worked....would you have to keep taking them??? Just check it out!

What a life changer this book has been for me. Since my teens I had been dealing with IBS. Instead of finding the cause of the problem every doctor that I have been to prescribed medications and told me to eat a diet rich with grains. Isn't this ironic? As a type O I have an intolerance to wheat and most grains, so instead of feeling better it just made my situation worse. When I eliminated those items listed as avoid for my blood type, all my health problems disappeared. No more yo-yo dieting, no more calorie counting, I'm not hungry all the time, and I now have lean muscle mass.

I have been on this type of diet for about 3 weeks now. Have lost 8.5 lbs!!! More important is the fact that my stomach doesn't hurt anymore! Feel so much better eating what I should and not all the other things that were hurting me

I am very intrigued by this form of health maintinience. I WONT SAY DIET because I find that this book is not all about that; its about Optimal Health overall. I expect to see more changes as alot of the not too eat foods r the ones that i notice make me feel out of sorts even before reading this so this book to me is nothing but a confirmation & valuable addition on my personal health journey. My blood type is A positive btw. Good luck & happy readings :-)

In early 2010 I began to look at what I was eating and started to look at the gluten and grains in my diet. I lost over 40 pounds in a very short time. Just a couple of months ago I read an article on this "idea" of eating for your blood types in some health magazine (can't remember the name now) and decided to pick up this book. With very few exceptions I was amazed that I was literally following the diet for the type "O"! A friend of mine who is a Type A decided to follow the guidelines in book and she was swept away by the amount of weight that she too has lost following the recommendatons. This is an intelligent read and well worth having in your reference library. You will refer to it again and again.

After a friend recommended this book, it took a while for the theory to soak through my wheat, gluten and sugar addled brain. Once I started following the type O plan, I basically melted. Only when I relapse and revert to bad eating habits does weight gain, brain fog, and generally bad health return. What sold me was the number of avoids and goods listed for my type that were already known to me for various reasons. I developed a strong sensitivity to raw citrus in my 30's after years of craving it. No citrus, no uncontrollable sleep reaction, burning or sores. Amazing! Little to no pasta and cheese, little to no offensive gas and the associated pain. Only sorry I didn't know about this when there may still have been a chance to avoid many of the problems that led to infertility and pain that ended up with a medically necessary hysterectomy at 42, after nearly bleeding to death! My siblings, both parents and many relatives are type II diabetics and suffer from other weight and health problems. I haven't avoided all of them, because I didn't start this life change until my 40's, but at 58, still have no sign of developing diabetes and great cholesterol levels, as well as clarity of thought unless I over-indulge in glutens and sugars. Truly a life saver for me!

I've had great success with this eating approach...FOLLOWING SOMEBODY ELSE'S BLOOD TYPE! I'm a type A positive and I felt sick and terrible following the advice from my chapter. I don't tolerate gluten well, it cut out nearly all meat and dairy, and advised me against what had always been superfoods for me like bananas. When I decided to try eating for the type O positive diet, just to see what would happen, it was like somebody flipped a switch in me and I immediately felt like superman! I had amazing energy, my weight started dropping so fast it actually scared me enough to make a quick appointment with my primary care doctor to make sure there wasn't something wrong with me. I told her about the diet and she did a quick blood type test along with the other things she'd ordered and, sure enough, I really am A positive. I guess my digestive system thinks I'm an O! I'm sticking with one of the diets from the book, just not the one the doctor who wrote it recommended for me. I gave it three stars for this reason, it works but not the way the doc says it should! At least in my case. If you try it and it's not working for you, maybe try shopping around to the other blood types??? I'm just glad I found something that works so well, I don't really care how or why or what it took to get there. :)

When I was offered this book I did not make a big deal of it. When I was done with the book however I felt empowered with a new set of tools that gave me a chance to choose. The best feeling of it all was that I knew what I was eating and why.

Dr. D'Adamo is a genius!! I would like to thank both him and his father. There are so many things I love about his book. Though Dr. D'Adamo is Type A, he is unsparingly honest about the dangers faced by Type A people, and that intrigued me enough to try it. I threw it aside in disgust, though because he said that Type B (myself and half my family) shouldn't have Chicken/Pork/Shellfish/Tomatoes/Wheat/Corn (The staples of my entire eating life!) I got back on Atkins, and lost for a while, but ran into a brick wall. In despair, I picked up Eat right 4/for your Type, and in THREE DAYS THE AGONIZING PAINS I ENDURED FOR TEN YEARS WERE GONE. Amazing!! I've taken off 77 lbs and everyone I know is begging for my secret. What I like is that the Blood type diet is 4 lifestyles in one, and it cleared up so many mysteries, like why I like golf, and swimming, and hate contact sports with a passion. I went out for volleyball and basketball in school and failed dismally, leaving emotional scars. Who would have thought one book would clear up so many questions. Check out his books on diabetes, arthritis, and cancer, and his hilarious emails on his website.

I ordered this book after my doctor requested me to do so. I have read it completely and will try to follow everything it requires regarding my diet. It was well written with useful research about the success and failures of some diets and why and useful, easy to understand diet plans. The book has made me so glad that I didn't try any of the fad diets of the past because this book is all I need. This is a challenge I look forward to.

I began the program two weeks ago. I did see a drop in weight and inches. I am not restricted in any way on this program because the foods recommended for my type are the foods that I desire to eat. Along with my shrinking waistline is my grocery bill. It has decreased since I no longer buy the foods that I did not want to buy, but did so because they were 'good' for me. This book is quite a contribution to our society.

I bought this book at my health foods store. It helped me plan healthy diets for the people I take care of. If you want to lose weight this book can help.
