BLOOD TYPE AND NUTRITION: A PERSPECTIVE FOR VEGETARIAN DIETS

Blood Type and Nutrition: A PERSPECTIVE FOR VEGETARIAN DIETS

A number of readers of NVNH have inquired about the merits of a book which recommends flesh foods as the best form of protein for certain blood types. The following article offers a solution to this concern.

In the nutritional programs advanced below, some points are at odds with the Natural Health Dietary Guidelines that were spelled out in the previous issue. However, new information should always be considered, and there are always people who will benefit by adopting some or all of the new concepts presented.

In his new book, The Eat Right Diet, Dr Peter D'adamo introduces the concept of dietary lectins - and their potential to influence the capacity of all bodily organ systems to function effectively. I have been using the principles espoused in his book in my practice since late 1997 with great success and have reduced the need for food sensitivity testing in people suffering from allergic complaints. There have been some instances where I have seen health problems such as arthritis, diabetes and skin disorders resolved by dietary therapy alone using D'adamo's nutritional concepts.
However, one pressing concern for people on vegetarian diets is his recommendation for those with `O' and `B' blood types to consume more animal protein while reducing intake of unsuitable grains and plant proteins. I would certainly agree that his nutritional programming appears to be encouraging these blood types, the `O' blood type in particular, to consume foods considered to be highly unethical by serious vegetarians.

With this in mind, in July 1999 I ventured to the Gold Coast and the International Congress on Natural Medicine where Dr. Peter D'adamo was to speak. After much discussion with him, it emerged that he is a true humanitarian, and while he indicated that `O' and `B' types do benefit from animal proteins, he made it quite clear that vegetarians from these blood groups can achieve good health without consuming flesh and animal-derived proteins.

I am convinced his program will gain wide acceptance in the Australian naturopathic community. My charter is to see D'adamo's work and theories interpreted correctly. In this article I would like to illustrate how `O' & `B' blood-type individuals can implement the basic tenets of the blood-type diet while maintaining their vegetarian way of eating.

THE LECTIN-BLOOD TYPE CONNECTION

D'adamo's theories are based on a chemical reaction taking place between your blood and the foods you eat. Due to the so-named lectins contained within foods, your immune and digestive systems still maintain favouritism for foods that your blood-type ancestors ate. Lectins are an abundant and diverse range of proteins found in foods - predominantly seeds and particularly those of legumes - that seek out and bind to carbohydrates in red blood cells.

Your blood-type antigen is one of 4 different carbohydrate structures that stick out and label every one of your red cells as either `O', `A', `B' or `AB' blood type. (An antigen is a foreign substance which stimulates an immune response.) Certain lectins that are incompatible with specific blood-type carbohydrate antigens will attach themselves to that antigen, leading to blood cell clumping or agglutination. Once cells are agglutinated, they become targeted for destruction by the immune system as if they were some type of foreign invader.

Your blood-type antigen is found not only on your red blood cells, it is also extensively expressed in digestive mucus, gastric-acid secretions, pancreatic juices and bile. So if you eat food lectins that are offending for your blood type, in addition to agglunating your red cells, they also have the potential to cause bodily cells in the digestive tract to clump together and lead to an immune system response.

For example, when blood type 'A' people drink cow's milk, the milk lectin can interact directly with cells along the digestive tract lining, resulting in localized inflammation with symptoms such as bloating, flatulence, gut cramping & discomfort. For a person with digestive system problems, looking at red blood cells via live blood analysis is an excellent tool by which we can determine what is happening to similar cells in the digestive system.

In the past, practitioners using live blood microscopy, like myself, have related the picture in photo B to having excess protein in the diet, or to the patient being incapable of effectively assimilating protein. However, it seems that eating harmful lectins in foods is also a major determinant of cellular agglutination which will occur throughout the whole body. Because red blood cells bring oxygen to every cell in the body, this is very undesirable and you will become more fatigued. Agglutination is also reflective of an increase in organic acid level within the body, which accelerates the rate at which you age and increases the risk of developing infectious illness, cancer and heart disease.

THE PROTEIN EQUATION

Your day-to-day energy levels and endurance are partly determined by how well you assimilate protein. This assimilation can be impaired by many factors such as the consumption of those dietary lectins that cause localized inflammation in the villi of the digestive tract lining. The inflammation prevents the uptake of amino acids and other nutrients, often bringing on symptoms like bloating, fatigue and/or sugar cravings after the meal.

So what's the answer?

We don't want to make the mistake of over-eating protein in order to compensate for any inadequacies in assimilating these amino acids. The adult body needs about 40 grams of pure protein daily to maintain metabolic equilibrium, which amounts to 0.5 - 0.7 grams protein for every kilogram of ideal body weight. This amounts to approximately 30 - 50 grams of protein a day which should be delivered over a minimum of 3 daily serves. The challenge is to optimize the utilization of these dietary proteins.

Plant proteins are more likely to be digested into their constituent amino acids and then absorbed into the bloodstream. These amino acids are easier for bodily cells to utilize in cell construction. Vegetarian proteins will also improve cellular respiration within mitochondria.

In the context of blood typing, we need to eat beneficial or neutral vegetarian proteins in combination with grains and vegetables that don't contain lectins that impair digestive system function and amino-acid uptake.

By consuming only beneficial lectins, we also encourage the growth of friendly gut bacteria which further improves the uptake of amino acids from the plant proteins. The lacto/ovo `O' and `B' blood-type individuals can also add milk and egg proteins to the range from which amino acids can be derived. D'adamo assured me that O- and B-type vegetarians can have optimal health if they choose their plant proteins and meal combinations wisely.

O-type program overview

The main point to remember is to avoid combining your beneficial and neutral vegetarian proteins with offending lectins in grains, vegetables and fruits. Make up your daily protein allowance from any of the neutral or beneficial vegetarian proteins listed in the above table.

CEREAL GRAINS: Wheat and corn (maize) contain lectins such as gluten and others that react with the blood and digestive tract cells, and interfere with proper assimilation of amino acids, minerals and other nutrients - as explained earlier. While wheat is by far the worse offender, by avoiding lectins from both grains you can maximize the assimilation of the nutrients in your protein foods. `O' blood types should focus on reducing the total intake of grains and selecting more often from rice, oats, millet, rye and barley. `O' types are better to get starch from vegetables such as parsnip, peas and sweet potato and to increase the intake of other vegetables and fruits. It is important to substitute fruit for that piece of bread between meals.

VEGETABLES: The Nightshade vegetables, in particular eggplant, potatoes, capsicum & chilli, cause arthritic conditions in type `O's, because their lectins deposit in the tissues surrounding the joints. Sweet-corn lectins affect the production of insulin, and, like the lectin in wheat, can lead to obesity and mature-onset diabetes. The assimilation of proteins will be enhanced by avoiding combinations with potato and corn in the same meal. Alfalfa sprouts contain components that, by irritating the digestive tract, can aggravate type `O' hypersensitivity problems. The moulds in cultivated mushrooms and fermented olives also tend to trigger allergic reactions.

FRUITS: Rockmelons and honeydew melons contain very high mould counts so should be avoided. Oranges, tangerines and strawberries should be avoided due to the high acidic reaction they induce in the digestive tract. The type `O' digestive tract already has high acidity and needs the balance of the alkaline fruits to reduce the possibility of ulceration and irritation to the stomach and duodenal lining. Blackberries, contain a lectin that aggravates type `O' digestion so are also better avoided.

B-type program overview

For `B'-type vegetarians the best advice I can offer is to adopt a lacto/ovo vegetarian style of eating. `B' types utilize the lacto/ovo range of proteins more effectively than any other blood group and these can be liberally included by `B' types who are not lactose-intolerant. Type-`B' individuals of Asian or African descent are more likely to be lactose-intolerant, and in these cases the sheep's and goats' milk selections may be more suitable. Type-'B' vegans still have a range of legumes and nuts to select from, while taking care not to consume them simultaneously with the grains and vegetables that may shut down digestion and cellular metabolism (see below).

CEREAL GRAINS: Wheat, corn and buckwheat lectins are all capable of disrupting digestion and metabolism. Rye, rather than affecting digestion, contains a lectin that settles in the vascular system causing blood disorders and the potential for stroke. Rice and oats are probably the best grains to use in combination with your protein foods to maximize amino-acid assimilation.

VEGETABLES: Tomatoes can irritate the digestive-tract lining, so are best avoided. I have often seen `B' individuals who have at times observed completely undigested tomato in their stools. Sweet-corn can disturb insulin metabolism and is best avoided, as are olives that contain moulds which can trigger allergic-type gut reactions. Use sweet potato, parsnip, potatoes and peas as alternatives to what are normally good starchy grains - rice, millet and oats.

SUMMING UP

The basic tenets of the blood-type program are easy to follow even if you are vegetarian. As lectins are present in very high concentrations in legumes, nuts, seeds and grains, it is essential that vegetarians select proteins in those food groups that will not disrupt digestion or metabolism. This point should be emphasized even more for those who suffer from digestive disturbances, weight problems, sugar intolerance or immune deficiency syndromes.

If your blood type is either `O' or `B', there is still a wide range of suitable plant proteins or lacto/ovo proteins available to eat. As long as they are eaten with carbohydrates containing friendly lectins, you should be able to combine proteins and starches provided no other underlying gut disturbance is present. Remember, that problems such as pancreatic insufficiency, bacterial and fungal dysbiosis, hypo-chlorhydria (low stomach acid) and poor quality bile production will also require therapeutic correction if your digestion and health are to improve markedly while implementing bloodtyping changes to your diet. By attending to any such problems simultaneously with these changes, you can expect to notice big improvements in health, ranging from energy levels to raised immunity.

By choosing foods containing lectins favourable for your blood type, you will be encouraging the growth of beneficial bacteria in your digestive tract. This will underpin any improvement in your ability to assimilate the nutrients in your diet. Of course, if you select foods with unfriendly lectins, then expect a proliferation of unfriendly microbes which will undermine good digestion and metabolism.

A:

The debate between vegetarians and meat-eaters has raged for years. Some claim that vegetarian diets do not contain sufficient protein. Others contend that human beings were never meant to be flesh-eaters. In The D'Adamo Diet neither or perhaps both viewpoints hold true: the book allows that individual bodies have individual needs.

When Dr. James D'Adamo first studied naturopathy, he was taught that people, with their twenty-eight foot intestines, were intended to be vegetarians. Once he started his practice, he discovered that, after an initial improvement, not everyone thrived without meat. His observations led to a theory that linked diet to blood type. Just as certain diseases are more common in specific blood groups, dietary and exercise needs also correlate to blood groups.
Persons with Type O blood need protein - meat and dairy products- and plenty of strenuous exercise to burn it up: "If animal protein is not dispersed through physical exercise, it will cause unease and will adversely affect the internal organs. The body will use it against itself. This is not surprising. A boiler that is given fuel and frequently stoked will explode if the valve is not opened to release the energy produced." Unlike people with Type O blood, those with Type A are primarily mental beings. They need low energy food and light exercise. Type O finds that exercise helps clear the brain for decision-making, while Type A needs to "sleep on it." Type O, who needs exercise for optimal health, is basically lazy and finds it hard to get moving. Type A, on the other hand, often uses exercise to release tension and exhausts herself. Type A should gradually become vegetarian and use stretching exercise found in yoga and Tai Chi.
Between these two extremes lie persons with Type B blood, who are both physical and mental. They do well on a combination of meat and plenty of vegetables with strenuous and light exercise. Type AB lies between Types A and B, requiring less meat than Type B, but may not be as strictly vegetarian as Type A.

As Dr. D'Adamo used this system over the years, he discovered that some patients exhibited characteristics of blood types other than their own. One patient with Type O blood acted more like someone with type A; he could not tolerate strenuous exercise or dairy products. Dr. D'Adamo tested the man's blood again and found that while most of the blood remained unclotted (Type O), there was some clotting around the perimeter when contacted by the blue serum (Type A). Over the next five years, Dr. D'Adamo identified subgroups (Types Oa, Ob, Ao, Ab, Bo, Ba) and developed diet guidelines and vitamin supplement guidelines for each.

The D'Adamo Diet includes suggested "ideal" menus for each of the main bloodtypes and lists appropriate food and vitamin supplements for all of the groups and subgroups. In addition, Dr. D'Adamo includes a list of what to look for when shopping for food and advice on cooking and eating. The book also contains a chapter on vitamins and minerals, describing the use of each, signs of deficiency and food sources.

Realizing that telling a person to change her diet without guidelines can be overwhelming and a physical shock if done too quickly, Dr. D'Adamo includes a chapter that gradually guides each blood group to its appropriate diet. He gives five levels; each level has a list of goals to be reached over a period of weeks or months; for example, level I for each blood type includes eliminating processed and refined foods and suggestions on exercise. By the time an individual reaches level 5, she should be at the ideal diet and exercise program for her blood type.

In a section on remedies for various health ailments, Dr. D'Adamo gives dietary and vitamin supplement suggestions, which take into account blood type, to cure hypoglycemia. He also has a chapter on Candida in which he suggests starving the yeast organisms that live in the body by avoiding sugars, and starches that will become sugars, and to avoid any food that contains yeast. He also recommends yogurt, caprylic acid, and garlic to kill the yeast. He warns that Candida is a condition that may take months to clear up and may recur.

Dr. D'Adamo addresses his book, The D'Adamo Diet, to people who are interested in experiencing optimal health and who are willing to take responsibility for their own well-being. Dr. D'Adamo's experience in correlating foods,

supplements, and exercise to blood groups makes the book useful to doctors who use diet in aiding their clients to health.

A:

Eat Right 4 Your Blood Type

Your ABO blood type has significance far beyond its use as a means of determining who can give blood and receive blood from whom. Conventional medical practitioners don't generally pay attention to blood type beyond transfusions, except to acknowledge that people with type O experience three times the normal rate of ulcer.

What makes you A, B, or O is chemistry that goes far beyond your blood: It's throughout your tissues; it lines your digestive tract. It's in your serum; it's in your semen and in your saliva. Its presence plays a critical role in how your body distinguishes self from non-self, a fact which has far reaching implications in terms of immunity, inflammatory responses, and a host of factors related to your health status.

History of the Discovery

James D'Adamo, Dr. D'Adamo's father and also a naturopath, was working in the 1950's in a medical lab when it occurred to him that blood type might give him a clue as to why some people he observed did very well on spa diets while others fared very poorly on spa diets. Blood delivers nourishment to all tissues, he reasoned, and decided to investigate the relationship among blood type, diet and health. What the D'Adamos have come up with since the original illumination is a body of data that goes far beyond the two ABO blood type facts available to their conventional counterparts: that type A gets more stomach cancer and type O gets about three times the average rate of ulcers.
Through their research the D'Adamos have amassed data both on trends within the blood types to malfunction in certain circumstances but also on how to create circumstances to blood type-specifically enhance health.

Blood typing of 30,000 patients confirmed that type O people generally do well on a highly carnivorous diet, while As do not. Examining records for the 1940's and 50's to learn who gets sick from what and what the blood type distributions are, Dr. D'Adamo established that duodinitis and gastric ulcers are higher in O. Os have higher stomach acid. Also, rates of aplastic and pernicious anemia, gastric cancer, atrophic gastritis - all diseases associated with lower stomach acid - are found consistently in type A. Cirrhosis of the liver and diabetes are more common in A. Cancer of the colon, breast, lung and pancreas are more common in A and AB, while a variety of odd viruses are more common in B. Auto-immune, inflammatory, and "itis" diseases, however, are more often seen in O.

Using the system in his practice over the years, it emerged also that some people secrete their blood type in to their secretions, while others do not. You could be an A, A secretor, or A non-secretor. It's a separate gene and this is also associated with an assortment of health applications.

Continued research in cooperation with Bastyr College yielded that there are significant associations among blood type and anthropology and how foods were introduced into the human diet. Dr. D'Adamo has also researched the relationship between blood type and food-derived chemicals called lectins, which are agglutinating substances. Think of them as molecular Velcro.

History of Blood Types

Type O

It all started with O ("think Old"). O is not a true blood type. The cells contain no antigens. Os make antibodies to the other types, a factor in why Os tend to get more auto-immune disorders as there are substances throughout nature that have blood types. O is more common among older, aboriginal populations that haven't been disturbed. In certain native American populations it reaches 99% concentrations. These people are digestively built for high protein, meat based diets. This type of blood emerged about 170,000 years ago when humans had made a transition from scavengers to hunter predators. Over close to 100,000 years humans hunted in packs and decimated the global population of slow, large game, eating largely meat diets and adapting digestively to the food source. Briefly then, O, is intolerant of outside substances; it provides good protection against infection and malignancy but has a predilection for inflammation. Os have large amounts of clotting inhibitors so they have naturally thinner blood. They are more prone to arthritis, allergies and auto-immune disease. These people did not evolve on grains. Their insulin receptors and thyroid metabolism don't work well in a diet full of the agglutinins in grain. This demonstrates why dieters can't simply focus on caloric intake. One of the classic paradoxes of cardiovascular medicine is: Why don't those Eskimos, who are not on the Orrnish Diet, get heart disease? They don't grow vegetables. It is no surprise that 99% of them, like all ancient peoples, have type O blood.

Type A

About 25,000 years ago, blood type A started to emerge in large numbers. The gene had been there, but conditions did not favor it emerging in large numbers until the Neolithic revolution when human populations started to settle in agricultural settings and cities. Type A lost a lot of stomach acid ability compared to O. But it gained enzymatically the opportunity to maintain a level of alkalinity in their intestines. As do better on the type of diet available to people who lived in cities. As are also known to better tolerate the diseases of city dwelling like plague, small pox, cholera, dyptheria, all known to be more problematical for type O. Their blood contains an A antigen and contains antibodies to type B. A evolved to tolerate more that was out there but over compensated.

Type B

Only about 9% of the American population is type B. Anthropologists consider it an eastern blood type. Its prevalence diminishes as you go west and B is believed to be present in Europe only as a result of the Mongolian invasion of 2000 years ago. This blood type is believed to be an adaptation to dwelling in high altitudes. B has antibodies to A. They are largely omnivorous, although their food choices are somewhat idiosyncratic. They do well on turkey but not on chicken as chicken contains a lectin that agglutinates B blood.

Type AB

AB represents only about 2% of the population and is not in the evolutionary sense a blood type but rather the results of A and B populations intermingling. They have A and B antigens but carry no blood type antibodies and are universal receivers of transfusions. There is a known higher propensity for malignancies among ABs, which makes sense if you think of blood type as the guest list which welcomes A-like and B-like substances into your body. ABs have life a little harder because food reactivity includes foods from both the A and B lists. Certain types of food, however, like tomatoes, agglutinate all the blood types, but for some reason ABs negate the effect and can eat them.

Your Blood Type is Your Guest List

Your blood type is like a guest list that your immune system uses to identify other things with blood types in nature and determine whether they will be welcome in your body. If, for example, a virus enters your system, one of the first things your body will do is determine "is this my type?" If it is, the organism gets friendlier treatment than if it is not, in which case the immune system kicks in to get rid of it. Over time, parasites, viruses, bacteria, and fungi have taken advantage of this and mimicked blood type, as witnessed by the fact that there are whole series of infections that are blood type specific. For example, giardia is much more prevalent in As because it's an A-like organism. Many of the common cancers are A-like and more welcomed by and therefore threatening to Type A. Dr. D'Adamo views the evolution of B as a response to compensate for A's vulnerability to the many A-like organisms in nature. The good news is that, equipped with good information, you can blood-type specifically enhance your health.

Other Points of Interest

Type A is most negatively impacted by the average American diet. These people are designed more for a vegan diet using soy protein. A can compensate for its vulnerabilities by making soy the predominant protein source. The power of soy protein in type A is that 13% of the dry weight of tofu is "molecular Velcro" that soaks up A-like cancer cells that are trying to look like you. It has the ability to distinguish between you and something that is trying to look like you. It is interesting to note that the only Eastern culture with significant levels of type A blood is the Japanese, who are known to have a high incidence of smoking but a low incidence of prostate and breast cancer. They are the largest per capita consumers of soy products.

Blood type is considered in Japan to be an attribute of personality, and job applications even ask you to name your type. There are probably evolutionary reasons for this. Os are considered very purposeful people, righteous and ethical. As are thought to be visionary and detail oriented. Bs are thought to be balanced, inherently networking types, wonderfully organized. And ABs are thought to be compassionate.

One more point on blood type dieting: Lectins are the key to food allergies. You can save yourself a lot of food allergy testing by paying attention to which foods are right for your type.

Beyond blood type, it's very useful to know if you're a secretor or a non-secretor. A practical application of this is found in the practice of giving antibiotics to certain people before dental work. Even as a naturopath, Dr. D'Adamo noted he could support the use of antibiotics for a non-secretor because non-secretors can get terrible complications from strep in the form of heart and kidney problems. The most interesting thing about being a non-secretor is that it makes you a good candidate for alcoholism. And there is good documentation to show that the same people are the most likely to get the cardiovascular benefits of alcohol. One wonders if the drive to alcoholism might be related to the body's desire to protect itself from cardiovascular disease.

In ancient times you could go see a physician who was good at diagnosing, but he was not particularly valued. The valued physician was the prognosticator, the one who could tell you what you were going to get wrong with you and how to do something about it. Now we can use blood type and apply this ancient principle in combination with the wealth of information we have available today and come up with corellations between disease associations and the observed effects of the wrong diet for a particular blood type. The anthropological data in regards to the introduction of each blood type correlate with the introduction of the new food groups. There's the lectin and agglutinin connection. There's the reactions between the antibodies you have to other blood types with regard to the viruses you allow in to your body or foods that look like one blood type or another. There's the ability to explain the nutrition paradoxes and the opportunity to identify foods to be emphasized, not just those to be avoided. People don't get healthy when you only tell them what to avoid, you have to tell them what they should eat.

A:

EATING ACCORDING TO YOUR BLOOD TYPE: A BLOODY BAD IDEA

Eat Right 4 Your Type, a book by Peter J. D'Adamo (G.P. Putnam's Sons, New York), proposes that there are 4 different ideal diets, one for each blood type: A, B, AB, and O. By following the diet that is "right 4 your type," D'Adamo claims, you can lose weight, cure ear infections, fight off cancer, heal yourself from Chronic Fatigue Syndrome, and much, much more.

The advice is to eat like our prehistoric ancestors supposedly did. For instance, declaring type Os descendants of carnivorous hunters, D'Adamo urges them to load up on meat but to stay away from grains and beans. He calls the original type As "peaceful farmers" and therefore advises all type As to eat a vegetarian diet.

Unfortunately, he has his blood typing all wrong. "It is a fallacy even to speak of 'original' type Os or 'original' type As because blood types did not originate with humans," explains Stephen Bailey, PhD, a nutritional anthropologist at Tufts. "They came on the biologic scene long before humans did. Furthermore, there is no anthropologic evidence whatsoever that all prehistoric people with a particular blood type ate the same diet?

Nonetheless, D'Adamo has come up with 16 different food groups, further divided into "Highly Beneficial," "Neutral," and "Avoid" foods depending on what blood type you are.

But they're really just guides to low-calorie diets-some days' plans dip as low as 1,000 calories-with odd menu plans. Type As are advised to avoid eggplant, olives, peppers, and tomatoes, to name just a few forbidden foods. Type Bs are encouraged to stay away from bagels and peanut butter. Foods D'Adamo deems beneficial are just as odd. Snails are suggested for type As, while type ABs can look forward to tofu sardine fritters.

Not surprisingly, the author speaks of his "work" and his "research" throughout the book but doesn't reference a single study that he has published in a scientific journal. In fact, D'Adamo's "work" appears to consist entirely of anecdotes he has gathered from caring for his "patients" (he's not a physician) and of articles he has published in a non-peer reviewed journal that he himself founded and publishes.
