I'm a Type O neophyte to ER4YT. Noticed oat meal, oat flour and pepper in your recipes for Type Os but found those items on the "Avoid" list so I'm confused....
This was a typographic error, and a lack of communication between myself, Catherine and Dina the recipe dietician. In a state of health, type O's can use oats, which should be considered neutral: This is what Dina was proceeding on. However, if you are type O and have either an inflamatory condition of the digestive tract or joints (such as colitis or arthritis) or you are using ER4YT to lose weight, you should continue to avoid oats: This is what Catherine was proceeding with. Otherwise it is fine.
QUESTION: Why do type O non secretors have guidelines for less oil than secretors? What is it about being a non secretor that makes us less capable of handling oil?
ANSWER: ABH non-secretors have lower levels of fat-busting enzymes (intestinal alklaine phosphatase) than ABH secretors. They also have lower levels of a variety of lipases (more fat busters) and brush border hydroxlases (again, involved in the transfer of fats broken down in the intestine into the lymphatics.)
Independent of ABO blood group, ABH non-secretors have lower alkaline phosphatase activity than ABH secretors. It has been estimated that the serum alkaline phosphatase activity of non-secretors is only about 20% of the activity in the secretor groups. (1-4)
The intestinal component of alkaline phosphatase is involved with both the breakdown of dietary cholesterol and the absorption of calcium. The differences in intestinal alkaline phosphatase are almost exclusively related to one fraction of the intestinal alkaline phosphatase. Normal molecular mass intestinal alkaline phosphatase (NIAP) is present in the serum of both secretors and non-secretors regardless of ABO blood group. However, the high molecular mass intestinal alkaline phosphatase only appears in serum of Lewis (a-b+) blood group secretors. (5)

QUESTION: I am a 16 year old vegetarian and blood type A. I follow the type A diet from your book, and have been doing so for about 10 months (been vegetarian for over 4 years). My question is can you recommend anything for acne?
ANSWER: Proper stress reduction is important for type A's, as one of their prime focal points of stress lies at the adrenal level.
Since stress can aggravate acne (probably due to enhanced adrenal activity, and greater sebum production.) Some ideas include:
Zazen meditation or similar meditation/ yoga techniques. These can help lower cortisol and help break the stress cycle.
Practicing alternate nostril breathing. exercises leads to deep relaxation --probably because of its effects on sympathetic/parasympathetic balancing. The benefits of this relaxation become apparent in your daily life, and you find yourself calmer and more peaceful. You may also have a great deal more energy than before.
Group A in general is associated with a 'constant and malignant' carrier state with regard to Staphylococcus aureus, a bacteria associated with acne.
Many acne sufferers have a mixture of microbacteria and yeast on their skin, which can help trigger inflammatory reactions leading to pimples, etc. Tea tree oil has been studied and found effective in treating acne. I've had good results with recommending Paul Mitchell brand Tea Tree Soaps.
There is moderate evidence that oral zinc supplements may be somewhat effective as well. A low dose (15mg daily) may be prudent.
QUESTION: I live in France and frequently recommend your work to French friends. I unfortunately can no longer find your French site, nor a link to it on your page. The medical profession here can be somewhat hidebound; having access to your information in French makes a difference to people suffering from what amounts to conditioned scepticism. Does the site still exist? Much thanks for your answer!
ANSWER: We will soon add a 'links page' from the main page, which will feature a few blood type based websites, including the great French mirror siteABOVIE.COM
QUESTION: My hair turned very white 14 years ago when I had my children. After being on the A diet for 4 months (I have been a vegetarian for 2 years) my hair is turning very dark again. Can you explain this? I have been totally dedicated to the diet - mostly HB. I am thrilled!
ANSWER: We don't know why hair turns gray. We know that there is melanocyte (pigment cell) dropout or there is depigmentation of the melanocytes. But we don't know exactly why. It could be related to vitamin D because in certain vitamin D resistant syndromes hair growth stops or it is thin and often gray.
Graying hair in young women is often associated with osteopenia (bone thinning) and/or thyroid problems. Vitamin B-12 deficiency, anemia or viruses can cause gray hair to appear as well. There is also the phenomenon of "going gray" due to a shock or fright but is not well documented and is hard to explain physiologically.
I can assume that the biologic demands from your pregnancies, perhaps in conjunction with nutritional deficiencies or a thyroid shut-down, may have prematurely turned your hair white. However, this may not have been what your genetic 'timeclock' had you coded for. Following the diet, blood type A which maximizes absorption of key micro-nutrients, and lectin avoidance (which can be thyroid-sparing) may have been just the ticket to get your melanin production back into synch.
I have been on your diet for 1 1/2 years now, and trying to convince others to try it. A lot of people ask me, "How can it be that wheat isn't good for anyone? Hasn't it been a staple in man's diet for thousands of years?"
Wheat as we know it in the millennia of this era is not the same as it was at the very beginning. The genetics of wheat show that its development is very complex. Today's grain has developed from three naturally occurring groups of wheat. Through natural crossings, mutations, and natural selection these have evolved into all the many varieties of wheat grown worldwide.
In essence, the 'hard wheat' that we eat nowadays has a protein content as high as 13%, versus the more ancient wheats which had a protein content of, at most, about 2%. Increasing the protein content has had the effect of making wheat a viable source of protein for many people around the world, but has also increased the allergenic (gliandin, gluten and lectin containing), pro-inflammatory and metabolic-blocking portions of the plant almost seven-fold.
Aside from the under-investigated metabolic effects of wheat lectin, classic hypersensitivity to wheat is found in many infants and adults. Reactions are often localised in the GI tract. In a study of asthmatic patients, 46% (children) and 34% (adults) were found to have IgE to wheat as tested by Pharmacia & Upjohn, Diagnostics CAP System. In another study, specificity for wheat allergen using the same system was 98%. Wheat allergy was found to cause a persistent food hypersensitivity in atopic dermatitis patients (75% remained intolerant). In 102 grass-pollen allergic children, 12% were found to be allergic to wheat.
QUESTION: My best friend a Type B Pos, received breast implants about 10 years age. She has had to have this major surgery repeated (4) times. Her body "keloids" incredibly actually causing movement/displacement of the implants. This time she is on your Surgery A & C suggestions in ER4YT. Any other suggestions? Surgery yesterday. Time is of the essence. Thank you.
ANSWER: I would advise your friend also consider:
1. Bromelain (pineapple enzyme fraction) 500mg capsules: 1-2 capsules every 3-4 hours
2. Centella asiatica (Gotu Kola): The usual dosage of gotu kola is 20 to 60 mg 3 times daily of an extract standardized to contain 40% asiaticoside, 29 to 30% asiatic acid, 29 to 30% madecassic acid, and 1 to 2% madecassoside. Be patient, because gotu kola takes at least 4 weeks to work. For the prevention of keloid scars, the herb is usually taken for 3 months prior to surgery, and for another 3 months afterwards.
3. Horse chestnut (Aesculus hippocastanum): The most common dosage of horse chestnut is 300 mg twice daily, standardized to contain 50 mg escin per dose, for a total daily dose of 100 mg escin.
QUESTION: I'm a type B. Dr's Eades' (Protein Power) say that flaxseed oil is something to avoid. What's your take on the recent literature about this?
ANSWER: Apparently the Eades have changed their minds on flaxseed oil, as per this quote from their website:
"Since we wrote the section on eicosanoids, we have had brain transplants. (Unfortunately when Mike wrote that section he had fallen under the evil influence of our good friend, Barry Sears.) We, too, now believe that flax seed oil can be valuable and we take it ourselves and use it on many of our patients."
Essential Fatty Acids (or EFAs) unlike many other nutrients cannot be manufactured by the body and must be provided in the diet. The two essential fatty acids are often referred to by the name of their general category: linoleic acid is an omega-6 fatty acid and therefore oils high in LA are often referred to as omega-6 oils; alpha-linoleic acid is an omega-3 fatty acid and therefore oils high in ALA are often referred to as omega-3 oils. While both categories are crucial to good health, they must be present in the body in proper balance with each other as well as in proper amounts. Most researchers describe a healthy balance of omega-6 to omega-3 oils as anywhere from 1:1, to 3 or 4:1.
Some facts about flax:
Other, more anecdotal benefits include the improvement of arthritis, multiple sclerosis, immuno-suppression, psoriasis and eczema.
The average person probably doesn't have to worry about getting enough omega-6 oils unless he or she has a specific health problem: but almost everyone should consider bolstering his or her intake of omega-3's. Adding at least one tablespoon of properly processed flaxseed oil to our diets on a daily basis can significantly add to the proper balance because flaxseed oil has a 1:3 omega-6 to omega-3 ratio.

QUESTION: Your website's new databases are the ultimate food reference tool! I've been browsing the "Frankenbase" lists and have been astounded by the ubiquity of genetically modified foods in brand-name products. Are there a few, widely used GM food sources (such as wheat, corn and soy) that are being included in most of these products? What might these "common denominators" be and, do you advise against eating them even though they may be "Neutral" or "Beneficial" for one's bloodtype? Thanks again!
ANSWER: FRANKENBASE is a database listing prepared foods known to contain genetically modified ingredients. Whereas soy and corn are now extensively distributed in the food chain and may well be impossible to completely avoid, at least you can look for prepared foods that do not contain GM ingredients and choose to support manufacturers who do not include them in their products.
STUDY: Heterogenicity of the immune response to antigens of muscular and interstitial connective tissue of the heart in patients with rheumatic diseases. II. Association with ABO antigens
JOURNAL: Vestn Akad Med Nauk SSSR 1989;(9):80-5
AUTHORS: Motovilov AA
ABSTRACT: Antibodies (Ab) reacting with myocardial fibre sarcolemma (SL) and interstitial connective tissue (ICT) were determined by means of indirect immunofluorescence technique. The Ab level was found to be dependent on the ABO. Subjects having O and A blood groups are most potent ICT Ab producers, while those with B group, the weakest. The inflammatory process activity exerts varying effects on the level of ICT and SL antibodies depending on the ABO. The ICT Ab level reduction and SL Ab level elevation in maximal inflammation activity were revealed only in O and A blood groups, but not in B-group patients.
COMMENTARY: This study looked at the amount of antibody produced against heart muscle and connective tissue in individuals with rheumatic heart disease. Rheumatic heart disease is a complication of rheumatic fever which results from an untreated strep throat, and which can damage the heart valves, causing them to fail to close properly or not open enough. Group O and A subjects had higher levels of antibody production against connective tissue. This appeared to be directly correlated with the level of inflammatory activity as well. This was lower in group B subjects. Interestingly, the author speculates that the presence of heart muscle fiber antibodies is believed to be a risk factor of cardiac disease, but only in O and A blood group patients, as it correlates with the level of inflammatory activity in the heart muscle in these groups.
QUESTION: How do I combat "white coat syndrome" where my blood pressure really increases when I go to the doctor? When I take it outside of the doctor's office, it is in the normal range, and I can even feel myself calm down and my heart rate become more normal 10 minutes into the office visit. But it seems that the nurses measure the BP right away when I first come in and am nervous. I have been following your diet, walk at least a mile almost every day, don't smoke, am losing weight, seldom drink and use only decaf beverages, etc, but I hate getting so nervous that my blood pressure reading goes out of the normal range.
ANSWER: One of the best, non-drug treatments you can do for yourself is the old Ayurvedic technique Alternate Nostirl Breathing. Five to ten timunyes of the techniqure priot to the doctor visit (perhaps while waiting for the doctor to come in the room) will work wonders.
QUESTION: How long should someone take collinsonia for chronic sinus problems? What is daily dose recommended?
ANSWER: Collinsonia canadensis ('Stone Root') has its effects on the vasculature of the sinus cavity, increasing the tone and strength of the veins (which it also does for the throat, liver and hemorrhoidal veins as well). Because it does not possess anti-histamine like actions, it is safe to take for long periods of time. Results vary from person to person, but most people see improvement within 90 days. Here is a link to the NAP information piece on Collinsonia.
My son has Crohns Disease, and is taking Pentasa (Mesalamine). He is blood type O. We got the multi vitamin for type O and he did very well. But the store stopped carrying it. I am happy to find your site. My question is this. The Pentasa is very hard on him and the doctor told him it was making him lose his hair. Is there something else he should be taking in your line of products?
Pentasa tends to interfere with PABA and folic acid metabolism, which can predispose to increased activity of yeast on the scalp. This can result in destruction of the hair follicle and loss of hair.
Your son can make a very effective hair rinse out of oil of rosemary, glycerine and oil of bergamot. To eight ounces of distilled water, add 15 drops oil of bergamot, 1 tblsp glycerine and 10 drops oil of rosemary. Have you son apply this to the scalp before bed, accompanied with vigorous scalp massage.
To this procedure I would also add taking the B vitamins biotin (8mg daily) and folic acid (2-3 mg daily).
QUESTION: I am a Type A and have been doing your Blood Type Diet for 8 months (fairly religiously) with huge benefits. I note that avocado is a neutral food from the fruit/vegetable list. A new product on the market here in New Zealand is cold pressed avocado oil which is delicious - is this a good thing for an A Type? Personally I find it a rather nice substitute for olive oil especially on salads and steamed vegetables.
ANSWER: TYPEbase II list avocado neutral for blood group A and blood group O non-secretors. The oil is not atherogenic (causing excessive artery plaque formation) so it would rank as 'neutral' for blood group A. Note: since avocado can be problematic for the other blood groups, they should consider avocado oil an avoid no different than avocado. Until further elaboration, group O non-secretors should consider the oil an avoid.
QUESTION: Along with my Type A diet, A Lifestyle, my snail lectins, calcium d glucorate, aromastat, etc. etc. for breast cancer recurrence protection, I have noticed a battle going on between the makers of I3C and DIM. One accuses the other of making aromatase enzymne increase which of course I don't want to do. Each says their product type is better? Trying to understand the physiology and get through their research both quoting medical journals. It is confusing. What is a girl to do?
ANSWER: Indole-3-carbinol is a phytochemical found in cruciferous vegetables such as cabbage. It shows great potential in preventing cancer, especially hormone-related cancers such as breast and prostate.
DIM (3,3'-Diindolylmethane)is formed naturally when I3C is broken down in the gut. So from I3C you get DIM (although from I3C you also get many other molecules as well.)
DIM is being heavily promoted in the 'longevity' magazines by one doctor, who has a patent on the ability to increase its absorption via the gut (tweaking DIM with d-alpha-tocopheryl polyethylene glycol-1000 succinate to make it absorbable.)
My completely subjective analysis:
1. I3C is more 'food like.'
2. I3C breaks down into many other compounds besides DIM, some of which may be more useful than DIM
3. The studies on DIM itself are not as compelling.
Supplement or stress dietary I3C over any claims about DIM's greater efficacy.
QUESTION: I am interested in the protein bars. I cannot find the iron content/amount in the information on the website. I have an iron loading disease and must know how much iron is in the product.
ANSWER: The recommended daily intake (RDI) of iron is 18 mg. Thus for each 50 gram bar:
The O bar (iron content= 8% RDI = 1.44 mg)
The A bar (iron content= 10% RDI = 1.80 mg)
The B/AB bar (iron content= 10% RDI = 1.80 mg)
QUESTION: I am Type O & am concerned with intkaking a lot of red meat. Based on the information I've read in ER4YT red meat should be consumed 3-4 times per week. I'm concerned with the disease's that are occuring such as Mad Cow Disease, high cholesterol, & obesity due to the fat content.
ANSWER: Because the risk of dying in an auto accident is about 10,000 times greater than getting nvCJD ('Mad Cow') by even eating meat in England.
From the CDC website:
The current risk of acquiring nvCJD from eating beef (muscle meat) and beef products produced from cattle in Europe cannot be precisely determined, and this risk in specific countries might not reflect the fact that cattle products from one country might be distributed and consumed in others.
Nevertheless, in the United Kingdom, this current risk appears to be extremely small, perhaps about 1 case per 10 billion servings.
In the other countries of Europe, this current risk, if it exists at all, would not likely be any higher than that in the United Kingdom, except possibly in Portugal. In the 12-month period ending June 15, 2000, Portugal had about half the reported incidence of BSE cases per 1 million adult cattle as that reported in the United Kingdom; however, Portugal has less experience with implementing BSE-related public health control measures.
Risk? Yes. High Risk? Probably not, and considerably lower in any country except the UK and Portugal, where because of stringent herd control measures it is quit elow already.
As far as fat content, well if you do read my books you'll know to buy low fat, hormone-free, pesticide free organic meat where the fat content approximates that of skinned poultry. Everything else is verboten.
QUESTION: Per this week's NIH meetings on the subject of Sjögren's syndrome, can you comment on the relation of Sjögren's to blood type (beyond its general auto-immune implications for O's) and the ER diet? My type-O father died of it, and his five middle-aged type-O daughters are nervously watchful about things like contact lenses, periodontic disease or numbness in toes. Thanks for your great answers on this board.
ANSWER: Sjögren's syndrome is a chronic disorder of unknown cause characterized by a particular form of dry mouth and dry eyes. This loss of tears and saliva may result in characteristic changes in the eyes (called aqueous tear deficiency or keratoconjunctivitis sicca) and in the mouth with deterioration of the teeth, increased oral infection, difficulty in swallowing, and painful mouth. There are many different causes for dry eyes and dry mouth. When they occur as a result of an "autoimmune" process, the condition is called Sjögren's syndrome, which usually occurs in middle-aged women and has prevalence in about 1 in 500 persons. Patients may also have inflammation of the joints (arthritis), muscles (myositis), nerves (neuropathy), thyroid (thyroiditis), kidneys (nephritis), or other areas of the body. Also, patients may have severe fatigue and disruption of their sleep pattern. Also, the blood of Sjögren's patients may contain antibodies directed against normal cellular substances such as nuclear antigens and immunoglobulins. Therefore, this disease is termed an "autoimmune" disorder to denote the apparent reaction of the immune system against the patient's own tissues
QUESTION: I am an American Indian, Type II diabetic, type 0, with diverticulosis which has caused severe constipation over the last six months. Nothing has helped.I bought you first book this week read it. No mention of what might help. I am desperate for relief. Please help me become a regular guy again. Thanks!!
ANSWER: Many people have small pouches in their colons that bulge outward through weak spots, like an inner tube that pokes through weak places in a tire. Each pouch is called a diverticulum. Pouches (plural) are called diverticula. The condition of having diverticula is called diverticulosis. About half of all Americans age 60 to 80, and almost everyone over age 80, have diverticulosis.
Though not proven, the dominant theory is that a low-fiber diet is the main cause of diverticular disease. The disease was first noticed in the United States in the early 1900s. At about the same time, processed foods were introduced to the American diet.
In general, following the type O diet, with emphasis on lots of beneficial fruits and vegetables, plus lean meats, can help regulate bowel function, especially if you make it part of a program that includes regular exercise.
Insoluble fiber binds water, making stools softer and bulkier. Therefore, fiber, especially that found in whole grain products, is helpful in the treatment and prevention of constipation, hemorrhoids and diverticulosis. Diverticula are pouches of the intestinal wall that can become inflamed and painful. In the past, a low-fiber diet was prescribed for this condition. It is now known that a high-fiber diet gives better results once the inflammation has subsided. A fine form of fiber is arabinogalactan derived from the larch tree. Because it is both soluble and insoluble it has more utility in diverticulosis, since exclusively insoluble forms of fiber can aggravate inflammation of the diverticula.
For some Type 2 diabetics, diet and exercise are usually sufficient to keep the disease under control, however you must see your doctor regularly and if you have any change of symptoms. Supplementing the diet with fenugreek (Trigonella foenum-graecum) seeds has been shown in clinical and experimental studies to reduce blood glucose and insulin levels while also lowering blood cholesterol. Adding several helpings of mushrooms to the diet may also help with managing type II diabetes, if the are allowable for your type. Finally, supplementing with the anti-oxidant flavones quercetin or rutin may help control diabetic complications in some individuals.
QUESTION: As an almost 5 year veteran of following ER I would like to say that I hope you will continue the message board because with out it MANY people (as made clear by their posts) would not follow thru with their blood type eating plan and find the success in their life. Even now I still get so much out of the information shared on the board... always something new to learn and inspire you towards following ER and keeping with it. Isn't that the point of good info?
Regarding the Board. I think you made the right decision--what were once favours are now obligations as the saying goes. The selfish part of me regrets it--became part of my morning ritual, always learned something. But, who needs the grief you were getting?-- especially when it distracts you from going after the prize--the work itself and healing.
ANSWER: No one discontinues a six-year project without the deepest of thoughts and feelings. Quite simply, it is a matter of personal choice. From an educational standpoint the usefulness of the message board format is limited. However, the site will be featuring several more 'Ask Dr. D'Adamo-like' daily columns that can educate in a more focused matter.
At this time I would like to thank all of the folks who made the ER-MB the great community it was. You know who you are.

QUESTION: I am Type O, & purhcased both the supplement list & Eat Right 4 Your Type BUT I am finding differences in the food lists! Ex: list for vegetables says cabbage & sauerkraut are neutral, and avoid cukes; book says cukes are neutral, avoid cabbage, and doesn't list sauerkraut! Same problem with green peppers! Also many other contradictions! What am I to believe???
ANSWER: It is because you have entered the Twilight Zone.
Well, no. In reality different books are in different stages of upgrade or complexity. For example:
First book (Eat Right 4 Your Type) was a basic synthesis of the concept. It had to make some judgements regarding homogenizing information if it was secretor status specific. If a food was deemed a more serious avoid for a non secretor than it might be as a neutral or beneficial for a secretor, then the non-secretor value was used.
2. Second Book (Live Right 4 Your Type) had secretor status differences.
and a very small number of food value changes, reflecting the advances in basic scientific knowledge.
2. The 'little books' (Food and Beverage Guides) Are a mass market book, very simplified, with largely just secretor guidelines and with a few of the altered values included.
