Category: Blood Type Diet
Had a rather relaxing week in Jamaica. Beautiful weather and friendly people. It was nice to just sit around a pool and read something besides computer or medical textbooks. I confined my reading to mostly ancient history.
Since being back I've be messing around with Facebook, the social networking website that everybody seems to be on nowadays. I think it is much better than MySpace, since it does not allow you to alter the appearance of your pages all that much. I always found MySpace rather unsettling, what with all the blaring colors, poor quality videos and music on people's sites: most of which I prefer not to see nor hear.
When Facebook does allow you alter stuff, it is mostly in the form of applications ('Facebook Aps') which run inside of Facebook. Programming these applications can be perplexing, since Facebook uses may proprietary pseudo-languages and interfaces -and the documentation can be spare at times.
If anyone has been to my Facebook page recently, they'll already know this, but for those who have not, my first application called 'Is it right for your blood type?' is now up and running.
Of course, you'll have to be on Facebook to use it, but they make it very easy to join and it is a rather safe place overall.
The app is based on the TypeBase Program on this website, but also allowing you to search by foods (soy, celery, beef, etc.). You can add the app to your profile sidebar which then allows others to join and use it as well.
Like golf, learning new computer languages is occasioned by a rather irksome awkward stage, but I think I'm finally heading out of it. if you do use the app and find a bug please drop me a line and let me know.
In addition to the Facebook work this morning was spent doing a half-hour interview for Singapore radio with a charming young host. While on the radio I opened some recent mail and was pleased to receive three spanking new copies of the 'Allergies' book, which has just been translated into Arabic. It is wonderful to marvel at just how global this eating philosophy has become.
I think yesterday’s Grand Rounds at The University of Bridgeport went well. As seems to be the case more and more these days, I had a surfeit of material; much more than I could contain within the two hours allotted --even though I had limited the lecture to only the first part of standard presentation (‘Adjusting People to Genes’).
Dr. Natalie Colicci, my associate over at the D’Adamo Clinic and an alumnus of the Naturopathic Program at UB, thought it was a success and the students (third and fourth year) paid seemingly rapt attention.
It was nice to also see a few of my associates from bygone days including Dr. Eugene Zampieron, Dr. Leigh White and Dr. Ginger Nash-Wolfe.
UB/ND’s Dean, Dr. Guru Sandesh Singh Khalsa and Associate Deans Dr. Elizabeth Pimentel and Dr. Christina Arbogast Woolard have done a wonderful job getting this program up and running. After the lecture Dr. Arbogast gave us a tour of the teaching facility and the University Clinic, which was most impressive. I enjoyed meeting many of the students, administrators and faculty and was pleased to see that a generally positive, professional and pleasant tone permeated the facility. The UB Clinic sees a lot of economically disadvantaged families from the Greater Bridgeport area --many of whom would not normally be able to afford naturopathic health services on any sort of limited budget.
Dr. Arbogast and I talked about my doing some type of special shift in the Clinic, where students who were interested in my research could receive some in-depth training. I’m sure we’ll revisit this sometime in the future, but the idea of teaching in a clinical environment did seem very attractive to me, if indeed a new obligation would appear to be the last thing I need in my life right now.
They asked me to come back in April to finish up the lecture and perhaps delve into some of the epigenetics material as well. I was surprised to hear from the students just how many were already registered for the IFHI 2009 Conference.
How refreshing was this reception as compared to overall apathy and lack of acceptance I’ve received at Bastyr University, my own alma mater. One of undergraduates recently wrote to tell me that during one of the nutrition classes he attended, the instructor proceeded to describe my work with blood groups as ‘unscientific’ and followed that assertion with a description of the ABH Secretor System which my friend described as ‘not having one single correct fact .’
How different is this Bastyr University from the school I knew and loved.
Gerhard Uhlenbruck, everybody’s favorite lectinologist, recently wrote to let me know that he had penned the forward to a new book ‘Micronutrients’ by Uwe Grober (MedPharm) and kindly included a copy. Very nice book which I anticipate will get some thumbing-through over at the D'Adamo Clinic.
A recent review article on ‘Dietary Lectins as Disease Causing Toxicants’ written by Rabia Hamid and Akbar Mascod (Pakistani Journal of Nutrition 8 (3) 293-303, 2009) referenced three of my works in its citation list.
The second sentence in its abstract just about says it all:
It is now well established that many lectins are toxic, inflammatory, resistant to cooking and digestive enzymes and present in much of our food.
Maybe I’ll send a copy over to Andrew Weil.
A recent question posed to an internet dietician Mary Hartley sparked some outrage over on the www.dadamo.com message boards and got me thinking:
Is there any truth to the diet based on blood type?
For example, O blood type should eat more protein and AB blood type should eat more veggies.
The Blood Type Diet is outlined by Peter D’Adamo in Eat Right 4 Your Type, a diet book that has been a bestseller for over 10 years. Mr. D'Adamo asserts that your blood type is the key to your immune system, and by eating particular foods according to your blood-type, you can lose weight and prevent diseases, such as cancer, asthma, arthritis, diabetes, and others. But truthfully, there is no scientific evidence to back the authors claims, and the diets recommended for some blood types could produce nutritional deficiencies. The Blood Type Diet is just another fad diet.
Many dieticians embrace and use the research behind the Blood Type Diet, so it is not a complete and absolute truth to claim that registered dieticians (RD) know almost nothing about nutrigenomics and genetic based nutrition. However, based upon a series of interviews conducted in Holland among Dutch dieticians, it's not far from the truth:
Based on the analysis of 51 face-to-face interviews with Dutch dietitians in April 2006, it can be concluded that awareness and knowledge on nutrigenomics is low. Almost half of the interviewees had heard of nutrigenomics and nutritional genetics, but most could not explain what either were about.
Clients of more than half of the interviewees bring up the topic of heredity or family history during consultations in regard of nutrition-related diseases such as weight and diabetes. Clients almost never ask questions related to genetic testing but, if they do, it is in the context of hyper-lipidemia, hyper-cholesterolemia and other metabolic disorders.
More than half of the dietitians thought genetic testing would be relevant for dietetic practice. Most, however, experienced difficulties with identifying the practical implications of nutrigenomics. They expected nutrigenomics to offer opportunities for dietetic practice through tools for creating more personalized or individual dietary advice and prevention of diet-related ill health. Some dietitians expressed concerns about cost, the current lack of evidence, and the affect on clients’ attitudes whilst other felt they knew too little to identify their concerns.
In line with these concerns, there is feeling that nutrigenomics is not relevant to dietetic practice because of a lack of evidence, anticipated costs of testing, and the existing potential for treatment without genetic testing.
When I read these critiques from people who are supposedly experts I simply marvel at the degree of self-assurance they display despite what appears to be a complete ignorance of the subject. There is enough science behind the use of blood type as a dietary determinant to choke a horse; maybe two or three horses. However, if you don't like the conclusions (or more likely don't like who or where they came from) go ahead and criticize the science. That never fails to buy a bit of time.
I also get a bit skittish when someone who is trying to convince me of something starts their sentence off with 'Truthfully...'
The line about the diets producing nutritional deficiencies is complete twaddle. There is no proof of that whatsoever. I challenge Ms. Hartley to back up her assertions with some sort of evidence, or lacking that have the courage to retract this ridiculous statement.
Reminds me of the quote by Upton Sinclair:
If is difficult to get a man to understand something when his salary depends upon his not understanding it.
Speaking of fad diets, many dieticians still cling to the low-fat (or should I say 'fat-phobic') fads of the 1980's. There is perhaps perverse justice in a vignette I recently read in David Stafford's terrific new book Endgame, 1945. Stafford writes that after the outcry against the Nazi euthanasia program, the experts merely moved their lethal expertise away from gas to starvation:
The asylums and hospitals reverted instead to the murdering of the handicapped through lethal injection and deliberate starvation. The director at Kaufbeuren, Dr. Valentin Falthammer, was an especially keen and energetic supporter of the program, and proudly introduced a carefully crafted fat-free diet that guaranteed death to his patients and economized on pharmaceuticals. The death rate rose so high that local authorities forbade the ringing of church bells at funerals, so as to not alert the local population.
Like Peter Gabriel said three decades ago:
It's only knock and know-it-all,
but I like it.
Spent the weekend in Phoenix/Scottsdale where I lectured to the Arizona Naturopathic Medical Association. Nice crowd; surprising to me was the fact that MDs outnumbered NDs at the morning professional session. Had way too much material. The professional lecture was supposed to last four hours, and by midpoint I realized that I actually had about nine hours worth of material, forcing a truncation which certainly had nothing to do with any lack of science.
Happily, this probably means that my presentations for IfHI 2009 are already complete.
Here is a short film about the epigenetic landscape that I made for the lectures. Enjoy.
New research shows that sugar deposits may be the major cause of skin aging.
Skin science appears to have caught up with the humble sugar molecule. Wrinkles, sagging skin, and pigment deposits may stem less from the sun and more from one-way sugar molecules that we make as part of the aging process but cannot remove. With no small amount of serendipity, scientists call these wrong-way sugars ‘AGE molecules’ (the AGE stands for 'Advanced Glycation End-products').
AGE molecules are all around us, and often taste pretty good: Any time we brown an onion or caramelize sugar we are making AGE molecules. However, when you make these molecules under your skin, you’ll probably find much less to like about them.
Unlike most other complex sugars, AGE molecules are not easily removed from the body (Just think back to a time you tried to clean burnt sugar off of a piece of crockery!) And because they stay in place for years, the immune system can react to tissues they deposit in, causing inflammation, damage, and aging.
AGE molecules: Good on marshmallows, bad on people.
NAP recently released the next three D’Adamo Genoma Skin products, which now expands the line to four products:
The Day Light Face Crème is the original formula. We’ve has virtually 100% customer satisfaction with the product, including unsolicited comments from three users that it was the only product that worked on their facial rosacea.
To this base formula, I’ve added an AGE (Glycation inhibiting) toner, a rich night crème and a tissue cleanser that uses a few very interesting botanicals.
For the rest of the month, at my request, NAP is offering the complete set of four products at a savings of 50%. I asked that they try to do this so that as many people as possible can try the line. If you are looking for a great skin care line at an unbelievable price, either as a holiday gift for someone or even yourself, you might want to look into these products.
However, do it before December 31, 2008.
As I've been tinkering with this new blog software, I've become acutely aware of the importance of skins and themes. For the uninitiated, a theme (the more 'proper' wording) or skin (what everyone calls them) are a set of variables that a programmer often adds into a program that allows people to change the appearance of the program in ways that make it more personalized. For example this blog uses a variation of a skin called 'Nautica', which give it a rather pleasing blue palette. To get a better idea, you can browse the various skins for the blogging program Wordpress.
As I went along I began to see the GenoType characterizations as skins of a sort. If blood groups, secretor status an whatnot are the body, then the GenoTypes would be the choice of wardrobe.
For example, look at this graphic:
If we compare the basic type A characterizations and diet, we would see that type A has problems from a mostly tolerant immune system, a greater risk of heart and artery problems, and a greater risk of cancer. Reasonable enough, since that is what the research literature suggests. Type A's have less p53 tumor suppressor activity and their arteries are more prone to inflammation.
However, under simple blood type association, there is really no prioritization of this information.
If we look at the GT3 Teacher program we would see that the diet is skewed more towards cancer protection. It is in the GT3 Teacher that the p53 tumor suppression susceptibility winds up. GT5 Warrior on the other hand, seems to carry the arterial risk; probably because of the two, they are the more thrifty type. Thus if you GenoType as a blood group A Teacher, you will be wearing the 'cancer prevention skin.'
Technically if you are type A you could wear several skins, however if you GenoType as a Teacher, the Teacher skin will be the most therapeutic for you. Same with type O: You might need the 'metabolic syndrome' skin (GT2 Gatherer) more than the 'catabolic inflammatory' skin (GT1 Hunter).
Ditto for the B's and AB's.
Hopefully this will help folks see how values can change when one migrates from the BTD values to the GTD system. Somewhere in the allowable GenoTypes for people with type A blood, there will be that old BTD avoid, however, if it is not in your new GenoType values (or if it flipped to being actually beneficial!) it is because its BTD avoid status was less relevant than the benefits it provides under your new GTD skin.
