Study Links Blood Type and Fertility:
Scientists at Yale and Albert Einstein College of Medicine confirm 10-year-old
research of Dr. Peter D’Adamo
As nutrition has an overarching affect on health and hormonal stability, Dr. Peter D’Adamo makes nutritional recommendations unique to each of the four human blood groups to promote fertility and a healthy pregnancy.
In a study presented at the American Society of Reproductive Medicine Conference
in Denver, researchers at Yale and Albert Einstein College of Medicine measured
levels of a chemical called follicle-stimulating hormone (FSH) in 560 women undergoing
fertility treatments and found that those women with type O blood had chemical
signs linked to low egg numbers.
The control group had an average age of 35 and those with O blood type were found to have higher levels of FSH – almost twice the levels of women with the blood type A antigen. This is significant as high levels of FSH are thought to be an indicator that a woman’s ovarian egg reserve is diminishing – which can reduce a woman’s chances of conception once a woman reaches her 30s and 40s.
Although researchers at Yale and Albert Einstein College of Medicine could not identify a specific reason for this association, Dr. Peter D’Adamo
provided this insight, “A significant number of infertility cases are the result of immunologic hostility between a person’s blood type and the environment.”
Dr. Peter D’Adamo has researched the connections between blood type, genetics, and disease susceptibility for more than 30 years and supported his findings with extensive scientific documentation. In his book, Eat
Right for Your Baby, published in 2003, Dr. Peter D’Adamo discussed the vital connection between blood type and fertility, pointing out that, “Type O’s tend to suffer from hormonal and metabolic disorders, which are a major impediment to fertility.” As nutrition has an overarching affect on health and hormonal stability, Dr. Peter D’Adamo makes nutritional recommendations unique to each of the four human blood groups to promote fertility and a healthy pregnancy.
A Year in Review
Martha D'Adamo
Having looked back, I can now take a moment and look forward to our continuing growth as a concept and as an ever-expanding community. I am so grateful to all of you who share this journey into personalized medicine with us.
I am stunned by the rapid passage of 2010. I don’t know if this is a function of aging or of living a busy life, but I don’t recall any year that has passed as quickly as this one has. I have to keep reminding myself to take a deep breath and slow down as the year comes screeching to a close.
Helping me to slow down is the ability to look back and appreciate the moments – both big and small – that went into making the year as special as it was.
The
GenoType® Diet was published in paperback
as Change
Your Genetic Destiny. Throughout the year,
we saw an ever-growing awareness in the media about the role that
fetal development and epigenetics play in health and wellness. This
underscored yet again how ahead of the times Peter is with his research.
Genoma
Security™ was launched. Probably one of my all
time favorite products (along with Hytrax™ and Carob
Extract™),
it is a “work horse” product which supports a balanced
immune response. It can be taken alone or used as a companion
product to support specific health situations.
Dr. Roseanne Nenninger, Nancy Kuhn, and I attended Vendor Day at
the University of Bridgeport College of Naturopathic Medicine.
IfHI Micro Conference was held in Nashville, TN. Hosted by
Larry Nesbit, the training and certification was a great success. Additional
kudos to Larry who trained his 1,000th student about the benefits
of eating right for your type.
Peter and the NY GenoType Group enjoyed an invigorating history
class/walk over the Brooklyn Bridge.
The Blood
Type Diet® iPhone app was launched! A great
tool to assist in meal planning and food shopping. The Droid
version will be released in early 2011.
Peter and Dr. Ginger Nash co-hosted an Eat Right 4 Your Type evening
in Hamden, CT with Thyme and Season health food store.
Dr. Ryan Partovi became the first resident in the collaboration
between the Center for Personalized Medicine and the University of
Bridgeport College of Naturopathic Medicine.
There are so many more special moments and not enough space to list them. Having looked back, I can now take a moment and look forward to our continuing growth as a concept and as an ever-expanding community. I am so grateful to all of you who share this journey into personalized medicine with us, and I wish you, your family and loved ones a happy and healthy holiday season and much good health, happiness and joy in the new year.
All my best,

Q & A: Depression, Stress, and Your Blood Type
Ginger Nash, ND, MIfHI
Dr. Ginger Nash is a naturopathic physician who works with Dr. D'Adamo at the Center for Personalized Medicine. We are fortunate to have her insight into the connection between blood type and stress and depression.
Q: Are individuals of certain blood types more susceptible to different
types of depression or anxiety? What causes this?
A: One's blood type can certainly predispose an individual to different ways
of responding to stress and balancing mood. This is because the gene that codes
for ABO blood type also affects other genes in close proximity that control things
like dopamine metabolism, cortisol levels, and other processes that will affect
the entire nervous system's coordination. For example, Type B needs additional
nitrogen rich foods and supplements because their bodies lack the ability to
produce a compound called nitric oxide to the extent that the other blood types
do. Nitric oxide helps coordinate the nervous system, immune system and cardiovascular
system. We know that when you are stressed all three of these systems are put
under more strain.
Another important factor is the stress hormone cortisol. Type O produces the least amount and Type A produces the most amount of cortisol. When cortisol is continually over-produced it can cause adrenal exhaustion and the corresponding symptoms of depression and fatigue. Type O’s reaction to stress can cause an overproduction of adrenaline which can make them more susceptible to anxiety when stressed. But again, long-term imbalances can create more depression from burn out of the nervous system as well.
Q: What role does everyday stress play in depression?
A: Certainly Type A, with their naturally higher levels of cortisol, are particularly
prone to problems from "everyday" stress. As the adrenal glands pump out more
and more cortisol they eventually tire out, causing the person to have a quicker
response to minor stressors. Type O’s are more prone to problems that arise from
an inability to clear stress hormones from their system quickly; it takes more
to get a Type O stressed but it takes more to de-stress them as well. That's
why they require more vigorous exercise, whereas Type A can do a lot with yoga
and Tai Chi for cortisol balance.
Q: What suggestions do you have for individuals of each blood type to alleviate
stress and/or depression?
A: So as I just mentioned, Type A does better with activities that clear cortisol
from their systems, like yoga and Tai Chi. Type O does better with more vigorous
exercise that clears a class of stress hormones called catecholamines from their
bodies. Type B can also benefit from more calming exercises especially if they
are prone to depression in the family. AB’s benefit from routine and anything
that keeps their immune system functioning properly like eating and going to
bed at the same time, routine cleansing, and avoiding extremes in terms of lifestyle.
Q: Are there any foods that may have mood enhancing benefits? What about supplements?
A: Foods that are rich in essential fatty acids have shown benefit in people
struggling with depression–fatty fish would be a good source of DHA and EPA.
Also, many nuts and seeds that are beneficials in your diet are rich in essential
fatty acids. Things like walnuts, pumpkin seeds, and almonds. Foods rich in Vitamin
B12 and folic acid, in addition to supplementation (Methyl
12 Plus™ is great),
are also beneficial. Brewer's yeast, brown rice, oats and animal proteins that
are good for your GenoType would be recommended. Some studies have shown a benefit
from regular dark chocolate consumption on mood. This is probably due to their
flavonoid content. Green tea is also rich in beneficial flavonoids that have
benefits for many reasons, but among them is mood as well. In addition, green
tea is rich in a naturally occurring amino acid, L-Theanine, which has calming
effects on the nervous system. So green tea is good for depression and anxiety,
which often go hand in hand.
Supplements I often recommend are B-complex, especially ones that contain pantethine
(B5), methylcobalamine (B12), pyridoxine (B6); and essential fatty acids.
Cortiguard® (especially
for Types A and B) and Catechol® (especially
for Types O and AB) are helpful in managing everyday stress. There are also some
wonderful herbs to manage mood, most famously St. John's Wort, Rhodiola, Bacopa
and Holy Basil according to one's GenoType. Sometimes I will use amino acids
that act as precursors to certain neurotransmitters but again, these are highly
specific recommendations based on a number of individual parameters. Things like
tyrosine, 5 hydroxytryptophan and the aforementioned L-theanine can be very helpful
for many people.
Seasonal Affective Disorder (SAD)
Ann Quasarano
Often called
the winter blues, SAD sufferers become
depressed when the winter season rolls around. Here are a
few suggestions for avoiding SAD this
winter.
Seasonal affective disorder (SAD) affects as many as half a million people
in the US each year. It’s thought that there are many more cases, including
those who have a milder form of SAD, who don’t seek treatment. Often
called the winter blues, SAD sufferers become depressed when
the winter season rolls around. Below are a few suggestions for avoiding SAD
this winter:
Spend some time outside every day.
Supplement with vitamin D3 (our Phyto
D 2000™ is
an excellent source).
Avoid simple carbohydrates, sugars, and alcohol.
Sit under a full spectrum light for at least 15 minutes daily.
Eat right for your type.
Exercise daily. Get at least 20 minutes per day (walking, yoga, or vigorous
exercise depending on type).
Socialize—get out of the house and spend time with friends and family.
Symptoms
Afternoon slumps with decreased energy and concentration
Carbohydrate cravings
Decreased interest in work or other activities
Depression that starts in fall or winter
Increased appetite with weight gain
Increased sleep and excessive daytime sleepiness
Lack of energy
Slow, sluggish, lethargic movement
Social withdrawal
When to see a doctor
A visit to your health care provider will look for other causes of the symptoms
and confirm the diagnosis. A psychological evaluation may be needed for more
severe depression.
Spotlight: K.T. Pederson, Norwegian Facebook
Group
Ann Quasarano
“I
strongly believe in this ‘diet.’ I really like to refer
to it as a lifestyle change, not diet. I know it works,
and I want to pass on the word. I'm a big advocate
of the BTD now, and already have gotten a few friends
and family to give it a try.”
This month we travel across the
globe to meet Kjell Thomas Pederson, a blood type dieter
from Norway who began the Norwegian Blood Type group on
Facebook!
Kjell, who is blood type A, began eating right for his type in February 2008,
when he was living in New York City. Prior to the recommendation from his Naturopathic
Physician, Kjell says he had never heard of the Blood Type Diet before.
“At the time, I was having a lot of health problems, but really got no help from
our allopathic medical system,” explained Kjell. “The diet was the first thing
I started doing, before taking any other supplements or remedies recommended
by the ND. Almost immediately I noticed HUGE improvements in my overall health.
In about two weeks time, I went from laying in bed with major fatigue to doing
two mile runs.”
He says that he had a lot of systemic symptoms and found that many of them were gone or alleviated after some time on the diet. “It has not solved all my concerns, but I believe it has been a huge help in my healing process. My issues turned out (most likely) to be autoimmune related.”
Although he still follows the Blood Type Diet®, Kjell admits that he is not
100% compliant. “One
of the things I love about this diet is not only what I should, or shouldn't
eat, but how I now have learned to listen to my body, and can almost immediately
tell if the food is right or wrong. Most my life I was mainly a meat, grain and
dairy eater, little did I know that I was supposed to load up on veggies instead.”
Kjell is a big supporter of eating right for your type and likes to help others
in their journey to health. “I
strongly believe in this ‘diet.’ I really like to refer
to it as a lifestyle change, not diet. I know it works,
and I want to pass on the word. I'm a big advocate
of the BTD now, and already have gotten a few friends
and family to give it a try.”
He started the group because he wanted to find like-minded people in his home country. “I did not find a group for it here in Norway, thus I wanted to start it. I think we have about 20 members right now, but I'm hoping more will join and be active in the group. Norway is a small country, but I know there are quite a few out there now aware of the BTD.”
He plans to travel to New York to meet the members of the New York City Blood
Type/GenoType group and would like to begin meetings in Norway to provide support
to people who are following the diet in Norway. “I would like to have group meetings in the future, if I can get the group properly sized and active.”
Blood Type/GenoType groups are sprouting up all over the world. Here is a link

Dietten / Spis rett for din Type and here are links to other groups internationally:

Right For Your Type News
Dr. D'Adamo's New Blog
Dr. D'Adamo has started a new blog geared towards science and recent developments
in genetic medicine, nutrition, and complexity theory. In keeping
with the movement towards individualized medicine, Dr. D'Adamo named
the blog (n=1).,
which in lay terms means "a sample size of one." In clinical trials,
the 'n number' is the number of participants or sample size in a study.
A study of 6,000 people would be depicted as '(n=6000)'. According
to Dr. D'Adamo, "(n=1). is my way of saying that we are are all part
of an ongoing study of ourselves." We encourage you to check out
the blog, as it changes frequently, and it contains fascinating information.
