On Tuesday, January 18th, barnesandnoble.com welcomed Dr Peter J. D'Adamo to discuss his latest book, EAT RIGHT 4 YOUR TYPE.
Cary
from bn.com: Good
evening, Dr D'Adamo, and welcome to bn.com. How are you? Where do we find you
tonight?
Peter
J. D' Adamo: I'm
fine, thank you. Trying to deal with the one-degree temperature in Connecticut,
which is interesting, because it hasn't been this cold in a while.

Lee
from New Canaan, CT: How
and when did you first discover the connection between blood type and food? Have
you met with much resistance from the medical community?
PD: The link originated with my
father, who actually had looked at blood type from the perspective of diet
almost 40 years ago. He had just simply noticed that, as long ago as then,
people didn't always do well on what would have been the type of spa diets that
were prescribed for various illnesses. I took his observations and built on them
by looking into science research and giving it that kind of a basis. As far the
idea being accepted by the medical community, I think it sounds absurd to most
medical professionals, since many of them are unaware that blood type is as
significant in the body as it is.

Maurice
from Boise, ID: What
exactly are glutens and lectins? What do they do?
PD: A lectin and a gluten are
proteins. Gluten is in one type of protein found in many plants. I think the
person is implying something about agglutination, which is different than
gluten. Agglutination is the process of cells kind of getting stuck together.
This is produced by many lectins, which are found in common foods. A recent
study showed that 36 out of 80 foods tested had some lectin in them. And what
makes it all so relevant to this discussion is that many of these lectins are
blood-type specific. So when you eat foods that contain a lectin that is
reactive with your blood type it can cause problems.

Gillian
from Sacramento, CA: How
does blood type relate to what we eat?
PD: Well, there's the lectins
in foods that we just discussed. But there's also metabolic influences that are
under the effect of one's blood type. For example, blood type O is known to have
elevated levels of stomach acid when compared to the other blood types. They
also have higher levels of enzymes in their intestines, which are there to break
down fat. One could ask why your blood type could influence a secretion from
your digestive track. In reality, it's not necessarily your blood type that
could influence how much acid you have in your stomach, but the gene for your
blood type linking with other genes and doing seemingly unrelated things.

Nadine
from New Haven, CT: What
about diabetics? How does this program affect us? Is there any research about
which blood types are more likely to be diabetic?
PD: There are several studies
which show that an increased number of people with type 1 or juvenile diabetes
have type A blood. There's probably some evidence to suggest that this is
related to two events which are not easy to explain in a paragraph! Suffice it
to say that there is an interaction between certain components of cow's milk and
cells of the pancreas which may be more pronounced in people who are type A.
It's also been noticed that type A children of type O mothers have higher rates
of diabetes, and this probably represents an immunological incompatibility,
since people who are type O (the mother) can carry antibodies against people who
are type A (the child). As far as diet is concerned, the appropriate diet for
each blood type is designed to optimize insulin efficiency and glucose
metabolism. Strangely enough, I've also noticed a very high percentage of my
patients of African descent who are type B have diabetes. One can only wonder if
the genetics of one's race may represent a good or bad fit with the genetics of
one's blood type, since the beneficial aspects of certain racial characteristics
designed for one geographical area of the world may be problematic in a blood
type for a blood type designed for a different.

David
from California: On
the updated food lists, Saw Palmetto is "unknown" for type As. Has
that changed?
PD: The updated food lists tend
to go a bit beyond the lists in my book EAT RIGHT 4 YOUR TYPE. If I've never
released any data on a particular fruit or herb, many times it is listed as
"unknown." The book that I am writing now is much more extensively
focused on supplements of this sort. In general, Saw Palmetto can be considered
"neutral" for type A, as it has no harmful aspects as per your blood
type, nor does it enhance any beneficial aspects of your blood type either.

Lilo
from Bradenton, FL: It's
a little difficult to cook right for a husband, type 0, and for myself, type AB.
Does your new book have menu suggestions addressing this dilemma?
PD: COOK
RIGHT 4 YOUR TYPE
is designed to provide recipes that allow for overlap between different blood
types, so when you see a particular recipe, at the top will be listed whether or
not it is usable by all blood types or any combination of blood types. Sometimes
advice is given with regard to meal planning also. Fortunately there is a
considerable amount of overlap with food from the neutral category, although it
is a dilemma that we face as well in the D'Adamo household.

Bobby
from Buffalo, NY: My
wife, a type B and a vegetarian of several years, cannot stomach the thought of
eating any formerly living creature, and as such, soy burgers, soy chicken
patties, et cetera, have long constituted a majority of her diet. In EAT RIGHT
you suggest that type Bs avoid substituting benign soy foods as main courses
instead of eating the highly beneficial meats. What can she possibly do?
PD: I think a choice has to be
made, and I, for one, can respect how a person can choose to consume or not
consume a food based on philosophical or moral considerations. I can only
provide somewhat objective data which I feel is not morally tinged in one
direction or another. This is a common problem in many type Os who are long-term
vegetarians. I am often confronted by vegetarian type Os who feel impelled to
tell me that they feel wonderful, to which I reply, "I am very happy for
you," since there are a lot of ways one can be healthy. The question of
whether one should change a philosophical or moral view to me is one of
necessity. Very sick people who are type O vegetarians are often quite amenable
to changing their diet and these are the people who do really need to do the
deep think. So my answer to your wife is to take from the system what she feels
comfortable with and if she needs more because of a health condition she can
deal with that later.

Lynne
Schuler from Virginia: When
will you be publishing the results of your ten-year trial of reproductive
cancers and ER4YT?
PD: Much of that is still in
nascent form. The results are encouraging; however, the longer I track cancer
cases the more convinced I am that as many people as possible need to be
followed for a period of time that is greater than ten years. It is difficult to
"tease out" the effects of ER4YT and other interventions. So we are
left only to compare very simple survival rates and to ask if ER4YT has the
effect of influencing these. In terms of breast cancer, a very crude estimate of
the data shows that following the recommendations of ER4YT and prudent
conventional treatment produces an increase in survival percentages of 15 to 35
percent, depending on the grade of cancer and its stage. The major difficulty is
that this type of analysis should be done by independent researchers, since my
doing it will be viewed askance by critics whose response will only be, "Of
course he got those results, he's the one who came up with the theory!

Cindy
from Vancouver, BC: Hi
Dr D'Adamo. I have been on this way of eating for just over a year now. I feel way
better! Thank you so much. I am O+ and was a "starchaholic," eating no
meat (only seafood) for about four years prior to reading your book. I have
"unexplained fertility" and wonder what ideas you may have for
supplementation to assist in getting pregnant. And yes, we are having sex,
teehee! Thank you in advance, Cindy
PD: Although this is not an
advice column (!), there is some great evidence suggesting that vitamin C and
green tea should be taken by people desirous at greater success of conception.
It is important that the vitamin C be food derived, rather than synthetic
vitamin C. Studies show that in doses as little as 250 milligrams per day, green
tea contains polyphenols, a type of antioxidant which apparently assists the
early cells in dividing efficiently. I would definitely recommend very good
adherence to the blood-type diet, which you seem to be doing. The reason for
this is that many foods which are "avoids" for a blood type can "inoculate"
a woman to react to the husband's sperm if he has a blood type different than
hers. This is called "cervical hostility" and the avoidance of
cervical hostility is probably the major reason that conception and the
avoidance of miscarriage is a common enough effect of the blood-type diet.

Dianne
from California: Do
you have plans to do any personal appearances in the U.S. this year following
the release of your third book, LIVE RIGHT 4 YOUR TYPE?
PD: Oh, I suppose they will
stick me on an airplane at some point! The web site -- www.dadamo.com -- has a
calendar, which I will update typically when I'm on the road. As far as LIVE
RIGHT is concerned it is almost done at this point. It has taken the better part
of two years to write and has some studies of blood type and personality which
featured sample sizes of more than 20,000 people. Much of the new stuff I've
learned in the last four years will be interesting to people who have mastered
ER4YT. The nice thing is that LIVE RIGHT will take off where EAT RIGHT left off.

Larry
from Ramapo, NJ: Do
calories matter on this diet?
PD: The answer is that they do
and they don't. For example, a food containing a lectin capable of interacting
metabolically with the body is important in that respect more than it is with
respect to its calorie content. This is important because if we simply looked at
dieting as calorie restriction, we would lose the one major benefit gained by
dieting according to one's blood type, and that is the maintenance of something
called "active tissue mass." When people diet solely on body
restrictions, they lose body fat but they also lose body tissue mass, which is
the part of the body that burns calories, which is muscles, brain, et cetera.
Losing weight by losing body fat is great, but losing weight by losing active
tissue mass is terrible because your metabolic rate will be lower after the diet
than it was before. If you follow the diet for your blood type, you weight loss
will be consistent, though slower, than a drastic calorie restriction diet, but
you will maintain or increase your active tissue mass.

John
from Flint, MI: Is
there any blood type predisposed to be lactose intolerant?
PD: No, there's not. And one
can also find lactose intolerance in blood types such as B, for which dairy
products are recommended. Thus if a food is recommended by virtue of blood type,
one should be cognizant that there may be other considerations as well.
___________________
Pearson
from Rochester, NY: I
read something in your book about exercising right for your blood type. What
does that mean?
PD: Exercise takes on some
additional significance if viewed from the perspective of blood type. The
reason for that is that blood types have been shown to have different chemical
reactions to stress. This is probably also more of a genetic link than a
physiological link. For example, when exposed to stress (the researchers used a
tape loop of a baby crying), blood types A and B respond to very high levels of
a hormone called cortazol. Cortazol has in general bad effects almost everywhere
in the body, but some of its major effects are on your metabolism and
cardiovascular system. Exercises like yoga have been shown to lower cortazol.
Type O tends to respond to stress with higher levels of catecholamines, such as
adrenaline, when they are stressed. Catecholamines are best lowered with aerobic
cardiovascular exercise, so with blood type we can go a step further than simply
saying "exercise is good for you"; we can use a specifically tailored
strategy to lower chemical mediators of stress particular to that blood type.

Rhonda
O- (INFP) from Circleville, OH: I
am concerned about my son's eating habits; he is a O like myself and likes pasta
food. How do you suggest integrating Italian food into an O's diet while still
sticking to the ER4YT diet?
PD: I
think the important thing is to explain to your son that pasta that he's eating
in 2000 is very different than his ancestors might have eaten in the old
country. Thirty years ago, wheat was about 2 percent protein, but now through
hybridization and genetic engineering we have increased the protein content of
several strains of wheat to almost 14 percent, in the misguided notion that all
those people in the Third World will benefit from that in their diet. The
problem is that all the bad things in wheat are in the protein portion, such as
the lectins, glutens, and gliadins. Reactions to wheat are now so common that 80
percent of the population carries antibodies to gliadin. Many have no symptoms,
but in years past this would have been considered diagnostic of celiac disease.
The link between the overconsumption of these lectin-containing grains and
obesity should be apparent to anyone, since about 40 percent of an average
person's calories come from some form of wheat product. Most people don't
realize this because many people think a bagel is made of the same thing as a
bowl of spaghetti.
