Whats Your Type?
Examining The Blood Type Diet

• By Corrine Ryser, Jason Gue, Thomas Morgan,

What is the blood type diet based on?

• Peter D'Adamo, ND, the author behind the Eat
  Right for Your Blood Type is a graduate of
  Bastyr University, now in private practice, in
  Connecticut and has been doing about 15 years of
  his own research based on 35 years of research by
  his father, James D'Adamo, who is also a
  naturopathic physician, and whose pioneering work
  with blood types and diet was described in the
  book One Man's Food.The authors theory is
  based on research within, amongst others,
  physical anthropology, neurology, biochemistry,
  nutrition, lectinology, epidemiology, psychology,
  immunology and genetics. The premise of the book
  itself is that if you use your blood type as a
  guide for eating and living, you will be
  healthier, you will subsequently reach your ideal
  body weight as well as slow down the aging
  process. Because blood types historically evolved
  as a result of changes in our diet, culture, and
  social conditions, each blood type has particular
  strengths and limitations. He presumes that when
  these are known and followed, it becomes easier
  to maintain good health.

• Dr. DAdamo concludes that blood type is a
  powerful indicator of your genetic code. He
  believes that blood types have evolved over
  thousands of years and contain the genetic
  message of diets and behaviors from our
  ancestors. By following the diet prescribed for
  one's specific, blood type, an individual can
  make choices that correspond to their biological
  profile.While several systems exist to
  categorize blood, including Lewis, Rhesus (Rh),
  and MN blood group systems, Dr. D'Adamo has found
  that 90 of the factors dealing with the
  connection between health and blood type are
  dependent on the ABO, or primary blood type
  system.

• Every life form has unique antigens that form
  part of its chemical signature. Similarly, each
  blood type possesses an antigen with a unique
  chemical structure. Blood type antigens are
  ubiquitous throughout the body and are among the
  most powerful antigens involved in the process of
  identification of "friend or foe or self vs.
  non-self."
• When the body senses foreign antigens, antibodies
  are generated which defend the body against the
  invaders. The "anti-other-blood" type antibodies
  are among the strongest antibodies in our immune
  system.
• It has long been recognized that some foods are
  capable of causing the cells of a certain blood
  type to agglutinate while having no impact on
  cells of another blood type. This reaction is
  dependent upon the interaction of human cells
  with the lectins found in food.

5

• A lectin can be defined as any compound found in
  nature, usually diverse protein structures, which
  can interact with surface antigens found on the
  body's cells, causing them to agglutinate.
  Following ingestion of food, a chemical reaction
  can occur between the food you eat and your blood
  or tissues because of these lectins. Many food
  lectins have characteristics sufficiently similar
  to certain blood type antigens to be identified
  as an enemy. If you eat a food that contains
  lectins incompatible with your blood type, the
  blood cells will agglutinate. Food lectins can
  also interact with white blood cells, acting as
  mitogens and stimulating cell division and
  replication.
• Essentially, when you eat a food containing
  protein lectins that are incompatible with your
  blood type antigen, the lectins target an organ
  or bodily system and begin to agglutinate blood
  cells in that area leading to health problems,
  weight gain, etc.

6

• The interaction of specific food lectins with
  blood type can play a large role in the
  determination of which foods act as medicine or
  poison for an individual. This interaction, along
  with other genetic predispositions associated
  with blood types, forms the foundation of the
  dietary recommendations proposed in this book.
• Dr. D'Adamo discusses characteristics of each
  blood type and makes recommendations for diet,
  supplementation, botanical support, and exercise.
  In the chapters dedicated to specific blood
  types, he recommends foods which are beneficial,
  neutral, or should be avoided. The diet also
  zones in on medical problems and their
  correlation to blood type as well as strategies
  for their prevention or treatment.

The Review, in the Words of Dr. DAlamo

• The essence of the blood type connection rests in
  these facts
• Your blood type - O, A, B, AB - is a powerful
  genetic fingerprint that identifies you as surely
  as your DNA.
• When you use the individualized characteristics
  of your blood type as a guidepost for eating and
  living, you will be healthier, you will naturally
  reach your ideal weight, and you will slow the
  process of aging.
• Your blood type is a genetic blueprint for who
  you are, a guide to how you can live most
  healthfully.
• The key to the significance of blood type can be
  found in the story of human evolution Type O is
  the oldest Type A evolved with agrarian society
  Type B emerged as humans migrated north into
  colder, harsher territories and Type AB was a
  thoroughly modern adaptation, a result of the
  intermingling of disparate groups. This
  development relates directly to the dietary needs
  of each blood type today.

33
All theory, no proof!

• No data or study done specifically for these
  ideas!
• Core idea of diet Eliminating Lectins.
• No pathologist I know has ever mentioned tissue
  infarction from lectin-induced red cell
  agglutination as a cause of any disease in
  humans. (Klaper, M.D.)

34
Questionable Statements

• "Type O's do not tolerate whole wheat products at
  all, (DAdamo, 63)
• No pictures, biopsies, or supporting material.
• Claims hypothyroidism is caused by Type O people
  do not produce enough iodine.
• People do not produce iodine!
• Tries to apply theories to consumption of milk.
• Intolerance to milk not suffered exclusively to
  any blood- type.

35
Holes in theory

• Affects of disease and conditions not exclusive
  to blood-type.
• Affects of aging.
• Genetic variations is somewhat weak argument.
• Ex. Eye color, hair color ? Does not affect
  health.
• Generally bad idea to restrict diet.
• Consult your physician!

36
Expert Opposition

• One of the book's most disturbing
  characteristics is the frightening images that
  the author calls forth without providing
  scientific documentation. (Klaper, M.D.)
• it's debatable that diet prescriptions based on
  blood type are the answer. In fact, there's no
  science to support the strategy. (Callahan, MS,
  RD)
• "I think we all have individual needs, but basing
  what you eat on blood type is ridiculous,
  (Kirby)
• "there's no indication that blood type has
  anything to do with anything other than blood
  type. Your basic nutrition needs are the same
  whether you're type A positive or B negative,
  (Hogan)

37
Salvaging Ideas

• No one diet is appropriate for any one person.
• Varying metabolisms, health conditions, tastes,
  finances.
• Non-processed foods are generally better than
  processed.
• Recommendations steer audience clear of processed
  foods.
• Any change in your regular diet may be
  beneficial, as any health diet will attempt to
  remove those foods obviously bad for you.
