Blood Type Diet
“I believed that no two people on the face of the earth
were alike; no two people have the same fingerprints, lip prints,
or voice prints. No two blades of grass or snowflakes are alike.
Because I felt that all people were different from one another,
I did not think it was logical that they should eat the same foods.
It became clear to me that since each person was housed in a special
body with different strengths, weaknesses, and nutritional requirements,
the only way to maintain health or cure illness was to accommodate
to that particular patient’s specific needs.” James D’Adamo (1)
I completely agree with this
statement, alternatively said: “one man’s food is another man’s
poison.”
“Your
blood type is the key that unlocks the door to the mysteries of
health, disease, longevity, physical vitality, and emotional strength.”
Peter D’Adamo (1)
I disagree with this statement. In my experience of using
blood type to determine an individual’s personalised eating plan
I have found it to be useful on a number of occasions, particularly
with recommendations on what foods to avoid. However I believe
that anyone who says that there is one single KEY that unlocks
the door to health is very misled.
The key to health and vitality lies in a synergy which
I have written about many times and combining it with an individualised
approach. To recap the elements include the following:
·
Supportive nutrition which basically
means eating a diet composed mainly of whole foods, emphasising
quality proteins, fibrous carbohydrates, complex carbohydrates,
and good fats and oils and through awareness of your body’s reaction
tailoring the amount of each to your own body – finding your metabolic
type
·
Need for muscle
·
Cardio in moderation
·
Plenty of water
·
Adequate sleep
·
Additionally and importantly the
right mindset
So in the following article I will review the Blood Typing
Diet.
Firstly to find out your blood type if you are not sure
you could:
- Consult your doctor
- Give blood
- Do a simple thumb prick test available at some chemists and health
food stores or try the internet to pick up a test.
Science behind Blood typing
A single speck of blood contains the entire genetic code
for a human being. This code was the product passed on through
generations from our ancestors. The four blood types O, A, B and
AB are named so because of their differing qualities in relation
to the immune system. Antigens are the chemical markers that determine
your blood type. They form part of our chemical fingerprint by
possessing a different antigen. Antigens are the body’s internal
security system – so when your immune system finds a foreign intruder
(e.g. a foreign antigen from bacteria) it checks with your blood
type antigen to see if it is friend or foe.
Now in regards to the role that blood typing plays in
diet: as I previously said it is more useful in knowing which
foods to avoid rather than eat. This is due to the presence of
dietary lectins, which consist of protein and are found in around
30 percent of food. They can be inhibited through cooking and
digestion to some degree however if they reach the blood stream
they can appear like foreign antigens interfering with digestion
and absorption. They can also result in nutrient deficiencies,
food allergies, infertility, arthritis, diarrhoea, irritability,
IBS, intestinal gas. (MT)
Positive aspects to the Blood type diet
The basis is biochemical individuality which has been
extensively documented (I encourage you to read “Biochemical Individuality”
by Roger J. Williams for a more comprehensive and scientific understanding).
The science behind lectins is fascinating and has some truth in
my opinion but it is still far from being an exact science.
Additionally, most of the diets (except AB) recommend
reducing the amount of wheat. In my experience wheat is a problem
to some degree for almost everyone. It has been overused especially
in the form of processed carbohydrates like bread, pasta, and
breakfast cereal abusing our digestive system. Leaving wheat out
of the diet has in every case resulted in health improvements
in my experience.
The recommendations consist of whole foods which is an
improvement for people currently consuming a SAD (Standard American
Diet), but which should be renamed to SWD (Standard World Diet)
– as most of the world has come under the influence of excessive
sugar, trans fatty acids (from fast food) and toxic food which
are far from how nature intended them to be consumed.
Negative aspects to Blood type diet recommendation
However I disagree with many aspects regarding the blood
typing diet including recommended foods, the fact that the diet
remains set in stone and allows no shifts, and the advice for
specific exercise regimes for specific blood types. These are
outlined below:
1. Foods recommended I believe are not healthy
- Soy for one is heavily promoted especially for A types. I believe
soy is not a health promoting food especially for males as it
has been shown to affect sperm strength and number. Soy has
also been linked to thyroid problems.
- Vegetable oils are another concern and have been linked to heart disease
and many other conditions.
2. Set in stone
Blood types don’t change however certain medical conditions,
environmental influences and stress result in a need to adjust
the diet accordingly. For example colder climates/winter and stress
result in an increased protein need for many. Many women who have
a strong awareness on the body will experience differing needs
for proteins/carbohydrates/fats throughout the month. On a bigger
note pregnancy will also have a powerful shift on diet. Medical
conditions like Candida and high blood sugar problems will recommend
the absence of starchy carbohydrates from the diet (grains, below
ground vegetables), which may be good for O types but they are
not the only ones who suffer from these conditions.
3. Exercise
Regarding exercise I agree some people are more suited
to some exercises than others. But I believe a balance is important
e.g. in terms of Chinese medicine having a Ying and Yang approach
– not just doing intense exercise or light exercise and combining
strength, cardiovascular and flexibility into your training.
But I would like to give you an overview according to
the Author of “Eat right for your type” Peter J. D’Adamo. As I
said previously I often outline with clients some foods they should
avoid according to the blood type diet, which has often been very
useful. Additionally, in my experience the recommendations for
O blood types have proven the most beneficial. When I come across
O type clients and they eat in this manner then in every case
to date they have reported fat-loss, increased energy, vitality
and wellbeing. I have also experienced this diet in relation to
eating a grain based diet (which I believe is not the answer for
anyone) and a vegetarian diet for a short period, and I have no
doubt I am a caveman. Obviously this diet has been a hit with
many but the high protein diet is in my opinion and experience
not the answer to everyone as Atkins and high protein diet proponents
say.

Eating according to your blood type has been a lifework
for the D’Adamo family spanning over 40 years of research. I am
never quick to dismiss anyone who dedicates their life so intensely
to such a topic, but I believe sometimes we do not allow new thoughts
to enter and hold onto old paradigms that have lost their relevance
in the name of preservation. I have found it interesting personally
to know my clients blood type and then see when the eat optimally
the foods they eat and the ones they leave out, but the overall
correlations (over all blood types) have not convinced me to base
my nutritional recommendations on blood type. I still believe
the science of Metabolic Typing to be a far more accurate model
(though also not perfect), whereby I have found more consistent
results.
