Blood Types O and B also have greater susceptibility to infectious diseases such as scarlet fever, cholera, |
typhoid, or the bubonic plague, while Type A shows greater susceptibility to the smallpox virus, and it is more |
prone to blood clotting. Blood-sucking insects (that carry diseases) prefer Type O blood. |
|
How does that help doctors and their patients? |
|
Unfortunately, it doesn't. For instance, gastritis modestly prevails in blood groups A and O, so with more than |
80% of the world population being part of the A or O group, not only would it be impractical or pointless to |
suggest dietary changes for preventive or therapeutic purposes, but what should the recommendations be? |
Since there is such a big variety of possible causes for gastritis, there are no universal therapeutic or dietary |
solutions that are practical and can be safely applied to such a large percentage of the population. The same |
circumstances apply when trying to formulate diets around blood types for any other medical disorders, as |
not one single disease is exclusive to one particular blood type. |
|
Ever since first becoming aware of the "eat-right-for-your-type" proposition, I was as curious and intrigued as |
many other researchers and practitioners to clinically apply those theories by comparing patients' blood types |
to their medical disorders - looking for trends or a pattern. |
|
It quickly became apparent that high blood sugar, high blood pressure, or high stomach acid types shared |
the same blood groups with those exhibiting low blood sugar, low blood pressure, or low stomach acid. As |
expected, the same applied to people with a lifelong tendency for weight gain, weight loss, nearsightedness, |
farsightedness..., as well as other "hyper" versus "hypo" conditions, so at this time, blood types don't serve as |
a helpful screening method. |
|
How do different Blood Types compare to a patient's chemical / nutritional profile? |
|
Since the "eat-right-4-your-type" concept mainly focuses on dietary lifestyles being matched to blood groups, |
it would stand to reason that blood types should match the chemical and nutritional profiles of an individual - |
sort of like the Metabolic Typing of patients - where diets are adjusted according to someone's biochemical |
or genetic make-up. |
|
Unfortunately, there is no practical or clinical match whatsoever - just like eye color and hair color are not |
a practical or clinical indication of a person's present or future medical risks (other than those with blue eyes |
or red hair being more prone for sun damage). Years ago, plotting an individual's Biorhythm was another popular concept that had its followers track someone's physical, intellectual and emotional well-being ( trying |
to identify critical days), although this method equally lacked scientific support. |

Some people claim that since following the "eat-right-4-your-type'' recommendations, they had lost weight, |
or felt otherwise better, however when asked about any specific changes made, they invariably consisted |
of lifestyle changes that are universally considered to be beneficial - regardless of someone's blood type - |
such as cutting out junk food, and/or eliminating foods which either cause, or have an unfavorable impact on |
specific medical problems one is suffering from. |
|
Increasing healthier foods, or avoiding food sources that someone has an intolerance or allergy to (dairy, |
wheat, eggs, nuts, shellfish, etc...), will definitely have a positive impact on someone's health, but the need to |
do so has mostly a genetic basis that happens with all blood types, not just certain blood groups as claimed |
by "eat-right-4-your-blood type" proponents - so subsequently this does not support, but rather discredit the |
"Blood Type Diet" concept. |
|
The notion that individuals with certain blood types suffer from specific medical problems ("Blood Type O |
is commonly affected with hypothyroidism, high stomach acid [leading to ulcers], and thinner blood...") is |
clinically incorrect. Many medical conditions develop from non-dietary causes and change over a lifetime, |
but would have to remain fixed according to the premises of the "Blood Type Diet." |
