Exactly. That means that I can receive any blood type.
Damn it has been so many years since I had to study this stuff or even think about the subject. I never got many answers then or now as to why there is a split in blood types in humans in the first place.
If we did indeed all start out in Africa and spread upon the earth, what could have caused the change in blood types ????
First time I became pregnant was the first time I remember being tested for blood type-----My doctor was happy as I was a +, so I would not reject the blood from a father to the baby with a rejecting responce.
For years the Courts used blood types before DNA to rule out the possible or not likely parentage of a child.
Finally science developed a drug for woman to take that would stop any conflict in their body trying to reject blood that was different from theirs in + or - and effecting the mother and child. I do remember reading that in most cases the first child born would have few problems, when the second child came about the mother had built up a shall we say allergy to the fathers blood type and if the child was born there could be big problems for the child.
Once DNA came on the scene a way to scientifically link parents to a child and even go back to one ago generation to another, the blood typing thing became as remote as using leaches to draw blood.
As far as I can see here this diet is a dream of a snake oil salesman. People eat what they have at hand to survive. Blood type
has nothing to do with nutrition, it is the food that is available to us that can cause problems-----Lactose intolerance, and allergies
to some foods. Why the allergy ???? So many questions and so few answers today, perhaps tomorrow we may find reasons but I do not think blood type diets are the answers.
