History of the Blood Type Diet
How did there come to be diets by blood type? The history of the blood type
diet could be the most convincing aspect of a diet that has its share of critics.
It goes back all the way to the dawn of humankind. The theory is that in the
beginning all people had what we call O type blood. This blood type was conducive
for the digestion of meats, fruits, vegetables, berries, nuts and legumes, basically
all the stuff that cavemen could scrounge together to avoid starvation. Therefore
people who have O type blood today, have the blood type of their ancestors and
should theoretically have a caveman’s diet. This also includes hearty exercise.
While this may not be as rigorous as running away from an adult Hyenadon, it
does mean running and swimming. About 25,000 to 15,000 years ago our ancestors
got their act together and started harvesting grains. This was a radical change
in diet and resulted in the A type blood group diet. Therefore, those with A
type blood should eat more grains and less meat and dairy. 10,000 years after
this, people from Africa began moving elsewhere in the world. This mixing led
to the advent of B type blood. Literally a combination of A and O, anyone with
B type blood can eat a combination of A and O’s diet. They can also digest dairy
products, which is much harder for A’s and O’s. Last but not least is AB blood.
A relative newcomer in the realm of blood types AB has only been around for
about 1000 years. Believed to be derived from the Mongol invasion that brought
large amounts of B type Asians in contact with A type Europeans. AB’s can generally
eat a mixture of all three other diets.
