Eat Right 4 Your (Blood) Type

I was reading this book and since I found it very interesting, I thought to share it with you.

According to this book only a type A should take little meat. The other group types, can. And type 0s do better if they eat it.
Now.. since I've been a vegan for almost 2 years (and I was getting close to raw) I read a lot of stuff about nutrition, but none of this raw veg (etc) movement talks about the importance of the blood types. Although I'll never eat meat for an etic issue, I'm just curious to know the truth.

Here is a little excerpt:

The story of humankind is the story of survival. More specifically, it is the story
of where humans lived and what they could eat there. It is about food--finding food and
moving to find food. We don't know for certain when human evolution began.
Neanderthals, the first humanoids we can recognize, may have developed 500,000 years
ago--or maybe even earlier. We do know human prehistory began in Africa, where we
evolved from human-like creatures. Early life was short, nasty and brutish. People died a
thousand different ways--opportunistic infections, parasites, animal attacks, broken
bones, childbirth--and they died young.
Neanderthals probably ate a rather crude diet of wild plants, grubs and the
scavenged leftovers from the kills of predatory animals. They were more prey than
predator, especially when it came to infections and parasitic afflictions. (Many of the
parasites, worms, flukes and infectious micro-organisms found in Africa do not stimulate
the immune system to produce a specific antibody to them, probably because the early
Type O people already had protection in the form of the antibodies they carried from
birth.)
As the human race moved around and was forced to adapt its diet to changing
conditions, the new diet provoked adaptations in the digestive tract and immune system
necessary for it to first survive and later thrive in each new habitat. These changes are
reflected in the development of the blood types, which appear to have arrived at critical
junctures of human development:
1. The ascent of humans to the top of the food chain (evolution of Type O to its
fullest expression).
2. The change from hunter-gatherer to a more domesticated agrarian lifestyle
(appearance of Type A).
3. The merging and migration of the races from the African homeland to Europe,
Asia and the Americas (development of Type B).
4. The modern intermingling of disparate groups (the arrival of Type AB).
Each blood type contains the genetic message of our ancestors' diets and
behaviours and although we're a long way away from early history, many of their traits
still affect us. Knowing these predispositions helps us to understand the logic of the blood
type diets.

Read it and tell me what do you think.
