Well if you read my posts you might come to see that meat is also very dangerous for the health :)
It is not a part of the food chain for herbivores, and only sometimes for omnivores like humans.
Proteins must be broken down and rebuild to human proteins, that is not a efficient way or good protein source for that matter, eat fibers and let your E.coli produce the amino acids you need and eat vegetarian proteins, they are easier to digest :)
If you where to build a house, you by planks, not ready made houses, brake them down and reconstruct into a new house!

Peace
