it's actually a complex topic.
have you ever considered this? :

"Protein
With the way animals are raised today, it
is important to have a healthy consistent
source of protein. Wheatgrass contains
20 percent protein, (Meat has %17 and
eggs have %12). Protein in grass is in the
form of poly peptides, shorter and simpler
chains of amino acids which are
deposited more efficiently into the
bloodstream and blood tissues. Protein is
essential to build and repair tissues, and
is an important building block of bones,
muscles, cartlidge, skin, and blood."

I'm romanian and we have in my region a traditional "soup" called "bors". It's contents are as for a normal soup but the extra ingredient it's the "bors" - fermented mixture of wheat bran and corn flower. It adds a sour taste to the soup (I love it) and extra vitamins.
The "bors" juice you can have it on it's own, apparently it's very good for your stomach as it has lots of useful batceria. Yes, there's useful bacteria too , the ones that help with digestion.
Maybe I'm a bit outside the topic here but I just thought I should point out the existence of this stuff.
