Protein by weight & Utilization
Food Protein by weight %Net protein Utilization
Eggs 12 94
Milk 4 82
Fish 18- 25 80
cheese 22-36 80
brown rice 8 70
meat and fowl 19-31 68
soy bean flour 42 61
(whey, milk derivative which is a refined product, has even more net protein than eggs)
The chart tells us that an egg contain only 12 percent protein by weight. Yet because of the specific balance of amino acids present in that protein, 94 percent of it can be used by your body!
42% of soy-bean flour is protein, but the make up of that protein is such that your body is able to use only 61 percent of it.
SO there is a big difference between how much protein a food contains and how much of that protein you can actually use to build muscle.
Eggs an arbitrary value of a perfect 100!
