net protein utilization
taken from Arnold's The New Encyclopedia of Modern BodyBuilding:
food / %protein by weight / %net utilization
eggs / 14 / 94
milk / 12 / 82
fish / 18-25 / 80
cheese / 22-36 / 70
brown rice / 8 / 70
meat and fowl /19-31 / 68
soybean flour / 42 / 61
so it basically says that although eggs are only 14% protein by weight, your body is actually able to use 94% of that protein to build muscle, where as chicken is btw 19-31%, your body can only use 70% of that protein to build muscle... thats why protein from eggs is essential because it is the most effective... so hard boil em, scramble, make an omlette, poach em, eat em raw, put em on a sandwiche, but a good diet contains some egg protein...
