Usable Protein Contained in Eggs Versus Rice and Beans

Very good points made here!

Life-Systems Engineering Science by Professor Brian Peskin

An egg white is an ideal protein with a rating of 100% digestibility. On the other hand, the protein in brown rice is ONLY 59% usable and that in beans is ONLY 49% usable because of their fiber and other anti-nutritional factors such as those mentioned in [a 2005 report by the Association of Official Analytical Chemists International (AOAC)]. Therefore, the usability of the protein in rice and beans is approximately half that of an egg!

Now, couple this with the fact that the rice and beans contain only about half the quantity of protein that is in a comparable quantity of eggs. So rice and beans have half the protein of eggs, and THAT protein is only half as usable as that in eggs. This means that the rice and beans have AT MOST a mere one-fourth the usable protein amount of eggs. No problem, you say – I’ll…
