Maybe one day the FDA will come up with an actual protein rating system instead of the current PDCAAS joke and we won't have to rely on so many different sources.

Two of my friends, well I have four friends but two of them are nutritionist one a vegan to the point of obsession, which I guess is reduntant and one who has trained pro bodybuilders and I rely on them for my diet info. Both agree that things that don't have muscles are not very efficient at feeding muscles without very careful planning and knowledge of what each food contains, and that there is no more effecient protein than an egg white.

They disagree on everything else.
