What exactly are you supposed to eat if you want to build muscles effectively?

[*Laurelindo*]

Does anyone know what you should eat while working out in order to build muscles as effectively as possible?
I'm wondering because I seem to have bad luck with this, no matter what I eat there's almost always someone who claims it's "not good" or contains "worthless proteins" etc, and it's starting to become frustrating.

I used to drink a mix of milk, eggs and bananas after working out - I was 100% sure that this would be an awesome recovery drink, for obvious reasons - but it turned out not even that is ideal since raw eggs apparently contain bad proteins as well; and then I heard the same thing about black pudding (while eating black pudding before a workout ).

I'm fairly new at this, by the way - I worked out a few times some weeks ago but now I'm starting over again.
