lose a lot of good stuff with them yolks too unfortunately

from what ive heard casein isnt worth it, whey is the best bang for your buck, supplemented with egg protein its even better

beans are also the ****, they have a good amount of protein generally and a lot less cholesterol than eggs

fwiw: ive never been "diagnosed" but im quite sure im a sufferer of S.A.D. and im already feeling some of it this year after just a week of crappy weather.
so today i bought a box of italian butter cookies and then i ate them all.

also protein powder/supplements in general are absorbed much more efficiently into your system with real food also
