Beef vs. Chicken vs. Fish

[theBruiser500]

A Diet For a New America says chicken and beef and pork are pretty much all the same for you in terms of health (bad). Mad Cowboy I just read says fish is bad too and the same saying "they are all flesh from animals" and says it's fat content is 60% while chiken and beef are 70% or something like that, so basically it's comparable in how bad it is. Any of you guys have mor einfo on this?
