I get that you need protein to build muscle, but I don't understand why eggs/milk/meat/fish/yogurt/legumes/etc is not enough. The cavemen did ok without protein shakes. They are also super expensive. And I have been taught that eating too much protein is very hard on your kidneys, and that excessive protein just passes through you, accomplishing nothing but stressing your kidneys and spending money.
Some people cycle it in and out of their diets. You are right- too much of that stuff is not good. To build adequate muscle for your frame, having a high protein diet from the sources you mentioned above is enough. To get bigger you'll need to take in more of it.
