I believe that most of your protein intake should come from whole-foods because not only do u get the protein u need, but you also get minerals and vitamins. Also, one might argue that protein powders feature exclusively whey protein will provide you only with relatively fast-absorption protein, while a can of tune, cottage cheese or steak will provide you with a more long-lasting proteic supply.
However, it is importante to remember that powders etc are SUPPLEMENTS, intended to SUPPLEMENT your diet and not take over whole foods. Stick to 2 MRP or Whey Shakes a day imo and educate yourself to get the protein you need from whole-food sources.
