I think you missed the analogy. I was comparing quality of protein to build quality of a car. Either way, you are way oversimplifying the process by which protein powder is made. And that's fine, you entitled to believe what you want. If I can dig up the podcast about protein powder in the archive of the show I listen to I'll post it, but suffice it to say, you don't just dehydrate dairy and put it in a tub. And if there is a $15 tub of protein and a $60 tube of protein, they sure as hell didn't use the same process to get the end product regardless of what "extras" or "additives" they claim to use.
Regardless, I agree real food is a better choice, protein powder is a last resort.
