There are certain things one has to cook with salt—or else it will taste like cardboard or toilet tissue —eg. pasta!
Pasta and rice are just the most obvious ones. Everything tastes awful without salt. You can add it yourself to something like steak but not to anything that requires cooking as opposed to something like grilling. The medical profession should get on this, as well as the restaurateurs, and state the facts.
I am Italian. I have never salted the pasta water. There is enough salt in the cheese and sauce.
However, I couldnt imagine chinese food without salt.
