Will FDA set maximum limit for salt content?

Today the Institute of Medicine announced that the food industry has not done enough to cut back on the sodium content of their (mostly processed) food products and asked FDA to set maximum limits on the sodium level of various foods. So far FDA has not decided to regulate sodium levels. We hope that some level of limitation gets set by FDA at least on processed foods (such as soups).

Please note that the maximum amount of sodium a healthy person should take is 2,300 milligrams. The American average is 3,400 milligrams. In U.S, one out of three adults has high blood pressure, for which salt is a significant contributor. So FDA, what is the hold for?!
