Rigorous studies showed that when salt consumption is reduced, blood pressure is just as likely to rise (~15%) as it is to decline (~18%). The other 70% of subjects had no change in their blood pressure when salt was reduced in their diets (1). Moreover, most recent research shows that significant reduction in dietary salt increased death events from cardiovascular disease, the very thing these regulations hoped to prevent.
Current guidelines recommend limiting sodium intake to 2,300 milligrams a day for healthy people—with the FDA intent on lowering it further. However, during the study it was found that healthy adults consuming less than 2,500 milligrams of sodium a day had higher blood pressure than participants who consumed higher amounts of sodium.
