Statistics show that the majority of people has a high blood pressure. In that sense, reducing your salt intake is a good general advice.
In addition, salt stresses the kidneys, and some other organs too. So even if your blood pressure is normal, it’s a good idea to limit your salt intake.
Keep in mind that humans evolved in an environment where salt was quite scarce. So did our ancestors, so our bodies have adapted to very little salt intake. The amount of salt we tend to consume nowadays is absolutely unnatural.
