Two more videos which show not only that the scientific evidence indicates that a low salt diet does not greatly reduce hypertension, but that it also vastly increases the bodies production of triglycerides, angiotensin, aldosterone, cholesterol, and raises insulin resistance all of which are harmful to cardiac health.

Clue to salt-sensitive blood pressure found

About half of all people with high blood pressure exhibit SSBP. Their blood pressure goes up or down acutely, mirroring high or low consumption and resulting blood levels of dietary salt (primarily sodium chloride). But salt sensitivity also occurs in about 25% of people who do not have hypertension.

Despite the well-established link between high salt intake and cardiovascular disease and stroke, “the mechanism of SSBP is poorly understood, and it remains an untreatable cardiovascular risk with no widely available diagnostic tool,” the VUMC researchers reported recently in the journal Circulation Research.

various places talk about how to 'test' yourself to see if you are salt sensitive or not. There isn't an official test for it.
There is also the argument that the problem is not too much sodium but insufficient potassium intake.

It is proving so difficult to find trustworthy definitive answers on this.
