I just can't give up salt.
Salt is kind of questionablew as far as how important it is for blood pressure. See, acutely, when you intake salt and it gets into your blood, your body adds water to the blood to dilute the salt content back to where it was, so you have a slight increase in blood pressure temporarily. Then, your kidneys notice that your blood volume is higher than it should be (I don't remember how they know, maybe because the protein level drops a little), so they remove the excess salt and liquid, and your blood pressure drops back down.
So, in about 3/4 of people, there is not really a significant effect of salt on you blood pressure. truly.
In the other 1/4, they are sensitive to salt, and their blood pressure is elevated by salt, and resets to a higher level. slightly higher, but significant.
The powers-that-be decreed that the reduced risk for that 1/4 of the population was enough that it was worth telling everyone to reduce their salt intake, even though for 75% of us there is no effect at all.
Unfortunately, without careful blood pressure measurements and careful monitoring of your response to salt intake, there is no way to know whether you are in that 3/4 or in that 1/4.
