Why do people say that sodium causes high blood pressure? Salt is sodium chloride not sodium.?

A basic school knowledge of osmosis wouldn't have let you ask this question. Sorry if I hurt. Response to your additional details:- kindly specify what you want to prove, and privately did you asked a question or do you want to teach us some of your theories?

Your school teacher would have solved your queries better than us, also thank you for the recreation .

Yes, the concept of HBP being related to dietary salts is incredibly simplistic - it's as though some doctors learned about osmosis and ran with it. It doesn't give the body credit for being able to manage its sodium and other salt levels, which we know it can do with an adequate fluid intake. I do recall hearing about some research that seemed to indicate that there were some people who were "salt responders", that is, their BP did go up and down based on the amount of dietary sodium, and others who did not respond with increased BP.

However, if the study didn't control for fluid intake, then maybe they missed an important variable.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
