The only thing that I know about salt is that it causes the body to retain water. Once I went to my dr...years back. He pressed his thumb on my shin and left an indention, asked what I had for lunch (cheeseburger & fries
) and told me to cut back on the salt because I was holding water. He said if you press on your leg and the indention stays you are holding water and that mine was caused by high sodium.
