First, listlessness. The main component of salt is sodium, which is an essential substance for transmitting information in the nervous system of the human body. Muscle contraction and heart beating are closely related to sodium ions. Of course, when salt is lacking or salt intake is insufficient, it will lead to listlessness and listlessness, which is not conducive to normal work and life.

Second, increase the incidence of cancer. When the salt intake is insufficient, the acidity content in cells will rise sharply, which will damage human DNA cells and induce cancer.
