High blood pressure.
It may increase the risk of developing heart failure.
Benefits of table salt
Save water and fluids in the cells of the body.
Sodium and potassium work to control and store the water in the body. It is good for nerve action and transmission of the nerve signal. Sodium with other minerals creates the electrical impulses that control many of the body functions.
Sodium is good for the digestive system. Salt contains nutrients necessary for the digestive system, and it plays an essential role in the processes of digestion and absorption.
Tighten muscles and prevent muscle cramps.

Salt helps to absorb protein after digestion.
It stops bleeding, especially bleeding gums, and maintains the health of the mouth and teeth. A lack of salt in the body leads to many problems, such as disturbances in the fluid balance in the tissues and an imbalance in the acid-base balance.
