Is too much salt bad for us?

Salt, also known as sodium chloride, is about 40% sodium and 

60% chloride. It flavors food and is used as a binder and 

stabilizer. It is also a food preservative, as bacteria can’t 

thrive in the presence of a high amount of salt. The human body 

requires a small amount of sodium to conduct nerve impulses, 

contract and relax muscles, and maintain the proper balance of 

water and minerals. 

But too much sodium in the diet can lead to high blood pressure, 

heart disease, and stroke. 

The kidneys have trouble keeping up with excess sodium in the 

blood. As sodium accumulates, the body holds onto water to dilute 

the sodium. This increases both the amount of fluid surrounding 

cells and the volume of blood in the bloodstream. 

Increased blood volume means more work for the heart and 

more pressure on blood vessels. Over time, the extra work 

and pressure can stiffen blood vessels, leading to 

high blood pressure, heart attack, and stroke. 

It can also lead to heart failure.
