Sodium is a mineral that is essential for the human body. It is involved in several physiological processes and is required for the proper functioning of various bodily systems.
It is important to note that while sodium is an essential mineral, excessive sodium intake can lead to health problems such as high blood pressure, which can increase the risk of heart disease and stroke. Therefore, it is recommended that individuals consume no more than 2,300 milligrams of sodium per day, and some individuals may need to consume less depending on their health status.
