Salt (sodium chloride) is a necessary component of life and consists of two ions, sodium and chlorine. Sodium and chlorine are responsible for balancing body fluids between the different compartments inside and outside the cell.

Sodium controls blood volume and consequently blood pressure, assists in transportation of neural signals, supports muscle function, ensures rhythmic beating of the heart and achieves electrolyte balance. Sodium losses are noticed when sweating, in athletes and in individuals with gastrointestinal complications such as vomiting and diarrhea.

Nowadays much of the attention
is drawn on sodium overconsumption
instead of sodium deficiency. However
one should understand that the daily
intake of the Recommended Dietary
Allowance (1,500mg) is vital.
