Is cellular salt really that important?

Could you please tell me how important salt is to our system and how can we tell if we have a cell salt deficiency? Can we actually tell by a facial diagnosis?

The Health meets Food Team Says...

Sodium is extremely important to the operation of the human body and having a low serum sodium is a very dangerous condition. This is known as hyponatremia (hypo = low, natr = salt, emia = blood). It is difficult to have a low blood sodium level, as most diets are very high in salt and sodium comes from multiple ingredients. Most often hyponatremia is the result of drinking too much water and not from having too little salt in the diet.

Severe hyponatremia results in difficulties with nerve function as one of the most severe symptoms, and facial twitching could be a symptom. More severe manifestations include stupor, loss of consciousness, and seizure, and in extreme cases hyponatremia can result in death.

Thanks for writing.
