Answer on @Quora by @AdrianaHeguy to Is it medically accurate that a diet lacking – Xochielt Sanchez

Answer by Adriana Heguy:

Salt (sodium chloride) is an essential nutrient because it is necessary to maintain osmotic pressure in cells, and for many cellular functions, including nerve conductance and heart function. However, it's virtually impossible to consume too little salt, even if you do not add table salt to foods, because basically all foods contain some degree of salt (sodium chloride), and not just meats and seafood, but also vegetables. It's totally possible to never cook with any table salt, and still consume enough salt, because very little of it is necessary for its biological functions.

However, there are serious conditions that result from hyponatremia (low salt in the blood). Hyponatremia can result in death. It has happened to marathon runners who drank too much water and sweated profusely, thus never replacing necessary electrolytes. It is an extremely rare occurrence. Profuse diarrhea and vomiting can also result in hyponatremia. Kidney failure and congestive heart disease as well.

Symptoms are muscle spasms, nausea, headache, seizures, altered mental state. More information can be found here: Low salt or sodium in the blood (hyponatraemia)

In other words, normal, healthy people with a normal diet do not need to worry about becoming "stupid" from eating too little salt. Reading too many internet articles from non reputable sources is more of a concern. Asking the question in Quora is a great antidote!

If you have any health concerns, consult a physician as soon as you can, of course.
