Salt - too less is a problem; too much is a problem; ideal is between 3 grams to 5 grams

Scientific establishment got it all wrong about Salt, just like it got it all wrong about Fat. 

Salt - too less is a problem.
       - too less salt leads to high blood pressure & cardiovascular disease
       - sodium primarily helps by preventing infection
       - most of the sodium is stored in the skin, just under the skin
       - in an experiment, a dog's left leg was injured, after few hours most of the sodium got                    concentrated near the site of injury. Why? To prevent infection.
   
Just like most other nutritional things, too less is bad and too much is bad. e.g. Salt, Thyroid harmones

Did you know that driving your Sodium too low by limiting salt and drinking a lot of fluids is potentially fatal while it would be almost impossible to consume enough salt to kill yourself.  Every year numerous people, mainly babies given too much water, athletes who overhydrate and college students who drink too much beer kill themselves by driving their salt too low.  It’s called “Water Intoxication”.
