Question

How much salt is in the human body?​

Answer 1

Answer:

The human body contains many salts, of which sodium chloride (AKA common table salt) is the major one, making up around 0.4 per cent of the body's weight at a concentration pretty well equivalent to that in seawater. So a 50kg person would contain around 200g of sodium chloride – around 40 teaspoons.

Answer 2

Answer:

The percentage of salt in our blood is about 9 g/L -- or . 9 percent by weight. The acidity of our blood is tightly controlled by our body chemistry. Even a small change can lead to serious illness.
