Question: How much salt is in the average human body

Aimee Egglestone answered on 19 Nov 2019:

There’s a few different kinds of salt in the human body, but thinking only about the table salt variety it usually makes up about 0.4% of a person’s body weight (this is about the same as is in the sea which is why you float better on sea water than pool water). For a person who weighs 50kg this means there is about 200g (40 teaspoons) in their body!
