"Your body tries to maintain a sodium/water concentration outside cell walls that's approximately the same as sea water. When you consume sodium, your body holds on to water to maintain the right ratio. Consuming 400 milligrams of sodium, the amount in a single gram of table salt, causes your body to retain an extra 4 cups of water, which equals roughly 2 pounds. Drinking more water flushes out the extra sodium, returning water levels to normal."
Hur sant det där är och hur mycket bro-science det där är, är en annan fråga.
