Even though people's salt levels can vary a lot from one test to the next, the average salt level across a whole group of people stays about the same over 15 years.

Similar Assertions

If you measure salt intake in healthy adults using multiple urine tests over many years instead of just one, you might get a very different picture of how much salt people eat — and that can change what we think about how salt affects heart and kidney health over time.

Measuring salt intake just once might make us think it's more or less harmful than it really is—using multiple measurements over time shows the risk could be very different, by as much as 85%.

If you eat a lot of salt—like 18 grams a day for 10 days—your body will flush out more salt in your urine and also have a bit more salt in your blood, which proves you actually ate the salty food they gave you.
