Background: The intake of sodium, chloride, and potassium is considered important to
healthy nutrition and cardiovascular disease risk. Estimating the intake of these electrolytes
is difficult and usually predicated on urine collections, commonly for 24 h, which are
considered the gold standard. We reported on data earlier for sodium but not for potassium
or chloride. Objective: We were able to test the value of 24-h urine collections in a unique,
ultra-long–term balance study conducted during a simulated trip to Mars. Design: Four …
