   Andrew explains that moderate salt intake is not harmful as long as enough fluids are consumed. The body can store sodium in various organs, but excess storage is not good for long-term health. Salt and thirst for salt are homeostatically regulated, and following your salt hunger and thirst, in most cases, is beneficial provided that it's in the context of eating healthy, nonprocessed foods on whatever backdrop of nutritional and dietary recommendations is right for you.
