This documentary uses interviews and narration to warn about excessive salt intake and its health risks. It shows through tests and a participant's high-salt diet experiment that many foods contain much more salt than expected. Camera shots are used to emphasize the shocking amounts of salt, from a close-up of a salty snack to an extreme close-up of salt on a pizza slice. Graphics overlaying foods with their salt contents in an effort to clearly show that salt levels can be deceptively high and food labels sometimes misleading. The documentary aims to educate viewers that salt intake is rising and too much has negative health effects.
