This documentary uses interviews with cardiologists and narration to educate viewers about the high levels of salt in many foods and the health risks of excessive salt intake. Various camera shots and graphics are used to emphasize the surprisingly large amounts of salt found in everyday foods like bread, cereal, pizza, and peanuts. Scenes from a test on the salt content of foods and an experiment where the presenter tracks the effects of a high salt diet for a week aim to show that salt intake is generally worse for health than most people realize. The editing and sound design give the documentary a serious, professional tone to effectively deliver its message about reducing salt consumption.
