A happier aid for salt watchers: Mattel Electronics' new Diet Trac, a pocket computer specially designed to keep track of your cholesterol, caloric or sodium intake. Just tell it your nutrient goals, keep it up to date on what you are eating, and it will do the counting for you, down to the last milligram. Properly programmed, it will even send you a warning BEEP, BEEP, BEEP if an overdose of sodium is imminent.
