Based on a 2000 Calorie Intake; for adults and children 4 or more years of age the average daily sodium intake for Americans age 2 years and
older is more than 3,400 mg. Americans are consuming substantially more sodium. Since the
1970s, the amount of sodium in our food has increased, and we are
eating more food each day than in the past. The majority of the sodium consumed is from processed and
restaurant foods; only a small portion is used in cooking or added
at the table. Research strongly shows a dose-dependent relationship between
consuming too much salt and raised levels of blood pressure.
The good news is that when salt intake is reduced, blood pressure begins decreasing
within weeks on average.
