The Dietary Guidelines for Americans 2015 address sodium intake in detail. The average daily sodium intake for Americans is 3,400 milligrams per day, an excessive amount that raises blood pressure and poses health risks.
Some people are more sensitive to the effects of salt than others. The guidelines also recommend that, in general, individuals with hypertension, blacks, and middle-aged and older adults should limit intake to 1,500 mg of sodium per day. The exceptions to this guideline are people whose doctors have put them on a diet that requires even less sodium because of a medical condition.
