Based on a 2,000 calorie a day diet for adults and children ages 4 and above, the acceptable average daily sodium intake is around 2,400 mg.
Keep in mind that the above does not apply to those who have high blood pressure or other heart related problems. If one does have high blood pressure or heart problems, most doctors will recommend a specific diet that balances sodium intake.
Sodium is VERY bad for anyone's blood pressure. It increases blood pressure. The American Heart Association (AHA) recommends an amount of 2300mg of sodium per day. Most Americans have a 5400mg per day sodium intake - 134% above the recommended daily limit. High diastolic blood pressure is also controlled by consuming less sodium.
It's good practice to check every food label for amount of sodium contained especially for processed foods. Also trying a hypertension diet is good for overall health as its is tailor made for 2300mg of sodium per day.
