August 1, 2012

Q. If you exercise daily (and sweat), can you have more than the daily recommended limit of sodium?

It is recommended that most adults ages 50 or younger have no more than 2,300 milligrams (mg) per day of sodium. For people 51 or older, for African Americans of any age, and for people with diabetes, high blood pressure, or kidney disease, the recommended level is 1,500 mg per day.
