Ask the doctor: Should I get more potassium from a salt substitute?
Q. You've emphasized that people generally eat too much sodium and not enough potassium. Could I solve both problems at once by replacing my regular table salt with a substitute containing potassium?
A. Many Americans do eat too much sodium and not enough potassium. Your condiment approach to the sodium/potassium balancing act might help, but most people's excessive sodium intake comes largely from processed and packaged foods. So a far better strategy would be to replace salt-saturated prepared foods with fresh fruits and vegetables, almost all of which are high in potassium and low in sodium, and which offer other health benefits as well.
