DEAR DOCTOR K: I have high blood pressure. As I expected, my doctor told me to cut down on sodium. But he also told me to increase my potassium intake. Why?
DEAR READER: Sodium and potassium are two minerals that form salts. Your question reminded me of a patient I look care of long ago, who also had a high blood pressure problem. I asked her to substitute potassium salt for the usual table salt (which contains sodium). I'll tell you what happened later. People with diets high in potassium have lower blood pressures than those with potassium-poor diets.
