Reacting to an article reporting few people use salt substitutes, even when they have high blood pressure, Instapundit wisecracks thusly, "That's because they taste terrible."
I happen to be one of those users of salt substitutes. These products swap potassium chloride for sodium chloride. The taste is similar but not identical.
In my experience his reaction is correct as an initial impression. I found I became accustomed to salt substitute relatively quickly, now I use it on meat, potatoes, etc. when the flavor needs a boost.
Some people never get used to the taste of sugar substitutes in colas. I did quickly and for years drank a couple of liters of diet soda daily.
My point is if you can adjust to diet soda - as many have with pleasure - you can probably get used to salt substitute. I certainly have, after fearing I couldn't. It beats eating bland food by a country mile, in my experience.
