Answer:
Potassium chloride tastes like salt, and is among the modern commonly used salt substitutes for table salt (sodium chloride) for those on a low sodium diet, but salt substitutes have their own sets of negative medical side effects.
Alternately, get used to eating with less & less added salt, until you've stopped adding any. Adding pepper, Chile sauce, or the spice /condiment of your choice can help you stop adding salt.
