I went low salt long before my heart problems, my cardio people laugh when they tell me my sodium is a little bit low because I say anchovy pizza time.

Very common question people ask me is why do processed foods use so much salt, it isn't needed as a preservative any more in most cases.
Well the answer is simple it adds flavor and is far cheaper than herbs and spices so they use more salt and less herbs and spices.
Save the salt intake for things that really need salt.
