Salt is essential for us, that's why elephants trek for miles to lick natural salt. But...we have far too much salt available in our diets, and it has a deliciousness that makes us love it. In fact, salt masks the natural flavour of food; it becomes a bit of an addiction, so that we crave it. Catering pros know that it's addictive and that it also makes us thirsty, so they overseason everything. Excess of salt is associated with increased blood pressure. So salt, like sugar, should be avoided as an additive. We get both naturally in food, and we shouldn't add extra sprinkles. I find tea with sugar is disgustingly sweet, and ready meals are disgustingly salty. If you cut down on both you will learn to recognise its presence, and you will get a taste for natural food. Salt is a chemical (sodium chloride) and it's all the same stuff.
