Food has no flavour without salt
If you're used to foods that are high in salt, or adding lots of salt to your food, you could miss it when you first cut down. This is because our taste buds get used to high levels of salt. But our taste buds can get used to eating less salt in a few weeks and then you're more likely to enjoy food with less salt, or without any salt at all. If a food contains lots of salt this can hide more subtle flavours, so you might prefer some foods with less salt when your taste buds have had time to adjust.
