One of my best friends has recently had to go on prednisone, a synthetic corticosteroid immunosuppressant drug, side effects of which require people taking it to follow a low-salt (and/or sometimes high potassium or high calcium diet).
One salt substitute I like is dulse, a seaweed that is very common in Iceland and used as a snack and flavor enhancer. Dulse contains all the trace elements that humans need, including iron and B vitamins, fiber, a high protein content, and 15mg of sodium per teaspoon. Table salt has 2300mg sodium in a teaspoon. You do need a higher quantity of dulse to enhance the flavor of a dish, but not 150 times as much. It does taste like a seaweed, so can be an acquired taste. Some people think it makes a great bacon substitute!
Some folks substitute a spice/herb mix in savory foods, such as the following:
1 Tbsp ground cayenne pepper
1 Tbsp garlic powder
1 Tbsp onion powder
1 tsp dried basil
1 tsp dried oregano
1 tsp dried thyme
1 tsp dried parsley flakes
1 tsp dried savory
1 tsp ground mace
1 tsp freshly ground black pepper
1 tsp dried sage
1 tsp dried marjoram
1 tsp ground dried grated lemon peel
You just mix all of these together well (keep the mixture in a glass airtight container/spice jar in a cool, dark place, and it should keep for four months) and use as seasoning.
