Well, if you have talked to your doctor and he checked your electrolytes, it seems your body is able to balance your salts. Some health conditions people crave salt, I think Addison’s disease is one of them, I think Bartter’s is another (but low potassium likely would have shown up in preliminary blood tests for Bartter and I think that is usually discivered in early childhood? Not sure). A general doctor would probably not assess you for Addison’s, and as I said Bartter would be unlikely I think to become symptomatic all of a sudden. Again, not sure, I am not a doctor, just going on what little I know about each.
If you want to lower your salt intake eating less will eventually have you craving less. I once tried to cut my salt, because my mom said I was eating too much and my next blood test showed my sodium as too low, which can be dangerous. It is the only time in my life my electrolytes have been off, so I don’t worry about cutting my salt too much. But, everyone is an individual when it comes to health. Count up how much sodium you are actually consuming for a couple of days. My husband says he doesn’t eat a lot of salt, because he doesn’t add it to food. That’s ridiculous because I cook his food and I add a lot of salt in my cooking. He is basically clueless about his salt intake.
