I would suggest you consider that the salt nannies are chasing a myth.
The healthy amount of salt intake is higher than the recommended levels from the gov. No way is the moochelle recommended 1500 mg daily correct, it is nutritional deprivation.
But, we must recognize that nannies must have something to obsess and lecture about, and the dietitians need to have their rules.
Also, except for those with kidney disease that prevents salt excretion or congestive heart failure that gets worse without salt restriction, everybody else handles salt by excreting what isn’t needed.
