Talk:Salt substitute

Kainit?
Does anyone know if the word kainit in the article is meant to be kainite or if it is meant to be "salts of potassium used in the manufacture of fertilizers" (from kainit on Wiktionary)? Thanks, Pupsterlove02  talk • contribs 16:22, 14 June 2020 (UTC)

But these are just different salts
Isn't the mechanism by which salt causes hypertension essentially osmotic pressure? Wouldn't any other salt, regardless of its specific minerals, still cause the same effect or at best, a lesser one?
