Salty taste’s unique chemistry has stymied the search for an effective salt alternative, and a more realistic goal might be a salty taste enhancer
It is well-known that overconsumption of salt is a major contributor to morbidity from hypertension-related illnesses globally, with governments and health organisations trying to encourage people to cut their dietary sodium chloride. However, attempts to get people to voluntarily lower their salt intake haven’t been terribly successful, and the biochemistry behind the taste of salt makes has made it exceedingly difficult to create an effective salt substitute.
