Sodium lacing does something similar, as it’s biological uses and requirements are vast. Hell, prior to the modern age, salt was a precious commodity, to the point where many ancient militaries paid a salt ration to soldiers. If you look at most foods in their natural states, they are all VERY potassium rich, but very sodium poor. As such, it makes sense that we developed a taste receptor specifically for it.
