I regularly hear people say that eating salt is bad for the health and the heart etc. Why is this? I know that the bodies electrolites such as Na+, K+, Ca2+, Cl- etc. need to be balanced so ingesting too much NaCl will cause electrolyte imbalance, is that what people are referring to when they say salt intake is bad for the health? Can't that be counteracted by taking supplements such as potassium supplements etc?
