No, usually it has to do with water retention which is bad for people with high blood pressure. Recent studies have shown this to not necessarily be true.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?
I'm an old guy with a blood pressure problem, so I've talked this one over at length with my doctor. I need some salt for my body to function properly. The trouble is that my normal diet provides much more than I need. So he told me to cut down.
Then I get hauled to the emergency room in great pain, where they determine that I don't have enough salt in my system. They fix the problem by giving me salt pills. Then I'm OK.
So the discussion with my doctor continues. He finds that I often work hard out in the summer heat, and that when I do I sweat a great deal. Two or three gallons of sweat is common, and sometimes I drink up to five gallons of water without having to urinate. So he tells me that for my off nominal behavior, I need more salt. He recommended drinking one small bottle of a particular sports drink with each gallon of water to keep my electrolytes at a safe level. Then on days when I'm not working outside in the heat, go back to a minimum salt diet. This has worked well.

We need some amount of salt in our diet. It is essential. You will die without any salt intake. However, you can also die with an extreme excess of salt intake, and a lesser (but still excessive) amount of salt intake is bad for your health.Our taste buds specifically identify salt, and we also crave salt sometimes. If it was bad for our health, I don't think this would be the case.
I'm not sure where you're getting your information. Potassium intake is extremely important.taking potassium doesn't do anything. The kidney in general has a great propensity to retain sodium and dump potassium. Sodium will be retained at the expense of all other eletrolytes
A diet that includes natural sources of potassium is important in controlling blood pressure because potassium lessens the effects of sodium.
In healthy individuals, the kidneys respond to excess sodium by flushing it out in the urine. Unfortunately, this also removes potassium. If potassium levels are low, the body tries to hoard it, which also means hanging onto sodium. Water follows sodium, leading to an increase in the amount of water in the body and the volume of blood in circulation. Blood pressure climbs, and the heart must work harder. Excess sodium blunts the ability of blood vessels to relax and contract with ease, and may also overstimulate the growth of heart tissue. All of these responses are made worse by low potassium intake.
In some people, especially those with high blood pressure, heart failure, or impaired kidney function, the kidneys hang onto sodium no matter what, further complicating the picture.
One way to flush sodium out of the body is by getting more potassium.
