On it’s own nothing the body needs quite a lot of it. But it can be a problem if your diet includes excessive quantities.

Edit: Saying a food is healthy or not IMO really a question of how well it fits into the widest selection of current diets and lifestyles. Drinking say 1oz of sea water it generally fine and if people where frequently salt deficient then it could be considered healthy, but as insufficient salt intake is not a common problem and excessive salt intake is occasionally one I don’t think we can really consider sea water as healthy.

Similarly dietary cholesterol has minimal impact on most people, but overall excess is more generally going to be an issue simply due to the small population that is at risk. As such I think we can say lower cholesterol chicken is a net positive overall unless we know more about the specific person involved.

Well that is true for almost anything including water.

What is the problem you are referring to?
