No, it isn't.
If you have certain types of health problems you might want to keep an eye on how much of it you eat but salt is necessary for life.
A friend of mine has Hyperkalemia (high potassium) which means that the "low salt" stuff is poison to her and she has to be careful about her intake of things like, apples, bananas, brown rice, beans, orange juice, potatoes and a whole host of other stuff that is considered "healthy food".
I love salt and I eat a lot of it, if I cut down then I start feeling ill and my blood pressures drops dangerously low. This happened a couple of times when I let someone talk me into a "healthy low salt diet." My doctor told me that if she ever heard of me doing that again she was going to slap me.
You body knows what it needs and no paper pushing bureaucrat should be able to tell you what you should or should not eat.
