Yes it is.......
Some folks, like myself need gobs of salt to maintain our electrolyte balance. If I were to cut back, I would fall on my face on the first hot day of summer.
Kidney function, sweating ability and a horde of other things have much to do with how much salt everyone needs, and no one person is the same as another.
Same thing with cholesterol, IMHO.
My BP is 90/60 in the am. My doctor told me to eat more salt. I have to have it first thing in the am or I feel like I'm passing out. Familial. My dad is the same way.
