This was answered: yes, we could get enough from food without
deliberately added salt, and no, we would not have to eat meat to
get enough salt, although eating meat (or drinking milk) gets you
more salt than purely vegetable and fruit diets.

I gave you a ref -- if 600+ pages of experimental data is
"unsupported", screw you.

You were not getting "practically no salt", you were not adding
salt. BTW, 20 years ago it was virtually impossible to find any
canned vegetables without large amounts of sodium. It's still
difficult today, although a few brands do so.
