I should have said "no added salt". Could we still get

THis part seems unsupported. Where did we find this "salt
appetite was a crucial need."??

About 20 years ago during some camping trip I lived on
canned vegetables for a week (and they had no added salt).
When I came home I had one taste of my mother's cooking
and I almost threw up-- nothing but salt. But then everyone
else insisted that it did not have too much salt, just
regular as always. So in 1 week had already adjusted to
practically no salt. I wonder how low one can go. That's all.

My guess is that nobody knows. Years ago it was thought
that THC made people hungry by causing a drop in sugar
levels. Nope. No effect. So they were making up a story
to explain something without testing it.

It's not like insulin. Besides, even if it were, we'd still
need to know what triggers these hormones. No go.
