Now, I do not think that everyone should have a salt lick in their home; but, I'm pretty sure we can handle a little salt, since the inside of our body seems a bit "salty".
In my 62 years I’ve seen “Salt will kill you” , “Coffee will kill you”, “Meat will kill you”, “Soy will kill you”, “Sugar will kill you”, and these have all been debunked and sometimes ‘rebunked’. Call me when someone says “Tobacco isn’t so bad.” Then I’ll know that science is back. Until then, it’s politics.
