"However, animals like us do not experience salt desire as a powerful, controlling drive as we do with oxygen, food and water." (from the article).

I disagree with that, especially when I was young. I would crave salt. I would lick my hand and sprinkle salt on it, then lick the salt off. I would break chunks off the salt lick block we had for our horses. I would lick the homemade play-doh my mom would make because it tasted like salt.

There's no substantiation for the claim in the article that we lack a salt craving. Apparently, the author hasn't, but I know a lot of people that do.
