Animals will travel long distances to get salt. People will eat potato chips etc for the salt despite knowing they make us fat. Does anyone want chips without salt? A Dr I know emphasizes, “water, fiber, salt” as things we need.

In addition, we need the iodine they add to the salt. There is a yahoo group that tells about how important iodine is - here is a link if you are interested.

There is reason to believe lack of iodine causes more than thyroid problems - also there is evidence regarding breast and prostate health.

I found out about this from freeper spacejunkie (I think it is). If you start looking into this you find out some pretty interesting stuff.

Here is the direct link to the yahoo group. Really quite informative!

Putting fluoride in your water and swallowing fluoride from toothpaste is also a problem. The fluoride ions displace the iodine in the active thyroid hormone rendering it biologically inactive. Fluoride makes bones brittle as well.
