Since we're on the subject of fluoride, I thought I'd give a heads up to those 
with thyroid problems.  Several months ago I too read that boiling water (not 
distilling) increases the fluoride.  I don't have any of the materials I read 
back then to quote from now.

But having read that fluoride interferes with the thyroid, I have been drinking 
only distilled or reverse osmosis water and then adding minerals (ConcenTrace). 
 For coffee or hot tea or any other hot or cold drinks I only heat the small 
amount of DW or RO water that I need at that time.  I should probably also be 
using DW or RO water to cook vegetables as well, but that requires haulin lots 
of gallon jugs from the store.

I think I will research some RO units for under the sink as I have time this 
week.  Meantime, anyone with suggestions on the best bang for my buck on RO 
units, or any other suggestions on best utilizing the water and avoiding 
fluoride for best health, would be most welcome!

Thanks in advance!
