One of the first things I did as I learned more about health was to stop drinking tap water and do my best unless I am dying of thirst not to buy bottled water in plastic.
For those with any thyroid issues (and it is an epidemic!), it is the fluoride and the fake estrogen that we should most adamantly avoid.
Here is why:
Fluoride - knocks iodine off the cells--so it cannot accept the thyroid hormones that you are taking in your medications.
"Fluoride’s ability to damage the brain is one of the most active areas of fluoride research today. Over 300 studies have found that fluoride is a neuro-toxin" (a chemical that can damage the brain).
Plastic water bottles have fake estrogen in the plastic which reduces lithium in our bodies which is needed for stable moods and is required for getting B12 into our cells. This reduction of lithium causes brain shrinkage (I don't know about you but I cannot afford any smaller of a brain!)
Here is a list of heavy flouride water brands:https://www.davidwolfe.com/bottled-water-fluoride-brands-avoid/. Have you been drinking them?
Plastic also increases TBG or thyroid binding globulin--which binds up T4 which means there is none available for cells to convert to T3 which in turn lowers T4 and T3. YIKES!!
Where else does fluoride hide:
Statin drugs contain fluoride
Many antibiotics like Cipro have fluoride
Many antidepressants like Prozac have tons of fluoride
Here is a link to a list of drugs that have fluoride: http://www.slweb.org/ftrcfluorinatedpharm.html. You have to click on the drug category and it will list the drugs. Prozac for sure, many PPI's ( drugs for Heart Burn or GERD) have it.
So this is one thing you can do for yourself is to STOP drinking TAP and BOTTLED WATER.
I use Walmart Reverse Osmosis water for .37 per gallon. I use a 5 gallon non BPA container and add ConcenTrace Trace Mineral Drops because we need the minerals and Reverse Osmosis water takes all the bad stuff out but takes out the minerals as well. This is not the best option, but it is the easiest and most cost effective for me at this time. Here is a link to the drops: http://www.vitacost.com/trace-minerals-research-trace-mineral-drops-concentrace-8-fl-oz-4. Health food stores may have these minerals cheaper.
I highly recommend the Berkey water filter system. It is most recommended by the circles I travel in and it uses tap water which is very convenient. Here is a link to check out hte Berkey systems available :https://www.berkeywaterfilter.com/product/big-berkey/.
If you do this one thing it could have a huge impact on your overall health!
