For pure drinking water, your best bet, from a practical perspective, is to filter the water coming into your own home. Unfortunately, fluoride can be quite difficult to remove from the water once added in. Reverse osmosis systems have typically been recommended to remove fluoride, but according to Green, many home systems may not be very efficient at this task. Commercial systems are typically much better, as they have redundancy features not found in smaller-scale residential models.
“[Y]ou’ve got to remember that the free fluoride ion, which is the part that we are concerned with… is smaller than the water molecule. You can’t… “filter” it out. You can’t screen it out because of the size, obviously… If you look at what the literature tells you, when you’re looking at reverse osmosis, they almost always say that if you had eight parts per million of fluoride [which is eight times higher than recommended]… they could bring it down to 0.9. So you get a 90 percent reduction.
But nobody says take your 0.9 and take it down to 0.1. Because what it’s basically doing is it’s taking out the fluoride compounds, which is still a good thing in some ways, especially if you had eight parts per million in it… but you’re still not getting out that free fluoride ion.”
To Distill or Not to Distill… That is the Question…
Distillation is another alternative. However, while distilled water is very clean, it also lacks structure and minerals, which is inadvisable for long-term daily use as it can deplete your body of essential trace minerals. Distilled water can be quite useful for short-term detoxification though.
Despite these drawbacks, Green prefers the distilled water over reverse osmosis, primarily because the amount of water that is wasted with the reverse osmosis (R/O) filtration systems. A reverse osmosis system can use anywhere between three to eight gallons of water to create one gallon of drinkable water.
I disagree with Green’s recommendation, as the example he gave is quite skewed. The typical level of fluoride in most fluoridated municipal water supplies is about one part per million, not eight, like the example he gave. So if you reduce that by 90 percent with an R/O system you are in relatively safe range of 0.1 parts per million. You can use distilled water to remove nearly all of it, but the distillation process is a form of more severe processing than R/O and it is more difficult to restore the water minerals and structure.
Add Fluoride, and Other Chemicals Become More Dangerous…
Interestingly, not to mention importantly, fluoride has the ability to affect other toxins and heavy metals, in some cases making them even more harmful than they would be on their own. For example, when you combine chloramines with the hydrofluorosilicic acid added to the water supply, they become very effective at extracting lead from old plumbing systems—essentially, together; they promote the accumulation of lead in the water supply!
“In fact the two of them have been combined, and I believe patented to be put together so that they could extract lead,” Green says. “… In fact, you’ve seen from reports in Washington D.C. about the lead content [in the local water] that this combination can have tremendous effects.”
