If you missed our Twitter party the other night (the one on toxins in your water with Dr. Alan Greene), here is the complete transcript.
Need it even simpler? Here are the big takeaways:
1. Tap water–even in areas known for “good” water–often contains a range of contaminants.
These might include heavy metals, pesticides, pharmaceuticals, hormones, and of course chlorine and fluoride. The pesticide Atrazine is of particular concern, and can be found in the tap water of 30 million Americans. Animals who ate identical diets and burned the same amount of calories weighed 10 percent more if they had Atrazine in their water!
2. Chlorine is bad stuff.
Chlorine is added to municipal water to kill microorganisms (which is good). But it’s linked to everything from hormone disruption to cancer. It should be filtered out after it’s done its job. Chlorine also is inhaled as steam in the shower, you should get filters for your showerheads, too.
3. Fluoride belongs in toothpaste, not water.
A recent Harvard study showed that fluoride exposure can cause as much as a 7-point drop in IQ. Fluoride stops tooth decay but is best in toothpaste and then spit out. (Special filters will take out fluoride.)
4. Bottled water is often worse than tap water.
Bottled water is usually stored in plastic, which we know leaches toxins. While tap water is frequently tested and treated, and you can find info about your local water online, this isn’t true for bottled water, and most isn’t treated with advanced filtration. If you must by bottled water, Penta Ultra Purified Water scores high marks from the Environmental Working Group.
5. Pitcher filters don’t do much.
Plastic pitcher-style filters don’t do much besides improve the taste and appearance of water. Pitchers also means your water sits in plastic, and BPA-free doesn’t mean anything, (in fact it can be worse than BPA!).
6. The best filter choice is a carbon filter.
7. Drink from glass or stainless steel.
