I've meant to tell you this earlier, but I'm glad you drink only distilled water, too! My family and I've been drinking it for 20+ years. Something that many do not think about is rinsing their mouth and cooking with distilled water. I learned this from my doctor when I was going through torment with those chemical sensitivities issues and Amalgam removal.
VERY LOW LEVELS will do harm. In his post, Dr. Judd said, "Fluoride at very low levels destroys at least 66 out of 83 enzymes... Fluoride in the gels used (inappropriately) to harden the enamel is extremely toxic at a concentration of 13,000 ppm (1.3%)"
As old as I am and still an idealist, so it continues to shock me learning about people being so viciously greedy to profit off the misery and death of others. Fluoride, amalgams, nicotine, unnecessary surgeries, and the list goes on and on of what humans will do to other humans for money and power. Life is sacred, but somewhere some have not learned that respect.
Thank you for your info and encouragement - always timely!
