Hi! I recently heard that fluoride is very bad for you. I couldn't remember where I heard it, so I looked it up on the search engine. I typed in "fluoride is bad for you" and found lots of sites about it. Some doctors even had a site. Fluoride is a toxic substance. I read that it actually causes teeth to erode and crumble. Also, it dosen"t prevent cavities, only brushing prevents them. There are non-fluoride toothpastes in stores, such as wal-mart. I"ve been using "Tom"s of Maine" for awhile. It works fine and has a nice peppermint taste. City and town water often has fluoride in it. Plus, so much other stuff. Our's also has lots of clorine in it. I buy bottled water. I give it to my cats, also. Tylenol, is bad for you, too. It causes liver damage and even more so, if you drink alcohol. I can"t believe there's a commercial on t.v. that say's to buy it and that it's made with love! How horrible! Companies don"t care what they are selling you. Just, so they get rich. Slowly, people are finding out that mass produced, so called safe products are actually very bad for you. Look at how they are taking trans-fat out of food. Also, monosodium glutomate is in alot of foods. It is a type of salt that is very eroding to arteries. I always check labels. Regular table salt isn't the same thing, but you should not use alot of it. Well, I could go on and on! Natural is the way to go, because we are natural!
