WE know fluoride is supposed to help children’s teeth but what is wrong with toothpaste and a good brush? So many brands to choose from should be enough.

Also, as far as I know, have not heard or read anywhere – what effect does fluoride have on the food chain? After all, I guess animals will be drinking the water.

Will that mean we are all doubledosed in fluoride when we eat meat or daily products?
