BS! Try the chlorine bleach they wash the silos with, the fluoride in the water they use and the pesticides they spray on grains.
***the fluoride in the water***
I am 77 years old and still have all my teeth. I blame it on natural fluoride in the High Plains well water we drank.
My wife from Texas says the same thing. Natural fluoride in the well water.
My Mother-in-law, had her perfect teeth pulled when a dentist she went to said those perfect teeth were causing her arthritis pains and pulling them would stop the pain. She had them pulled. The pains remained till she died decades later.
My mom was raised on natural well water in Tennessee. Her teeth were horrible and she had to have them pulled.
