People with low thyroid function are hypersensitive to chlorine and fluoride. For this reason, I can no longer swim in chlorinated pools. I have to also cut out from my drinking water, the traces of chlorine and fluoride left behind. I did consider getting an alkali water dispenser but I was not sure about alkali water. It looked to me like a fad, and not very natural.
Pure water however, is natural. The Big Berkey can filter even pond water and make it safe to drink. See HERE.
From now on, all water use for cooking rice and drinking will be from the Big Berkey.
