Is distilled water bad or good?

Hi, folks. I read this forum some times and I like it, like most here in curezone. I have been reading the Water Fasting forum too. They recommend distilled water and I drink it. I am about to buy my own water distiller. But I talked to this friend yesterday who told me "distilled water is bad for you because it's very acidic. Distilled water can give you cancer", he said.

This morning I decided to make the question about it in this forum. I like to get documented answers, whenever possible.
Please, answer this, ... Why is distilled water beneficial if it is so acid? Tweet
