I've heard conflicting info on distilled water.
Some say because it is so empty of anything, it easily absorbs whatever it is in contact with (like plastics, minerals in the body).
Some say it leaches minerals from the body.
Others say that it will NOT leach organic minerals (those from real whole foods) from the body, but will only leach inorganic minerals that the body should get rid of anyway.
Some say it won't leach any minerals, and that once minerals are bound in the body, they cannot be 'leached away' by any water.
Some say it is 'dead' and lacks any energy, and/or is acidifying.
Others say you can put energy/life and minerals back into it by putting a few grains of brown rice (or something similar) in, which also alkalinizes it (as would a slice of lemon peel).
I go with the last group. I put my distilled water in glass containers after it's done distilling, and put either a few crystals of Himalayan salt, or an actual crystal in (which is what I'm doing now).
Distilling does remove minerals, but if you eat a balanced diet, you should be getting more minerals in your food than what any kind of water would supply.
I have this distiller :

Re: Flouride. Flouride is a toxic substance. I don't want it in my water or in my toothpastes. Here's some info (a random site I found: I haven't read all the info, and can't vouch for its accuracy, but I've read quite a few bad things about flouride):

I also have a shower filter that filters out chlorine (another thing I don't want in my body!) and flouride.
