Reverse Osmosis water

Hi Jeff,
We've been using an RO system, and I recently read that because it's a "pure" water (lacking in minerals), that it will leach minerals from metals--and that's why plastic tubing is used when setting it up.
But there's also talk that, because it's known as a "hungry" water, it shouldn't be used when cooking in stainless steel or used in plastic water bottles because of the leaching. I often cook in stainless steel (that's my pressure cooker), and we very seldom use plastic bottles, but I'd prefer not leaching more chemicals from the plastic. Then, of course, someone mentioned that the RO water leaches minerals from our bodies...
Not sure if this is just internet garbage, or if there's any truth to this. I feel rather foolish even asking about it.
