Your MD warns you that if you drink distilled water you will not be getting the minerals you need.
1) Ask your local public water supply for analysis report each time it is published.
You will notice the water does have some minerals in it. The MD assumes due to his "10 minutes" on nutrition in school that all minerals are the same.
He might as well tell you to eat dirt to get minerals. The particle size of the minerals in the water supply is much to large for your body to make use of. Indeed, it is in many cases, small enough for your body to determine what the mineral is and if you are short in this particular mineral your body may store it for future use. In the case of calcium (the most common mineral in the water supply) many people have the pain of arthritis and such disappear when they eliminate tap water and switch to distilled water.
Minerals that have been extracted from the soil are angstrom in size, the plants use them and then we eat them and get the benefit.
2) ( good luck on this one) Ask your MD to provide you articles (not sponsored by the filtering industry) explaining the horror of distilled water and the benefit of tap.

Your MD may suggest you supplement with a pill or a 'chew' or such.
If the mineral is chelated it is a mineral particle that is too big for your body to use and the industry has bound it to something else to trick your body into making some use of it.
