He noticed some of his patients who were drinking distilled water were having mineral deficiency issues, so he recommended switching to filtered water instead of distilled water and the patients got better!

What did our ancestors drink? Also studies indicate that the healthiest societies drink hard water, which is heavily mineralized.
