Yep, totally right!  It is the fermentation that breeds the friendly bacteria that help us out.<p>Electrolytes are really just vitamins and minerals (Ca, Cl, Mg, P, K, Na, etc.) so you can get them from food :)<p>I do think filtered water is important because I respect the rule of bioaccumulation--if it kills small things, it&#x27;s usually bad for big things in that food chain.  The disinfectants used to treat tap water are poisonous to us at large doses, so I try not to consume even small doses if I don&#x27;t have to.
