" 'Natural mineral water' is covered by less comprehensive regulations than tap water and may contain higher concentrations of solutes such as nitrate, sodium, fluoride and sulphate which might lead to solute overload if these waters are given to young infants."
The tap water that we drink every day contains only chloride and flouride - all minerals are removed during the treatment process. However, with mineral water the composition is unchanged - extra minerals are neither added nor removed from it.
In guidelines sent to health authorities (Ref.6), the Department of Health recommends:
"Check the label and avoid using water in bottles labelled 'natural mineral water' - they are not required to meet all the standards for tapwater and other bottled waters."
