Oils ain't  oils. Mineral waters are also very different form one another.
Mineral water can be very low in minerals, far less than some tap water.
Some French/Swiss alpine water is preferable to much town water. In the UK
there are areas where parents are advised to buy low-solute bottled water
for the baby's formula, and it is not distilled water that is meant. Of
course such widely variant mineral levels can make a mockery of any idea
that artifically-feeding parents can calculate what their infants consume.
