Judy, I think that's a principle straight out of the set of laws written by that fellow called Murphy! !
Soda Water is water with Carbonated. With Potassium Bicaronate no Sodium, well not usually.Mineral Water is either flat or carbonated and may have be naturally sourced or manufactured with large amounts of Sodium. It also may have Calcium, Magnisum , Strontum, Potassium, Nitrates, Chlorides and other minerals hence Mineral Water and a totally different taste from soda water being salty. Mineral water is not recommended for children, dieters or people with fluid retention due to the large amounts of salts in it particularly sodium. Flavoured Mineral Water has sugar and dyes as well.And some popular mineral waters have FLUORIDE as well. Which begs the question of why denounce fluoridated water when you drink Perrier? Not to mention the SULPHATES!Gert
