Many/most humans like certain types of food/drink because of the psychological/physiological responses we have to consuming them. Some examples:
- We like sugar because it is very energy-rich (and is relatively scarce in nature).
- We like salt because it is one of the essential building blocks of our cells.
But why do we like drinking carbonated drinks? (Soda drinks like Cola, Fanta, Tonic, Dr. Pepper, etc. but also sparkling wine, cider, champagne) Except in some very rare, special springs, carbonated water does not occur in nature. Why do we like drinking it so much?
