Why is that water is needed to live as opposed to alternative liquids? If coffee is just bean-flavoured water, why couldn’t you survive by only drinking coffee? If you were lost on a desert island and had only coffee, juice or soda to drink, could you survive?

We also ingest water from our food and produce some via breathing. Liquid foods can hydrate really well e.g. Tomatoes, Cucumbers, eggs etc…

Often times this is better overall for survival and health over simply drinking commercial or distilled water.
