How can mineral water have 0 calories?

Question

I understand that obviously water does not have calories, but the water we drink is not pure and contain other nutrients and minerals on it.

How can it still be 0 calories with these nutrients added? Is it really 0 calories or is the caloric content just extremely low (therefore they round it down to 0)?

In: 0

Answer 1

Minerals don’t have a calorie content. Your body uses various metal ions and salts for creating specific proteins and enzymes but it doesn’t use them for the base metabolic process.

You can reconfigure sugar molecules into fat molecules, but you can’t turn zinc into fat.
