Mountain Dew Zero Sugar vs coffee and espresso

How the number behaves

Sodas list an exact caffeine number because caffeine is a measured additive: every 12 oz can of Mountain Dew Zero Sugar carries the same 68mg, unlike brewed coffee, where the beans, dose, and brew time move the figure around. That predictability is the one real advantage a can has over a cup: you always know exactly what you drank.

The mistake people make is treating it as caffeine-free because it is "just a soda." At 68mg per 12 oz can, it takes about 6 servings to reach the 400mg FDA reference, but every serving still counts toward the same daily total as your coffee does.
