Black coffee? Pretty healthy, just water and caffeine. 0 calories. 0g sugar. 0g sodium.
A Starbucks "White Chocolate Mocha"? 530 calories, 320mg of sodium, 69g of sugar per 20 oz "Venti" serving. That's twice as many calories as a 20 oz Coke, with twice as much sodium, and higher sugar levels.
Nobody is defending soda here. Just pointing out, this good idea needs to be applied consistently or people will switch from "unhealthy" soda to "healthy" coffee drinks or "healthy" fruit juices both of which can have scary-high sugar too.
I like the "color code" system they have in Europe[0]. You buy a soda and it has a red warning on the sugar/salt levels.
