Before we find the winner, let’s shame the usual suspects. Mountain Dew? Around 46 grams per can. Dr Pepper? About 40 grams. Root beer? It can hit 45 grams. Basically, these are dessert in a can.
Even “fruit” sodas like Fanta or Crush can clock in at 44 grams. That’s like drinking a fruit salad that’s been dunked in a bag of pure sugar. Don’t do it, friend. Your future self will thank you.
