Does Caffeine Contain Very Small Amounts Of Protein?
I notice that a 12-ounce can of Coke contains 0.3 grams of protein. What? Can that be from caffeine? The caramel coloring could also be the source. I checked other caffeinated beverages, and they too had very low amounts of protein. Doing a Google search for caffeine + protein doesn't reveal a definitive connection.
