Here is a curious article called What Happens To Your Body If You Drink A Coke Right Now? The descriptions of metabolic processes lack context, so it’s unclear how normal or abnormal the body’s reaction to Coke is. Since I lack expertise in this area, I can’t offer an informed opinion on the effects of Coke vs. a Krispy Kreme donut or a spoonful of peanut butter. However, I don’t believe that the effects of any Coke-like beverage are any too good.
I pretty much stopped drinking the stuff a few years ago. When asked why, I usually respond that what amounts to sugar water no longer appeals to me. (It still tastes good to me, but it doesn’t help me to eat healthily.) And as the article says, buried down in the footnote:
Coke itself is not the enemy, here. It’s the dynamic combo of massive sugar doses combined with caffeine and phosphoric acid — things found in almost all soda.
I admit, though, that it’s hard to escape soft drinks in one’s diet. They’re bundled with meals, mixed with alcohol, and closely associated with a variety of activities and behaviors. For instance, I can hardly bring myself to see a movie in a theater without also getting a popcorn/soft drink combo. Those combos usually come with 32 oz. drinks and free refills. No wonder why everyone queues outside the restrooms after the movie lets out.
