When you drink a can of Coke, you’re taking in 39 grams of sugar, 45 milligrams of sodium, some phosphoric acid, caffeine, and other ingredients, all from a 12-ounce serving.
While it’s refreshing at the time, your body is hard at work processing the beverage. Here’s what happens in the hour after you chug down a Coke, via a post by Wade Meredith at Blisstree:
20 minutes: You get an ‘insulin boost’ from the spike in your blood sugar. In response, your body’s liver turns any sugar it can into fat (which at this time, is a lot).
40 minutes: At this point, you’ve fully consumed the Coke’s caffeine. Your pupils dilate, blood pressure rises, causing your liver to start dumping sugar into your bloodstream.
45 minutes: Your body increases dopamine production, stimulating the pleasure receptors in your brain (this is how heroin works, too).
>60 minutes: The caffeine’s diuretic properties come into play. Your body starts evacuating bonded calcium, magnesium, and zinc that was headed to your bones as well as sodium, electrolytes, and water. Aka, bathroom time.
>60 minutes: As the madness in your body dies down, you’ll have the infamous sugar crash. You’ll become irritable or sluggish, which can last for hours afterwards for some people.
