What happens to your body when you drink Coke

Your blood sugar spikes.

One regular can of Coke contains 39 grams of sugar. Yes, that is a lot to have at one time, especially from a drink, as there is a chance you're also eating something while you're sipping on this beverage. So you're consuming quite a bit of the sweet stuff. The second ingredient in Coke is high fructose corn syrup, after all. This one Coke can cause your blood sugar to spike, something that can have long-term side effects. In fact, a study in the journal Circulation found that consuming sugar-sweetened beverages was linked to the onset of type 2 diabetes. So with every Coke you drink daily, you could be increasing your risk of developing type 2 diabetes.
