Its refreshing, its sweet, and your brain screams out loud "YEEEEAAAAAHHHH" when we drink it - But that is only because our brain feeds on sugar! How about our body? Here is what happens in our bodies when we drink one can of bomba cola (literally, one can, and literally, bomba cola...)
First 10 minutes:
10 spoons of sugar enters our system. Phosphoric acid reduces the OP sweetness and this is why we do not throw out...
An explosion of insulin bursts within! Our liver responds to this by turning as much sugar it can to fat
Caffeine absorption is complete. Our pupils dilate, the blood pressure rises, and our liver dumps more sugar into your bloodstream. The adenosine receptors in our brain are now blocked preventing drowsiness.
Our body increases the dopamine production stimulating the pleasure centers of your brain. It's the same way heroin works (no, do not prefer heroin instead of cola)
The phosphoric acid binds calcium, magnesium and zinc in our intestine, providing a further boost in metabolism. This is compounded by high doses of sugar and artificial sweeteners, also increasing the urinary excretion of calcium.
The caffeine's diuretic properties come into play (make us have to pee). Now it is sure the bonded calcium, magnesium and zinc that otherwise would go to your bones, will go to the sewerage... Same happens with sodium, electrolyte and water ...
Since the buzz inside fades, we begin to have sugar deprivation. This may turn us to irritable or sluggish. By now, all the water that the cola had, along with with valuable nutrients that our body could otherwise have used to hydrate our system or build stronger bones and teeth, is down the drain...
