They say that drinking Coke (and other softdrinks like Pepsi) is bad for us. But do you really know what happens inside your body after drinking a can of coke? It might shock you, but here’s what happens:
THE FIRST 10 MINUTES
Your system is hit by a whopping 10 teaspoons of sugar from the coke that you drank. This does not cause you to immediately vomit though because the phosphoric acid cuts the flavor allowing you to keep it down.
Your blood sugar spikes which causes an insulin burst. This in turn causes the liver to respond by turning any sugar that it can get into fat.
At this stage, caffeine absorption is complete. Your blood pressure rises, your pupils dilate and your liver dumps more sugar into your bloodstream. The adenosine receptors in your brain are blocked which prevents drowsiness.
Your body then ups your dopamine production (a compound present in the body as a neurotransmitter) which stimulates the PLEASURE centers of your brain. This is actually how heroin works.
The phosphoric acid binds calcium, magnesium and zinc in your lower intestines which boosts your metabolism even faster. Couple that with high doses of sugar and artificial sweeteners and you get an increase in the urinary excretion of calcium.
MORE THAN 60 MINUTES
The caffeine’s diuretic properties come into play (it makes you pee). At this moment, it is now assured that you will release the bonded calcium, magnesium and zinc that was headed to your bones as well as sodium, electrolyte and water.
As the rave inside you dies down, you will start to have a sugar crash. This will cause you to become irritable or sluggish. Also, by now, you should have pissed away all the water that was in the Coke along with the valuable nutrients that your body should have absorbed to build strong bones and teeth.
