Recent headlines have already told us that drinking any kind of soda is bad for you, but below is some food for thought about what happens in your body after you consume a Coke (courtesy of Better Health News). It probably applies to any kind of cola. It'll make you think before you grab that next cold one.

WHAT HAPPENS WHEN YOU DRINK A COKE

In the first 10 minutes:
Ten teaspoons of sugar slam into your system. (100% of your recommended daily intake.) Instead of vomiting from the extreme sweetness (which would most likely occur if you actually somehow managed to ingest ten teaspoons of actual processed sugar all at once), phosphoric acid cuts the flavor allowing you to keep it down.

At 20 minutes:
Your blood sugar spikes, which causes your pancreas in turn to emit an insulin burst. Just like a domino, your liver will in turn respond to this by changing any sugar it can get its hands on into fat. (And you've just ingested plenty of sugar, so your liver is finding a lot to work with.)

At 40 minutes:
Your body has completely absorbed the caffeine by now. Your pupils dilate and your blood pressure rises. You liver responds and releases more sugar into your bloodstream.

At 45 minutes:
The dopamine production in your body is increased, which stimulates the pleasure centers of your brain. Heroin, and most other drugs, work in exactly the same way.

Over 60 minutes:
The phosphoric acid binds calcium, magnesium and zinc in your lower 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.

Over 60 minutes:
The caffeine?s diuretic properties come into play and you'll have to run to the bathroom. It is now assured that you?ll evacuate the bonded calcium, magnesium and zinc that was headed to your bones as well as sodium, electrolyte and water.

Over 60 minutes:
As the party inside of you dies down you?ll start to have a sugar crash. You may become irritable and/or sluggish. You'll also lose valuable nutrients your body could have used for things like hydrating your system or building strong bones and teeth.
