Have you kicked your Coke habit yet?

I’m not talking about cocaine, but that tasty soft drink which used to contain it.

Back in October, Daily Health Post shared what happens to your body when you drink a Coke. Here is what they reported:

In the first 10 minutes: 10 teaspoons of sugar hit your system. (100% of your recommended daily intake.) You don’t immediately vomit from the overwhelming sweetness because phosphoric acid cuts the flavor, allowing you to keep it down.

20 minutes: Your blood sugar spikes, causing an insulin burst. Your liver responds to this by turning any sugar it can get its hands on into fat. (And there’s plenty of that at this particular moment.)

40 minutes: Caffeine absorption is complete. Your pupils dilate; your blood pressure rises; as a response, your liver dumps more sugar into your bloodstream. The adenosine receptors in your brain are now blocked, preventing drowsiness.

45 minutes: Your body ups your dopamine production, stimulating the pleasure centers of your brain. This is physically the same way heroin works, by the way.

> 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.

> 60 minutes: The caffeine’s diuretic properties come into play. (It makes you have to pee.) It is now assured that you’ll evacuate the bonded calcium, magnesium, and zinc that was headed to your bones as well as sodium, electrolytes, and water.

> 60 minutes: As the rave inside you dies down, you’ll start to have a sugar crash. You may become irritable and/or sluggish. You’ve also now, literally, evacuated all the water that was in the Coke. But not before infusing it with valuable nutrients your body could have used for things like hydrating your system, or building strong bones and teeth.

Scary stuff. Also check out what Antonie posted about sodas back in 2011.

  1. Excellent analysis! Hopefully this will awaken some parents who believe it is fine to give their children a cola. Then they wonder why their children act ADHD. And you simply wrote of the sugar, loss of essential nutrients and caffeine, not the chemicals related to this product. And Splenda is even worse! Great blog! Blessings,

    Hi guys. I’m a researcher studying clinical translational medicine. While I agree that coke isn’t that great for you, a number of points you make are unfair and some are just flat out wrong. For instance, in point #2. Your liver is the primary organ that responds to an increase in blood sugar. However, if you’re not overeating your liver will try to convert as much of that sugar as possible into a starchy storage molecule called glycogen. Comparing coke consumption to heroin is terribly misleading. The feeling of pleasure you get walking through a sunny park during springtime also acts in the same pathway as heroin. It’s the pleasure pathway. It’s well understood and ubiquitous. Everything uses it.

    The mechanism behind the increase in calcium excretion is simply incorrect. It’s not the phosphoric acid which causes the rise in urinary excretion. It’s the caffeine. In fact, phosphoric acid has NO impact on excreted calcium at all. Caffiene does, and is one of the only routinely ingested substances known to cause this phenomenon which does not contain calcium. Coke has about 1/3 the caffeine content of coffee,

    I am not an advocate for soda. I have no affiliation with soft drink corporations. I don’t drink the stuff myself, because even moderate soda consumption drastically increases your risk for type 2 diabetes. The point that I’m trying to make is that there are plenty of scientifically sound reasons why routine consumption of carbonated beverages can pose a risk to your health. But none of them are in your article. This misguided attempt to slam soft drinks exactly fits this style of writing: it’s pop-science.
