Why you must stop drinking Coke

We all know by now that Sugary drinks are considered a major contributor to health conditions such as obesity, type 2 diabetes and tooth decay. 


However very few of us actually know what happens to our bodies after we consume these drinks and that is is what I am writing about here

When I am at a certain stage in my Anatomy and Physiology teaching I introduce this information to my students and always get the same reaction- shock!

One researcher explains it beautifully in an infographic that shows what happens to the body within an hour of drinking a can of Coca-Cola.



A 12-ounce serving of Coca-cola contains approximately 10 teaspoons of sugar.


Coca-Cola ‘comparable to heroin’ in how it stimulates the brain’s reward and pleasure centers

In The First 10 minutes: 10 teaspoons of sugar hit your system. This is 100% of your recommended daily intake. The only reason you do not vomit from the overwhelming sweetness is  because phosphoric acid and other flavorings cuts the flavor and this  allows you to keep it down.

Within 20 minutes of drinking the Cola, blood sugar levels rise dramatically causing a burst of insulin. The liver then turns the high amounts of sugar circulating our body into fat.

Within 40 minutes, the body has absorbed all of the caffeine from the Cola. This causes a dilation in the pupils and an increase in blood pressure. By this time, the adenosine receptors in the brain have been blocked, and this prevents fatigue.

Five minutes later, production of dopamine has increased – a neurotransmitter that helps control the pleasure and reward centers of the brain. According to the infographic, the way Coca-Cola stimulates these reward centers is similar to the effects of heroin,  and so making us want more.


An hour after drinking the beverage,  the predictable sugar crash starts when  the blood sugar levels dip  causing irritability and drowsiness. In addition to these effects the water from the Cola will have been cleared from the body via urination, along with nutrients that are important for our health.

According to Naik, the author of this  infographic  these effects are  not only applicable to Coca-Cola, but to all caffeinated fizzy drinks.


In a press statement, a spokesperson for Coca-Cola says the beverage is “perfectly safe to drink and can be enjoyed as part of a balanced diet and lifestyle.”

At the end of the day  you have been given the facts …….SO YOU DECIDE!
