Sugary drink (including Coke and Pepsi) consumption is associated with an array of health conditions such as type 2 diabetes, obesity, metabolic syndrome and tooth decay. According to the Harvard School of Public Health, people who drink 1-2 cans of sugary beverages daily are 26% more likely to develop type 2 diabetes.
There are approximately 10 teaspoons of added sugar in a single can of cola. The World Health Organization (WHO) recommends consuming no more than 6 teaspoons of added sugar daily, meaning drinking just one serving of cola a day could take us well above these guidelines
British pharmacist Niraj Naik shows the damage a 330 ml can of Coca-Cola can do to the body within 1 hour of consumption.
What Happens One Hour After Drinking a Can of Coke?
First 10 minutes: According to Naik, the intense sweetness of Coca-Cola as a result of its high sugar content should make us vomit as soon as it enters the body. However, the phosphoric acid in the beverage dulls the sweetness, enabling us to keep the drink down.
Within 20 minutes: Blood sugar levels increase dramatically, explains Naik, 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, causing a dilation of pupils and an increase in blood pressure. By this point, the adenosine receptors in the brain have been blocked, preventing fatigue.
Within 45 minutes: Production of dopamine has increased – a neurotransmitter that helps control the pleasure and reward centers of the brain. The way Coca-Cola stimulates these centers is comparable to the effects of heroin, making us want another can or bottle.
Within 60 minutes: A sugar crash will begin, causing irritability and drowsiness. In addition, 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, this is not only applicable to Coca-Cola, but to all caffeinated fizzy drinks.
“Coke is not just high in high fructose corn syrup, but it is also packed with refined salts and caffeine. Regular consumption of these ingredients in the high quantities you find in Coke and other processed foods and drinks, can lead to higher blood pressure, heart disease, diabetes and obesity.” writes Naik on his blog The Renegade Pharmacist.
“However a small amount now and then won’t do any major harm,” he adds. “The key is moderation.”
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.”
