7. Phosphoric Acid
Phosphoric acid – also known as orthophosphoric acid – is used as an acidifying agent to add tartness to cola. This, combined with the huge amounts of high fructose corn syrup mixed in, both mask and balance the acidity of carbonated drinks.
A study was published in the American Journal of Clinical Nutrition, which provides reasonable evidence to support the association between consumption of cola and lower bone density. Some studies claim that phosphoric acid lowers the levels of calcium. Moreover, a team of scientists from the US National Institutes of Health has found that drinking two or more colas a day doubles the risk of kidney stones.
Now, Coca-Cola contains various acids but as we discussed earlier, none are potent enough to dissolve a nail, tooth or penny in four days.
8. Citric Acid
Manufacturers commonly use citric acid as a preservative and flavor enhancer. However, contrary to what you might expect, 99% of the citric acid added to drinks and foods does not come from citrus fruits. Extracting citric acid from lemons, limes, oranges, and grapefruits is far too expensive for the corporations. And so we get the artificial stuff that you consume every time you sip your Coke.
However, any concerns that the citric acid in Coke is bad for you is both erroneous and the result of an undeserved bad reputation. Basically, a study in the British Dental Journal claimed to find a strong link between carbonated beverages and tooth erosion. Consuming at least four glasses of carbonated soft drinks a day was associated with a 252% higher risk of tooth problems in 12-year-olds, and a 513% higher risk in 14-year-old children. This is almost certainly not taking other factors into account, as Coca Cola has a pH of 2.525 (Diet Coke has 3.289,) and while battery acid (an actual corrosive) has a pH very close to 1. In short, citric acid is a very weak acid, and comparing it to something truly destructive has nothing to do with reality.
And now we get into more harmful territory …
According to research carried out by the French National Institute for Consumer Affairs, more than half of well-known colas contain tiny traces of booze. Don’t worry though; you would have to drink something like 13,000 cans of the stuff to even come close to being legally drunk. Scientists tested 19 different brands and discovered levels of alcohol as low as 10 mg/liter.
As expected, the French study sparked quite a controversy, and divided the Muslim community into pro- and anti-Coca-Cola campaigners. While some Muslims believe that it is irrelevant if the product contains 0.001% alcohol or 100% – it is haram either way – others find it acceptable, since small traces of alcohol can be found in a lot of things, including many fruit-based products.
10. High Fructose Corn Syrup
High fructose corn syrup was introduced to the American market in 1967, and its consumption has exploded ever since. It is the main ingredient in Coca Cola, with over 18 cubes of the stuff per liter. This is … not a good thing.
Food safety agencies from all over the world classified high fructose corn syrup as safe, and no different from regular old cane sugar. Problem is, both HFCS and cane sugar can be dangerous, especially when consumed in high doses (which Coca-Cola’s marketing team obviously wants to be the case.) A research team from Princeton University has demonstrated that the long-term consumption of HFCS leads to weight gain, abnormal increases in body fat, and a rise in triglycerides. These are well-known risk factors for diabetes, cancer, high blood pressure, and coronary artery disease.
To preserve the health of its people, Venezuela banned Coca-Cola because the so-called “liquid candy” was simply too unhealthy. As delicious and refreshing as Coke can be, perhaps it’s time other nations considered the same.
