Top 10 Controversial Ingredients

Found In Coca-Cola

 

Coca-Cola has been at the center of controversy ever since the fizzy drink first graced the shelves. Myths and rumors are abound about the ingredients used to make Coke. While some of this is either unproven, or blown out of proportion, many of these stories are quite true, and quite disturbing.

Let’s take a look at 10 of the most controversial ingredients/contaminants found in Coca-Cola and analyze what scientific studies reveal. This is not so much to scare you into pouring all of your Coke down the toilet, but more to encourage you to inform yourself about what you are drinking.

10. Alcohol

alcohol-coca-cola

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.

9. Citric Acid

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 …

8. Phosphoric Acid

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.

7. Mercury

mercury

The Institute for Agriculture and Trade Policy has discovered that 9 of 20 tested samples of commercial high-fructose corn syrup were contaminated with mercury. The Institute also found that 55 kid-friendly foods and soft drinks contained total mercury, which is any combination of inorganic, organic or metallic mercury.

As you can see, there are plenty of products with higher mercury levels than Coke, but the level is still fairly high:

mercury-levels

If you are asking yourself how the heck mercury would have gotten into high-fructose corn syrup, here’s a possible answer: mercury-grade caustic soda and hydrochloric acid are primarily used to separate corn starch from the corn kernel, and to adjust the pH level of the process. The contamination seems to occur when mercury-grade caustic soda and outdated mercury cell technology are used in the production of HFCS.

The good news is that mercury-contaminated HFCS is a completely avoidable problem, since mercury-free versions of the two reagents are available.

6. Sodium Benzoate

Sodium-Benzoate

Manufacturers commonly use sodium benzoate as a preservative, and you can find it in carbonated drinks, pickles, soy sauce, dressings, jams and fruit juices, cosmetics, medicines, and so on.

The International Programme on Chemical Safety, and other regulatory bodies, found no adverse effects in humans at doses of 650 to 830 mg. per day. The effects of higher amounts are unknown, but almost certainly bad, judging by the increased obesity rates all over the world. Sodium benzoate does not occur naturally in foods and drinks. Manufacturers try to confuse consumers by masking these preservatives with labels that say antimicrobial nutrients.

If processed foods are not part of your daily diet, there are no risks, but let’s be honest, it is. We all know what an integral part of the modern lifestyle processed, convenient foods are. Coca-Cola is in the process of phasing out the controversial additive in the UK, due to consumer pressure, but fruit-juice based products will still contain it.

5. Benzene

benzene

Benzene is a natural constituent of crude oil, gasoline, and tobacco smoke, and has been classified as a class A human carcinogen. Does that sound like something you want in your soft drink? Probably not.

Research scientists Glen Lawrence and Lalita Gardner described the exact chemical reaction that takes place between ascorbic acid (Vitamin C) and sodium benzene to form benzene. The groundbreaking research appeared in the early ‘90s in the Journal of Agriculture and Food Chemistry.

In 2005, the FDA found that 10 samples of soft drinks out of 200 contained benzene levels over 5 parts per billion, which is above the legal limit. All 10 soft drinks have either been reformulated to meet standards, or just plain taken off the market.

The next year, the FDA released preliminary results for 100 soft drinks. Most of them contained legal levels of benzene, but four products exceeded 5 ppb. Two of the drinks contained benzene 18 times higher than permissible.

According to studies conducted by the Environmental Working Group, there are about 5 and 138 PPB of benzene in Coca-Cola. And, as the American Petroleum Institute stated, “It is generally considered that the only absolutely safe concentration for benzene is zero.” Drink up!

4. 4-methylimidazole (4-MEI)

4-methylimidazole

4-methylimidazole is a byproduct that occurs in caramel coloring, and may also be formed in the cooking, roasting, broiling, grilling or other processing of some foods and beverages. The National Institute of Environmental Health Sciences has identified the carcinogenic 2-and 4-methylimidazole as undesirable byproducts in many foods, and no limits are currently set on the quantities of caramel coloring used in foods and beverages.

The roughly 130 mg of 4-methylimidazole in a 12-ounce cola is four times higher than the NSRL-recommended limits. Coca-Cola has agreed to change, in some states anyway, the manufacturing process. Mainly because not doing so would have forced them to put a cancer warning on the label, and nobody needs that kind of publicity.

It is, quite frankly, disturbing how companies get away with marketing caramel-colored products as natural. From the legal point of view, the International Food and Agriculture Organization’s Codex Alimentarius does not have a standard for natural foods because it does not recognize the term natural (probably because literally anything can be deemed something as vague as “natural.”) Perhaps it’s time to crack down on this.

3. Aspartame

aspartame-packets

Aspartame is a low-calorie artificial sweetener, about 200 times sweeter than sugar. It is added to weight control products, soft drinks, yogurt, cereal, chewing gum, cooking sauces, desserts, sweets, etc.

Of course, just because its popular, doesn’t mean it’s good for you. Diet Coke contains about 180 milligrams of aspartame per 8.3-ounce serving. The bitter truth is that weight control products ruin the body’s ability to count calories. Artificial sweeteners like aspartame, when combined with said diet product, mess up the brain’s chemistry and stimulate appetite. Result: more eating, and more weight gain.

In addition, the Ramazzini Foundation released a three-year study confirming the link between aspartame and leukemia. The researchers have concluded that even a low dose (20 milligrams of aspartame per kilogram of body weight) increases the development of lymphomas, leukemia, and uritogenital tumors in rats. By the way, 50 milligrams per kilo represents the current daily acceptable dose of aspartame.

Board-certified neurologists, prominent geneticists, cardiologists, biochemists, histologists and toxicologists from different corners of the world have all drawn the same conclusion: aspartame is an addictive carcinogenic neurotoxin and teratogen, and while it may be a great biochemical warfare agent, as previously classified by the Pentagon, it should certainly be kept out of our Coke. And anything else we consume, really.

2. Bisphenol A

bpa-cans

Bisphenol A (BPA) is described as a gender-bending chemical because it mimics estrogen, binding to the same receptors in a body as natural female hormones do. Bisphenol A is also used to make polycarbonate plastics and line tin cans. And yes, it’s in Coke.

Canada became the first jurisdiction in the world to declare BPA a toxic substance and the French Senate unanimously decided to suspend from January 2015 the manufacture, import and export of all food and beverage containers which include the synthetic hormone.

The World Health Organization said there was “very strong evidence” in animals that endocrine-disrupting chemicals like BPA can interfere with thyroid hormones. This dangerous interaction could cause brain damage, autism, decrease intelligence and attention deficit hyperactivity disorder. In addition, various studies have linked BPA exposure to obesity, neurological issues, breast cancer, prostate cancer, DNA methylation, reproductive system malfunctions, and birth defects.

Coca-Cola is under a lot of pressure to do something about this, after 26% of its shareholders demanded more information on how the company is addressing the risk of BPA. Thus far, they’ve rejected the call.

1. High Fructose Corn Syrup

homer-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.

Top 10 Inventors Who Made

Modern Life Possible

We all know the names of the great minds of history: Newton, Einstein, Edison, Franklin, Jobs, Gates, and even Zuckerberg. But some of the greatest societal innovations of all time–things you use or think about ever day, probably without even realizing it–happened behind the scenes, and their inventors fell into history’s ether of anonymity. Some of these unsung heroes include:

10. James Goodfellow, inventor of ATMs and the PIN system

atm-inventions

James Goodfellow is a newly knighted Englishman credited with inventing the ATM (automatic teller machine) and, more importantly, the concept of the PIN (personal identification number). It’s because of him that you can go get money outside of a bank and can have any semblance of privacy while doing so. To this day Goodfellow insists that he was “only doing (his) job” when he dreamt up the revolutionary concept. And even though it’s used by hundreds of millions of people around the world every single day, Goodfellow says his invention hasn’t earned him a single penny.

9. Sir John Harrington, inventor of the toilet

toilet-inventions

In the midst of Medieval Europe when sewage systems were a disastrous exercise in smelly futility, Sir John Harrington conceptualizing modern plumbing. He’s also the reason a toilet is called a “John”. Sir Harrington, the godson of Queen Elizabeth I, is credited with inventing the first flush toilet in 1596. Harrington’s first prototypes were obnoxiously expensive and had to be custom built into people’s homes, including that of the Queen herself.

8. Joseph Fry, inventor of the chocolate bar

chocolate-inventions

He essentially industrialized chocolate and is not only the reason that you can eat chocolate in the first place, but the reason there is so much of it: after figuring out how to grind cocoa beans with a steam engine, he invented the first ever chocolate bar to be sold to the public in 1847. His ideas conceived the first cocoa butter, a paste that could, for the first time ever, be molded into solid chocolate. Prior to his innovations, chocolate was a luxury item that could only be consumed as an expensive beverage. Without Fry, chocolate would still be a royal pain in the ass to consume in any form.

7. Dennis Ritchie, father of modern computer programming

programming-inventions

Even though billionaires like Jobs and Gates get the credit for “revolutionizing” the computer, Dennis Ritchie invented C programming and Unix, both of which are still providing the framework for every modern computer system today. Ritchie is frequently overlooked as one of the contributors to the computer but his innovations are still used every day, and have surely paved the way for new updates and ideas to come.

6. Hunter Shelden, inventor of the seatbelt

seatbelt-inventions

He was a neurosurgeon who, in 1959, revolutionized cars with the modern seat belt. Shelden frequently saw horrific car accident injuries–most often severe head and brain trauma–come through his hospital and judged that the current seat belts were actually contributing to the problem, so with some help from Congress he made a new one. The seat belts he designed turned out to be an ingenious step towards automobile safety and the standard mandated model in all automobiles today.

5. Pellegrino Turri, inventor of the typewriter

typewriter-inventions

Typewriters were the ancestors to today’s keyboards, and they are indeed relics. The first typewriters were massive contraptions that operated slowly and frequently malfunctioned, but they were nonetheless one of the single most important innovations in history. The first typewriter was built by Italian inventor Pellegrino Turri, who designed and built the device for his blind friend.

4. Scott Falham, inventor of the emoticon

emoticons-inventions

Emoticons permeate social networking, emailing, texting, and just about any form of informal written exchange on any given day. Some love them and some hate them, but we all use them. So where did they even come from? Scott Falham, a professor at Carnegie Mellon University in Pittsburgh, PA, sent the first emoticon–a sideways smiley face complete with that outdated dash for a nose–in 1982. While he had initially expected his new idea to take hold with some success, he could not foresee its enormous explosion, and he absolutely hates those yellow icons.

3. Adolph Rickenbacher, inventor of the electric guitar

electric-guitar-inventions

The electric guitar revolutionized music as we know it today. Ask anyone who invented the electric guitar, and they’ll tell you in a second: Les Paul. The truth, though, is that Les Paul simply revamped the electric guitar. The original electric guitar was called the “frying pan” (for its banjo-esque resemblance to a frying pan) and was invented in America by Adolph Rickenbacher, a German immigrant. He had so little faith in the longevity of his creation that he only produced them for a few years before selling his entire company. He died at the age of 90 in 1976, doomed to spend eternity in the shadow of Les Paul.

2. Willis Haviland Carrier, inventor of air conditioning

air-conditioner-inventions

Anyone who’s ever experienced a sweaty office on a hot summer day knows how fantastic the air conditioner is, but they probably don’t know just where it came from. In 1901, Willis H. Carrier patented the first ever air conditioning machine. Prior to his invention, air conditioning methods were just elaborate ventilation systems that didn’t actually produce cold air. Carrier’s new machine could take in pressurized air and pass it over a cooling system before blowing it to wherever it needed to go. The company that he founded, Carrier Engineering Corporation, has long since survived him and is still the largest producer of climate control technology in the world.

1. William Upjohn, inventor of dissolvable pills

dissolvable-pills-inventions

Before the turn of the 20th century, patients who needed medicine either took it as a liquid or a hard pill. However, the liquids often tasted terrible and the pills usually didn’t even dissolve in patients’ stomachs. William Upjohn, a University of Michigan student in 1875, began experimenting with new pill formulas that would make for a more efficient treatment option. He succeeded, and is the single reason pills are such a convenient

The fire tetrahedron

Fires start when a flammable and/or a combustible material, in combination with a sufficient quantity of an oxidizer such as oxygen gas or another oxygen-rich compound (though non-oxygen oxidizers exist that can replace oxygen), is exposed to a source of heat or ambienttemperature above the flash point for the fuel/oxidizer mix, and is able to sustain a rate of rapid oxidation that produces a chain reaction. This is commonly called the fire tetrahedron. Fire cannot exist without all of these elements in place and in the right proportions. For example, a flammable liquid will start burning only if the fuel and oxygen are in the right proportions. Some fuel-oxygen mixes may require a catalyst, a substance that is not directly involved in anychemical reaction during combustion, but which enables the reactants to combust more readily.

Once ignited, a chain reaction must take place whereby fires can sustain their own heat by the further release of heat energy in the process of combustion and may propagate, provided there is a continuous supply of an oxidizer and fuel.

“I do not endorse any fire except for heating and cooking.”
