Doctors Warn: Soda Can Seriously Damage Your Entire Body

Certain Coca-Cola bottles claim that the drink contains no artificial flavors and chemical preservatives. This seems to be the company’s newest strategy to get the more health-conscious costumers back on board.

The only problem is that the labeling is somewhat misleading. Coke contains the notorious phosphoric acid, which is essentially both an artificial flavor and a preservative, and has been linked to many health problems.

Read on to find out what happens to your body when you consume Coca-Cola and how it can destroy your bones.

What Happens when you Drink a Can of Soda

Here is what happens within an hour of drinking a can of soda:

Within 20 minutes, you get a sugar high. Your blood sugar spikes, resulting in a quick release of the hormone insulin. The liver tries to compensate by turning excessive sugar into fat and storing it around the body.

Within 40 minutes, all the caffeine is absorbed and your body responds to this substance: the pupils dilate, blood pressure rises, and the liver dumps even more sugar into the bloodstream.

Around 45 minutes after you have had your drink, the body increases dopamine production, which gives the person an imminent sensation of pleasure – this is similar to the way the body responds to heroin.

After 60 minutes, you develop a sugar crash. You can experience fatigue, change in mood, lethargy, mental fogginess.

A can of coke contains about 10 teaspoons of sugar, which amounts to 100% of your recommended daily intake.

The extreme sweetness is masked by phosphoric acid, which prevents the body from developing an immediate reaction to the glucose overload. Here is how phosphoric acid can destroy your bones.

How a Can of Coke Can Destroy your Bones

Coke contains phosphoric acid

Coca-Cola contains Phosphoric which is also known as E338, orthophosphoric acid, and phosphoric(V) acid.

It is a mass-produced chemical, available cheaply and in large quantities. It can be used to remove rust, while the food-grade phosphoric acid is a very acidifying agent. It makes the drink more acid than vinegar or lemon juice.

Some studies have linked phosphoric acid to osteoporosis, chronic kidney disease and kidney stones.

One such study was published in The American Journal of Clinical Nutrition in 2006. The main conclusion of the study was that drinking cola is associated with low bone mineral density (BMD) in women. Women who were drinking Coke daily, had 3.7% lower BMD at the femoral neck compared to those who didn’t consume the drink. The link was not found with other carbonated soft drinks.

There was however a study that claimed just the opposite, and linked low phosphor intake to lower bone density. This study was funded by Coca-Cola, so the findings are not unbiased, and the validity of the study has been questioned.


Soda Can Cause Depression

According to the American Academy of Neurology (AAN), people who drank more than four cans or cups per day of soda were 30 percent more likely to develop depression than those who drank no soda.5

Soda Can Cause Kidney Damage

The National Kidney Foundation advises strongly against the consumption of soda. Kidney function declined over two decades in women who drank several diet sodas a day, according to researchers from the prestigious Nurses’ Health Study. In fact, compared with women who did not drink diet soda, soda-drinking women had a 30% greater reduction in kidney function in 20 years. More than 3,000 women have participated in the study for 20 years or more; now the women’s median age is 67 years.6

Soda Damages Your Lungs

According to the journal Respirology, drinking soda might raise the risk for respiratory diseases like asthma and chronic obstructive pulmonary disease (COPD). 7

Drinking Diet Soda Damages Your Brain

Excessive consumption of sugar is one of the most dangerous brain damaging habits but did you know that even sugar free diet soda can potentially damage your brain? Aspartame, a common artificial sweetener in diet sodas can harm your brain. According to a study published in the journal Drug and Chemical Toxicology, long-term consumption of aspartame leads an imbalance in the antioxidant/pro-oxidant status in the brain.7

Soda Damages Your Teeth

According to a study, excessive intake of soft drinks could cause complex dental consequences including dental erosion and tooth decay.8

Soda Damages Your Heart

Consumption of fizzy beverages harms the heart. According to a Harvard-based study, drinking soda increases the risks of coronary heart disease. Adverse changes in lipids, inflammatory factors, and leptin were also noted. Those participants of the study who drank the most sugary drinks, had 20% higher chances of developing a heart attack (see my post about 10 signs of heart attack you should not ignore).


Soda drinks affect almost every part of your body and the short-term and long-term consequences can be quite drastic. By avoiding fizzy drinks, you will promote the health of your brain, lungs, heart and teeth.

Coca-Cola is Under Fire for its Deceptive Labeling

As I mentioned at the beginning of this post, certain Coca-Cola bottles claim that the drink contains no artificial flavors and chemical preservatives. Coca-Cola is under fire for its deceptive labeling, and several class action lawsuits have been filed across the US.

The company officials say that phosphoric acid is not on the Food and Drug Administration’s (FDA) list of artificial flavors, so they are not obliged to name it as one. But this claim was quickly discredited, as the FDA’s list is not meant to be exhaustive.

The FDA defines artificial flavors as ingredients included specifically to add flavor and which are not derived from natural sources like fruit and vegetable juice, plant materials, or dairy products, among other things.


Coke doesn’t hide the fact that phosphoric acid is used in its signature drink, and includes it in the list of ingredients. It adds tartness to Coke (that’s why the abundance of sugar has to be used to mask and balance the acidity), and prevents spoilage, so it’s clearly a flavoring and a chemical preservative.

Where else you can Find Phosphate Compounds

Meat and dairy products also contain phosphate compounds, which is probably why they can cause inflammation in the body.

According to the Center for Science in the Public Interest (CSPI), most phosphates in the American diet don’t come from soft drinks, but from animal products. Taking that into consideration, Coke might be more harmful due to its high sugar content, and less for the phosphoric acid it contains.

Food and beverage labeling is becoming a big battlefield, and there is a lot of scope for fraud and product misrepresentation. Common ingredients found in processed foods can be harmful for our health (and you can read about them in my article about the top 10 worst ingredients in food).

It is clear that Coke is not a natural drink. People buy it for other reasons, and being healthy is not one of them.

    Phosphoric acid is produced and used within your body during metabolic processes around ADP/ATP energy metabolism. Phosphorus and phosphates are a essential component to life.
    Phosphoric acid is an acid correct but, it is more acidic than vinegar and other acids. However, you have forgotten about the stomach whose acid content is far stronger than phosphoric acid. Phosphoric acid is used in soda to keep carbon dioxide in solution ie a preservative of “fizziness”. Not all preservatives are “bad”. Phosphoric acid exists naturally in nature as part of the life cycle of phosphorus again an essential component of life like water, carbon, nitrogen, etc..

    From an acid perspective, drinking soda would supplement the age related decline of stomach acid. However, to much would affect pH in the GI tract and affect nutrient absorption and digestion processes. Carbon dioxide expands the stomach providing more room for food and may result in over consumption of food. Carbon dioxide can be absorbed in the stomach lining directly into the blood and form carbonic acid. This will have little effect on the blood pH and chemistry due to the buffering capacity of your blood. Again, over consumption may lead to affecting the pH of blood. Once this capacity has been stretched then problems can arise from the change of blood chemistry due to the lowering of pH.

    Sugar has its own problems. Too much can cause a hole list of problems. Blood levels affect the insulin response which leads to irregular blood levels which affects many things due to improper energy levels. Diabetes is one of the most common and also brain function.

    So what else in soda is causing the problem? Good question – maybe the caramel additives, other natural and artifical flavourings? Regardless, correct information should be given so that the public is not misinformed about the risks of drinking soda. Should we stop drinking soda? Maybe but, perhaps a reduction would be appropriate nonetheless but that depends on your current health status. If you carbohydrate daily intake is reduced then is drinking soda moderately a problem? I do not know just wanted to clarify some finer points that are often overlooked, mistated and quite frankly wrong.

    If you put 20 penny nails in a container with coca cola in it, the nails will disintegrate very rapidly. Do you think we need that in our bodies?

    A 10 ounce coca cola has 10 teaspoons of sugar in it. Do you think it is good to drink something that has that much sugar in it?

    Personally, I have never drank carbonated drinks and I hope I never get the urge to do that. I don’t need the sugar and I certainly don’t want to drink something that can dissolve 20 penny nails.

  3. Joseph says:

    Pepsi & Coke are known killers ! I carried the chemicals from Ireland to other EU countries in the backs of trailers.

    Often a container would be leaking the chemical would eat through a 1/4 plate steel chassis of the trailer.

    These chemicals did cause health problems just to breath in the vapours on a hot day caused problems.

    They should be banned, they are killing children / people.

    thank you for the healthy info…

  5. ernst west says:

    I like this article very much. its very educating. its true that many will oppose it but the truth must be told irrespective peoples action or reaction.

    • Mas'ud Ibn Mahamud says:

      Tnx 4 your advice u doing a great job by letting us know the effect of coke in our bodies & what it does to our bones there may be so many critics especially dealing with a big company like coca cola, no matter the circumstances the truth must be said

  6. Laurine says:

    Thank you so much for letting us know these effeccts of these substances I also have been drinking too much of coke I will pass on the message to others so that they can be saved from these health hazardous substances

  7. Tina Ameh says:

    Thanks so much for the information, i like taking chilled coke when am tired but i will stop it as from today. What about other soft drinks like fanta, mirinda, bitterlemon and so many?

    • Jenny Hills says:

      Soft drinks in general are full of artificial ingredients and should be avoided as much as possible. Drink instead herbal teas or flavored water or green smoothies.

      • Sammie McDonald says:

        I do not understand all of this. I am sure that there are plenty of chemicals and preservatives in many, many different foods and drinks today and depending on the source of the information received would govern how serious the effects reported. I personally have drank approximately one gallon of coke per day for about forty years and I have experienced none of the symptoms you propose. I am now 66 years old and am still healthy. I propose that you should reinvestigate your findings for I find them completely unvalidated. If you wish to reply to this email I would gladly answer.

        • Jenny Hills says:

          Hi Sammie, the findings are based on the resources at the end of the article. I cannot argue with your personal results. I believe it’s a personal choice of every person to decide what he/she consumes. If it works well for you, then by all means continue to enjoy it and drink it. It’s your life and your choice and I respect it. I’m not going to try and convince anyone to make any changes in his/her life. Do what you think is right for you and I wish you to continue and enjoy good health.
