What You'll Learn
Dr Pepper contains phosphoric acid
Indeed, phosphoric acid is not considered a strong acid, but an 85% solution is corrosive. Dr Pepper also contains condensed polyphosphoric acids, which are formed due to the high percentage of phosphoric acid. Phosphoric acid is added to sodas to give them their distinctive sharp taste. However, excessive consumption of phosphoric acid through sodas can have negative health effects.
Phosphorus is the second most abundant mineral in the human body and is essential for various functions, including filtering waste and repairing tissues. While phosphorus naturally occurs in many foods, it is also added to processed foods and drinks, meaning that people often consume more phosphorus than their body needs. Phosphorus additives make up between 10% to 50% of phosphorus intake in a typical Western diet, and a can of cola can contain 50 to 60 mg of phosphoric acid.
Excessive phosphorus intake can lead to negative health effects, such as an increased risk of osteoporosis and heart disease. This is because too much phosphorus can decrease calcium levels in the body, leading to bone loss. It can also impair the body's ability to absorb other essential minerals like iron, zinc, and magnesium. Therefore, while Dr Pepper does contain phosphoric acid, it should be consumed in moderation as part of a balanced diet to avoid any potential negative health consequences.

Phosphoric acid is an additive
Phosphoric acid is added to sodas to increase their acid content. In fact, sodas typically have more acid content than vinegar or lemon juice due to the inclusion of phosphoric acid. Phosphoric acid is also added to flavoured waters, with some containing up to 85 mg of phosphorus per bottle.
The recommended daily amount (RDA) of phosphorus for normal bodily function in adults is 700 mg. Most people get enough phosphorus in their diet, as it is found naturally in many foods, especially those high in protein such as dairy, meat, beans, eggs, chicken, and fish. Bread and other bakery goods also contain phosphorus. Therefore, the additional intake of phosphoric acid from processed foods and drinks like soda is likely more than the body needs.
Some experts are concerned about the amount of added phosphorus in the typical Western diet, which can make up between 10% to 50% of phosphorus intake. Excessive phosphorus intake has been linked to negative health effects, including an increased risk of osteoporosis and heart disease. People with kidney disease may need to monitor their phosphorus intake, as their kidneys may be unable to remove excess phosphorus from the body.

Excess phosphorus can cause health issues
Dr Pepper is a carbonated drink with a unique blend of 23 fruit flavours. The drink contains phosphoric acid, which is added to contribute to its tart flavour and increase its acidity. While Pepsi claims that phosphoric acid is harmless and even healthy, most experts believe this opinion is biased. This is because several studies have indicated that phosphoric acid in large amounts can cause health issues.
Individuals with diabetes, high blood pressure, heart disease, a family history of kidney disease, or abnormal kidney structure are at an increased risk of developing hyperphosphatemia. Additionally, Black, Hispanic, Asian, Native American, and First Nations individuals are also at a higher risk for this condition.
The normal amount of phosphorus in the blood for individuals with healthy kidneys is between 2.5 to 4.5 mg/dL. If levels exceed 4.5 mg/dL, it indicates hyperphosphatemia. To diagnose this condition, a healthcare provider will review an individual's medical history, conduct a physical examination, and consider factors such as symptoms, diet, and medications.
Treatment for hyperphosphatemia focuses on lowering phosphorus levels in the body. This can be achieved through medications such as phosphate binders and phosphate blockers, as well as dietary modifications to limit the intake of phosphate and calcium. Working with a dietitian who specializes in kidney health can help individuals make informed choices about their food and drink options to maintain healthy phosphorus levels.

Phosphoric acid is corrosive
Phosphoric acid is an ingredient in many sodas, including Diet Dr Pepper. It is what gives sodas their distinctive tart flavour. However, phosphoric acid is corrosive. This means that it can cause deterioration in metals and alloys.
Phosphoric acid corrosion typically occurs in low-velocity areas and low points where water mixes with the catalyst. Examples of equipment that may be affected include piping manifolds, bypass lines, and storage tanks. The corrosion process can compromise the structural integrity of metals, potentially leading to equipment failure.
Factors that influence phosphoric acid corrosion include acid concentration, water content, temperature, and contaminants. Corrosion rates increase with higher temperatures and the presence of contaminants like chlorides, fluorides, and other halide salts.
To prevent or mitigate phosphoric acid corrosion, several measures can be implemented. These include ensuring proper equipment design, performing material compatibility tests, selecting corrosion-resistant materials, and applying protective coatings. Additionally, using corrosion inhibitors and controlling temperature and acid concentration can help minimize corrosive effects.
While phosphoric acid is corrosive, it is worth noting that it is less corrosive than other acids such as sulfuric and hydrochloric acids.

Phosphoric acid contributes to soda's tartness
Phosphoric acid is an ingredient in many sodas, including Dr Pepper, where it contributes to the drink's tartness. This ingredient is what gives sodas their unique, tangy flavour, which is created by the combination of tartness, sweetness, and carbonation. Phosphoric acid increases the acid content of the drink, making it more acidic than vinegar or lemon juice.
The phosphoric acid in Dr Pepper is not in the form of a strong acid, but it is still corrosive. In fact, an 85% solution of phosphoric acid is corrosive enough to be labelled as H3PO4, despite not being in the ortho form. This high percentage of phosphoric acid means that some of the orthophosphoric acid is condensed into polyphosphoric acids.
Phosphoric acid is added to sodas to make them more tart, but it also serves another purpose. Phosphorus, the element that makes up phosphoric acid, is the second most plentiful mineral in the human body. It is necessary for many bodily functions, such as filtering waste and repairing tissues. However, it is important to note that too much phosphorus can be harmful. While it is naturally found in many foods, it is also added to processed foods and drinks, meaning that people may be consuming more than their body needs.
Some studies have linked high phosphorus consumption to an increased risk of bone fractures, as it can decrease calcium levels and impair the body's ability to absorb other essential minerals. However, the safe upper limit of phosphorus intake is 4,000 mg per day, and a can of cola typically contains only 50 to 60 mg of phosphoric acid. Therefore, drinking soda in moderation is not likely to cause negative health effects, but excessive consumption could be harmful.

Frequently asked questions
Yes, phosphoric acid is listed as an ingredient in Diet Dr Pepper.
Phosphoric acid is an additive used in many sodas to create a tart flavor. It is also found naturally in many foods. Phosphoric acid is not a strong acid, but an 85% solution is corrosive.
While your body does need phosphorus to function, too much can cause negative health effects. Phosphorus works with calcium to form and maintain healthy teeth and bones, but too much phosphorus can decrease the amount of calcium in your body and lead to bone loss. Excess phosphorus can also impair your body's ability to use other minerals, such as iron, zinc, and magnesium.
Phosphorus is found in many foods that are high in protein, such as dairy, meat, beans, eggs, chicken, and fish. Bread and other bakery goods also contain phosphorus. Since phosphorus is already common in many natural food sources, the additional phosphoric acid from processed food and drinks may be more than your body needs.
