Soft drinks are notoriously acidic, and their acidity can have a detrimental effect on the enamel of our teeth. Dr Pepper is a popular soda with a distinctive flavour derived from a blend of 23 fruit flavours. The drink's acidity comes from the acids it contains, including phosphoric acid, citric acid, and lactic acid. The pH level of Dr Pepper is 2.89, which is less acidic than Coke or Pepsi but still highly acidic and potentially harmful to teeth. This article will explore the different acids present in Diet Dr Pepper and their potential health implications.

What You'll Learn
Phosphoric acid
The use of phosphoric acid in sodas has been linked to negative health effects. Phosphoric acid is a food additive, and the amount of phosphorus absorbed from food additives is much higher than that from natural sources. This is a concern for individuals with chronic kidney disease, who cannot adequately remove phosphorus from their bodies and are at a higher risk of developing hyperphosphatemia. This condition can lead to elevated parathyroid hormone secretion, progressive deterioration of kidney function, renal bone disease, vascular calcification, increased risk of cardiovascular accidents, and higher mortality rates.
Furthermore, phosphoric acid in sodas contributes to their high acidity, which can be harmful to tooth enamel. Enamel is a protective coating on teeth that prevents decay and gives teeth their unique colour. When enamel dissolves due to exposure to acidic substances, it cannot be regenerated. As a result, sodas with high levels of phosphoric acid, such as Diet Dr Pepper, can contribute to tooth decay and discolouration.

Lactic acid
In the context of Dr Pepper, lactic acid is added as an ingredient to enhance the drink's flavour profile. Its presence gives the beverage a subtle tanginess or sourness, contributing to the overall taste experience.
The inclusion of lactic acid in Dr Pepper has been a subject of interest and speculation among consumers. While it is not listed on the ingredient labels in some regions, it has been confirmed as an ingredient by the company. For example, in Canada, lactic acid is sometimes listed on the cans, whereas in other regions, it may be included under the category of "artificial flavours" or "food acids".
The presence of lactic acid in Dr Pepper is an intriguing aspect of its formulation, contributing to the drink's unique and beloved flavour that has captivated consumers for years.

Citric acid
The pH level of a substance indicates its acidity or alkalinity, with lower pH levels indicating higher acidity. Dr Pepper has a pH level of 2.89, which is lower than that of Coke and Pepsi but higher than cherry Coke. This makes it a highly acidic drink, comparable to other colas and clear diet sodas.
Acidic drinks can have negative effects on the body, particularly the teeth. The enamel on teeth, which is a protective coating that gives teeth their colour, can be damaged by highly acidic substances. As enamel does not regenerate, it is important to be mindful of the acidic content of drinks like Diet Dr Pepper to prevent potential harm to dental health.
While the presence of citric acid contributes to the overall acidity of Diet Dr Pepper, it is not the only factor. Other ingredients, such as phosphoric acid and artificial sweeteners, also play a role in the drink's acidity and potential health impacts. Additionally, the combination of ingredients in Diet Dr Pepper may create a unique flavour profile that enhances the taste of the drink, making it a popular choice despite its high acidity.
Overall, while Diet Dr Pepper does contain citric acid, it is important to consider the interplay of all its ingredients and their effects on the body to fully understand the potential benefits and drawbacks of consuming this beverage.

Benzoic acid
Sodium benzoate is listed as an ingredient in Diet Dr Pepper. It is also present in other diet soft drinks, including Diet Mountain Dew, as well as the diet versions of Barq's Root Beer and Sunkist Orange. It is worth noting that sodium benzoate can have side effects when consumed in high quantities and is considered an additive of moderate concern in food.
In addition to its use as a preservative, sodium benzoate also has anti-fungal properties, which help to protect food from spoilage caused by fungi. This, in turn, helps to prevent food from becoming contaminated with harmful substances that could make consumers sick. This property makes sodium benzoate particularly useful in the preservation of acidic foods, such as pickles, sauces, jams, and fruit juices.
While sodium benzoate has its benefits as a preservative and flavour enhancer, there are some potential drawbacks. According to the FDA, when combined with other foods containing vitamin C, sodium benzoate can become toxic. This is because the combination of these substances can lead to the formation of benzene, which is a known carcinogen. However, it is important to note that the levels of benzene found in these combinations have been below the dangerous limit, according to the same organisation.
Overall, benzoic acid, in its sodium benzoate form, plays a significant role in the food industry, especially in the production of soft drinks like Diet Dr Pepper. While it has its advantages in terms of preservation and flavour enhancement, it is important to be aware of the potential side effects and health concerns associated with its consumption.

Aspartame (contains phenylalanine)
Aspartame is an artificial sweetener that has been in use in the United States since the early 1980s. It is much sweeter than sugar, so less of it is required to provide the same level of sweetness. Aspartame is commonly used as a tabletop sweetener, as a sweetener in prepared foods and beverages, and in recipes that don't require a lot of heating (as heat breaks down aspartame). It can also be found as a flavouring in some medications, chewing gums, and toothpastes.
Aspartame has been the subject of health concerns for many years, with some studies suggesting it may be linked to an increased risk of certain cancers. However, the results of epidemiologic studies investigating the potential link between aspartame and cancer have been inconsistent. The American Cancer Society does not determine if a substance is carcinogenic, but they note that the International Agency for Research on Cancer (IARC), the cancer research agency of the World Health Organization (WHO), classifies aspartame as "possibly carcinogenic to humans" (Group 2B). This classification is based on limited evidence suggesting a potential link to liver cancer in humans and lab animals.
Despite the concerns, aspartame has been evaluated by various scientific advisory bodies, including the Scientific Committee for Food of the European Community and the Joint Expert Committee on Food Additives (JECFA) of the United Nations Food and Agriculture Organization and World Health Organization. These organisations have reviewed the available safety studies and concluded that aspartame is safe for consumption when used according to the provisions of food regulations and as part of a balanced diet.
It is important to note that aspartame contains phenylalanine, an amino acid. Excessive intake of phenylalanine can be hazardous to individuals with phenylketonuria (PKU), a rare genetic disorder in which the body cannot break down this amino acid. Therefore, products containing aspartame must carry a warning label stating "PHENYLKETONURICS: CONTAINS PHENYLALANINE." This label can be used to identify products with aspartame for those who wish to avoid it.
