Diet Pepsi is a diet carbonated cola soft drink produced by PepsiCo and introduced in 1964 as a sugar-free variant of Pepsi. The drink has undergone several formulation changes over the years, including a shift from the artificial sweetener saccharin to aspartame in 1983. Aspartame has been a controversial ingredient, with critics expressing concerns about potential health risks, including its possible link to the development of brain tumors in humans. Despite this, regulatory agencies in various countries, including the United States, have deemed aspartame safe for consumption. In recent years, there have been conflicting reports about the presence of aspartame in Diet Pepsi, with some sources indicating that it was removed from the ingredient list for a brief period. As of 2023, it appears that aspartame is once again listed as an ingredient in Diet Pepsi, particularly in the US market.

What You'll Learn
Aspartame is an artificial sweetener
Aspartame was first introduced as a tabletop sweetener and food additive in 1974 and was approved for use in chewing gum, cold breakfast cereals, and dry bases for beverages and dairy products. In 1983, it became the main sweetener in Diet Pepsi, replacing saccharin due to health concerns. In 2015, Pepsi briefly removed aspartame from its formula, but due to flopping sales, it was reintroduced in 2016 as "Diet Pepsi Classic Sweetener Blend". Today, aspartame is one of the top three ingredients in Diet Pepsi, alongside water and caramel colour.
Aspartame has been the subject of controversy, particularly regarding its potential health risks. In 1996, a report by 60 Minutes alleged that aspartame might be linked to the development of brain tumours in humans. However, regulatory agencies, including the U.S. Food and Drug Administration (FDA), have deemed aspartame safe for human consumption at current levels. The FDA considers aspartame to be safe under approved conditions and continues to monitor the latest scientific research on sweeteners.
In July 2023, the World Health Organization's (WHO) International Agency for Research on Cancer (IARC) classified aspartame as possibly carcinogenic to humans (Group 2B) due to limited evidence for cancer in humans and animals. However, the FDA and other regulatory bodies disagree with this conclusion, stating that there are shortcomings in the studies and that aspartame is safe within the current acceptable daily intake (ADI) levels. The JECFA committee, for example, reaffirmed that it is safe for a person to consume up to 0-40 mg/kg body weight of aspartame per day.
Aspartame is not heat stable and loses its sweetness when heated, so it is typically not used in baked goods. It is approved for use as a sweetener in many countries, and consumers may choose to use it as a sugar substitute to reduce their overall sugar intake or for its low-calorie content.

It has been deemed a possible carcinogen
Aspartame, an artificial sweetener, has been the subject of controversy. In 1996, a report by 60 Minutes alleged that aspartame might be linked to the development of brain tumours in humans. This prompted PepsiCo to remove the ingredient from its diet soda in 2015. However, sales flopped, and aspartame was reintroduced in Diet Pepsi a year later.
The World Health Organization's International Agency for Research on Cancer (IARC) has deemed aspartame a "possible carcinogen". This determination is based on studies indicating a positive association between consumption of artificially sweetened beverages (containing aspartame) and liver cancer in humans. The IARC's decision was influenced by animal studies, which provided "limited evidence of carcinogenicity".
It is important to note that the IARC's conclusion is not unanimous. A minority of IARC experts found the animal evidence to be "sufficient" to establish that aspartame causes cancer in animals, warranting a higher classification. However, regulatory agencies in various countries, including the U.S. Food and Drug Administration, have stated that aspartame is safe for consumption at current levels.
Despite the controversy, aspartame remains a popular ingredient in many diet and sugar-free drinks, including Diet Pepsi. PepsiCo has expressed its intention to continue using aspartame, citing consumer demand and the importance of maintaining the product's taste.

It was removed from Diet Pepsi in 2015
Aspartame is an artificial sweetener commonly used in many diet and sugar-free drinks. It has been the subject of controversy, with critics expressing concerns about its potential health risks. In response to these concerns, PepsiCo decided to remove aspartame from Diet Pepsi in 2015.
The removal of aspartame from Diet Pepsi was short-lived, however. Due to declining sales and backlash from brand loyalists, PepsiCo reintroduced aspartame to the drink in 2016, just a year after its removal. The new formulation, known as the "Diet Pepsi Classic Sweetener Blend", was sold alongside the aspartame-free version.
The decision to bring back aspartame was likely influenced by the strong consumer preference for the familiar sweetener. Despite the health concerns, aspartame has been deemed safe for human consumption by regulatory agencies in several countries, including the United States.
In 2018, PepsiCo announced plans to revert to using aspartame as the primary sweetener in Diet Pepsi, and the new formulation was released market-wide on February 25, 2018. This change solidified the return of aspartame to Diet Pepsi, marking a shift away from the brief period between 2015 and 2018 when the drink was aspartame-free.

It was brought back in 2016 due to poor sales
Aspartame is an artificial sweetener commonly used in many diet and sugar-free drinks. It is one of the ingredients that give Diet Pepsi its distinct taste. In 2015, PepsiCo decided to remove aspartame from its diet soda formula due to consumer concerns about possible health risks associated with the ingredient. This decision was made in response to feedback from diet cola drinkers in the US, who expressed their preference for an aspartame-free alternative.
However, following this change, Pepsi saw a sharp decline in sales. Diet soda sales dropped by more than 5% in 2015, with Diet Pepsi sales falling by 5.8% while Diet Coke sales decreased by 5.6%. Overall, Pepsi's sales declined by 6.8% for its entire range of diet sodas. The company attributed this drop to the removal of aspartame, as consumer feedback indicated that the new aspartame-free sodas lacked the familiar taste of the original recipe.
In response to the poor sales, Pepsi reintroduced aspartame to its Diet Pepsi formula in 2016. The company brought back the original sweetener under the name "Diet Pepsi Classic Sweetener Blend", which was sold alongside the aspartame-free version in the US market. This move aimed to cater to consumers who were more concerned with taste than the inclusion of aspartame.
The decision to bring back aspartame highlights the importance of taste preferences in the highly competitive soft drink market. While some consumers may have health concerns about specific ingredients, taste remains a critical factor influencing purchasing decisions. By offering a variety of options, including the classic taste, Pepsi aimed to regain its market share and appeal to a broader range of consumers.
Despite the controversy surrounding aspartame, regulatory agencies in various countries, including the US, have deemed it safe for human consumption. While health agencies have issued warnings about potential risks, other experts argue that these concerns are overblown, and aspartame is safe for consumption at current levels. The debate around aspartame continues, but for now, it remains a key ingredient in Diet Pepsi, contributing to its distinctive flavour and consumer appeal.

It is deemed safe for consumption by regulatory bodies
Aspartame is an artificial sweetener used in many diet and sugar-free products, including Diet Pepsi. It is deemed safe for consumption by regulatory bodies, although there have been concerns and debates about its safety.
Aspartame has been a subject of controversy, with critics expressing concerns about potential health risks. In 1996, a report on the "60 Minutes" show alleged a possible link between aspartame and brain tumors in humans. This prompted PepsiCo to remove aspartame from its diet soda, although it was later reintroduced due to flopping sales.
Despite these concerns, aspartame has been deemed safe for human consumption by regulatory agencies in various countries. The U.S. Food and Drug Administration (FDA), Health Canada, and the European Food Safety Authority (EFSA) have all evaluated aspartame and consider it safe at current permitted use levels. The FDA, in particular, has reviewed more than 100 studies designed to identify possible toxic effects and continues to monitor the latest scientific literature.
The World Health Organization (WHO), along with the International Agency for Research on Cancer (IARC) and the Joint Expert Committee on Food Additives (JECFA), has also assessed the health impacts of aspartame. IARC classified aspartame as possibly carcinogenic to humans (Group 2B) due to limited evidence, while JECFA reaffirmed the acceptable daily intake of 40 mg/kg body weight. However, a second WHO committee noted that a person would need to consume a significant amount of diet drinks to exceed this safe threshold.
Overall, while there have been concerns and debates about the safety of aspartame, it is important to note that regulatory bodies have deemed it safe for consumption at current permitted levels. These assessments are based on extensive scientific studies and evaluations, and regulatory agencies continue to monitor new evidence and research in this area.
