Diet Pepsi is a diet carbonated cola soft drink produced by PepsiCo and introduced in 1964. It was the first diet cola to be distributed on a national scale in the United States. The drink is marketed as a low- or no-calorie beverage, and its ingredients vary depending on the country of origin. Aspartame, an artificial sweetener, has been a common ingredient in Diet Pepsi. However, due to concerns over its safety and possible links to cancer, PepsiCo has made changes to the formulation, removing and then reinstating aspartame at different times. The presence of aspartame in Diet Pepsi has been a topic of discussion and debate among consumers and in the media.

What You'll Learn
Aspartame is an artificial sweetener
Aspartame has been the subject of controversy, with some alleging that it may be linked to health risks, including the development of brain tumours and liver cancer in humans. In 2015, PepsiCo removed aspartame from Diet Pepsi in response to these concerns. However, sales flopped, and the company brought back aspartame in 2016, marketing the drink as "Diet Pepsi Classic Sweetener Blend".
The World Health Organization's International Agency for Research on Cancer (IARC) has deemed aspartame a "'possible carcinogen'", based on studies indicating a positive association between consumption of artificially sweetened beverages and liver cancer. However, the U.S. Food and Drug Administration has stated that it disagrees with these findings, maintaining its stance that aspartame is safe for consumption. Regulatory agencies in other countries, including the U.S., have also deemed aspartame safe for human consumption.
Despite the controversy, aspartame remains a popular choice for beverage companies due to its ability to provide a crisp, refreshing zero-calorie cola taste that consumers expect from diet drinks.

PepsiCo removed aspartame in 2015, but sales flopped
Aspartame is an artificial sweetener used in many diet and sugar-free drinks. It is about 200 times sweeter than sugar. In 2015, PepsiCo removed aspartame from Diet Pepsi in the United States in response to customer concerns about possible health risks. Aspartame has been a controversial ingredient, with critics expressing concerns about its consumption. However, regulatory agencies in various countries, including the United States, have deemed it safe for human consumption.
Following the removal of aspartame, PepsiCo replaced it with a blend of sucralose and acesulfame potassium in its diet offerings. The company hoped to revive falling cola sales as consumers were increasingly concerned about sugar intake and shifting away from diet sodas and artificial sweeteners. However, sales of the new aspartame-free Diet Pepsi flopped.
To address the sales decline, PepsiCo reintroduced aspartame to Diet Pepsi in 2016. The new formulation, called "Diet Pepsi Classic Sweetener Blend," was sold alongside the aspartame-free version. This move was well-received by consumers, and PepsiCo later announced plans to revert to using aspartame as the primary sweetener in Diet Pepsi.
The controversy surrounding aspartame has persisted, with some health agencies warning that it may be a carcinogen. However, other entities, such as the U.S. Food and Drug Administration, have disputed these claims, stating that aspartame is safe for consumption. The debate continues as consumers seek clarity on the safety of artificial sweeteners like aspartame.

Aspartame is deemed safe by regulatory agencies
Aspartame is an artificial sweetener commonly used in many diet and sugar-free products, including Diet Pepsi. While it has been the subject of controversy due to concerns about potential health risks, it is deemed safe for human consumption by regulatory agencies in several countries, including the United States.
In the United States, artificial sweeteners like aspartame are regulated by the Food and Drug Administration (FDA). The FDA first issued a regulation for aspartame in 1974 for specific uses and has since approved its use as a general-purpose sweetener. The FDA has reviewed more than 100 studies on the safety of aspartame and continues to monitor the latest scientific evidence. Based on this evidence, the FDA has concluded that aspartame is safe for the general population when used under approved conditions. The FDA has established an acceptable daily intake (ADI) for aspartame, which is considered protective of public health.
Other regulatory agencies have also evaluated the safety of aspartame. Health Canada and the European Food Safety Authority (EFSA) have assessed aspartame and consider it safe at current permitted use levels. The EFSA completed a risk assessment on aspartame in 2013 and stated that it and its breakdown products are safe for human consumption.
The World Health Organization (WHO), through its International Agency for Research on Cancer (IARC) and the Joint Expert Committee on Food Additives (JECFA), has also conducted assessments of aspartame. IARC classified aspartame as ""possibly carcinogenic to humans" based on limited evidence, while JECFA reaffirmed the acceptable daily intake of 0-40 mg/kg body weight, concluding that aspartame is safe for human consumption within this limit. The FDA and a second WHO committee have disagreed with IARC's findings, stating that aspartame is safe and that a person would need to consume a large number of cans of diet drinks per day to exceed the safe threshold.
While the safety of aspartame has been a subject of debate, regulatory agencies have deemed it safe for human consumption when used under approved conditions. These agencies continue to monitor and assess the latest scientific evidence to ensure the safety of the general population.

Aspartame is deemed a 'possible carcinogen' by WHO
Aspartame is an artificial sweetener used in many diet and sugar-free products, including Diet Pepsi. In 2023, the World Health Organization (WHO) deemed aspartame a "possible carcinogen". This classification was based on a review of "limited evidence" that aspartame may cause cancer in humans, specifically liver cancer. The acceptable daily intake of aspartame remains unchanged at a maximum of 40 milligrams per kilogram of body weight per day.
The WHO's announcement was met with pushback from the U.S. Food and Drug Administration (FDA), which stated that it disagreed with the WHO's findings and maintained its stance that aspartame is safe for human consumption. The FDA questioned the evidence supporting the WHO's conclusion and pointed to its own evidence of aspartame's safety. The FDA was supported by the Joint FAO/WHO Expert Committee on Food Additives (JECFA), which concluded that "the evidence of an association between aspartame consumption and cancer in humans is not convincing".
The controversy surrounding aspartame is not new. Aspartame has been the subject of debate since the 1970s when concerns emerged about its predecessor, saccharin, prompting a shift to aspartame as an alternative sweetener. In 1996, a report on the popular news show 60 Minutes alleged that aspartame might be linked to the development of brain tumors in humans. Despite these concerns, regulatory agencies in various countries, including the U.S., have deemed aspartame safe for human consumption.
While the WHO's announcement has sparked further discussion and research into the potential health risks of aspartame, it is important to note that the evidence is not conclusive. The WHO's classification of aspartame as a "possible carcinogen" is based on limited evidence, and more long-term research is needed to fully understand the potential risks. In the meantime, the WHO recommends moderation in the consumption of aspartame and other non-sugar sweeteners, especially for those who consume it as a way to avoid sugar and control weight.

Diet Pepsi is a low- or no-calorie beverage
The initial formulation of Diet Pepsi was sweetened with the artificial sweetener saccharin. However, concerns over saccharin emerged in the 1970s, prompting a shift to an alternative sweetener, aspartame, in 1983. Aspartame has been a subject of controversy, with critics expressing concerns over its potential health risks. In 2015, PepsiCo removed aspartame from Diet Pepsi due to customer concerns. However, the new formula was met with distaste, and the company revived the aspartame formulation in 2016.
The ingredients of Diet Pepsi vary slightly depending on the country of origin. In the United States, the ingredients include carbonated water, caramel color, aspartame, phosphoric acid, potassium benzoate, caffeine, citric acid, natural flavor, and acesulfame potassium. In Canada, the ingredients are similar, with the addition of sodium benzoate, flavor, and dimethylpolysiloxane. In the United Kingdom, the ingredients include carbonated water, caramel color, phosphoric acid, sweeteners (aspartame and acesulfame K), acidity regulator (sodium citrate), preservative (sodium benzoate), and citric acid.
Despite the controversies surrounding aspartame, regulatory agencies in various countries, including the United States, have deemed it safe for human consumption. However, in 2023, the World Health Organization's International Agency for Research on Cancer (IARC) announced that aspartame is a "possible carcinogen," based on studies indicating a potential increased risk of cancer in humans.
