PepsiCo's Diet Pepsi, introduced in 1964, is a zero-calorie carbonated soft drink. In 2020, PepsiCo announced that it would no longer use aspartame, an artificial sweetener, in its Diet Pepsi drinks. Aspartame has been the subject of controversy, with some studies suggesting it may be linked to cancer. PepsiCo replaced aspartame with a blend of sucralose and acesulfame potassium, which is similar to Splenda. This change positioned Diet Pepsi as a unique option compared to other diet colas, particularly Diet Coke, which still uses aspartame.

Aspartame, the sugar substitute in Diet Pepsi, has been deemed a possible carcinogen by WHO
Aspartame is an artificial sweetener used in many low-calorie food and drink products, including Diet Pepsi. It is 200 times sweeter than regular sugar, so less of it needs to be used. Aspartame has been a popular sugar substitute for those with obesity and diabetes.
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). This decision was based on limited evidence from studies that found an increased risk of cancer, specifically hepatocellular carcinoma, a type of liver cancer. There was also limited evidence of carcinogenicity in experimental animals and some understanding of the mechanisms by which aspartame may cause cancer.
However, the Joint FAO/WHO Expert Committee on Food Additives (JECFA) disagreed with IARC's classification, stating that the evidence of an association between aspartame consumption and cancer in humans is not convincing. JECFA reaffirmed the acceptable daily intake (ADI) of aspartame as 0-40 mg/kg body weight, and the US Food and Drug Administration (FDA) also maintains that aspartame is safe for consumption within daily limits.
While the debate on the possible link between aspartame and cancer continues, it is important to note that as of August 2020, PepsiCo removed aspartame from Diet Pepsi, replacing it with a blend of sucralose and acesulfame potassium. This change came about due to consumer demand and concerns about the safety of aspartame.

PepsiCo replaced aspartame with a blend of sucralose and acesulfame potassium
PepsiCo's decision to replace aspartame with a blend of sucralose and acesulfame potassium in Diet Pepsi marked a significant shift in the product's formulation. This change was announced in May 2020 and slated for release later that year, offering consumers an aspartame-free option. The move came amidst concerns about the safety of aspartame, a popular artificial sweetener in diet and sugar-free drinks.
Aspartame has been a subject of controversy, with critics voicing worries about potential health risks. In 2023, studies indicated a possible link between aspartame and cancers, as well as generational anxiety. The World Health Organization's International Agency for Research on Cancer (IARC) labelled it as "possibly carcinogenic to humans." However, other regulatory bodies, such as the FDA, have refuted these claims, deeming aspartame safe for consumption within daily limits.
By replacing aspartame, PepsiCo addressed consumer concerns and differentiated Diet Pepsi from its main competitor, Diet Coke, which continued to use aspartame. The new sweetener blend, similar to Splenda, is closer to sugar in origin than aspartame. This blend provides consumers with a crisp, refreshing zero-calorie cola taste, maintaining Pepsi's signature sweetness.
The decision to switch sweeteners was not without challenges. In 2015, PepsiCo faced backlash over the new formula, prompting them to reintroduce aspartame in 2016 as "Diet Pepsi Classic Sweetener Blend." However, they eventually returned to the blend of sucralose and acesulfame potassium, reflecting their commitment to meeting consumer demands and preferences.
This change in Diet Pepsi's formulation demonstrates PepsiCo's responsiveness to market trends and their willingness to adapt their products to address health concerns and evolving tastes. The replacement of aspartame with a blend of sucralose and acesulfame potassium represents a significant step in the evolution of diet beverages, offering consumers an alternative option to aspartame-sweetened drinks.

Aspartame is 200 times sweeter than sugar, so less is needed
Aspartame is an artificial sweetener used in many diet and sugar-free drinks, including Diet Pepsi. It is 200 times sweeter than sugar, which means that only a tiny amount is needed to achieve the same level of sweetness as sugar. This makes it a popular choice for creating low-calorie beverages, as it can be used in very small quantities while still providing a significant sweetening effect.
The use of aspartame in food and beverages has been a subject of controversy due to concerns about potential health risks. In 2023, studies raised concerns about a possible link between aspartame consumption and cancer, as well as generational anxiety. These findings led the World Health Organization's International Agency for Research on Cancer (IARC) to label aspartame as "possibly carcinogenic to humans." However, other regulatory bodies, such as the FDA in the United States, have disputed these findings, stating that aspartame is safe for consumption within acceptable daily intake limits.
Despite the concerns, aspartame has several advantages that make it a preferred choice for beverage companies and consumers. Firstly, it is one of the least expensive sugar alternatives, making it a cost-effective option for manufacturers. Secondly, it mixes well in beverages and has a pleasant taste, contributing to its popularity among consumers.
In the case of Diet Pepsi, aspartame has been a significant ingredient in its formulation. Introduced in 1964, Diet Pepsi originally used the artificial sweetener saccharin. However, concerns about saccharin emerged in the 1970s, leading to a shift towards aspartame in 1983. While Diet Pepsi briefly replaced aspartame with sucralose in 2012, they reverted to using aspartame in 2018 due to consumer demand and brand identification.
While the safety of aspartame continues to be debated, regulatory bodies provide guidelines for acceptable daily intake to ensure safe consumption. It is important for consumers to be aware of these guidelines and to consider the overall variety and balance of their diet when choosing sugar-free or artificially sweetened products.

Aspartame is one of the least expensive sugar alternatives
Aspartame is a sugar substitute that is widely used in low-calorie food and drinks. It is 200 times sweeter than regular sugar, so although it does contain calories, it is used in much smaller quantities. Aspartame is one of the least expensive sugar alternatives, and it is used in a lot of zero-sugar and low-sugar foods. For example, it is used in sugar-free Jell-O, tabletop sweeteners like Nutrasweet and Equal, Trident's sugar-free gum, and Crystal Light. It has also been used in Diet Pepsi, although PepsiCo announced in 2020 that they would be replacing aspartame with a blend of sucralose and acesulfame potassium.
Aspartame has been a popular sugar alternative for people with obesity and diabetes, as it allows them to enjoy sweet-tasting food and drinks without consuming sugar. However, there have been concerns about the safety of aspartame. In 1996, a 60 Minutes report alleged that aspartame might be linked to the development of brain tumours in humans. More recently, studies have found that aspartame may cause cancer, and it has been declared a possible carcinogen by the World Health Organization's International Agency for Research on Cancer (IARC). Nevertheless, other regulatory bodies, such as the FDA, continue to find aspartame safe for consumption within acceptable daily intake (ADI) limits.
Despite the controversies surrounding aspartame, it remains a popular choice for food and beverage manufacturers due to its low cost and intense sweetness. While there are other sugar alternatives available, such as sucralose and erythritol, aspartame is one of the most economical options. It is important to note, however, that the safety of aspartame is still a subject of ongoing research and debate.

Aspartame has been scrutinised for its possible links to brain tumours
Aspartame, the artificial sweetener used in Diet Pepsi, has been the subject of controversy for its possible links to brain tumours. In 1996, a 60 Minutes report alleged that aspartame might be linked to the development of brain tumours in humans. This allegation sparked further investigations and studies to analyse the potential correlation.
One study, published in the Journal of the National Cancer Institute, examined the link between aspartame consumption and brain tumour risk in children. The study collected data on aspartame consumption from participants in Los Angeles and San Francisco, evaluating brain tumour risk in relation to a mother's consumption of aspartame during pregnancy and breastfeeding. While the results of this specific study are not provided, the mere need for such an investigation underscores the level of concern surrounding aspartame's potential health risks.
Another study, conducted by Olney et al., suggested a correlation between increased brain cancer incidence rates in the United States and the introduction of aspartame into food products in the early 1980s. This finding adds weight to the hypothesis that aspartame may contribute to brain tumour development.
The controversy surrounding aspartame intensified with studies on animals revealing concerning results. The Ramazzini Institute (RI) reported in 2006 and 2007 that aspartame caused dose-related increases in malignant tumours in multiple organs in rats and mice, even at low exposure levels. Furthermore, prenatal exposures to aspartame resulted in increased malignancies in rodent offspring at lower doses than in adults. These findings generated intense debate, with critics questioning the accuracy of RI's diagnoses.
Despite the concerns raised by these studies, regulatory bodies have offered differing conclusions. The World Health Organization 's International Agency for Research on Cancer (IARC) labelled aspartame as "possibly carcinogenic to humans". However, the Joint WHO and Food and Agriculture Organisation's Expert Committee on Food Additives (JECFA) deemed aspartame safe for consumption within daily limits. Similarly, the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have established acceptable daily intake (ADI) levels for aspartame, deeming it safe for consumption within those limits.
In light of the conflicting evidence and ongoing debates, further research and reassessment of aspartame's carcinogenic potential are warranted. While some regulatory bodies assert its safety, the weight of concern regarding potential links to brain tumours and other cancers cannot be dismissed lightly.
