Diet Pepsi and Pepsi Zero Sugar are both sugar-free cola options produced by PepsiCo, designed as alternatives to regular Pepsi. While they share the goal of providing a low- or no-calorie cola experience, they differ in ingredients, taste, and marketing. This article explores the nutritional facts, ingredients, taste profiles, and historical context of Diet Pepsi and Pepsi Zero Sugar to help consumers make informed choices.
Historical Context and Development
Diet Pepsi, initially test-marketed as Patio Diet Cola in 1963, was rebranded in 1964, becoming the first diet cola distributed nationally in the United States. Its success was attributed to changing dietary habits among Baby Boomers. Over the years, Diet Pepsi has expanded globally and introduced various flavored variations, such as Wild Cherry and Caffeine-Free Diet Pepsi. PepsiCo later introduced Pepsi Max (primarily in Europe) in 1993 and Pepsi One (in the United States) in 1998, further diversifying its sugar-free cola offerings.
Ingredients and Nutritional Facts
Both Diet Pepsi and Pepsi Zero Sugar share several key ingredients, including carbonated water, caramel color, phosphoric acid, potassium benzoate, caffeine, and citric acid. However, the sweeteners used differentiate the two products. Diet Pepsi uses aspartame as its primary artificial sweetener, while Pepsi Zero Sugar uses a blend of aspartame and acesulfame potassium.
A 12-ounce serving of both Diet Pepsi and Pepsi Zero Sugar contains:

A closer look
The order in which ingredients are listed also varies slightly between the two drinks. For instance, aspartame is the third ingredient in Diet Pepsi and the fourth in Pepsi Zero Sugar. Diet Pepsi also includes acesulfame potassium, which is not listed as an ingredient in Pepsi Zero Sugar. Though Diet Pepsi is represented worldwide as a low- or no-calorie beverage, the ingredients comprising its makeup vary in some cases by the country of origin.

Taste Comparison
Taste is a significant differentiating factor between Diet Pepsi and Pepsi Zero Sugar. Diet Pepsi is often described as having a crisp, lighter finish with a slightly dry cola flavor. Some find it cleaner and less like regular Pepsi. In contrast, Pepsi Zero Sugar is formulated to taste more like regular Pepsi, with a richer, more intense sweetness due to the combination of aspartame and acesulfame potassium. Some consumers find that Pepsi Zero Sugar has a more full-bodied flavor.
Marketing and Branding
Diet Pepsi and Pepsi Zero Sugar are marketed differently, targeting distinct consumer preferences. Diet Pepsi, with its silver can, has traditionally been marketed towards a broader audience seeking a lighter, low-calorie option. Pepsi Zero Sugar, packaged in a black can, is often marketed towards those who want a sugar-free cola that closely mimics the taste of regular Pepsi.
Advertising Over the Years
Initially advertised alongside Pepsi, Diet Pepsi began to be promoted independently in the late 1960s. The first television advertisement to feature Diet Pepsi as a standalone product was "Girlwatchers," which placed focus on the cosmetic aspects of the beverage. Since its inception, musicians, professional athletes, actors, and actresses have been featured prominently in the promotion of Diet Pepsi.
Health Considerations
Diet sodas, including Diet Pepsi and Pepsi Zero Sugar, have faced scrutiny regarding their potential health effects. These beverages typically contain artificial sweeteners, such as aspartame, which have been subject to safety evaluations by regulatory bodies like the Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA).
Potential health issues
Some studies suggest potential links between diet soda consumption and issues such as tooth enamel erosion due to the presence of citric acid, malic acid, and phosphoric acid. However, it's essential to consider that these acids are also found in many other foods and beverages.

Expert Opinion
According to Healthline, "Diet soda is essentially a mixture of carbonated water, artificial or natural sweetener, colors, flavors, and other food additives,". The Ohio State University Wexner Medical Center reports that "Regular soda is generally a mixture of carbonated water and sweeteners, like high fructose corn syrup or sucrose; phosphoric acid, if it's a dark cola; 'natural flavors;' and caffeine".
Consumer Preferences and Perceptions
Consumer preferences for Diet Pepsi and Pepsi Zero Sugar vary widely. Some consumers prefer Diet Pepsi for its familiar taste and lighter profile, while others prefer Pepsi Zero Sugar for its closer resemblance to regular Pepsi. Taste memory plays a significant role in these preferences, with many consumers remaining loyal to the version they grew up with.
The new taste
Many people have become accustomed to the way Diet Pepsi tastes and don't want it to change, even if there's a superior low/no calorie Pepsi on the market. It's similar to New Coke vs Classic Coke.
International Availability
The availability of Diet Pepsi and Pepsi Zero Sugar (or similar products) varies by country. For example, in the UK, Pepsi Max is more common than Diet Pepsi, while Coca-Cola, Diet Coke, and Coke Zero are widely available. In some regions, Diet Pepsi may be known as Pepsi Light, with slight variations in ingredients.
The "Diet" Label and Misconceptions
The use of the term "diet" in the names of these sodas can be misleading. While Diet Pepsi and Pepsi Zero Sugar are lower in calories and sugar than regular Pepsi, they are not necessarily "healthy" beverages. They provide minimal nutritional value and may have potential health implications associated with artificial sweeteners and other additives.

FDA Regulations
Ultimately, the Food and Drug Administration (FDA) allows companies like Pepsi and the Coca-Cola company to use the term "diet" or "light" for these drinks and don't consider the labeling to be misleading.
