Diet Pepsi is a diet carbonated cola soft drink produced by PepsiCo, introduced in 1964 as a sugar-free variant of Pepsi. Since its launch, Diet Pepsi has undergone several formulation changes, including a shift from the artificial sweetener saccharin to aspartame in 1983. In 2015, Pepsi altered the sweetener again to sucralose, prompting a negative response from consumers and leading to the reintroduction of the aspartame formulation in 2016. The presence of iodine in Diet Pepsi has been a topic of discussion, especially for those following a low-iodine diet due to thyroid cancer or other health reasons. While there is limited information on the specific ingredients of Diet Pepsi, some sources suggest that certain ingredients, such as red dye or ginseng root extract, may be of concern for those on a low-iodine diet.

What You'll Learn
Diet Pepsi ingredients
Introduced in 1964, Diet Pepsi is a diet carbonated cola soft drink produced by PepsiCo. It was first test-marketed in 1963 under the name Patio Diet Cola and was rebranded as Diet Pepsi the following year. It was the first diet cola to be distributed on a national scale in the United States.
The initial formulation of Diet Pepsi was sweetened with the artificial sweetener saccharin. However, in the 1970s, concerns emerged about the use of saccharin, leading to a shift to an alternative sweetener, aspartame, in 1983. Aspartame has also been a subject of controversy, with critics expressing concerns about potential health risks associated with its consumption. Nonetheless, regulatory agencies in various countries, including the United States, have deemed aspartame safe for human consumption at current levels.
In 2015, Pepsi altered the formula once more, which was met with distaste by some consumers. As a result, the company reintroduced the aspartame formulation as "Diet Pepsi Classic Sweetener Blend" in the US in 2016, and it was sold alongside the new formula.
The ingredients in Diet Pepsi vary slightly depending on the market and have changed over time. In Australia, the caffeine-free version, known as Pepsi Light Caffeine Free, lists the following ingredients:
- Carbonated Water
- Caramel Color
- Phosphoric Acid
- Aspartame
- Sodium Benzoate
- Acesulfame Potassium
- Natural Flavour
- Citric Acid
Other variations of Diet Pepsi have been introduced over the years, including additional flavours such as wild cherry, vanilla, lemon, and lime. While the specific ingredients may vary, the primary sweetener in Diet Pepsi products has typically been aspartame, a low-calorie sweetener.
It is worth noting that while Diet Pepsi is marketed as a sugar-free beverage, the presence of artificial sweeteners and other ingredients may be a concern for some consumers, particularly those with specific dietary restrictions or health considerations.

Iodine in Diet Pepsi
It is unclear whether Diet Pepsi contains iodine. While the soft drink's ingredients are listed as carbonated water, caramel colour, phosphoric acid, aspartame, sodium benzoate, acesulfame potassium, natural flavour, and citric acid, there is no mention of iodine. However, some sources indicate that certain ingredients in Diet Pepsi, such as red dye and ginseng root extract, may contain iodine or be unsuitable for a low-iodine diet.
Diet Pepsi is a sugar-free variant of Pepsi that was introduced in 1964. Over the years, PepsiCo has made several changes to the formulation, including switching from saccharin to aspartame as the artificial sweetener in 1983. In 2015, the company faced backlash over another formula change and reintroduced the aspartame formulation as "Diet Pepsi Classic Sweetener Blend." Additional variations of Diet Pepsi have been introduced, including different flavours and a caffeine-free version.
The presence of iodine in Diet Pepsi is a concern for individuals on a low-iodine diet, often prescribed for those with thyroid cancer or related conditions. While some sources suggest that Diet Pepsi is generally permitted on a low-iodine diet, others recommend avoiding it due to the potential presence of iodine in certain ingredients. It is always advisable to consult with a healthcare professional or refer to reputable sources for specific dietary guidelines and restrictions.
It is worth noting that the ingredients in Diet Pepsi and other processed foods can vary by region and over time. Therefore, it is essential to read the ingredient labels carefully and stay informed about any changes or updates to the product formulation. Additionally, it is recommended to prioritise whole, unprocessed foods and limit the consumption of soft drinks, as they are often associated with added sugars, artificial sweeteners, and other potentially harmful ingredients.

Diet Pepsi and thyroid cancer
While there is no explicit mention of iodine in the ingredients of Diet Pepsi, some people with thyroid cancer have expressed concerns about the drink's compatibility with a low-iodine diet. This is because, in 2012, Pepsi Zero was found to contain ginseng root extract, which is listed as having iodine. However, it is unclear whether this variety of Diet Pepsi is still sold or if it contains the same ingredients today.
The relationship between diet and thyroid cancer has been the subject of several studies, which have produced inconsistent results. A hospital-based case-control study in Sicily, Italy, found a positive association between the consumption of iodized salt and an increased risk of thyroid cancer. The study also reported an increased risk associated with the consumption of Coca-Cola, but it is unclear whether this risk extends to other colas, such as Diet Pepsi.
It is worth noting that the same study found an inverse association between the disease risk and the consumption of vegetables, milk and dairy products, and seafood. Additionally, it confirmed the protective effect of a daily water intake of 1-2 litres.
While there is no definitive evidence that Diet Pepsi directly contributes to thyroid cancer, it is generally recommended that those on a low-iodine diet limit or avoid the consumption of diet soda and opt for water instead. This is especially important in the period leading up to RAI treatment, where a strict low-iodine diet is typically advised.

History of Diet Pepsi
Diet Pepsi was first test-marketed in 1963 under the name Patio Diet Cola and was rebranded as Diet Pepsi the following year. It was the first national diet soft drink in America and the first low-calorie soda produced by a major American company.
In the 1960s and 1970s, its competition consisted of Tab by The Coca-Cola Company and Diet Rite Cola by RC Cola. During this time, Diet Pepsi was packaged in glass bottles and was also available in cans.
In 1982, The Coca-Cola Company introduced Diet Coke, which became the primary competing product to Diet Pepsi. In 1983, Diet Pepsi switched from saccharin to NutraSweet (aspartame) as a sweetener. In 1986, Diet Pepsi began using a segmented logo, similar to the AT&T logo at the time.
In 1994, Diet Pepsi became the first national beverage brand to print expiration dates directly on aluminum cans, a practice dubbed "freshness dating." In 2008 and 2009, PepsiCo twice overhauled Diet Pepsi's visual branding, transforming its traditional logo into a new minimalist, lower-case stylized design.
In December 2012, Diet Pepsi changed its sweetener to sucralose, which was met with negative feedback on social media in 2015. In response, Pepsi revived its aspartame formulation as "Diet Pepsi Classic Sweetener Blend" in 2016, which was sold alongside the new formula.
In 2018, PepsiCo released a new formulation, reverting Diet Pepsi's sweetener from sucralose back to aspartame. Additional variations of Diet Pepsi have been introduced over the years, including flavours such as wild cherry, vanilla, lemon, and lime. A caffeine-free version is also produced, known as Pepsi Light Caffeine Free in Australia.
PepsiCo also produces other low-calorie colas, including Pepsi Max and Pepsi Zero Sugar, the latter of which was originally known as Diet Pepsi Max until 2009.
