Aspartame is a low-calorie artificial sweetener found in thousands of food and beverage products around the world. It was discovered in 1965 and has since become one of the most widely used sugar substitutes. Most commonly, it is found in 'diet' or 'zero sugar' soft drinks as a way to achieve a sweet taste without the calories associated with sugar. However, for a variety of reasons, including health concerns and dietary restrictions like phenylketonuria (PKU), many people prefer to avoid it. This guide will help you navigate the beverage aisle to determine which soft drinks contain aspartame.
Coca-Cola Products with Aspartame
Many of Coca-Cola's low-sugar and zero-calorie offerings are sweetened with aspartame, sometimes in combination with other sweeteners like acesulfame potassium (Ace-K). To confirm, always check the ingredients list, which is typically located next to the Nutrition Facts panel.
- Diet Coke: The original sugar-free cola, Diet Coke is primarily sweetened with aspartame.
- Coca-Cola Zero Sugar: This version, created to taste more like the original Coca-Cola, uses a blend of aspartame and Ace-K.
- Sprite Zero Sugar: This lemon-lime soda uses a combination of aspartame and Ace-K.
- Fanta Zero: The zero-sugar versions of Fanta flavors, such as Orange, often contain aspartame.
- Other brands: Other Coca-Cola products with aspartame include Fresca, Diet Barq's, and Pibb Zero.
PepsiCo Products with Aspartame
PepsiCo, another industry leader, also uses aspartame in many of its reduced-calorie and sugar-free products. This includes popular diet and zero-sugar varieties that are widely available in stores and restaurants.
- Diet Pepsi: Traditionally sweetened with aspartame, though some formulations may vary.
- Pepsi Zero Sugar: Similar to Coca-Cola Zero Sugar, this drink uses a combination of aspartame and Ace-K.
- Diet Mountain Dew: This variant of the popular citrus-flavored soda is also sweetened with aspartame.
- Diet Mug Root Beer: The diet version of this classic root beer uses aspartame.
- Diet Dr Pepper: While often produced by Keurig Dr Pepper, distribution can overlap. Diet Dr Pepper is commonly sweetened with aspartame.
Other Common Brands Containing Aspartame
Beyond the two major beverage companies, many other brands and generic store-brand diet sodas use aspartame. It is a cost-effective and powerful sweetener, making it a popular choice for manufacturers.
- 7UP Zero Sugar: The zero-sugar formulation of this lemon-lime soda contains aspartame.
- Red Bull Sugar-Free: This energy drink utilizes aspartame as one of its artificial sweeteners.
- Some drink mixes: Products like Crystal Light often contain aspartame for a low-calorie, sweetened beverage option.
Understanding Ingredient Labels for Aspartame
Knowing what to look for on a product label is crucial for avoiding aspartame. It is most frequently found in products explicitly labeled as 'diet,' 'sugar-free,' or 'zero sugar'.
- Ingredient List: Aspartame will be listed directly in the ingredients. You can find this on the back of the can or bottle, often near the Nutrition Facts panel.
- Common Name: While the name 'aspartame' is always used, some consumers may recognize its brand names, which include NutraSweet® and Equal®.
- Phenylketonurics (PKU) Warning: Due to the phenylalanine content in aspartame, products containing it must carry a warning for individuals with PKU. This serves as a clear and unambiguous signal that the product is sweetened with aspartame.
