Does Diet A&W Root Beer Have Aspartame in It?

4 min read

According to the ingredient list on product labels, Diet A&W Root Beer—now known as A&W Zero Sugar—does contain the artificial sweetener aspartame. The reformulation from 'Diet' to 'Zero Sugar' was a branding change, not an ingredient overhaul, and the beverage continues to use a blend of sweeteners to achieve its classic flavor without sugar. This blend typically includes both aspartame and acesulfame potassium.

Quick Summary

A&W Zero Sugar, previously Diet A&W, is sweetened with a blend of artificial sweeteners, primarily aspartame and acesulfame potassium. The product rebranding did not change the sweetener composition. Consumers should check the product label for the full list of ingredients and be aware of the sweetener blend used.

  • Sweetener Blend: The soda also includes acesulfame potassium in its formula.

  • Branding Change: The switch from 'Diet' to 'Zero Sugar' did not change the sweetener content.

Yes, A&W Zero Sugar Contains Aspartame

For those wondering, "does diet A&W root beer have aspartame in it?", the answer is yes. The product, which was rebranded from 'Diet A&W' to 'A&W Zero Sugar,' still includes aspartame in its formulation. This is a key ingredient for achieving its zero-calorie, sugar-free profile. In addition to aspartame, the beverage also uses acesulfame potassium (Ace-K). This combination of sweeteners is designed to mimic the taste and sweetness of regular root beer, providing a familiar and satisfying flavor without the calories and sugar.

The Shift from 'Diet' to 'Zero Sugar'

The name change from 'Diet A&W Root Beer' to 'A&W Zero Sugar' was a marketing move to appeal to a broader consumer base. Many people find the term 'diet' unappealing or associate it with an older generation of soft drinks. The 'zero sugar' label is seen as more modern and health-conscious, attracting those who simply want to reduce their sugar intake. Despite the name change, A&W has confirmed that the formula remains largely the same, preserving the same great taste. This means that anyone seeking to avoid aspartame must also avoid the current 'Zero Sugar' version.

Why Do Companies Blend Artificial Sweeteners?

It's common practice for beverage manufacturers to use a blend of artificial sweeteners instead of just one. There are several strategic reasons for this:

  • Improved Flavor Profile: Different sweeteners have unique flavor characteristics and aftertastes. Aspartame, for example, is known for a clean, sweet taste, while acesulfame potassium can sometimes have a slightly bitter aftertaste. By combining them, manufacturers can balance out these traits, creating a more well-rounded and appealing flavor.
  • Synergistic Sweetness: Combining sweeteners can result in a sweetness effect that is greater than the sum of its parts. This allows for less of each sweetener to be used, which can help mitigate any potential aftertaste issues and reduce costs.
  • Stability: Some artificial sweeteners hold up better under different conditions than others. Acesulfame potassium is more stable under high temperatures, which can be useful in processing. Aspartame, however, can lose some of its sweetness over time, so a blend can help maintain a consistent flavor throughout the product's shelf life.

Potential Considerations for Aspartame Consumers

For most people, aspartame consumption within the acceptable daily intake (ADI) levels set by health organizations like the FDA and WHO is not considered a health risk. However, there are a few important considerations:

  • Phenylketonuria (PKU): Individuals with the genetic disorder phenylketonuria must avoid aspartame. Their bodies cannot properly metabolize phenylalanine, one of the amino acids found in aspartame. For this reason, products containing aspartame must include a warning on their label. This is a critical health consideration for those with PKU.
  • Taste Sensitivity: Some individuals are particularly sensitive to the aftertaste of artificial sweeteners. While blending sweeteners helps, some people may still notice a difference compared to regular sugar.
  • Health Concerns: As with any artificial sweetener, ongoing research and discussions exist regarding potential long-term health effects. Organizations like the World Health Organization have placed aspartame in a category of "possibly carcinogenic," though they maintain that the ADI remains safe based on current evidence. Consumers should be aware of these discussions and make informed choices based on their own dietary preferences and health goals.

What to Look for on the Label

When you are at the store, the easiest way to confirm the sweeteners used in A&W's sugar-free options is to check the ingredient label. The label for A&W Zero Sugar will explicitly list "Aspartame" and "Acesulfame Potassium". This is the most reliable source of information, as product formulations can sometimes vary by region or change over time. Being a vigilant label-reader ensures you know exactly what is in your drink. [EWG's Food Scores | A&w Zero Sugar Root Beer, 1.4.4]

Conclusion

To answer the question definitively, yes, Diet A&W root beer (now A&W Zero Sugar) does contain aspartame, along with acesulfame potassium, as its primary artificial sweeteners. The company's rebranding from "Diet" to "Zero Sugar" was a marketing strategy that did not alter the fundamental sweetening ingredients. For individuals with phenylketonuria or those with sensitivities to aspartame, alternative root beer brands that use different sweeteners, such as Zevia's stevia-based products, are available. Always make a habit of checking the ingredient label to be sure of what you are consuming.
