Is zero sugar Mountain Dew healthier?

4 min read

According to a 2025 UNC Health Appalachian article, zero-sugar sodas are not ideal for long-term health and weight loss, challenging the common assumption that diet versions are automatically better. This raises the important question: Is zero sugar Mountain Dew healthier? We explore the nutritional realities behind the marketing claims to provide a clear answer.

Quick Summary

Zero sugar Mountain Dew, while free of added sugar and calories, contains artificial sweeteners and lacks nutritional value. Research links frequent consumption of artificially sweetened drinks to various potential health issues, including altered gut health and increased cravings for sweets. For optimal health, water or other unsweetened beverages are superior choices.

Key Points

  • Artificial Sweeteners: Zero sugar relies on artificial sweeteners like aspartame and sucralose, which lack nutritional value and may have potential long-term health effects.

  • Not a Health Drink: Despite having zero calories and sugar, it is not a healthy beverage and should not replace water or nutritious drinks.

  • Potential Health Risks: Some studies associate artificial sweeteners with a higher risk of metabolic syndrome, diabetes, and other health issues, although research is mixed.

  • Dental Concerns: The high acidity in both regular and zero sugar sodas can erode tooth enamel over time, increasing the risk of cavities.

  • Higher Caffeine: Zero Sugar Mountain Dew contains more caffeine than the regular version, which can be a concern for those sensitive to stimulants.

  • Moderation is Key: For better overall health, it's best to reduce reliance on all sodas, diet or regular, and prioritize water.

The Core Difference: Sugar vs. Sweeteners

The most significant distinction between regular Mountain Dew and its Zero Sugar counterpart lies in their sweeteners. Regular Mountain Dew is packed with high-fructose corn syrup, a caloric sweetener that contributes to its high sugar and calorie count. In contrast, Mountain Dew Zero Sugar uses a combination of artificial sweeteners, primarily aspartame, sucralose, and acesulfame potassium, to achieve a similar sweet taste without the calories. While this substitution effectively removes the added sugar, it introduces a new set of considerations regarding health and nutrition.

Artificial Sweeteners and Your Body

Artificial sweeteners are non-nutritive, meaning they provide little to no calories. However, this does not mean they are inert. Some studies suggest that the intense sweetness of these additives can affect the body in unintended ways:

  • Triggering Cravings: Some researchers suggest artificial sweeteners can interfere with the brain's food reward pathway. This can potentially increase cravings and dependence on sweet foods, making it harder to reduce overall sugar intake.
  • Gut Microbiome Disruption: The artificial sweeteners sucralose and saccharin have been shown to alter the balance of beneficial bacteria in the gut. A healthy gut microbiome is crucial for digestion, immunity, and overall health.
  • Metabolic Effects: Despite being calorie-free, the consumption of artificial sweeteners has been associated with metabolic issues. One study found links between diet soda and an increased risk of metabolic syndrome and type 2 diabetes.

A Nutritional and Ingredient Breakdown

To make an informed choice, it's essential to look beyond the 'zero sugar' label and examine the full ingredients and nutritional profile. Here is a comparison of regular and Zero Sugar Mountain Dew based on information gathered from product listings and health sources:

Feature Regular Mountain Dew (12 fl oz can) Zero Sugar Mountain Dew (12 fl oz can)
Calories ~170 0
Total Sugar ~46g (Added Sugar) 0g (Added Sugar)
Sweeteners High Fructose Corn Syrup Aspartame, Sucralose, Acesulfame Potassium
Caffeine ~54 mg ~68 mg (20% more)
Acidity High (Citric Acid) High (Citric Acid)
Nutritional Value None None

The Health Effects of Zero Sugar

While eliminating the copious amounts of sugar from a regular soda is a positive step for controlling caloric intake and managing blood sugar, Mountain Dew Zero Sugar is not a health beverage. Its ingredients and characteristics come with their own set of potential drawbacks:

  • Increased Caffeine: Mountain Dew Zero Sugar actually contains 20% more caffeine than the regular version. For individuals sensitive to stimulants, this could lead to issues such as increased heart rate, blood pressure spikes, and anxiety.
  • Dental Erosion: Both regular and diet sodas are highly acidic due to ingredients like citric acid. This acidity can wear away tooth enamel over time, increasing the risk of dental cavities and sensitivity, even without the presence of sugar.
  • Lack of Nutrients: Neither version of the soda offers any nutritional benefits. They are essentially beverages filled with flavorings, colorings, and acids, displacing more nutritious drink options like water, milk, or unsweetened tea from a person's diet.

Healthier Alternatives and Conclusion

Ultimately, the question of whether is zero sugar Mountain Dew healthier? is not a simple yes or no. It is healthier in the sense that it eliminates the massive amount of sugar and calories found in the original, which is a significant factor for those managing diabetes or weight. However, it is not healthy and introduces its own set of potential long-term risks associated with artificial sweeteners and high acidity. As many health experts recommend, the best choice for hydration and overall health is to reduce reliance on all sodas, both regular and diet, and choose healthier alternatives.

Some healthier beverage options to consider include:

  • Water: Plain or flavored with fruit slices (lemon, cucumber, berries). It's the best option for hydration with no calories, sugar, or artificial ingredients.
  • Seltzer or Sparkling Water: Provides the bubbly sensation of soda without the unwanted additives. You can add a splash of 100% fruit juice for a hint of flavor.
  • Herbal Tea: Naturally flavored and provides warmth or coolness, depending on preparation.
  • Kombucha: A fermented tea that offers probiotics, though some brands may contain sugar.

While an occasional Zero Sugar Mountain Dew is less harmful than a regular one, viewing it as a truly healthy choice is a mistake. The ongoing debate about the long-term effects of artificial sweeteners is still evolving, and moderation is the most prudent approach.

The Verdict: Less Bad, Not Good

In conclusion, Zero Sugar Mountain Dew is a better choice for someone who is already a regular high-sugar soda drinker and wants to cut down on calories. It helps manage blood sugar levels and weight more effectively than the sugar-laden version. However, the product is still a highly-processed, nutrient-empty beverage containing artificial sweeteners and high acidity. It does not provide any nutritional benefits and can be associated with other health issues, including dental erosion and potential metabolic concerns. The healthiest long-term strategy is to decrease dependence on all types of soda and transition to water and other naturally healthy beverages.

Healthier Alternatives to Zero Sugar Soda

Making the switch from diet or regular soda doesn't have to be difficult. You can transition to a healthier habit by incorporating more flavorful, but natural, beverages into your routine. Starting by adding sliced fruit to your water or exploring herbal tea blends can be a great first step towards long-lasting positive change.

Artificial sweeteners are low-glycemic, meaning they do not directly spike blood sugar like regular sugar does. However, some studies suggest links between artificial sweeteners and altered glycemic responses or insulin resistance.

Yes. The high acidity from ingredients like citric acid in zero sugar soda can erode tooth enamel, just like regular soda, increasing the risk of dental problems.
