The Sweetener in Question: High-Fructose Corn Syrup
High-fructose corn syrup (HFCS) is a calorie-dense sugar substitute derived from cornstarch through an industrial process. It is a pervasive ingredient in many processed foods and beverages in the United States, including the classic Mountain Dew.
Why the concern over HFCS?
Medical and nutritional research has linked high consumption of added sugars, including HFCS, to various health issues. ScienceDirect provides an overview of how high fructose consumption may lead to insulin resistance, impaired glucose tolerance, and fatty liver disease. For individuals seeking to manage their weight or blood sugar, avoiding beverages containing HFCS is a common strategy.
The Artificial Sweeteners in Mountain Dew Zero
Mountain Dew Zero Sugar is specifically formulated to be a zero-calorie option, and it achieves this by replacing corn syrup with a blend of artificial sweeteners. According to the product's ingredient list, it contains:
- Aspartame: A low-calorie artificial sweetener that is broken down by the body into its component parts. It is generally considered safe but contains phenylalanine, which is a concern for individuals with the rare genetic disorder phenylketonuria (PKU).
- Acesulfame Potassium: A calorie-free artificial sweetener that is often used in combination with other sweeteners to create a more sugar-like taste.
- Sucralose: Also known as Splenda, sucralose is a zero-calorie artificial sweetener that is 600 times sweeter than sugar. It is derived from sucrose but chemically modified so the body does not recognize it as a carbohydrate.
Mountain Dew Zero vs. Original: A Comparison
Understanding the differences between Mountain Dew Zero Sugar and its original counterpart is crucial for making an informed dietary choice. The table below highlights the key distinctions based on their nutritional facts and ingredient lists.
| Feature | Mountain Dew Zero Sugar | Original Mountain Dew |
|---|---|---|
| Sweetener | Aspartame, Acesulfame Potassium, Sucralose | High-fructose corn syrup (in the U.S.) |
| **Calories (per 12 oz)*** | 0 | ~170 (approximate) |
| **Sugar (per 12 oz)*** | 0g | 46g (approximate) |
| **Added Sugars (per 12 oz)*** | 0g | 46g (approximate) |
| Caffeine Content (per 12 oz) | 68mg | 54mg |
| Notable Ingredients | Artificial sweeteners, caffeine, preservatives | HFCS, caffeine, concentrated orange juice, preservatives |
Note: Nutritional information may vary slightly depending on the container size and regional formulation. The values listed are based on typical 12 oz (355 ml) can sizes.
The Ongoing Debate: Artificial Sweeteners and Health
Switching from HFCS to artificial sweeteners reduces calorie and sugar intake, which can be beneficial for managing weight and blood sugar. However, the health effects of artificial sweeteners are not without debate. Research has produced mixed results on their impact on overall health, gut health, and appetite.
Potential issues with artificial sweeteners
- Gut Microbiota: Some animal studies and human trials have shown that certain artificial sweeteners, including sucralose, may alter the balance of gut bacteria. However, a 2023 review of randomized controlled studies found no significant change in gut microbiota after ingesting artificial sweeteners.
- Appetite and Cravings: The theory that artificial sweeteners confuse the body by providing sweetness without calories, potentially leading to increased cravings for sugary foods, has been explored. While some studies have suggested this effect, other research refutes it, showing that replacing sugary beverages with diet versions can lead to reduced calorie intake.
- Metabolic Effects: Some observational studies have linked diet soda consumption to a higher risk of conditions like metabolic syndrome, but controlled studies often show no negative effect on blood sugar or insulin levels. The data is still inconclusive, and more research is needed to understand the long-term impact on different populations.
Navigating Your Drink Choices
For those looking to reduce sugar intake, replacing sugary drinks with zero-calorie alternatives can be a step in the right direction. However, it's essential to understand that 'zero sugar' doesn't automatically mean 'healthy.'
Here are some tips for making healthier beverage choices:
- Prioritize Water: The best beverage for hydration remains plain water. Add flavor with natural fruits like lemon, lime, or berries.
- Read Labels Carefully: Don't rely solely on front-of-package claims. Examine the ingredients list to see exactly what is in your drink, including specific types of sweeteners.
- Moderate Consumption: Whether you choose regular or zero-sugar soda, moderation is key. Over-reliance on artificially sweetened drinks may not be the optimal path for reducing sugar cravings or improving metabolic health.
- Consider Alternatives: Explore other zero-sugar options like unsweetened tea, sparkling water, or naturally flavored seltzers for a crisp, refreshing experience without artificial additives.

Conclusion
To answer the central question, Mountain Dew Zero Sugar does not contain high-fructose corn syrup, distinguishing it from the regular version of the soda. Instead, it is sweetened with a blend of artificial sweeteners like Aspartame, Acesulfame Potassium, and Sucralose to provide a zero-calorie beverage. This makes it a popular alternative for those looking to cut sugar from their diet. However, it's important for consumers to be aware of the ongoing scientific discussions regarding the long-term effects of artificial sweeteners. While they can be a useful tool for reducing caloric and sugar intake, a balanced nutritional approach still emphasizes whole foods and plain water as the foundation of a healthy diet.
