The controversy surrounding Mountain Dew's safety has long revolved around several key ingredients, with brominated vegetable oil (BVO) being one of the most prominent. A food additive used as an emulsifier, BVO was previously included to prevent citrus flavorings from separating. However, citing consumer demand and health concerns, PepsiCo confirmed its removal in 2020, following similar removals from other major soft drink brands. The FDA has also taken steps toward a formal ban on BVO, with a proposed rule announced in December 2023. This has led many to believe the drink is now entirely safe, but a closer look at the remaining ingredients tells a more complex story. The primary health risks associated with Mountain Dew have shifted away from the specific controversy around BVO and toward more common culprits found in most sodas: excessive sugar, high acidity, and other artificial additives.
The Lingering Health Concerns
While the elimination of BVO is a positive step, it doesn't solve all the health concerns associated with Mountain Dew. The drink remains an ultra-processed food, primarily composed of water, high-fructose corn syrup, and various artificial additives. Regular consumption is linked to a host of health issues that are well-documented in scientific literature.
High Sugar Content
The most significant health risk comes from the sheer amount of sugar. A standard 12-ounce can of Mountain Dew contains a staggering 46 grams of sugar, mostly from high-fructose corn syrup. This is equivalent to over 11 teaspoons of sugar, a substantial portion of the recommended daily intake for added sugars. Excessive sugar intake is directly linked to an increased risk of obesity, type 2 diabetes, and cardiovascular disease.
High Acidity and Dental Health
Mountain Dew is notoriously acidic, with a pH of around 3.2, even more acidic than Coca-Cola. This high acidity, combined with the copious sugar, creates a perfect storm for dental erosion. The acid softens tooth enamel, while the sugar feeds bacteria that produce more enamel-destroying acid. The dental industry even has a term, "Mountain Dew Mouth," to describe the severe decay associated with excessive consumption of the soda.
Artificial Colors and Additives
The vibrant yellow-green color of Mountain Dew comes from artificial dyes like Yellow 5 (tartrazine). While the FDA considers these dyes safe for consumption, they have been a source of controversy and concern for years, with some studies suggesting links to hyperactivity in children. Other preservatives like sodium benzoate, while generally safe, have also been flagged for potential risks in certain conditions.
Mountain Dew vs. Healthier Alternatives: A Comparison
| Feature | Mountain Dew (Regular) | Mountain Dew Zero Sugar | Water (The Ultimate Alternative) |
|---|---|---|---|
| Sweetener | High-Fructose Corn Syrup | Aspartame, Acesulfame Potassium | None |
| Sugar Content (12 oz) | 46 grams | 0 grams | 0 grams |
| Calories (12 oz) | 170 | 0 | 0 |
| Acidity (pH) | Extremely High (~3.2) | Extremely High (~3.2) | Neutral (7.0) |
| Additives | Artificial Colors (Yellow 5), Preservatives | Artificial Sweeteners, Preservatives | None |
| Dental Health Impact | Highly damaging due to sugar and acid | Damaging due to high acidity | Neutral, beneficial |
| Long-Term Health Risks | Obesity, Type 2 Diabetes, Tooth Decay | Potential long-term effects of artificial sweeteners, Tooth Erosion | None |
Making a Healthier Choice
The most direct way to avoid the risks associated with Mountain Dew is to choose healthier alternatives. These include:
- Plain water: The best option for hydration and overall health.
- Flavored sparkling water: Offers fizz without the sugar, acid, or artificial dyes.
- Iced tea with no added sugar: A naturally flavorful, low-calorie option.
- Moderation is key: For those who still want to enjoy the flavor, limiting consumption to a rare treat is the best approach. Avoid sipping it throughout the day, as this prolongs the acid's damage to your teeth.
The Verdict: Is Mountain Dew Safe Now?
While the removal of the controversial BVO ingredient is a notable change, it does not make Mountain Dew a safe beverage for regular consumption. The primary health threats posed by the drink—its immense sugar content and high acidity—remain unchanged. For those concerned with their overall health, dental hygiene, and the risks associated with excessive sugar, alternatives should be prioritized. Even in its reformulated state, Mountain Dew is still best enjoyed in moderation, if at all.
Conclusion
In summary, the question of whether is Mountain Dew safe now has a nuanced answer. The removal of brominated vegetable oil has addressed one specific concern, but the core health risks associated with its high sugar and acid levels persist. Ultimately, the safety of any soda depends heavily on the frequency and quantity of consumption. For optimal health, the best practice is to choose water or other low-sugar, low-acid beverages as daily hydration choices.
