The Core Problem: Excessive Sugar and Acidity
Mountain Dew's reputation for being a poor health choice is largely rooted in its nutritional profile, specifically its high sugar and acid content. A single 12-ounce can of Mountain Dew contains 46 grams of sugar, exceeding the American Heart Association's daily recommendation for added sugar intake. This excessive sugar load not only contributes to weight gain but also creates a breeding ground for harmful bacteria in the mouth.
The Impact on Dental Health
One of the most immediate and visible consequences of drinking Mountain Dew is the risk to dental health. The combination of high sugar and citric acid is a potent recipe for enamel erosion and tooth decay. The phenomenon has been colloquially dubbed "Mountain Dew Mouth" and is associated with extensive cavities and visible dental issues.
- Enamel Erosion: The high acidity, with a pH lower than many other popular sodas, softens tooth enamel over time.
- Cavity Formation: Sugar feeds the bacteria in the mouth, which in turn produce more acid, accelerating the decay process.
- Increased Sensitivity: As enamel wears away, the sensitive inner layers of the teeth are exposed, leading to increased pain and discomfort.
Unsettling Artificial Ingredients
Beyond the obvious sugar and acid, Mountain Dew also contains several controversial artificial ingredients that have fueled public health concerns and are regulated differently worldwide.
- Brominated Vegetable Oil (BVO): Used as an emulsifier to keep the citrus flavor distributed, BVO is a flame retardant chemical that has been banned in food products across Europe and Japan. It is known to build up in the body and can potentially cause organ and neurological damage with long-term exposure.
- Yellow Dye #5 (Tartrazine): This artificial food coloring has been linked to behavioral problems in some children and increased allergies. While still allowed in the U.S., it faces heavy scrutiny and even restrictions in other countries.
- Sodium Benzoate: When combined with citric acid, the preservative sodium benzoate can form benzene, a known carcinogen. While the amount is typically small, regular consumption over time raises concerns.
Comparison Table: Mountain Dew vs. Other Sodas
To put Mountain Dew's composition into perspective, here is a comparison with other popular carbonated beverages based on a standard 12-ounce serving.
| Feature | Mountain Dew | Coca-Cola | Sprite | Pepsi |
|---|---|---|---|---|
| Sugar (g) | 46 | 39 | 38 | 38 |
| Caffeine (mg) | 54 | 34 | 0 | 38 |
| Calories | 170 | 140 | 140 | 150 |
| pH Level | ~3.2 | ~2.5 | ~3.2 | ~2.4 |
| BVO | Yes | No | No | No |
Note: pH levels are approximate and can vary slightly.
Health Effects Beyond Teeth
The high sugar content of Mountain Dew contributes to broader metabolic and weight-related health problems. Regular consumption of sugary drinks is a known risk factor for obesity, type 2 diabetes, and high cholesterol. The high caffeine content can also lead to issues with sleep, increased heart rate, and dependence. Furthermore, studies indicate that regularly consuming such high amounts of sugar can affect mood, energy levels, and overall gut health.
The Verdict: Moderation is Key
While the occasional indulgence is unlikely to cause serious harm, the consensus among health experts is to avoid Mountain Dew and similar sugary drinks as a regular part of one's diet. The accumulation of effects from high sugar, acid, and potentially harmful artificial ingredients makes it a beverage to be consumed in strict moderation, if at all. Opting for healthier alternatives like water, sparkling water with natural fruit, or herbal tea is a far safer choice for long-term health and wellness. For those struggling to break the habit, strategies like using a straw to minimize tooth contact, drinking water immediately after, and waiting before brushing can help mitigate some damage. Ultimately, the reasons people say not to drink Mountain Dew are founded on clear and well-documented nutritional drawbacks and ingredient concerns.
Conclusion: A Clear Picture of Risk
The widespread advice to avoid Mountain Dew is not based on sensationalism but on a collection of genuine health concerns. From its damaging impact on dental enamel and high sugar content linked to obesity and diabetes, to the presence of controversial additives like BVO, the beverage presents a multitude of reasons for caution.

Making informed choices about what we consume, and understanding why a popular product might have a negative reputation, is a crucial step towards maintaining a healthier lifestyle. The health community's message is consistent: limit your intake of sugary sodas to protect your body from preventable harm.
