Does Mountain Dew have any side effects? A comprehensive look

4 min read

According to the American Heart Association, a single 12-ounce can of Mountain Dew contains 46 grams of sugar, exceeding the daily recommended limit for most adults. This high sugar content is just one factor contributing to the numerous potential side effects of Mountain Dew consumption.

Quick Summary

Excessive Mountain Dew intake can lead to serious health issues due to high sugar, caffeine, and acidic content. Potential risks include significant tooth decay, weight gain, metabolic issues like Type 2 diabetes, heart complications, and caffeine-related side effects such as anxiety and sleep disruption.

Key Points

  • High Sugar Content: A single 12-ounce can of Mountain Dew contains 46 grams of sugar, mostly from High Fructose Corn Syrup, contributing to weight gain and Type 2 Diabetes risk.

  • Severe Dental Erosion: The drink’s combination of high sugar and citric acid can lead to a condition known as 'Mountain Dew Mouth,' causing significant enamel erosion and cavities.

  • Excessive Caffeine: With 54mg of caffeine per 12oz can, Mountain Dew can cause jitters, anxiety, sleep disruption, and dependence with regular consumption.

  • Concerning Additives: Ingredients like artificial Yellow 5 dye have been linked to behavioral issues, and some older formulations contained Brominated Vegetable Oil (BVO), a controversial additive.

  • Diet Version Risks: Diet Mountain Dew, while calorie-free, poses its own risks due to artificial sweeteners, which may disrupt gut health and be linked to metabolic issues and weight gain.

  • Healthier Alternatives Exist: Opting for sparkling water, kombucha, or unsweetened iced tea is a safer choice for those seeking a bubbly or caffeinated drink.

The High Sugar and Fructose Corn Syrup Problem

One of the most significant concerns with Mountain Dew is its exceptionally high sugar content. A 12-ounce serving packs 46 grams of sugar, nearly double the recommended daily limit for women and exceeding the limit for men. Much of this comes from High Fructose Corn Syrup (HFCS), a controversial sweetener linked to a host of health problems.

Impact on weight and metabolism

  • Significant Weight Gain: Liquid calories from sugary drinks like Mountain Dew are easily over-consumed, leading to excess calorie intake and fat storage, especially around the abdomen.
  • Increased Diabetes Risk: The rapid spikes in blood sugar caused by HFCS can lead to insulin resistance over time, dramatically increasing the risk of developing Type 2 Diabetes.
  • Elevated 'Bad' Cholesterol: High intake of HFCS is also associated with elevated levels of 'bad' cholesterol (LDL), a risk factor for heart disease.

Serious Concerns for Dental Health

Mountain Dew's impact on dental health is so severe it has earned its own nickname: "Mountain Dew Mouth". This condition refers to the severe tooth decay resulting from the drink's powerful combination of sugar and high acidity. The high citric acid content softens tooth enamel, while the sugar feeds bacteria that produce more acid, creating a perfect storm for cavities.

  • Erosion and Sensitivity: The high acidity erodes tooth enamel, leaving teeth vulnerable to sensitivity, decay, and discoloration.
  • Aggravated by Prolonged Sipping: Many consumers sip soda over long periods, prolonging the acid attack on their teeth and exacerbating the damage.
  • Cavity Amplification: The abundant sugar provides a feast for bacteria, which produces more enamel-damaging acid and accelerates the cavity formation process.

The Caffeine Conundrum

Mountain Dew contains a considerable amount of caffeine, with a 12-ounce can having about 54mg—significantly more than the same size serving of Coke. While caffeine can provide a temporary energy boost, it comes with a list of potential drawbacks, especially with regular consumption.

Common caffeine-related side effects

  • Anxiety and Jitters: High doses of caffeine can trigger anxiety, restlessness, and jitters, particularly in sensitive individuals.
  • Sleep Disruption: Consuming Mountain Dew late in the day can interfere with your sleep cycle, leading to insomnia and poor sleep quality.
  • Dependency and Withdrawal: Regular high caffeine intake can lead to dependence, resulting in headaches, fatigue, and irritability upon withdrawal.

Other Concerning Ingredients and Their Effects

Beyond sugar and caffeine, Mountain Dew contains several other ingredients that have raised health alarms over the years.

Artificial colors and preservatives

  • Yellow 5 (Tartrazine): This artificial dye has been linked to behavioral problems in children and allergic reactions.
  • Sodium Benzoate: When combined with ascorbic acid (vitamin C), this preservative can form benzene, a known carcinogen, though this is less common in modern formulations.
  • Brominated Vegetable Oil (BVO): Formerly a common ingredient, BVO is a flame retardant that was used as an emulsifier. Although now phased out by many major beverage makers, it was banned in over 100 countries due to its potential for toxic effects, including organ and neurological damage.

Regular vs. Diet Mountain Dew: A Comparison

While the high-sugar content is a primary concern for regular Mountain Dew, its diet counterpart is not without its own set of potential side effects, primarily stemming from artificial sweeteners.

Comparison Table: Regular vs. Diet Mountain Dew Risks

Factor Regular Mountain Dew (HFCS) Diet Mountain Dew (Artificial Sweeteners)
Sugar/Sweetener High Fructose Corn Syrup Aspartame, Acesulfame Potassium, etc.
Calories High (170 per 12oz can) Zero
Weight Gain Risk High due to excess calories Mixed research; may disrupt appetite and metabolism, increasing cravings
Dental Erosion High due to high acidity and sugar High due to high acidity (citric acid)
Metabolic Risk High risk of Type 2 Diabetes Associated with metabolic syndrome and Type 2 Diabetes risk
Gut Health Can harm gut microbiome due to sugar Can disrupt gut microbiome with artificial sweeteners
Neurological Effects Potential for caffeine-induced anxiety Aspartame linked to headaches, anxiety, and mood changes in some
Cardiovascular Risk Increased risk due to weight gain, high cholesterol Associated with increased risk of heart disease and stroke

Healthier Alternatives to Mountain Dew

For those looking to reduce their soda consumption and mitigate health risks, several healthier and flavorful alternatives exist.

Health-conscious beverage options

  • Sparkling Water with Natural Flavor: Brands like Spindrift or LaCroix offer the fizz without the high sugar and questionable additives. You can also infuse plain sparkling water with fresh fruit or herbs.
  • Kombucha: This fermented tea provides a probiotic boost for gut health and has a fizzy kick, though sugar content can vary by brand.
  • Unsweetened Iced Tea: A low-calorie and flavorful option, iced tea provides a caffeine boost without the added sugars and acids.
  • Naturally Flavored Water Enhancers: Products like MiO or Waterdrop allow you to add flavor to your water with fewer concerns than artificial sweeteners.

Conclusion

While Mountain Dew is a popular beverage, its regular consumption carries significant and well-documented side effects. The combination of high sugar, elevated caffeine, high acidity, and concerning artificial additives can lead to serious dental issues, weight gain, metabolic disorders, and cardiovascular risks. While diet versions offer a calorie-free alternative, they introduce other potential health concerns related to artificial sweeteners. Choosing healthier beverages, especially water, remains the safest and most beneficial option for long-term health. Moderation is key if you choose to indulge, along with proactive dental hygiene to combat the corrosive effects.
