The Immediate and Acute Effects
Drinking a Mountain Dew delivers an instant, and for many, noticeable effect on the body. This is primarily due to its high levels of sugar and caffeine, which trigger a series of physiological responses. The immediate effects are often what attract consumers, but they are also the first sign of the beverage's downsides.
The Sugar Rush and Subsequent Crash
A single 12-ounce can of Mountain Dew contains 46 grams of sugar, primarily in the form of high-fructose corn syrup. This large, concentrated dose of sugar causes a rapid spike in blood sugar levels. The body responds with a flood of insulin to process the sugar, which often results in a rapid drop in blood sugar, or a 'crash,' leaving the drinker feeling fatigued and irritable. Over time, this constant fluctuation can contribute to insulin resistance and increase the risk of type 2 diabetes.
The Caffeine Kick and Its Fallout
With 54 milligrams of caffeine per 12-ounce serving, Mountain Dew offers a higher caffeine dose than many other sodas. This stimulant can increase heart rate, raise blood pressure, and lead to feelings of jitteriness or anxiety. In sensitive individuals or with large, frequent consumption, it can also cause sleep disruptions and digestive issues, such as stomach upset or diarrhea. While the boost in alertness can be a temporary benefit, it comes at a cost of potential dependency and disrupted sleep cycles.
Chronic and Long-Term Health Risks
Regular, long-term consumption of Mountain Dew can have more serious, cumulative effects on the body. The combination of high sugar, acidity, and artificial ingredients contributes to a range of chronic health problems.
Oral Health and "Mountain Dew Mouth"
The term "Mountain Dew mouth" refers to the severe tooth decay associated with regular consumption of the soda. This is caused by two main factors working in tandem:
- High Acidity: Mountain Dew has a pH level of around 3.1, making it more acidic than Coke. The high concentration of citric acid erodes tooth enamel, the protective outer layer, leaving teeth vulnerable.
- Sugar Content: The sugar feeds bacteria in the mouth, which in turn produce more acid, accelerating the decay process and leading to cavities.
The prolonged exposure to this acidic and sugary environment can cause increased tooth sensitivity, discoloration, and significant dental damage.
Weight Gain and Metabolic Syndrome
The 170 calories and 46 grams of sugar in a single can contribute to weight gain and obesity when consumed frequently. This excess sugar is often converted into fat by the liver and stored in the body, particularly around the midsection. Obesity, in turn, is a major risk factor for a host of metabolic problems, including type 2 diabetes and high blood pressure.
Effects on the Kidneys and Bones
Some evidence suggests that excessive intake of carbonated beverages, particularly those containing high levels of phosphoric acid, can negatively affect kidney and bone health. Phosphoric acid has been linked to potential bone density reduction by interfering with calcium absorption, increasing the risk of osteoporosis. For the kidneys, the processing of excess phosphorus and the metabolic strain from high sugar intake can lead to increased risk of chronic kidney disease, especially in those with pre-existing conditions.
A Comparison of Popular Sodas

| Key Concern | Highest sugar, caffeine, and acidity | High sugar and acidity, potential caramel color concerns | Artificial sweeteners and their potential effects |
Understanding the Ingredients
The Problem with Artificial Additives
While regular Mountain Dew is packed with high fructose corn syrup and food dyes, Diet Mountain Dew swaps the sugar for artificial sweeteners like aspartame and sucralose. While this removes the sugar and calorie content, these sweeteners are not without controversy. Some studies suggest that artificial sweeteners can alter the gut microbiome and potentially increase the risk of metabolic dysfunction over time. Diet soda consumption has also been linked to an increased risk of heart-related issues and may contribute to cravings for sweeter foods.
The BVO Controversy
Brominated vegetable oil (BVO), an emulsifier used in regular and diet Mountain Dew to keep flavorings suspended, has been subject to health concerns and is banned in over 100 countries. BVO contains bromine, a halogen that can accumulate in the body over time. Though classified as safe by the FDA at low levels, potential toxic effects like organ damage and neurological issues have been raised in animal studies.
Conclusion: A High-Risk Beverage
For a brief jolt of energy, Mountain Dew delivers due to its high caffeine and sugar content. However, the immediate sugar crash and long-term health consequences make it a high-risk choice for regular consumption. The potent combination of sugar, citric acid, and caffeine poses significant threats to dental health, while frequent intake is linked to weight gain, metabolic syndrome, and increased risks of chronic conditions like type 2 diabetes and heart disease. Even the "diet" version carries potential risks associated with artificial sweeteners and controversial additives like BVO. The most responsible choice for your health is to reserve Mountain Dew as a rare treat and prioritize healthier hydration options like water.
Reducing Your Risk
If you choose to consume sugary sodas like Mountain Dew, dentists and health experts recommend several harm-reduction strategies:
- Drink in moderation and avoid sipping throughout the day.
- Use a straw to minimize contact with your teeth.
- Rinse your mouth with water afterward to neutralize some of the acid.
- Wait at least 30 to 60 minutes before brushing your teeth to avoid damaging softened enamel.
Frequently Asked Questions
Q1: Is Mountain Dew worse for your teeth than other sodas?
A: Yes. Mountain Dew has a higher sugar content and is more acidic than many other sodas, including Coke. This combination makes it exceptionally damaging to tooth enamel and significantly increases the risk of cavities and discoloration.
Q2: Can Mountain Dew lead to weight gain?
A: Yes, regular consumption can lead to weight gain. A single 12 oz can contains 170 empty calories and a very high sugar content, which can contribute to obesity and metabolic issues over time.
Q3: How does Mountain Dew affect your heart rate?
A: The high caffeine content in Mountain Dew can increase heart rate and blood pressure, potentially causing palpitations or irregular heart rhythms in sensitive individuals.
Q4: Are the artificial sweeteners in Diet Mountain Dew safe?
A: While generally recognized as safe in moderation, artificial sweeteners like aspartame and sucralose have been linked to potential issues with gut health and metabolic function. Some studies also show a link to an increased risk of cardiovascular diseases with long-term use.
Q5: What is Brominated Vegetable Oil (BVO) in Mountain Dew?
A: BVO is a flame retardant chemical used as an emulsifier in Mountain Dew. While the FDA allows it in small amounts, it is banned in many other countries due to potential toxic effects and its tendency to accumulate in the body.
Q6: Can drinking Mountain Dew cause diabetes?
A: Regular, high consumption of sugary sodas is strongly linked to an increased risk of developing type 2 diabetes due to constant blood sugar spikes and potential insulin resistance.
Q7: Are there healthier alternatives to Mountain Dew?
A: Healthier alternatives include water, sparkling water flavored with natural fruit, herbal teas, or kombucha. These options provide hydration and flavor without the excessive sugar, caffeine, and artificial ingredients.
Q8: Does Mountain Dew affect male fertility?
A: There is no credible scientific evidence to support the myth that Mountain Dew kills sperm or affects male fertility. The claim is based on misinformation and the yellow dye, but this has been debunked by medical experts.
Q9: Does Mountain Dew affect your mental health?
A: The sugar highs and crashes from Mountain Dew can lead to mood swings. Additionally, high caffeine intake can cause irritability, restlessness, and anxiety.
Q10: What is the main problem with drinking Mountain Dew regularly?
A: The main problem is the combined impact of its high sugar, high acidity, and significant caffeine content, which poses major long-term health risks to dental, metabolic, and cardiovascular health.
