The Immediate Impact of Mountain Dew
Consuming Mountain Dew, with its high sugar and caffeine content, results in immediate effects on the body. The sugar, often from high fructose corn syrup, causes a rapid blood sugar increase and a temporary energy boost, which is typically followed by an energy crash. This can contribute to unhealthy eating patterns and weight gain. The 54mg of caffeine in a 12-ounce can acts as a stimulant, increasing alertness but potentially leading to jitters, anxiety, and sleep issues, especially with multiple servings. Caffeine can also cause a temporary rise in blood pressure.
Long-Term Effects on Key Body Systems
Oral Health: The Notorious 'Mountain Dew Mouth'
The high sugar and citric acid in Mountain Dew are a significant threat to dental health, a condition sometimes referred to as 'Mountain Dew Mouth'. The drink's high acidity (pH ~3.3) erodes tooth enamel, while bacteria in the mouth feed on the sugar, producing more enamel-damaging acid. Frequent consumption means continuous exposure of teeth to this damaging environment, increasing the risk of cavities, sensitivity, gum disease, and tooth loss.
Metabolic and Cardiovascular Health
Regularly drinking high-sugar sodas like Mountain Dew increases the risk of chronic health problems. It contributes to weight gain and obesity due to its empty calories. High sugar intake can impair blood sugar regulation, raising the risk of type 2 diabetes. Furthermore, excessive sugar is linked to unfavorable changes in blood lipids, increasing the risk of heart disease.
Kidney and Bone Health
There is ongoing research into a potential link between soda consumption and kidney disease. Phosphoric acid in sodas may also hinder calcium absorption, potentially weakening bones over time, particularly for individuals with low calcium intake.
Digestive Health
The carbonation in Mountain Dew can cause digestive discomfort like bloating and gas, especially in individuals with conditions like acid reflux. The high sugar can also negatively impact the balance of gut bacteria.
Comparison: Mountain Dew vs. Healthier Alternatives
Examining the nutritional content highlights the issues with Mountain Dew compared to healthier drink choices:
| Feature | 12oz Can of Mountain Dew | 12oz of Flavored Seltzer | 12oz of Iced Green Tea (Unsweetened) |
|---|---|---|---|
| Calories | ~170 kcal | 0 kcal | ~0 kcal |
| Added Sugar | 46g | 0g | 0g |
| Caffeine | 54mg | 0mg | ~25-50mg (varies) |
| Acidity (pH) | ~3.3 | ~5.0-6.0 | ~7.0 |
| BVO | Historically included | No | No |
| Overall Impact | High risk for dental, metabolic, and weight issues. | Low risk, good hydration. | Low risk, contains antioxidants. |
Ingredients of Concern
Mountain Dew has contained controversial ingredients such as Brominated Vegetable Oil (BVO), a substance banned in several countries due to potential toxicity, though reportedly removed from some formulations. It also contains high fructose corn syrup and artificial colors, like Yellow 5, which has been associated with behavioral issues in children. More detailed information on these and other ingredients can be found through resources like the Cleveland Clinic Health Essentials: What Is Mountain Dew Mouth?.
Conclusion: Moderation is Key
While an occasional Mountain Dew is unlikely to cause serious harm, regular consumption poses significant risks to health due to its high sugar, caffeine, and acidity. These factors can negatively impact oral health, metabolism, and overall well-being. Choosing healthier alternatives such as water, unsweetened tea, or sparkling water is a better option for long-term health. Understanding what Mt Dew does to the body is crucial for making informed hydration choices and maintaining a healthy lifestyle.
