While the term 'chemicals' can sound intimidating, all food is made of chemical compounds, whether natural or synthetic. Mountain Dew is no exception, and its distinctive taste and bright color are the result of a specific blend of ingredients. By exploring these components, consumers can better understand what is in their favorite soda.
The Primary Components
At its core, Mountain Dew is a sugary, carbonated beverage, meaning the main ingredients are carbonated water and a sweetener. In the U.S., this sweetener is primarily high fructose corn syrup (HFCS), a processed sugar. Some international versions or limited-edition varieties use natural sugar instead. Concentrated orange juice is also a key ingredient, providing a base for the citrus flavor.
Additives for Flavor, Preservation, and Color
Various additives are used to achieve Mountain Dew's specific taste, extend its shelf life, and give it its vibrant color.
Flavor Enhancers and Preservatives
Citric acid adds a tart taste and acts as a preservative. A proprietary blend of "Natural Flavor" creates the unique profile. Preservatives such as Sodium Benzoate, Erythorbic Acid, and Calcium Disodium EDTA inhibit microbial growth, preserve freshness, and protect flavor. Sodium Citrate is included as an acidity regulator and flavor enhancer.
Controversial Additives: Past and Present
The bright yellow-green color comes from Yellow 5, also known as Tartrazine (E102). This artificial dye has been linked to allergic reactions and hyperactivity, requiring a warning label in some parts of Europe. Brominated Vegetable Oil (BVO), previously used to prevent flavor separation, was banned in many countries and recently removed from Mountain Dew in the U.S. following health concerns and public pressure. Caffeine, a stimulant, is also a significant component, with a 12-ounce can containing approximately 54 mg.
Comparison of Mountain Dew vs. Diet Mountain Dew Ingredients
The key difference between regular and Diet Mountain Dew lies in the sweetener used, impacting calorie content. Both share some preservatives and artificial colors, though specific preservatives may vary. Other additives like Gum Arabic or Citrus Pectin also differ.
| Feature | Regular Mountain Dew | Diet Mountain Dew |
|---|---|---|
| Sweetener | High Fructose Corn Syrup | Aspartame, Acesulfame Potassium, Sucralose |
| Calories | Approximately 170 per 12 oz | Zero |
| Preservatives | Sodium Benzoate, Erythorbic Acid, Calcium Disodium EDTA | Potassium Benzoate, Sodium Benzoate, Calcium Disodium EDTA |
| Other Additives | Gum Arabic, Natural Flavor, Concentrated Orange Juice | Citrus Pectin, Natural Flavor, Concentrated Orange Juice |
| Artificial Colors | Yellow 5 | Yellow 5 |
The Big Picture: Nutritional Concerns
Beyond individual ingredients, the overall nutritional impact of Mountain Dew, as an ultra-processed food high in sugar, is a major health consideration. Regular consumption is linked to increased risks of obesity, type 2 diabetes, and cardiovascular issues. The high acidity can also damage tooth enamel. Variations in ingredients globally highlight differing food regulations and consumer expectations.
Conclusion
Mountain Dew's composition involves a blend of primary ingredients and additives to achieve its unique flavor and appearance. Understanding these components, including the removal of BVO and the presence of Yellow 5 and high fructose corn syrup, helps consumers make informed choices regarding its health implications. Its high sugar content and status as an ultra-processed food underscore the importance of considering its overall nutritional impact.
