Understanding Calorie Content in Mountain Dew
With its bright green color and unique citrus flavor, Mountain Dew has been a popular soft drink choice for decades. But like most sodas, Mountain Dew packs a lot of extra calories and sugar into each can or bottle. For health-conscious consumers who still enjoy an occasional Mountain Dew, it's helpful to understand exactly what you're consuming in terms of calories.
When looking at the calorie content of Mountain Dew, most packaging labels and nutrition facts provide information for a standard 12-ounce can or 20-ounce bottle. To determine the calories in a full liter of Mountain Dew, which is approximately 33.8 ounces, we need to do a little math based on the typical calorie count per serving.
Calories in a 12-ounce Can of Mountain Dew
A standard 12-ounce can of regular (not diet) Mountain Dew contains the following nutrition facts:
- 150 calories
- 54 grams of sugar
- 54 milligrams of caffeine
- 0 grams of fat, protein or fiber
So a single can contains 150 calories. Since there are approximately 2.8 cans in one liter, if we multiply 150 calories by 2.8, we can estimate that there are around 420 calories in 1 liter of regular Mountain Dew.
Calories in a 20-ounce Bottle of Mountain Dew
Now let's look at a larger standard serving size - the 20-ounce plastic bottle:
- 240 calories
- 77 grams of sugar
- 91 milligrams of caffeine
- 0 grams of fat, protein or fiber
One 20-ounce bottle has 240 calories. Since there are about 1.7 bottles in one liter, if we multiply 240 by 1.7, there are approximately 408 calories in 1 liter of Mountain Dew when extrapolating from the 20-ounce bottle nutrition information.
Factors Impacting Exact Calorie Content
As you can see from the two serving sizes above, the estimated number of calories in a full liter of Mountain Dew is around 400-420 calories on average. However, there are a few factors that can slightly impact the exact calorie content per liter:
- Variations in soda volume from bottling differences
- Slight recipe variations in different global regions
- Changes to soda formulas over time
Additionally, there are different varieties of Mountain Dew beyond just the classic original flavor. Diet Mountain Dew contains zero calories, while Code Red, Voltage, and LiveWire have 10-20 extra calories per serving compared to original.
Mountain Dew Nutrition Facts Breakdown
Now that we've looked at the overall calorie content, let's break down the key nutrition facts and ingredients behind Mountain Dew's high-calorie count:
High-Fructose Corn Syrup
Like most mainstream sodas, the number one ingredient in Mountain Dew is high-fructose corn syrup (HFCS). HFCS is a heavily processed sweetener derived from corn starch. A 12-ounce can of Mountain Dew gets 46 grams of sugar and 150 calories just from the HFCS alone. HFCS is broken down rapidly by the body, causing blood sugar and insulin spikes.
Caffeine Content
In addition to HFCS, Mountain Dew contains caffeine for an extra energy boost. There are 54 milligrams of caffeine in a 12-ounce can.
While this amount is less than a cup of coffee, caffeine combined with the sugar content adds to the overall stimulating effect of Mountain Dew.
Carbonated Water
The other key ingredient is carbonated water, which gives Mountain Dew its bubbly, effervescent texture. The combination of carbonated water, HFCS, caffeine, and citrus flavoring create the drink's signature sweet and slightly tart taste.
Artificial Colors
Mountain Dew gets its bright neon green color from artificial food dyes Yellow #5 and Yellow #6. These synthetic dyes have been linked to allergies and sensitivity reactions in some people.
Brominated Vegetable Oil
Brominated vegetable oil (BVO) is an additive used to prevent citrus flavoring from separating in some citrus-flavored sodas. While BVO has been removed from many popular sodas like Gatorade, it is still found in some Mountain Dew varieties.
Minimal Nutritional Value
Beyond calories, sugar, and caffeine, there is very minimal nutritional value in Mountain Dew. A 12-ounce can provides no protein, vitamins, minerals, or antioxidants. So the 400+ calories in a liter of soda are mostly "empty" calories.
Health Impacts of Drinking 1 Liter of Mountain Dew
Now that we see how many calories are packed into a liter of Mountain Dew, what does this actually mean for your health? Here are some potential impacts of drinking around 400 calories of Mountain Dew in one sitting:
Blood Sugar Spike
With its concentrated dose of quickly absorbed HFCS and lack of fiber or fat, Mountain Dew can cause a rapid spike in blood glucose and insulin levels.
For people with diabetes or pre-diabetes, this blood sugar rollercoaster can be concerning and requires careful monitoring of carbohydrate intake from sugary sodas.
Weight Gain
At around 400 calories, a liter of Mountain Dew accounts for almost 20% of the recommended daily calorie intake for women and around 15% for men. Taken in addition to one's normal food intake, those extra calories can quickly lead to weight gain over time.
To burn off 400 calories, an average adult would need to walk for about 90 minutes at a moderate pace. Without equivalent exercise to offset the extra calories, drinking large amounts of soda sets the stage for obesity.
Tooth Decay
The combination of sugar and acidity in Mountain Dew can erode tooth enamel over time, increasing the risk of cavities and dental decay.
Sipping slowly, using a straw, and rinsing mouth with water can help minimize contact between soda and teeth. But frequent consumption still threatens oral health.
Caffeine Sensitivity
While 54 milligrams of caffeine per can may not seem high compared to coffee, less caffeine-habituated people can still feel jittery or anxious after consuming several cans worth in a liter of Mountain Dew.
Those especially sensitive to caffeine may want to opt for caffeine-free varieties or limit intake to a modest 4-6 ounces.
Crashing Blood Sugar
After the initial blood sugar spike, a liter of Mountain Dew can then lead to a blood sugar crash as insulin causes rapid transport of glucose out the bloodstream. This rollercoaster effect can cause fatigue, irritability, and increased sugar cravings.
Strategies for Drinking Mountain Dew in Moderation
Does this mean you need to give up your favorite neon green soda for good? Not necessarily. With some smart strategies, you can still enjoy moderate amounts of Mountain Dew without adverse health effects:
Dilute with Seltzer
Try diluting your Mountain Dew with plain seltzer water. This cuts down on the overall calories and sweetness while maintaining the citrus flavor.
Alternate with Water
When drinking a liter of Mountain Dew, also drink plenty of plain water in between to stay hydrated and prevent blood sugar spikes.
Watch Portion Sizes
Stick to a reasonably sized serving of 12-20 ounces rather than an entire liter in one sitting. Spread out consumption with no more than 12-24 ounces per day.
Choose Diet or Zero Sugar
Try the zero calorie Diet Mountain Dew or newly formulated Zero Sugar version to enjoy the flavor without the extra calories or carbohydrate impact.
Save for Special Occasions
Make Mountain Dew an occasional treat rather than a daily habit. Consume more judiciously at special events or as a weekend indulgence.
Regulate Caffeine Intake
Monitor your overall caffeine consumption from all beverage sources, including coffee, tea, energy drinks, and soda. Aim to stay below the recommended limit of 400 mg per day.
Exercise Portion Control
When drinking Mountain Dew, portion into a measured glass rather than drinking straight from the bottle or 2-liter container. This helps you stay aware of exactly how much you are consuming.
The Role of Soda in a Healthy Lifestyle
When consumed in moderation alongside an otherwise balanced diet and active lifestyle, an occasional Mountain Dew can be incorporated into a healthy regimen for most people.
The key is being mindful of just how little nutritional value yet how many empty calories soda delivers. Being informed about the calorie content per serving and per liter allows you to stay in control of your intake.
Rather than strictly banning soda from your life, aspire to the 80/20 principle — make water, unsweetened tea, coffee, milk and fresh juices about 80% of your daily beverage choices, with less nutritious drinks like Mountain Dew saved for the remaining 20% of the time.
By keeping soda as an occasional treat rather than an everyday habit, and complementing each serving with good hydration, you can satisfy your cravings while minimizing negative impacts on your health.
