Editor's review: Mountain Dew Zero Sugar vs. Diet Mountain Dew vs. Mountain Dew: Which is the Best Choice?

While there are many different opinions, my first choice is Diet Mountain Dew.

• First, it does not contain the added sugar found in high-fructose corn syrup, which fits the low-sugar, low-carb, low-calorie diet trend. Zero sugar intake helps reduce some health risks, such as weight gain, frequent acne, and increased blood pressure.

• Second, Diet Mountain Dew has a light citrus flavor but isn’t too sweet. Mountain Dew is a little too sweet for me. Since it's designed to mimic the original flavor, of course Zero Sugar is also sweet, but slightly milder than the original flavor. Diet Mountain Dew has a rounder flavor and Zero Sugar has a slightly more tart flavor.

• Third, Diet Mountain Dew has a relatively low caffeine content. Even if you drink four cans a day, you will not suffer from headaches, insomnia, rapid heartbeat, nervousness and other problems. Mountain Dew Zero Sugar has the most caffeine. Mountain Dew Zero Sugar contains 68 mg of caffeine in a 12 fl oz can. Energy drink lovers may like this.

• Fourth, Diet Mountain Dew contains real orange juice in its ingredient list. Although I can't explain anything, I feel that its quality is better.

The Origin of Mountain Dew

Mountain Dew, known as Mtn Dew in some countries, is a carbonated soft drink brand produced and owned by PepsiCo.

The original recipe was created in 1940 by Tennessee beverage bottlers Barney and Ally Hartman.

Its competitors include Coca-Cola Co.'s Mello Yello and Keurig Dr Pepper's Sun Drop, but Mountain Dew ranks No. 1 in U.S. citrus soft drink sales.

The Origin of Diet Mountain Dew

Diet Mountain Dew was first launched in 1984 as Sugar-Free Mountain Dew and was later renamed Diet Mountain Dew.

Diet Mountain Dew is a variation of Mountain Dew that has only 4 calories compared to the original's 170 calories and is sweetened with artificial sweeteners instead of high fructose corn syrup.

The Origin of Mountain Dew Zero Sugar

Mountain Dew Zero Sugar was first leaked on the Dew Drinker Discord on September 11, 2019, planning to get released in some sizes.

Months after being leaked, it was officially released in stores nationwide as a permanent flavor on January 13, 2020, in various sizes such as 20-ounce Sidekick bottles, 24-ounce bottles, and 16-ounce/16.9-ounce multi-pack bottles , 1 liter bottles, 2 liter bottles, 12-packs, 24-packs.

In the first half of 2024, Mountain Dew Zero Sugar was launched in Taco Bell restaurants, replacing Diet Mountain Dew's spot on fountain machines.

Diet Mountain Dew and Mountain Dew Zero Sugar vs. Regular Mountain Dew: What are the main differences?

>> Low calorie, no calorie, no sugar

Both drinks, Diet Mountain Dew and Mountain Dew Zero Sugar, are sugar-free alternatives to regular Mountain Dew.

Unlike regular Mountain Dew, which contains added sugar, the sugar-free version of Mountain Dew uses artificial sweeteners to sweeten it, since drinking too much added sugar can cause people to consume too many calories, which can lead to weight gain.

In addition, a high-sugar diet may lead to health problems such as obesity, fatty liver disease, high blood pressure, acne, type 2 diabetes, and heart disease.

Diet Mountain Dew vs. Mountain Dew Zero Sugar: What are the main differences?

Here’s a comparison of the key differences between Diet Mountain Dew and Mountain Dew Zero Sugar:

>> Diet Mountain Dew vs. Mountain Dew Zero Sugar: Sweeteners

Diet Mountain Dew and Mountain Dew Zero Sugar use almost the same artificial sweeteners. They both contain three sweeteners; they both use aspartame, acesulfame potassium, and sucralose for sweetening.

A 12-ounce can of Mountain Dew contains 46 grams of sugar. This is at the top end of soda's sugar content. The U.S. Food and Drug Administration (FDA) considers all three sweeteners safe.

Aspartame is a low-calorie sweetener that delivers the sweet taste you love without increasing your calorie intake.

Acesulfame potassium is a non-caloric sweetener used in foods and beverages to provide sweetness. Acesulfame potassium can also be added to other sweeteners, such as aspartame, to prolong sweetness and help reduce bitterness and aftertaste.

Sucralose is a no-calorie sweetener that can be used to lower one’s intake of added sugars while still providing satisfaction from enjoying the taste of something sweet.

>> Diet Mountain Dew vs Mountain Dew Zero Sugar: Ingredients

While the difference in sweeteners isn't dramatic, Diet Mountain Dew and Mountain Dew Zero Sugar do have slightly different ingredient lists.

Diet Mtn Dew contains orange juice concentrate, while Mtn Dew Zero Sugar does not contain orange juice concentrate.

Since orange juice is very high in calories, I guess Mtn Dew Zero Sugar removed orange juice because it wanted to provide a truly zero sugar and zero calorie drink.

>> Diet Mountain Dew vs. Mountain Dew Zero Sugar: Taste

Mountain Dew Zero Sugar is designed to more closely mimic the taste of regular Mountain Dew. Mountain Dew is one of the sweetest carbonated drinks in the world, so of course, Mountain Dew Zero Sugar isn't any less sweet.

Since both Diet Mtn Dew and Mtn Dew Zero Sugar are sweetened with aspartame, they both leave an aftertaste that is not as natural as original Mtn Dew. While Mountain Dew Zero Sugar is just as sweet as regular Mountain Dew, it doesn't have as long of a sweet aftertaste.

The drinks are the same color, but Zero Sugar takes on a slightly sharper citrus flavor. Zero Sugar is more lemony and Diet is more limey.

In terms of carbonation, Diet Mountain Dew has the highest level of carbonation, followed by Mountain Dew, while Mountain Dew Zero Sugar has the lowest level of carbonation. The result is that Mountain Dew Zero Sugar is smoother and easier to swallow because it doesn't cause a stinging sensation on the throat.

>> Diet Mountain Dew vs. Mountain Dew Zero Sugar: Calorie Content

Diet Mountain Dew is low in calories, making it an excellent choice for those looking for a soda that won't add calories.

Calorie and sugar-conscious consumers may have noticed some weirdness with the calorie counts for various sizes of Diet Mountain Dew. A 12-ounce can will have 0 calories, but larger serving sizes will have 5, or even 10 calories. This is because the FDA requires companies to round to the nearest 5 calories, with anything below 5 calories per serving able to be stated as 0.

Mountain Dew Zero Sugar is zero calories, making it the perfect choice for those who strictly monitor their calorie intake or follow a calorie-restricted diet.

>> Diet Mountain Dew vs. Mountain Dew Zero Sugar: Caffeine Content

Another difference between these two drinks is their caffeine content.

A 12-ounce can of Diet Mountain Dew contains 54 mg of caffeine, while Mountain Dew Zero Sugar contains 68 mg of caffeine. By comparison, a can of regular Mountain Dew contains 54 milligrams of caffeine.

So why does Mountain Dew Zero Sugar contain more caffeine than other versions of Mountain Dew?

Caffeine is used to enhance the flavor of the drink and is said to add a hint of bitterness to balance out other elements.

So Mountain Dew Zero Sugar will taste richer and sweeter, while Diet Mountain Dew will taste less sweet.

With its high caffeine level, Mtn Dew has the advantage of straddling the soda and the energy drink market. This may appeal to those looking for drinks that provide functional benefits.
