The Core Components: Mountain Dew vs. Water
To understand if Mountain Dew counts as water, one must look beyond the initial hydrating sensation and examine its ingredients. Water is a simple compound, composed of hydrogen and oxygen, with no calories, sugar, or additives. It is the gold standard for hydration, essential for every bodily function. Mountain Dew, by contrast, is a complex beverage with a lengthy ingredient list that fundamentally changes its role in hydration.
The Impact of High Sugar Content
A single 20-ounce bottle of Mountain Dew contains a staggering 77 grams of sugar, almost 20 teaspoons. This high concentration of high-fructose corn syrup has several adverse effects on the body. While the water content of the soda provides some initial fluid, the metabolic processes triggered by the sugar can counteract true hydration. High sugar intake leads to increased calorie consumption, potential weight gain, insulin resistance, and a significantly higher risk of type 2 diabetes. Over time, this can lead to 'Mountain Dew mouth,' a term used by dentists to describe the rapid tooth decay caused by the soda's sugar and acidity.
The Role of Caffeine
Mountain Dew contains caffeine, a stimulant that is also a mild diuretic. A diuretic increases the production of urine, potentially causing a mild increase in fluid loss. While studies show that moderate caffeine intake (up to about 4 cups of coffee or its equivalent) does not significantly impact hydration in regular consumers, excessive amounts can certainly cause an increase in fluid excretion. This means that while a single can won't cause severe dehydration, relying on Mountain Dew for fluid intake could make proper hydration more difficult, especially during physical activity.
The Problem with Zero Nutritional Value
Beyond the water content, Mountain Dew offers no nutritional benefits. It provides empty calories and lacks essential vitamins, minerals, and electrolytes that the body needs. Conversely, plain water is calorie-free and helps transport nutrients to cells, regulate body temperature, cushion joints, and flush out waste. Drinking only Mountain Dew would mean missing out on these vital functions, leading to long-term health problems. Replacing water with sugary drinks like Mountain Dew has been linked to increased inflammation and a higher risk of diseases like heart disease.

| Caffeine | ~36mg (per cup) | 0mg |
| Hydration Effect | Net fluid gain, but compromised by sugar/caffeine | Optimal, pure hydration |
| Nutritional Value | None; empty calories | Essential for all bodily functions |
| Dental Health | High risk of enamel erosion and cavities | Protects teeth; no adverse effect |
Practical Hydration Strategy
For effective hydration, the key is to prioritize water. While other beverages like milk, juice, and even moderate amounts of coffee and tea can contribute to your daily fluid intake, they should not replace plain water. A simple and effective strategy is to keep a reusable water bottle handy throughout the day to sip from regularly. If you find plain water unappealing, try adding natural flavors like lemon, lime, or cucumber. Incorporating water-rich foods such as fruits and vegetables into your diet can also help meet your fluid needs. By making small, conscious changes, you can ensure your body gets the pure, clean hydration it needs without the negative baggage of excessive sugar and additives. For intense exercise lasting over an hour, a sports drink might be beneficial to replace electrolytes, but for most people, water is all that is necessary.
Conclusion: The Final Verdict
While Mountain Dew is predominantly water by volume, its high sugar and caffeine content mean it is not a suitable substitute for plain water. Counting it as water in your daily fluid intake is misleading and can lead to significant negative health consequences, including weight gain, dental problems, and an increased risk of serious diseases. The mild hydrating effect from its water content is far outweighed by the empty calories and other detrimental ingredients. For true, healthy hydration, water is and will always be the best choice.
The Health Difference: A Closer Look
Choosing water over Mountain Dew isn't just about avoiding a sugary drink; it's about choosing optimal health. The body doesn't just need fluid; it needs clean, pure fluid for waste removal, temperature regulation, and proper organ function. The added sugars in Mountain Dew can cause inflammation and disrupt the body's natural balance. This can have systemic effects, impacting everything from your energy levels and mood to the health of your kidneys and heart. Relying on caffeinated sugary drinks can also create a dependence cycle, where you feel you need the 'boost' but are ultimately left with a crash. This is a stark contrast to the sustained energy and clarity that comes from being properly hydrated with water.
The Downside of Artificial Sweeteners
Even diet versions of Mountain Dew, which replace sugar with artificial sweeteners, are not equivalent to water. Research has suggested that artificial sweeteners can increase cravings for other unhealthy foods, and some studies have linked diet soda to a higher risk of certain health issues. While they are calorie-free, they do not offer the same nutritional benefits or pure hydration as water and can perpetuate a preference for sweet-tasting drinks, making it harder to appreciate plain water. This is why transitioning away from soda entirely and embracing water, perhaps with natural flavorings, is the most beneficial approach for long-term health.
The Economic and Environmental Cost
Beyond personal health, there are other considerations. Bottled Mountain Dew contributes to plastic waste, while tap water is often free and environmentally friendly. The cost of purchasing sugary sodas over time adds up significantly, whereas choosing water is a cost-effective and healthy habit. This perspective reinforces that prioritizing water is a better choice for your wallet and the planet, in addition to your body. Making a simple switch can have a cascading positive effect on various aspects of your life. https://www.cdc.gov/healthy-weight-growth/water-healthy-drinks/index.html
The Best Way to Hydrate
Ultimately, hydration is not about what you can get away with, but what provides your body with the most benefit. While Mountain Dew contains water, it is fundamentally a sugary beverage designed for taste, not health. The healthiest and most effective way to hydrate is by drinking plain water consistently throughout the day. It supports all bodily functions, carries no negative health risks, and is the essential foundation for a healthy lifestyle.
Is it ever okay to drink soda?
Enjoying a Mountain Dew occasionally will not ruin your health. The key is moderation. It should be treated as a treat, not a primary source of hydration. An occasional sugary drink is very different from regularly substituting water with soda. As part of a balanced diet and active lifestyle, an infrequent soda is fine, but it is not a component of a healthy hydration strategy. The focus should always be on getting the majority of your fluids from pure water.
What about athletes?
For athletes engaged in prolonged, intense activity for more than an hour, consuming a sports drink with electrolytes and some carbohydrates can be beneficial for rehydration and replenishing energy stores. However, this is specific to high-intensity, long-duration exercise. For general exercise, water is still the best option. Sports drinks, like soda, often contain added sugars and should not be consumed in place of water for typical, day-to-day hydration needs.
How to tell if you are hydrated enough?
A simple way to check your hydration level is by monitoring your urine color. Pale yellow or clear urine is a good indicator of proper hydration, while dark yellow urine can be a sign of dehydration. Additionally, paying attention to thirst signals is important. While it's best not to wait until you are extremely thirsty, it is a clear sign that your body needs fluids.
What are some signs of dehydration?
Early signs of dehydration include thirst, a dry mouth, and fatigue. More severe symptoms can include dark-colored urine, dizziness, confusion, and a rapid heartbeat. It's important to address these signs promptly by increasing your fluid intake, preferably with water.
Can drinking Mountain Dew cause weight gain?
Yes. Due to its high sugar and calorie content, drinking Mountain Dew regularly can contribute to weight gain. The body digests the added sugars quickly, which can lead to increased hunger and overall calorie intake throughout the day. Replacing sugary beverages with water is a simple way to reduce calorie intake.
Is Diet Mountain Dew a healthier option?
Diet Mountain Dew is calorie-free, but it is not a healthy substitute for water. It contains artificial sweeteners and other additives that offer no nutritional value and may have other health implications. Furthermore, choosing diet sodas can maintain a preference for sweet flavors, making it harder to transition to healthier beverage options.
How much water should I drink daily?
Fluid needs vary based on age, gender, activity level, and health. The U.S. National Academies of Sciences, Engineering, and Medicine suggests an adequate daily fluid intake of about 15.5 cups (3.7 liters) for men and 11.5 cups (2.7 liters) for women, which includes fluids from all beverages and foods. For most, a good rule is to drink water and other fluids when thirsty and aim for at least four to six cups of plain water daily.
What is Mountain Dew mouth?
'Mountain Dew mouth' is a term used by dentists to describe the severe tooth decay that can result from excessive consumption of Mountain Dew, caused by its high sugar and acidic content eroding tooth enamel. Dentists note that the damage can be extensive and happens at an accelerated rate compared to other sodas.
Can you survive on Mountain Dew instead of water?
While technically containing water, a person cannot survive healthily on Mountain Dew alone. The high sugar content, caffeine, and lack of essential nutrients would lead to severe health problems over time, including dehydration, weight gain, and dental issues. Water is essential for survival and proper bodily function, whereas soda is not.
