The Science of Hydration and Beverages
All beverages containing water contribute to daily hydration. Plain water is the standard, but other drinks also meet the body's needs. Drinks like oat milk contain electrolytes, carbohydrates, and fats. These elements affect how the body absorbs and retains fluid. Oat milk contributes fluid but adds calories and other components.
Oat Milk's High Water Content
Oat milk is a blend of oats and water. This process results in a liquid that is mostly water. According to the USDA, oat milk is about 90-91% water. This confirms that oat milk adds fluid to your system, helping you meet hydration targets.
Oat Milk vs. Water: Nutritional Differences
It's important to differentiate oat milk's contribution from that of pure water. The following table highlights the key nutritional differences.
| Feature | Oat Milk (Unsweetened) | Plain Water |
|---|---|---|
| Primary Composition | Water, Oats, Vitamins, Minerals | Pure Water |
| Hydration Value | High (around 90% water) | Highest (100% water) |
| Calories (per cup) | ~90-120 kcal | 0 kcal |
| Electrolytes | Added for fortification (e.g., Calcium, Potassium) | None |
| Carbohydrates | Contains carbs from oats | None |
| Added Sugars | Varies by brand (often 0-7g in unsweetened) | None |
| Fiber | Contains fiber from oats | None |
Fortification and Nutrients
Most oat milk is fortified to match the nutritional profile of cow's milk. This means nutrients like calcium, vitamin D, and B12 are added. The electrolytes play a role in fluid balance. However, the presence of carbohydrates and calories means that drinking large quantities of oat milk can impact overall energy intake, unlike plain water. A single cup of unsweetened oat milk has 90-120 calories.
Counting Oat Milk Towards Fluid Goals
Oat milk can be counted towards daily fluid intake. The average healthy adult needs about 8-13 cups of fluid per day. Oat milk is a supplementary, nutrient-rich fluid, not a replacement for water. It's important to monitor sugar content in flavored varieties.
Practical Hydration Tips
- Prioritize Water: Make plain water your main fluid source.
- Use Oat Milk Strategically: Use oat milk where its nutrients and calories are beneficial.
- Mind the Calories: Be mindful of oat milk consumption.
- Check for Added Sugar: Choose unsweetened oat milk to limit sugar.
- Incorporate in Recipes: Use oat milk in smoothies and other recipes.
Hydration in Context: When Oat Milk Is a Good Choice
- Dairy-Free Alternative: For those with lactose intolerance, oat milk is an option.
- Nutrient Boost: Fortifications provide vitamins and minerals.
- Flavor and Variety: Oat milk can help increase overall fluid intake.
Conclusion: A Balanced Approach to Fluid Intake
Oat milk counts towards daily fluid intake because it is mostly water. It is different from plain water due to its caloric and nutritional content. The best approach to hydration is balanced and prioritizes water while including other hydrating beverages like oat milk strategically. Consult a healthcare professional for dietary advice.
Frequently Asked Questions
Can I use oat milk instead of water to hydrate after a workout?
Water is more efficient for quick hydration. Oat milk can provide carbohydrates and electrolytes for recovery.

Excessive consumption could lead to unhealthy intake of calories and sugars. Moderate consumption is recommended.
Is oat milk suitable for everyone seeking hydration?
Oat milk is suitable for most people. Those with conditions like diabetes should consult a doctor.
How does oat milk's water content compare to cow's milk?
Oat milk and skim cow's milk have similar water percentages.
Should I worry about the water used to make oat milk?
Oat milk production generally uses less water than dairy milk production.
