What Can You Mix Rehydrate With? The Definitive Guide to Safe & Tasty Hydration

6 min read

According to the Centers for Disease Control and Prevention (CDC), oral rehydration therapy (ORT) is a simple, effective, and low-cost treatment for dehydration caused by diarrhea. Many people, however, find the taste of standard ORS packets unpalatable, leading them to seek creative mixing solutions.

Quick Summary

This guide provides a detailed look at appropriate liquids for mixing rehydration solutions, detailing which options are safe and which can interfere with the electrolyte balance. It also offers specific instructions and recipes for improving taste, especially for children.

Key Points

  • Water is the only recommended mixer: For commercial oral rehydration salts, only use the amount of clean, fresh water specified on the package.

  • Flavor with caution: Use very small, measured amounts of unsweetened juice or sugar-free flavorings if necessary, but water is safest.

  • Avoid high-sugar drinks: Sodas, undiluted juices, and sports drinks can worsen diarrhea due to their high sugar content.

  • Do not add extra sugar or salt: Commercial ORS has a precise electrolyte-to-sugar ratio that must be maintained for effectiveness.

  • Chill or freeze for better taste: Serving the solution cold or as ice pops can make it more palatable, especially for children.

  • Consult a professional for severe cases: Homemade solutions are not a substitute for commercially prepared ORS in cases of severe dehydration, and professional medical advice should be sought.

The Essentials of Proper Rehydration

Rehydration is the process of restoring lost fluids and electrolytes in the body. While plain water is excellent for daily hydration, situations involving significant fluid loss, such as persistent diarrhea, vomiting, or intense exercise, require a more balanced solution. Oral rehydration salts (ORS) are specifically formulated to provide the correct ratio of sugar and electrolytes (primarily sodium and potassium) to facilitate rapid absorption by the intestines. Altering this precise balance can make the solution less effective and potentially harmful, particularly in vulnerable groups like infants and young children.

The Golden Rule: Water is King

When using commercial rehydration salts (sachets or tablets), the most critical instruction is to mix them with the specified amount of clean, fresh drinking water. For infants, it is recommended to use boiled and cooled water to ensure safety. Following the package directions precisely is non-negotiable for ensuring the correct electrolyte concentration. Never assume that 'more powder is better' or that adding extra salt or sugar is a good idea, as this can worsen the condition. The best and safest answer for what can you mix rehydrate with is always water.

Safe Alternatives for Flavoring

While water is the base, adding small, specific flavorings can make the solution more palatable, especially for those who dislike the salty taste. The key is moderation and using ingredients that won't disrupt the critical electrolyte balance.

  • Small amounts of diluted, unsweetened juice: A study found that adding small quantities of unsweetened juice, like apple or orange, can improve taste without significantly altering the composition. It is crucial to use very small amounts and ensure the juice is unsweetened to prevent adding excessive sugar.
  • Unsweetened flavor powders: Small amounts of unsweetened flavor powders, like sugar-free squash concentrate, can be mixed in to enhance taste without compromising the formula.
  • Lemon or lime juice: A squeeze of fresh citrus can significantly improve the taste and provides a pleasant, tangy flavor.
  • Chilling the solution: Simply chilling the prepared rehydration solution in the refrigerator can make it much more pleasant to drink.
  • Rehydration ice blocks: Freezing the rehydration solution into ice cube trays or popsicles is an excellent strategy for children or for soothing a sore throat.

What to Avoid Mixing with Rehydration Salts

Not all liquids are created equal, and some can actively interfere with the rehydration process. To ensure maximum efficacy and prevent complications, avoid mixing rehydration salts with the following:

  • Sugary drinks: Undiluted fruit juices, sodas, and sports drinks contain too much sugar, which can draw water into the intestines and worsen diarrhea.
  • Milk or formula: Do not mix ORS with milk or formula. Infants should continue breastfeeding or receiving their formula separately from the ORS, as directed by a healthcare professional.
  • Caffeinated beverages: Coffee, tea, and energy drinks are diuretics and can worsen dehydration.
  • Alcohol: Alcohol is a known dehydrator and should be completely avoided.
  • Extra sugar or salt: Adding more sugar or salt to a commercial ORS packet disrupts the careful balance of electrolytes and can be counterproductive.

Comparison of Rehydration Mixers

Mixer Type Safety for ORS Best For What to Watch For
Water Excellent (Required) Mixing commercial ORS sachets Always use clean water; boil and cool for infants
Small Amounts of Diluted, Unsweetened Juice Generally Safe (with caution) Improving palatability for children; use very little to avoid excessive sugar Disrupting electrolyte balance if too much is added
Unsweetened Flavor Powders Generally Safe (with caution) Flavoring ORS for those who dislike the taste; choose sugar-free versions Hidden ingredients or artificial additives; read labels carefully
Coconut Water Not Recommended for ORS Standalone natural rehydrator; can be a homemade base with added salt Incorrect electrolyte balance if mixed with commercial ORS
Sugary Drinks (Sodas, Juices) Not Recommended (Harmful) None Worsening diarrhea due to high sugar content; avoid entirely
Milk/Formula Not Recommended (Harmful) Feeding separately as appropriate for age Disrupting electrolyte balance; do not mix

Homemade Electrolyte Alternatives

While pre-packaged ORS is the most reliable option for treating moderate-to-severe dehydration, especially in emergencies, some individuals opt for homemade alternatives. A common, simple recipe involves a liter of water, a half teaspoon of salt, and two tablespoons of sugar. Other recipes use coconut water as a base, leveraging its natural potassium content, but require careful balancing with added salt. It is crucial to remember that homemade solutions are not a replacement for commercially prepared, WHO-standardized ORS, particularly for treating severe dehydration or in children. Always consult a healthcare provider for the most effective treatment plan.

For more detailed information on homemade electrolyte solutions, resources like Marathon Handbook offer various recipes, but it's important to understand they are intended for general hydration or exercise, not as a replacement for medical ORS.

Conclusion

While plain, clean water is the standard and safest mixer for oral rehydration salts, there are a few careful and safe ways to make the solution more appealing. For commercial ORS packets, stick to water and, if necessary, add a small, measured amount of unsweetened flavoring. Avoid high-sugar, caffeinated, or dairy-based beverages, as they can interfere with the therapeutic balance of the solution. Ultimately, the priority is to maintain the precise electrolyte composition to ensure effective and safe rehydration, especially when dealing with illness.

Key Takeaways

  • Mix ORS with water only: Always follow the package instructions and mix rehydration salts with the precise amount of clean, fresh water.
  • Flavor safely with moderation: Use minimal amounts of diluted, unsweetened juice, sugar-free flavor concentrate, or a squeeze of fresh lemon to improve taste.
  • Avoid high-sugar liquids: Steer clear of soda, undiluted juices, and sports drinks, as their high sugar content can worsen diarrhea and hinder rehydration.
  • Do not mix with milk or formula: Dairy products should not be mixed with ORS. Continue breastfeeding or formula-feeding infants separately as advised.
  • Freeze for a tasty treat: Make rehydration popsicles or ice cubes for children to make the process more enjoyable.
  • Prioritize commercial ORS: Rely on commercially available ORS for treating moderate to severe dehydration due to their proven, balanced formulation.
  • Use caution with homemade recipes: Homemade electrolyte drinks should not replace commercial ORS for treating illness, though they can be useful for general hydration.
