Maughan RJ, Watson P
Published in American Journal of Clinical Nutrition
Methodology
Randomized crossover trial in healthy men comparing net fluid balance after ingesting 13 common beverages.
Key Findings
Beverages containing electrolytes and/or macronutrients produced greater fluid retention at 2-4 h than plain water.
Conclusions
Electrolyte content is a key determinant of how well a beverage sustains hydration.
Limitations
Healthy euhydrated young men only; short observation window.
Outcomes Measured
A randomized trial to assess the potential of different beverages to affect hydration status: development of a beverage hydration index
Beverages containing electrolytes and/or macronutrients produced greater fluid retention at 2-4 h than plain water.
