What this work gives Aellic
Thirteen beverages measured against still water as the reference. Cumulative urine output over 4 h after cola, diet cola, hot tea, iced tea, coffee, lager, orange juice, sparkling water and a sports drink was not different from water. Only an oral rehydration solution, full-fat milk and skimmed milk retained more, with a mean beverage hydration index at 2 h of 1.54, 1.50 and 1.58 respectively. This is why every non-alcoholic drink in Aellic counts in full, and why beer does too.
Correction of 12 September 2026
On its first day in the registry this entry placed orange juice among the beverages that retained more fluid than water. The abstract puts orange juice in the no-difference group; only the oral rehydration solution and the two milks beat water. The factors themselves were unaffected, since both groups count at 1.0 in Aellic.
The entry on the register was wrong. It was not replaced but kept, with what holds instead standing next to it.
