No evidence of dehydration with moderate daily coffee intake: a counterbalanced cross-over study in a free-living population

What this work gives Aellic

Fifty male habitual coffee drinkers, counterbalanced cross-over over three days: 4 x 200 ml of coffee providing 4 mg/kg caffeine per day against the same volume of water. No difference in total body water, in any haematological marker, or in 24 h urine volume. The authors conclude that coffee in moderation provides similar hydrating qualities to water. Carries the decision to count coffee and tea at a factor of 1.0 instead of the 0.85 that fitness apps commonly apply without a source.
