Diuretic coffee myths
One study investigated the effects of six cups of coffee mg caffeine on urine excretion following a five day caffeine deprivation period . These active compounds may interact with each other and therefore coffee consumption cannot be directly compared to caffeine consumption in its purest form 1,3,7-trimethyl xanthine . Total body water TBW estimations using the doubly labelled water dilution technique is considered the gold standard method for assessing body water fluctuations over time . Means and standard deviations of haematological measures recorded on trial days 1, 2 and 3 are presented in table 5. No differences in TBW were observed between the caffeine and placebo control group. Received Aug 14; Accepted Nov Although there are widespread guidelines in scientific literature and media for achieving optimal hydration status and about the effects that various caffeinated beverages may have on fluid balance, there is no clear consensus about how much fluid an individual should consume . Figure 2 illustrates the results of TBW estimates, based on deuterium oxide analysis performed by gas chromatography mass spectrometry.

It may have been interesting to include a decaffeinated coffee condition as this would have identified any differences specifically caused by caffeine in coffee and not any of the other bioactive components, however as we found minimal differences between coffee and water we believe that it is unlikely that we would have found any significant differences if we had included a decaffeinated coffee condition.
The aim of this study was to directly compare the effects of coffee The diuretic potential of caffeine in humans has been researched for many. "It's well understood that if you drink coffee habitually you can develop a tolerance to the potential diuretic effects of coffee," says study author.
It's calorie-free, caffeine-free, inexpensive and readily available. These findings support participant compliance to the diet and test beverage during each trial.
A compliance booklet was completed by participants on the morning of each trial day to ensure all food and beverages from the previous day were consumed at the correct times and that no unplanned exertions, fluid losses or nutritional variations had occurred.
