dehydration

New research from the University of Birmingham, UK, published on Thursday, in the scientific journal "PLoS ONE", shows that there is no relationship between moderate coffee consumption and dehydration.
This study began because of a previous research that showed the acute effects of caffeine as a mild diuretic, and a common assumption that caffeinated drinks such as coffee, had this effect. However, the effect of coffee consumption in fluid balance cannot be compared directly with that of pure caffeine.
