I sometimes feel like I should be drinking more water. After all, look at all those people drinking bottled water! I usually go for coffee! Either strong black or perhaps a nice Cappuccino. I just love it, and my doctor told me at one point that it was a ok way to get hydrated, as long as it didn’t give me the jitters or cause sleep problems (it never does and I can drink regular coffee after an evening meal and have no trouble going to sleep.
New research(1), published today in the PLOS ONE, has found no evidence for a link between moderate coffee consumption and dehydration. The research, conducted by researchers at the University of Birmingham School of Sport and Exercise Sciences, UK, found that drinking moderate amounts of coffee does not result in dehydration and contributes to daily fluid requirements in regular coffee drinkers just as other fluids do.
Due to early research showing the acute effects of caffeine as a mild diuretic, there appears to be a common assumption that caffeinated beverages, such as coffee also have this effect.
