I’ve Been Giving Legs To This Misguided Science For Years.

Is Coffee Really Dehydrating?

Breakfast is the most important meal of the day.  Is it?  Or, have we just heard the phrase enough to believe it’s true?  I used to tell people (with utter conviction) that they should never skip breakfast.  Then I looked for the science, and it turns out that our morning meal has become a scientific war zone!  The more studies you read, the more confused it becomes.  So for the last few years I gave up breakfast.  It began as an experiment, and now I just prefer it.  I workout in the morning, and often run 5-10km before I eat anything – no problem.  So skipping breakfast turns out to be no big deal.  So now I must confess to another bit of science-lore that I have often quoted that I want to come clean on.

If you have ever heard me say that “coffee is dehydrating”, then I apologize, it’s hogwash, garbage, totally untrue.  As it turns out, even a moderate intake of coffee each day will not produce dehydration. 

The study looked at two groups one drinking water, the other caffeinated coffee. The researchers controlled the participants’ activity, food, fluid and coffee intake during the study.

The researchers then measured the groups hydration status. They concluded “there were no significant differences across a wide range of hematological and urinary markers of hydration status between trials.”

So if you enjoy a cup of coffee in the morning, please disregard any bad advise I may have given regarding dehydration.

Sorry Joe!
