The role of Caffeine on hydration status

The role of Caffeine on hydration status

You hear so much about caffeine and how it is beneficial for your health while also hearing how it’s a diuretic and may be harmful to you. As an avid coffee drinker I decided to look into it to see if I really needed to limit my intake to 1 cup a day. On average we are told to drink six 8 ounce glasses of water a day. What if you drink a cup of coffee or tea instead, does that count in your daily fluid intake?

 The good news is I can drink my morning coffee and afternoon tea and not worry! Caffeine does not have the horrible effect on our hydration status when taken in moderate amounts, it actually helps us sustain it. According to the National Institute of Health two to three 8 ounce cups of coffee a day is considered moderate. The research did suggest that if you are new to coffee and caffeinated beverages it may have tendencies of being a diuretic.

The biggest myth about coffee has to be that it’s a diuretic and for that reason not good for our health. However, based on research out of Connecticut University, the diuretic effect of coffee is so small and almost undetectable. A cup of coffee is 95% water before you add anything to it, so learning that almost didn’t surprise me. You do in fact drink water when drinking coffee, which means hydration.

While researching for this post I saw a lot of contradicting facts;  largely because there’s still plenty of research being done about coffee, caffeine, and it’s effect on our body. The kind of caffeine you are drinking, when you are drinking it and your overall health all play a role in how it effects you.

Some facts to remember:

Caffeine is good for endurance athletes and alertness

It does NOT increase your risk of CVD

It may effect individuals with blood pressure or blood sugar concerns

Most people drink it for taste and aroma rather than addiction
