M/R – Does caffeine count?

Myth or Reality?

Caffeinated beverages (e.g., tea and coffee) count towards your 8 glasses of water per day?

We’ve heard countless times that we should drink 8 glasses of water per day – 8 oz each, to be specific. Although this 8×8 rule doesn’t rhyme true for everyone (required intakes vary based on health, where we live and our level of physical activity), drinking just under 2 liters of liquids per day will certainly help most of us replenish our normal fluid losses. The most recent version of the Dietary Reference Intakes by the Institute of Medicine (2006) states that “…caffeinated beverages appear to contribute to total water intake to the same degree as noncaffeinated fluids do”.

So there you have it, your daily cup of coffee does count to keep you hydrated!  To learn more about caffeine and the amounts that are considered safe, navigate to Food Sources of Caffeine by Dietitians of Canada.
