How much coffee do you drink?

After a glass of water, the first thing to touch my lips every morning is coffee. And I am not alone it seems, New Zealand's consumption ranks top 20 in the world - but new research suggests we may only need one cup a day?

A flat white, with trim milk, is my morning coffee order. And after that first cup, the world does feel like a much better place. It's the way most of us start the day. However, a new study from the American academy of sleep medicine has revealed after three consecutive nights of less than five hours of sleep, an extra cup of coffee has zero effect of giving you an extra energy boost. Researchers found that beyond one cup of coffee (that's is a small flat white or 200 milligrammes of caffeine), there was no "measurable effect," in helping give you that feeling of getup and go. However, if we flip this research on its head, the great news is that one cup helps; and you don't need that second cup. "The data from this study suggests that the same effective daily dose of caffeine is not sufficient to prevent performance decline over multiple days of restricted sleep," said Tracy Jill Doty, Ph.D., the study's lead author.
So what should you drink to help promote energy? Water is the key. It will kick start your metabolism and make you feel so much better. Often it's dehydration that makes you feel tired and sluggish. So for a healthy start - after a green smoothie, chug down a couple of glasses of water, one coffee, and you will feel ready to start your day.
