This Is the Worst Time to Drink Your Morning Coffee, Study Says


For many people out there, there's no starting the day until you get that cup of coffee. This is especially true of those who don't always have time to sit and eat a full breakfast. But new research has found that downing your first cup of coffee before your first meal of the day is actually a big mistake. In fact, the research, which was recently published in the British Journal of Nutrition, suggests it's better to have a little something to eat before you reach for your mug for the sake of your health.

The research out of the Centre for Nutrition, Exercise & Metabolism at the University of Bath in the U.K. looked at the effects that a black cup of coffee had on 29 healthy men and women. The subjects were asked to undergo three different conditions in random order: one with a normal night's sleep followed by a sugary drink first thing in the morning, one where they were woken for five minutes every hour and given the same sugary breakfast drink, and one where sleep was interrupted but the subjects were given a cup of coffee a half an hour before the sugary drink. By taking blood samples of the participants, the researchers found that those who had coffee before their sugary beverage had a 50 percent blood glucose spike compared to the other subjects.


The researchers say that despite other studies that show specific health benefits of morning coffee, having a cup of joe before breakfast could make it harder for your body to tolerate sugar and carbohydrates commonly found in your morning meal, spiking insulin resistance. Over time, the study authors say, this could increase your risk of diabetes and heart disease.

"Put simply, our blood sugar control is impaired when the first thing our bodies come into contact with is coffee especially after a night of disrupted sleep," study co-author James Betts, PhD, co-director of the Centre for Nutrition, Exercise, and Metabolism at the University of Bath, said in a statement. "We might improve this by eating first and then drinking coffee later if we feel we still feel need it. Knowing this can have important health benefits for us all."
