Wait until after breakfast to drink coffee, study says

You may want to clear your morning schedule if you can’t get your day started without a cup of joe.

A new study recommends waiting until after you eat breakfast to have your first cup of coffee, especially if you had a night of choppy sleep, CNN reports.

The study, conducted by the University of Bath in the UK, finds that having coffee first thing in the morning can have a poor effect on blood sugar control, which is a risk factor for diabetes and heart disease.

"We know that nearly half of us will wake in the morning and, before doing anything else, drink coffee -- intuitively the more tired we feel, the stronger the coffee," Professor James Betts, professor and co-director of the university’s Centre for Nutrition, Exercise and Metabolism, said in a press statement.

Betts added that before this research, experts “had limited knowledge about what this is doing to our bodies, in particular for our metabolic and blood sugar control.”

The study assessed 29 men and women who participated in three separate overnight experiments, conducted at intervals of at least one week.

The three experiments analyzed the participants’ blood sugar levels after a night’s sleep.

In the first, study subjects got a normal night’s sleep from 11am to 7pm and were given a sugary drink to have when they woke up.

In the second, they were given the same drink in the morning, but after a night where they had to wake up once an hour for five minutes to respond to a text.

The third night consisted of interrupted sleep similar to the second, but the participants were given coffee instead of a sugary drink upon waking up.

The study found that the blood glucose response increased by approximately 50% after a strong  cup of black coffee consumed before breakfast. The result suggests that the body may be less able to handle sugar and carbs in breakfast when a night of poor sleep is remedied with strong coffee.

Betts suggests that it is therefore not advisable to drink a strong cup of java within an hour before a carb-heavy breakfast.
