Drinking coffee before breakfast may up diabetes risk

Researchers have found that drinking coffee first thing can have a negative effect on blood sugar control — a risk factor for diabetes and heart disease.

For the study, published in the journal British Journal of Nutrition, the research team looked at the effect of broken sleep and morning coffee across a range of different metabolic markers.

“The results show that whilst one night of poor sleep has limited impact on our metabolism, drinking coffee as a way to perk you up from a slumber can have a negative effect on blood glucose (sugar) control,” said study authors from the University of Bath in the UK.
