Drinking coffee before breakfast could be bad for you, according to a new report. Researchers are warning that a strong black coffee after a bad night of sleep could impair control of blood sugar levels.
But experts say the best way to avoid the problem is to eat first - and then drink coffee if you feel you still need it. Researchers from the University of Bath examined the effect of broken sleep and morning coffee across a range of metabolic markets, the Express reports.
Their work, published in the British Journal of Nutrition, revealed that one night of poor sleep had a limited impact on metabolism, but drinking coffee could have a negative effect on blood glucose control. Professor James Betts, co-director of the Centre for Nutrition, Exercise and Metabolism at the University of Bath, said: "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.
