From Bath.ac.uk……..
A strong, black coffee to wake you up after a bad night’s sleep could impair control of blood sugar levels, according to a new study.
Research from the Centre for Nutrition, Exercise & Metabolism at the University of Bath (UK) looked at the effect of broken sleep and morning coffee across a range of different metabolic markers.
Writing in the British Journal of Nutrition the scientists 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.
