In the study, the U．K.researchers let 29 healthy men and women take part in three different overnight experiments.In the first two scenes, participants were given a sugary drink upon waking first from a normal night's sleep, and then again after a greatly disturbed night's sleep.In the third, their sleep was similar, but they were given a strong black coffee 30 minutes before having the sugary drink. Blood samples from participants were taken following the sugary drinking in each experiment.Results showed that one night of disturbed sleep did not worsen the partieipants' blood sugar responses at breakfast when compared to a normal night of sleep.However, strong black coffee consumed before breakfast increased the blood sugar response by around 50 percent. By drinking such kind of drink after breakfast, U．K.researchers found that our bodies' ability to break down our food healthily is completely improved.Examining the effects of broken sleep and morning coffee through a range of different metabolic markers, researchers found that, while one night of poor sleep had a limited effect on metabolism, drinking coffee before breakfast could have a negative effect on blood sugar control. “We know that nearly half of us will wake in the morning and, before doing anything else, drink coffee—the more tired we feel, the stronger the coffee is.This study is important and has far­reaching influences on health, and it indeed shakes some coffee drinkers.Up to now we have had limited knowledge about what this is doing to our bodies, in particular for our metabolism and blood sugar control, so we have a long way to go，” said Professor James Bette, co­director of the Centre for Nutrition at the University of Bath. 1．How did the U．K.researchers get the result of the expe
