This leads to high blood sugar levels which can lead to diseases like diabetes or heart problems over the years.
Starting the day with a good hot coffee is a ritual for millions of people around the world, for some it is a fundamental moment to start the day. If we don’t have time for coffee in the morning, the day starts badly, but is it really a good habit? According to recent research, regular coffee consumption early in the morning can lead to type 2 diabetes in the long term.
Coffee raises blood sugar levels
This study was conducted by a team of researchers from the University of Bath, who asked 29 volunteers to drink a cup of strong black coffee an hour after waking up, then testing their blood sugar levels after breakfast. Data analysis showed that drinking sweetened coffee, which contains the same calories as bread and jam, raises blood sugar levels by approximately 50% compared to the absence of coffee.
According to the researchers, caffeine would prevent the muscles from absorbing sugar. This leads to high blood sugar levels, which can lead to diseases like diabetes or heart problems over the years. As Professor James Betts, the lead author of the study, explains, this does not mean that we should give up coffee, a drink that also brings many benefits, but simply that we should wait a little longer after our wake up to enjoy our beloved cup of coffee.
In fact, it would be better to have no caffeine in your blood when eating a breakfast full of carbohydrates and sugar . We could, for example, drink coffee when we start working or going about our daily activities.
Does not affect the quality of sleep
The study also tested the effects of coffee on people who are sleepless or have disturbed nighttime rest. For this research, volunteers were asked to set an alarm clock every hour during the night. At each alarm, to make sure it was not ignored, the researchers sent messages every 30 seconds, with simple sums to which the volunteers had to answer.
Then, in the morning, glucose and insulin levels were measured under three different conditions: after a sleepless night and without coffee, after having slept, without coffee and after having a disturbed sleep and with a cup of coffee in the morning. In the latter case, the measurement was taken 30 minutes after drinking a cup of strong black coffee.
L Data analysis showed that coffee and disturbed sleep in the evening did not alter insulin levels. While coffee drunk before breakfast significantly increases blood sugar levels. This increase in blood sugar levels was demonstrated by a blood glucose test every two hours for volunteers who had drunk coffee in the morning, just before breakfast.
According to Professor Betts , “this study is important and has far-reaching implications for health because until now, we had only limited knowledge about the causes of coffee in our bodies, especially for the control of metabolism and blood sugar” .
