Coffee is the most popular hot beverage. But many make a critical mistake when they pour themselves that first cup of the caffeinated beverage early in the morning. We explain the risks of drinking coffee to you.
Coffee before breakfast: Even one cup has negative effects
In an experiment, researchers from the University of Bath examined the blood sugar regulation of a total of 29 healthy men and women. To do this, they ran through different scenarios on three consecutive nights to find out whether the coffee that is drunk before the first meal is negative
During the investigations, in which the test subjects had one night of normal sleep and were awakened every hour on two nights, the test subjects’ blood sugar levels were continuously measured. The scientists realized that just one cup of coffee with about 300 milligrams of caffeine is enough to produce an increase in blood sugar.
The increase is particularly strong after the restless nights.
Conclusion: Coffee should only be drunk after breakfast
Although a high blood sugar level is not initially a serious symptom of the disease, if it rises regularly, it can lead to type 2 diabetes mellitus, according to the researchers.
A high blood sugar level caused by drinking coffee in the morning can be avoided if the hot drink is only drunk after breakfast. So far, five cups of the caffeinated beverage have been considered safe, provided they are not drunk too hot, on an empty stomach, or after too short a night’s sleep.
