Drinking coffee before breakfast can make you suffer from diabetes: experts warn that drinking caffeine in the morning can raise blood sugar by 50%
- Drinking coffee regularly before breakfast may increase the risk of type 2 diabetes
- Researchers at the University of Bath let volunteers wake up to drink coffee
- Found that their blood sugar was 50% higher than without coffee
- The British Journal of Nutrition says that frequent blood sugar rises may lead to diabetes
For millions of us, it is not worth starting a new day without coffee.
But experts warn that it is best not to drink caffeine before breakfast, because drinking coffee regularly for a long time may increase the long-term risk of developing type 2 diabetes.
Researchers at the University of Bath asked 29 volunteers to drink a cup of strong black coffee about an hour after getting up to understand how this affects their blood sugar after breakfast.
Then after drinking a sugary drink (calorie content similar to cereal or jam bread), their blood sugar was about 50% higher than without coffee. The caffeine in beverages is thought to prevent the muscles from absorbing sugar.
Experts warn that it is best not to drink caffeine until after breakfast, because drinking coffee regularly for a long time may increase the long-term risk of type 2 diabetes
Research in the British Journal of Nutrition suggests that this may not be an immediate problem, but the frequent rise of blood sugar over the years can lead to diabetes and heart disease.
Professor James Betts, the senior author of the study, said: “Nearly half of people wake up in the morning and drink coffee before doing other things-intuitively speaking, the more tired we are, the stronger the coffee will be. .
“I also love coffee. I don’t have to tell people not to drink coffee because it has some benefits.
“Maybe people should wait a while, or wait until they go to work, so that when they eat a breakfast with carbohydrates and sugar, there will be no caffeine in their system.”
It is believed that about 40% of people in the UK drink coffee as soon as they wake up.
Researchers want to see its impact on people who are not sleeping, so they asked study participants to set the alarm to sound once every hour at night.
Researchers at the University of Bath asked volunteers to drink a cup of strong black coffee about an hour after getting up, and found that their blood sugar was about 50% higher than without coffee.
When they woke up, to make sure they would not fall asleep, the researchers sent them some questions, such as sending a simple sum every 30 seconds, and then they had to answer.
The study looked at people’s blood sugar and insulin levels in three stages-sleep all night without coffee at home, sleepless in bed without coffee, and after a break without coffee.
This is 300 mg of strong black coffee-roughly equivalent to two standard cups.
After drinking coffee after breakfast, participants took a blood sugar test about 30 minutes after drinking coffee.
The study was published in the British Journal of Nutrition and found no effect on insulin levels from coffee or lack of sleep.
However, consuming strong black coffee before breakfast greatly improved the blood sugar response, as shown by repeated blood tests for more than two hours.
Professor Bates said: “This research is very important and has a profound impact on health, because so far, we have very limited understanding of the effects of coffee on the body, especially metabolism and blood sugar control.”
