Breakfast increases blood sugar

Why You Shouldn't Have Coffee Before Breakfast!

Why You Shouldn't Have Coffee Before Breakfast!

In the morning after getting up, a cup of coffee is simply part of waking up - especially if the sleep of the previous night was rather modest. But according to a study, this combination of sleep disorders and coffee is said to have adverse effects on blood sugar.

Researchers at the University of Bath, UK, have investigated the connection between sleep disorders and certain metabolic markers, including blood sugar. They found out that insomnia alone has no effect on blood sugar. It was only the combination of insomnia and coffee before breakfast that caused the blood sugar to rise. The subjects who drank their coffee before breakfast had increased their blood sugar levels by 50 percent.

This is how the investigation went

30 healthy female and male test subjects took part in the study and were asked to perform the same tasks one after the other:
  1. During the first task, the test subjects were allowed to sleep in. In the morning you should have a high-sugar, high-calorie drink that is close to the calorie density of a regular breakfast.
  2. In the second part, the subjects were woken up once an hour at night and kept awake for five minutes. After the night, the participants received the same drink as in the first task.
  3. In the last part, the subjects were woken up once an hour and kept awake for five minutes. The morning after, however, the participants first drank a black coffee, waited 30 minutes and only then had their breakfast drink.

Results remain questionable for the time being

The researchers believe that blood sugar increased because the caffeine reduces the body's ability to metabolize the sugar in the breakfast drink. However, the results only relate to a manageable number of participants, so that the informative value remains questionable. Nevertheless, the study could give cause for further studies and hints for z. B. Type 1 and Type 2 diabetics.
Nevertheless, scientists and doctors see a permanently high blood sugar level as a risk of developing diseases such as cardiovascular diseases, obesity or diabetes.
