When people take large amounts of artificial sweeteners, the risk of type 2 diabetes increases
There have been discussions for a long time about what artificial sweeteners trigger in our body. Researchers have now found that consuming large amounts of artificial sweeteners can change the body's response to glucose. This increases the risk of developing type 2 diabetes for consumers.
The researchers at Adelaide Medical School at the University of Adelaide found that increased intake of artificial sweeteners can contribute to the development of type 2 diabetes. The experts published the results of their study at this year's meeting of the European Association for the Study of Diabetes (EASD) in Portugal.
Does taking artificial sweeteners lead to type 2 diabetes?
Earlier studies have already shown that the consumption of large amounts of artificial sweeteners is associated with an increased risk of developing type 2 diabetes, the doctors explain. The underlying mechanisms are still unknown. That is why the new study by the scientists at Adelaide Medical School aimed to investigate more closely the effects of the consumption of large amounts of artificial sweeteners on the human body.
Subjects took large amounts of artificial sweeteners for two weeks
The doctors recruited 27 healthy volunteers for their examination. These were given two different artificial sweeteners (sucralose and acesulfame-K). The amount was equal to the intake amount when drinking 1.5 liters of a sweetener drink. Some subjects received only an inactive placebo as a control. The sweeteners were administered in the form of capsules, which were taken three times a day before meals over a period of two weeks, the scientists explain. At the end of these two weeks, the response to glucose was then examined in the test subjects. The experts added that the plasma glucose and insulin values, the intestinal peptides and the glucose absorption were examined, according to EurekAlert.
How did the intake of high amounts of artificial sweeteners work?
The research team found in their investigation that the intake of artificial sweeteners leads to an increase in responses to glucose. Both the absorption of glucose and the blood sugar levels of the affected subjects were increased. In addition, the intestinal peptide GLP-1 was reduced, which affects the increase in blood sugar after meals. If the subjects only took a placebo, the values did not change, the doctors say.
Artificial sweeteners can reduce the body's own control of blood sugar levels
The scientists also found that just taking artificial sweeteners over a two-week period is enough to increase glucose absorption. The authors conclude that artificial sweeteners can affect the body's control of blood sugar levels. The increased glucose level in users of artificial sweeteners after a meal could, in turn, pose an increased risk of developing type 2 diabetes. (as)
