However, there are studies that affirm that this is not the case since they alter the metabolism of sugar producing what is known as glucose intolerance or insulin resistance and imbalances in the intestinal flora.
In a study conducted at the Weizmann Institute and Tel Aviv University, a group of mice was given water containing three mass-use sweeteners and compared the results with the metabolic response of others who drank plain water or sugar water and verified that those in the first group had developed glucose intolerance in the eleventh week.
They then collected information among human beings and questioned 381 non-diabetic volunteers about their consumption of artificial sweeteners, which allowed them to verify that the forty participants who had consumed the most had higher blood sugar levels in relation to the 236 who had not. they had been consumed.
Seven healthy volunteers who normally did not consume sweeteners were then given saccharin for a week, and after that week four of them showed changes in the distribution of their gut bacteria and a decrease in their ability to process sugar. The research director, Dr. Eran Elinav, from the Department of Immunology at the Weizmann Institute, together with Professor Eran Segal, from the Department of Applied Mathematics and Informatics, affirm that the widespread use of artificial sweeteners in beverages and food can contribute to obesity and the diabetes epidemic that is affecting much of the world.
It is important to understand what the graduate student Jotam Suez argues in Elinav's laboratory, in charge of the research, about the discovery that artificial sweeteners, despite not containing sugar, have a direct effect on the capacity of the body to use glucose.
Other human studies have verified that artificially sweetened beverages are associated not only with obesity, type 2 diabetes, and metabolic syndrome, but also with cardiovascular disease from just one drink a day.
People who regularly consume artificial sweeteners have been found to have altered activation patterns in the brain's pleasure centers in response to sweet taste, indicating that these synthetic chemicals are unable to satisfy the craving for sweets.
These studies suggest that encouraging people to drink diet sodas could backfire as a public health message. So the current public health message of limiting sugar intake has to be expanded to reduce consumption of all sweeteners and not just sugars, "warns Susan E. Swithers, from Purdue University in Indiana (United States). ) in an article published in the journal Trends in Endocrinology and Metabolism.
