Artificial sweeteners are considered harmful to the good bacteria that live in the intestine
This is according to a new study published in the journal Molecules, by researchers at Ben-Gurion University of Negev, Israel, and Nanyang Technological University in Singapore.
The research indicates a relative toxicity of six sweeteners aspartame, sucralose, saccharin, neotam, acesulfame potassium (Acesulfam K) and advantame. In addition, 10 sports supplements that have these artificial substances in the ingredient list were examined.
Although approval bodies such as EFSA provide specific recommendations for the amount of each ingestible sweetener, the study showed that it may be necessary to reassess the doses. According to the analysis, the bacteria in the digestive system identified the presence of toxic substances when exposed to concentrations of only 1 mg of these artificial sweeteners.
The researchers stated that “the bacteria act as a representative sensor in the complex microbial system, which is another proof that the consumption of artificial sweeteners adversely affects intestinal microbial activity, which can cause major health problems.”
Artificial sweeteners are used in a variety of sugary foods and soft drinks. Many people use such ingredients without knowing, or understand that artificial sweeteners are added in certain products. In addition, artificial sweeteners have been identified as new environmental contaminants, and can be found both in surface water and in underground aquifers.
The results of this study can help to understand the relative toxicity of artificial sweeteners and the potential for harmful effects on the microbial community of the intestine as well as on the environment.
