Study<\/strong><\/h4>\n<p>October 4, 2018 (ATLANTA) &#8212; A <a href=\"https:\/\/www.mdpi.com\/1420-3049\/23\/10\/2454\/htm\">study<\/a> recently published in the journal <em>Molecules<\/em> claimed that low- and no-calorie sweeteners (LNCS) are toxic to the gut <a href=\"https:\/\/caloriecontrol.org\/the-microbiome\/\">microbiome<\/a>. Using genetically-modified bioluminescent bacteria from E. coli as a sensing model, the authors sought to test the relative toxicity of six U.S. Food and Drug Administration (FDA)-approved LNCS (aspartame, sucralose, saccharin, neotame, advantame and acesulfame potassium-k (ace-k)) and that of ten LNCS-containing sports supplements and drew conclusions based on their findings. The authors suggest that the tested bioluminescent bacterial panel can potentially be used for detecting LNCS in the environment and that the study findings may aid in understanding the toxicity of these sweeteners on E. Coli, which they deem as representative of gut bacteria. The authors\u2019 conclusions are problematic for the reasons outlined below.<\/p>\n<p><strong>Conclusions From <em>In Vitro<\/em> Study Not Applicable to Human Subjects<\/strong><\/p>\n<p>First, while the authors draw conclusions about the impact of LNCS on the gut microbiome, the conditions in this <em>in vitro<\/em> study are not directly comparable to the human gut. Therefore, conclusions drawn from this study cannot be extrapolated to the digestive gut microbes that are unique to humans. In addition to the notation that some of the response levels of concentration in the study exceeded the amount typically found in real food samples, the reactions seen under these conditions may not mimic what would occur under real-life exposure conditions in humans. Furthermore, although there were changes noted in the bacterium included in the study, it is unknown whether these or any changes in microbiome bacteria, are indicative of negative health outcomes in humans.<\/p>\n<p><strong>Other Ingredients Not Accounted For<\/strong><\/p>\n<p>Regarding the testing of the toxicity of LNCS-containing sports supplements, the inability to isolate <img decoding=\"async\" width=\"180\" height=\"180\" class=\"size-full wp-image-16699 alignright\" src=\"http:\/\/caloriecontrol.org\/wp-content\/uploads\/Dr-Ashley-Roberts.jpg\" alt=\"\" srcset=\"https:\/\/caloriecontrol.org\/wp-content\/uploads\/Dr-Ashley-Roberts.jpg 180w, https:\/\/caloriecontrol.org\/wp-content\/uploads\/Dr-Ashley-Roberts-150x150.jpg 150w, https:\/\/caloriecontrol.org\/wp-content\/uploads\/Dr-Ashley-Roberts-95x95.jpg 95w\" sizes=\"(max-width: 180px) 100vw, 180px\" \/>the source of any change in the bacterium is a flaw. Given that commercially available supplements contain a number of complex ingredients, one would need to determine whether any responses seen are solely due to the sweetener and not the other ingredients. \u201cWhile examining the effect of these supplements may be of interest, without this sort of isolation and in the absence of a control group, it is difficult to draw sound conclusions,\u201d noted Dr. Ashley Roberts <em>(pictured)<\/em>, a regulatory toxicologist currently working with the Calorie Control Council.<\/p>\n<p><strong>Low Calorie Sweeteners Safety Proven For Decades<\/strong><\/p>\n<p>Lastly, it is important to note that each of the sweeteners included in the study have undergone extensive safety assessment and have been approved for use by scientific and regulatory authorities worldwide, including the U.S. FDA, the European Food Safety Authority and the Joint FAO\/WHO Expert Committee on Food Additives. LNCS are among the most studied ingredients which, in addition to their extensive history of safe use, provides a strong body of evidence in support of their safety.<\/p>\n<hr \/>\n<p>Dorin Harpaz, Loo Pin Yeo, Francesca Cecchini, et al.
