Non-nutritive sweeteners have long been seen as a healthier alternative to sugar, but recent research has shed light on potential interactions these sweeteners may have on sugar handling in the body.
A team of researchers from the University of Adelaide conducted a study to investigate the impact of sweeteners like Splenda on blood glucose control. Previous studies have suggested a link between high consumption of sweeteners and an increased risk of developing type 2 diabetes.
The findings of the study were published in the journal Nutrients, showcasing the results of a two-week preclinical study. Associate Professor Richard Young, Senior Research Fellow at the Adelaide Medical School, explained the team’s approach in the study.
“In this proof-of-concept study, we wanted to discover how non-nutritive sweeteners like sucralose (Splenda) and acesulfame-K might alter sugar handling,” said Professor Young. “Specifically, whether these sweeteners interact with sweet sensing pathways in the gut that govern the rate of sugar uptake directly, or indirectly through effects on gut bacteria.”
The researchers administered sucralose and acesulfame-K to mice over a two-week period, with half of the mice also receiving antibiotics to clear their gut bacteria. The results showed that the mice who received the sweeteners absorbed sugar at a faster rate from their gut compared to those who didn’t, indicating a direct effect of the sweeteners on sugar uptake in the intestine. Interestingly, the overall blood sugar responses did not change with the administration of the sweeteners.
Dr. Braden Rose, Early Career Postdoctoral Researcher at the Adelaide Medical School, highlighted the significance of these findings. “These findings go a long way to answering some of the fundamental questions we have around the effects of non-nutritive sweeteners and show that despite the misconception that they are metabolically inert, their habitual high intake can alter distinct mechanisms of sugar handling.”
Moving forward, the research team plans to conduct clinical testing to further explore the effects of non-nutritive sweeteners on sugar handling. The researchers involved in the study were also part of the Lifelong Health theme at the South Australian Health and Medical Research Institute.

In conclusion, the study highlights the need for further research on the effects of non-nutritive sweeteners on sugar handling in the body. As the prevalence of sweeteners in the diet continues to rise, it is essential to understand the potential implications for overall health and well-being.
