Artificial sweeteners are a popular way to cut calories and sugar from your diet. They’re found in many products, from drinks to snacks and even some medications. But what do we really know about these chemicals? It turns out that there’s still a lot we don’t know about how they work in our bodies. A new study published by researchers at the University of Washington School of Medicine has found that artificial sweeteners can alter glucose levels in healthy adults and potentially cause harm when used incorrectly by people with diabetes, who already have problems managing blood sugar levels.
A study published in the journal Diabetes Care found that consuming saccharin and sucralose harmed the ability of healthy adults to dispose of glucose in their bodies, while artificial sweeteners did not seem to affect the glucose levels of adults with diabetes.
A study published in the journal Diabetes Care found that consuming saccharin and sucralose harmed the ability of healthy adults to dispose of glucose in their bodies, while artificial sweeteners did not seem to affect the glucose levels of adults with diabetes. Study participants were healthy adults and those who had been diagnosed with type 2 diabetes. Researchers gave each person a beverage containing 65 grams of pure glucose, which is equivalent to what most people would consume with two slices of bread. The researchers then measured how quickly blood sugar levels rose after drinking the beverage and found that those who had consumed sucralose reacted differently than those who did not consume any artificial sweeteners.
The researchers suggest that these findings should prompt doctors to reconsider whether they recommend artificial sweeteners as a means to control blood sugar levels.
The researchers suggest that these findings should prompt doctors to reconsider whether they recommend artificial sweeteners as a means to control blood sugar levels. “It’s important to keep in mind that our study was observational, so we can’t make conclusions about cause and effect,” said lead author Ryan Zarychanski, MD, PhD. “But our results suggest that people with diabetes may want to limit their consumption of artificial sweeteners until we know more about how they affect metabolism.”
Personal stories like these are common on the internet – claims that artificial sweeteners caused a dramatic rise in glucose readings for people with diabetes.
The article is referring to a recently published laboratory study that was done on healthy adults. The researchers used artificial sweeteners and regular sugar in drinks with different levels of calories, then tested the effect on blood sugar levels. It’s important to note that this study did not test people with diabetes, nor did it test type 1 or type 2 diabetes specifically – only healthy participants were included in the study. Because this lab experiment has been misconstrued as evidence against using artificial sweeteners, we wanted to make sure you understand what actually happened:
The authors also caution that people with type 2 diabetes have a different glucose response to artificial sweeteners and may be more at risk of negative effects from them, as many with type 2 diabetes already have impaired blood sugar regulation.

The findings do not apply to other groups, such as pregnant women or children.
The researchers also studied how study participants metabolized glucose after drinking artificially sweetened drinks by testing their blood sugar levels.
Another part of the study tested participants’ ability to metabolize glucose after drinking artificially sweetened drinks. The researchers found that blood sugar levels were higher after consuming artificially sweetened drinks than they were before, and participants’ ability to metabolize glucose was reduced.

Glucose is regulated by several hormones in the gut, so one explanation for the changes seen in study participants is that artificial sweeteners in the gut could change gut bacteria or otherwise alter hormone signaling. It’s important to note that these findings are limited to healthy young adults, and more research is needed before we can draw any conclusions about whether or not artificial sweeteners affect our blood sugar levels.
Sweeteners in the gut could change gut bacteria or otherwise alter hormone signaling.
While there’s no definitive evidence that artificial sweeteners can harm your gut bacteria, the hypothesis has been around for some time. Some studies have shown that artificial sweeteners alter the composition of gut bacteria, which may be linked to metabolic disorders such as obesity and diabetes. It’s also possible that these compounds could alter hormone signaling in the body—a link that might also explain whether or not they would raise blood sugar levels.
- In terms of diabetes, this is a significant concern. Artificial sweeteners have been shown to cause an insulin response in people who are normal weight but not overweight or obese—and diabetics should avoid them altogether because they can raise blood sugar levels even more than regular sugar does!
Artificial sweeteners appear to be less safe than previously assumed.
A new study published in JAMA Internal Medicine found that artificial sweeteners may not be as safe as we once thought. The study was small and only included participants who did not have diabetes and had normal glucose tolerance (i.e., they didn’t have any kind of condition that causes them to experience changes in their blood sugar). But it’s still worth paying attention to: the researchers found that people who regularly consumed diet drinks were at a higher risk for developing high blood sugar than those who didn’t use artificial sweeteners. The results may not apply to people with diabetes or other health conditions, but it’s important for everyone—especially those with diabetes—to understand the potential dangers of using too many artificial sweeteners.
Conclusion
So, should you avoid artificial sweeteners? The answer is “maybe.” If you want to keep your diabetes in check, it may be wise to avoid or at least limit them. But if you think about your overall nutrition and the other foods that you eat, artificial sweeteners probably aren’t going to make or break your health. In fact, they may even help by reducing calories from other sources like sugar-sweetened beverages.
