Artificial sweeteners could cause spikes in blood sugar
The Washington Post

Artificial sweeteners might be triggering higher blood sugar levels in some people and contributing to the problems they were designed to combat, such as diabetes and obesity, according to new findings published Wednesday in the journal Nature.

Although the precise reasons behind the blood sugar changes remain uncertain, researchers suspect that artificial sweeteners could be disrupting the microbiome, a vast and enigmatic ecosystem of bacteria in our guts.

In a series of experiments, researchers found that several of the most widely used types of non-calorie sweeteners in food and drinks — saccharin, sucralose and aspartame — caused mice to experience increased risk of glucose intolerance, a condition that can lead to diabetes.
