Key Moments
Artificial sweeteners gave mice diabetes via microbiome changes
Professor Eran Elinav's research found that saccharin, previously thought inert, caused blood sugar disturbances in mice by altering the gut microbiome. Transplanting microbes from affected mice into healthy recipients induced diabetes, proving the microbiome was driving the effect. This landmark study was published in Nature in 2014.
"To our astonishment, his results were that these mice were developing a higher tendency to develop disturbances in their blood sugar control. They were kind of leaning towards the development of diabetes."
Half of people react to artificial sweeteners, half don't
In a human trial with saccharin, half the participants showed worsened blood sugar control while the other half were completely unaffected. None improved. This was a foundational moment for the personalized nutrition concept, showing that identical foods can have opposite effects depending on an individual's microbiome.
"Half the people who were exposed to saccharin didn't care at all. They didn't change their blood sugar control. But the other half of them actually worsened their blood sugar control."
