A new friend on fitocracy (@tobywankenobe) shared this article about a sixth grader who may have discovered an insecticide by feeding sweeteners to fruit flies. He found that fruit flies died after eating Truvia (a stevia-based sweetener containing erythritol). It’s important to note that stevia was not the culprit, as consuming other stevia-based sweeteners that didn’t contain erythritol did not shorten the flies lives. Kind of makes you wonder how safe erythritol (a sugar alcohol used to sweeten foods with fewer calories than sugar) really is for us to consume. Here’s hoping that what’s bad for the flies is fine for the humans! At the very least, you might want to try using Truvia in your fruit fly traps this summer.
