Follow Friday: Fruit fly traps



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.

  1. Well erythritol is perfectly safe, and has been regulated by all major governments (U.S, E.U, etc), this is an example of how “natural” does not always mean “good for you”. Many fruits naturally contain erythritol, which probably evolved to stop insects eating the fruits. Also, etythritol is contained in the stevia leaf, but in doses too small for the sweetener.
