Here's a crazy fact: Thanks to soda and the sneaky added sugars in store-bought foods, 25% of Americans consume a diet that is 25% sugar.

Scientists are still trying to figure that out. Scicurious breaks down a recent study in mice that successfully demonstrates both why our sugar intake has health experts concerned AND why we don't yet know exactly what we're doing to ourselves.
