Effect of spring oilseed rape crop density on plant root biomass and ... by Cepuliene, Rita; Marcinkeviciene, Ausra; Velicka, Rimantas; Kosteckas, Robertas; Pupaliene, Rita / Estonian Journal of Ecology.
A study in Washington State gathered 154 first to fifth graders from two elementary schools. The students were given four gummy bears made with either xylitol or maltitol (types of sugars used in many types of sugarless chewing gum) three times a day during school hours. All were checked for plaque and bacteria in their mouths at the start of the study and six weeks later.
It's at least a little funny that a tiny, colorful, candy version of a bear still has bones inside of it, just like the real thing! You can't feel those bones when you eat it, thankfully, but plenty of gummy bear brands add gelatin as an ingredient. Since this is 2015, however, companies have stepped up to the plate and introduced gelatin-free bears.
