Probiotics contained in yogurt and some biological supplements to decrease stress and anxiety. To such conclusion the American scientists from University of Missouri.
As a model organism experts used aquarium fish Danio rerio, which in experiments of this kind are quite often used. As it turned out, those fish food containing probiotics, to a lesser extent, were prone to anxiety and susceptible to stress than zebrafish trapped in a “control group”.
