Effect of symbiotic ice cream supplementation on immune response, general health, sleepiness and mood of military in field training

The aim of this study was to evaluate the effect of symbiotic ice cream supplementation on immune response, mood and health parameters of military volutaries from the Escola Preparatoria de Cadetes (Army Preparatory School) from Campinas during field training. This evaluation was done through the collection of saliva for the evaluation of IgA and through the application of questionnaires in three phases: after the washout period (t = 0), after supplementation in the period prior to field training (t = 1 ) and after field training (t = 2). It was possible to observe that after training there was a significant decrease in salivary IgA for both symbiotic and placebo group. In addition, the symbiotic group had significantly increased tranquility and reduced tension after training while the placebo group did not show changes in both states after training. These results demonstrate the importance of investigating the effects of probiotics associated with prebiotics on gut-brain axis.
