More and more evidence is arising that strongly suggests that the bacteria in our guts could be extremely influential in the way we conduct ourselves and make decisions. In fact, a recent study published in the journal BioEssays found that microbes in our guts can manipulate the way we behave and feel. It is thought that this occurs by altering neural signals travelling between the digestive tract and the brain in order to encourage us to feed on their preferred food source…which is usually sugar! Interestingly, researchers seem to be convinced that we can override these bacterial signals by starving the bacteria of that fuel source. This prompted researchers to suggest avoiding sugary foods for a few days in order to stop those sugar pangs!
