That humans are by and large a host for the bacteria in our gut and elsewhere -- and the degree to which these (happy or unhappy) tenants can impact our behavior -- is something I constantly struggle to find controversial. Look at the mountain of studies on T. Gondii alone, and then tell me with a straight face the several dozen odd other strains present in our gut microbiome under normal working conditions don't exert any similar sort of effect. "Happy bacteria, happy host" is my motto, I try to do things within reason to appease our tiny bacterial overloads. (Unless you get a bad bacteria, then condolences to you)
