15 August 2014 - ScienceDaily- Do gut bacteria rule our minds? In an ecosystem within us, microbes evolved to sway food choices

Bacteria within us - which outnumber our own cells about 100-fold - may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity.

FAB RESEARCH COMMENT:

Please find the underlying research here:

Alcock et al, 2014 - Is eating behavior manipulated by the gastrointestinal microbiota?

In an article published this week in the journal BioEssays, researchers from UC San Francisco, Arizona State University and University of New Mexico concluded from a review of the recent scientific literature that microbes influence human eating behavior and dietary choices to favor consumption of the particular nutrients they grow best on, rather than simply passively living off whatever nutrients we choose to send their way.

While it is unclear exactly how this occurs, the authors believe this diverse community of microbes, collectively known as the gut microbiome, may influence our decisions by releasing signaling molecules into our gut. Because the gut is linked to the immune system, the endocrine system and the nervous system, those signals could influence our physiologic and behavioral responses.
