You are what you eat

23 January 2015

A new study has provided further insight on the relationship between proteins from the intestine and the human central nervous system.

Published in the Journal of Medicinal Food, the report focuses on the hundred trillions of bacteria living in an adult human, which mostly reside in the intestines. These have a significant impact on behaviour and brain health, with there being many ways that gut bacteria can impact normal brain activity and development, affect sleep and stress responses, as well as playing a key role in diseases. However, these can be controlled through diet.

In the study, the author examines the various mechanisms through which the gut bacteria can affect the brain by either stimulating or over-stimulating the immune system. It can also produce neurotoxic agents and release hormones or neurotransmitters, which are identical to those made by the human body.

"The microbiome has become a hot topic in many branches of medicine, from immune and inflammatory diseases, such as Crohn's and IBD to cardiovascular diseases," says co-editor-in-chief Professor Sampath Parthasarathy, Florida Hospital Chair in Cardiovascular Sciences, University of Central Florida.
