Neuroscientists have, for the first time, shown that gut bacteria “speak” to the brain to control food choices in animals. In a study publishing in the Open Access journal PLOS Biology, researchers identified two species of bacteria that have an impact on animal dietary decisions.
the gut bacteria “seem to induce some metabolic change that acts directly on the brain and the body, which mimics a state of protein satiety,”
Interesting study that may explain why some people seem to crave certain foods while other people have no interest. This study was on fruit flies and needs a lot more work before it can correlate to humans. Interesting observation.
