Can Fasting Modulate Infectious Disease?

SHR # 2792:: Can Fasting Modulate Infectious Disease? - Franziska Graef, PhD Candidate - Fasting before and during exposure to Salmonella enterica bacteria protects mice from developing a full-blown infection, in part due to changes in the animals’ gut microbiomes, according to new research published in PLOS Pathogens by Bruce Vallance and colleagues at University of British Columbia, Canada. When people or animals develop an infection, they often lose their appetite. However it remains controversial whether fasting protects a host from infection, or increases their susceptibility. In the new study, mice were fasted for 48 hours before and during oral infection with the bacteria Salmonella enterica serovar Typhimurium, a common cause of foodborne illness in people. NOTE: The show ended abruptly due to a complete power outage in our building that knocked the internet out as well. We covered all the important points of the study. Franziska will be back on because she has some fascinating perspectives on fasting.
