New lab paper: The microbes we eat: abundance and taxonomy of microbes consumed in a day’s worth of meals for three diet types

A new paper out from my lab (with Jenna Lang as the 1st author and in collaboration with Angela Zivcovic from the UC Davis Food For Health Initiative and the Department of Nutrition):  The microbes we eat: abundance and taxonomy of microbes consumed in a day’s worth of meals for three diet types.  The work in the paper focuses on characterizing the abundance and taxonomy of microbes in food from three model diets.Basically, Angela prepared meals for these three dietsFood was purchased and prepared in a standard American home kitchen by the same individual using typical kitchen cleaning practices including hand washing with non-antibacterial soap between food preparation steps, washing of dishes and cooking instruments with non-antibacterial dish washing detergent, and kitchen clean-up with a combination of anti-bacterial and non-antibacterial cleaning products. Anti-bacterial products had specific anti-bacterial molecules added to them whereas “non-antibacterial” products were simple surfactant-based formulations. The goal was to simulate a typical home kitchen rather than to artificially introduce sterile practices that would be atypical of how the average American prepares their meals at home. All meals were prepared according to specific recipes (from raw ingredient preparation such as washing and chopping, to cooking and mixing).And then she blended them and we characterzied the microbial communities in the blended samples:After food preparation,...
