Choline is a crucial methyl donor necessary for epigenetic regulation. In this issue of Cell Host & Microbe, Romano et al. (2017) demonstrate that choline-utilizing gut bacteria compete with their host for this essential resource, calling for a systematic consideration of gut microbial composition for personalized diet recommendations.
