What’s in Your Gut and How to Change It

W Turpin et al. Gastroenterol 2022; 163: 685-698. Open access! Mediterranean-Like Dietary Pattern Associations With Gut Microbiome Composition and Subclinical Gastrointestinal Inflammation

As part of the Genetic, Environmental, Microbial (GEM) Project, the researchers recruited a cohort of 2289 healthy first-degree relatives of patients with Crohn’s disease. Diet was assessed with a food frequency questionnaire. Key finding: A Mediterranean-like dietary pattern is associated with microbiome (increased Ruminococcus, as well as taxa such as Faecalibacterium) and lower intestinal inflammation.

Uncovering 1058 Novel Human Enteric DNA Viruses Through Deep Long-Read Third-Generation Sequencing and Their Clinical Impact This study discovered 1058 novel human gut viruses, and these findings can contribute to current viral reference genome, future virome investigation, and colorectal cancer diagnosis. From the editorial: “Previous literature also identified virome signatures associated with certain diseases, such as colorectal cancer14 or inflammatory bowel disease,15 such that a better understanding of the viral dark matter may be used to develop biomarkers to identify individuals at risk or even to influence gut physiology.”
