The Human Microbiome, nutrition, and healthiness: Workshop Summary summarizes the shows and discussions that happened throughout the workshop.

  1. The microbiome is fundamental to human body structure, healthiness, and disease.
  2. The microbiome is arguably the main intimate connection that people have with their exterior atmosphere, usually via diet.
  3. Given the rising nature of study at the microbiome, a few very important technique matters may perhaps nonetheless must be resolved with appreciate to undersampling and a scarcity of causal and mechanistic studies.
  4. Dietary interventions meant to impact host biology through their impression at the microbiome are being constructed, and the marketplace for those items is seeing large good fortune. besides the fact that, the present regulatory framework poses demanding situations to curiosity and investment.

Scientists are beginning to recognize the microbiome as an extra level of biological complexity that is integral to human physiology, health, and disease. Some workshop participants perceived the microbiome as an extension of human metabolism, with gut bacteria playing key roles in host metabolism. Native bacteria impact not only which dietary components their host is able to extract from its diet, but also how those dietary components are converted into biological signals. Gut microbes also impact host energetics.

An audience member suggested that sampling from the small intestine would be more informative than sampling from fecal samples or from the esophagus. Nelson agreed that the field needs to move in a direction where scientists are sampling from other parts of the GI tract, but researchers have done as well as they have been able in the early stages. Sampling from the small intestine would be more invasive than fecal sampling. She suggested that more cross-­ disciplinary dialogue, in this case with medical researchers, could help move the field in that direction.
