The Gut Microbiome and Abiotic Factors as Potential Determinants of Postprandial Glucose Responses: A Single-Arm Meal Study
Nestel et al. 2021

The gut microbiome has combined with other person-specific information, such as blood parameters, dietary habits, anthropometrics, and physical activity been found to predict personalized postprandial glucose responses (PPGRs) to various foods. Yet, the contributions of specific microbiome taxa, measures of fermentation, and abiotic factors in the colon to glycemic control remain elusive. We tested whether PPGRs 60min after a standardized breakfast was associated with gut microbial a-diversity (primary outcome) and explored whether postprandial responses of glucose and insulin were associated with specific microbiome taxa, colonic fermentation as reflected by fecal short-chain fatty acids (SCFAs), and breath hydrogen and methane exhalation, as well as abiotic factors including fecal pH, fecal water content, fecal energy density, intestinal transit time (ITT), and stool consistency.

Settlers of our inner surface – factors shaping the gut microbiota from birth to toddlerhood
Laursen et al. 2021

During the first 3 years of life, the microbial ecosystem within the human gut undergoes a process that is unlike what happens in this ecosystem at any other time of our life. This period in time is considered a highly important developmental window, where the gut microbiota is much less resilient and much more responsive to external and environmental factors than seen in the adult gut. While advanced bioinformatics and clinical correlation studies have received extensive focus within studies of the human microbiome, basic microbial growth physiology has attracted much less attention, although it plays a pivotal role to understand the developing gut microbiota during early life. In this review, we will thus take a microbial ecology perspective on the analysis of factors that influence the temporal development of the infant gut microbiota. Such factors include sources of microbes that seed the intestinal environment, physico-chemical (abiotic) conditions influencing microbial growth and the availability of nutrients needed by the intestinal microbes.

In vitro ecology: a discovery engine for microbiome therapies
Hernandez-Sanabria et al. 2020

To therapeutically modulate gut microbial ecosystems, a better understanding of gut ecology is key. High-throughput in vitro ecology provides a tool with the necessary power to address these needs and interpersonal treatment response variation.

The metabolic nature of individuality
Lars O. Dragsted, 2020

A diet-controlled study indicates that metabolic flexibility is an important driver of inter-individual difference in the response to dietary change, and a high flexibility score is a likely health asset.
