In this study, researchers characterized the gut microbiota of breastfeeding mothers after collecting fecal samples from 2 days to 6 months postpartum. They found that the women’s gut bacterial communities were similar to those found in other adults; the gut communities were also relatively stable over the postpartum period.
Researchers also found associations between dietary components and the relative abundances of certain bacterial taxa: Increased Prevotella and decreased Bacteroides were associated with higher intakes of pantothenic acid, riboflavin, vitamin B6, and vitamin B12 in this group of women, while increased Firmicutes and decreased Bacteroidetes were correlated with higher intakes of copper, magnesium, manganese, and molybdenum.
Results showed that, overall, a diet higher in nutrients and calories was associated with more Firmicutes in the gut. Causality remains unclear, however, and scientists know little about the relationship between women’s health and the relative abundances of different bacteria.

Studies over the last decade have brought new hope that gut microbiome-targeted therapeutics might offer novel treatments for obesity. In this post, we ask whether dietary interventions, prebiotics, probiotics and medication that target the microbiome are useful for weight management.
The 11th Gut Microbiota for Health World Summit focused on emerging gut microbiome-targeted treatments in digestive, immune and cardiometabolic health. This post highlights the major take-aways from the conference and explores how they might impact clinical practice in the foreseeable future.
Following the GMFH 2022 Year at a Glance report, it is time for a flashback in the latest research on cancer microbiome. This post ranges between the epidemiology, etiology and diagnosis of cancer, looking at the role of fungal and bacterial gut microbiome in all three health care branches.
