Children whose saliva produced high amounts of sulfur volatiles disliked raw Brassica vegetables the most. The levels of sulfur volatiles were similar in parents and children, suggesting a shared oral microbiome. However, the relationship between sulfur volatiles and the dislike of Brassica vegetables was not as high in adults, suggesting they may have learned to tolerate the taste of the vegetables over time.
An overgrowth in the gastrointestinal tract of the bacteria Klebsiella in preterm babies was associated with an increased presence of certain immune cells and the development of neurological damage. The findings suggest a link between microbiota and brain development.
There is a growing body of evidence linking depression to microbiome health. A new study proposes focusing on the microbiome may help alleviate some of the symptoms of depression associated with the COVID-19 pandemic.
Study reaffirms findings that the gut microbiome may play a significant role in cognitive decline. Researchers found, in mice, a ketogenic diet, hypoxia, and the Bilophila wadsworthia bacteria impaired the hippocampus, leading to signs of cognitive decline.
Infant boys with a gut bacterial composition high in Bacteroidetes were found to have more advanced cognitive and language skills one year later compared to boys with lower levels of the bacteria.
Researchers identified the gut bacteria E. faecalis as a mediator of social behavior and corticosterone levels in mice.
Gut microbes that metabolize tryptophan secrete indoles that stimulate the development of new neurons in the adult brain.
Intermittent fasting can help to reduce hypertension by reshaping the gut's microbiome.
