MICROBIOTA AND MENTAL HEALTH

Kids' behavior, socioeconomic risk linked to gut microbiome composition, function. Oregon State University. https://medicalxpress.com/journals/mbio/


A study of early school-aged children shows a connection between the bacteria in their gut and their behavior, and that parents play a key role in their kids' microbiome beyond the food they provide.

Gut microbiome composition and diversity are related to human personality traits; Katerina V.A.Johnson; Human Microbiome Journal, 21 December 2019, 100069. https://doi.org/10.1016/j.humic.2019.100069


Highlights • Investigation of gut microbiome composition and diversity with respect to human personality. • Analyses targeted bacterial genera linked to behaviour in animal and human psychiatric studies. • Bacterial genera were modelled (using negative binomial regression) with respect to personality. • Genera linked to autism are also related to social behaviour in the general population. • Sociability is associated with higher diversity, and anxiety and stress with reduced diversity.

Urban-type lifestyle seemed almost to double the prevalence of allergies in dogs living in rural environments compared with dogs with rural-type lifestyle in rural environments.”
