Impulsivity shapes diet and gut bacteria in healthy adults, study finds

Impulsivity in healthy adults is linked to unhealthy dietary choices, such as higher intake of alcohol and sugary drinks and lower fiber consumption. These dietary behaviors, in turn, are associated with changes in specific gut bacterial genera, highlighting an indirect pathway between personality traits and the gut microbiome.

New research reveals why fiber-rich diets fuel you better than refined foods

This study quantifies how much energy the human body harvests from gut microbial fermentation of dietary fiber, integrating bacterial physiology, diet, and metagenomic data. Results reveal that dietary fiber, not microbiome composition, mainly determines the amount of short-chain fatty acids absorbed, impacting daily energy and metabolic health.
