Gut-brain axis: Prebiotics may alter food decision-making in overweight adults

16 Oct 2023 — New research indicates that consumption of high-dose dietary prebiotics may reduce reward-related brain activation in response to high-calorie food. The German-based researchers suggest that functional microbial changes underlie this altered brain response to high-calorie food. 

In the clinical trial, the research team used advanced neuroimaging, next-generation sequencing of gut bacteria and combined analyses of potential metabolic pathways.
