itemprop=description content=Researchers have identified a potential link between experiences of discrimination and increased obesity risk by examining neural responses to food cues and gut metabolites. The study reveals that discrimination may influence unhealthy food choices, potentially disrupting the brain-gut connection, and suggests brain-targeted treatments or dietary changes as potential interventions.
By Neha MathurOct 8 2023Reviewed by Sophia Coveney In a recent article published in the Journal of Nature Mental Health, researchers examined neural reactivity to unhealthy and healthy food cues and gut metabolites to elucidate potential mechanisms linking discrimination and obesity.
In response to discrimination-related stress, it likely activates the brain's reward and cognitive control networks, deactivating frontal executive modulation and potentiating brain activity in limbic regions, triggering people to eat energy-dense, unhealthy foods. Further, they provided samples for fecal metabolomics, clinical and behavioral measures, and functional magnetic resonance imaging .
They could see each picture for three seconds and give responses ranging from 0 to 10, indicating their intention to eat those food items.to fetch clusters that they combined to develop a discrimination-related food-cue region of interest mask and do a structural equation model analysis. Results Unhealthy sugar-rich foods have a rewarding and analgesic nature, and frontal-striatal regions control feeding behavior in response to reward and hedonic aspects of food.
