    • Experiences of discrimination are associated with adverse health outcomes, including obesity. However, the mechanisms by which discrimination leads to obesity remain unclear. Utilizing multi-omics analyses of neuroimaging and fecal metabolites, researchers investigated the impact of discrimination exposure on brain reactivity to food images and associated dysregulations in the brain–gut–microbiome system.

  • Discrimination alters brain-gut ‘crosstalk,’ prompting poor food choices and increased health risks (2023)
    • People frequently exposed to racial or ethnic discrimination may be more susceptible to obesity and related health risks in part because of a stress response that changes biological processes and how we process food cues. Arpana Gupta, PhD, co-director of the Goodman-Luskin Microbiome Center, was interviewed on the study that directly examined the effects of discrimination on responses to different types of food as influenced by the brain-gut microbiome system.

  • You are what you eat: Diet may affect your mood and brain function (2023)
    • If you struggle with mood changes and other behavioral health issues, there’s a chance that your diet has something to do with it. Arpana Gupta, PhD, co-director of the Goodman-Luskin Microbiome Center, and Shelby Yaceczko, MS, RDN-AP, CNSC, CSSD, advanced practice dietitian, discuss what the gut-brain system is, and how diet can affect it.
