Salmon intake and gut health in adults

Primary Objective

DID SOMEONE SAY FREE SALMON?!? We need your help to learn more about how consuming salmon, and its bioactive compound astaxanthin, effects gut health and inflammation, as well as the underlying mechanisms linking whole food to health. The findings from this study will potentially inform future dietary recommendations and interventions, thereby reducing inflammation-associated diseases in humans.
