Exploring how gut bacteria and flavonoids can support brain health in aging adults

MAEVE: Microbiota mediated flavonoid metabolites for cognitive health

['FUNDING_R01'] · UNIVERSITY OF CALIFORNIA LOS ANGELES · NIH-10881057

This study is looking at how eating a Mediterranean diet full of healthy foods might help older adults, especially those at risk for Alzheimer's, keep their brains healthy by changing the bacteria in their gut. If you join, you might try some new foods and share how they affect your thinking and gut health!

What this research studies

This research investigates the relationship between dietary flavonoids, gut microbiota, and cognitive health in older adults, particularly those at risk for Alzheimer's disease. It focuses on how a Mediterranean diet rich in polyphenols may help preserve brain function and structure by influencing gut bacteria and their metabolites. The study aims to understand the mechanisms through which these dietary components can potentially delay cognitive decline and improve overall brain health. Participants may be asked to modify their diets and undergo assessments to evaluate changes in cognitive function and gut microbiome composition.

Who could benefit from this research

Good fit: Ideal candidates for this research are older adults who are at risk for Alzheimer's disease or cognitive decline.

Not a fit: Patients who are not at risk for cognitive decline or those with advanced Alzheimer's disease may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to dietary recommendations that help prevent or slow cognitive decline in older adults.

How similar studies have performed: Previous research has shown promising results in using dietary interventions to support cognitive health, suggesting that this approach may be effective.
