How controlled diets affect gut health and brain function

Project 2 - Influence of controlled diets on gut microbiome, metabolome and cognitive function

['FUNDING_OTHER'] · DUKE UNIVERSITY · NIH-10693930

This study is looking at how different diets can change the bacteria in our gut and how those changes might affect our brain health, especially for people concerned about Alzheimer's disease, so participants will follow specific eating plans to help us learn more about this connection.

What this research studies

This research investigates how different dietary interventions can influence the gut microbiome, which is the community of microorganisms in our intestines, and how these changes may impact cognitive function, particularly in relation to Alzheimer's disease. By analyzing blood and fecal samples, the study aims to identify metabolic changes associated with diet and their potential effects on brain health. Patients may participate in controlled dietary programs to help researchers understand the relationship between diet, gut health, and cognitive decline.

Who could benefit from this research

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

Not a fit: Patients who are not experiencing cognitive decline or who have other neurological conditions unrelated to Alzheimer's may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to dietary recommendations that help slow cognitive decline and improve brain health in individuals at risk for Alzheimer's disease.

How similar studies have performed: Previous studies have shown promising results in understanding the link between diet, gut microbiome, and cognitive function, suggesting that this approach could yield valuable insights.
