Personalized diets based on gut microbes to help prevent Alzheimer's
Towards Precision Nutrition for Alzheimer's Dementia Prevention: A Prospective Study of Dietary Patterns, the Gut Microbiome and Cognitive Function
Seeing if tailoring healthy diets to a person's gut microbes can help protect thinking and memory in older adults at risk for Alzheimer's.

What this research studies
You would be followed over time while the study links what you eat, your gut microbes, and changes in memory and thinking. You'd provide stool samples, fill out detailed diet questionnaires, and take brief cognitive tests while researchers perform high-resolution analysis of the gut microbiome and other molecular measures. The team will look for patterns showing which healthy dietary patterns help thinking for people with different gut microbial profiles. The goal is to lay groundwork for personalized, microbiome-informed diet recommendations to lower dementia risk.
Who could benefit from this research
Good fit: Adults concerned about cognitive decline, especially older adults (commonly 65+), who are willing to provide stool samples, dietary information, and complete cognitive testing would be ideal candidates.
Not a fit: People with advanced Alzheimer's disease or severe cognitive impairment, or those unwilling to provide stool samples or share diet information, are unlikely to benefit directly from participation.
Why it matters
Potential benefit: If successful, this work could lead to personalized diet advice that better preserves memory and thinking and reduces Alzheimer's risk for individuals.
How similar studies have performed: Population studies and at least one randomized trial suggest healthy diets support cognitive health, but tailoring diets by an individual's gut microbiome is a new approach not yet proven in humans.
