Summary

This study tests a 10-week nutrition program in 61 older adults (ages 55-85) from rural North Florida, some with mild cognitive impairment and some without. Participants follow either a Mediterranean diet or a modified Mediterranean-ketogenic diet. The goal is to see if the program improves gut health and brain function, and whether it can be scaled up for wider use.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Modified Mediterranean-Ketogenic diet and Mediterranean diet
What this could lead to: If successful, this could show that a simple nutrition program helps support brain health and slow cognitive decline in older adults.
What could go wrong: This is a small, early-stage study with only 61 participants, so results may not apply widely. It focuses on adherence and gut markers, not yet on proven cognitive benefits.
