Changing dietary fats to support thinking in older adults
Fatty Acid Modulation of Brain Function in Older Adults
This project looks at whether short, planned swaps in the types of fats you eat can quickly improve thinking and memory in people aged 65–75 without dementia.

What this research studies
You would follow a short, supervised diet plan while researchers measure your brain function and thinking. Each person first follows a low-fat control week and then, in random order, tries two different one-week experimental diets that differ in the balance of palmitic (saturated) and oleic (monounsaturated) acids. The study uses a crossover design so every participant experiences both experimental diets, allowing direct comparisons within the same person. Researchers will collect cognitive tests and brain-function measurements before and after each diet period to look for quick changes.
Who could benefit from this research
Good fit: Ideal candidates are men and women aged 65–75 who are cognitively normal (no dementia) and are able to follow the short dietary protocols and attend in-person visits.
Not a fit: People with moderate-to-severe dementia, those outside the 65–75 age range, or those who cannot follow the diet for medical or practical reasons are unlikely to benefit directly from participating.
Why it matters
Potential benefit: If successful, simple short-term changes in the types of dietary fats could quickly improve thinking and memory in older adults and point to easy dietary strategies to help people with mild cognitive concerns.
How similar studies have performed: Animal studies and some short human studies support that reducing saturated fat can acutely improve brain function, but using a controlled PA/OA crossover diet in older adults is a relatively new approach.
