Hypothesis
Higher dietary manganese intake is associated with retinal imaging markers in individuals at risk for Alzheimer's disease.
Conclusion
The study found that higher dietary manganese intake was linked to lower CRAE HZC density in the right eye, but no significant associations were observed for the Pyramid score or longitudinal data.
Supporting Evidence
- Higher dietary manganese intake was associated with lower CRAE HZC density in the right eye.
- Participants had a moderate mean Pyramid score comparable to other UK cohorts.
- The study included both cross-sectional and longitudinal analyses.
Takeaway
Eating foods with manganese might help keep your eyes healthy, especially for people worried about Alzheimer's, but more research is needed.
Methodology
The study used generalised additive models to analyze cross-sectional and longitudinal data on diet and retinal imaging markers.
Limitations
The sample size was small and further research is needed with a larger group.
Participant Demographics
Mean age 50.87 years, majority female (57%), with 36% being APOEe4 carriers.
