Methods
This study looked at the association between plasma carotenoids and cognition among 295 participants at risk for cognitive decline and enrolled in the MIND diet study.
Key Findings
Key Findings: Results showed that high blood levels of α-carotene, reflecting higher intakes of certain foods including nuts, was associated with better cognition in a population at risk for Alzheimer’s Disease in the US.
Although nuts like peanuts do not contain high levels of vitamin A, it is possible that the fat in peanuts may increase the bioavailability and bioconversion of vitamin A.
