Vegetable types and dementia risk in older women
Beyond total vegetable intake, did specific types of vegetables show different associations with dementia-related hospitalization or death after age 80?
Human · long-term observational cohort study
Key findings
Different associations by type
Some lower-risk associations appeared for yellow, orange, and red vegetables, allium vegetables, and green leafy vegetables.
Differences by intake range
For total vegetable intake, the third quartile had a lower risk of dementia death than the lowest quartile, but the same association was not found in the highest quartile.
Observations across vegetable groups
The main signal in the paper was observed across several vegetable groups.
Study design
Baseline dietary questionnaires from 1,206 Australian women aged 70 and older were linked with 14.5 years of medical records. There were 207 dementia-related hospitalizations or deaths after age 80.
