Cognitive decline in older adults may be slowed through their consumption of green leafy vegetables, according to new research. Nine hundred and fifty-four participants averaging 81 years old took part in a Rush Hospital Memory and Aging Project. Over approximately 4.5 years, their cognitive faculties were closely measured. The goal was to discover whether nutrients found in green leafy vegetables reduced cognitive decline. Solid evidence, after other factors accounted for, showed that cognitive decline in older adults was indeed slowed in those who consumed green leafy vegetables. These vegetables are rich in folate, phylloquinone, lutein, and beta carotene, which are found in arugual; romaine lettuce; "spring mix"; spinach; kale' collard; turnip, and mustard greens; watercress; chard; broccoli rabe; and Chinese broccoli.
