A study recently published in Neurology finds that healthy seniors who had daily helpings of leafy green vegetables — such as spinach, kale and collard greens — had a slower rate of cognitive decline, compared to those who tended to eat little or no greens.
Some prior research has pointed to a similar benefit. A study of women published in 2006 also found that high consumption of vegetables was associated with less cognitive decline among older women. The association was strongest with greater consumption of leafy vegetables and cruciferous vegetables — such as broccoli and cauliflower.
