The benefits of a healthy diet continue to mount: A new study published in Neurology suggests that seniors who eat leafy green vegetables such as spinach, kale, and collard greens every day experience less cognitive decline than those who eat little or no leafy greens.
The study, conducted at Rush Medical College and the Rush Institute for Healthy Aging in Chicago, involved 960 participants in the Memory and Aging Project. The participants – average age 81, none with a dementia diagnosis – underwent a yearly battery of tests to assess memory and cognition and provided information about their dietary habits and lifestyle.
The researchers divided the participants into five groups based on the amount of leafy greens they ate every day. Those who ate the most included an average of 1.3 servings in their diet each day, while those who ate the least had little or none. After five years, the researchers discovered, cognitive decline in those who ate the least amount of greens was about twice that of those who ate the most.
