The survey

The study enrolled volunteers who were already participating in the Rush Memory and Inving project, which was running in 1997 among residents of Chicago retirement communities and public housing estates. A “food frequency questionnaire” was added from 2004 to February 2013, completing 1.068 participants. Of these, 960 also received at least two cognitive assessments for cognitive change analysis.


These 960 people at the start of the study had a mean age of 81 and had no signs of dementia. The scholars tested their thinking and memory skills each year and were followed up for an average of 4,7 years. Participants also completed food frequency questionnaires, which assessed the frequency and number of servings of spinach; cabbage / kale / collard greens or a portion of salad / lettuce.


The study divided the participants into five groups based on how often they ate green leafy vegetables and then compared the cognitive ratings of those who ate the most (an average of about 1,3 servings per day) and those who ate. less (0,1 servings per day).

After several years of follow-up, the rate of decline for those who ate green leafy vegetables it was 0,05 slower than the rate for those who ate none. This difference was equivalent to about 11 years.

Researchers say that for now further research is also needed on younger populations to confirm these results, which in any case also took into account other factors such as fish and alcohol consumption, smoking, possible hypertension and obesity, level of education and quantity. of physical and cognitive activities.
