"Adding a daily serving of light-green leafy vegetables to your diet may hold out a unproblematic means to assist promote encephalon health," said study writer Martha Clare Morris, ScD, a nutritional epidemiologist at Rush.
"There continues to hold out sudden increases inward the per centum of people with dementia equally the oldest historic menstruum groups piece of employment along to grow inward number. Effective strategies to foreclose dementia are critically needed."
The study results propose that people who ate 1 serving of green, leafy vegetables had a slower charge per unit of measurement of spend upwards on tests of retentiveness together with thinking skills than people who rarely or never ate them. The study results also propose that older adults who ate at to the lowest degree 1 serving of leafy light-green vegetables showed an equivalent of beingness eleven years younger cognitively.
960 older adults completed nutrient questionnaires together with received annual cognitive assessments
The study enlisted volunteers already participating inward the ongoing Rush Memory together with Aging Project, which began inward 1997 alongside residents of Chicago-area retirement communities together with senior populace housing complexes. Influenza A virus subtype H5N1 "food frequency questionnaire" was added from 2004 to Feb 2013, which 1,068 participants completed. Of them, 960 also received at to the lowest degree ii cognitive assessments for the analyses of cognitive change.
This study involved these 960 people, who at the study commencement were an average historic menstruum of 81 years one-time together with did non accept dementia. They had their thinking together with retentiveness skills tested every twelvemonth together with were followed for an average of 4.7 years. The participants also completed the nutrient frequency questionnaire, which assessed how frequently together with how many half-cup servings they ate of either spinach; kale/collards/greens; or a one-cup serving of lettuce/salad.
The study divided the participants into 5 groups based on how frequently they ate light-green leafy vegetables, together with compared the cognitive assessments of those who ate the most (an average of most 1.3 servings per day) together with those who ate the to the lowest degree (0.1 servings per day).
Overall, the participants' scores on the thinking together with retentiveness tests declined at a charge per unit of measurement of 0.08 standardized units per year. Over 10 years of follow-up, the charge per unit of measurement of spend upwards for those who ate the most leafy greens was slower yesteryear 0.05 standardized units per twelvemonth than the charge per unit of measurement for those who ate the to the lowest degree leafy greens. This divergence was equivalent to beingness eleven years younger inward age, according to Morris.
More enquiry needed inward younger together with minority populations
The results remained valid afterward accounting for other factors that could touching on encephalon health, such equally seafood together with alcohol consumption, smoking, high blood pressure, obesity, teaching degree together with amount of physical together with cognitive activities.
"The study results produce non evidence that eating green, leafy vegetables slows encephalon aging, only it does present an association," Morris said. "The study cannot dominion out other possible reasons for the link."
Because the study focused on older adults with the bulk of participants beingness white, the results may non apply to younger adults together with to people of color. The results ask to hold out confirmed yesteryear other investigators inward dissimilar populations together with through randomized trials to constitute a cause-and-effect human relationship betwixt the eating leafy greens together with reductions inward the incidence of cognitive decline, Morris said.
