Regular nut eating is linked to sharper brains, according to a recent study published in The American Journal of Clinical Nutrition published this June, that examines the relationships between nut consumption and improvements in cognitive performance.
In the study, researchers evaluated the relationships between nut consumption and changes in cognitive function over a two-year period in a cohort of older persons from Spain who are at risk of cognitive deterioration.
Females made up 48.4% of the 6,630 participants in the study, who were on average 65 years old.
In the lowest and highest consumption categories at baseline, the daily average nut consumption was 1.7 g and 43.7 g, with walnuts being the most consumed.
In comparison to those who consumed the least, those who took the most had higher levels of education, better adherence to the Mediterranean diet, and higher levels of physical activity.
Personal interviews were used to give eight neuropsychological tests, and cognitive tests were standardized to a z-score for each participant using baseline data’s standard deviation.
To investigate changes in cognitive performance, the difference between scores was assessed.
The study’s findings revealed a connection between nut consumption and improvements in cognitive ability over a two-year period.
One serving of nuts per day was linked in multivariable models to better improvements in the clock drawing test and general cognitive performance.
