Nut Consumption Associated With Improved Cognitive Function in Mature Adults
Virtually everyone loses memory-making and cognitive abilities as
they age. However, a new study has found that long-term, high nut consumption is
associated with better mental functioning in mature adults.
Participants in the study included 4,822 adults aged 55 and over
who took part in the China Health Nutrition Survey from 1991 to 2006. The
researchers measured global cognitive function in 1997, 2001, 2004, and 2006.
Nut consumption was assessed using the 3-day, 24-hour recall method in 1991 and
1993 and during the cognitive assessments.
The researchers found that participants who ate more than 10
grams (two teaspoons) of nuts per day were 40% less likely to have poor
cognitive function compared to those who did not eat nuts. These results held
even after adjusting for demographic, lifestyle behaviors, BMI, and calorie
The study was conducted by researchers from the University of
South Australia. It was published online ahead of print on October 29, 2018 in The
Journal of Nutrition, Health, and Aging.
