This was a longitudinal study that examined 4,822 adults 55 years and older from 1991-2006. Investigators studied the relationship between nut intake and cognitive function in older Chinese adults. Dietary surveys were used to capture nut consumption, which included peanuts, walnuts, almonds, sesame seeds, pine nuts, pumpkin seeds, hazelnuts, chestnuts, sunflower seeds, lotus seeds, and watermelon seeds.
Peanuts accounted for 84.2% of all nuts consumed throughout the study. Nut consumption was associated with higher cognitive scores. Nut intake of more than 10g/day was associated with a 40% decreased likelihood of poor cognitive function.
