Researchers from the University of South Australia found that eating nuts can help boost brain function in aging.
The researchers studied the effect of eating nuts in 4822 participants aged over 55 years.
The results showed that adults who ate more than 10 grams of nuts a day had better brain function, including better thinking, memory and thinking.
"Eating more than 10 grams (or 2 tablespoons) of nuts a day improves cognitive function in the elderly by as much as 60 percent - compared to those who do not eat nuts," said Dr Ming Li, who led the study.
While the reason for this improvement in brain function is still unclear, the researchers suggest it may be associated with its anti-inflammatory and antioxidant effects in the walnut.
"It is known that nuts are rich in healthy fats, protein and fiber with dietary properties that can lower cholesterol and improve cognitive health.
"While there is no cure for decreased age-related cognition, what people eat in their youth provides a positive reflection on their health in adulthood."
