Conducted at the University of South Australia, the study found that consuming more than 10 grams of nuts per day led to improved mental functioning and thinking, and better memory and reasoning. The study consisted of 4,822 Chinese adults aged 55 or older.
"Population aging is one of the most substantial challenges of the twenty-first century. Not only are people living longer, but as they age, they require additional health support which is placing unprecedented pressure on aged-care and health services," head researcher Dr. Ming Li comments in a release.
According to Dr. Li, the study is the first ever to establish a significant link between a heavy nut diet and improved mental functioning in older adults. The study's authors say their findings could be especially helpful in fighting dementia, a common problem many people face as they enter old age.
