Nuts and seeds contain healthy fats, ﬁber, vitamins, minerals, and antioxidants. In this longitudinal study conducted over a 10-year period, researches evaluated the overall diet, nut intake, and brain function of over 4,000 Chinese people aged 55+. The participants with the highest intake of nuts had a signiﬁcantly higher cognitive function than those who ate a moderate amount of nuts, or no nuts at all. Lifestyle, socioeconomic status, and overall health status did not change this association. This study indicates that a long-term diet rich in nuts may have a protective eﬀect against age-related cognitive decline.
