This study suggests a diet rich in fruits, vegetables, nuts, legumes, fish, and dairy may help preserve cognition.
In over 3,000 Chinese older adults tracked for about five years, those who ate more from six protective food groups (fruits, vegetables, nuts, legumes, fish, and dairy) showed slower cognitive decline. People scoring highest on this diet scale declined about 0.42 points per year slower on a cognitive test compared to those scoring lowest. The effect was modest but consistent across different ways of measuring cognition.
